Background

Norma Joan Odlum died in August 2024 aged 97, survived by four children. Her 2018 will, as amended by a 2020 codicil, made minor specific gifts, forgave loans owed by her children, and divided the residue equally among them through testamentary trusts. Anthony Odlum and Catherine Lorraine Garner, two of the children and the named executors, sought probate in solemn form.

Judith Anne Odlum lodged caveats opposing the grant, alleging that the deceased lacked testamentary capacity. Judith’s defence and cross-claim were struck out before the hearing, but the Court still had to be satisfied that the deceased had capacity and knew and approved the will and codicil. After probate was granted in May 2026, Judith sought to raise broader accounting and administration complaints.

The Court’s Holding

Slattery J granted probate of the 2018 will and 2020 codicil to Anthony and Catherine in solemn form and struck out Judith’s caveat. The Court accepted detailed evidence from the solicitors who took instructions and witnessed execution, as well as evidence that the instruments rationally reflected the deceased’s consistent wish to benefit all four children equally.

Although the deceased had Alzheimer’s disease and vascular dementia, neuropsychological evidence supported her capacity at the relevant time. She understood the general operation of her will, her principal assets, and that her children were the intended beneficiaries; she consistently wished to forgive their loans and divide the estate equally. The Court dismissed the remaining proceedings, holding that any unresolved administration issues should be pursued separately. The plaintiffs’ costs were payable from the estate on an indemnity basis.

Key Takeaways

  • Dementia does not itself prevent a finding of testamentary capacity where the evidence establishes capacity when the instrument was executed.
  • Contemporaneous solicitor evidence of instructions and execution can strongly support capacity and knowledge and approval.
  • Probate proceedings are not the appropriate vehicle for wide-ranging disputes about later estate administration.

Why It Matters

The decision illustrates the Court’s focus on the testator’s actual understanding and intentions at the time of execution, rather than a diagnosis alone. It also confirms that a caveator’s unsupported objections will not displace regular execution and persuasive professional and expert evidence.

For estate litigators, the case distinguishes a challenge to the validity of testamentary instruments from disputes that must instead be resolved through administration proceedings.
