Delaware law mandates that every child support order address health insurance coverage for minor children. Under 13 Del. C. § 514 and Family Court Civil Rules 500-510, courts must order one or both parents to provide medical support when employer-sponsored insurance costs no more than 5% of gross income. The state uses the Melson Formula to calculate support obligations, with health insurance premiums factored into the total obligation and divided proportionally between parents based on income. Filing fees for child support matters range from $0 (DCSS clients) to $175 for divorce petitions that include support, with modifications costing approximately $25 for private cases as of March 2026.

How Delaware Courts Order Health Insurance in Child Support Cases
Delaware Family Court requires that all child support orders include a medical support provision addressing health insurance coverage for minor children. Under 13 Del. C. § 514, courts must order either or both parents to provide health insurance when coverage is accessible and reasonably priced, defined as costing no more than 5% of the obligated parent's gross income. The court issues a National Medical Support Notice (NMSN) to the employer, which triggers mandatory enrollment within 20 business days regardless of open enrollment periods. Parents who fail to maintain ordered coverage face contempt charges and potential modification of their support obligations.
The Delaware Division of Child Support Services (DCSS) enforces medical support orders through income withholding. When a court orders health insurance, the employer must deduct premium costs directly from the parent's wages alongside any cash child support obligation. This automatic withholding ensures consistent coverage without requiring monthly decisions from the obligated parent.
The Melson Formula and Health Insurance Premium Calculations
Delaware calculates child support using the Melson Formula, a unique three-step methodology codified in Family Court Civil Rules 500-510 that only Delaware, Hawaii, and Montana utilize. The formula first ensures each parent retains a $1,570 monthly self-support allowance for 2026, then calculates primary support using the formula ($410 per child plus $370), and finally applies a Standard of Living Adjustment (SOLA) ranging from 12% for one child to 21% for three children. Health insurance premiums for children represent an add-on expense that the court allocates between parents proportionally based on their respective incomes.
The premium amount attributable to children equals the difference between employee-only coverage and employee-plus-dependents coverage. For example, if a parent pays $200 monthly for individual coverage and $450 monthly for family coverage, the children's allocable premium is $250. This $250 is added to the basic support obligation and divided between parents according to their income percentages. A parent earning 60% of combined income would bear $150 of this cost, while the other parent would bear $100.
Health Insurance Premium Calculation Example
| Factor | Parent A | Parent B |
|---|---|---|
| Gross Monthly Income | $5,000 | $3,500 |
| Income Percentage | 59% | 41% |
| Children's Premium Share | $147.50 | $102.50 |
| Monthly Cash Support | $412.50 | $287.50 |
| Total Monthly Obligation | $560.00 | $390.00 |
National Medical Support Notice: Employer Obligations
When Delaware Family Court orders health insurance child support Delaware, the Division of Child Support Services issues a National Medical Support Notice (NMSN) to the obligated parent's employer within 2 business days of the order. The DCSS employer information page outlines that employers must respond within 20 business days by either enrolling the child in available health coverage or completing the Employer Response form explaining why enrollment cannot occur. Employers who fail to comply face penalties under 13 Del. C. § 2214.
Employers must enroll children without waiting for open enrollment periods. Delaware law specifically prohibits employers from denying immediate enrollment based on seasonal restrictions. Once enrolled, the employer cannot terminate the child's coverage unless the parent provides written proof that the support order is no longer in effect or that the child has enrolled in comparable coverage elsewhere. The NMSN takes priority over all other legal processes against income except federal tax liens.
When Health Insurance is Considered Unaffordable
Delaware establishes two critical thresholds for determining whether employer-sponsored health insurance is reasonably priced or unaffordable. Insurance is considered reasonable when the employee's share of premiums for adding children to coverage costs 5% or less of gross income. Coverage becomes presumptively unaffordable when family premiums exceed 10% of the parent's gross income. Between these thresholds, courts exercise discretion based on the specific circumstances.
When neither parent has access to affordable employer coverage, Delaware courts may order alternative arrangements. The court can require one or both parents to obtain coverage through the Health Insurance Marketplace (healthcare.gov), order cash medical support to cover unreimbursed expenses, or direct enrollment in Medicaid or the Delaware Healthy Children Program (DHCP) if children qualify. Cash medical support covers deductibles, copays, and expenses for dental, vision, and orthodontic care not included in standard health insurance.
Delaware Healthy Children Program: CHIP Coverage
Delaware's Children's Health Insurance Program, called the Delaware Healthy Children Program (DHCP), provides health coverage for uninsured children in families earning between Medicaid limits and 217-218% of the Federal Poverty Level (approximately $51,516 annually for a family of four in 2026). Monthly premiums range from $15 to $25 per family depending on income, covering all eligible children in the household. A quarterly pay-ahead discount allows families to pay three months and receive the fourth month free.
Children qualify for DHCP if they are under 19, reside in Delaware, are U.S. citizens or qualified non-citizens, lack health insurance covering doctor visits and hospital stays, and are not dependents of Delaware state employees. Standard Medicaid covers children in families earning up to 138% FPL (approximately $2,203 monthly for a single parent with one child) with no premium or asset test.

How Medical Support Affects Child Support Calculations
Medical support obligations in Delaware directly impact the monthly child support calculation through three mechanisms under the Melson Formula. First, health insurance premiums paid for children reduce the paying parent's net income available for basic support. Second, the children's allocable premium (difference between individual and family coverage costs) is added as a Line 12B expense on the calculation worksheet. Third, the total obligation is then divided between parents proportionally based on income percentages.
The Delaware Family Court child support calculator requires parents to input health insurance premium costs for children alongside gross monthly incomes, work-related childcare expenses, and the number of overnights each parent has per year. The calculator automatically applies the 2026 Melson Formula values, including the $1,570 self-support allowance and SOLA percentages. Courts may deviate from calculated amounts when health insurance arrangements create unusual circumstances, but deviations require written justification.
Modifying Medical Support Orders
Delaware permits modification of child support orders, including medical support provisions, when circumstances change significantly. Under Family Court Rule 52(c), parents may file a Petition for Modification (Form 342) if two-and-a-half years have passed since the last order, or sooner if a substantial change in circumstances exists. Modification will only be granted if the recalculated support amount differs from the current order by 10% or more.
Substantial changes justifying medical support modification include: loss or gain of employer-sponsored health insurance, significant premium increases or decreases, changes in a child's medical needs requiring different coverage, one parent becoming eligible for coverage through a new employer, or a child aging out of a parent's policy. DCSS clients pay no filing fee for modifications, while private cases pay approximately $25 as of March 2026. Parents demonstrating financial hardship can request fee waivers through an Affidavit in Support of Application to Proceed In Forma Pauperis if their income falls at or below 125% of federal poverty guidelines.
Enforcement of Medical Support Orders
Delaware Family Court enforces medical support orders through multiple mechanisms. When a parent ordered to provide insurance fails to enroll children, DCSS can contact the employer directly with a National Medical Support Notice. Employers who refuse to comply face civil penalties under 13 Del. C. § 2214. Courts may also find non-compliant parents in contempt, resulting in fines, wage garnishment adjustments, or incarceration for willful violations.
Parents who allow health insurance coverage to lapse face retroactive liability for all medical expenses incurred during the coverage gap. The custodial parent can seek reimbursement through Family Court, and the court may modify the support order to include cash medical support going forward. Delaware law provides no statute of limitations on child support enforcement, meaning parents remain liable for unpaid medical support obligations indefinitely regardless of when the expenses occurred.
Unreimbursed Medical Expenses: Division Between Parents
Beyond health insurance premiums, Delaware child support orders typically address unreimbursed medical expenses including deductibles, copays, coinsurance, and costs for services not covered by insurance such as dental, vision, and orthodontic care. Courts generally allocate these expenses proportionally between parents based on income percentages, consistent with the Melson Formula approach. A parent earning 65% of combined income would pay 65% of a $500 dental bill not covered by insurance.
Parents must exchange financial information annually under 13 Del. C. § 514, and this includes documentation of unreimbursed medical expenses. The paying parent typically has 30 days after receiving documented proof of expenses to reimburse their share. Failure to pay can be enforced through the same contempt mechanisms used for regular child support arrears. Delaware courts increasingly include specific language in support orders detailing the process for submitting and paying unreimbursed expenses.
COBRA Coverage After Divorce
When a parent loses employer-sponsored health insurance due to divorce, COBRA (Consolidated Omnibus Budget Reconciliation Act) allows continuation of coverage for up to 36 months. COBRA premiums are typically 102% of the full group rate (the former employer no longer subsidizes costs), making this option expensive. Delaware courts consider COBRA a temporary bridge rather than a long-term solution, often ordering the parent to obtain alternative coverage within 90 days of divorce finalization.
Children covered under a stepparent's policy before divorce may qualify for COBRA continuation if they lose coverage due to the divorce. The custodial parent must notify the plan administrator within 60 days of the divorce to elect COBRA coverage. Delaware child support orders should specify which parent bears COBRA premium costs during the transition period, with most courts allocating this expense proportionally or ordering the parent with access to new employer coverage to transition children as quickly as possible.
Health Insurance Considerations in Custody Arrangements
Custody arrangements directly impact health insurance decisions in Delaware child support cases. When children split time between households in different geographic areas, courts must ensure insurance provides accessible coverage at both locations. Insurance is considered accessible under Delaware law only if primary medical services are available within a reasonable distance from the child's residence. A parent with a plan covering only New Castle County providers may be ordered to obtain supplemental coverage or pay for out-of-network care when children live in Sussex County.
Joint custody arrangements require clear protocols for which parent manages health insurance claims, maintains prescription records, and communicates with healthcare providers. Delaware courts often designate the parent carrying insurance as the "insurance administrator" responsible for filing claims and providing insurance cards. The other parent receives copies of all documents and must have access to schedule appointments and communicate with doctors without requiring the administering parent's involvement.
