The parent still owes child support, even if grandparents have custody

When a grandparent has custody of a child, the biological parent is still legally responsible for child support. The court does not erase that obligation because someone else is raising the child. The grandparent can file for child support in family court, and the judge will order the parent to pay based on their income and the state's child support formula.

The amount owed does not change because a grandparent is the custodian instead of the other parent. The court calculates support the same way: it looks at both parents' incomes, custody time, and state guidelines. What changes is who receives the payment — the grandparent gets it instead of the other parent.

Key Takeaways

  • A biological parent remains obligated to pay child support even when a grandparent has full custody.
  • The grandparent must file a child support case in family court; the obligation does not happen automatically.
  • The court calculates the amount using the same income-based formula it uses for all child support cases in that state.
  • If the parent refuses to pay, the grandparent can ask the court to enforce the order through wage garnishment or other collection methods.

How a grandparent files for child support

The grandparent files a petition in family court in the county where the child lives. They will need to show that they have custody — either through a custody order from the court or through guardianship papers. The court will then notify the parent that a child support case has been opened.

The parent receives a summons and a copy of the petition. They have a deadline to respond, usually 20 to 30 days depending on the state. If the parent does not respond, the court can enter a default order, meaning the judge decides the amount without hearing from the parent.

Both parents must disclose their income and financial information. The grandparent will also need to provide proof of custody and information about the child's needs — school costs, medical expenses, childcare, and other regular expenses. The court uses this information along with the state's child support guidelines to calculate what the parent should pay.

What happens if the parent does not pay

If the parent stops paying or never starts, the grandparent can ask the court to enforce the order. The most common enforcement method is wage garnishment, which means the court orders the parent's employer to send part of each paycheck directly to the grandparent.

The court can also place a lien on the parent's property, intercept tax refunds, suspend their driver's license, or hold them in contempt of court. The specific tools available depend on the state and how far behind the parent is on payments.

If the parent's income changes — they lose a job, get a raise, or have a significant life change — either the grandparent or the parent can ask the court to modify the order. The court will recalculate based on current income.

When a parent claims they cannot afford to pay

If a parent says they have no income or very low income, they still owe child support. The court does not eliminate the obligation; instead, it may set the amount very low or order the parent to pay what they can. Some states have a minimum amount — often $50 per month — that a parent must pay even if they are unemployed.

The parent can ask the court to reduce the amount if their circumstances change. They must file a motion to modify and show proof of their current income — pay stubs, unemployment benefits, or a statement from their employer. The court will not reduce the order without evidence.

If a parent is incarcerated, the obligation usually continues to accrue, meaning they owe back support that builds up while they are in prison. Some states allow the parent to ask for a temporary reduction while incarcerated, but the debt does not disappear.

The difference between child support and guardianship

Guardianship and custody are not the same as child support. A grandparent can have legal guardianship of a child — meaning they make decisions about school, medical care, and where the child lives — but that does not automatically create a child support obligation on the parent. The grandparent must file a separate child support case to collect money from the parent.

Some grandparents receive guardianship but never pursue child support because they do not know they can, or because they cannot locate the parent. Others pursue it immediately. The choice is the grandparent's, but the parent's legal obligation to support the child does not depend on whether the grandparent files.

What if both parents are unable or unwilling to pay

If the parent cannot be found, has no income, or refuses to pay and the court cannot enforce the order, the grandparent may have other options. Some states offer kinship care subsidies or guardianship subsidies — monthly payments from the state to help grandparents cover the cost of raising a grandchild. These are separate from child support and are based on need and the grandparent's income.

The grandparent can also look into other programs: Temporary Assistance for Needy Families (TANF), Supplemental Security Income (SSI) if the child has a disability, or the Supplemental Nutrition Assistance Program (SNAP). These programs do not replace child support, but they can help cover basic costs while the grandparent pursues a support order.

How state law affects the amount and process

Every state has its own child support formula and its own rules about how much a parent must pay. Some states use the income shares model, which divides the cost of raising the child between both parents based on their income percentages. Others use the percentage of income model, which sets support as a percentage of the paying parent's income.

The state also sets the maximum income level used in calculations. If a parent earns above that level, the court may use discretion to set a higher amount, or it may cap the calculation at the state maximum. States also differ on whether they count overtime, bonuses, or self-employment income, and whether they adjust the amount based on how much time the child spends with each parent.

Because these rules vary, the amount owed in one state may be very different from the amount in another state. A grandparent should speak with the family court clerk or a family law attorney in their state to understand how their state calculates support and what the process looks like.

Frequently Asked Questions

Can a grandparent get child support if the parent is on disability or unemployment?

Yes. Disability benefits and unemployment payments are counted as income for child support purposes. The court will calculate support based on these payments. If the parent has no income at all, the court may set a minimal amount or order the parent to pay what they can, but the obligation does not disappear.

What if the parent wants to give up parental rights to avoid paying child support?

A parent cannot simply surrender parental rights to escape child support. Courts do not allow this. The only way a parent's obligation ends is if someone else legally adopts the child — for example, if the grandparent adopts the child, the biological parent's support obligation may end, but adoption is a separate legal process from custody or guardianship.

Does the grandparent have to pay child support to the other parent?

No. The grandparent has no legal obligation to pay support to either biological parent. The grandparent's role is to care for the child. The biological parents remain responsible for supporting their own child, regardless of who has custody.

How long does child support last when a grandparent has custody?

Child support continues until the child reaches the age of majority in that state, usually 18. In some states it extends to 19 or 21 if the child is still in high school or has a disability. The grandparent can ask the court to extend support beyond the normal age if the child has special needs.

Can the grandparent and parent agree to a child support amount without going to court?

They can agree on an amount, but the agreement must be approved by the court to be enforceable. If the parent stops paying, the grandparent will need a court order to collect through wage garnishment or other enforcement methods. An informal agreement has no legal force if the parent changes their mind.
