FL 430 – Ex Parte Application to Issue, Modify, or Terminate an Earnings Assignment Order
If you’re going through a divorce or custody case in California, understanding how support enforcement works is essential. FL-430 is the Judicial Council form used to direct an employer to withhold support payments directly from a paycheck.
This form has been in effect since January 1, 2014, and applies in every California county, including Orange County. At Pinkham & Associates, APLC, we regularly prepare and file FL-430 in divorce and custody matters.
- FL-430 covers child support, spousal support, and family support
- It functions as a wage garnishment mechanism under california family law
- The court uses this form to issue, modify, or terminate an earnings assignment order
- Once signed by a judge, the order binds current and future employers
When You Need an Earnings Assignment Order (FL-430)
Several situations require an FL-430 filing:
- A new support order is issued after divorce or paternity establishment
- The paying party falls behind on support (typically 30+ days late)
- You need to modify amounts due to income change or child emancipation
- The support obligation has ended and the order must terminate
Example: In a 2025 Orange County case, a supported parent filed an ex parte application after three months of missed payments totaling $5,000 in arrears. The court issued the earnings assignment, and payments resumed within weeks.
Who Can Request FL-430 in a California Family Law Case
- Either party to a support order can file—most often the person owed support initiates
- The Department of Child Support Services (DCSS) may request FL-430 in Title IV-D cases
- Attorneys at firms like Pinkham & Associates, APLC, a divorce and family law firm in Orange County typically prepare and file for clients
- Self-represented parties can also file independently
- In Orange County Superior Court, FL-430 is commonly paired with FL-300 (Request for Order)
How FL-430 Works: Issue, Modify, or Terminate an Earnings Assignment
The form instructs an employer to withhold a specific dollar amount from each paycheck and send it to the State Disbursement Unit or directly to the payee as part of a broader family support order.
Three main uses:
- Issue: Create a new earnings assignment where none existed
- Modify: Change amounts, duration, or type of support being withheld
- Terminate: End the assignment when obligations are fulfilled
The parte application to issue, modify, or terminate requests can proceed on shortened notice when urgency exists. Once signed, employers must comply within 10 days or face penalties under Family Code §5250, including fines up to $1,000.

Common Problems and Legal Pitfalls With FL-430 (And How We Help)
Frequent mistakes can derail your case:
- Miscalculating support using outdated figures from an old order
- Listing the wrong employer—40% of obligors change jobs, according to DCSS data
- Failing to properly serve required documents, which can be an issue from the initial family law summons (FL-110) onward and may void the order
- Omitting arrears interest (10% annually) or failing to use an Application to Determine Arrearages (FL-490), causing unexpected obligation increases
- Using standard language for self-employed obligors, where wage assignments don’t apply
Pinkham & Associates reviews calculations against updated support guidelines, coordinates with employers to verify compliance, and develops alternative enforcement strategies for high-asset or business-owner cases, often as part of broader divorce representation in Orange County.
