Tenn. Code § 34-5-119
In addition to any other provisions of law relating to judicial restoration and discharge of guardian, a certificate by the veterans administration showing that a minor ward has attained majority, or that an incompetent ward has been rated competent by the veterans administration upon examination in accordance with law, shall be prima facie evidence that the ward has attained majority, or has recovered competency. Upon hearing after notice as provided by this chapter and the determination by the court that the ward has attained majority or has recovered competency, an order shall be entered to that effect, and the guardian shall file a final account. Upon hearing after notice to the former ward and to the veterans administration as in case of other accounts, upon approval of the final account, and upon delivery to the ward of the assets due the ward from the guardian, the guardian shall be discharged and the guardian's sureties released.
