Letters Testamentary and Evidence of Estate Authority

Letters testamentary are court-issued evidence that a named executor has been appointed and is authorized to act for a probate estate. When there is no will or no qualifying executor, many states issue letters of administration or a similarly named document.

A will nomination alone does not necessarily confer authority before court appointment. The petition, notice, qualification, oath, bond, and issuance procedures vary by state and estate type.

Financial institutions, title companies, taxing authorities, and other parties may request a recently certified copy, death certificate, tax identification number, affidavit, or institution-specific form. The number and recency of copies needed depend on the assets and recipient; no fixed quantity works for every estate.

Letters do not authorize action beyond state law, the will, and court orders. Restrictions, supervised administration, later suspension, resignation, removal, or estate closure can affect authority.
