The Act casts a wide net. Any person who owns, buys, sells, mortgages, leases or holds an interest in South Australian land is directly affected. Practising lawyers engaged in conveyancing, mortgage lending or trust advice must master its formality, implication and enforcement rules. Banks and other authorised deposit-taking institutions exercising powers of sale or appointing receivers act under ss 47–53 and are subject to the notice regime in s 55A when the borrower is a natural person and the land is used domestically or agriculturally.

Trustees for sale, personal representatives, guardians of mentally incapacitated persons and committees act under the vesting-order and trustee-deeming provisions (ss 18–19, 75, 91). Co-owners seeking partition or sale invoke Part 8. Settlors and testators creating future interests benefit from the abolition of perpetuities (s 61) but must still navigate the Court’s 80-year variation power. Infants entering housing finance contracts with prescribed lenders receive statutory validation of what would otherwise be voidable obligations (s 24A). Alien friends (now all non-citizens lawfully present) are placed on the same footing as natural-born subjects (s 24). Bodies corporate may hold property as joint tenants with the consequence that the property passes by survivorship on dissolution (s 24C).

The Crown is bound except in relation to distress (s 120) and may have its real estate interests sold by Court order (s 114). Purchasers for value without notice receive statutory protection against notice of trusts affecting proceeds of sale (s 21) and against unregistered lis pendens (s 11). Mortgagors obtain rights to sue in their own name for trespass or recovery of rent (s 14), to require transfer rather than reconveyance (s 45), and to receive an accounting on sale (s 50).

Duties fall most heavily on mortgagees. Before exercising power of sale they must serve notice (s 48(a)), and for domestic/agricultural mortgages they must first serve a default notice giving one month (or longer stipulated period) to remedy the breach and, if claimed, to pay the mortgagee’s reasonable costs (s 55A(1)). A mortgagee in possession or exercising receivership owes equitable duties of good faith and to obtain proper price, although the Act itself states the mortgagee is not answerable for involuntary loss (s 51(3)). Trustees for sale must recognise the statutory trust and the purchaser’s statutory immunity from inquiry into the trusts (s 21).

Rights are conferred liberally. A mortgagor entitled to possession may sue in his own name (s 14). Any person may take the benefit of a covenant although not named as party (s 34). Rights of pre-emption affecting legal estates may be released (s 20). A tenant for life without impeachment of waste may not commit equitable waste unless the instrument expressly permits it (s 12). After 26 October 1911 no easement of light can be acquired by prescription or lost grant (s 22). A donee of a gift subject to an illegal condition takes the gift free of the condition unless the donee consented to it (s 23).

Parties to deeds and instruments gain certainty from the statutory rules on execution, attestation, delivery and conditional execution (ss 41, 41AA). The abolition of the doctrine of escrow (s 41AA(7)) removes a former source of uncertainty. Receivers appointed by mortgagees are deemed agents of the mortgagor, limiting the mortgagee’s direct liability (s 53(2)).

The Act is not primarily criminal. Enforcement is civil. Breach of the writing requirement in s 26 renders the contract unenforceable by action, though not void. Defective execution of a deed may still be saved if external evidence shows intention to be bound (s 41(4)). An unauthorised exercise of the power of sale gives the purchaser indefeasible title but exposes the mortgagee to damages (s 49(2)).

Section 55A provides the principal statutory sanction in the mortgage context: rights of sale, foreclosure, possession or receiver appointment are not enforceable until the prescribed notice is given and not complied with. Courts may dispense with notice (s 55A(2a)) or grant relief on equitable terms, reinstating the mortgagor as if no breach had occurred (s 55A(3)). Wrongful appointment of a receiver or improper sale may sound in damages or equitable compensation, although the Act limits the mortgagee’s liability for involuntary loss (s 51(3)).

Voidable dispositions under ss 86–87 are set aside at the instance of prejudiced creditors or subsequent purchasers. The Court’s powers to make vesting orders (ss 18, 19, 46, 89, 90) or vary dispositions after 80 years (s 62) are discretionary and exercised on application by interested persons, including the Attorney-General.

The Act is expressly subordinate to the Real Property Act 1886 (RPA) where land is under the Torrens system (s 6). Mortgage provisions apply to registered land subject to RPA registration and priority rules (s 56). Vesting orders and appointments of trustees interact with the Trustee Act 1936, which supplies the definitional content of “trustee” for the purposes of ss 18, 19, 75 and 91.

The Guardianship and Administration Act 1993 supplies the meaning of “mentally incapacitated person” (s 7). Execution provisions must be read with the Electronic Communications Act 2000 (Cth) and any State regulations governing electronic deeds. The abolition of perpetuities (s 61) dovetails with the Succession Act 2023 (once commenced) and the rule in Saunders v Vautier (expressly preserved by s 62A).

Apportionment rules (Part 7) interact with the law of deceased estates and trusts. The fraud provisions (Part 9) sit alongside the general law of fraudulent conveyances and the Bankruptcy Act 1966 (Cth). Court jurisdiction under the Act is allocated among Supreme Court, District Court and Magistrates Court according to the value of the property (s 7 definition of “court”).

Recent amendments have aligned the Act with Commonwealth same-sex marriage reforms (Statutes Amendment (Legalisation of Same Sex Marriage Consequential Amendments) Act 2019) and married persons’ separate legal personality (Married Persons (Separate Legal Status) Act 2019).

The most significant substantive change remains the 1996 substitution of Part 6 (Law of Property (Perpetuities and Accumulations) Amendment Act 1996). The common-law rule against perpetuities and the rule against accumulations were repealed because they were technical, uncertain in application to modern trusts, and frustrated legitimate estate planning. The 80-year “wait and see” variation power was introduced to give courts flexibility while still preventing indefinite tying-up of property.

Execution rules were modernised in 1989 (s 41) and again in 2025 (ss 41(1)(d), 41A(2)–(2a)) to permit electronic execution and to transfer the power to declare bodies from the Governor to the Minister. These changes reflect the shift to digital commerce and reduce administrative burden.

The 2019 amendments removed gendered language (s 100), deleted obsolete married-women’s property provisions (ss 92–99, 105–107, 109, 111) and updated spousal trust rules to reflect separate legal personality and marriage equality. The Succession Act 2023 will, from 1 January 2025, repeal ss 114(3) and 115, further pruning obsolete Crown and intestacy cross-references.

Collectively these amendments demonstrate a legislative policy of pruning feudal remnants, facilitating digital transactions, protecting consumers in mortgage enforcement, and giving courts broader equitable jurisdiction to vary outdated trusts.

Because the Act is largely facilitative, reported challenges tend to cluster around three areas: the limits of the mortgagee’s power of sale, the scope of the new perpetuities regime, and the interaction between statutory implied covenants and express contractual terms.

In mortgage litigation the requirement in s 55A that notice both allege breach and quantify reasonable costs has generated dispute about sufficiency of particularity. Courts have emphasised that the notice must enable the mortgagor to understand exactly what must be remedied. The statutory immunity conferred on purchasers by s 49(2) has been tested where mortgagees sell to related parties; the section prevents impeachment of title but does not preclude equitable claims for breach of duty.

The 1996 perpetuities reforms have so far produced little appellate litigation, largely because the Court’s variation power under s 62 is broad and discretionary. The note to s 62A expressly endorses the continuing operation of Saunders v Vautier even where beneficiaries’ interests are successive, provided they are unanimous and sui juris. Future controversy is likely to centre on what constitutes the “spirit of the original disposition” when the Court is asked to accelerate vesting.

The implied covenants in Schedule 2 have been construed strictly; a vendor who conveys “as beneficial owner” without qualification attracts the full statutory liability even if the contract contains an “as is” clause, unless the conveyance itself expresses a contrary intention (s 42(3) prior to its 2019 repeal, and the opening words of each covenant).

Most practitioners still miss several traps:

• The statutory power of sale under s 47 is available only if the mortgage is made by deed; an equitable mortgage requires a court order (s 43).
• Section 55A applies whenever the mortgagor is a natural person and the land is appropriated to domestic or agricultural use; a statutory declaration by the mortgagor that it is not so appropriated is conclusive, but once made the lender cannot later rely on s 55A protections.
• The abolition of escrow in s 41AA(7) means conditional delivery of a deed now operates under a statutory regime that cannot be recalled by the grantor once the condition is fulfilled, even if the condition is within the grantor’s control, unless the condition is expressed in the instrument itself and the other party has not relied on it.
• A purchaser from trustees for sale is statutorily protected from inquiring into the trusts affecting proceeds (s 21), but only if the trustees are expressly described as “trustees for sale” and the trust is an immediate binding trust for sale; a power to postpone does not prevent it being immediate.
• Electronic deeds under s 41(1)(d) still require attestation in accordance with s 41(2); many practitioners assume that clicking “I agree” on a platform satisfies the witness requirement.
• The 80-year vesting power in s 62 cannot be used for charitable trusts, superannuation trusts or unincorporated associations; attempts to vary such trusts under the Act will fail.
• Apportionment under Part 7 does not apply to insurance policy sums (s 67) or where the instrument expressly excludes apportionment (s 68).

Compliance begins with due diligence on title and proper documentation. For land contracts, ensure a sufficient memorandum signed by the party to be charged or an agent authorised in writing (s 26). When preparing transfers or mortgages, use the correct form of words—“as beneficial owner”, “as trustee”, etc.—if the implied covenants are desired, or expressly negate them (s 42(4)).

Mortgagees must adopt a compliant default notice under s 55A before any enforcement action; the notice should particularise the breach, stipulate a remedy period of at least one month, and, if costs are claimed, set out a reasonable sum. When selling, obtain independent valuation evidence, market the property adequately, and apply proceeds strictly in the order set out in s 50.

Trustees for sale should document decisions to sell or postpone and ensure any contract of sale recites their capacity. When advising on future interests post-1996, draft without regard to the old perpetuities rule but include a fallback clause permitting the Court to vary under s 62 if unforeseen remoteness arises.

For electronic instruments, use a platform that records the signatory’s intention to execute as a deed, ensures the document is expressed to be a deed, and provides for witnessing in accordance with s 41(2). Retain metadata evidencing the time and manner of execution.

In partition or sale applications under Part 8, serve all interested parties or obtain an order dispensing with service and publishing advertisements (s 72). When acting for infants or persons under disability, obtain Court approval before requesting sale or giving undertakings to purchase (s 82).

Finally, maintain a register of notices and use registered post where the Act deems service effective (s 112(4)). Where doubt exists, apply to the Court for vesting orders or directions rather than risk invalid title; the broad jurisdiction conferred by ss 18, 19, 46, 89 and 90 is designed to cure technical defects. Regular file audits against the current consolidated version (including all 2025 amendments) are essential, as the legislative history table shows more than 25 amending Acts.
