Tennessee Code Title 62. Professions, Businesses and Trades § 62-5-707

Any person signing a funeral service agreement, cremation authorization form, or any other authorization for disposition shall be deemed to warrant the truthfulness of any facts set forth therein, including the identity of the decedent whose remains are to be buried, cremated, or otherwise disposed of, and the party's authority to order such disposition. A funeral establishment shall have the right to rely on such funeral service contract or authorization and shall have the authority to carry out the instructions of the person whom the funeral establishment reasonably believes holds the right of disposition. No funeral establishment is responsible for contacting or independently investigating the existence of any next-of-kin or relative of the decedent.
