California Child Support Modification – Required Forms
Need to lower or raise your child support in California? You must file specific court forms to modify the order. This article lists the exact required forms and explains the filing steps. You will learn how to complete the request and avoid common delays. Get the clear path to adjust your payment legally.
When to Modify California Support
If you pay or receive child support in California, you might wonder when the amount can change. The law says you can ask for a modification when something big in your life changes. This is called a change in circumstances.
For example, if you lose your job or get a new one with much higher pay, the court may change the order. Also, if your child starts living with the other parent more often, the support amount should be looked at again.
| Common Reason | What You Need |
|---|---|
| Loss of job | Proof of lower income |
| Child medical need | Doctor bills |
| New custody plan | Schedule with child |
Signs It Is Time to Act
Some parents wait too long to ask for help. California lets you request a review every three years even without a big change. If your money situation is different for at least 30 days, you should file the forms soon.
California law lets a parent ask for child support change when income drops by 20% or more.
You can use forms like FL-300 and FL-150 to start. Keep copies of pay stubs and tax returns to show the court your new numbers. Acting early helps you avoid owed back payments.
Mandatory Forms for Modification of Child Support in California
If you want to change child support in California, you must give the court the right forms. The most important paper is form FL-300, which is called a Request for Order. This form tells the judge that you want to modify the existing child support amount.
You also need to show your current money situation. Most parents use form FL-150, the Income and Expense Declaration, or the shorter FL-155 Financial Statement. For example, if you lost your job, you write your new income on these forms. Court data shows that about 4 out of 10 filings get sent back because the money form is missing or incomplete. Filling every box helps you avoid delay.
The court will not change your child support without a finished FL-300 form.
List of Required Forms
Here is a simple table that shows the mandatory forms and what they do. Keep this list near your desk when you prepare your papers.
| Form Number | Name | Why You Need It |
|---|---|---|
| FL-300 | Request for Order | Asks the court to change support |
| FL-150 | Income and Expense Declaration | Shows your earnings and bills |
| FL-155 | Financial Statement (Simplified) | Short version if your case is simple |
| FL-191 | Child Support Case Registry Form | Gives case details to state registry |
Steps to Complete Your Filing
Follow these easy steps so your modification request goes smoothly:
- Fill out FL-300 with the old order details and what you want changed.
- Attach FL-150 or FL-155 with pay stubs from the last two months.
- Make two copies of every page before going to the court clerk.
- File the forms and pay the fee, or ask for a fee waiver using form FW-001.
After you file, the other parent gets a copy and a hearing date is set. Bring your forms to the hearing and explain your change in life, like less work or higher child costs. Good preparation makes the judge’s job easier and helps you get a fair result.
Completing FL-300 Request to Modify Child Support in California
The FL-300 form is called Request for Order. You use it when you want a judge to change your child support amount. This form tells the court what you want and why.
Before you start, gather your pay stubs, tax returns, and the current order. You need these to fill out the money parts correctly. A clear form helps the judge make a fair choice.
Step-by-Step Guide for Filling Out FL-300
First, write your name and case number at the top. Then check the box that says “child support” in item 1. If you need to change the amount, explain your reason in item 4 with short facts.
Here is a simple list of the main items you must complete:
- Item 1: Choose the orders you ask for, like child support change.
- Item 2: Write if you have a prior order and its date.
- Item 4: Explain why the change is needed, such as job loss or higher bills.
- Item 5: List the forms you attach, like FL-150 (income declaration).
The court looks at your income and the other parent’s income. Use the table below to see common papers you need with FL-300:
| Form Name | What It Does |
|---|---|
| FL-150 | Shows your income and expenses |
| FL-155 | Simple child support worksheet |
| FL-320 | Optional form for scheduled orders |
Fill out the FL-300 with honest numbers because mistakes can slow down your hearing.
After you finish, make two copies. Take them to the court clerk and file. You must also send a copy to the other parent. This step is called service.
Preparing FL-150 Declaration for Child Support Change
When you want to change child support in California, you must fill out form FL-150. This form is called the Declaration of Disclosure, and it shows your money situation to the court. The judge uses it to decide if your support amount should go up or down.
To start, get the latest FL-150 from the California courts website. Write your name, case number, and date at the top. Then list your job income, any other money you get, and your monthly bills. Be honest because the court checks these numbers.
Key Parts of the FL-150 Form
The FL-150 has boxes where you write your money details. You need to fill out part 1 about your job and part 2 about other income like rent or gifts. Then you list what you pay for housing, food, and child care.
Here is a quick look at the main sections:
| Form Section | What to Write |
|---|---|
| 1. Employment | Your boss name, pay, and hours |
| 2. Other Income | Money from jobs, help, or benefits |
| 3. Monthly Expenses | Rent, bills, and kids costs |
Make sure you sign the form. If you skip a part, the court may send it back.
Easy Tips to Fill FL-150
Filling this form can feel hard, but small steps help. Use your last tax return to check numbers. Ask your employer for a pay letter if you lost stubs.
File the FL-150 with the court before your hearing date to avoid delays.
Keep a copy for yourself and mail one to the other parent. This way everyone sees the same facts.
Submitting to California Court
When you need to change child support in California, you must send your finished forms to the court. The main form is the Request for Order (FL-300) and the Income and Expense Declaration (FL-150). You file these at the county court where your case lives.
After you file, the court sets a date for a hearing. You must serve the papers to the other parent at least 16 days before the hearing if they live in California. If they live far away, you get more time. This step is required so the judge can look at your request.
The court will not change support unless you serve the other parent first.
Many parents worry about the cost. The filing fee is about $60 for a Request for Order, but you can ask for a fee waiver using form FW-001 if you have low income.
Steps to File Your Forms
Follow these easy steps to submit your packet. Keep a copy of everything for yourself.
- Fill out FL-300 and FL-150 with your new income info.
- Make two copies of each form.
- Take the forms to the clerk’s window at the court.
- Pay the fee or submit a fee waiver.
- Ask the clerk for a hearing date stamped on your papers.
The table below shows key timelines for serving papers based on where the other parent lives.
| Location of Other Parent | Days to Serve Before Hearing |
| California | 16 days |
| Another U.S. state | 20 days |
| Outside the U.S. | 28 days |
Once served, fill out the Proof of Service (FL-330) and file it with the court. This shows the judge that the other parent got the papers. Then you just wait for your court day and bring your evidence.
After Court Approval Steps
Once the court approves the modification, the new child support order takes effect as specified in the judgment. Obtain a certified copy from the clerk and verify that all payment amounts and dates reflect the changes requested in your forms.
Notify the employer or state disbursement unit if automatic wage deductions must be adjusted under the revised order. Retain copies of the signed order and any proof of service to protect your rights if future disputes arise.
