Yes. If you do not have custody of your child, you almost always have to pay child support. Family courts treat both parents as financially responsible for their children, and the parent who does not have primary custody makes payments to the parent who does. The duty comes from being a parent, not from where the child sleeps most nights, and it stays in force until a court changes the order or the child ages out of eligibility.
Federal law also keeps the obligation attached to you across state lines. The Full Faith and Credit for Child Support Orders Act requires every state to enforce a valid support order from any other state, and bars states from modifying another state’s order except in narrow circumstances.1GovInfo. 28 USC 1738B – Full Faith and Credit for Child Support Orders Moving does not reset the clock.
Can You Stop Paying If You’re Denied Visitation?
No. This is the single most common misunderstanding in family law. Courts treat custody, visitation, and child support as legally independent obligations. If the custodial parent blocks your parenting time, your remedy is to go back to court and enforce the custody order. Withholding payments in retaliation puts you in contempt and does nothing to fix the visitation problem.
The reverse is also true. A custodial parent cannot refuse visitation because the other parent is behind on payments. Each obligation stands on its own. Violating one because the other parent violated theirs just means both parents are now in contempt.
How the Payment Amount Is Set
Most states use one of two formulas. Forty-one states follow the income shares model, which estimates what parents would have spent on the child if they still lived together and splits that amount based on each parent’s share of their combined income. Six states use the percentage of income model, which bases the payment solely on the non-custodial parent’s earnings.2National Conference of State Legislatures. Child Support Guideline Models The remaining jurisdictions use variations or hybrid approaches.
Income for these calculations goes beyond your paycheck. Courts look at wages, salaries, bonuses, commissions, rental income, dividends, and sometimes benefits like workers’ compensation or disability payments. Allowable deductions vary but commonly include taxes, health insurance premiums for the child, and pre-existing support obligations for other children.
Quitting a job or taking a lower-paying position to shrink the number rarely works. When a court finds a parent is voluntarily unemployed or underemployed, it can impute income based on what the parent could be earning given their education, work history, skills, and the local job market. Judges have broad discretion to reject claims that a parent cannot find better work, especially when the income drop lines up suspiciously with a support proceeding.
What Can Raise or Lower the Number
The formula produces a baseline. Several factors adjust it.
- Parenting time. More overnight stays with the non-custodial parent often reduces the payment, since that parent is covering food, utilities, and other costs directly during those periods. Shared custody arrangements where each parent has the child roughly half the time can significantly lower or even eliminate the transfer payment.
- Health insurance. Courts routinely order one or both parents to maintain coverage for the child. A qualified medical child support order can require a parent’s employer-sponsored group health plan to cover the child as a beneficiary, and the cost of that coverage gets factored into the support calculation.3Legal Information Institute. Qualified Medical Child Support Order (QMCSO)
- Special needs. A child with a disability or chronic medical condition may need therapy, specialized equipment, or extra supervision, all of which increase the support amount.
- Age of the child. Older children tend to cost more. Teenagers have expenses for school activities, transportation, and college preparation that younger children do not.
- Extraordinary expenses. Tutoring, private school tuition, or travel costs for visitation can factor into the final order if one parent raises them and the court finds them reasonable.
What Happens If You Don’t Pay
Enforcement in this area is aggressive, because the money is meant for a child. The consequences escalate quickly.
Wage Garnishment
The most common tool is wage garnishment, where your employer redirects part of your paycheck to the custodial parent or a state agency. Federal law allows up to 50% of your disposable earnings if you are supporting another spouse or child, or up to 60% if you are not. If you are more than 12 weeks behind, an additional 5% can be added on top of those limits.4Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Those percentages run well above the 25% cap that applies to ordinary consumer debts.5U.S. Department of Labor. Fact Sheet 30 – Wage Garnishment Protections of the Consumer Credit Protection Act
Passport Denial
Owe more than $2,500 in past-due support and the federal government will deny your passport application or revoke an existing passport. State child support agencies certify delinquent cases to the Department of Health and Human Services, which passes the information to the State Department.6Office of the Law Revision Counsel. 42 USC 652 – Duties of Secretary You will not get a passport until the arrears are resolved.
License Suspensions and Property Seizures
States can suspend your driver’s license, professional licenses, and recreational licenses when you fall behind. Federal and state tax refunds can be intercepted and applied to your debt. Some states also place liens on property or bank accounts.
Credit Damage
Child support arrears typically appear on your credit report after 60 to 90 days of non-payment. State enforcement agencies report delinquent accounts to the major credit bureaus, and the arrears show up like a collection account. That can affect your ability to qualify for loans, rent housing, or pass employer background checks.
Federal Criminal Charges
Willfully failing to pay support for a child living in another state is a federal crime. A first offense carries up to six months in prison. If the amount owed exceeds $5,000 or the payments are more than a year overdue, or if the parent flees across state lines to avoid paying, the offense becomes a felony punishable by up to two years in prison. Courts must also order restitution equal to the full unpaid balance.7Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations
When the Obligation Ends
Child support is not permanent, but the end date depends on your state. In most states, the obligation runs until the child turns 18. Many extend it to 19 if the child is still in high school, and a handful continue support to age 21.8National Conference of State Legislatures. Termination of Child Support Other events that commonly end the obligation include the child’s marriage, entry into the military, or legal emancipation.
Reaching the termination age does not erase unpaid balances. If you owe arrears when the child ages out, you still owe that money, and enforcement actions can continue until it is paid in full.
Two situations extend the duty beyond the usual cutoff. Most states allow courts to extend support indefinitely when an adult child has a severe mental or physical disability that began before the age of majority and prevents independent living. And a number of states empower courts to order one or both parents to contribute to post-secondary education costs, sometimes into the child’s early twenties.9Justia. College Expenses and Child Support Laws Even in states without a statute on point, parents can agree to share college costs in their divorce or custody agreement, and that agreement is enforceable as part of the court order.
If Your Circumstances Change
A child support order is not fixed forever. Either parent can petition the court to modify the amount when circumstances change significantly. Common grounds include job loss, a major income change for either parent, a change in custody arrangements, or a substantial shift in the child’s needs such as a new medical condition. Many states also allow a review every three years as a matter of course. The key word is “significant.” Courts are not interested in minor or temporary fluctuations.
Here is where many parents get tripped up: filing for a modification does not pause your existing obligation. Under federal law, every support payment becomes a judgment the moment it comes due, and courts cannot retroactively reduce or forgive payments that have already accrued.10Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement A modification can only apply going forward, and at the earliest from the date you file the petition and give notice to the other parent. Lose your job in January and wait until June to file, and you owe the full original amount for those five months. There is no backdating, no matter how sympathetic the circumstances. File immediately when your situation changes.
