Where the court has power to direct any property to be settled, or to vary the terms of an existing settlement, it may appoint trustees to whom the money shall be paid, and may order the necessary instruments to be prepared containing such provisions as it may think fit, and may order all necessary parties to execute the instruments, and may from time to time appoint new trustees, and may do all such other acts as it may deem necessary for carrying such directions into effect. 29. Custody of children. In suits for dissolution of marriage, or for nullity of marriage or for judicial separation, the court may at any stage of the proceedings, or after a decree absolute has been pronounced, make such order as it thinks fit, and may from time to time vary or discharge the orders, with respect to the custody, maintenance and education of the minor children of the marriage, or for placing them under the protection of the court. 30.
