What document allows an individual to dictate the management of their assets after death?

The correct choice is a will, as it is a legal document that outlines how a person's assets will be distributed after they pass away. A will allows individuals to specify beneficiaries for their property, appoint an executor to manage the process of settling their estate, and include any specific wishes they have regarding the handling of their affairs after death. This is a fundamental tool in estate planning that ensures that one's assets are managed and transferred according to their wishes rather than the default laws of intestacy, which may not align with the deceased's preferences.

In contrast, a trust is a legal arrangement that can manage assets during a person's lifetime and after death, but it requires a different level of legal work and is not specifically solely about distribution after death as a will is. A power of attorney is used to appoint someone to manage financial or legal decisions on behalf of another individual, typically during their lifetime, and does not apply after death. A living will, while important in defining medical wishes, specifically addresses healthcare decisions and does not involve the distribution of assets.
