How to File for Child Custody in California

In California, child custody is divided into two types, physical and legal custody. Physical custody is with whom the child lives on a daily basis. Legal custody, on the other hand, applies to who makes decisions about their welfare, like where to attend school and what type of medical treatment they need.

Around half of custodial parents have legal child custody orders. These orders can help protect the interests of the child and the custodial parent. To file for child custody in California, you need to:

  • Determine the correct place to file, which, in California, must be with the Superior Court in the county where you reside, like the Civil and Family Law Courthouse on Cleveland Avenue in Santa Rosa.
  • Prepare the appropriate forms for filing for child custody, which can be found online at the California Court website or at your local county courthouse
  • Submit the forms to the appropriate place, which is the Superior Court for your county in California, and pay the necessary court filing fees
  • Serve the other parent
  • Begin the child custody process, which can involve attending hearings, mediation, and more to develop an appropriate child custody plan

Because child custody laws in California can be complex and ever-changing, having a child custody attorney on your side can make a big difference.

Types of Child Custody in California

While child custody is divided into two types, it can be further divided by the types of custody arrangements. The types are:

  • Sole legal custody, in which all of the decisions are made by only one parent
  • Joint legal custody, where both parents work together to make decisions for their child
  • Sole physical custody, meaning the child lives with only one parent, but the other parent might be granted visitation
  • Joint physical custody, which means the children live at both households

The court usually prefers to grant joint custody so that the child can have a relationship with both of their parents, but this decision is made on a case-by-case basis depending on the best interest of the child.

FAQs

How Much Does It Cost to File for Custody in CA?

The cost to file for child custody in California varies depending on the circumstances. Complex cases usually cost more since the attorney needs more time to work on the case, and there may be more court filing fees.

Custody disputes, disagreements about the parenting plan, filing multiple motions in court, and more high-conflict communication between parents can significantly add to the cost. Working with a child custody lawyer can help you get an idea of what your costs might be.

What Forms Do I Need to File for Child Custody in California?

California requires a variety of forms in order to file for child custody. Three of them are necessary, including Form FL-260, which is the original petition used for filing for child custody; FL-210, which is a summons; and FL-105, which is a declaration under the Uniform Child Custody Jurisdiction and Enforcement Act. Other forms are optional and depend on your specific child custody case. A child custody attorney can help you determine which are appropriate for you.

How Do I Start the Process of Child Custody in California?

To start the process of child custody in California, contact a child custody lawyer who can help you through each step and help protect your rights and interests. You might want to locate your courthouse, like the Historic Courthouse on Brown Street in Napa, or elsewhere, depending on what is closest to you. Filling out the necessary forms can be among the first steps, and having your lawyer guide you through that can help make certain it is done correctly.

What Is the Biggest Mistake in a Custody Battle?

One of the biggest mistakes a parent can make during a custody battle is to prioritize their own needs over the needs of their child. There are many emotions involved in such a sensitive matter, but it is still important to maintain a level of focus that helps to put the child’s needs first. The court’s first priority is the best interest of the child, so having that same goal can help the process move more smoothly.
