How Maryland child support is calculated

Maryland utilizes an Income Shares Model to calculate child support. The process begins by determining each parent's actual monthly income, which includes wages, bonuses, and other benefits. From this, an adjusted actual income is calculated by subtracting pre-existing child support payments, alimony paid, and an allowance for other dependent children living with the parent. These adjusted incomes are then combined and used with a Guidelines chart to establish a basic child support obligation. Further adjustments are made for health insurance costs, work-related childcare expenses, and extraordinary medical expenses. A self-support reserve is also applied to ensure the paying parent retains a minimum income. The final total child support obligation is then proportionally divided between the parents based on their adjusted actual incomes, with the non-custodial parent responsible for their share.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Parenting time shifts

If the custody schedule changes significantly, support can be recalculated under Maryland guidelines.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.

Common questions

What people ask about child support

How long does a divorce take in Maryland?

An uncontested divorce in Maryland can take anywhere from a couple of months to a year or more, depending on the complexity of the case (e.g., presence of children, property issues). Uncontested cases with all issues resolved typically finalize in one to four months after filing.

Do I need a lawyer to get divorced in Maryland?

While it is possible to represent yourself in a Maryland divorce, especially in uncontested cases, legal advice is highly recommended. Attorneys can help navigate complex issues like property division, alimony, and child custody, ensuring all legal requirements are met and protecting your interests.

Is Maryland a no-fault divorce state?

Yes, as of October 1, 2023, Maryland is a no-fault divorce state. The grounds for absolute divorce are 6-month separation, irreconcilable differences, or mutual consent. Fault-based grounds are no longer available.

How is property divided in Maryland divorce?

Maryland follows the principle of equitable distribution. This means marital property is divided fairly, but not necessarily equally (50/50), between the spouses. The court considers various factors, including monetary and non-monetary contributions, economic circumstances, and the duration of the marriage.

What is the difference between limited and absolute divorce in Maryland?

Prior to October 1, 2023, Maryland recognized both limited and absolute divorce. A limited divorce did not terminate the marriage but allowed spouses to live apart under court-approved terms. As of October 1, 2023, the concept of limited divorce was eliminated, and only absolute divorce, which legally ends the marriage, is available.
