The service fee is $3.50 per month in addition to the Payer’s (person who pays child support) assessed child support. For example, if child support is calculated at $250.00 per month, the Payer actually pays $253.50 per month. This $3.50 is not received by the Payee (person who receives child support); this service fee is assessed to reimburse the Friend of the Court for its services.
