What is FL-100?

Starts a California family-law case to dissolve (divorce), legally separate, or annul (nullity) a marriage or domestic partnership. The petitioner files this with FL-110 (Summons) and pays the filing fee (or applies for a fee waiver on FW-001).

What happens if you miss the deadline: If residency requirement is not met, the court can convert the petition to a legal separation; the petitioner can amend to a dissolution once residency ripens.

How to file

Filing fee
First-appearance fee for a family-law petition is set by Cal. Gov. Code section 70670 and the Judicial Council uniform fee schedule. As of 2026 the fee is approximately $435-$450; check selfhelp.courts.ca.gov for the current amount. Pro se petitioners who cannot afford the fee file FW-001 (fee waiver) at the same time. The fee waiver covers the petition AND the response from the other side.
Filing method
in-person, mail, efile (county-specific; most California family-law courts accept e-filing)
Filing deadline
There is no deadline to file a divorce. Residency must be met at the time of filing for a divorce: at least one spouse has lived in California for 6 months and the filing county for 3 months (Family Code section 2320). After filing, the petitioner has 60 days to serve the respondent (a soft local-rule deadline; many counties enforce strictly via case-management orders).
How to serve
After filing, the petitioner must serve the respondent with FL-100 + FL-110 (Summons) + FL-105 (if minor children) by personal service or another statutory method (Code Civ. Proc. sections 415.10-415.50). The petitioner cannot serve themselves; a non-party adult or process server must serve. Service is documented on FL-115 (Proof of Service of Summons - Family Law).
Wet signature
Yes, sign in pen after printing.
Notarization
No
Original and copies
One original to the clerk plus 2 copies (one for the petitioner's records, one to be conformed and served on the respondent). Some counties require additional copies; check local rules.

Common pitfalls

Three highest-leverage checks for the AI review on FL-100. (1) Residency (item 2) MUST be checked for a divorce of marriage; the only exception is item 1b (CA-established domestic partnership). (2) UCCJEA: if item 4b indicates minor children, the petitioner MUST attach FL-105 (UCCJEA Declaration) per Family Code section 3409. (3) Date of separation (item 3) directly affects community property division because earnings and acquisitions after separation are separate property. Choose this date carefully and consistently with FL-150 income disclosures.
