Frustrated Contracts Act 1988

The Act’s operation turns on a small set of carefully defined concepts and a statutory adjustment algorithm.

Frustration and scope: The Act treats frustration as discharging future obligations (s 6(1)). For sale of goods contracts, the Act expressly treats avoidance under section 7 of the Sale of Goods Act 1895 as frustration (s 3(1)). The Act applies to contracts made after commencement, subject to exclusions (s 4(1)-(2)), and binds the Crown (s 4(3)). The definition of “contract” expressly includes a severable part of a contract (s 3(1)); and the Act states that frustration of a part that is severable does not necessarily frustrate the whole contract (s 5).

Core valuation concepts: The Act defines three mutually related notions that drive the adjustment.

• Contractual benefit. That includes benefits received under the contract and benefits received outside the contract that are either taken into account in calculating the value of the party’s performance or that constitute part of contractual performance (s 3(1), paras (a)-(b)). Where an event prior to frustration diminishes the value of a contractual benefit and that diminution arises from a negligent act or is a risk to be borne by, or insured against by, a particular party, that party is, for the Act’s purposes, treated as having received an equivalent contractual benefit (s 3(4)). This is a specific valuation mechanism that can increase a negligent party’s attributable benefit for the purposes of the statutory adjustment.

• Contractual performance. This covers actual performance of contractual obligations and preparatory acts, and the Act prescribes valuation rules. Where the performance is a monetary payment, the payment amount is the value; where the contract places a value on the performance, that value applies; otherwise value is calculated by reference to costs incurred including a reasonable allowance for the party’s own work, adjusted by an estimated percentage profit or loss if it appears the party would have made a profit or loss had the contract been fully performed (s 3(2)(a)-(c)).

• Contractual return. This is simply contractual benefits less contractual performance, and may be positive, zero or negative (s 3(1)).

Adjustment mechanism: When a contract is frustrated, the Act directs an adjustment so that no party is unfairly advantaged or disadvantaged (s 7(1)). The default mathematical procedure is: assess the value of benefits received up to frustration for each party and aggregate them (s 7(2)(a)); assess and aggregate the value of performance up to frustration for each party (s 7(2)(b)); subtract aggregate performance from aggregate benefits and notionally divide the remainder equally between the parties (s 7(2)(c)); and make an adjustment so each party’s contractual return is equal to that notional figure (s 7(2)(d)). The Act allows apportionment where performance relates to multiple contracts (s 7(3)). The court may adopt a different equitable basis for adjustment where appropriate (s 7(4)).

Relief and remedial powers: To give effect to an adjustment the court may order payment including interest, disposition or sale of property, creation of charges, appointment and powers of a receiver, and incidental matters (s 7(5)). If a party performs after frustration without knowledge that the contract was frustrated, the Act brings that performance into account as if it occurred before frustration (s 7(6)). Joint parties in the same capacity are treated as a single party for adjustment purposes (s 7(7)). An action for adjustment is treated as an action under the contract arising at the time of frustration (s 8).

Dispute resolution reference: “Court” is defined to include an arbitrator (s 3(1)), which broadens the fora in which an adjustment can be litigated.

These concepts structure how values are measured and how courts may equitably reallocate losses and benefits once a contract cannot proceed to performance.

The Act’s immediate audience is the parties to a contract that becomes frustrated after the Act’s commencement. It identifies which legal persons are within scope, who is excluded, and how groups of co-parties are treated.

Parties included: The defined term “association” includes a company or other body corporate (s 3(1)), and “contract” expressly includes severable parts (s 3(1)). The Act applies to the Crown (s 4(3)). A “party” to a contract means a contracting party for purposes of the Act, but expressly excludes a person who is a party only as a guarantor or indemnifier (s 3(1)). Therefore, guarantors and indemnifiers are not treated as parties for the statutory adjustment and valuation mechanisms.

Parties excluded by contract type: The Act contains a relatively specific exclusion list (s 4(2)). The Act does not apply to contracts made before commencement (s 4(2)(a)), to particular categories of maritime contracts (charter-parties other than time charters or demise charters, and carriage of goods by sea, s 4(2)(b)-(c)), to contracts of insurance (s 4(2)(d)), to contracts forming or governing associations or membership rights (s 4(2)(e)), or to partnership agreements (s 4(2)(f)). The effect is that parties in those excluded classes cannot rely on the Act’s statutory adjustment scheme; they must instead rely on other legal rules or their contractual provisions.

Multiple parties and joint capacities: Where two or more persons are jointly parties in the same capacity, they are grouped and treated as a single party for the purposes of adjustment under s 7 (s 7(7)). This affects joint venture partners, co-contractors and similar arrangements, because aggregated benefits and performances will be assessed on a grouped basis rather than individually within the group.

Contractual overrides and severability: The Act applies irrespective of whether frustration produces total failure of consideration, but it is subject to any provision made in the contract itself regarding the consequences of frustration (s 4(1)(a)-(b)). That means parties who have allocated frustration risk by clause will be able to rely on their contract’s terms. The definition of contract including severable parts (s 3(1)), together with the provision that frustration of a particular part does not necessarily entail frustration of the whole if that part is severable (s 5), means that the Act can operate at the level of contract modules or discrete obligations rather than always operating to unwind the entire contractual relationship.

Actors who decide and enforce: The Act contemplates judicial or arbitral determination, because “court” includes an arbitrator (s 3(1)) and an action for adjustment may be commenced before a court as if it were an action under the contract (s 8). The court (or arbitrator) has express powers to make financial and property orders to implement the adjustment (s 7(5)). There are no criminal sanctions in the Act; enforcement is civil and remedial.

Who bears valuation and evidential burdens: The statutory scheme requires parties to have evidence of benefits received and performance carried out up to the frustration date (s 7(2)(a)-(b)); where performance relates to several contracts, apportionment is required in proportions the court considers just (s 7(3)). A party seeking to show it did not know the contract had been frustrated when it performed after the frustration bears the factual footing for protection under s 7(6). The Act thus places evidential and valuation burdens on contracting parties when invoking the statutory adjustment.

The Act creates a set of mutual, default duties and rights that become operative on frustration. These are largely civil entitlements and valuation duties rather than ongoing administrative obligations.

Primary duty: cessation of future obligations. Frustration discharges the parties from all contractual obligations, including obligations that should have been performed but were not performed before the date of frustration (s 6(1)). That is the core automatic effect: future performance obligations are extinguished.

Protected survivals and pre-existing claims: The frustration does not affect obligations that, according to the proper construction of the contract, were intended to survive frustration (s 6(2)(a)). It also preserves rights of action that arose before frustration for damages for breach of contract; however, in assessing such damages the court must take account of the fact of frustration and any consequential adjustment or right to an adjustment under the Act (s 6(2)(b)). Thus parties retain pre-existing breach remedies, subject to adjustment considerations.

Valuation duties when seeking adjustment: Parties invoking the adjustment must have their contractual benefits and contractual performance valued up to the date of frustration (s 7(2)(a)-(b)). Where performance consists of monetary payments the value is the amount (s 3(2)(a)). Where the contract places a value on performance, that value governs (s 3(2)(b)). Where neither applies, the Act prescribes a costing methodology: costs incurred including reasonable allowance for the party’s own work, then adjusted by an estimated profit or loss percentage that would have applied had the contract been fully performed (s 3(2)(c)). The Act requires the valuation of benefits as at the date of frustration (s 7(2)(a)) and permits the taking into account of any effect that the frustrating event has had on the value of contractual benefits (s 3(3)).

Adjustment right and duty to equalise returns: The right established is an entitlement to an adjustment so that no party is unfairly advantaged or disadvantaged (s 7(1)). The default duty flowing from that right is to equalise contractual returns by applying the notional division process set out at s 7(2)(c)-(d). Practically, that will require transferring money, property or other consideration so each party’s contractual return equals the notional figure.

Remedial powers to enforce adjustments: A court may make orders to effect the adjustment, including for payment of money (with interest), disposition, sale or realisation of property, creation of charges on property, appointment and powers of receivers, and incidental matters (s 7(5)). These powers give effect to the right to adjustment by converting it into enforceable remedies.

Rights preserved for special circumstances: If a party purportedly performs after frustration without knowledge of the frustration and could not reasonably have been expected to know, the value of that performance and any consequent benefits will be accounted for as if they occurred before frustration (s 7(6)). This protects unwitting performers from losing the value of their efforts and ensures proper accounting.

Discretionary judicial right: The court retains a discretionary right to adopt a different equitable basis for adjustment where that would be more equitable in the circumstances (s 7(4)). This gives the court a corrective power to depart from the Act’s default arithmetic if application would produce injustice.

Action timing and nature: An action for adjustment may be commenced as if it were an action under the contract that arose at the time of frustration (s 8). That is a procedural right affecting how claims may be brought in court or before an arbitrator, though the Act itself does not set specific limitation periods.

Excluded matters: The above duties and rights do not apply to contracts excluded by s 4(2), nor to contracts made before commencement of the Act (s 4(2)(a)). Parties may also contractually prescribe consequences of frustration that displace the statutory default (s 4(1)(b)).

The Act establishes civil enforcement mechanisms and remedial orders; it does not create criminal penalties or administrative fines. Enforcement is exercised through judicial or arbitral processes.

No criminal sanctions: The Act contains no offences, fines or penal provisions. All remedies are civil and remedial in character as spelled out in the relevant sections.

Remedial powers of court or arbitrator: The primary enforcement mechanism is an adjustment order made by a court (including an arbitrator by definition, s 3(1)), following the statutory valuation process or on a different equitable basis approved by the court (s 7(4)). To implement an adjustment the court may order payment of money, including interest (s 7(5)(a)); order the disposition, sale or realisation of property (s 7(5)(b)); create a charge on property (s 7(5)(c)); appoint a receiver and define the receiver’s powers (s 7(5)(d)); and make any incidental or ancillary orders required to give effect to the adjustment (s 7(5)(e)). Those powers are administrative and proprietary enforcement tools rather than penal measures.

Procedure and timing: An action for adjustment and consequential orders may be commenced before a court as if it were an action under the contract that arose at the time of frustration (s 8). This provision assimilates the statutory claim procedurally to a contract claim commencing at the frustration date. The Act does not itself set out limitation periods or procedural rules; those will be governed by the court rules and other applicable procedural law. The s 8 mechanism, however, is a substantive foothold to commence proceedings seeking statutory adjustment.

Accounting and valuation enforcement: The Act’s adjustment framework requires valuation of benefits and performance at the date of frustration (s 7(2)(a)-(b), s 3(2)). Disputes over valuation, apportionment where performance spans several contracts (s 7(3)), or the contribution of negligent acts that diminished value (s 3(4)) will be matters for determination by the court or arbitrator. Enforcement thus often requires expert evidence and accounting work, and the court’s remedial powers allow it to convert valuation outcomes into enforceable financial or proprietary orders (s 7(5)).

No express private penalties for non-compliance: The Act does not provide for statutory interest rates beyond allowing interest to be ordered (s 7(5)(a)), nor does it specify civil penalties for failure to comply beyond the ordinary consequences of contempt, execution, or enforcement of court orders under other laws. The Act therefore relies on courts’ ordinary enforcement machinery once an adjustment order is made.

Arbitral enforcement: Because “court” includes an arbitrator (s 3(1)), parties who have submitted disputes to arbitration can obtain an adjustment through arbitration, and then enforce arbitral awards according to the relevant arbitral enforcement regime. The Act thereby interfaces with both litigation and arbitration enforcement pathways.

The Act is drafted to operate alongside other statutory and contractual regimes; it makes explicit references to some external rules and leaves others to interact by operation of general law and practice.

Reference to Sale of Goods Act 1895: The Act expressly treats avoidance under section 7 of the Sale of Goods Act 1895 as frustration for contracts for the sale of goods (s 3(1)). That ties the Act’s adjustment machinery to a specific statutory mechanism in sale-of-goods law where the sale is avoided. The result is that avoidance may trigger the Frustrated Contracts Act’s valuation and adjustment processes.

Exclusions that leave other regimes to govern: The Act does not apply to contracts of insurance (s 4(2)(d)), to certain maritime contracts and sea carriage (s 4(2)(b)-(c)), to partnership agreements (s 4(2)(f)), or to contracts constituting associations or laying down rules of membership (s 4(2)(e)). By excluding these categories, the Act leaves adjustment following frustration in those fields to be determined by other statutory schemes, contractual terms or established commercial practice relevant to those domains.

Contractual variance permitted: The Act applies subject to any provision made in the contract as to the consequences of frustration (s 4(1)(b)). That explicitly preserves the primacy of express contractual allocation of risk and remedies for frustration, so long as the contract itself addresses the issue. This provision creates a direct interaction: the statutory default will yield to concrete contractual terms.

Courts and arbitration: The Act defines “court” to include an arbitrator (s 3(1)). Consequently, the Act’s adjustment remedy can be pursued in arbitral forums as well as in litigation. The procedural effect of s 8, treating an action for adjustment as if it were an action under the contract arising at the time of frustration, meshes with ordinary contractual remedies and procedural rules, while not substituting its own limitation regime.

Remedial tools and property law: The court’s powers to order disposition or sale of property, creation of charges, and appointment of a receiver (s 7(5)(b)-(d)) necessarily interact with property, secured transactions and insolvency regimes. The Act permits the creation of charges and receivership orders to implement statutory adjustments; those measures will operate alongside the statutory rules that govern priorities, registration of charges and receivership powers in other statutes and under general law.

Interaction with remedies for breach: The Act preserves rights of action for pre-frustration breach (s 6(2)(b)), but instructs courts, when assessing damages, to take account of the fact of frustration and any resulting adjustment (s 6(2)(b)). Thus the Act sits as a modifier of damage assessment for pre-frustration breaches; courts must incorporate the implications of statutory adjustment into damage awards for earlier breaches.

Crown status and public law: The Act expressly binds the Crown (s 4(3)), which means public authorities are within the statutory adjustment regime rather than immune from it. That status intersects with public law doctrines and with any statutory powers the Crown might have in other contexts, but the Act simply places the Crown within the same adjustment rules as private parties.

Valuation and accounting standards: The Act prescribes valuation methods (s 3(2)-(4)) but does not adopt or mandate particular accounting standards; practitioners must apply the prescribed tests (monetary amount, contractual valuation, or cost-plus/profit estimate) and the court may address valuation disagreements. Where performance relates to multiple contracts, the court may apportion value between contracts on terms it considers just (s 7(3)), which implicates principles of apportionment within contract law and factual allocation.

In summary, the Act is designed to interact with existing commercial and property law: it refers to and incorporates a sale-of-goods avoidance mechanism, carves out sectors where other regimes apply, defers to contractual allocation of risk, brings arbitration within its ambit, and equips courts with property and enforcement tools that will operate alongside the relevant property and enforcement statutes.

The legislative history provided in the Act is concise. The Frustrated Contracts Act 1988 was enacted by the Parliament of South Australia, received assent on 10 March 1988 and commenced on 1 April 1988 (Gazette 31.3.1988 p 762) as the principal Act (Legislative history entry for 1988 No 11). The Act’s short title is Frustrated Contracts Act 1988 (s 1).

The material notes that section 2 was omitted under the Legislation Revision and Publication Act 2002. No other amendments are recorded in the supplied text. The Act’s notes refer readers to the Index of South Australian Statutes or the official legislation website for further information and subordinate legislation (Notes).

Practical implications of the amendment history supplied: the Act’s substantive provisions as reproduced reflect the version after the omission of s 2 by the Legislation Revision and Publication Act 2002. Because the legislative history printed here only records the principal Act and the omission of s 2, there is no further recorded statutory modification, additional schedules, or later substantive amendment in the supplied source. The limited amendment record suggests that the Act’s core mechanics (definitions, adjustment algorithm, remedial powers) have been stable since commencement, at least insofar as this source shows.

The Act binds the Crown (s 4(3)), and the principal Act entry confirms commencement. The omission of s 2 under a general Legislation Revision and Publication Act is a technical change typical of statute revision exercises; the text reproduced is therefore the operative text post-revision. For a complete legislative history beyond what is included here (for example, any subsequent amendments, repeals, or regulations made under the Act), the Act itself directs readers to the index and the official legislation site (Notes). The supplied material contains no other amendment entries, so there are no further legislative changes recorded in this source to analyse.

The source supplied contains no reported judicial decisions, case names or summaries; there are no entries for litigation or judicial interpretation in the legislative history portion reproduced. The Act’s text therefore must be the sole authority for present purposes; it does not provide examples of how courts have applied the statutory formula, nor does it cite particular cases.

Despite the absence of reported litigation in this source, the Act creates multiple litigation-prone issues by design. The Act contemplates that disputes will be decided by courts or arbitrators because it defines “court” to include an arbitrator (s 3(1)) and expressly allows an action for adjustment to be commenced as if it were an action under the contract arising at the time of frustration (s 8). Typical areas where litigation would arise under the Act, and where courts would be called upon to make fact-sensitive determinations, include:

• Valuation disputes. The Act requires assessment of contractual benefits and contractual performance as at the date of frustration (s 7(2)(a)-(b)), using a tiered valuation method for performance (s 3(2)). Disputes will arise over proper valuation methods, reasonable allowances for work done, and the percentage profit or loss that would have obtained had the contract been fully performed.

• Apportionment when performance relates to multiple contracts. Where performance is referable to several contracts, the Act requires apportionment of the value of that performance between the contracts in proportions the court considers just (s 7(3)). Litigation will be triggered when parties disagree about fair apportionment.

• Application of the negligence/diminution rule. The Act treats an event that diminishes the value of contractual benefits, where the event arises from a particular party’s negligent act or omission or is a risk that party ought to have borne, as a contractual benefit to that party equal to the diminution (s 3(4)). That counterintuitive adjustment will generate disputes about causation, responsibility, customary risk allocation, and the quantification of diminution.

• Whether a contractual term displaces the Act’s default. Because the Act is subject to contractual provisions about the consequences of frustration (s 4(1)(b)), litigation may be necessary to determine whether contractual language validly and effectively displaces the statutory scheme.

• Treatment of post-frustration performance. The Act brings into account performance carried out after frustration by a party who did not know and could not reasonably be expected to have known of the frustration, treating that performance as if it had occurred before frustration (s 7(6)). Litigation will arise where parties contest whether a performer had the requisite knowledge or reasonable care.

• Grouping of joint parties. The provision treating jointly acting parties as a single party for adjustment (s 7(7)) may prompt disputes where individual co-parties claim differing entitlements or where internal contribution or subrogation questions arise.

• Choice of equitable basis. The Act empowers the court to adopt a different equitable basis for adjustment if the statutory arithmetic is not the most equitable (s 7(4)). Disputes will occur at the interface between statutory formula and equitable discretion.

While the Act permits arbitration (s 3(1)), and an adjustment action may be commenced as a contract action at the date of frustration (s 8), the supplied material does not record any arbitral awards or judicial decisions that interpret specific provisions such as the treatment of negligent diminution (s 3(4)) or the calculation of profit or loss under s 3(2)(c). Practitioners should therefore expect that many of the Act’s valuation and equitable choices are likely to be fact-driven and that litigation will focus on expert valuation, contractual construction as it bears on survivals (s 6(2)(a)), and the interplay between the statutory formula and contractual clauses (s 4(1)(b)).

Because the source contains no reported cases, no jurisdictional patterns, or appellate developments are available here; the Act’s text provides the only authoritative guidance in this document.

The Act appears concise, but several provisions can produce unexpected outcomes if practitioners and parties do not attend to their mechanics.

Contractual overrides and pre-commencement contracts. The Act applies subject to any contractual provision as to the consequences of frustration (s 4(1)(b)). That means carefully drafted contractual clauses will defeat the statutory default. Conversely, contracts entered before the Act’s commencement are outside the Act altogether (s 4(2)(a)). Parties who assume the Act will always apply may be surprised to find pre-existing contracts or express allocation clauses preclude statutory relief.

Frustration of severable parts. The Act treats “contract” as including a severable part (s 3(1)) and provides that frustration of a particular part that is severable does not necessarily frustrate the whole contract (s 5). The practical effect is that partial frustrations can produce partial statutory adjustments rather than automatic unwinding of an entire agreement. Parties should therefore isolate deliverables and consider severability when drafting to control whether the statutory scheme will operate at a granular level.

Definition of party excludes guarantors and indemnifiers. The Act excludes persons who are parties only in their capacity as guarantors or indemnifiers from the definition of party to the contract for the Act’s purposes (s 3(1)). A guarantor or indemnifier thus cannot claim under the Act as a contracting party; their remedies will be governed by other contract or indemnity principles. Practitioners should not assume security or guarantee roles are swept into the adjustment regime.

The negligent-diminution valuation rule. Where an event occurring before or resulting in frustration diminishes the value of a contractual benefit, and that event is due to a party’s negligence, is a risk that party should have borne, or is extraneous to the contract but attributable to the party, the Act requires the court to treat that party as having received a contractual benefit equal to the diminution (s 3(4)). This counterintuitive accounting will increase the notional benefit attributed to a culpable party, which may in turn require a larger adjustment against them. Parties causing diminution by negligence cannot simply argue that the diminution reduces their exposure; the Act treats the diminution as a benefit to them for adjustment purposes.

Equal sharing of the remainder. The statutory default divides the aggregate surplus (aggregate benefits minus aggregate performance) notionally in equal shares between the parties (s 7(2)(c)). This equal-division approach may produce surprising transfers in multi-party or multi-capacity arrangements, particularly where parties’ pre-frustration inputs and benefits are asymmetric. The court may adopt a different basis under s 7(4), but litigating for a different basis is itself an expense and litigation risk.

Valuation complexity and evidential burden. The Act prescribes valuation methods (s 3(2)) and requires valuation as at the date of frustration (s 7(2)(a)). Where performance is neither monetary nor contractually valued, parties must quantify costs, include reasonable allowances for work done, and estimate the profit or loss percentage the party would have made (s 3(2)(c)). These computations are fact-intensive and demand documentary and expert evidence. Where performance spans several contracts, apportionment “in such proportions as may be just” is required (s 7(3)), which raises further factual disputes and litigation costs.

Post-frustration performance protection dependent on ignorance. A party who performs after frustration can have that performance valued as if it occurred before frustration if they did not know and could not reasonably be expected to have known the contract had been frustrated (s 7(6)). The protection depends on both subjective ignorance and an objective standard of reasonable knowledge; those are contested factual matters and present a litigation risk for parties who undertake performance close to the frustration date.

Grouping of joint parties consolidates liability. When persons are jointly parties in the same capacity they are treated as a single party for adjustment purposes (s 7(7)). This can concentrate obligations and dilute arguments about internal contribution unless the joint parties have specifically agreed allocation mechanisms.

Arbitral forum available, but enforceability nuances. The Act’s definition of “court” to include an arbitrator (s 3(1)) makes arbitration available. However, the Act does not itself address enforceability of arbitral adjustments beyond allowing arbitration to function as a court for Act purposes; parties should therefore be aware that enforcement of awards will depend on the general arbitral enforcement regime, which the Act does not modify.

No criminal or administrative penalty , reliance on civil enforcement. The Act provides remedial powers but no penal sanctions. The only lever to enforce compliance is the civil court or arbitral award, and the court’s ancillary powers to order sales, charges and receivers (s 7(5)). If a party lacks assets, the statutory remedy will still be limited to ordinary civil enforcement consequences.

Limited recorded amendment and litigation guidance in the source. The supplied legislative history is sparse and contains no reported judicial interpretations in this material. That lack of binding interpretative history means that many of the Act’s valuation and equitable choices are left to judicial fact-finding and discretion, creating unpredictability until courts or tribunals generate authoritative decisions.

Complying with the Act requires preparation for valuation exercises, attention to contract drafting, record-keeping, and understanding the procedural routes for seeking or defending an adjustment.

1. Contract drafting and allocation of risk

• If parties intend to displace the statutory default, they must include clear contractual provisions dealing with frustration and its consequences, because the Act applies subject to any contractually prescribed consequences (s 4(1)(b)). Draft clauses should specify allocation of benefits, termination mechanics, and any liquidated sums or restitution arrangements to avoid the statutory equalisation method if that is the intention.

2. Know whether the Act applies

• Confirm whether the contract falls within the Act’s scope. The Act does not apply to contracts made before commencement (s 4(2)(a)), to specified maritime contracts and sea carriage (s 4(2)(b)-(c)), to contracts of insurance (s 4(2)(d)), to contracts forming associations or membership rules (s 4(2)(e)), or to partnership agreements (s 4(2)(f)). If the contract is excluded, a different legal regime will apply.

3. Preserve contemporaneous records

• The statutory adjustment depends on valuation at the date of frustration (s 7(2)(a)-(b)) and on proof of costs, benefits received and preparatory work (s 3(2)(c)). Parties should retain invoices, wage and cost records, receipts, correspondence, evidence of benefits conferred (payments received, services rendered), and any contemporaneous commercial communications indicating knowledge or notice relating to the frustrating event. This evidentiary material will be central in any court or arbitral valuation.

4. Evidence of knowledge for post-frustration performance

• If a party performs after frustration and wishes to rely on s 7(6) so that the performance is treated as pre-frustration, it must be able to establish it did not know and could not reasonably be expected to have known of the frustration. That will entail documentary and witness evidence showing lack of notice and reasonable grounds for belief that performance was still required.

5. Valuation methodology preparation

• Where performance is not a monetary payment and no contractual valuation is present, prepare a cost schedule including direct expenditures, a reasonable allowance for the contracting party’s own labour, and a reasoned estimate of the percentage profit or loss the party would have expected had the contract been fully performed (s 3(2)(c)). Engage financial and accounting experts to prepare these estimates, because they are likely to be contested.

6. Anticipate apportionment issues

• If performance relates to multiple contracts, prepare documentation to justify a proposed apportionment of performance value between contracts (s 7(3)). Where joint parties act in the same capacity, prepare to coordinate as they will be treated as a single party under s 7(7).

7. Consider alternative dispute resolution

• Because “court” includes an arbitrator (s 3(1)), and an action for adjustment can be treated as an action under the contract arising at the time of frustration (s 8), parties with arbitration clauses can pursue adjustment through arbitration. Consider whether arbitration is desirable for speed, confidentiality and specialist expertise. Ensure that arbitration agreements are sufficiently broad to cover statutory adjustment claims.

8. Prepare for equitable arguments

• The court may adopt a different equitable basis where that is more just (s 7(4)). If the statutory arithmetic would produce an inequitable result, prepare legal and factual submissions to persuade the tribunal to exercise this discretion. Conversely, where a party prefers the statutory formula, prepare arguments defending its application.

9. Plan enforcement and remedies

• Be ready to seek or respond to court orders under s 7(5) for payment, property disposition, creation of charges and receivership. If seeking security or enforcement, consider preliminary injunctions or preservation orders as allowed by court practice. Remember that the Act itself does not create penal sanctions; enforcement will rely on the court’s usual powers and ancillary statutory regimes governing property and security.

10. Liaise with third-party stakeholders

• If third parties hold assets over which a charge or sale is sought, or if a receiver’s appointment would affect third-party rights, identify and notify stakeholders early. The court may order creation of charges or appointment of receivers (s 7(5)(c)-(d)), and those processes interact with third-party property rights.

11. Corporate and Crown considerations

• The Act binds the Crown (s 4(3)), so public authorities are subject to the same adjustment regime. Corporate parties are included via the definition of association (s 3(1)). Companies should involve in-house counsel and finance teams early to coordinate valuation and enforcement strategies.

12. Timing consideration for commencing action

• An action for adjustment may be commenced as if it arose under the contract at the time of frustration (s 8). Practitioners should be mindful of relevant limitation periods and procedural requirements applicable to contract actions in their forum, and act promptly to preserve rights.

Following these steps will not guarantee outcomes, because the Act leaves valuation and equitable choices to tribunals in contested cases, but they align compliance and litigation readiness with the Act’s statutory mechanics.
