Plain-English meaning

Testamentary Capacity

The level of mental capacity required to make a valid will under applicable law.

Why the term matters

Capacity disputes focus on the signer at the time of execution and can depend on witnesses, medical context, drafting records, and surrounding conduct.

Do not confuse it with

A diagnosis, advanced age, or later incapacity does not automatically establish that the person lacked testamentary capacity when the will was signed.
