On application by the guardian of the estate of a ward or another person interested in the ward's welfare, the court may order that the guardianship of the estate of the ward terminate and be settled and closed if the court finds that the ward no longer needs a guardian of the estate because all of the ward's assets have been placed in an ABLE account established in accordance with the Texas Achieving a Better Life Experience (ABLE) Program under Subchapter J, Chapter 54, Education Code, and the ward is the designated beneficiary of the account.
