判决理由
Testamentary capacity requires that the testator understands the nature of making a will, the extent of property being disposed of, the claims of persons who might expect to benefit, and is not affected by any disorder of the mind.
事实
John Banks made a will leaving his estate to his niece. His relatives challenged the will, arguing he lacked testamentary capacity due to delusions.
判决摘要
The court upheld the will. Despite suffering from delusions, they did not affect his testamentary dispositions. The court established the classic test for testamentary capacity.
