Texas Property Code - PROP § 74.3061. Escheat of Funds in the Possession of the United States

(a) In the event any money is due to a resident of this state in the nature of a refund, rebate, or other overpayment of taxes or fees to the United States with respect to which the resident is likely to have his rights to secure such refund or rebate barred by a statute of limitations, or if for any reason at least three years has elapsed after the date on which the resident could have filed a timely claim for said refund or rebate, the comptroller is appointed agent of such resident to apply for said refund or rebate and is authorized to do any act which a natural person could do to recover said money. When the comptroller files an application or initiates any other proceeding to secure said refund or rebate, the comptroller is coupled with an interest in the money sought and money recovered. All property within this provision, including all principal and interest accruing thereon, is declared to have escheated and to have become the property of the state.

(b) The funds escheated by the state pursuant to this provision shall be given notice as provided by Section 74.201. Title to any such property shall be transferred by the state to any persons who in accordance with Subchapter F can show that the property belonged to them immediately prior to the escheat or that they were heirs to those funds immediately prior to the escheat.
