Del. Code tit. 10 § 371
All real estate, within this State, shall be liable to be sold, by order of the Court of Chancery, on such terms and in such manner as the Court directs, by the sheriff, or by any party to a civil action in Chancery, when such sale shall be necessary to give effect to, and carry into execution a judgment of the Court of Chancery. When any such real estate is so sold, and there is a surplus of money, arising from the sale, above, what is sufficient for the purposes of the sale, such surplus shall be paid over, or applied, as the Court orders. Such sales shall be as available in law to the vendees, as sales of land seized and sold upon judgment and execution are available by virtue of any law in this State. If any such judgment, under which any real estate is so sold, is reversed by the Supreme Court, none of the real estate, so sold, shall be restored, nor shall the sale thereof be avoided, but restitution shall be made, in such cases, of the money for which such real estate was sold. No sale shall be valid until return thereof is made to the Court of Chancery, and it is approved and confirmed by the Court.
