What forms do I need to file with an FL-300 for custody in California?
Quick answer
The FL-300 Request for Order is the main form. For custody or visitation, the Judicial Council checklist says you may also need FL-105, FL-311, FL-312, and the FL-341(C), (D), and (E) attachments, and if you also ask for child support you need a current FL-150 Income and Expense Declaration.

What the law says
The FL-300 information sheet, item 3, is the forms checklist. For child custody or visitation (parenting time) it lists FL-105 (Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act), FL-311 (Child Custody and Visitation (Parenting Time) Application Attachment), FL-312 (Request for Child Abduction Prevention Orders), FL-341(C) (Children’s Holiday Schedule Attachment), FL-341(D) (Additional Provisions, Physical Custody Attachment), and FL-341(E) (Joint Legal Custody Attachment). For child support it calls for a current FL-150, or FL-155 if you qualify. Emergency orders add FL-305 and a declaration about notice, such as FL-303. If you plan to have witnesses testify, you may want to use FL-321 (Witness List).
California Rules of Court, rule 5.111 requires a supporting declaration with the FL-300 and limits it to 10 pages unless the court gives permission; item 9 of the FL-300 states the same limit. Rule 5.92(b)(3) requires the FL-150 with any child support request.
What to do next
Make at least two copies of the full packet (FL-300-INFO item 6) and file it to get a hearing date. Then have it served with a blank FL-320, as rule 5.92(f)(4) requires. If you cannot afford the filing fee, FL-300-INFO item 8 points to FW-001 and FW-003.
