The local child support agency has filed this lawsuit against you. This lawsuit says you and the other parent are the parents of each child named in this Complaint and that the obligor may be required to pay child support. The attached proposed Judgment Regarding Parental Obligations names you and the other parent as parents of each child listed below and, if there is an amount stated in item 6 of the proposed Judgment, orders the obligor to pay support for these children. If you disagree with the proposed Judgment, you must file the attached Answer with the court clerk within 30 days of the date that you were served with this Complaint. If the amount of child support in the proposed Judgment is based on actual income and you do not file the Answer, the proposed Judgment will become a final determination that you are the parent and responsible for support. If the amount of child support in the proposed Judgment is based on earning capacity, the court will hold a hearing before entering a judgment. If you do not file the Answer or appear at the hearing, the court will enter a judgment without your input. If you are required to pay child support, the payments may be taken from your pay or other property without further notice.

Form FL-600 example filled out, example: a child support agency lists one child
A local child support agency lists one child on FL-600. It asks the court to establish parentage and support, so item 3 stays empty. Lee Example and Pat Example are the parents, and no declaration of parentage is on file with the local child support agency or the county welfare department, so item 2b stays empty. Nothing goes in Modify Order or Beginning Date because no order is being modified. The picture shows page 2 only, and all its values are invented.

California Form Fl 600 PDF Details

The California Fl 600 form, officially titled "Summons and Complaint or Supplemental Complaint Regarding Parental Obligations," is a key document in California family law. The local child support agency uses this form to initiate legal proceedings under California Family Code 17400 and 17406. The agency typically uses it when establishing parentage, setting a support order, or modifying an existing one.

When a judge reviews this document regarding parental obligations, they examine the allegations and determine what each person must pay monthly. Anyone who receives this notice should respond within the required timeframe to protect their rights.

What Does Form Fl 600 Cover?

This legal action regarding parental obligations addresses several key areas. It identifies both parents of the children involved in the case. It sets forth specific allegations about the parental relationship and the obligation to pay monthly amounts. It also outlines what the agency is asking to be ordered, which may include a judgment establishing the parental relationship, a support order, and reimbursement for past payments made.

The form is typically presented alongside the proposed Judgment Regarding Parental Obligations (Form FL-630). Together, these documents give a thorough view of the agency's position and what the obligor is expected to pay monthly.

What to Expect After Being Served

A person who receives this notice must submit a written response within 30 days of being served. Failing to respond can result in a default judgment. That means a judge may issue an order without hearing the person's side of the case. A legal aid organization or family law attorney can help prepare a proper response and protect each parent's rights throughout the process.

After a response is submitted, a hearing is typically scheduled. At the hearing, both parties can present their positions on parentage and the appropriate monthly amount to pay. The judge then issues a final order that both parties must follow.
