Maryland parents seeking to change child support must file Form CC-DR-006 with the circuit court and demonstrate a material change in circumstances under Md. Code, Family Law § 12-104. The filing fee ranges from $165 to $312 depending on whether you file an initial petition or a post-judgment motion. A 25% or greater change in either parent's income typically qualifies as sufficient grounds for modification. Maryland courts will not modify support retroactively before the filing date, so parents should file promptly after experiencing a qualifying change. The modification process takes 90-180 days from filing to final order.

What Qualifies as a Material Change of Circumstances in Maryland
Md. Code, Family Law § 12-104 requires parents to prove a material change of circumstances before courts will modify child support in Maryland. A material change must be involuntary, substantial, and likely to continue for the foreseeable future. Maryland courts apply a three-part test examining relevance to the child's support needs, magnitude of the change, and permanence.
The most common qualifying changes include significant income fluctuations in either parent's earnings. Maryland courts generally accept an income change of 25% or more as automatically meeting the substantiality requirement. If a parent earning $6,000 per month experiences a job loss resulting in unemployment benefits of $3,000 monthly, that 50% reduction clearly qualifies. However, voluntary unemployment or underemployment will not support a modification request.
Income-Based Changes That Qualify
Income changes of 25% or more constitute the clearest path to child support modification in Maryland. Courts examine gross monthly income as defined under Md. Code, Family Law § 12-201, which includes wages, salaries, commissions, bonuses, self-employment income, pensions, Social Security benefits, workers' compensation, unemployment insurance, alimony received, and investment income.
The 25% threshold applies to either parent. If the paying parent's income decreases by 25% or more, they may petition to reduce the support obligation. Conversely, if the paying parent's income increases by 25% or more, the receiving parent may petition to increase support. Similarly, changes in the receiving parent's income can justify modifications in either direction.
Maryland's 2026 Multifamily Adjustment under House Bill 275 introduced new considerations for parents supporting additional children in their household. Under amended Md. Code, Family Law § 12-201(c), parents may deduct 75% of support obligations for qualifying children living in their household when calculating adjusted actual income.
Custody Changes That Trigger Modifications
Custody arrangements crossing the 92-overnight threshold qualify as material changes under Maryland law. The 92-overnight mark represents 25% of the calendar year and triggers different child support calculations under Md. Code, Family Law § 12-204(d). When a noncustodial parent begins keeping the child for 92 or more overnights annually, the court must recalculate support using Worksheet B instead of Worksheet A.
This custody-based modification affects both the basic support obligation and the proportional allocation between parents. Under shared physical custody calculations, each parent receives credit for direct expenses incurred during their parenting time. A parent whose overnight percentage increases from 20% to 35% would see a substantial reduction in their support obligation under the recalculated guidelines.
Other Qualifying Material Changes
Beyond income and custody shifts, Maryland courts recognize several additional circumstances warranting child support modification. A child aging out of daycare represents a common qualifying change, as childcare expenses factor directly into support calculations under Md. Code, Family Law § 12-204(g). When a child reaches school age and no longer requires full-time daycare, the elimination of $1,000-$2,000 monthly childcare costs justifies recalculation.
Significant changes in health insurance costs qualify when a parent gains or loses employer-sponsored coverage. Under the guidelines, health insurance premiums paid for the child are added to the basic support obligation and divided proportionally. A parent whose employer eliminates dependent coverage, forcing purchase of individual market insurance at substantially higher rates, may petition for modification.
Incarceration for 180 consecutive days or more qualifies as a material change under Maryland case law, provided the incarceration was not the result of intentional conduct designed to avoid support obligations. This recognizes that imprisoned parents cannot maintain employment income while serving sentences, though courts scrutinize whether the underlying criminal conduct represents willful support evasion.
How to File for Child Support Modification in Maryland
Filing for child support modification in Maryland requires completing Form CC-DR-006 and submitting it to the circuit court that issued the original support order. The filing fee is $165 for initial petitions or $312 for post-judgment motions, as of May 2026. Parents unable to afford fees may request waivers under Md. Code, Courts Article § 7-201 by demonstrating household income at or below 125% of federal poverty guidelines ($19,088 for a single-person household in 2026).
Step 1: Gather Required Documentation
Before filing, compile evidence supporting your claimed material change. For income-based modifications, gather pay stubs from the past three months, federal and state tax returns for the past two years, documentation of any job loss or income reduction, and current benefit statements if receiving unemployment, disability, or Social Security. Courts require verification through official records, not simply assertions of changed circumstances.
For custody-based modifications, prepare a detailed overnight schedule documenting the actual parenting time arrangement. Include calendars, text messages confirming pickups and drop-offs, school records showing which parent handles daily responsibilities, and any informal custody modifications agreed upon between parents. Courts examine actual practice, not just the original custody order language.
Step 2: Complete Form CC-DR-006
Download Form CC-DR-006 from the Maryland Courts website at mdcourts.gov. The form requires identifying information for both parents, the case number from the original support order, the circuit court location, current support amounts, and a detailed explanation of the material change justifying modification. Be specific about dates, dollar amounts, and circumstances.
You must also complete a Financial Statement. Use Form CC-DR-030 (Child Support Guidelines Financial Statement) if the combined adjusted actual monthly income of both parents is $10,000 or less and neither party requests alimony. Use Form CC-DR-031 (General Financial Statement) if combined income exceeds $10,000 or if alimony is at issue. The financial statement requires disclosure of all income sources, monthly expenses, assets, and debts.
Step 3: File with the Circuit Court
File your completed forms with the Clerk of the Circuit Court that issued the original child support order. Pay the filing fee of $165-$312 or submit a fee waiver request (Form CC-DC-089) simultaneously. The clerk will assign a new case number or add the motion to your existing case, provide a stamped copy for your records, and schedule a hearing date.
After filing, you must serve the other parent with copies of all filed documents. Service may be accomplished through certified mail with return receipt requested, sheriff's service, or private process server. The other parent has 30 days to file a response. Keep proof of service for your records, as courts will not proceed without verification that the other parent received notice.
Step 4: Attend the Court Hearing
Maryland circuit courts schedule modification hearings within 90-180 days of filing. At the hearing, both parents present evidence supporting their positions. Bring original documents substantiating your claimed material change, completed child support guideline worksheets showing proposed recalculations, and any witnesses who can testify to relevant facts.
The court will evaluate whether you have proven a material change, recalculate support under the Maryland Child Support Guidelines, and issue a modified order if warranted. If both parents agree on modification terms, you may submit a consent order for the court's approval, potentially avoiding a contested hearing.
Child Support Administration Filing Option
Parents with cases administered through the Maryland Child Support Administration (CSA) may request modifications at no cost by contacting the agency at 1-800-332-6347. CSA handles approximately 340,000 child support cases statewide and provides free modification services for qualifying families. This option eliminates filing fees and court appearances for uncontested modifications.
To qualify for CSA services, at least one parent must be receiving or have received public assistance, or either parent must have requested CSA services. The agency will review documentation, calculate proposed modifications using the guidelines, and submit paperwork to the court on your behalf. Processing through CSA typically takes longer than private filing but costs nothing out of pocket.
Maryland Child Support Calculation Under the Guidelines
Maryland uses the Income Shares Model codified in Md. Code, Family Law §§ 12-201 through 12-204. This formula calculates child support by combining both parents' adjusted actual incomes, looking up the basic support obligation in the statutory schedule, and dividing that obligation proportionally based on each parent's income share.
How the Income Shares Model Works
The guidelines apply when combined parental income does not exceed $30,000 per month. Courts start with each parent's gross monthly income, then subtract certain allowable deductions including pre-existing child support obligations, pre-existing alimony obligations, and the new Multifamily Adjustment for children in the parent's current household.
Using the schedule in Md. Code, Family Law § 12-204(e), courts identify the basic child support obligation based on combined income and number of children. For example, parents with combined monthly adjusted actual income of $10,000 and two children would have a basic child support obligation of approximately $1,645 per month.
Each parent's share equals their percentage of combined income. If Parent A earns $6,000 (60%) and Parent B earns $4,000 (40%), Parent A is responsible for 60% of the basic obligation. When Parent B has primary custody, Parent A pays their 60% share directly. Additional expenses for health insurance premiums and work-related childcare are added to the basic obligation and divided using the same proportional split.
Shared Custody Calculations
When both parents have 92 or more overnights annually, courts use Worksheet B which credits each parent for expenses during their parenting time. The shared custody formula reduces the paying parent's obligation based on the percentage of time the child spends in their care. A parent with 40% of overnights (146 nights) receives greater credit than one with exactly 25% (92 nights).
The formula multiplies each parent's proportional share by 1.5 (the multiplier accounting for duplicated fixed costs in two households), then adjusts based on actual overnights. This calculation typically results in lower support amounts than sole custody arrangements with comparable incomes.
When Courts Deviate from Guidelines
Maryland courts may deviate from guideline calculations when application would be unjust or inappropriate. Under Md. Code, Family Law § 12-202(a)(2), courts must make written findings explaining any deviation and the amount support would have been under the guidelines.
Common deviation factors include: extraordinary medical needs not covered by insurance, educational expenses for special needs children, substantial income from the child (such as trust income or entertainment earnings), extremely high combined parental income exceeding $30,000 monthly, and financial obligations arising from prior marriages that affect ability to pay.
Timeline for Child Support Modification in Maryland
The modification process from filing to final order typically spans 90-180 days depending on court scheduling, case complexity, and whether the other parent contests the petition. Uncontested modifications where both parents agree to new terms move faster, often concluding within 90 days. Contested cases requiring evidentiary hearings and judicial findings take longer, sometimes exceeding 180 days.
Critical Timing: No Retroactive Modifications
Under Md. Code, Family Law § 12-104, Maryland courts cannot retroactively modify child support prior to the date of the filing of the motion for modification. This means any delay in filing costs money. If a parent loses their job in January but waits until July to file for modification, they cannot recover the January-through-July overpayment. The clock starts only when paperwork reaches the clerk's office.
This rule creates urgency for parents experiencing material changes. Courts will not provide relief for periods before filing, regardless of how compelling the circumstances. A parent who waited six months after a 50% income reduction would still be legally obligated for the original support amount during that entire waiting period.
Response Period and Hearing Scheduling
After filing, the other parent has 30 days to file a written response. If they contest the modification, the court schedules a hearing. Maryland circuit courts typically schedule family law hearings 60-120 days out depending on docket congestion. During this period, the original support order remains in effect. The filing parent must continue paying or receiving the original amount until the court issues a modified order.
Cases with represented parties on both sides often proceed more quickly due to attorneys' ability to negotiate settlements, file joint motions, and streamline hearing preparation. Self-represented parties may face additional delays navigating procedural requirements.
Common Mistakes to Avoid When Modifying Child Support
Parents frequently undermine their modification requests through avoidable errors. Understanding these pitfalls helps ensure a successful petition.
Stopping Payments Before Modification
Never reduce or stop child support payments without a court order. Even if you experience a 50% income reduction that clearly qualifies for modification, unilaterally reducing payments creates arrearages that accumulate interest at 10% annually under Maryland law. Courts can garnish wages, intercept tax refunds, suspend licenses, and hold parents in contempt for unpaid support. Always file for modification first and continue paying the original amount until the court orders otherwise.
Voluntary Income Reduction
Quitting a job or taking a lower-paying position to reduce support obligations typically backfires. Under Md. Code, Family Law § 12-201(b), courts may impute income to parents who are voluntarily unemployed or underemployed. The court considers education, work history, earning capacity, and reasons for the employment change. A parent who quits a $100,000 job to take a $40,000 position without legitimate justification may find support calculated on the original earning capacity.
Legitimate reasons for career changes include pursuing education to increase long-term earnings, health conditions preventing continuation in a demanding field, and family caregiving responsibilities. Document the reasons thoroughly and be prepared to explain why the change was necessary rather than merely advantageous for support calculations.
Insufficient Documentation
Material change claims require proof through official records. Courts reject modifications based on assertions without supporting documentation. Gather pay stubs, tax returns, termination letters, unemployment benefit statements, medical records, and custody calendars before filing. The burden of proof falls entirely on the party requesting modification.

What percentage income change is needed to modify child support in Maryland?
Maryland courts generally recognize an income change of 25% or more as sufficient to qualify for child support modification under Md. Code, Family Law § 12-104. This threshold applies to increases or decreases in either parent's income. Changes below 25% may still qualify if other material circumstances have changed, but are not guaranteed approval.
How long does child support modification take in Maryland?
The child support modification process in Maryland typically takes 90-180 days from filing to final order. Uncontested modifications where both parents agree may conclude within 90 days. Contested cases requiring evidentiary hearings and judicial findings often take 120-180 days or longer depending on court scheduling and case complexity.
Can I modify child support without going to court in Maryland?
Yes, parents with cases administered through the Maryland Child Support Administration (CSA) can request modifications at no cost by calling 1-800-332-6347. CSA reviews documentation, calculates proposed modifications, and submits paperwork on your behalf. This option eliminates filing fees and often avoids court appearances for uncontested modifications.
Will Maryland modify child support retroactively?
No. Under Md. Code, Family Law § 12-104, Maryland courts cannot modify child support retroactively before the date the motion was filed. If you experience a job loss in January but wait until July to file, you cannot recover overpayments made from January through June. File promptly after any material change occurs.
What happens if I stop paying child support while waiting for modification?
Continue paying the full original amount until a court issues a modified order. Unilaterally reducing payments creates arrearages that accumulate interest at 10% annually. Maryland enforces unpaid support through wage garnishment, tax refund interception, license suspension, passport denial, and contempt proceedings including potential incarceration.
Does custody change affect child support modification in Maryland?
Yes. Custody changes crossing the 92-overnight threshold (25% of the year) constitute material changes warranting support modification. When a parent's overnight percentage increases to 92 or more annually, courts must recalculate using shared custody Worksheet B under Md. Code, Family Law § 12-204(d), typically resulting in lower support obligations.
Can I modify child support if my ex got a raise?
Yes. An income increase of 25% or more in either parent's earnings qualifies as a material change. If the paying parent's income increased significantly since the original order, the receiving parent can file Form CC-DR-006 requesting increased support. Similarly, if the receiving parent's income increased substantially, the paying parent may request a reduction.
What forms do I need to modify child support in Maryland?
You need Form CC-DR-006 (Motion to Modify Child Support) plus either Form CC-DR-030 (Financial Statement for Child Support Guidelines) or Form CC-DR-031 (General Financial Statement) depending on income levels. Use CC-DR-030 when combined monthly income is $10,000 or less; use CC-DR-031 when combined income exceeds $10,000 or alimony is requested.
How does Maryland's new Multifamily Adjustment affect child support modifications?
Maryland's 2026 Multifamily Adjustment under House Bill 275 allows parents supporting additional children in their household to deduct 75% of those support obligations when calculating adjusted actual income. This change, effective October 1, 2025, may constitute grounds for modification if it significantly affects the guideline calculation compared to the original order.
