Delaware Child Support Calculator & Guide (2025)

Overview of Delaware Child Support

Delaware is unique as the birthplace of the Melson Formula, developed by Judge Elwood F. Melwood. This three-step formula is used under Delaware Code Title 13, §514 and takes a fundamentally different approach from the Income Shares Model used by most states.

The Melson Formula prioritizes ensuring each parent can meet their own basic needs before calculating child support. It then applies a standard of living adjustment so that children share in their parents' financial prosperity. This approach is considered one of the most equitable methods for determining child support.

How Child Support Is Calculated in Delaware (Melson Formula)

The Delaware Melson Formula works in three distinct steps:

1. Step 1 - Primary Support Need: Each parent is allocated a primary support need of $1,100/month (2024). This amount is reserved for the parent's own basic living expenses and is not available for child support calculations.
2. Step 2 - Basic Child Support: After subtracting each parent's primary support need, the remaining income is used to calculate child support. The basic support amount is determined from the state schedule based on the number of children and combined remaining income.
3. Step 3 - Standard of Living Adjustment: If income remains after steps 1 and 2, a standard of living adjustment is applied. This ensures that children benefit from parents' additional income and maintain a standard of living consistent with parental resources.

Key Factors in Delaware Calculations

Both Parents' Income

The Melson Formula considers both parents' incomes at every step. Each parent's income is evaluated individually to determine their primary support need, and then both parents' remaining incomes are combined for the support calculation.

Health Insurance and Childcare

Health insurance premiums for the child and childcare costs are added to the basic support obligation. These expenses are allocated between the parents in proportion to their respective incomes.

Court Discretion

Delaware courts may deviate from the Melson Formula results for good cause shown. The court considers the specific circumstances of each case, including the child's special needs, extraordinary expenses, and any other relevant factors.

Minimum and Maximum Amounts

Minimum: Delaware does not have a fixed statutory minimum. The Melson Formula's built-in protections (primary support need and poverty level reserve) effectively create a floor based on the obligor's income level.

Maximum: There is no hard cap. The standard of living adjustment in Step 3 means that support increases proportionally as parents earn more, ensuring children benefit from higher parental income.

Modification and Enforcement

Modification

Delaware allows modification when:

• There has been a substantial change in circumstances
• A significant increase or decrease in either parent's income
• A change in custody arrangements
• A change in the child's needs

Enforcement

The Delaware Division of Child Support Services enforces orders through:

• Income withholding from paychecks
• Tax refund interception (federal and state)
