What is the document called that contains wishes regarding how one's assets are distributed after death?

The document that contains a person's wishes regarding how their assets are distributed after death is known as a will. A will serves as a legal declaration where an individual details how they want their property and assets to be managed and distributed among beneficiaries upon their passing. It can also appoint executors who will carry out the individual's wishes and manage the estate through the probate process.

In contrast, a trust is generally used to manage assets during a person’s lifetime and can continue distributing those assets after death, but it operates differently from a will. A deed pertains to the legal transfer of property ownership and does not relate to the distribution of assets after death. A contract outlines agreements between parties and is not specifically designed for the posthumous distribution of assets. Therefore, the answer clearly identifies the will as the correct legal document fulfilling this purpose.
