Where to File Your Paperwork in Sonoma County?
To start your divorce in Sonoma County, you must file your paperwork with the Superior Court of California, County of Sonoma. Yeah, that simple. While your case will ultimately be handled by the Family Law division (though you might have some specific hearings there), all initial legal documents must be processed through the Clerk’s Office.
As of January 1, 2026, Sonoma County has implemented mandatory e-filing for all parties represented by an attorney or document preparer. If you are representing yourself, you may still file in person or via the court’s drop box.
Address: 3055 Cleveland Avenue, Santa Rosa, CA 95403
Phone: (707) 521-6500
Business Hours: Monday–Friday, 8:00 a.m. – 3:30 p.m.
Where to File: Submit your documents at the Family Law Clerk’s Office at the Cleveland Avenue address. There is also a 24-hour drop box located at the main entrance for after-hours filing.

Divorce Requirements: Do You Qualify?
To file for divorce in Sonoma County, you must meet California’s residency requirements. At least one spouse must have lived in:
- California for the last six months.
- Sonoma County for the last three months before filing.
Using an online service simplifies this process by ensuring your documents meet specific California codes and Sonoma County Local Rules, preventing common filing errors that can lead to court rejection.

Filing for an Uncontested Divorce (When Both Spouses Agree)
An uncontested divorce and a Joint Petition for Dissolution are basically the same thing, making them the most efficient way to end a marriage in California. Under the new 2026 California Senate Bill 1427, couples who agree on all terms can now file using this method. On the other hand, this streamlined process is available even for couples with children or significant assets, provided there is total agreement.
The process follows these key steps:
- File the Petition: You file either a standard Petition (FL-100) or the new Joint Petition. The standard filing fee in Sonoma County is $435.
- Service of Process: In a standard divorce, you must “serve” your spouse. However, if you file a Joint Petition, service is considered automatic at the time of filing, skipping the need for a process server.
- Financial Disclosures: Both spouses must exchange “Preliminary Declarations of Disclosure.” This is a mandatory step where you list all assets, debts, income, and expenses.
- The 6-Month Waiting Period: California law requires a mandatory waiting period of six months and one day from the date of service (or joint filing) before the judge can sign the final decree.
- The Written Agreement: During the waiting period, you will finalize your Stipulated Judgment. This contract outlines how you will divide property, handle child custody, and determine support.
- Final Decree: Once the waiting period ends and your agreement is submitted, the judge signs the Judgment of Dissolution. In most uncontested cases, you will never have to step into a courtroom.
Our service helps you navigate the six-month “cooling off” period by ensuring your settlement agreement is drafted and signed early, so your divorce is finalized the moment the legal clock runs out.

Common Sonoma County Divorce Forms You Will Need
California uses standardized “FL” (Family Law) forms. To complete your divorce in Sonoma County, you will generally need:
- FL-100 (Petition): The document that starts the case.
- FL-110 (Summons): Notifies your spouse of the case and includes temporary restraining orders regarding property and insurance.
- FL-105 (UCCJEA): Required if you have minor children to establish the court’s jurisdiction over them.
- FL-141 (Proof of Service of Disclosure): Tells the court you have shared your financial info with your spouse.
- FL-130 (Appearance, Stipulations, and Waivers): Used in uncontested cases to show both parties are participating without a fight.
- FL-180 (Judgment): The final document the judge signs to end the marriage.
Note: If you are seeking a fee waiver due to low income, you must also file forms FW-001 and FW-003.

Divorce Filing Fees and Costs
As of 2026, the standard fee to file a divorce petition in Sonoma County is $435. If the respondent (the other spouse) files a formal “Response,” they must also pay a $435 filing fee.
However, under the 2026 Joint Petition rules, couples filing together may be eligible for a combined or streamlined fee structure. If you cannot afford these costs, you can file a Request to Waive Court Fees. If approved, the court will waive the filing fees and certain other court costs entirely.
