Miss. Code Ann. § 93-7-7

When an annulment shall be adjudged or a marriage declared void, the chancery court may, in its discretion, having regard to the circumstances of the parties and the nature of the case, as may seem equitable and just, make all orders touching the care, custody, and maintenance of the children of the marriage; and the court may, afterwards, on complaint, change the judgment and make from time to time such new judgment as the case may require.
