California can garnish a child's SSDI or SSI payments for child support, but only under specific conditions and with limits that protect the child's basic needs.

When a parent owes child support, California's Department of Child Support Services can pursue collection from many income sources—including disability payments made to a minor child. However, federal law and California state law both place restrictions on how much can be taken and what counts as income available for garnishment. The rules differ depending on whether the child receives SSDI (Social Security Disability Insurance) or SSI (Supplemental Security Income), and whether the debt is current or past-due.

The key distinction is that SSI is a needs-based program designed to keep recipients above poverty, so California's power to garnish it is narrower than its power to garnish SSDI. Both programs are federal, but state child support agencies have been given authority to reach them under federal law—with guardrails.

Key Takeaways

  • California can garnish SSDI payments for child support, but only up to 50% of the monthly benefit if support is current, or up to 65% if support is past-due by more than 12 months.
  • SSI payments are much harder to garnish because SSI is a poverty-level benefit; California can only take SSI if the child has other income or resources that make them ineligible for the full SSI amount anyway.
  • The child support obligor (the parent who owes) can request a hearing to argue that garnishment would cause undue hardship, but the burden is on them to prove it.
  • Garnishment orders must be served on the Social Security Administration directly; payments do not stop automatically when a child support debt arises.
  • If the child is in foster care or receiving CalWORKs, the state may already be collecting child support on the child's behalf, which affects how much additional garnishment can occur.

How SSDI Garnishment Works in California

If a child receives SSDI and a parent owes child support, California can issue a garnishment order to the Social Security Administration. The federal Consumer Credit Protection Act sets the ceiling: California can take up to 50% of the monthly SSDI benefit if the support obligation is current (payments are being made on time), or up to 65% if the obligor is more than 12 months behind.

The garnishment applies to the child's own SSDI benefit—the payment based on the child's disability record, not any family benefit the child might receive as a dependent of a working parent. If the child also receives a family benefit (for example, because a parent is retired or deceased), that portion may be subject to different rules and should be clarified with Social Security before the garnishment order is served.

California's Department of Child Support Services must serve the garnishment order on the Social Security Administration's Office of Child Support Enforcement, not on the local Social Security office. Once served, Social Security will begin withholding from the child's next payment. The obligor has the right to request a hearing before the state to challenge the garnishment on grounds of undue hardship, but they must file that request within a set timeframe—usually 10 days from the date they receive notice of the garnishment.

Why SSI Is Harder to Garnish

SSI (Supplemental Security Income) is a federal needs-based program that provides a monthly payment to disabled, blind, or elderly individuals with very limited income and resources. The federal benefit amount in 2024 is set at a level meant to cover only basic living expenses. Because of this, federal law restricts state child support agencies' ability to garnish SSI.

California cannot straightforward take a percentage of SSI the way it can with SSDI. Instead, the state can only garnish SSI if the child has other income or resources that reduce their SSI may be able to access. For example, if the child receives both SSI and a small amount of unearned income (such as interest from a savings account), and that income causes the SSI payment to be reduced, then California can garnish the portion of the child's total income that is not SSI. This is a much narrower window than with SSDI.

In practice, most children receiving SSI have little to no other income, so garnishment is rare. If you believe your child's SSI is at risk of garnishment, contact the local Social Security office to confirm the child's current income and resource situation, and then speak with the Department of Child Support Services about what they can actually reach.

When the State Is Already Collecting on the Child's Behalf

If the child is in foster care or receiving CalWORKs (California's cash information program), the state may already be collecting child support from the obligor on the child's behalf. In these cases, the child support collected goes first to reimburse the state for the cost of foster care or CalWORKs, and any remainder goes to the child or is held in an account for the child.

When the state is already collecting, additional garnishment of the child's disability payment may be limited or coordinated differently. The Department of Child Support Services and the Social Security Administration coordinate to avoid double-collection. If you are unsure whether the state is already collecting on your child's case, contact your local child support office or ask for a case summary.

If the obligor is behind on support and the state is collecting through wage garnishment or other means, the state may still pursue garnishment of disability payments to catch up the arrears. The two collection methods can run in parallel.

How to Challenge a Garnishment Order

If you are the parent owing child support and you receive notice that your child's disability payment will be garnished, you have the right to request a hearing. You must file the request with the Department of Child Support Services within the timeframe stated in the notice—typically 10 days. At the hearing, you can argue that the garnishment would cause undue hardship to you or the child.

Undue hardship is a high bar. It is not enough to say that you cannot afford to pay; you must show that garnishment would prevent you from meeting your own basic needs or the child's basic needs. For example, if the garnishment would leave you unable to pay rent or buy food, or if it would prevent you from paying for the child's medical care or school expenses, you may have grounds. The hearing officer will weigh your circumstances against the amount of the arrearage and the child's needs.

If you lose at the hearing, you can appeal to the superior court, but you must do so within 30 days. An attorney can help you prepare your case, and some legal aid organizations in California offer free or low-cost representation in child support matters.

What Happens to Garnished Money

When Social Security withholds money from the child's SSDI or SSI payment due to a child support garnishment, that money goes to the California Department of Child Support Services, not directly to the obligor or the child. The state then applies the money to the child support debt owed by the obligor.

If the obligor is current on support, the garnished amount reduces future support obligations. If the obligor is behind, the garnished amount is applied to the arrears first, and only after arrears are paid does it reduce current support. The obligor will receive a notice showing how the garnished amount was applied.

The child does not receive the garnished portion of their disability payment. This can create a real hardship if the child's disability payment is their only income and they depend on it for daily expenses. If you are the parent or caregiver of a child whose disability payment is being garnished, you may want to explore whether the child is may have access to to other benefits (such as food information or housing support) that could offset the loss.

Protecting the Child's Disability Payment

If you are concerned that your child's disability payment may be at risk of garnishment, there are a few steps you can take. First, confirm with the Social Security Administration what type of benefit the child receives (SSDI, SSI, or both) and the exact monthly amount. This information is on the child's Social Security statement or award letter.

Second, contact the Department of Child Support Services to find out whether there is an active child support case involving the child and whether any garnishment orders have been issued. You can request a case summary by calling your local child support office or visiting the department's website.

Third, if you are the obligor and you believe you have grounds to challenge a garnishment, gather documentation of your income, expenses, and the child's needs before the hearing. If you are the custodial parent or caregiver, you may want to consult with a legal aid attorney about whether the child's SSI or SSDI is protected in your specific situation.

Frequently Asked Questions

Can California garnish my child's disability payment if I am not behind on support?

Yes, but only up to 50% of the SSDI benefit if support is current. California can garnish even when payments are being made on time. If support is past-due by more than 12 months, the percentage can go up to 65%.

What if my child receives both SSDI and SSI?

Social Security does not typically pay both SSDI and SSI to the same person in the same month; the person receives whichever benefit is higher. However, if your child's situation is unusual, contact Social Security directly to clarify which benefit is being paid and in what amount, because garnishment rules differ.

Can I stop the garnishment by paying the back support?

Yes. If you pay off the entire arrears, California will lift the garnishment order. You must notify the Department of Child Support Services that you have paid, and they will confirm the payoff and send a release order to Social Security. The process can take a few weeks.

Does the child get the garnished money back later?

No. The garnished amount is applied to the obligor's child support debt and does not go to the child. The child loses that portion of their monthly benefit permanently unless the obligor later receives a credit or refund from the state, which is rare.

What if I disagree with the amount of child support I owe?

Disagreement with the support amount is separate from a garnishment challenge. You can request a modification of the support order through the Department of Child Support Services or family court, but that does not automatically stop a garnishment. You should pursue both the modification and the garnishment hearing at the same time.
