Which document specifies who decides the final disposition of a decedent's remains?

The document that specifies who decides the final disposition of a decedent's remains is a Declaration, often referred to as a declaration regarding the disposition of remains or similar terminology in various jurisdictions. This document allows individuals to express their wishes concerning what should happen to their body after death, including details such as burial or cremation preferences and the appointment of someone who will be responsible for carrying out those wishes.

A Last Will and Testament primarily deals with the distribution of the decedent's property and assets after death, which does not directly address the final disposition of remains. Similarly, a Durable Power of Attorney is designed to allow an individual to appoint someone to manage their financial or healthcare decisions while they are alive, and it does not focus on after-death decisions regarding the body.

A Living Trust is used for the management of assets during an individual's lifetime and can also dictate the distribution of property upon death. However, it usually doesn't specify the terms for the final disposition of remains unless explicitly included in the trust provisions, which is not its primary purpose.

In summary, the Declaration is the most relevant and widely recognized document for determining who has the authority to decide the final disposition of a decedent's remains, making it the correct answer in this context.
