Mississippi Code Title 93. Domestic Relations § 93-9-17

(1) An action under Sections 93-9-1 through 93-9-49 may be brought in the county where the alleged father is present or has property; or in the county where the mother resides; or in the county where the child resides. However, if the alleged father resides or is domiciled in this state, upon the motion of the alleged father filed within thirty (30) days after the date the action is served upon him, the action shall be removed to the county where the alleged father resides or is domiciled. If no such motion is filed by the alleged father within thirty (30) days after the action is served upon him, the court shall hear the action in the county in which the action was brought.

(2) Subsequent to an initial filing in an appropriate court, any action regarding paternity, support, enforcement or modification and to which the Department of Human Services is a party may be heard in any county by a court which would otherwise have jurisdiction and is a proper venue. Upon written request by the Department of Human Services, the clerk of the court of the original county shall transfer a certified copy of the court file to the clerk of the appropriate transfer county without need for application to the court. Such written request shall certify that the Department of Human Services has issued timely notification of the transfer in writing to all interested parties. Such written request and notice shall be entered into the court file by the transferring clerk of the transferring court. The transferred action shall remain on the docket of the transferred court in which the action is heard, subject to another such transfer.
