Mississippi Code Title 93. Domestic Relations § 93-16-3

(1) Whenever a court of this state enters a decree or order awarding custody of a minor child to one (1) of the parents of the child or terminating the parental rights of one (1) of the parents of a minor child, or whenever one (1) of the parents of a minor child dies, either parent of the child's parents may petition the court in which the decree or order was rendered or, in the case of the death of a parent, petition the chancery court in the county in which the child resides, and seek visitation rights with the child.

(2) Any grandparent who is not authorized to petition for visitation rights pursuant to subsection (1) of this section may petition the chancery court and seek visitation rights with his or her grandchild, and the court may grant visitation rights to the grandparent, provided the court finds:

(3) For purposes of subsection (2) of this section, the term “viable relationship” means a relationship in which the grandparents or either of them have voluntarily and in good faith supported the child financially in whole or in part for a period of not less than six (6) months before filing any petition for visitation rights with the child, the grandparents have had frequent visitation including occasional overnight visitation with said child for a period of not less than one (1) year, or the child has been cared for by the grandparents or either of them over a significant period of time during the time the parent has been in jail or on military duty that necessitates the absence of the parent from the home.

(4) Any petition for visitation rights under subsection (2) of this section shall be filed in the county where an order of custody as to the child has previously been entered. If no custody order has been entered, then the grandparents' petition shall be filed in the county where the child resides or may be found. Upon a showing of financial hardship for the parents, the court shall on motion of the parent or parents direct the grandparents to pay reasonable attorney's fees to the parent or parents at any time, including before a hearing, without regard to the outcome of the petition.
