Noncustodial Parent

Child Support Program services are for both parents—custodial parties and noncustodial parents (NCPs). NCPs can apply for services or ask to modify child support already ordered. Local child support agencies are an important resource for NCPs. By working closely with the local agency, NCPs can avoid or minimize issues that may arise regarding their child support case and/or child support payments.

Applications for service are available at the local office or may be downloaded from our websiteCompleted applications must be mailed or dropped off at the local child support agency office to be processed.

Under California law, NCPs are required to pay their court-ordered child support on time and in full. If you cannot meet the full obligation or cannot make the court-ordered payments contact the local child support agency as soon as possible to avoid or minimize any adverse actions that may be taken. Unpaid child support will still be owed—with interest.

Passport Rules

Beginning June 1, 2009, U.S. citizens who wish to travel to Mexico, Canada, the Caribbean or Bermuda will need a passport. Parents who have a case with their local child support agency and who owe more than $2,500 in past due child support, will be denied issuance or renewal of a passport due to federal child support statutes that have been in effect since 1996.

To avoid denial of a passport application or renewal of an existing passport for the purposes of exiting the country, parents who owe more than $2,500 in past due child support should take steps to pay all past due child support as soon as possible. To reach your local child support office, call the statewide toll free number at 1‑866‑901‑3212 for assistance.
