The costs that are not the filing fee
Filing is the first charge, not the only one. Sonoma County also charges:
- Clerk mail service of claim per defendant: $15
- Frequent filer more than 12 claims per year: $100
- Notice of appeal: $75
- Motion to vacate judgment: $20
- Request to postpone hearing after service: $10
None of these are optional once the case is moving, and all of them are recoverable in the judgment if you win. They are simply not quoted at the counter when you ask what it costs to file.

What it costs to serve the defendant
Sonoma County charges $15 per defendant for service. That is on top of the filing fee, and you pay it for each person or business you are suing.
- Personal service - an adult 18 or older who is not a party hands the forms to the defendant
- Substituted service - leave the forms with an adult at the defendant's home or usual mailing address (not a P.O. box) or workplace, then mail a copy
- Certified mail sent by the court clerk (offered only in some courts; a $15 clerk fee, and it often fails because the defendant can refuse to sign)
- Service by the county sheriff or marshal for a fee
- Service by a registered process server for a fee
Clerk certified mail is complete only if the defendant actually signs for it; a refused or unsigned certified-mail service does not count and will delay the case, so most filers use personal service by a sheriff or process server.
How this clerk takes payment
Superior Court of California, County of Sonoma — Small Claims accepts:
- Check or money order payable to the court
- Cash and card acceptance varies by filing location — confirm accepted payment methods with the court before filing
