Welcome to the San Mateo County Department of Child Support Services

We wish to help you during this difficult and emotional time.  Please allow us to assist you in understanding the child support process.  Children need two involved parents, and we hope that the child support program will serve the families who need it well.  Both parents are legally required to shoulder the responsiblity of helping their children grow and develop into adulthood.

We will work with both parents to provide respectful, effective, and efficient services.  We will demonstrate our care and commitment as we engage with you to establish a child support order that is fair and allows for consistent payments to children, so they will have a better chance to succeed in the world.

Please take some time to review the information provided. If you have any questions about either your case or the child support process, please contact our office. You can send us email through our website or call our Customer Service Center toll free at (866) 901-3212 between the hours of 8:00 a.m. to 4:45 p.m.  You are also welcome to visit our office in Redwood City. Our caseworkers meet with visitors during office hours, which are Monday through Friday, 7:30 am to 5:00 pm. If you come into the office, we will try to see you right away, but we guarantee that your wait will be no longer than 20 minutes.

I hope that the information available on this website will help you learn more about our department and the child support process. We look forward to working in partnership with you on your child support case.
