When assessing testamentary capacity of elderly testators who have delegated financial management to family members, the court should look to the testator's capacity to understand the nature and extent of their assets, not their actual knowledge of precise financial details. An inability to recall the precise extent of assets does not negate capacity where the will's provisions are relatively straightforward and the testator understands the bulk of the estate passes through the residuary clause. The involvement of beneficiaries in arranging for a will to be prepared gives rise to a suspicion requiring vigilant examination under the knowledge and approval doctrine, but that suspicion can be allayed by evidence that an independent solicitor took instructions directly from the testator.
