TESTAMENTARY

Relating to wills.

An individual is said to have testamentary capacity to make a will when that person has sufficient mental ability to comprehend what he or she is doing, the nature and extent of his or her property, the natural objects (which means appropriate persons or recipients) of his or her bounty, and the interrelationships among these three concepts.
