(a) Whenever the department receives an application for public assistance on behalf of a child and it appears that the child has been abandoned by one or both parents or that the responsible parent has failed to provide support to the child, it is the department's responsibility to take appropriate action under this article, the child support statutes, or other appropriate state and federal statutes to assure that the responsible parent supports the child.

(b) The department shall accept applications for child support enforcement services from a custodian of a minor child who is not a recipient of public assistance and shall take appropriate action under this article, the child support statutes, or other state and federal statutes to assure that the responsible parent supports the child. The department shall provide that a reasonable application fee be charged each individual who applies for services under this subsection. The department shall enforce an order for alimony so long as child support is being collected along with alimony and all provisions of subsection (d) of Code Section 19-11-6 are met.

(c) Any action initiated by the department pursuant to subsection (b) of this Code section or in any action in which the department appears pursuant to subsection (b) of this Code section shall be limited solely to the issue of support and shall exclude issues of visitation, custody, property settlement, or other similar matters otherwise joinable by the parties.
