To establish paternity, get a support order or enforce a support order, the San Mateo County DCSS must know where the obligor parent lives and/or works. By providing the San Mateo County DCSS with as much information as possible, the custodial party can help locate the obligor parent and speed up the child support process.  See the section titled "Open a Case" for a list of the information needed by the San Mateo County DCSS to assist in locating the obligor parent.

If the obligor parent cannot be found locally, his/her Social Security number will be checked against the records of other state agencies including the Department of Health Services, Department of Motor Vehicles, Social Security Administration, Employment Development Department, Franchise Tax Board, Board of Equalization, credit reporting agencies and law enforcement agencies.  If the search reveals that the parent has moved to another state, the other state and the Federal Parent Locator Service will be asked to search for the parent.  Attempts will be made regularly to locate the obligor parent as required by both state and federal regulations.

The custodial parent can submit locate information for the obligor parent via Customer Connect

Once the San Mateo County DCSS has obtained a current address for the obligor parent, they will verify the address and begin taking legal action.  Also, the obligor parent may be contacted to come to the office for an interview and to advise that legal action is being or may be taken.
