What type of legal document states the wishes of a person regarding their estate after death?

The correct answer, the last will and testament, is a legal document that specifically outlines how a person's estate, assets, and property should be distributed after their death. This document allows individuals to convey their wishes regarding who will receive their belongings, who will manage their estate, and any specific instructions they wish to include, such as the care of minor children.

A power of attorney, in contrast, is a document that grants another person the authority to act on one's behalf while they are still alive, typically for managing financial or legal matters.

A trust agreement involves the establishment of a trust, which can manage assets during a person's life and distribute them after their death, but it serves a broader purpose than just specifying wishes after death.

A living will primarily addresses medical care preferences while an individual is still alive, particularly regarding end-of-life decisions, rather than estate distribution after death. Thus, while all these documents relate to personal wishes and legal matters, the last will and testament is uniquely focused on the distribution of an estate posthumously.
