How You Can Serve the Other Parent
Service means officially delivering legal documents to the other parent in a way the court recognizes. How you serve matters — different methods have different timelines, and using the wrong method can delay or derail your case.
The main methods
Personal Service
Someone (not you) physically hands the documents to the other parent. The most straightforward method — no extra days added to your deadlines. The server must be 18+ and not a party to the case.
Service by Mail
Documents are mailed to the other parent's last known address. Allowed and common, but adds 5 calendar days to every deadline. If your hearing requires 16 court days' notice, you must mail 16 court days + 5 calendar days in advance.
Service by Email
Only valid if the other party has agreed to electronic service in writing — through a signed agreement or court order. You cannot simply email documents and assume they're properly served.
Substituted Service
If personal service fails after reasonable attempts, a process server may leave documents with a responsible adult at the other parent's home or work, then mail a copy. Requires a declaration of diligence.
You cannot serve your own documents. The server must be 18+ and not a party to the case. After serving, they complete a Proof of Service form — FL-330 for personal service, FL-335 for mail. A professional process server will typically file this with the court directly. If a friend or family member served, they hand it back to you and you file it before your hearing. Without a filed Proof of Service, the judge has no evidence the other parent was properly notified — and your hearing may be continued even if the other parent doesn't show up.
If you genuinely don't know where the other parent lives or works, California law has a process — but you must show the court you made a real effort to find them first.
Step 1 — Due Diligence: Document every attempt to locate them. You'll submit this as a declaration: checked last known address, searched online (social media, public records), asked mutual contacts, contacted the DMV or post office for a forwarding address.
Step 2 — Service by Publication: If due diligence fails, ask the court for permission to serve via a notice published in a court-approved newspaper. This is slow (4 weeks of consecutive publications) and expensive — but it satisfies the legal requirement and your case can proceed.
Step 3 — Service by Posting (low-income option): If you have a fee waiver and can't afford publication, you may be able to request the court clerk post the notice at the courthouse. Ask your county's self-help center if this applies.
Key Deadlines in California Family Court
These are the most common deadlines pro se parents encounter. Missing them doesn't always end your case — but it can cost you your chance to be heard at a specific hearing.
| Situation | Deadline | What happens if missed |
|---|---|---|
| Responding to a Petition (FL-120) | 30 calendar days | The other parent can request a default judgment — the court may grant everything they asked for without a hearing |
| Serving an RFO (Request for Order) | 16 court days before hearing +5 if by mail |
Hearing may be continued or the judge may refuse to hear the motion |
| Filing a Responsive Declaration (FL-320) | 9 court days before hearing | Judge may not consider your response — or may allow it at their discretion |
| Filing a Reply Declaration | 5 court days before hearing | Judge may not consider it if filed late — discretion applies here too |
| Requesting a Continuance | As early as possible | Last-minute requests are often denied, especially if the other side objects |
| Submitting a Proposed Judgment or Order | Typically 10–20 days after hearing | Delays your final orders — a verbal ruling from the judge is not enforceable until a written order is signed |
Judges have discretion to accept late filings — but never count on it. A judge who allowed a late filing last time may not next time. Follow the deadlines. If you miss one, show up anyway and explain — don't assume your case is over.
Know the difference
📅 Calendar Days
Every day counts
Weekends, holidays, all of it. 30 calendar days from March 1st = March 31st — no exceptions.
🏛️ Court Days
Only courthouse-open days
Weekends, state holidays, and court holidays are skipped. 16 court days = roughly 3–4 calendar weeks.
Start counting the day after the event occurs — not the day of. When in doubt, give yourself extra days. One miscounted day is not worth the risk.
What Happens When Deadlines Are Missed
Here is where the rules and reality can look very different. Click any scenario below to see what the rule says — and what can actually happen in practice.
The rule: After 30 days, you can request a default. The court may grant everything in your petition without a hearing.
The reality: Defaults are common and courts do grant them — but a judge may still review the terms, especially anything involving children. Child custody and support defaults get more scrutiny than property issues. The other parent can also move to set aside the default if they have a legitimate reason for missing the deadline.
The rule: If the other parent was properly served and doesn't appear, the judge may proceed without them and grant what the moving party is requesting.
The reality: This happens regularly — and judges often do grant the moving party's request. However, it is not automatic. The judge will first confirm proper service was completed. If you don't have a filed Proof of Service, the hearing may be continued even if the other parent is a no-show. Come prepared with your Proof of Service in hand.
The rule: A late responsive declaration may not be considered by the judge. You may lose your opportunity to be heard at that hearing.
The reality: Show up anyway. Judges sometimes allow late filings — particularly if you're self-represented and explain the situation honestly. Come with your documents, be upfront about what happened, and ask permission to be heard. The worst the judge can say is no. Staying home guarantees you won't be heard.
The rule: A declaration served too close to the hearing — say, the night before — does not meet the required notice period. The judge can exclude it or continue the hearing.
The reality: Judges have wide discretion here and they don't always enforce it. You may walk into a hearing where the judge has already read a declaration you received the night before with no time to respond. This happens. Your best move is to say clearly, on the record: "Your Honor, I was not served with this declaration until [date], which did not give me adequate time to prepare a response. I am requesting either a continuance or an opportunity to file a written reply." Even if the judge proceeds, your objection is now part of the record.
The rule: If the other parent was not properly served, the hearing should not proceed. The court should continue it and require proper service.
The reality: This usually does result in a continuance — which is frustrating but protects everyone's due process rights. If the other party claims improper service, be ready to show your filed Proof of Service. If you're the one who wasn't properly served, raise it immediately when the hearing is called.
The rule: Court orders are enforceable the moment they are issued. Violating one — even one you disagree with — is a separate matter from contesting it.
The reality: Judges notice. If you are fighting an order in court while simultaneously not following it, it damages your credibility significantly. The proper path is to follow the order and file a motion to modify it if you believe it is wrong. Taking matters into your own hands almost always backfires.
