Which document empowers an executor to manage the estate of the deceased?

The document that empowers an executor to manage the estate of the deceased is known as Letters Testamentary. This legal document is issued by a probate court and grants the executor the authority to act on behalf of the deceased person’s estate. It typically includes the power to collect assets, pay debts, and distribute the estate according to the wishes outlined in the deceased’s will.

Letters Testamentary are specifically associated with estates that have a valid will and where the executor has been named by that will. This document serves as proof of the executor's authority and is essential for any interactions with financial institutions, tax agencies, and property registries regarding the deceased's estate.

In contrast, Letters of Administration would apply when there is no will, and an administrator is appointed. A Grant of Authority is not a standard term used in the context of estate management and may not reflect a specific legal document. Executor's Consent is not an official document issued by the court but may refer to various consents or agreements made by an executor during the administration process. Hence, Letters Testamentary is the correct answer as it directly relates to the empowerment of an executor to manage and administer the estate of the deceased according to the terms set forth in the will.
