Child Support

How support is calculated, modified, and enforced.

7 min lesson42 U.S.C. § 654; UIFSA

The short version

Child support is money paid by one parent to the other for the financial care of their children after separation or divorce. It helps cover daily needs like food, housing, and clothing. Understanding child support rules ensures your children are financially supported and that you meet your legal obligations.

The law this is built on

Every point below comes from the authority named next to it. Verify the current text before relying on it.

  • 42 U.S.C. § 654

    This federal law requires states to have specific plans for child support enforcement. It outlines the services states must offer, such as locating parents, establishing paternity, setting child support orders, and collecting payments.

    Why it matters: This law ensures that every state has a system in place to help families get and enforce child support orders.

  • UIFSA (Uniform Interstate Family Support Act)

    UIFSA is a uniform state law that helps enforce child support orders across state lines. It dictates which state's court has the power to issue, modify, and enforce child support orders when parents live in different states.

    Why it matters: If you or the other parent move to a different state, UIFSA helps make sure that child support payments continue and orders can be changed or enforced, no matter where you live.

Words you need to know

Child Support Order
This is a legal document from a court that says how much money one parent must pay to the other for the children's care and for how long.
Obligor/Payor
This is the parent ordered to pay child support.
Obligee/Payee
This is the parent who receives child support payments.
Modification
This is the legal process of changing an existing child support order, usually due to a significant change in circumstances like a job loss or a change in a parent's income.
Enforcement
This refers to the legal actions taken to make sure child support payments are made as ordered, such as wage garnishment or license suspension, as provided by state law and federal guidelines (42 U.S.C. § 654).
Imputed Income
This is income a court believes a parent *could* be earning, even if they are not, often used when a parent is voluntarily unemployed or underemployed to avoid paying support.

Your rights

  • ✓You have the right to receive child support payments if you are the primary caregiver for your children.
  • ✓You have the right to request modification of a child support order if there has been a significant change in circumstances.
  • ✓You have the right to have child support orders enforced, including through state agencies and courts (42 U.S.C. § 654).
  • ✓You have the right to a fair calculation of child support based on your state's guidelines.
  • ✓You have the right to seek child support even if you and the other parent live in different states, thanks to UIFSA.
  • ✓You have the right to access child support services offered by your state, including paternity establishment and collection services (42 U.S.C. § 654).

How the process actually works

  1. 1
    Establishing Paternity (if needed)
    Before a child support order can be made.

    Before child support can be ordered, the legal father of the child must be identified. This can be done voluntarily or through a court order. States are required to offer paternity establishment services (42 U.S.C. § 654).

  2. 2
    Calculating Support
    When a child support order is first created.

    Child support is typically calculated using state-specific guidelines, often based on parents' incomes, the number of children, and the amount of time each parent spends with the children. Each state has its own formula.

  3. 3
    Issuing the Order
    After calculation and review by a court.

    A judge signs a formal order detailing how much support is to be paid, by whom, to whom, and how often. This order is legally binding.

  4. 4
    Collecting Payments
    Ongoing, after the order is issued.

    Payments can be made directly between parents or, more commonly, through a state child support agency which helps collect and distribute payments (42 U.S.C. § 654). This often involves wage withholding.

  5. 5
    Modifying the Order
    When there's a significant change in a parent's life or the child's needs.

    If a parent's income changes significantly, or if the children's needs change, a parent can ask the court to change the existing order. A substantial change in circumstances is usually required.

  6. 6
    Enforcing the Order
    When payments are missed or not made in full.

    If payments are not made, the state child support agency or the obligee can take legal steps to enforce the order. These can include wage garnishment, bank account liens, or suspension of driver's licenses (42 U.S.C. § 654).

Deadlines that can end your case

  • Age of Majority
    Varies by state (typically 18 or 21)

    Child support generally ends when a child reaches the age of majority or graduates high school, whichever occurs later, but some states extend it for college or disability. If you miss this date, you might overpay or miss payments you are owed.

  • Request for Modification
    Varies by state (usually when a 'material change in circumstances' occurs)

    There isn't a strict deadline, but if you wait too long to request a modification after a major income change, you could owe more in back support or receive less than you need for a long time.

Costly mistakes

  • ✕Not getting a formal child support order: Relying on verbal agreements can lead to disputes and make enforcement difficult.
  • ✕Not notifying the court of income changes: This can lead to overpaying or underpaying, resulting in large arrears or missed support.
  • ✕Stopping payments because of visitation issues: Child support and visitation are separate legal matters. Withholding support due to visitation problems is illegal.
  • ✕Ignoring interstate rules: If parents live in different states, failing to follow UIFSA can complicate enforcement and modification.
  • ✕Failing to keep accurate records: Not tracking payments made or received can make it hard to prove compliance or arrears in court.
  • ✕Trying to modify or enforce an order without legal process: You must go through the court or child support agency; you cannot change or enforce an order on your own.

Your checklist

  1. If not already done, establish paternity for the child.
  2. Gather financial documents: income statements, tax returns, proof of expenses for children.
  3. Contact your state's child support agency for assistance in calculating and establishing an order (42 U.S.C. § 654).
  4. Attend all scheduled court hearings or appointments.
  5. Once an order is in place, keep detailed records of all payments made or received.
  6. If your income or the other parent's income changes significantly, or if custody arrangements change, seek legal advice about modifying the order.
  7. If payments are not being made, contact your state's child support agency for enforcement assistance (42 U.S.C. § 654).

Common questions

How is child support calculated?

Each state has its own specific guidelines for calculating child support. These guidelines typically consider both parents' incomes, the number of children, and the amount of time each parent spends with the children. Some states also factor in healthcare costs and childcare expenses.

What if the other parent lives in a different state?

If the other parent lives in a different state, the Uniform Interstate Family Support Act (UIFSA) applies. This law helps states cooperate to establish, modify, and enforce child support orders across state lines. You would typically work with your state's child support agency, which can then work with the agency in the other state.

Can I stop paying child support if I don't see my children?

No, child support payments and visitation are separate legal matters. You cannot legally stop paying child support even if the other parent is denying you visitation. You must seek a court order to address visitation issues separately.

When does child support usually end?

Child support generally ends when the child reaches the 'age of majority' in your state, which is typically 18 or 21. However, it might continue longer if the child is still in high school, has special needs, or is attending college, depending on your state's laws or the specific court order.

What happens if a parent doesn't pay child support?

If a parent doesn't pay child support, the state child support enforcement agency can take various actions, as required by 42 U.S.C. § 654. These can include wage garnishment, intercepting tax refunds, suspending driver's or professional licenses, placing liens on property, or even referring the case for criminal prosecution in extreme circumstances.

How this changes by state

Child support laws vary significantly from state to state. While federal law (42 U.S.C. § 654) requires all states to have child support enforcement programs, the specific formulas for calculating support, the age at which support ends, and the exact methods of enforcement are determined by each state's individual laws. To find your state's specific rules, you should contact your state's Department of Health and Human Services or Child Support Enforcement Agency, or visit their official government website.

When you need a lawyer

You should consider getting a lawyer if the other parent is difficult to locate, if paternity is disputed, if you or the other parent have complex finances or own a business, or if the case involves interstate issues where parents live in different states. A lawyer is also crucial if you face enforcement actions for unpaid support, or if you believe the support order needs modification due to a major life change.
