Drafting and revision of instruments. For new legal instruments, draftsmen should use explicit numerical ages where they intend a specific threshold rather than general terms such as “minor” or “full age.” Section 5(3) preserves references to an age expressed in years, whereas the Act reinterprets general expressions to align with section 4 (s 5(2)-(3)). To avoid unintended operation of the default interpretive rule, expressly state the intended age threshold and, if different from 18, provide a clear contrary intention.
Review existing post-commencement documents. Organisations, businesses and legal practitioners should audit instruments made after commencement that use terms such as majority, minor or infant and decide whether the redefinition to 18 (s 5(2)) matches transactional intentions. Where it does not, revise those instruments to specify the intended age numerically or add clarifying provisions that manifest a contrary intention.
Wills and codicils practice. For wills executed before commencement, note that s 6(1) preserves their construction. Codicils executed after commencement to pre-commencement wills are, absent contrary intention, to be construed as if the Act had not been made (s 6(2)). Executors, testators and advisers should ensure that any codicil expressly states whether it is intended to operate under pre‑commencement or post‑commencement rules, and consider executing a new will where coherent modernisation is intended.
Estate administration and intestacy. Administrators dealing with estates where the deceased died before the date of commencement must apply s 7: the Act does not, by itself, compel distribution to beneficiaries under 21. Administrators should confirm dates (date of death and the Act’s commencement notice), apply the intestacy rules in force at the relevant time, and seek directions or judicial guidance where needed before making distributions. Where funds are being held for minors under court orders, trustees should check s 8 to see whether the order in force immediately before commencement is affected by the conversion of 21 to 18.
Court-ordered funds and trusteeship. Trustees tasked with holding funds under pre-commencement court orders should inspect the order to see whether it contains references to attainment of a particular age. Under s 8, such references to 21 become references to 18. Trustees should consider whether variation applications are necessary if the order’s terms are inconsistent with the current needs of beneficiaries, and they should obtain professional advice if there is ambiguity.
Employment and industrial relations compliance. The Act leaves industrial awards and agreements and contracts of employment unaffected (s 13(2)-(3)). Employers and unions should therefore not assume they can change award-based entitlements merely because the statutory age of majority has changed. Any changes to employment rights must be consistent with awards, agreements and contracts, and parties should consult industrial relations instruments to determine whether explicit ages are used there.
Organisational policies and operational procedures. Entities that maintain age-based operational rules (for example, credit-granting policies, tenancy criteria, insurance underwriting, or consent procedures) should review their policies to confirm whether they depend on “minor” as a concept or a specific numeric age. If a policy assumed lack of capacity until 21 but relied on the general term “minor,” it likely now operates with 18 as the threshold unless the policy expressly stated otherwise. Organisations should update policy language or include express age thresholds to ensure alignment with the Act’s interpretive rules.
Records and administrative timing (ss 2-3, s 4(3)). Because the Administrator fixes the commencement date by Gazette notice (ss 2-3), compliance requires noting that date precisely. Parties acting around the commencement window should record relevant dates: a person’s date of birth, the date of the Gazette notice and the date of death in intestacy cases. Section 4(3) specifically affects persons who on commencement had reached 18 but not 21; administrators and advisers must confirm whether a person falls into this transitional class.
Seek judicial or professional guidance where ambiguous. Where instruments are ambiguous as to whether a “contrary intention” exists (s 5(2), s 6(2)), or where administrators worry about potential exposure in changing distributions (s 7) or in dealing with court orders (s 8), practitioners should consider seeking declaratory relief or directions from a court or tribunal rather than acting solely on a private interpretation. The Act creates changed legal meanings but does not supply adjudicative mechanisms; courts remain the venue for clarifying ambiguous “contrary intentions” and resolving contested distributions.
Document intended intent in revisions and new instruments. To reduce future disputes, documents amended after commencement should set out an express statement of intent on age thresholds and capacity,either embracing the statutory 18-year rule or expressly preserving a different numerical age where permitted. For testamentary or settlement planning, consider re-executing documents where clarity is essential.
In short, compliance consists of auditing and revising post-commencement instruments, using explicit numerical ages where needed, confirming commencement-related dates in transitional matters, and obtaining professional or judicial guidance for ambiguous or high-risk scenarios. All changes should account for the Act’s savings in s 13 and the preservation of pre-commencement dispositions in s 5(4).
