Parties must pay filing fees to the clerk of the court at the time the parties file papers with the court.
The amount of money required to pay filing fees in family court is established by the Uniform Civil Fees and Standard Fee Schedule Act of 2005 under Government Code section 70670 et seq. and is subject to change. The act covers fees the court may charge parties to file the first papers in a family law proceeding, motions, or other papers requiring a hearing. It also covers filing fees that courts may charge in proceedings relating to child custody or visitation (parenting time) to cover the costs of maintaining mediation services under Family Code section 3160 et seq.
