A. An action to make past due child support executory may be filed by any plaintiff, who is unable to utilize the provisions of Chapter 5 of Title I of Book IX of the Code of Civil Procedure, without paying the costs of court in advance or as they accrue or furnishing security therefor, if the court is satisfied that the plaintiff because of poverty or lack of means cannot afford to make payment.
B. When the action has been filed without the payment of costs as provided in Subsection A and the plaintiff is not the prevailing party, except for good cause, the court shall order the plaintiff to pay all costs of court.
