Child Support Laws in Maryland “My child’s future should not suffer because we couldn’t make it work.”
This is the voice of countless parents navigating divorce or separation in Maryland. Whether you’re paying or receiving child support, the emotions involved—fear, frustration, guilt, and hope—are deeply real.

But the system is here to help. And if you know how it works, you can make informed decisions that protect your child’s future and your financial health.

In this guide, we’ll answer every major question Maryland parents have about child support in 2025 — including how it’s calculated, how to use the official calculator, how to reduce or modify child support, and what to do if you want to claim retroactive payments or stop payments legally.

🔍 Quick Overview: Maryland Child Support in 2025

Maryland follows an Income Shares Model for child support. This means the total support obligation is split between both parents in proportion to their incomes. The model assumes that a child should receive the same financial support they would have if their parents had stayed together.

As of 2025, Maryland uses the Revised Child Support Guidelines that consider:

• Combined adjusted actual income of both parents
• Number of children
• Custody type (sole/shared/third-party)
• Health insurance and extraordinary medical expenses
• Child care costs for employment

📊 Use the Official Maryland Child Support Calculator (2025)

Before jumping to court or negotiation, calculate your estimated support using the official Maryland Child Support Calculator provided by the state.

👉 Use Maryland’s Online Child Support Calculator (2025)

This tool gives you a fairly accurate estimate based on:

• Monthly income of both parents
• Existing support obligations
• Custody arrangement
• Health insurance premiums
• Child care costs

🔹 Pro tip: Have all your income and expense documents ready before using the tool.

⚖️ How Child Support is Calculated in Maryland (2025)

Here’s how the math works:

1. Add Both Parents’ Gross Monthly Incomes
2. Apply the Maryland Guidelines Schedule to find the Basic Child Support Obligation.
3. Add child care, extraordinary medical, and health insurance costs.
4. Determine each parent’s percentage of total income.
5. Assign the support obligation proportionally to each parent.

For example: If the basic obligation is $1,200/month and you earn 60% of the combined income, your responsibility is $720/month.

🔄 How to Modify Child Support in Maryland (2025)

Can you lower your child support payments? Yes — if your circumstances have changed.

✏️ Valid reasons to request modification:

• Significant change in income (job loss, promotion, disability)
• Change in custody arrangement
• Child’s needs have changed (e.g., medical condition)
• Parent has additional children to support

🔧 How to request a modification:

1. Fill out a Petition to Modify Child Support
2. File it with the Maryland Circuit Court
3. Attend the hearing with evidence of the change

💡 Reminder: You must show that the change is substantial and continuing — not temporary.

⏪ Retroactive Child Support in Maryland: Can You Claim It?

Yes — but it depends on the situation.

📅 When retroactive child support may apply:

• You delayed filing but were owed support
• The paying parent misrepresented their income
• There was a deliberate delay or fraud

⚠️ What Maryland Law Says:

Maryland generally allows retroactive support only from the date of filing the motion — not before. However, if there’s a delay due to deceit, courts may grant support going back further.

🚫 How to Stop or Terminate Child Support in Maryland

Child support doesn’t last forever. Here’s when it ends and how you can legally stop it:

✅ When support automatically ends:

• When the child turns 18 (or 19 if still in high school full-time)
• If the child becomes emancipated
• If the child passes away

✍️ Steps to stop payment legally:

1. File a Petition to Terminate Child Support
2. Attach proof of the qualifying event (graduation, death certificate, etc.)
3. Wait for court approval before stopping payments

❌ Don’t stop payments without legal termination — it can lead to arrears and legal action.

💡 Real Questions, Real Answers

➤ Do both parents always have to pay?

Yes. Even in sole custody, the non-custodial parent usually pays. In shared custody, both share expenses based on income.

➤ What if the other parent won’t pay?

File a contempt motion. Maryland can enforce payment through:

• Wage garnishment
• Tax refund intercept
• License suspension
• Jail time (in extreme cases)

➤ Can I avoid going to court?

Yes. You can use mediation or work with the Child Support Enforcement Administration (CSEA).
