FL-335 - California Judicial Council
Proof of Service by Mail
Confirms that court documents were mailed to the other party — completed and signed by the person who did the mailing.
What this form does
Many documents in a family law case can be served by mail rather than in person. FL-335 is the proof that mailing happened — completed and signed under penalty of perjury by the adult who did the mailing. Required for responses, financial disclosures, and most documents after the initial service.
Who needs to file it
Completed by any adult who mailed court documents on your behalf — not you.
When to file it
File after documents have been mailed to the other party.
What happens after you file
Filed with the court to confirm service. The case can proceed.
Filing fee: No separate filing fee.
