When you need form FL-110
The FL-110 Summons is required at the start of a divorce, legal separation or nullity case in California, and it is served together with the Petition (FL-100). It is the document that gives the court power over the respondent: it tells the other party that a case has been filed, that they have 30 calendar days after service to file a Response (FL-120) and serve it on the petitioner, and that if they do not, the court may make orders about the marriage or domestic partnership, property, custody, support and attorney's fees without them. The current form is revised January 1, 2015. Parentage cases use the FL-210 Summons instead.
- Filing a Petition for Dissolution (FL-100): the petitioner completes the Petition and the Summons at the same time and files them together; the clerk issues the Summons by stamping it with the court seal and case number.
- Notice and Acknowledgment of Receipt (FL-117): the Summons and Petition must be personally served unless the respondent agrees to accept service by mail by signing and returning this form.
- Trigger event: the petitioner's decision to start the case. The Summons cannot be served until the Petition has been filed and the clerk has issued it.
The Summons also contains the standard family law restraining orders under Family Code section 2040, which take effect against the petitioner on filing and against the respondent on service. Until the case is dismissed, judgment is entered or the court orders otherwise, neither party may remove the minor children from California or apply for new passports for them, cash, borrow against, cancel or change the beneficiary of any insurance, transfer or dispose of property outside the usual course of business or for the necessities of life, or create or change a nonprobate transfer, without the other party's written consent or a court order. Under Family Code section 233 these orders are enforceable anywhere in California by any law enforcement officer who has received or seen a copy of them. Once the Summons and Petition are served, the respondent's 30 days begin, and the six-month waiting period under Family Code section 2339 starts running toward the earliest date a dissolution can become final.
1. Obtain the form. Download the FL-110 Summons from the California Courts website or get a copy from your local family law clerk.
2. Complete the form. Fill in the names of the petitioner and respondent exactly as they appear on the Petition, the court's name and address, and your name, address and phone number as the person filing. Do not fill in the case number or the clerk's section; the clerk does that.
3. File it with the Petition. File the Summons together with the Petition (FL-100) and, if there are children, the FL-105, with the clerk of the Superior Court in the county where you or your spouse have lived for the last three months. The clerk stamps the Summons with the seal, dates it and assigns the case number.
4. Pay the filing fee or request a waiver. The 2026 Statewide Civil Fee Schedule lists $435 for a petition for dissolution, legal separation or nullity, with a total of $450 in Riverside and San Francisco counties. If you cannot pay, file a Request to Waive Court Fees (FW-001) with the Petition; the court may later order repayment of waived fees.
5. Serve the forms. Someone who is at least 18 and not a party must personally hand the issued Summons, the Petition, any attachments and a blank Response (FL-120) to the respondent, unless the respondent signs a Notice and Acknowledgment of Receipt (FL-117) to accept mail service. The server completes the Proof of Service of Summons (FL-115), which you file with the court. The respondent's 30 days to respond and the six-month waiting period both run from the date of service.
