What Is URESA? UIFSA Replacement and Interstate Enforcement

URESA, the Uniform Reciprocal Enforcement of Support Act, no longer governs interstate child support enforcement in any state. It was replaced by the Uniform Interstate Family Support Act (UIFSA), which every state has adopted as a condition of receiving federal child support funding.¹ UIFSA covers both child support and spousal support, and it is the law your local child support agency uses when the other parent lives in a different state.

Why URESA Was Replaced

URESA dates to 1950 and was revised several times, but it had a structural flaw: multiple states could issue competing support orders for the same family.² A parent could face conflicting payment amounts from different courts, and custodial parents sometimes had to chase enforcement in several places at once.

UIFSA, first drafted in 1992, built the system around a one-order-at-a-time rule. Only one state holds authority to issue and modify a support order at any given moment. Congress required states to adopt UIFSA by January 1, 1998, and later required adoption of the 2008 amendments that align the law with the Hague Convention on international child support.¹

Which State Controls the Order

The state that issued the support order keeps exclusive authority to modify it as long as the paying parent, the receiving parent, or the child still lives there. No other state can change the amount while that connection exists. This blocks a parent from moving to a new state and asking a new court to lower the obligation.

When everyone has left the issuing state, that state loses its exclusive jurisdiction. A new state can then take over if both parties agree in writing, or if the party seeking a change files in the state where the other party now lives.

For a brand-new order, UIFSA’s long-arm provisions often let the custodial parent’s state reach a nonresident parent without anyone traveling. Grounds include the nonresident parent having previously lived in the state with the child, having supported the child while living there, having engaged in conduct in the state that may have resulted in the child’s conception, being personally served while present in the state, or voluntarily appearing in the case.

Opening an Interstate Case

Interstate enforcement runs through your local Title IV-D child support agency. Before the agency can act, you need to supply as much information about the other parent as you can: full legal name, aliases, Social Security number, date of birth, current or last-known address, and employer name and address. Employer information matters because it lets the agency pursue wage withholding immediately.

If the other parent has moved or is hiding, agencies use the Federal Parent Locator Service to cross-reference federal records for addresses and employment data.³ The more identifying detail you provide upfront, the faster that search works.

The paperwork uses standardized federal forms that every state must accept.⁴ The core document is the Uniform Support Petition, which formally asks the responding state to act. You will also need certified copies of any existing support orders, divorce decrees, or paternity acknowledgments. A certified copy carries an official court seal; the responding state will not enforce an order without one. If back support is owed, expect to file a sworn statement with the exact arrears amount, including any interest or penalties. Missing or inaccurate documents are a common reason interstate cases stall.

What Happens After You File

Your local office reviews the package and forwards it to the Central Registry of the state where the other parent lives. Federal law requires every state to run a Central Registry that receives incoming interstate cases and routes them to the right local office.⁵

The responding state then takes over. Its agency serves the other parent with notice, which may be a formal summons or a notice of wage withholding. The parent typically has several weeks to respond before a default order can be entered. If a hearing is needed, it is often held by phone or video so neither party has to travel.

In most cases, the responding state issues an income withholding order sent directly to the other parent’s employer. Federal law requires immediate income withholding on all new and modified support orders.¹ Collected funds move through the responding state’s payment processing system to your state’s disbursement unit. Expect some lag between when the employer receives the order and when payments start arriving.

Enforcement Tools That Reach Across State Lines

The federal enforcement toolkit works automatically across state lines, which is what makes it effective against parents who relocate.

Income withholding. The backbone of collection. Employers must honor withholding orders from other states, up to the limits set by the Consumer Credit Protection Act.¹
Passport denial. When arrears exceed $2,500, the state can certify the debt to the federal government, which directs the State Department to refuse, revoke, or restrict the parent’s passport.⁶
Tax refund interception. The Treasury Offset Program matches parents who owe arrears with federal payments like tax refunds and applies the money to the debt.⁷
License suspension. States must have procedures to suspend driver’s, professional, and recreational licenses when a parent owes overdue support or ignores related court orders.¹
Property liens. Overdue support automatically creates liens against real and personal property, and states must honor liens from other states.¹
Credit reporting. Agencies can report overdue support to consumer reporting agencies, where it can stay on the parent’s credit report for up to seven years.

Courts can also hold a nonpaying parent in civil contempt, which can carry jail time. Contempt is generally used as a last resort when other tools have failed and the parent has the ability to pay but refuses.

Modifying an Order Issued in Another State

If at least one party still lives in the state that issued the original order, that state keeps exclusive authority over modifications. You file there, even if you have moved, and that state’s court uses its own guidelines to recalculate support.

If everyone has left the issuing state, either party can seek a modification in the state where the other party now lives, provided that state can exercise personal jurisdiction over them. The parties can also agree in writing to let a specific state handle the change.⁸ The new state then holds continuing exclusive jurisdiction going forward.

One hard limit: no state can retroactively reduce support that has already come due. Each missed payment becomes a judgment by operation of law the moment it is due, carrying the full force of any other court judgment.¹ A modification only changes future payments.

When Older Cases Left More Than One Order

Some URESA-era cases produced competing orders from different states. UIFSA has a process for sorting them out. If only one state ever issued an order, that order controls. If multiple orders exist, the order from the state where the child currently lives generally takes priority. When neither the child nor the parties live in any of the issuing states, the most recent order usually controls.⁹

Once the controlling order is identified, the others matter only for calculating arrears that built up while they were in effect. If you may be dealing with more than one order, raise it with your caseworker early so the determination happens before enforcement creates confusion.

If the Other Parent Is in Another Country

UIFSA is for interstate cases, but it also handles international ones through the 2007 Hague Convention on the International Recovery of Child Support, which entered into force for the United States on January 1, 2017.¹⁰ For Convention countries, you work through the same child support agency that handles domestic interstate cases, and each country operates a Central Authority that transmits and receives applications.¹¹ For non-Convention countries, enforcement depends on whether the United States has a separate bilateral agreement, and the process is significantly harder.

What It Costs

Services from a Title IV-D agency are inexpensive. States may charge a one-time application fee of up to $25 for cases that are not on public assistance. Federal law also requires a $35 annual service charge on cases where the family never received public assistance and the state has collected at least $550 in support that year.⁵ The fee is typically deducted from collected support rather than billed separately.

Beyond agency fees, budget for certified copies of court documents, which cost anywhere from a few dollars to around $40 depending on your local court clerk. If the other parent needs personal service, process server fees vary by jurisdiction. The IV-D agency handles most of the legal work at no additional cost.
