Can Child Support Arrears Be Forgiven in California?

Direct answer

Usually not by a judge alone. In California, a court generally cannot reduce child support that came due before a request to modify was filed. Past-due support can shrink in narrower ways. Debt owed to the state may be compromised through a state program. The parent who is owed support can agree to accept less.

Overview

Most people facing this question are standing on one side of a growing number. One parent may have lost a job, fallen behind, and watched the balance and the interest keep climbing in San Diego County. The other parent may have waited months or years for money that was ordered and never paid, and now wonders whether the debt can quietly vanish. Both are trying to learn the same thing: what California law actually allows, and what it does not.

This explainer walks through what arrears are, the rule that blocks a court from erasing them, the state compromise program, what the parent who is owed can and cannot do, how long the debt stays enforceable, and how enforcement works when a support case has become contested.

What Child Support Arrears Are Under California Law

Arrears are past-due, unpaid child support. They are the amounts a court order required and that were not paid when due. Current support is the monthly amount owed going forward. Arrears are the total of the months that were missed.

That difference matters more than people expect. A parent can be fully up to date on this month's payment and still owe a large arrears balance from earlier years. Changing the current order does not, by itself, touch that older balance.

California generally treats each unpaid installment as a judgment once it falls due. A judgment is a court's final, enforceable money ruling. That is why a missed payment does not stay a missed payment. It becomes a debt that carries the force of a court judgment, with collection tools behind it.

Interest is part of the picture. Under Code of Civil Procedure section 685.010, interest generally accrues at 10 percent per year on the unpaid principal of a money judgment. The reduced 5 percent rate in that section applies only to certain medical and personal-debt judgments. Over several years, interest can become a meaningful share of what is owed.

Who the money is owed to also matters. Some arrears are owed to the state, typically because public aid was paid for the child and the state seeks reimbursement. These are often called assigned arrears. Other arrears are owed directly to the parent who was supposed to receive the support. These are often called unassigned arrears. As the sections below explain, the options for reducing each kind are different.

In San Diego County, an order may be enforced through the local child support agency when the case is in its caseload, or through a private request filed in the Superior Court of California, County of San Diego.

If this is happening in your case, the next steps can affect what evidence is available later.

The Short Answer: What California Law Allows — and Does Not Allow

The governing rule sits in Family Code section 3651. Subdivision (c)(1) reads:

"Except as provided in paragraph (2) and subdivision (b), a support order may not be modified or terminated as to an amount that accrued before the date of the filing of the notice of motion or order to show cause to modify or terminate."

In plain terms, a judge generally cannot go back and lower support that came due before someone formally asked the court for a change. A notice of motion, or an order to show cause, is the court filing that asks for that change. One narrow exception in the statute concerns a parent activated to military duty and deployed out of state, a topic covered elsewhere.

The companion rule is Family Code section 3653(a). It allows a modification to reach back to the date the request was filed, or any later date, subject to the exceptions in that section and federal law. Together, these two sections draw a hard line at the filing date. Months before it are generally fixed. Months after it are open to change.

So two different questions often get blended together. One is whether a court can lower support from the filing date forward. Often it can, if the facts support a change. The other is whether accrued arrears can be erased. That is far more limited.

There is no blanket forgiveness program in California. What exists is narrower and depends on who holds the debt:

  • For arrears owed to the state, a statewide compromise program may accept a reduced payment.
  • For arrears owed to the other parent, the reduction runs through that parent's agreement.

For a parent who has been carrying this debt for a while, the filing-date rule is often the most important single fact in the case. Many people do not learn it until the months they hoped to change have already locked in.

The Compromise of Arrears Program (COAP)

Family Code section 17560 directs the state to run a statewide compromise of arrears program. Under that program, the state may accept offers in compromise of child support arrears, and interest on them, that are owed to the state as reimbursement for public aid paid for the child. An offer in compromise is a proposal to settle the debt for less than the full balance.

The statute sets out how the program works, including these points:

  • It operates uniformly across California. It must consider the needs of the children covered by the order and the paying parent's ability to pay.
  • Current support comes first. If the parent still owes current support, the offer requires a set period of compliance with the current order before any arrears or interest can be compromised.
  • Honesty is a condition. Absent good cause, or a determination by the director that the state's best interest calls for a different result, the compromise is rescinded if the parent concealed income, assets or other property, falsified records, or made false statements about finances. All compromised amounts are then reestablished, notwithstanding any statute of limitations that might otherwise apply, and nothing paid is refunded. The same consequence follows if the parent fails to meet the compromise's terms.
  • The other parent's share is protected. The department may not accept a compromise of arrears owed directly to the custodial parent unless that parent consents in writing and takes part in the agreement.

That last point is the key limit. The program is built for debt owed to the state. Arrears owed directly to the other parent stay that parent's money, and they remain enforceable unless that parent agrees in writing to something different.

Access runs through the local child support agency. Current program details, applications and eligibility information are posted on California's official child support website and on San Diego County's child support agency page.

Unassigned Arrears: What the Custodial Parent Can and Cannot Do

Arrears owed directly to the custodial parent belong to that parent, not the state. That is why the parent who is owed the money is the person who can agree to accept less.

Section 3651(c) still limits the court. A paying parent's request alone does not authorize a judge to erase arrears that came due before the filing date. Nothing in that rule, though, prevents the parent who is owed from choosing to compromise what is owed to them.

When parents do reach that kind of agreement, the practical concern is proof. Parents in this position typically put the terms in writing and present the agreement to the court so it becomes part of the court's record. An informal understanding, or a conversation years ago, leaves the debt's status uncertain. The underlying judgment amounts may also still appear on enforcement records if the agreement was never put before the court.

Interest raises its own questions in any agreement, including whether accrued interest is included or waived. How a court treats a particular agreement depends on its terms and the facts, which is one of the issues a family law attorney looks at closely.

Disputes about the balance itself are common in contested support cases. One parent may say payments were made in cash or directly. The other may say they were not. Bank records, payment histories and sworn financial disclosures are the usual evidence. When a dispute centers on undisclosed earnings, the methods for proving hidden income come into play, including discovery and subpoenas.

Is There a Statute of Limitations on Child Support Arrears in California?

Code of Civil Procedure section 683.020 sets the general rule for ordinary money judgments. Except as otherwise provided by statute, once 10 years pass after entry, the judgment may not be enforced, enforcement procedures stop, and liens created by enforcement are extinguished.

Child support is one of the situations covered by that "except as otherwise provided" language. Family Code section 4502 provides that the period for enforcement, and the procedure for renewal, of a judgment or order for child, family or spousal support is governed by Family Code section 291. Support judgments are not simply left to the ordinary 10-year clock.

The practical point is the one that matters most to both parents. Child support arrears in California do not simply disappear after 10 years. Waiting is not a forgiveness mechanism. A time limit on enforcement, where one applies, is a different thing from a debt being forgiven.

Agency enforcement also runs on its own track. The compromise program described above, for example, reestablishes compromised debt when the compromise is rescinded, notwithstanding any statute of limitations that might otherwise apply.

How Arrears Are Enforced in San Diego County

When the local child support agency enforces a case, it has statutory tools that a private parent may not have on their own. Family Code section 17523 provides that when a paying parent is delinquent, meaning they have failed to pay an amount equal to one month's support, and the local agency is enforcing the case, a child support lien arises against the parent's personal property. The lien is perfected by filing a notice with the Secretary of State. It then has the same priority, force and effect as a judgment lien on personal property.

The earnings assignment is the workhorse of support enforcement. Under Family Code section 5230, when a court orders support or modifies it, the order must include an earnings assignment directing the employer to pay the receiving parent enough of the paying parent's earnings to cover both current support and an amount the court orders toward any arrearage. The assignment issues even if the employer's name and address are not yet known.

The local agency uses additional collection tools beyond these. The county's child support agency page describes how its cases are handled. A paying parent who disputes the balance can raise the question with the agency or bring the issue before the court.

Cases outside the agency's caseload are enforced privately in the Superior Court of California, County of San Diego. Contested support enforcement can involve evidence of what was paid, sworn financial disclosures and, in some cases, contempt. Contempt is a court finding that a person willfully disobeyed a court order, and contempt in family court has its own elements and procedure. The broader landscape of post-judgment disputes covers when an order is better modified and when it is better enforced. The self-help resources from the California courts explain the general filing steps for support requests.

For a parent who has been waiting on unpaid support, enforcement is the part of the law that turns an order on paper into money. For a parent who owes, it is often the part that makes the debt impossible to ignore.

What the 2024–2026 Child Support Law Changes Mean for Arrears

California's guideline formula appears in Family Code section 4055. The formula, CS = K[HN − (H%)(TN)], uses each parent's net monthly disposable income, the high earner's share of parenting time, and a factor that varies with total household income. The section has been updated in recent years.

A formula change looks forward. It governs how support is calculated when a court sets or modifies an order. It does not reach back and recalculate months that have already come due. Section 3651(c) limits a modification to amounts from the filing date forward, and section 3653(a) allows a modification to reach back no further than that date.

A parent whose current order was set under an earlier version of the formula may ask the court to modify prospective support, the payments still to come, under the current guideline. If the court lowers the order, section 3653(d) says the paying parent may be entitled to repayment of amounts paid above the new figure for the retroactive period, according to the order's terms. The arrears balance from before the filing date stays where it was. How guideline support is set and contested is covered in more depth on the page about child and spousal support disputes.

No California legislation as of this article's review date creates a general arrears forgiveness program beyond the compromise program for arrears owed to the state. Laws change. Any newer legislation can be checked at California's official child support website or on the California Legislative Information site. This article reflects the law as of the date reviewed.

If You'd Like to Talk Through an Arrears Problem

Arrears cases turn on details that are easy to miss: who holds the debt, when a modification request was filed, what was actually paid, and whether any agreement between the parents was ever put before the court. A consultation is the place to walk through the order, the payment history and the enforcement steps already taken, and to understand which rules apply to the balance and which months may still be open to change.

Questions

Frequently asked questions

How do I get rid of child support arrears in California?

No single path eliminates arrears. Debt owed to the state may be reduced through the statewide compromise program under Family Code section 17560, which looks at the children's needs and the paying parent's ability to pay. Arrears owed to the other parent can be reduced only with that parent's agreement, because Family Code section 3651(c) generally bars a court from modifying amounts that accrued before a modification request was filed.

Is there a statute of limitations on child support arrears in California?

Not in the way most people assume. Ordinary money judgments generally become unenforceable 10 years after entry under Code of Civil Procedure section 683.020, but that section yields where another statute provides otherwise. Family Code section 4502 sends child support enforcement and renewal to Family Code section 291, and arrears do not simply disappear after 10 years.

What is the child support arrears forgiveness program in California?

It is the statewide compromise of arrears program under Family Code section 17560. It may accept a reduced payment on arrears and interest owed to the state as reimbursement for public aid. It cannot compromise arrears owed directly to the other parent unless that parent consents in writing and takes part. Current details are posted at childsupport.ca.gov.

Can a judge forgive child support arrears in California?

Generally not on a paying parent's request alone. Family Code section 3651(c) bars a court from modifying or terminating support as to amounts that accrued before a modification request was filed, with a narrow exception for certain deployed servicemembers. A court can change support from the filing date forward when the facts support it.

What happens to child support arrears if the custodial parent agrees to forgive them?

The parent who is owed unassigned arrears is the person who can agree to accept less, because that money belongs to them. An informal understanding leaves the debt's status uncertain. Parents in this situation typically put the terms in writing and present the agreement to the court so it becomes part of the record.

Does the new 2024 child support guideline in California reduce existing arrears?

No. The guideline formula in Family Code section 4055 governs how support is calculated when an order is set or modified going forward. A parent may ask the court to modify current support under the formula, but sections 3651(c) and 3653(a) limit any change to the filing date forward.
