Sep 18, 2025
If you're starting the divorce process in California, you've probably heard about the infamous FL-100 form. This seemingly innocent document is actually your formal petition for dissolution of marriage—and your first major step toward legally ending your marriage.
But what exactly is this form, why is it so important, and how do you fill it out without making costly mistakes? Let's break it down in plain English.
What is the FL-100 Form?
The FL-100 (Petition for Dissolution of Marriage) is the primary document you file to start a divorce in California. It tells the court your basic information, what you're asking for, and establishes the legal grounds for ending your marriage. Think of it as your formal request to the court system to dissolve your marriage.

Common Mistakes to Avoid
Incorrect jurisdiction: Filing in the wrong county can cause delays and complications
Wrong date of separation: This can significantly impact property division
Incomplete children's information: The court takes child-related matters very seriously
Failing to address spousal support: If you don't address it now, it could come back later
Vague property descriptions: Be as specific as possible about assets and debts
Missing attachments: If you need more space, use the proper attachment forms
What Happens After You File?
Once you file the FL-100 form (along with other required documents like the FL-110 Summons), you'll need to:
Have the papers legally served on your spouse
Wait for your spouse's response (they have 30 days to respond)
Complete preliminary financial disclosures
Proceed with either a settlement or court hearings
The entire process from filing to final judgment typically takes at least six months in California due to the mandatory waiting period, but can take much longer depending on the complexity of your case and how well you and your spouse cooperate.
