A 70-year-old man with early-stage dementia writes a new will disinheriting his children and leaving his entire estate to his live-in caretaker. The family contests the will in court. Under the Banks v Goodfellow criteria, which of the following is essential for the will to be considered valid?
- A He must be able to recall the exact monetary value of every asset he owns.
- B He must have a formal psychiatric declaration of competency signed within the last month.
- C He must understand the nature of making a will and the claims of beneficiaries, with no delusion altering his disposition. ✓
- D He must be able to explain the legal terminology of testamentary succession.
Correct answer: C. He must understand the nature of making a will and the claims of beneficiaries, with no delusion altering his disposition.
Explanation
Testamentary capacity, as defined in the Banks v Goodfellow criteria, requires the testator to understand the nature of making a will, the extent of their property, and the claims of potential beneficiaries, ensuring no delusion alters the disposition. Exact recall of every asset value is not required; understanding the general extent of the estate suffices. A formal psychiatric declaration of competency is not a prerequisite for the will's validity.
