Del. Code tit. 25, § 106

Any deed executed and acknowledged by a trustee for a married man or woman with a mental disability, appointed pursuant to the provisions of § 104 or § 105 of this title, shall be as valid and effectual to bar and divest the right of dower or curtesy of the spouse with a mental disability, in case the spouse with a mental disability survives, as if such spouse with a mental disability had been legally capable and had in fact executed and acknowledged such deed. Any such deed, or the record thereof, shall be competent evidence in all the courts of this State.
