Pertaining to or relating to a will or testament. Used to describe documents, dispositions, trusts, or other arrangements that take effect upon death rather than during the maker's lifetime. Also refers to matters governed by will law and formalities.
Testamentary simply means "related to a will" or "happening at death." When lawyers say something is testamentary, they mean it's connected to your will or only takes effect when you die, not during your lifetime.
