If want of assets to pay debts and devises is pleaded in the action and if the account of the personal representative has not been settled, the court shall require him to account. Judgment shall be entered and execution shall issue only for the proportion ascertained to be payable to plaintiff, but the judgment shall remain a security for the payment of the residue of the devise and costs out of assets which may thereafter come to the possession of the personal representative.
