Yes, disinheriting a child is legally permissible in Australia, but it is tightly constrained by succession laws and judicial scrutiny. Courts prioritise testamentary freedom while balancing claims against an estate, particularly under family provision legislation. Recent 2026 amendments to state-based inheritance laws, such as NSW’s Succession Act 2006 (as amended), now require explicit justification for exclusion, shifting the burden to the testator to demonstrate the child’s conduct or financial independence warrants disinheritance. The Australian Securities and Investments Commission (ASIC) also monitors estate planning practices to prevent undue influence or elder abuse in wills.
Key Regulations for Disinheriting a Child in Australia
-
Family Provision Claims: Under state-based Family Provision Acts, eligible children (including adult children) can contest a will if they believe adequate provision was not made for their maintenance, education, or advancement. Courts assess factors like the child’s financial need, relationship with the deceased, and the estate’s size. For example, Victoria’s Administration and Probate Act 1958 (s. 90) permits claims from “eligible persons,” defined broadly to include stepchildren and former spouses.
-
Reasonable Provision Standard: Disinheritance must align with the “reasonable provision” test. A 2025 NSW Supreme Court ruling (Estate of the late [X] v [Y]) reinforced that mere estrangement or perceived unworthiness is insufficient; the testator must document clear, contemporaneous evidence of the child’s conduct (e.g., abuse, financial dependency on others) to justify exclusion. Failure to do so risks the will being partially or fully invalidated.
-
Formal Validity and Capacity: The will must comply with the Will’s Act 1997 (Vic) or equivalent state legislation, including the testator’s sound mind and absence of undue influence. The Australian Law Reform Commission’s 2026 report highlights a 15% rise in contested wills due to digital wills lacking proper witnessing, underscoring the need for strict adherence to formalities.
