Support in Delaware (2026)

The Melson Formula: Delaware’s Unique Child Support Model

Delaware is one of only three states (along with Hawaii and Montana) that uses the Melson Formula to calculate child support obligations. Developed by Delaware Family Court Judge Elwood F. Melson Jr., this approach is a sophisticated refinement of the income shares model that distinguishes Delaware’s child support system from the simpler models used in most other states.

The Melson Formula operates in three steps, each designed to address a different policy concern:

Step 1: The Self-Support Reserve

The court first ensures that each parent retains enough income to meet their own basic needs. If a parent’s net income falls below the self-support threshold, the support obligation is reduced or eliminated. This step prevents the support calculation from pushing a parent into poverty — a protection that many other states’ simpler income shares models do not provide.

Step 2: The Primary Support Obligation

The court calculates the child’s basic needs and allocates the cost between the parents based on their respective net incomes, after the self-support reserve has been subtracted. This step functions similarly to other income shares models: the child’s basic needs are quantified, and each parent is responsible for their proportionate share.

Step 3: The Standard of Living Adjustment (SOLA)

If either parent has income remaining after covering their self-support reserve and primary support share, a percentage of the excess is allocated to benefit the child, ensuring that the child shares in the parent’s higher standard of living. This step is what most distinguishes the Melson Formula from other models — it recognizes that children should benefit from their parents’ financial success, not just have their basic needs met.

The guidelines are established under 13 Del. C. Section 514.

Why the Melson Formula Matters

The practical significance of the Melson Formula is that it produces support amounts that respond to the financial realities of both parents more precisely than simpler models. For low-income parents, the self-support reserve provides meaningful protection. For higher-income parents, the SOLA ensures that children benefit proportionally from greater parental resources.

This three-step approach also means that Melson Formula calculations are more complex than standard income shares calculations, which can make them harder to estimate without professional assistance or a detailed calculator. Parents navigating Delaware child support should expect a more involved calculation process than they would encounter in most other states.

Deviation Criteria

The Melson Formula produces a presumptive support amount, but the court may deviate when strict application would be unjust. Permissible grounds for deviation include:

• Extraordinary medical expenses not covered by insurance
• Special needs or educational expenses of the child
• The financial resources and needs of each parent
• The standard of living the child would have enjoyed had the marriage continued
• Child care costs related to employment or education
• Shared or split physical custody arrangements
• Pre-existing support obligations for other dependents
• Any other relevant factor affecting the best interests of the child

When the court deviates, it must state the reasons and the amount of the guideline calculation on the record.

Spousal Support (Alimony) in Delaware

Delaware courts award alimony under 13 Del. C. Section 1512. The statute directs the court to consider a set of specific factors:

• The financial resources of the party seeking alimony and their ability to meet needs independently
• The time necessary to acquire sufficient education or training for appropriate employment
• The standard of living established during the marriage
• The duration of the marriage
• The age, physical and emotional condition of both parties
• The contribution of the party seeking alimony to the education, training, or increased earning power of the other party
• The ability of the respondent to meet their own needs while paying alimony
• The tax consequences to each party
• Whether either party forgone or postponed economic, education, or employment opportunities during the marriage

Delaware recognizes temporary alimony (during the pendency of proceedings), rehabilitative alimony (to enable a spouse to become self-supporting through education or training), and permanent alimony (in longer marriages or when rehabilitative alimony is insufficient due to age, health, or other limitations).

The “Forgone Opportunities” Factor

Delaware’s alimony statute includes a provision that specifically addresses sacrificed career and educational opportunities. Under 13 Del. C. Section 1512, the court must consider whether either party forgone or postponed economic, education, or employment opportunities during the marriage.

This factor is particularly significant in marriages where one spouse left the workforce, declined a promotion, or delayed education to support the family or the other spouse’s career. It ensures that the economic sacrifice of the supporting spouse is recognized in the alimony calculation, even when that sacrifice may not be captured by traditional factors like current earning capacity.

Modification of Support Orders

Either party may petition for modification of child support or alimony by demonstrating a substantial and continuing change in circumstances that renders the existing order unreasonable. Under 13 Del. C. Section 1519, the change must not be self-created. Common grounds include significant income changes, job loss, changes in the child’s needs, or changes in custody arrangements. The Delaware Family Court reviews the same statutory factors used in the original order when evaluating a modification request.

Enforcement

Delaware employs a range of enforcement mechanisms when a parent or former spouse fails to comply with a support order:

• Income withholding (wage garnishment)
• Interception of state and federal tax refunds
• Suspension of driver’s, professional, and recreational licenses
• Contempt of court, which may result in fines or incarceration
• Liens on real and personal property
• Passport denial for arrearages exceeding $2,500
• Credit bureau reporting
• Bank account levies

The Delaware Division of Child Support Services assists custodial parents in establishing, modifying, and enforcing child support orders.

When to Seek Legal Guidance

Delaware’s Melson Formula is more complex than the child support models used in most states, and the alimony analysis involves significant judicial discretion. Whether you are establishing a new support order, seeking a modification, or dealing with non-payment, consider scheduling a free consultation with a family law attorney to understand your rights and options.

Frequently Asked Questions

What child support model does Delaware use?

Delaware is one of only three states that uses the Melson Formula, a refined income shares model developed by Delaware Family Court Judge Elwood F. Melson Jr. Under 13 Del. C. Section 514, the formula operates in three steps: first ensuring each parent retains a self-support reserve, then calculating the child’s basic needs, and finally applying a standard of living adjustment (SOLA) so the child shares in excess parental income.

Can child support be modified in Delaware?

Yes. Under 13 Del. C. Section 1519, either parent may petition for modification by showing a substantial and continuing change in circumstances that renders the existing order unreasonable. The change must not be self-created. Common grounds include significant income changes, job loss, or changes in custody arrangements.

What types of alimony does Delaware recognize?

Delaware recognizes temporary alimony (during proceedings), rehabilitative alimony (to enable a spouse to become self-supporting through education or training), and permanent alimony (for longer marriages or when the recipient cannot achieve self-sufficiency due to age or health). Under 13 Del. C. Section 1512, the court weighs the standard of living during the marriage, the duration of the marriage, and each party’s earning capacity and contributions.

How does the Melson Formula’s self-support reserve work?

The self-support reserve ensures that each parent retains enough income to meet their own basic needs before a child support obligation is imposed. If a parent’s net income falls below the self-support threshold, the support obligation is reduced or eliminated. This distinguishes Delaware’s system from simpler income shares models that do not build in this protection.

What is the Standard of Living Adjustment (SOLA)?

The SOLA is the third and most distinctive step of the Melson Formula. After each parent’s self-support reserve is protected and the child’s basic needs are covered, a percentage of each parent’s remaining income is allocated to the child. This ensures that children benefit from their parents’ financial success beyond just having basic needs met — a feature that most other states’ support models do not include.

What does the “forgone opportunities” factor mean for alimony in Delaware?

Under 13 Del. C. Section 1512, the court must consider whether either spouse forgone or postponed economic, education, or employment opportunities during the marriage. This is significant for spouses who left careers, declined promotions, or delayed education to support the family. The provision ensures that these sacrifices are recognized when determining alimony, even if they do not show up in traditional measures like current earning capacity.
