When child support is not paid, the financial impact on the receiving parent and child can be significant. Washington law provides several enforcement mechanisms to collect unpaid support and encourage compliance with court orders. Whether enforcement occurs through the court system or the Washington State Department of Child Support, unpaid child support can lead to serious legal and financial consequences.
Understanding the available enforcement options can help parents decide how best to respond when support payments stop.
Child Support Becomes a Judgment
In Washington, each unpaid child support payment generally becomes a judgment by operation of law once it becomes due. This means the unpaid amount can be collected through various legal processes, often with interest continuing to accrue over time.
Because arrears become enforceable judgments, unpaid support does not simply disappear if ignored.
Working with the Washington State Department of Child Support (DCS)
One of the most common enforcement tools is through the Washington State Department of Child Support (DCS). DCS has broad administrative authority to collect unpaid support without requiring the receiving parent to file repeated court motions.
DCS enforcement typically starts by looking at wage garnishment, but there are other options available depending on the circumstances. Because DCS has ongoing administrative enforcement powers, many parents find it helpful to open a case with the agency when arrears begin accumulating.
Motions to Enforce Child Support Orders
A parent can also seek enforcement directly through the court by filing a motion to enforce the child support order. This asks the court to compel compliance and may result in payment deadlines, judgments for arrears, or other enforcement remedies.
Enforcement motions are often appropriate when there is a clear payment history showing missed or partial payments.
Motions for Contempt
In more serious cases, a parent may file a motion for contempt. Contempt proceedings allege that the non-paying parent has willfully violated a court order. If the court finds contempt, it may impose sanctions designed to force compliance.
Possible consequences can include:
- Payment plans
- Attorney’s fees
- Fines
- Additional enforcement conditions
- In extreme cases, though typically unlikely, jail sanctions
Courts typically examine whether the parent had the ability to pay but failed to do so voluntarily.
What If You Owe Child Support Arrears?
If you are behind on child support, ignoring the issue usually makes matters worse. Interest may continue to accrue, and enforcement actions can escalate quickly. If your financial circumstances have changed, you may need to seek a modification or adjustment of future support obligations, although this generally does not erase existing arrears. Proactively communicating, entering payment arrangements, or addressing the issue early can sometimes reduce the likelihood of more severe enforcement measures.
Washington provides multiple enforcement tools for unpaid child support, ranging from administrative collection through DCS to court-based enforcement and contempt proceedings. Understanding these options can help parents protect their rights and address support issues effectively.
