How to Respond to Child and Spousal Support Papers in California

May 21, 2025

Being served with child support or spousal support papers can feel overwhelming. Whether you're newly navigating divorce or dealing with post-judgment support modifications, it is critical to understand your rights and legal options in California. Failing to respond appropriately could lead to default judgments, wage garnishment, or enforcement actions.

This guide explains the process, your responsibilities, and how to protect your interests under California family law.

Understanding Support Orders in California

Support orders are legally binding directives issued by a court that require one party to provide financial assistance to a former spouse or child. In California, these orders fall under two primary categories:


Child support:

Payments made to ensure a child's basic needs are met.


Spousal support (alimony):

Payments made to a former spouse to maintain a standard of living post-divorce or separation.


These orders may arise during a divorce proceeding, legal separation, or even after a judgment has been finalized. Regardless of when they’re issued, once served, it is essential to respond promptly.

Served with Support Papers: What Happens Next?

When you’re served with support orders, you typically receive a Summons and Complaint for child or spousal support. These documents notify you that the other party is requesting financial support and that you are now a part of a legal action.


Timeline to Respond

You usually have 30 calendar days from the date you were served to file a response. Ignoring these papers could result in the court granting everything the other party requested by default.



Your formal response is typically called an Answer (Form FL-320), which gives you an opportunity to agree, dispute, or provide your own proposed terms regarding the support obligations.

Filing Your Response: Step-by-Step

Step 1: Read the Papers Carefully

Understand what is being asked of you. Review all forms, including financial disclosures and any temporary support orders.


Step 2: Fill Out the Required Forms

Commonly required forms include:

FL-320 (Responsive Declaration to Request for Order)

FL-150 (Income and Expense Declaration)

FL-155 (Financial Statement Simplified, in some cases)


You must provide accurate financial information. Omitting assets or underreporting income can backfire during proceedings.


Step 3: File and Serve the Forms

File your completed forms with the family court in your county and serve a copy to the other party (or their attorney) through a third party who is over 18 and not involved in the case.

The Role of Financial Disclosures

In California, both parties are legally obligated to disclose their finances during support proceedings. This requirement ensures transparency and allows the court to calculate fair support amounts.


Documents you may need to gather include:

Pay stubs

Tax returns

Bank statements

Proof of recurring expenses



Failure to provide truthful disclosures may lead to court sanctions or an unfavorable support ruling.

How Support Is Calculated in California

Child Support Calculation

California uses a statutory formula outlined in Family Code §4050 to calculate child support. Key factors include:

  • Income of both parents
  • Time each parent spends with the child (timeshare percentage)
  • Health insurance costs
  • Tax filing status

You can estimate child support payments using the California Guideline Child Support Calculator provided by the Department of Child Support Services.

Spousal Support Considerations

For temporary spousal support (while the divorce is pending), California courts may use a formula similar to the one used for child support. Permanent or long-term spousal support, however, considers broader factors such as:

  • Length of the marriage
  • Each party's earning capacity
  • Standard of living during the marriage
  • Age and health of both spouses

Modifying Support Orders

Support obligations are not necessarily permanent. If your financial circumstances significantly change—for example, job loss, illness, or a substantial increase in income—you can request a modification of the existing order.

You must file a Request for Order (FL-300) to initiate the modification process and demonstrate why a change is warranted. Waiting too long to request a change could result in arrears (back payments) that cannot be retroactively reduced.

What Happens If You Don’t Respond?

Ignoring support papers can have serious consequences:

  • Default Judgment: The court may approve the support amount requested by the other party without your input.
  • Wage Garnishment: Your employer could be ordered to deduct payments directly from your paycheck.
  • Property Liens: Your assets could be affected by a lien to collect unpaid support.
  • Driver’s License Suspension: Delinquent child support may lead to DMV penalties.

Avoid these outcomes by responding timely and seeking legal guidance.

Enforcing Support Orders in California

Once an order is in place, the receiving party can take legal steps to enforce it. According to this California Divorce Guide article, enforcement methods may include:

  • Income withholding orders (wage garnishment)
  • Bank account levies
  • License suspension (including professional licenses)
  • Contempt of court proceedings


Support enforcement can be initiated through the Department of Child Support Services (DCSS) or privately through the court.

When to Seek Legal Support

Support proceedings can quickly become complex, especially if:

  • There are disputes about income or custody
  • One party is self-employed or hiding assets
  • You are concerned about arrears or contempt charges
  • You need to file a motion to modify existing orders

Legal representation can help ensure your rights are protected, your paperwork is accurate, and you present a strong case.

Responding to Support Orders Is Not Optional

If you’ve been served with child or spousal support papers in California, you must act fast. Time is limited, and the consequences of inaction can be long-lasting. Filing a proper response, disclosing accurate financials, and understanding your options are all essential to protecting your legal and financial future.
