The Act primarily affects three groups: eligible applicants, personal representatives (administrators and executors), and beneficiaries under wills or intestacy.

Eligible applicants are defined in s.7(1). The widest category is the person married to or in a de facto relationship with the deceased immediately before death (s.7(1)(a)). Former spouses or de facto partners entitled to maintenance at the date of death are covered (s.7(1)(b)). Children living at death or born within 10 months after are eligible without further proof of dependency (s.7(1)(c)). Grandchildren must satisfy one of three limbs: maintenance by the deceased immediately before death, predecease of their parent who was a child of the deceased, or birth within 10 months after death where their parent predeceased (s.7(1)(d)). Stepchildren fall into two distinct categories: those maintained or entitled to maintenance immediately before death (s.7(1)(ea)), and those whose deceased parent transferred or was obliged to transfer property to the deceased exceeding the prescribed amount (s.7(1)(eb)). The latter category only applies to deaths on or after the 2011 amending Act’s commencement (s.7(2A)). Parents are eligible only where the relationship was admitted by the deceased while of full age or established in the deceased’s lifetime (s.7(1)(e)).

Section 4(4) restricts recognition of parent-child relationships traced through that link to cases where parentage was admitted or established against the parent in the parent’s lifetime; this does not apply to artificial conception relationships under the Artificial Conception Act 1985 (s.4(4a)). “Child” and “grandchild” expressly include illegitimate children (s.4(1)). “Stepchild” is narrowly defined by reference to the date the deceased married or entered a de facto relationship with the stepchild’s parent (s.4(1)).

Administrators and executors are affected by protection provisions (ss.11, 20), the obligation to receive notice of applications (s.12(1)), the possibility of substitution for misconduct (s.18), and the requirement to implement Court orders including notation on the grant (s.14(4)). They are not obliged to inquire whether any person might claim under the Act (s.20(2)).

Beneficiaries under the will or intestacy have their entitlements potentially reduced. They may appear on applications, oppose orders, and apply to vary orders that cause them hardship (s.15(1)(b)). Where a class fund is created, their interests may be pooled and applied at trustee discretion (s.13). Burden of orders is borne rateably unless the Court orders otherwise (s.14(2)-(3)).

The Crown is bound (s.6A), so the Act can affect estates in which the State has an interest. The Public Trustee, when acting as executor or administrator or having filed an election to administer, falls within the definition of “administrator” (s.4(1)).

Applicants have the right to apply for provision (s.6(1)), interim relief (s.7A), increased provision (s.16), and to seek rescission or reduction of existing orders where hardship is caused (s.15). They enjoy the right to have their application treated as made on behalf of all eligible persons in certain circumstances (s.12(2)). Rights are subject to strict time limits, although the Court’s leave power is preserved (ss.6(7), 7(2)-(3)).

The Court’s rights and duties are central. It must be “reasonably satisfied” of grounds (s.4(3)), may refuse relief on character or conduct grounds (s.6(3)), and must consider the effect of intestacy rules without assuming they are always adequate (s.6(2)). When making orders it must specify the fund and method of payment (s.14(1)), direct notation on the grant (s.14(4)), and may order costs as it thinks just (s.14(6)). It holds powers to appoint substitute administrators (s.18), create class funds (s.13), vary orders (ss.15-17), and give consequential directions (s.14(7)).

Administrators have duties to distribute properly but enjoy statutory protections. They cannot be sued for distributions made without notice of an application (s.20(1)), for urgent distributions to dependants (s.11), or where a capable person has given written consent or waiver (s.20(4)). Notice of intended application lapses after three months if the application is not filed, or after 12 months from entitlement to administer, whichever is sooner (s.20(5)). They are under no obligation to inquire about possible claimants (s.20(2)). Where they are replaced, their liabilities transfer to the new administrator (s.18(2)).

Beneficiaries have the right to be heard, to seek variation of orders causing hardship (s.15), and to have rateable burden applied unless otherwise ordered (s.14(2)). Persons taking under an order must be served with applications to vary it (ss.15(2), 6(6)).

Evidentiary rights are enlarged by s.21A. Statements of the deceased are admissible as to facts that would have been admissible had the deceased given direct oral evidence, subject to the detailed safeguards in that section concerning form, weight, credibility and inconsistency.

The Act creates no criminal offences or monetary penalties. Enforcement is civil. Orders are enforced through the Court’s inherent contempt powers and by treating the provision as a codicil or modification of intestacy (s.10). Once made, the relevant portion of the estate is held subject to the order (s.14(5)).

Failure to comply with a Court direction—such as producing a grant for notation (s.14(4)) or complying with consequential directions (s.14(7))—exposes a party to contempt proceedings. An administrator found guilty of abuse of office or dereliction of duty may be removed and replaced (s.18(1)), with all rights and liabilities automatically vesting in the replacement.

Costs are at the Court’s discretion (s.14(6)). An order under the Act can be enforced as if it were a judgment. Where a class fund is created, the trustee’s discretionary powers are supervised by the Court’s ability to give directions under s.13(2) and by its Trustees Act 1962 powers.

Protection provisions (ss.11, 20) operate as defences to actions that might otherwise lie against administrators. Conversely, a mortgage or assignment given before an order is made is declared to have no force, validity or effect (s.19), providing a statutory nullification rather than a penalty.

The Act is not standalone. Section 4(1) imports the meaning of “administration” and “administrator” from the Administration Act 1903. It repeatedly cross-refers to the Trustees Act 1962: s.8 allows an order under s.65 of that Act in lieu of a family provision order; s.9 requires regard to s.65(8); s.13(4) permits exercise of s.89 powers; s.17 authorises commutation and exoneration mechanisms that sit within the trusteeship framework.

Section 5 preserves the effect of orders made under the repealed Testator’s Family Maintenance Act 1939 and continues pending proceedings. Section 5(2) extends ss.15-17 to certain pre-1972 orders under the Guardianship of Infants Act 1920.

Evidentiary rules in s.21A expressly supplement the hearsay exceptions in the Evidence Act 1906 (s.21A(13)) while preserving the common-law rules against hearsay except to the extent modified. The definition of “Court” means the Supreme Court or a judge (s.4(1)), and procedural rules are made under the Supreme Court Act 1935 (s.21).

Relationship recognition interacts with the Artificial Conception Act 1985 (s.4(4a)) and earlier equality of status legislation (reflected in the 2003 amending Act). De facto partner status draws on definitions in the Interpretation Act 1984 as amended by the Acts Amendment (Lesbian and Gay Law Reform) Act 2002.

The Act binds the State and, so far as legislative power permits, the Crown in all capacities (s.6A). It does not displace the general law of undue influence, testamentary capacity or equitable claims such as constructive trusts, although in practice family provision claims often run alongside or in substitution for such claims.

Section 21B authorises regulations prescribing the amount for s.7(1)(eb) stepchild claims; that amount is therefore capable of executive adjustment without further primary legislation.

The most substantial amendments were effected by the Inheritance (Family and Dependants Provision) Amendment Act 2011, which renamed the statute the Family Provision Act 1972 (note 3 to the compilation table). That amending Act inserted s.6A (Crown bound), expanded s.6 to deal with undisclosed property (new subsections (5)-(8)), introduced the interim order power (s.7A), widened eligible applicants to include stepchildren in two categories (new s.7(1)(ea) and (eb)), added the 6-month limit and service requirements for undisclosed-property applications, amended protections for administrators (ss.11, 19, 20), and inserted the detailed hearsay provision s.21A together with the regulation-making power s.21B.

These changes were designed to address practical difficulties: the inability to claim against assets discovered after an order had been made, the lack of urgent interim relief, the exclusion of many stepchildren who had been treated as family, and the unsatisfactory state of the law on admissibility of a deceased person’s statements. The 2011 amendments also aligned the Act with modern family structures by expressly including de facto partners (earlier introduced by the 2002 lesbian and gay law reform legislation) and clarifying illegitimate and artificial-conception relationships.

Earlier amendments had incremental effects. The 1986 Act adjusted time limits. The 2002 Act extended eligibility to same-sex de facto partners. The 2003 Equality of Status amendments updated references to parentage. The 2007 Wills Amendment Act made minor consequential changes. The 2017 Statutes (Minor Amendments) Act corrected cross-references.

Uncommenced provisions in the Evidence Act 2025 and the Assisted Reproductive Technology and Surrogacy Act 2025 will, when proclaimed, further update s.21A and relationship definitions.

The source text contains no decided cases; however, the structure of the Act itself has generated recurring forensic disputes. The central evaluative task under s.6(1)—whether adequate provision has been made for “proper maintenance, support, education or advancement in life”—requires the Court to form an opinion on contested facts. The two-stage process (jurisdictional question then discretionary quantum) has produced satellite litigation about the precise content of the jurisdictional threshold.

The out-of-time leave power (s.7(2)(b) and (3)) has been a frequent battleground. Courts must balance the justice of the case against prejudice to beneficiaries and the public interest in finality of estate administration. Similar contests arise under the parallel leave regime for undisclosed property claims (s.6(7)-(8)).

Section 4(4)’s lifetime-admission-or-establishment rule for parentage has created controversy in cases where a parent dies before a child’s paternity is formally determined. The carve-out for artificial conception (s.4(4a)) was inserted to avoid injustice but has itself required careful forensic proof of the applicable conception pathway.

The protection afforded to administrators (s.20) has been tested where notice is given but the application is not filed within the three-month or twelve-month windows. The precise moment the administrator “becomes entitled to administer” for the purpose of the six-month limit (s.7(2)(a)) has produced interlocutory argument, especially where multiple grants or reseals are involved.

The introduction of stepchild categories in 2011 (s.7(1)(ea) and (eb)) has generated disputes over the meaning of “entitled to be maintained” and the valuation date for the “prescribed amount”. Because the prescribed amount is set by regulation, changes to that figure directly affect eligibility.

Evidentiary controversies under the new s.21A focus on the weight to be given to hearsay statements (s.21A(8)), the circumstances in which credibility evidence may be led (s.21A(9)-(11)), and the Court’s discretion to exclude otherwise admissible statements (s.21A(6)).

The class-fund mechanism (s.13) has been little used but raises questions about trustee discretion versus Court supervision, particularly when one beneficiary seeks to exhaust the fund to the exclusion of others.

Most practitioners assume that once the six-month period in s.7(2)(a) expires the claim is dead; yet s.7(3) expressly permits a motion for leave “at any time” even after expiry. The same latitude applies to undisclosed-property claims (s.6(8)). Many miss that an application by one eligible person can be treated as brought on behalf of all, with limitation consequences for those later served (s.12(2)).

The definition of “stepchild” in s.4(1) is narrower than many expect: the person must have been alive on the date the deceased married or entered the de facto relationship with the parent. A child born after that date to the new partner is not a stepchild for the Act’s purposes.

Section 4(4) can trap claims by grandchildren or more remote descendants where the intermediate parentage link was never admitted or established in the deceased’s lifetime. The artificial-conception exception is easily overlooked.

Administrators frequently distribute after receiving informal notice of a claim. Section 20(5) provides that such notice lapses after three months if the application is not filed (or after 12 months from entitlement to administer). Many administrators do not appreciate that the notice is then “incapable of being renewed” and they may safely distribute.

The power to order a class fund (s.13) is rarely invoked but can be a powerful tool where multiple infant claimants exist; the trustee’s discretion to apply the whole fund to one beneficiary to the exclusion of others is wider than most realise.

Mortgages or assignments of prospective provision are void even if the order is ultimately made in the applicant’s favour (s.19). This trap catches banks and litigation funders who take security before the hearing.

Interim orders under s.7A can include reimbursement for past expenditure incurred after death. This back-dating is often missed in urgent applications.

The rateable burden rule (s.14(2)) does not apply to successive interests in settled property; the whole provision is charged against the corpus (s.14(3)). This can dramatically alter the practical burden on life tenants and remaindermen.

Finally, s.6(5) allows a second bite at the estate where property was undisclosed at the first hearing, but only if its value would have “materially affected” the original order. The evidentiary onus on the applicant to prove both non-disclosure and materiality is heavy, and the additional notice requirements in s.6(6) are easily overlooked.

Compliance for practitioners advising clients begins with a systematic eligibility audit under s.7(1). Gather evidence of the precise relationship, the date of any marriage or de facto relationship, maintenance history, and— for stepchildren—any property passing from the stepchild’s parent to the deceased. For parents and grandchildren, secure admissions or court findings made during the deceased’s lifetime; otherwise the claim is statute-barred by s.4(4).

Advise clients that the six-month clock starts when the administrator becomes entitled to administer in Western Australia, not from the date of death or grant. File promptly or prepare a detailed affidavit explaining delay for a leave application. Where assets may remain hidden, preserve the undisclosed-property route (s.6(5)) by ensuring the first application records the limited information then available.

When acting for administrators, diarise the three-month and twelve-month periods in s.20(5). On receipt of any notice of intended claim, immediately open a file note recording the exact date and content. If the application is not filed within the statutory windows, the notice lapses and distribution may safely proceed. Obtain written consents or waivers from adult beneficiaries under s.20(4) wherever possible; these provide iron-clad protection.

When drafting wills, advise testators that the Court will not assume intestacy rules are adequate (s.6(2)) and that character or conduct may disentitle a claimant (s.6(3)). Consider life insurance, superannuation death benefits or inter vivos trusts outside the estate, but recognise that some of these may still be reachable under associated legislation.

For contested proceedings, prepare for the two-stage inquiry. First, adduce evidence that provision is inadequate; only if the jurisdictional threshold is crossed does the Court move to quantum and the form of order. File supporting affidavits addressing the s.21A admissibility criteria if relying on statements of the deceased. Where multiple claimants exist, consider inviting the Court to create a class fund under s.13 to avoid multiple separate proceedings.

If an order has been made and circumstances later change, assess whether increased provision would be inequitable having regard to “all possible implications” for other persons (s.16(1)). Serve all beneficiaries under any variation application (s.15(2), s.6(6)).

Keep the grant of probate or letters of administration available for immediate production so that any order can be noted (s.14(4)). Where a trustee other than the administrator is to hold a class fund, obtain Court directions under s.13(4) and s.89 of the Trustees Act 1962 at the earliest opportunity.

For corporate or government clients holding estates, ensure compliance with the Crown-binding provision (s.6A) and maintain policies that flag potential family provision exposure before final distribution. Update precedent wills and estate-administration checklists to reflect the 2011 expansions, the prescribed amount for s.7(1)(eb), and the detailed evidentiary regime in s.21A.

In all cases, remember that the Act’s protective philosophy is grounded in “reasonable satisfaction” (s.4(2)-(3)). Evidence must be cogent but need not reach the criminal standard. Compliance therefore requires meticulous factual preparation, timely filing, and a realistic assessment of the strength of the jurisdictional gateway before scarce estate resources are consumed in contested hearings.
