If, at the time any dividend is made, there shall be a contingent or unliquidated claim against the debtor or an outstanding bond, recognizance or undertaking upon which the debtor shall have been principal, surety or indemnitor, the trustees must retain in their hands for such period or periods as the court having jurisdiction of the matter may by order direct a sum of money sufficient to pay a due or equal proportion of said dividend upon such contingent or unliquidated claim or liability if and when the same shall be established and liquidated.
