If you handle child custody cases in California, you have likely come across FL-105 — the Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). While it may look like just another form, FL-105 plays a critical role in establishing the court’s authority to make custody orders.

Filing an incomplete or inaccurate FL-105 can lead to delays, requests for correction, or jurisdictional complications — and because the form is jurisdictional, even small omissions can create disproportionate problems. For attorneys and paralegals, the real objective is to prepare it accurately the first time and to make sure it aligns with the rest of the filing package.

 

Why FL-105 Matters

The UCCJEA is a uniform law adopted by every state, including California, to determine which state has jurisdiction to make child custody decisions. Its purpose is to prevent conflicting custody orders between states and help ensure that valid custody orders are respected and enforceable nationwide.

FL-105 gives the court the information it needs to determine whether California has jurisdiction over the child custody matter. Without it, the court lacks a basis to assert jurisdiction and cannot move forward on custody-related requests.

 

When Is FL-105 Required?

You must file FL-105 in family law cases involving child custody or visitation, including:

       Dissolution of marriage matters involving minor children

       Legal separation matters involving child custody or visitation

       Parentage actions

       Domestic partnership cases involving children

       Requests for custody or visitation orders

 

It is typically filed with the initial petition or with a request involving custody issues, and it remains important whenever the court needs to confirm jurisdiction.

 

How to Complete FL-105: Section-by-Section Guide

1. Child Information

List each child’s full name and date of birth. If there are more children than the form allows, attach an additional page using MC-020 or another approved continuation page.

2. Home State Information

Identify where each child has lived during the previous five years and with whom. If the child has lived in California for the last six months, list California as the home state for that time period.

3. Previous Custody Cases

Disclose whether there are any other custody cases concerning the child in California or another state. Include available information such as the case number, court name, and current status.

4. Other People Claiming Custody

List all persons not already named in the case who may claim a right to custody or visitation. Include names, addresses when required, and the relationship to the child.

5. Domestic Violence Orders & Special Circumstances

Answer the questions about domestic violence restraining orders, emergency protection orders, abandoned children, and whether the child is the subject of another custody proceeding. Do not skip any question even if the answer seems unimportant — blank fields signal an incomplete declaration.

 

Mistakes and Best Practices

Because FL-105 is jurisdictional, errors here have outsized consequences compared to other forms. The most common problems to avoid:

       Failing to list every child involved in the case

       Leaving out prior custody matters in other states

       Using incomplete residence history

       Skipping a question because the answer seems unimportant

       Submitting an unsigned or inconsistent declaration

 

And the workflow habits that prevent them:

       Gather the child’s five-year residence history during intake rather than reconstructing it at filing time

       Confirm whether any other state has issued custody or protection orders before filing

       Use the same party names, child names, and matter details across all related forms

       Recheck the declaration whenever new facts emerge that might affect jurisdiction

       Review FL-105 alongside the petition and any custody-related requests before submitting
