Life rarely stands still after a divorce or separation. Jobs change, children grow, and parenting schedules shift. If the child support amount you agreed to or were ordered to pay no longer fits your family’s reality, you may be wondering how to modify child support in Maryland. The good news is that child support is never set in stone. The key is knowing what the court requires, which path to take, and why acting quickly matters.
This guide walks through the legal standard, the difference between changing a child support agreement and a court order, the step-by-step process, and the common mistakes that cost parents money.
Key takeaways
- A Maryland court can change child support only after someone files a request and shows a “material change of circumstance.”
- Child support terms in a separation or settlement agreement can be modified by a court if the change is in the child’s best interests, even if the agreement says otherwise.
- A new amount can only reach back to the date the motion was filed, never earlier, so waiting can be expensive.
- A private or verbal agreement between parents does not change a court order. Only a new court order does.
- You can file a motion with the circuit court or ask the Child Support Administration to review your case.
Can Child Support Be Changed in Maryland?
Yes. Under Maryland Code, Family Law § 12-104, a court “may modify a child support award subsequent to the filing of a motion for modification and upon a showing of a material change of circumstance.”
That sentence contains two requirements:
- Someone has to file. The court will not revisit support on its own, and neither parent can change the amount unilaterally.
- The change has to be material. A “material” change is one that is significant and relevant to the support calculation. According to the Maryland People’s Law Library, a change in income of about 25% generally qualifies, although smaller changes can be raised depending on the facts.
When a modification is granted, the court recalculates support using the current Maryland Child Support Guidelines, which consider both parents’ incomes, the number of overnights each parent has, work-related child care costs, health insurance, and extraordinary medical expenses.
Modifying a Child Support Agreement vs. a Court Order
Many families at Jacobson Family Law set child support through a negotiated agreement rather than a contested trial. So what happens when that agreement needs to change?
If your support terms are in a court order, you ask the court that issued the order to modify it.
If your support terms are in a separation or marital settlement agreement, Maryland law still gives the court the final say. Family Law § 8-103(a) allows a court to modify any provision of an agreement “with respect to the care, custody, education, or support of any minor child” when the modification is in the child’s best interests. In other words, parents cannot contract their way out of the court’s authority over child support. This is also why parents cannot simply agree to waive child support altogether.
When parents divorce, their marital settlement agreement (MSA) is often incorporated into the final divorce judgment, making its child support terms enforceable as part of a court order. If you are drafting an agreement now, it is worth planning ahead. Thoughtful separation agreements can build in periodic income exchanges, cost-sharing rules for activities or tuition, and a process for revisiting support, which makes future changes far less stressful.
Common Reasons to Request a Child Support Modification
Every family is different, but these situations frequently support a request to modify child support in Maryland. For a deeper look at each one, read our guide to the top reasons to modify child support in Maryland.
- A significant change in either parent’s income, such as involuntary job loss, a reduction in hours, a disability, or a substantial raise.
- A change in the parenting schedule. Maryland uses the shared physical custody formula when each parent has the children for more than 25% of overnights (92 nights a year). Crossing that line in either direction can change the calculation. Learn more about how shared physical custody affects child support, and if the schedule itself needs to change, see when you can modify a child custody order in Maryland.
- Changes in the child’s needs, including new medical, therapy, or special education costs.
- Changes in child care or health insurance costs, which are built into the guidelines calculation.
- A child aging out of support. Support generally ends at 18, but continues until 19 if the child is still enrolled in high school. When one of several children ages out, support for the remaining children usually needs to be recalculated.
- Incarceration. Section 12-104 specifically allows a court to find a material change when a parent’s ability to pay is sufficiently reduced by incarceration.
- Other children in a parent’s household. Maryland’s multifamily adjustment, effective October 1, 2025, lets the court account for other children a parent supports at home. According to the Maryland Department of Human Services, the new law alone does not trigger a modification, but the court may apply it once a motion to modify is filed for another reason.
What Usually Does Not Justify a Change
- Voluntarily reducing your income. If a parent quits a job or takes lower pay to reduce support, a court can find “voluntary impoverishment” and calculate support based on what that parent could earn.
- Small or temporary fluctuations. A slow month or a one-time bonus is rarely enough on its own.
- An informal side deal. Even if both parents agree to a new amount, the existing order remains enforceable until a judge signs a new one. Unpaid amounts under the old order can accumulate as arrears.
How to Modify Child Support in Maryland: Step by Step
Step 1: Gather Your Financial Information
Collect recent pay stubs, tax returns, proof of any job loss or new employment, child care invoices, health insurance premium statements, and a record of the current parenting schedule. Running an estimate with the state’s child support guidelines calculator can help you see whether the change is likely to move the numbers in a meaningful way.
Step 2: Try to Reach an Agreement First
If you and your co-parent can communicate, a negotiated modification is almost always faster, less expensive, and less stressful for everyone, especially your children. Divorce mediation gives both parents a neutral space to review updated finances and agree on a new amount. It is one of the reasons more Maryland families are choosing mediation over litigation.
Once you agree, the terms should be put in writing and submitted to the court as a consent order so the change is legally binding.
Step 3: File a Motion to Modify Child Support
If you cannot agree, or if you need to protect your filing date right away, file a Motion to Modify Child Support (Form CC-DR-006) along with a Financial Statement (Child Support Guidelines) (Form CC-DR-030) in the circuit court that issued your current order. Both forms are available in the Maryland Courts family law forms index, and self-represented parents can get procedural help from a Family Law Self-Help Center. The other parent must be served and has the opportunity to respond, and the court may schedule a settlement conference or hearing.
If your original order came from another state, different jurisdiction rules apply. See our guide on how to modify an order from out of state.
Step 4: Or Request a Review Through the Child Support Administration
If your case is handled through the Maryland Child Support Administration (CSA), either parent can request a review in writing. Under COMAR 07.07.05.03, orders may be reviewed every 36 months, or sooner when there has been a material change in circumstances. You will need to complete the CSA modification packet, including a questionnaire and financial statement, and submit it to your local child support office.
The CSA route can be a helpful way to modify child support in Maryland if your case is already in its system. Keep in mind, though, that the review can take up to 180 days, and the agency does not represent either parent. The amount it pursues may be different from what you hoped for.
Step 5: Keep Following the Current Order
Until a judge signs a new order, the existing one stays in effect. Keep paying (or keep records of what you receive) exactly as ordered. If the other parent is not complying, learn what you can do when your ex doesn’t follow a court order in Maryland.
Court Motion vs. CSA Review: Which Is Right for You?
| Court Motion | CSA Review | |
|---|---|---|
| Who can use it | Either parent, at any time, with a material change | Either parent in a CSA case |
| How often | Whenever a material change occurs | Every 36 months, or sooner with a material change |
| Timing | A new amount can reach back to the day you file | Review can take up to 180 days before the agency decides whether to file |
| Control | You present your own case (with or without an attorney) | The agency decides what to pursue and does not represent you |
| Best for | Time-sensitive changes, disputed facts, agreed consent orders | Straightforward income changes in existing CSA cases |
Don’t Wait: Modifications Are Not Retroactive
This is the most expensive mistake we see. Section 12-104(b) says a court “may not retroactively modify a child support award prior to the date of the filing of the motion for modification.”
That means if you lose your job in March but do not file until September, the court cannot reduce the support that came due between March and September. The same rule works in reverse for a parent who should be receiving more. If your circumstances have changed and you need to modify child support in Maryland, file promptly, even while you continue trying to reach an agreement.
Frequently Asked Questions About Modifying Child Support in Maryland
Can we change child support without going to court?
Parents can negotiate a new amount on their own or through mediation, but the change is not legally enforceable until a court approves it. Submitting a signed consent order lets you modify child support in Maryland without a contested hearing.
Can child support in our marital settlement agreement be modified?
Yes. Under Family Law § 8-103, a court can modify child support provisions in an agreement when the change is in the child’s best interests, regardless of what the agreement says.
How far back can a child support modification go?
No earlier than the date the motion to modify was filed. The court cannot change support that came due before that date.
What counts as a material change in circumstances?
It is a significant change relevant to the support calculation, such as a substantial change in income, a new parenting schedule, or new child care or medical costs. A change in income of about 25% generally qualifies, but each case depends on its facts.
Do I have to keep paying while my modification is pending?
Yes. The current order remains in effect until a judge signs a new one. Stopping or reducing payments on your own can result in arrears and enforcement action.
How often can child support be reviewed?
You can file a motion with the court whenever a material change occurs. Through the Child Support Administration, reviews are available every 36 months, or sooner if circumstances have materially changed.
