Child Support in Delaware

Income shares Model

Delaware uses the Melson Formula, a variation of the Income Shares model, for calculating child support. The Melson Formula is unique to Delaware and accounts for: (1) a self-support allowance for each parent before determining income available for support; (2) the children's primary support needs based on both parents' combined adjusted income; and (3) a Standard of Living Adjustment (SOLA) that allows children to benefit from parents' higher income after basic needs are met. Form 509 is the official worksheet. The formula considers both parents' net incomes after allowable deductions, health insurance premiums, and childcare costs.

Mandatory Parenting Course

Delaware requires both parents to complete a parenting education course when filing for divorce with minor children.

Under Delaware Family Court Rule, both parents in divorce cases involving minor children under 18 must attend a certified parenting education course (typically 6-8 hours). Each county operates its own program with fees capped at $100 per parent (usually around $50). The course educates parents about the effects of divorce on children and strategies to minimize harm.

Typical cost: $50

What Goes in a Parenting Plan?

A comprehensive parenting plan should cover:

Regular Parenting Schedule

Week-by-week schedule of where the child lives and when transitions occur.

Holiday & Vacation Schedule

How holidays, school breaks, and vacation time are divided between parents.

Decision-Making Authority

Who makes decisions about education, healthcare, extracurriculars, and religious upbringing.

Communication Rules

How the child communicates with the non-custodial parent (phone, video calls, etc.).

Transportation & Exchange

Who handles pickups/dropoffs and where exchanges occur.

Dispute Resolution

How disagreements about the parenting plan will be resolved (mediation first, then court).

Relocation Rules

Notice requirements and procedure if either parent wants to move.

Tips for Protecting Your Children During Divorce

1.

Never speak negatively about the other parent in front of your children. It puts them in the middle and can harm your custody case.

2.

Maintain routines. Keep school, activities, and daily routines as consistent as possible during the transition.

3.

Communicate openly with your children in age-appropriate ways. Let them know the divorce is not their fault.

4.

Consider counseling. A child therapist can help children process their emotions during this time.
