A plain-language guide to divorce in Contra Costa County, from the forms you file at the Superior Court of California, County of Contra Costa to costs, timeline, and how to prepare your paperwork without hiring an attorney.
Contra Costa County sits in the East Bay portion of the Bay Area and is one of the region's larger and more populous counties, stretching from the shoreline communities near San Francisco and San Pablo Bay out to fast growing suburban centers further inland. If you live or were married in the county, you file your divorce with the Superior Court of California, County of Contra Costa, based in the county seat of Martinez.
Contra Costa is a mix of dense suburban cities, established commuter towns, and newer residential growth, which means the court handles a steady, substantial volume of family law matters each year. Because the county covers a wide geographic area, it maintains more than one courthouse location, and which one is correct for your case can depend on where you live. Confirming the right location before you file is a practical first step that can save you a wasted trip.
Whatever your address in the county, the underlying legal process is identical to every other county in California. You complete the same Judicial Council forms, observe the same mandatory waiting period after your spouse is served, and provide the same financial disclosures whether you file in Contra Costa County or anywhere else in the state. Divorce law in California does not change from courthouse to courthouse.
What does vary locally are the practical details: which specific courthouse handles your case type, current hours of operation, and whether a given filing can be submitted electronically. Those details can change over time, so before you file anything, confirm the current courthouse, address, and procedures using the official California Courts court finder rather than relying on older information you may have found elsewhere.
Divorce cases in Contra Costa County are handled by the Superior Court of California, County of Contra Costa, with the county seat in Martinez. Because courthouse locations, hours, filing fees, and electronic filing options change over time and can differ between branches, use the official California Courts court finder to confirm the current address and filing details for your case:

California uses the same statewide Judicial Council forms in every county, including Contra Costa County. The core steps are:
The court filing fee to open a case is generally $435 to $450 depending on the county, and a fee waiver (Form FW-001) is available if you cannot afford it. No California divorce can be finalized in less than six months from the date of service, and that waiting period applies in Contra Costa County like everywhere else in the state.
Because Contra Costa County covers a wide stretch of the East Bay and has more than one courthouse location, do not assume the branch nearest you automatically handles family law matters. Use the official California Courts court finder to confirm which location is correct for a case at your address before you show up to file.
Like most California counties, Contra Costa offers self-help resources for people who are representing themselves in a divorce, though staff there can only point you to information and forms, not give you legal advice. Filing your paperwork completely and correctly the first time is the best way to keep your case moving and avoid extra trips back to the courthouse.
If your situation involves domestic violence, a business or other complex assets, or a contested custody dispute, it is worth consulting a licensed California family law attorney rather than proceeding entirely on your own, since those cases carry stakes a self-help center cannot advise you on.
You file with the Superior Court of California, County of Contra Costa, headquartered in Martinez, the county seat. The county has more than one courthouse location, so use the official California Courts court finder to confirm which one handles family law filings for your address before you go.
