California Form FL-105/GC-120: Declaration Under UCCJEA
Complete your child custody jurisdiction declaration online in 10 minutes
What is FL-105 used for?
California Form FL-105/GC-120 is a mandatory declaration used in family and probate court cases to disclose the children's five-year residence history and any other custody cases or non-party claimants, establishing California's jurisdiction under the UCCJEA.
Successfully establish California's child custody jurisdiction by providing a complete, error-free 5-year residence history for all minor children.
Omissions or gaps in the children's 5-year address history can delay your case or lead to the court staying the custody proceedings. If children have lived at different addresses, you must attach Form FL-105(A).
