(a) The court may award to either party the costs and counsel fees that are just and proper under all the circumstances in any case in which a person:

(1) applies for a decree or modification of a decree concerning the custody, support, or visitation of a child of the parties; or

(2) files any form of proceeding:

(i) to recover arrearages of child support;

(ii) to enforce a decree of child support; or

(iii) to enforce a decree of custody or visitation.

(b) Before a court may award costs and counsel fees under this section, the court shall consider:

(1) the financial status of each party;

(2) the needs of each party; and

(3) whether there was substantial justification for bringing, maintaining, or defending the proceeding.

(c) Upon a finding by the court that there was an absence of substantial justification of a party for prosecuting or defending the proceeding, and absent a finding by the court of good cause to the contrary, the court shall award to the other party costs and counsel fees.
