Key Requirements Before Filing
You need to meet California’s residency rules:
- State Residency: One spouse must have lived in California for at least 6 months.
- County Residency: One spouse must have lived in San Mateo County for at least 3 months.
If you tick these boxes, grab your Petition (FL-100) and Summons (FL-110) and file them at the Family Law Clerk’s counter. Yes, that’s it. No magic, no shortcuts – just paperwork and judgment day.
Filing Options
San Mateo County gives you a choice for filing your divorce papers:
- In-Person: Drop off your Petition and other initial forms at the clerk’s counter during office hours.
- E-Filing: Attorneys must e-file, and if you’re representing yourself, you can join the digital fun through an approved e-filing service.
Either way, it’s still paperwork – just with or without a screen.
