Delaware uses the Melson Formula to determine child support obligations. Delaware uses the Melson Formula, one of only three states to do so. The Melson Formula is more complex than Income Shares — it first ensures each parent can meet their own basic needs (self-support reserve), then funds the children's primary support needs, and finally distributes any remaining income proportionally. This protects low-income parents from being left with insufficient income.
Delaware's Melson Formula has three steps: (1) calculate self-support reserve for each parent; (2) determine primary support for children; (3) apply Standard of Living Adjustment (SOLA) to share remaining income proportionally. Delaware updates its Melson Formula tables periodically.
Delaware Family Court provides child support calculation worksheets. The Delaware Division of Child Support Services has resources at dcss.delaware.gov.
Alex earns $5,500/month gross income. Jordan earns $3,200/month. They have 2 children in Delaware. Alex has primary custody; Jordan has standard visitation (every other weekend, approximately 73 overnights/year).
This example uses approximate calculations. Actual Delaware child support requires the official Melson Formula worksheet or software and should be verified with a licensed family law attorney or the court.
Both Parents' Income
Delaware's Melson Formula combines both parents' incomes to determine the total family resources available for the children. A higher combined income results in higher support — reflecting the idea that children should benefit from the family's overall financial resources regardless of which parent they primarily reside with.
Custody and Parenting Time
Delaware adjusts child support based on the amount of parenting time each parent has. More overnight time with the paying parent generally reduces the support obligation — reflecting that the paying parent directly absorbs the children's costs during their parenting time. Delaware's Melson Formula has three steps: (1) calculate self-support reserve for each parent; (2) determine primary support for children; (3) apply Standard of Living Adjustment (SOLA) to share remaining income proportionally.
Health Insurance and Childcare
Health insurance premiums for the children and work-related childcare costs are added to the basic child support obligation in Delaware. The cost is typically split proportionally based on each parent's share of combined income. These add-ons can significantly increase the total support obligation, particularly in cases with high childcare or health insurance costs.

Delaware uses the Melson Formula to calculate child support. Delaware uses the Melson Formula, one of only three states to do so. The guideline amount is the starting point, but courts may deviate based on special circumstances such as a child's extraordinary medical needs, travel costs for visitation, or significantly different financial situations from the guideline assumptions. Always confirm your specific calculation with a Delaware family law attorney.
Delaware uses a complex Melson Formula that considers each parent's self-support reserve before allocating income to children's support. Courts may also impute income to a parent who is voluntarily underemployed or unemployed without good cause — meaning they may be held to what they could earn rather than what they actually earn.
No. In Delaware, shared custody reduces but does not eliminate child support in most cases. When both parents share custody equally, Delaware typically uses an offset method where each parent's guideline support is calculated and the higher earner pays the difference. The goal is to ensure the children maintain a similar standard of living in both households. If incomes are nearly equal, the resulting payment may be very small, but it rarely drops to zero unless incomes are identical.
In Delaware, child support generally continues until the child reaches the age of majority (typically age 18), graduates from high school, or is otherwise emancipated — whichever occurs later up to the state maximum. Courts may also continue support for adult disabled children who cannot support themselves. Support does not automatically end — the paying parent must file for termination when the child ages out or becomes emancipated.
Yes. Delaware child support can be modified when there is a substantial change in circumstances. Most states, including Delaware, require that the new calculated amount differ from the existing order by at least 15% — or that three years have passed since the order was entered, triggering an automatic review. Changes that typically qualify include significant income changes for either parent, a change in custody arrangement, a child's new medical needs, or loss of health insurance coverage. Modifications require filing a motion with the family court — the original order remains in effect until a new order is entered.
