Courthouses Handling Family Law
How to Submit Your Divorce Papers in Sonoma
- In person
- Bring the original plus two copies of each document to the Family Law & Probate Clerk's Office at 3055 Cleveland Ave (clerk hours 8:00 a.m.–3:30 p.m.). The court says this is the best option for self-represented parties because rejected papers can be fixed on the spot.
- By mail
- Mail to Family Law & Probate Clerk's Office, Civil & Family Law Courthouse, 3055 Cleveland Avenue, Santa Rosa, CA 95403, with the original plus two copies, fee payment, and a self-addressed stamped envelope — without the envelope your copies are not returned.
- Drop box
- Put documents in a large envelope (no loose papers) in the drop box mounted on the wall left of the courthouse entrance, with the original plus two copies, payment, and a self-addressed stamped envelope for your conformed copies.
- E-filing
- Self-represented parties may e-file through the court's e-filing portal (Odyssey eFileCA) 24 hours a day; documents received by 11:59 p.m. on a court day are filed that day. Court staff do not give e-filing tech support; an e-filing voicemail line is (707) 521-1050.
E-Filing in Sonoma
The Sonoma County Superior Court accepts electronic filing (e-filing) for family law cases through approved Electronic Filing Service Providers (EFSPs). If you are representing yourself, e-filing is optional — you can still file on paper.
Under Local Rule 17.22, represented parties must e-file in all family law matters; self-represented parties are exempt from mandatory e-filing but may e-file. E-filing fees are waived for filers who show inability to pay court fees.

Filing together in Sonoma?
If you and your spouse both want the divorce, California's Joint Petition (SB 1427) lets you file as co-petitioners — no process server, and no one has to be “served.” See how the California Joint Petition works.
How Much Does Divorce Cost in Sonoma?

|---|---|
| Court filing fee — Petition (FL-100) | $435 |

Joint petition: $435 or $870 in Sonoma?
$870 — and that is the total for your case, not per spouse. A joint petition (FL-700) for dissolution or legal separation filed with the Sonoma County Superior Court carries one combined $870 fee that covers both spouses' appearances, in place of the separate Petition and Response fees in a traditional filing. If one spouse later revokes the joint petition, the schedule says no additional first-appearance fee is due from either of you. The $435 figure applies only to a joint petition for summary dissolution, a separate short-marriage procedure with strict eligibility limits. Fee waivers are available for those who qualify.

Fee waivers in Sonoma
The court says you can apply for a fee waiver at the same time you file your documents, in person, by drop box or by mail. Sonoma posts a fee-waiver forms page (FW-001, FW-003, FW-015-INFO), and e-filing provider fees are waived for filers with demonstrated inability to pay. Sonoma court fee-waiver information.

What to Expect After Filing in Sonoma
- ✓Family law moved out of the Hall of Justice: dissolution filings, the family law clerk and the Family Law Facilitator are now at the Civil and Family Law Courthouse, 3055 Cleveland Ave, Santa Rosa.
- ✓Local Rule 17.22 requires attorneys and represented parties to e-file in family law cases; self-represented parties are exempt and can still file on paper.
- ✓The clerk asks paper filers to paperclip (not staple) originals because they are scanned, and to staple only the copies, each original placed on top of its copies (e.g., FL-100, FL-105, FL-110 sets).
- ✓Sonoma family law case numbers begin with 'SFL'; when searching the online portal, case numbers SFL74801 or higher need a zero added before the first digit (e.g., SFL075000).
- ✓The volunteer family law settlement conference program (STBA) is suspended for the rest of 2026 as of July 1, 2026.
Processing Times
Sonoma County processes family law filings at the Hall of Justice in Santa Rosa. Allow 5–10 business days for processing. Check sonomacourt.org for current wait times.
California has a mandatory 6-month waiting period. In a traditional divorce it runs from the date your spouse is served; in a joint petition (SB 1427) it runs from the date you file, because there is no service step. Either way this is the legal minimum — no divorce can be finalized before this period passes, regardless of how quickly you complete your paperwork.

This is the legal minimum. The total timeline depends on how quickly you complete paperwork, exchange disclosures, and reach an agreement. Sonoma County processes family law filings at the Hall of Justice in Santa Rosa. Allow 5–10 business days for processing. Check sonomacourt.org for current wait times.
Do I need a lawyer to file for divorce in Sonoma County?
No. You are not required to have a lawyer for an uncontested divorce in California. Many people successfully file on their own or with the help of a document preparation service like MutualFile. If your case involves complex issues, consulting an attorney is recommended.
What forms do I need to file for divorce in Sonoma County?
The basic forms include the Petition (FL-100), Summons (FL-110), and if you have children, the Declaration Under UCCJEA (FL-105). You'll also need financial disclosure forms (FL-140, FL-142, FL-150) and a final Judgment (FL-180). MutualFile generates all required forms automatically based on your answers.
Where do I file for divorce in Sonoma County?
At the Family Law & Probate Clerk's Office in the Civil and Family Law Courthouse, 3055 Cleveland Avenue, Santa Rosa (not the Hall of Justice). Clerk hours are 8:00 a.m.–3:30 p.m. weekdays. You can also e-file, use the drop box by the entrance, or mail your papers to that address.
Do I have to e-file my Sonoma County divorce if I don't have a lawyer?
No. Sonoma's Local Rule 17.22 makes e-filing mandatory for represented parties, but self-represented parties are exempt. You may still e-file through Odyssey eFileCA if you prefer, and e-filing fees are waived if you show you cannot afford court fees.
What do I need to file divorce papers by mail or drop box in Sonoma County?
Include the original plus two copies of each form, the filing fee (or a fee waiver request), and a self-addressed stamped envelope large enough for your filed copies. Without the envelope the clerk will not return your copies, and rejected papers come back by mail, so in-person filing is safer near a deadline.
