Moving out of state with a child support order
By the HowMuchChildSupport team · Published
Parents move for new jobs, family, the military or a fresh start, and a child support order does not stay behind when they do. People who are about to move, or who just have, usually ask the same questions: does the order still count, can the new state change it, whose guidelines apply now, and what happens to the payments?
The short answer is that the order follows the family across state lines, and the state that issued it usually keeps control. This guide walks through what a move changes and what it doesn’t, from both sides: the paying parent and the receiving parent. The technical rules about registering orders and deciding which order controls are covered in the guide to child support across state lines; this one focuses on the practical steps. It is general information, not legal advice.
Your order stays in effect after a move
A child support order is not tied to where a parent lives. Under the Full Faith and Credit for Child Support Orders Act, 28 U.S.C. § 1738B, every state must enforce another state’s child support order according to its terms, and may not change it except under the limits that statute sets. Federal law also requires every state to have the Uniform Interstate Family Support Act (UIFSA) in effect as a condition of its child support program (42 U.S.C. § 666(f)), so the same rules apply wherever a parent goes.
In practice that means:
- Payments keep coming due at the ordered amount from the day of the move, whether the paying parent or the receiving parent is the one moving.
- A move is not a reason to stop paying. Missed payments become arrears, and interest on them follows the law of the state that issued the order. The arrears and interest calculator estimates a balance.
- Enforcement reaches across state lines. Agencies in the new state can enforce the order, and the federal Office of Child Support Enforcement (OCSE) notes that a child support agency must provide services even when the child or a parent lives outside its jurisdiction (how child support works).
Which state can change the order after you move
Whether the new state can modify the order depends on who still lives where. This guide quotes the Texas version of UIFSA, Texas Family Code, Chapter 159, as an example; every state has enacted the same structure.
The state that issued the order keeps “continuing, exclusive jurisdiction” to modify it as long as the paying parent, the receiving parent or the child lives there when a change is requested (Tex. Fam. Code § 159.205). Here is how that plays out in the common situations:
- The paying parent moves; the receiving parent and child stay. The issuing state keeps control. A request to change the order goes to that state, and its guidelines decide the new amount.
- The receiving parent moves with the child; the paying parent stays. The issuing state still keeps control, because one parent still lives there.
- Everyone has left the issuing state. Now another state can modify the order. The parent asking for the change generally registers the order in a state that has jurisdiction over the other parent, usually where the other parent lives (§ 159.611(a)(1)). This keeps a parent from moving and asking a home court for a better deal.
- Both parents now live in the same new state, and the child no longer lives in the issuing state. That state can register the order and modify it under its own law (§ 159.613).
- Everyone agrees. Even while someone still lives in the issuing state, all the parties can file consent in a record there for a court in the child’s state, or in a state with jurisdiction over one of them, to take over (§ 159.611(a)(2)).
Registering an order in a new state so that it can be enforced there does not, on its own, move the power to change it. The UIFSA guide explains registration and its deadlines.
Asking for a change from another state
Living far from the issuing state does not mean traveling back for every step. UIFSA says a nonresident party’s physical presence in court is not required to modify an order, and a court must let a party or witness who lives out of state testify by telephone, video or other electronic means (Tex. Fam. Code § 159.316). A parent can also go through the child support agency: under § 159.307, an agency must, on request, provide services to a parent in an interstate proceeding, and a parent’s own state can send the case to the agency in the issuing state.
Two timing points matter:
- Ask promptly. Federal law generally bars changing support that has already come due, except back to the date the other parent was notified of a request to modify. A change requested months after a move usually reaches back only to the request, not to the move. The guide to retroactive child support explains the rule.
- Know what counts as a change. The state with jurisdiction applies its own test for when an order can be modified. A move often comes with something that may qualify, such as a new job, a different income, new child care costs or a different parenting schedule. Some states also let a court account for the cost of long-distance travel for parenting time, as an add-on to the guideline amount or a reason to deviate; see when courts deviate from the guidelines.
The guide on how to modify child support covers the process and the thresholds states use.
Comparing the guideline amounts in two states
People often want to know whether the new state’s guidelines would give a different figure. They can, sometimes by a lot, because states use different formulas. But the comparison only matters once the new state has the right to modify the order. Until then, any change is calculated under the issuing state’s guidelines, wherever the parents now live.
Take a family with one child where Parent A earns $60,000 a year and Parent B earns $40,000, and the child lives mainly with Parent B. Under the Mississippi guidelines the guideline amount is about $568 a month. If the same family’s case were heard in Tennessee, the guideline amount would be about $641 a month. Both are estimates; courts can deviate from the guidelines.
Suppose the order was issued in Mississippi:
- If Parent A moves to Tennessee while Parent B and the child stay in Mississippi, Mississippi keeps control. A modification would use the Mississippi figure, not the Tennessee one.
- If both parents and the child later live in Tennessee, a Tennessee court can register and modify the order, and the Tennessee guidelines then set the new amount.
Even then, one thing does not move with the case. A state that modifies another state’s order may not change anything the issuing state’s law makes unchangeable, and the law of the state that issued the original controlling order governs how long support lasts (Tex. Fam. Code § 159.611(c) and (d); federal act § 1738B(h)(2)). Mississippi support generally runs to age 21, while in Tennessee it normally ends at 18. A Tennessee modification of a Mississippi order would set a new monthly amount, but support would still follow Mississippi’s rule on duration. The guide to when child support ends compares the rules by state.
To compare an existing order with the guideline amount in the state that would decide a change, use the modification calculator, or run both states through the child support calculator.
Payments and withholding after a move
For most families, the payment side keeps working with little effort. Income withholding crosses state lines: a withholding order issued in one state can be sent directly to an employer in another, without first registering the order there (Tex. Fam. Code § 159.501). OCSE says employers in one state must recognize withholding orders from other states and keep withholding, regardless of where the parents and children live.
A move often means a new job, though, and that is where gaps appear. The new employer reports the hire to the state, and the agency then sends that employer a withholding notice. Until the first deduction, payments still come due, so the paying parent should pay the state disbursement unit directly. The guide to how child support is paid explains withholding, payment timing and the other ways to pay.
A receiving parent who moves should update the payment address or bank details with the state. A payment that cannot be delivered is delayed even when the paying parent paid on time.
Who to tell, and what to keep
A short checklist for any move:
- Tell the child support agency your new address, phone number and employer. Federal law requires states to have each parent in a support case file this information with the state case registry and keep it up to date (42 U.S.C. § 666(c)(2)(A)), and notices, withholding and enforcement depend on what is on file. OCSE asks parents to tell their caseworker as soon as possible about a move or a new job.
- Tell the court if your order requires it. Some orders set their own notice rules for changes of address or employment; read yours.
- Keep copies of every order, the payment history from the state disbursement unit and pay stubs showing deductions.
- Watch the mail for notices from either state, especially a notice that an order has been registered, which comes with a short deadline to respond.
- Check the custody side separately. Moving with a child can need permission or notice under a custody or parenting-time order. That is a different question from child support, decided under its own rules.
Each state page on this site links that state’s child support agency and official calculator; the list of states shows them all. The child support calculator gives the guideline amount for any state as an estimate. The agency in either state can explain the next step in your case, and a family law attorney can advise on your situation.
