What is the term for a person who accepts the terms of a will?

The term for a person who accepts the terms of a will is "beneficiary." A beneficiary is someone designated in a will to receive a portion of the deceased person's estate. This individual has a legal right to inherit the specified assets, and their acceptance of these terms typically implies that they agree to the conditions laid out in the will.

In contrast, a testator is the person who creates and executes a will, outlining how their estate should be distributed upon their death. A codicil is a legal document that modifies or adds to an existing will, while a legatee specifically refers to someone who receives a legacy, which is typically a gift of personal property bequeathed in a will. While all these terms are related to the context of wills and estates, the primary definition pertaining to the acceptance of the terms of a will is that of a beneficiary.
