How to Serve Court Papers in California Family Court

Why service matters

The other party has a constitutional right to know about the case and have time to respond. If you do not serve them properly, the judge cannot hear your case. Improper service means your hearing gets continued (delayed) or your case gets dismissed entirely.

Service is not optional. It is a legal requirement for every filing in family court. Even if the other parent already knows about the case, formal service must be completed and documented.

Types of service

California family court recognizes three methods of service. Which one you can use depends on the type of filing and whether the other party has already been served in the case.

Personal service

Someone physically hands the papers to the other party. This is required for the first filing in a case (such as an FL-300 when no case exists yet) and for emergency filings that need shortened time. Personal service is the most reliable method because there is no question the other party received the documents.

Mail service

Copies are sent by first-class mail to the other party's last known address. Mail service adds 5 calendar days to the deadline. It is only allowed after the initial personal service has been completed in the case.

Electronic service

Both parties must consent to electronic service in writing. E-service is becoming more common and does not add extra days to the deadline. If the other party has an attorney, the attorney can often accept e-service on their behalf.

Service deadlines

Missing a service deadline is one of the most common reasons hearings get continued. Count carefully.

• Personal service: At least 16 court days before the hearing.
• Mail service: At least 16 court days + 5 calendar days before the hearing (the “mail add-on”).
• Electronic service: At least 16 court days before the hearing (no extra days added).
• Shortened time: You can ask the judge for a shorter deadline through an ex parte application — usually 4–5 court days.

Who can serve papers

Anyone who is at least 18 years old and not a party to the case can serve papers. Common options include:

• A friend or family member who is not involved in the case and is willing to fill out the proof of service form.
• A professional process server ($50–$150 in most areas). They are experienced, reliable, and their declarations carry weight with the court.
• The county sheriff ($40–$60 in most counties). The sheriff's office will attempt personal service at a specified address.

Proof of service

After service is complete, the person who served the papers must fill out a Proof of Service form. This form tells the court that the other party was properly notified. File it with the court before your hearing.

• FL-330: Proof of Personal Service — used when papers were physically handed to the other party.
• FL-335: Proof of Service by Mail — used when papers were mailed.

What to serve

Serve copies of everything you filed with the court. Keep your originals — only serve copies. A typical service packet for a Request for Order includes:

• FL-300 (Request for Order)
• MC-030 (your declaration)
• FL-150 (Income and Expense Declaration, if applicable)
• All attachments and exhibits
• Any proposed orders
• A blank FL-320 (Responsive Declaration) for the other party

Missing even one document from the service packet can give the other party grounds to request a continuance. Double-check your packet against the court's filing receipt before handing it to the person serving.
