Delaware Child Support Guidelines

Melson Formula ModelLast updated: 2024-01-01

Delaware uses the Delaware Melson Formula (Family Court Civil Rule 52(c)) to determine child support obligations. The Melson Formula is an advanced version of the Income Shares model that first ensures each parent can meet their own basic needs through a self-support reserve before allocating child support. It also provides for a standard of living adjustment when income exceeds basic needs.

Delaware has several distinctive features in its child support system. Delaware developed the Melson Formula (named after Judge Elwood Melson) — one of only three states using this model. The formula has three steps: (1) ensure each parent can meet their own basic needs, (2) meet children's basic needs, (3) share any remaining income proportionally. The Standard of Living Adjustment (SOLA) is unique to Melson — it shares surplus income above basic needs with children.

Delaware bases calculations on net income — meaning income after mandatory deductions like taxes, Social Security, and Medicare. This gives a more accurate picture of each parent's take-home pay. The self-support reserve in Delaware is $1,250/month, ensuring the paying parent retains enough income to cover basic living expenses.

How Delaware Calculates Child Support

Delaware follows a 6-step process under the Delaware Melson Formula (Family Court Civil Rule 52(c)):

  1. 1

    Calculate each parent's net monthly income after taxes and mandatory deductions

  2. 2

    Step 1 — Primary Support: Subtract the self-support reserve ($1,250) from each parent's net income. If income is below the reserve, a minimal order may apply

  3. 3

    Step 2 — Basic Child Support: From each parent's remaining income, calculate their share of the children's primary support needs using the per-child allowance

  4. 4

    Step 3 — Standard of Living Adjustment (SOLA): Any income remaining after Steps 1 and 2 is shared with the children based on a percentage to maintain their standard of living

  5. 5

    Add each parent's pro-rata share of childcare and unreimbursed medical expenses

  6. 6

    The non-custodial parent's total from Steps 2 and 3, plus their share of additional costs, is the support order

Custody Time Adjustments in Delaware

Delaware recognizes "Shared Placement" when the non-custodial parent has the children for at least 110 overnights per year (approximately 30% of the time). When this threshold is met, the standard child support formula is adjusted to reflect the increased direct expenses borne by both parents.

Under the Melson Formula used in Delaware, shared custody adjustments apply after the basic needs and standard of living calculations. The formula accounts for duplicated fixed costs (like maintaining two bedrooms) while reducing variable costs proportionally to the time spent with each parent.

Below 110 overnights, Delaware generally treats the arrangement as a sole custody situation with standard visitation, and no custody time adjustment is applied to the child support calculation.

Frequently Asked Questions About Delaware Child Support

What is the Melson Formula?

The Melson Formula is a three-step child support calculation developed in Delaware. Unlike simple income shares, it first ensures each parent can meet their own basic needs (self-support reserve), then calculates children's basic needs, then shares any surplus income with the children through a Standard of Living Adjustment (SOLA). Only Delaware, Hawaii, and Montana use this approach.

What is the self-support reserve in Delaware?

Delaware's self-support reserve is approximately $1,250 per month. This amount is protected from the child support calculation to ensure the paying parent can meet their own basic living expenses.

What is the SOLA in Delaware child support?

SOLA stands for Standard of Living Adjustment. After basic needs are met for both the parents and children, any remaining income is shared with the children through the SOLA. This ensures children benefit from their parents' higher standard of living.

How to Reduce Child Support Costs in Delaware

While child support is determined by Delaware's guidelines, there are legitimate ways to ensure your obligation is calculated fairly.

Increase Parenting Time

In Delaware, more overnights with your children can reduce your support obligation. Document actual time spent and request a formal custody modification if needed.

Ensure Accurate Income Reporting

Both parents' incomes must be reported accurately. Verify that bonuses, overtime, and variable income are averaged correctly over the appropriate period.

Claim All Allowable Deductions

Delaware allows deductions for items like mandatory retirement contributions, union dues, and health insurance premiums. Make sure all qualifying deductions are included.

Request a Modification When Eligible

If your income has decreased by 15-25% or more, you may qualify for a modification. File promptly — changes are typically not retroactive before the filing date.

Account for Other Children

If you have other children you're legally obligated to support, this can be factored into the calculation as a deduction in most states.

Review Healthcare & Childcare Costs

Ensure shared expenses like health insurance and childcare are divided proportionally. If costs have changed, update the court.

Common Questions About Delaware Child Support

What is the average child support payment in Delaware?

Average child support in Delaware varies widely based on income, number of children, and custody arrangement. Using the Melson Formula model, a typical case with combined income of $6,000/month and one child might result in $800-$1,200/month. Use our calculator above for a personalized estimate.

How do I file for child support in Delaware?

In Delaware, you can file for child support through your local family court or the state's child support enforcement agency. You'll need to provide income documentation, custody information, and details about the children. Many courts offer self-help resources and forms online.

Can I modify child support in Delaware?

Yes, Delaware allows modifications when there is a substantial change in circumstances, such as a significant income change (typically 15-25%), change in custody, or change in the child's needs. File a motion with the court that issued the original order.

Does Delaware enforce child support across state lines?

Yes, under the Uniform Interstate Family Support Act (UIFSA), Delaware cooperates with all other states to enforce child support orders. If the other parent moves to a different state, enforcement can still be pursued through interstate cooperation.

How does shared custody affect child support in Delaware?

When both parents have significant parenting time, Delaware applies a shared custody adjustment. This typically reduces the obligation because both parents directly cover expenses during their time. The threshold and formula vary, so use our calculator to model different custody scenarios.
