No. Child support does not automatically stop at 18 in Maryland. The obligation to pay current support generally ends when your child turns 18, but the court order directing your payments stays active until a judge officially closes it.1Maryland Department of Human Services. Paying Child Support FAQs If you stop paying on your own, every missed payment stacks up as arrears with full enforcement consequences. Several exceptions can also push the obligation past that birthday.
The Age 18 Rule
Maryland ties the end of child support to the age of majority, which is 18.1Maryland Department of Human Services. Paying Child Support FAQs At that point, the state considers your child a legal adult, and the underlying legal duty to pay current support generally ends.
What the age cutoff does not do is close the case, adjust the amount, or notify your employer. Those are separate steps that require action from you or from the Child Support Enforcement Administration.
What Happens When One of Several Children Turns 18
This is where paying parents lose the most money. If your order covers more than one child, the total monthly payment does not drop when the oldest ages out. The full amount remains legally enforceable until a judge signs a modified order recalculating support based on the remaining minor children.1Maryland Department of Human Services. Paying Child Support FAQs
Paying what you think the new amount “should” be creates arrears on the difference. File to modify as soon as your oldest child crosses the threshold.
Exceptions That Extend Support Past 18
High School Enrollment
If your child turns 18 while still enrolled full-time in high school, support does not end at the birthday. It continues until the child graduates or turns 19, whichever comes first.1Maryland Department of Human Services. Paying Child Support FAQs Neither parent has to file anything to trigger this; the existing order simply stays in effect.
A Destitute Adult Child
Maryland law uses the term “destitute adult child” to describe an adult child who has no means of self-support due to a mental or physical condition.2Maryland General Assembly. Maryland Code Family Law 13-101 A parent with the financial ability to help is legally prohibited from refusing to provide food, shelter, care, and clothing. Failing this duty is a misdemeanor carrying a fine of up to $1,000, up to a year of imprisonment, or both.3Maryland General Assembly. Maryland Code Family Law 13-102
The court looks at whether the adult child truly cannot become self-sufficient and whether the parent has income or earning capacity to help. When both are true, support can continue indefinitely. The parent seeking continued support typically needs medical evidence documenting the child’s inability to live independently.
How to Formally End the Order
To close out current support, file a motion to modify or terminate child support with the circuit court that issued the original order. Maryland Courts provides a standardized form (CC-DR-006) with step-by-step instructions for self-represented filers.4Maryland Courts. Petition/Motion to Modify Child Support Instructions for Completing Form CC-DR-006 The filing fee is $31 per motion.5Maryland Courts. Summary of Charges, Costs and Fees of the Clerks of the Circuit Court You can also file through your local child support enforcement office or hire an attorney.
If your case runs through the Child Support Enforcement Administration, you can send a written statement to your case specialist explaining the facts, which may simplify things in straightforward situations.1Maryland Department of Human Services. Paying Child Support FAQs
Wage Withholding Keeps Running Until Someone Stops It
If payments come out of your paycheck through a wage withholding order, your employer will keep deducting until told otherwise. The employer has no way of knowing your child turned 18 and no authority to stop on its own.
Two paths end the withholding. If the support obligation has been terminated and all arrears are fully paid, the Child Support Enforcement Administration can notify the employer directly without a separate court order. If arrears remain, you need to file a motion with the court to terminate the withholding, which the court will grant once it confirms the obligation is fulfilled and any balance is cleared. Move quickly. Overpayments are difficult to recover after the fact.
Arrears Do Not Disappear at 18
When current support ends, any past-due balance stays. Unpaid child support remains a legally enforceable debt, and the Child Support Enforcement Administration will keep pursuing collection regardless of your child’s age.1Maryland Department of Human Services. Paying Child Support FAQs
The tools remain aggressive. The state can garnish wages, intercept federal tax refunds once arrears reach $500 or more and equal at least two months of the support obligation, and suspend a driver’s license.1Maryland Department of Human Services. Paying Child Support FAQs Under Maryland’s general rule for court-ordered debts, each individual missed payment carries its own 12-year collection window from the date that payment was due, so old arrears can remain collectible across many years.
If You Kept Paying After 18
Recovering overpayments is possible but not guaranteed. Courts have discretion to grant or deny reimbursement based on the circumstances. A parent who kept paying without realizing the obligation ended generally has a stronger case than one who voluntarily overpaid.
Timing is the whole ballgame. Courts in Maryland typically limit retroactive relief to the date a motion was filed, not the date the overpayment started. Every month you delay filing after your child reaches the relevant age threshold is a month you may never get back. Keep records of every payment and file the motion promptly.
Health Insurance Is a Separate Order
Many child support orders require one parent to keep the child on health insurance. When support ends, the insurance obligation in the support order typically ends with it, though the child may remain eligible under a parent’s employer plan until age 26 under federal law.
If coverage was set up through a Qualified Medical Child Support Order, the child cannot be dropped from the plan unless the court order is no longer in effect, the child is enrolled in comparable coverage, or the employer eliminates family coverage entirely.6U.S. Department of Labor. Qualified Medical Child Support Orders Check whether a separate medical support order is still active before making any changes. Dropping a child from insurance while a medical support order is in place can lead to contempt proceedings.
