Upon every divorce, and upon every divorce from bed and board for any cause, if any real and personal estate of either party, or money in lieu of the real or personal estate is awarded to either party as provided in section 19, the court, instead of ordering it to be delivered or paid to either party, may order it to be delivered or paid to a trustee or trustees, to be appointed by the court, upon trust to invest it, and to apply the income from it to the support and maintenance of either party, and of the children of the marriage, or any of them, in the manner as the court shall direct.
