Child support basics
By law, both parents must support their children
Sometimes parents can agree on how to share this responsibility without going to court. But, if you and the other parent can’t agree, you can ask the court for a child support order.
Child support is the amount of money that a court tells a parent to pay every month. This money is to help pay for the children’s living expenses. Usually, child support is paid to the person primarily caring for the children. But, there may be exceptions based on how much each parent earns.
A child support order will say how the parents share the financial responsibility. It can also require an employer to deduct the support directly from a paycheck.
The duty to pay support typically ends when a child turns 18 and graduates high school
Child support ends when the child:
- turns 18 and graduates from high school (if still in high school full time) or turns 19, whichever happens first
- gets married or enters a domestic partnership
- joins the military
- is emancipated
- dies
The duty to pay child support can continue after a child turns 18 (or 19) if the child is disabled and can’t support themselves, or if the parents agree for support to continue.
How the court calculates child support
Courts use the California “guideline”
The guideline looks at:
- How much money each parent makes
-
How they file taxes
-
How much time they spend with the children
-
Other factors
There is a free online child support calculator that figures out how much support a parent needs to pay (link opens in a new tab).
How to get or change a child support order
If you need an order and don't already have one
You can ask for a court order:
- by filing papers in an existing family law case in California (like a divorce or parentage case) involving the child
- by starting a new case if you don't have one already
The steps you take and the forms you need will be different depending on your situation. And, you can also ask the Local Child Support Agency (LCSA) to help you ask for a child support order in a new case or as part of an existing case.
If you have an order and need to change it
You can ask the judge to change support if things changed since the last order, like:
-
You are now making less money
-
The other parent is now making more money
-
You are now spending more time with your children
To ask for a change in a child support order:
- If you and the other parent don't agree about the change, file a Request for Order (form FL-300 to ask to change the order.
- If you and the other parent agree on the change, turn in a written agreement for the judge to sign.
- If you have an LCSA child support case (a government child support case), follow different instructions to ask to change the order. The LCSA will also need to approve any agreement to change support.
How you get help or change your child support order is different if the local child support agency (LCSA) is involved in your case.
The LCSA will be part of your case if one of the parents:
- Is getting money from the government for your children, or
- Asks for their help
One way to tell if the LCSA is involved in your case is if the County is listed as one of the parties. For example County of San Diego v. John Doe
If you aren’t sure if the LCSA is involved, call the Child Support Customer Connect line to find out: 866-901-3212.
If your duty to pay support ended (for example, your child turned 18 and graduated high school), you can stop support payments from being taken from your paycheck.
If you need to change the order, don't wait
A judge can only change the support amount as far back as the day you filed papers asking for a change. The judge can’t make any changes to the amount before that day.
-
EXAMPLE: What happens if you waiT
- You lost your job on March 1
- You file a request with the court on July 1
By law, the judge can only change how much you owe starting July 1. The judge can’t change what you owed in March – June, even though you lost your job in March.
How to respond if you got papers asking for a child support order
Your options to respond, the forms you use to respond, and any deadlines you need to meet depend on which forms you were given. The forms should have a form number in the upper right or left-hand corner.
Get step-by-step instructions to respond to:
- Form FL-300, FL-680 or 683, or DV-100. These forms mean you have a court date. A judge may make a decision about child support at that court date.
- Form FL-100, Form FL-200, Form FL-260, or Form FL-600. These are forms that start a family law case, like a divorce. You generally have 30 days to file a response to these.
If you do not respond, a judge may make a child support order without your input.
Where to get free help
The Local Child Support Agency
The Local Child Support Agency (LCSA) makes sure the children get enough support. In some counties, their name is the Department of Child Support Services.
They may become involved in your case if either:
-
You or your child’s other parent receives cash aid for the children
-
One of you asked for their help
A lawyer from their agency will go to court for any hearings you have about child support. The LCSA is not the attorney for either parent.
If they are part of your case, they:
-
Can help you and the other parent reach an agreement
-
Must approve any agreement you make with your child’s other parent
-
Can also help either parent change the child support order in court if there has been a change
-
Will be in charge of collecting child support
