Official FL-100 from Judicial Council of California
Form FL-100 is the Petition—Marriage/Domestic Partnership adopted for mandatory use by the Judicial Council of California. It is the document that starts a divorce, legal separation or annulment for married couples and registered domestic partners, and it identifies every issue you want included in the judgment: custody and parenting time, child support, spousal support, separate property, community property and other requests such as restoring a former name. With JustFill you upload the blank FL-100 PDF, the AI auto-detects every field and checkbox, and you download the completed petition free.
Starting a California divorce? FL-100 is the first paper you file, and JustFill turns the official three-page Judicial Council PDF into a fillable form in your browser. It rests on Family Code sections 297, 299, 2320, 2330 and 3409. Item 1 states your legal relationship. Item 2 covers the residence requirement — six months in California and three months in the county. Item 3 records the statistical facts: date of marriage or registration, date of separation, and the time between them in years and months. Item 4 lists minor children. Item 5 states the legal grounds. Items 6 to 11 are your actual requests: custody, child support, spousal support, separate property, community property, attorney fees and a former name. Item 12 confirms you have read the restraining orders printed on the back of the summons.
What each section of FL-100 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.
Whether you are married, domestic partners registered in California, or domestic partners registered elsewhere. Check all that apply — the answer changes which residence rule applies to you.
That the petitioner or respondent has lived in California at least six months and in the county at least three months immediately before filing. If your domestic partnership was registered in California, neither of you has to be a California resident to dissolve it here.
Date of marriage or of registering the partnership, date of separation, and the elapsed time stated in years and months. Two separate blocks, one for marriage and one for registration.
Each child’s name, birthdate and age, or a statement that there are none. A child not yet born is checked separately. If there are minor children, a completed UCCJEA declaration (form FL-105) must be attached.
Divorce or legal separation on irreconcilable differences or permanent legal incapacity to make decisions; or nullity of a void marriage (incest, bigamy) or a voidable one (age at registration, prior existing marriage, unsound mind, fraud, force, physical incapacity).
Legal custody, physical custody and parenting time, each assigned to petitioner, respondent, joint or other, with the detail set out in FL-311, FL-312, FL-341(C), FL-341(D), FL-341(E) or an attachment. Then child support, and spousal or partner support: payable to, terminated, or reserved for later determination.
Separate property to be confirmed and community and quasi-community property to be divided, either listed on the form or on a Property Declaration (form FL-160); then attorney fees, restoration of a former name, and anything else.
