Understanding Delaware's Child Support Formula
Delaware is one of only three states, alongside Hawaii and Montana, that uses the Melson Formula, developed by former Delaware Family Court Judge Elwood Melson in the 1970s. Unlike the Income Shares model, the Melson Formula begins by establishing a self-support reserve: a minimum income that each parent needs to cover basic personal expenses. Child support is calculated only on income above this reserve, ensuring neither parent is pushed below a subsistence level by the support obligation. As parental incomes rise beyond their own basic needs, a Standard of Living Adjustment (SOLA) is applied so that children benefit proportionally from higher household income. The Melson Formula is more mathematically complex than the Percentage or Income Shares models, but it builds in protections that the simpler formulas do not. In practice, Delaware courts calculate the reserve amounts based on current poverty guidelines and update them periodically.
Sample Delaware Child Support Calculation
Scenario: Parent A (paying parent) earns $5,500/month gross. Parent B earns $3,000/month gross. 1 child. Parent A has 20% parenting time.
The final Delaware order will also factor in any health insurance premiums and work-related childcare costs. Parenting time above 20% typically generates a parenting time credit that can reduce the amount further.
Delaware Child Support, Frequently Asked Questions
Why does Delaware use the Melson Formula instead of Income Shares?
Delaware adopted the Melson Formula because it explicitly protects each parent's minimum self-support needs before any obligation is calculated. The standard Income Shares model does not include this built-in self-sufficiency reserve, which can sometimes produce obligations that leave a low-income paying parent unable to cover their own basic costs. The Melson approach is more complex to compute but more equitable across wide income ranges.
What is the average child support payment in Delaware?
Child support awards in Delaware typically range from $400–$900/month based on current data. The actual amount varies significantly depending on both parents' incomes, the number of children, custody arrangements, and whether costs like health insurance or childcare are included in the order. Higher income households and multiple children will produce awards above this range.
Can a Delaware judge order a different amount than the calculator shows?
Yes. The Delaware guidelines produce a presumptive amount — the starting point, but a judge can deviate from it when following the guidelines would be unjust or inappropriate in a specific case. Common reasons for deviation include extraordinary medical or educational expenses, one parent directly paying significant healthcare premiums, a parent's substantial assets or non-wage income, the needs of children from other relationships, or significant travel costs related to custody exchanges.
How do you modify a child support order in Delaware?
Either parent can petition the Delaware court to modify an existing child support order when there has been a substantial change in circumstances. This typically means a significant change in either parent's income (usually 15–20% or more), a change in custody or parenting time, the child developing extraordinary medical or educational needs, or a change in the cost of health insurance. Most states, including Delaware, also allow automatic review every three years if either party requests it, even without proving a substantial change.
When does child support end in Delaware?
In Delaware, child support terminates at: Age 18 or high school graduation, whichever is later. The governing law is 13 Del. C. § 514, administered by the DCSE (Division of Child Support Enforcement). If you have an existing order and believe your child is approaching the termination age, contact DCSE (Division of Child Support Enforcement) or your family law attorney to confirm the specific end date and ensure a formal termination order is entered.
