In California, wage garnishment for support payments operates through an Income Withholding Order (IWO) that takes 50% to 65% of a payor's disposable earnings directly from their paycheck. Under Cal. Fam. Code § 5230, every child or spousal support order must include an automatic earnings assignment, and employers must begin withholding within 10 days of service.
Wage garnishment for divorce in California is not optional or discretionary in most cases. The state mandates an earnings assignment for nearly every support order, making payroll deduction the default collection method rather than a penalty reserved for parents who fall behind. This guide explains the statutes, dollar limits, employer duties, and enforcement tools that govern how garnished wages flow from a paycheck to a former spouse or child.

How Wage Garnishment for Support Works in California
Wage garnishment for support payments in California begins with an Income Withholding Order that a court issues automatically alongside every support order. Under Cal. Fam. Code § 5230, the court must include an earnings assignment covering both current support and any arrears whenever it orders or modifies support. Employers must start deducting within 10 days of service.
The income withholding order is the legal engine behind automatic wage deduction for child support in California. When a judge sets a support amount, Cal. Fam. Code § 5208 defines the earnings assignment as an order assigning a portion of the paying parent's earnings to the person owed support. The local child support agency or recipient serves the standardized federal IWO form on the employer. That employer then deducts the specified amount each pay period and forwards it to the California State Disbursement Unit (SDU) within seven working days of the pay date. The system is designed so the payor never personally handles the money, reducing missed payments. Because the assignment is mandatory under Cal. Fam. Code § 5230, garnishment is the rule rather than the exception, and it applies even to parents who have never missed a payment.
How Much of Your Paycheck Can Be Garnished
California garnishes between 50% and 65% of disposable earnings for support, following the federal Consumer Credit Protection Act (15 U.S.C. § 1673). The exact cap depends on whether the payor supports a second family and whether arrears exceed 12 weeks. The general limit is 50% when supporting another dependent, rising to 65% when not.
Disposable earnings means income remaining after legally required deductions — federal and state income taxes, Social Security, and State Disability Insurance. The garnishment ceiling is not a flat number; it scales with the payor's circumstances. A payor who supports a second spouse or child not covered by the order faces a 50% cap, which rises to 55% once arrears exceed 12 weeks. A payor supporting no other dependents faces a 60% cap, rising to 65% with arrears beyond 12 weeks. This escalating structure rewards staying current. The following table summarizes the four tiers that determine how much of a paycheck the income withholding order can claim.
| Payor Situation | Current Support Only | Arrears Exceeding 12 Weeks |
|---|---|---|
| Supporting another spouse/child | 50% | 55% |
| Not supporting another spouse/child | 60% | 65% |
What Income Counts as Garnishable Earnings
California defines garnishable earnings far more broadly than a regular paycheck. Under Cal. Fam. Code § 5206, earnings subject to a withholding order include wages, salary, bonuses, commissions, independent contractor payments, interest, dividends, rents, royalties, and workers' compensation temporary disability benefits — essentially any payment due regardless of source.
This expansive definition means support enforcement reaches income that many payors assume is protected. A business that hires an independent contractor with an active IWO must withhold from those contractor payments, not just traditional W-2 wages. Bonuses, commissions, severance pay, retroactive raises, and vacation payouts all fall within the garnishable category under Cal. Fam. Code § 5206. For a payor with variable income, this broad reach prevents structuring compensation as bonuses or contractor fees to dodge support obligations. The breadth of the definition is one reason automatic wage deduction for child support in California is so effective: there are few categories of regular income an income withholding order cannot capture, which closes loopholes that once let high earners minimize garnished wages for alimony or child support.
Employer Duties and Deadlines
Employers in California must begin withholding within 10 days of receiving an Income Withholding Order and remit payments to the State Disbursement Unit within seven working days of each pay date. Under Cal. Fam. Code § 5234, the employer must also give the employee a copy of the order and a Request for Hearing form (FL-450) within 10 days.
Employer compliance is legally mandatory and carries personal liability for failure. An employer who willfully fails to withhold and forward support may be personally liable for the unpaid amount and can be held in contempt of court. To offset administrative costs, the employer may deduct $1.50 from the employee's earnings for each payment processed, in addition to the support amount itself. California also protects employees from retaliation: an employer cannot fire, discipline, or refuse to hire someone because of a child support withholding order. Once an income withholding order is served, the employer must honor it for as long as the employee remains employed, and the obligation does not end when the employee changes jobs — a new employer must begin withholding upon service of a fresh IWO. These rules make employers a reliable, enforced link in the support enforcement wage chain.
Priority When Multiple Garnishments Exist
When an employer holds multiple support orders against one worker, California applies a strict priority sequence under Cal. Fam. Code § 5238: current child support first, then current spousal support, then child support arrears, then spousal support arrears. Support garnishment also takes priority over nearly all other wage attachments.
The priority rules determine who gets paid first when a paycheck cannot satisfy every claim. If the available funds are insufficient to cover all current support orders, the employer prorates the money across each order in proportion to what each requires. Support orders outrank ordinary creditor garnishments, consumer debt judgments, and most other income attachments. The one notable exception involves federal tax liens: an IRS lien served before the support order was entered can take priority, but otherwise federal and state law require child support withholding to come ahead of all other income attachments. This priority structure ensures that garnished wages for alimony and child support are protected from competing creditors, so a divorced parent's support does not get diluted when the payor accumulates other debts subject to wage garnishment.
Enforcement When Garnishment Is Not Enough
When an Income Withholding Order alone cannot collect what is owed, California courts deploy additional enforcement tools including bank levies, property liens, contempt of court, license suspension, and tax refund interception. Unpaid support accrues 10% annual interest under Code of Civil Procedure § 685.010, and arrears exceeding $2,500 trigger federal passport denial.
For a self-employed payor or one whose income is hidden, wage garnishment may not capture the full obligation, so courts turn to broader remedies. A recipient first establishes the arrears amount by filing a Request for Order (Form FL-300) asking the judge to determine arrears and set a monthly payment. Once established, arrears can be collected through bank account levies, real property liens that block sale or refinancing until paid, and interception of federal tax refunds routed through the State Disbursement Unit. In serious cases, California may suspend a payor's driver's license. Contempt of court is the most severe remedy: under California law, a payor who willfully refuses to obey a support order can face fines of up to $1,000 per act, mandatory community service, or up to five days in jail per count. Support violations carry a three-year statute of limitations from the first missed payment.
Modifying or Terminating a Wage Garnishment Order
A California Income Withholding Order does not stop automatically when support ends — the payor or recipient must file an Ex Parte Application to Modify or Terminate an Earnings Assignment Order (Form FL-430). Until a court issues an updated order, the employer must continue deducting support from the paycheck even after a child turns 18.
Many payors mistakenly believe garnishment ceases on its own when a child reaches adulthood or when arrears are paid. It does not. While the obligation for current child support typically ends when a child turns 18 and graduates high school (or 19 if still enrolled), the income withholding order remains in force until a court formally terminates it. If any arrears or accrued interest remain, garnishment continues until those balances reach zero. To stop or reduce the deduction, the payor files Form FL-430, checks the appropriate box to modify or terminate, and serves the updated order on the employer. A payor whose earnings assignment includes arrears payments may also petition to lower the monthly arrears amount. Earnings assignments can additionally be stayed by mutual agreement of both parties, though any stay reverses automatically if the payor later misses payments.
Filing Costs and Residency for the Underlying Divorce
The California divorce that produces a support order costs $435 to $450 to file, and residency requires six months in the state plus three months in the county under Cal. Fam. Code § 2320. As of January 1, 2026, Senate Bill 1427 lets agreeing couples file a Joint Petition (Form FL-700) for a single $435 fee, eliminating service of process.
Garnishment cannot exist without an underlying support order, which originates in a divorce or parentage case. The standard petition filing fee ranges from $435 to $450 depending on the county, and a responding spouse pays a separate $435 — bringing combined fees to roughly $870 when both parties file. As of June 2026, these are the prevailing amounts; verify with your local clerk, because each Superior Court sets its own schedule. Fee waivers are available under Form FW-001 for households at or below 125% of the federal poverty guidelines or receiving benefits like CalWORKs or Medi-Cal. The 2026 SB 1427 joint petition is a significant cost-saver for uncontested cases. California also imposes a mandatory six-month-and-one-day waiting period under Cal. Fam. Code § 2339 before any divorce — and the support order within it — becomes final.
