Back Child Support in Wyoming: What You Need to Know (2026)

Back child support in Wyoming is past-due child support, also called child support arrears or child support debt, that a parent owes after missing court-ordered payments. Wyoming charges a 10% penalty on missed payments and 10% annual interest on amounts reduced to judgment under Wyo. Stat. § 20-2-308, and the state imposes no statute of limitations on collecting these debts. The Wyoming Department of Family Services (DFS) Child Support Program enforces arrears through wage garnishment, tax interception, license suspension, property liens, and passport denial.

This guide explains how back child support Wyoming cases work in 2026, including how arrears accrue, how judgments form, every enforcement tool the state can use, when support ends, and how to address a child support debt you cannot pay. The information reflects Wyoming Statutes Title 20 (Domestic Relations) and the Wyoming Child Support Program Policy Manual.

Key Facts: Back Child Support in Wyoming

What Counts as Back Child Support in Wyoming?

Back child support in Wyoming is any court-ordered child support payment that remains unpaid on its due date, accumulating as child support arrears. Each missed installment becomes a separate debt the moment it goes unpaid, and Wyoming adds a 10% penalty on the current missed obligation plus 10% annual interest once the unpaid amount is reduced to a money judgment under Wyo. Stat. § 20-2-308.

Wyoming distinguishes between two types of arrears. The first is past-due support owed directly to the custodial parent for the child's benefit. The second is assigned arrears owed to the State of Wyoming, which arise when the custodial family received public assistance (such as POWER benefits) and the state stepped in to support the child. The District Child Support Program attorney cannot negotiate or waive assigned arrears owed to the State without written permission from the IV-D Director, making state-owed debt significantly harder to reduce than debt owed to a private custodial parent.

A practical example shows how fast child support debt grows. A parent who misses a $500 monthly payment for six months accumulates $3,000 in unpaid principal, plus roughly $150 in penalties and statutory interest, escalating the total obligation well beyond the original amount due.

How Are Arrears Reduced to a Judgment in Wyoming?

In Wyoming, each unpaid child support installment automatically becomes a separate money judgment by operation of law, with no hearing required. The Wyoming Supreme Court has held that a decree for periodic child support creates sequential judgments enforceable under the standard judgment-enforcement statutes, meaning every missed payment functions as its own enforceable judgment rather than a single statute-based liability.

This judgment-by-operation-of-law structure has major consequences for collection timing. Under Wyo. Stat. § 1-17-307, a judgment becomes dormant if no execution occurs within five years. However, a dormant child support judgment remains revivable for up to 21 years, and revival happens when the State or the custodial parent files a motion to enforce. Because of this revival window, parents cannot simply wait out a child support debt in Wyoming.

When the District Child Support Program office files an action to enforce or modify an order against an obligor who is behind, the District attorney requests a formal judgment on the arrears. Wyoming court packets are titled "Petition for Modification of Child Support and Judgment for Arrears (If Any)," so a single court proceeding can both adjust the going-forward obligation and reduce existing past due child support to an enforceable judgment.

Is There a Statute of Limitations on Back Child Support in Wyoming?

Wyoming imposes no statute of limitations on collecting back child support, and courts may enforce past-due support even after the child turns 18 or becomes emancipated. Because each unpaid installment is treated as a sequential money judgment subject to a 21-year revival period rather than a statute-based claim, arrears do not expire the way ordinary debts do.

This distinguishes child support arrears from most civil debts in Wyoming. While a judgment goes dormant after five years without execution under Wyo. Stat. § 1-17-307, that dormancy does not extinguish the debt; it merely requires a revival motion before the state can execute again. The State of Wyoming routinely files such motions to revive dormant child support judgments on behalf of custodial parents, which means a child support debt can remain collectible for decades after the underlying order was entered.

One related deadline applies to paternity rather than arrears collection. A paternity action in Wyoming must generally be brought within three years after the child reaches the age of majority if filed by the child or the State. Once paternity and a support obligation are established, however, the resulting arrears carry no collection deadline, and the owing parent remains liable until the full child support debt is satisfied.

How Does Wyoming Enforce Back Child Support?

Wyoming enforces back child support through the DFS Child Support Program, which can garnish wages, intercept tax refunds, suspend licenses, place liens on property, deny passports, and pursue contempt of court. Most administrative remedies require no court hearing, allowing the state to act quickly against an obligor who owes child support.

Income withholding is the primary tool. Wyoming employers are legally required to deduct ordered child support directly from a paying parent's paycheck, including amounts allocated toward arrears. When wages are insufficient, the state escalates to additional federal and state collection mechanisms layered on top of withholding.

The table below summarizes Wyoming's main enforcement tools and the thresholds that trigger them:

When a parent willfully refuses to pay, the District Court can hold them in contempt and impose fines or jail time. Bank levies and seizure of state welfare benefits provide further collection avenues against persistent past due child support.

How Do Property Liens Work on Wyoming Child Support Debt?

Wyoming places an automatic lien on a delinquent parent's real and personal property once their child support arrears reach three times the monthly support obligation. Under Wyo. Stat. § 20-6-106, the Department of Family Services holds a lien by operation of law against property owned by an in-state obligor, and it must perfect and enforce that lien when arrears hit the triple-obligation threshold.

For a parent ordered to pay $500 per month, the lien obligation activates at $1,500 in unpaid support, equal to three months of missed payments. The department perfects the lien in the same manner used for the specific type of real or personal property involved, attaching to homes, vehicles, bank accounts, and other assets. Lien priority dates from the date of filing or perfection when competing encumbrances exist on the same property.

Wyoming also honors out-of-state child support liens. The state accords full faith and credit to a child support lien arising in another state, provided that lien was properly filed and recorded under the other state's laws. This interstate cooperation means a parent who moves to Wyoming cannot escape a lien properly established elsewhere, and Wyoming property remains exposed to collection for child support debt originating in another jurisdiction.

Can Wyoming Deny My Passport for Back Child Support?

Yes. Wyoming certifies parents who owe more than $2,500 in child support arrears to the federal Passport Denial Program, which blocks them from obtaining or renewing a U.S. passport. Wyoming is a zero-tolerance state, meaning a parent must pay the entire arrears balance in full, not merely drop below the threshold, before a denied passport is released.

The $2,500 figure comes from federal law. The Passport Denial Program originated in the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 at a $5,000 threshold, which the Deficit Reduction Act of 2005 lowered to $2,500. States certify qualifying parents, the federal Office of Child Support Services forwards the names to the U.S. Department of State, and the State Department then denies the passport application.

Wyoming follows strict procedural requirements before certification. The Wyoming Child Support Program must notify the non-custodial parent at least 30 days before certifying them to the Passport Denial Program and must confirm the arrears balance exceeds $2,500. This notice is typically consolidated with other federal offset notifications, including the tax refund offset. One important limit applies: when Wyoming acts as the responding state in an intergovernmental case, it will not submit the non-custodial parent for passport denial.

How Does the Federal Tax Offset Apply to Wyoming Arrears?

Wyoming intercepts federal and state tax refunds through the Treasury Offset Program (TOP) to satisfy child support arrears, submitting non-assistance cases with arrears over $500 and public assistance cases with arrears over $150. The IRS matches a filer's Social Security Number against the TOP database and redirects refunds to past-due support before the parent receives any remaining balance.

Wyoming credits the non-custodial parent with the entire intercepted amount, but it retains a $25 federal tax offset fee from collections made on behalf of a non-public-assistance custodial parent, except in foster care or POWER cases. Only IV-D cases (those managed through the state child support program) may be submitted for federal offset, so privately enforced orders not in the IV-D system are not eligible for tax interception.

The offset operates independently of passport denial, though both are triggered by accumulating child support debt and noticed together at least 30 days in advance. A parent receiving a TOP notice should review the stated arrears balance carefully, because both spouses' refund can be affected on a joint return, and the non-owing spouse may need to file an injured-spouse claim with the IRS to recover their share. Even if arrears later fall below the threshold, a parent may not be automatically removed from these federal programs.

When Does Child Support End in Wyoming, and What Happens to Arrears?

Child support in Wyoming ends when the child turns 18, or up to age 20 if the child is enrolled full-time in high school, and continues indefinitely for a child with a disability who cannot self-support. Ending the ongoing obligation, however, does not erase any back child support already owed.

Support also terminates earlier upon emancipation. A child support obligation ends if the child dies, marries, joins the military, or is legally emancipated by court order. The age of majority for support purposes is 18 unless the high-school or disability exceptions apply, per Wyoming Judicial Branch guidance and Wyo. Stat. § 14-1-101.

The Wyoming Child Support Program Policy Manual is explicit that arrears survive termination. If a termination order or adoption decree is silent about arrears, the child support arrears that accrued under the prior order remain due and owing, and the Wyoming Child Support Program will continue to enforce them under state and federal law. One narrow exception exists: if the child's parents marry or remarry each other, the District Court may eliminate arrears that accrued under the previous order, except for any arrears owed to the State of Wyoming, which can never be eliminated through remarriage.

Can Back Child Support Be Reduced or Forgiven in Wyoming?

Wyoming generally prohibits retroactive reduction of child support arrears, and under Wyo. Stat. § 20-2-311 a support order may only be modified back to the date the other parent was served with a modification petition. Arrears that accrued before that service date remain legally owed, so a parent cannot retroactively wipe out a child support debt that has already built up.

Going-forward modification is possible when circumstances change. A parent may petition for review and adjustment of an order entered more than six months earlier, alleging that the presumptive guideline amount would change the obligation by 20% or more per month. Separately, every three years either parent (or the department, when support rights are assigned) may request a review and adjustment without showing changed circumstances. Acting promptly matters, because any reduction applies only from the date of service forward, never to existing arrears.

Full forgiveness of arrears is rare and difficult. Arrears owed to the State of Wyoming cannot be negotiated or waived without written permission from the IV-D Director. A parent unable to pay because of disability or another hardship may file a motion addressing the debt, but courts treat arrears dismissal as exceptional. The most reliable strategy is to file for modification immediately when income drops, preventing new unpayable arrears from accruing.

How Do I Address Back Child Support I Cannot Pay in Wyoming?

A parent who cannot pay child support in Wyoming should immediately file a petition to modify the order through the District Court or the DFS Child Support Program, because reductions apply only from the date the other parent is served, never retroactively to existing arrears under Wyo. Stat. § 20-2-311. The filing fee for a child support modification is $160 as of January 2026 (verify with your local clerk).

Wyoming provides free self-help resources to make filing accessible. The Wyoming Supreme Court publishes downloadable forms at no cost, with Packet 7 used to request a change in child support and Packet 8 used to respond to a petition you receive. A parent who cannot afford the $160 fee may file the Wyoming Affidavit of Indigency and Request for Waiver of Filing Fees (in forma pauperis). Every modification requires a financial affidavit on the Supreme-Court-approved form, supported by pay stubs, employer statements, or self-employment records plus the most recent tax return, as required by Wyo. Stat. § 20-2-308.

Legal help is available at varying cost levels. Wyoming permits limited-scope representation, so an attorney may assist with only the forms rather than the full case, and the Wyoming State Bar Lawyer Referral Service (307-632-9061) maintains a list of attorneys offering this service. Full attorney representation for a straightforward child support matter is commonly estimated at roughly $2,500 to $5,000, though actual fees vary widely by county and complexity. Acting quickly is the single most effective step, since delay only allows the child support debt to grow under Wyoming's 10% penalty and interest provisions.
