The formula is based on both parents' combined net income multiplied by a percentage that varies depending on income level and the number of children. Each parent's share is proportional to their respective income. The court may adjust the guideline amount based on special circumstances such as extraordinary medical expenses or approximately equal parenting schedules.

Health Insurance and Child Support in New Hampshire: 2026 Complete Guide

New Hampshire courts require both parents to contribute to their children's health insurance coverage as part of every child support order. Under RSA 458-C:3, the presumptive medical support obligation equals 4% of each parent's gross income, and courts must include specific health care coverage provisions in all support orders. This comprehensive guide explains how health insurance child support New Hampshire families must navigate works under current law, from calculating costs to enforcing coverage requirements.

How New Hampshire Calculates Medical Support Obligations

New Hampshire law establishes a medical support obligation equal to 4% of each parent's individual gross income as the presumptive standard for health insurance contributions under RSA 458-C:3, V. This percentage applies regardless of which parent actually provides coverage, creating a ceiling for reasonable medical support costs. When private health insurance premiums exceed the combined 4% obligations of both parents, the court may allocate costs proportionally or find the coverage unreasonable.

The state uses the Income Shares model codified in RSA 458-C, which calculates base child support from both parents' combined adjusted gross income. Medical support obligations layer on top of this base calculation. For example, if Parent A earns $60,000 annually and Parent B earns $40,000 annually, the combined income totals $100,000. Parent A's presumptive medical support cap equals $2,400 annually (4% of $60,000), while Parent B's cap equals $1,600 annually (4% of $40,000). Together, they can contribute up to $4,000 annually toward children's health coverage before costs become unreasonable under guidelines.

Additional costs for health insurance, childcare, and extraordinary medical expenses get allocated between parents in the same proportions as their share of combined income. Using the example above, Parent A (60% of income) would bear 60% of medical costs beyond base support, while Parent B (40% of income) would bear 40%.

Who Must Provide Health Insurance for Children

Under RSA 461-A:14, every child support order must include the court's determination and findings relative to health care coverage for dependent children. The court first determines whether private health insurance is accessible and available to either parent at a cost at or below the reasonable medical support obligation amount. If such coverage exists, the court orders the parent or parents to provide it.

Accessible health insurance means primary care services are located within 50 miles or one hour from the child's primary residence. This geographic requirement ensures children can actually use the coverage without unreasonable travel burdens. Courts reject insurance plans requiring families to travel across state lines for routine pediatric care.

The cost of providing private health insurance equals the actual cost of adding the child to existing coverage, or the difference between individual and family coverage. This calculation prevents charging one parent the full family premium when other dependents benefit from that same coverage. If a parent has employer-sponsored individual coverage costing $300 monthly and family coverage costing $500 monthly, the child's coverage cost equals $200 monthly—the difference between plans.

When both parents have private health insurance covering the child, the insurance of the parent obligated by court order to provide health care coverage becomes the primary coverage for the child. This prevents disputes about which policy pays first for medical claims.

Medical Support Order Requirements in New Hampshire

New Hampshire law now requires any child support order where support is payable through the Division of Child Support Services (DCSS) to include a medical support provision addressing reasonable cost. Orders entered before this requirement that lack medical support provisions must be updated when modifications occur. The medical support provision must specify which parent provides coverage, the cost allocation between parents, and procedures for handling uninsured medical expenses.

RSA 461-A:14 defines health care coverage broadly to include fee for service plans, health maintenance organizations (HMOs), preferred provider organizations (PPOs), and other types of private health insurance. Public health care coverage like Medicaid or CHIP also satisfies the medical support requirement when private coverage is unavailable or unaffordable.

Courts must make written findings about the availability and accessibility of coverage before ordering either parent to provide insurance. If neither parent has access to coverage meeting the reasonable cost standard, the court may order cash medical support instead. Cash medical support creates a monetary obligation toward health care costs rather than requiring a parent to maintain specific insurance coverage.

Extraordinary Medical Expenses Beyond Insurance

New Hampshire has specialized guidelines for sharing a child's extraordinary medical care costs separate from and in addition to basic child support payments. Extraordinary medical costs typically include expenses generated by serious illness, hospital visits, or costly procedures such as orthodontic braces. These expenses exceed routine copays and deductibles covered by insurance.

Under RSA 458-C:5, courts may deviate from guideline support amounts when application would be unjust or inappropriate. Factors justifying deviation include extraordinary medical, dental, or educational expenses. Parents with children requiring ongoing specialized care may negotiate specific allocations for these predictable but substantial costs.

The child support guidelines worksheet addresses extraordinary medical expenses by allocating them proportionally between parents based on their income percentages. If one parent earns 70% of combined income, that parent typically bears 70% of uninsured orthodontia, therapy, or other medical costs exceeding normal insurance coverage. Parents should document these agreements clearly in their parenting plan or stipulation.

Cash Medical Support as Alternative Coverage

When ordered in lieu of private health care coverage, an obligation for cash medical support suspends and does not accrue during such time as the obligated parent provides private health care coverage in accordance with court orders. This provision allows flexibility when coverage circumstances change. A parent initially ordered to pay cash medical support can switch to providing actual insurance coverage without penalty.

Courts may order either or both parents to pay a medical support obligation—either to provide health care coverage or as cash medical support—in excess of the reasonable medical support obligation amount in circumstances the court deems appropriate. This authority allows judges to ensure children receive adequate medical coverage even when costs exceed presumptive guidelines.

Cash medical support typically routes through the Division of Child Support Services for tracking and enforcement alongside regular child support payments. Parents receiving cash medical support use these funds to purchase marketplace coverage, maintain COBRA continuation coverage, or cover the child's portion of employer-sponsored premiums.

COBRA and Continuation Coverage After Divorce

New Hampshire offers state continuation coverage that works like federal COBRA but extends to employees of all size employers. Under federal COBRA regulations and state continuation rules, divorced or legally separated spouses of covered employees may continue health coverage for up to 36 months following divorce. New Hampshire State Continuation allows dependents to continue on group health insurance at the employer's full price plus a 2% administrative fee.

A court decree of legal separation or divorce is required to trigger COBRA eligibility—simply filing paperwork or starting the divorce process does not qualify. The covered employee's spouse must notify the plan administrator of the divorce within 60 days of the final divorce decree. The plan administrator then sends an Election Notice within 44 days after the qualifying event.

Generally, divorce does not automatically terminate a child's health insurance coverage under a parent's plan. Children can remain on one parent's employer-sponsored plan regardless of divorce, and the decree should specify which parent maintains coverage and how costs divide between parents. Children covered as dependents on a parent's employer plan remain eligible until age 26 under the Affordable Care Act, regardless of student status, marital status, or financial independence.

Modifying Health Insurance Provisions in Support Orders

New Hampshire law provides two pathways for modifying child support orders, including medical support provisions, under RSA 458-C:7. Parents can request a modification by showing a substantial change in circumstances at any time. Alternatively, parents may request a review every 3 years after the last support order without demonstrating any specific change.

Common reasons for seeking health insurance child support New Hampshire modifications include loss of employer-sponsored coverage, substantial increase or decrease in income affecting the 4% threshold, change in the parenting plan affecting which parent should provide coverage, or significant changes in the child's medical needs increasing extraordinary expenses.

If your current order does not include a medical support provision addressing reasonable cost, any agreement or petition you file with the court must include such a provision. This requirement ensures all modifications bring orders into compliance with current law. The modification process requires a formal filing with the Family Division court where your original order was entered.

The filing fee for modification petitions ranges from $135 to $225 in New Hampshire. Courts may grant temporary modifications if an emergency or short-term issue affects a parent's ability to maintain coverage, such as sudden job loss eliminating employer-sponsored insurance. Parents must provide updated financial information during any review, and courts recalculate support using current income figures.

Enforcing Health Insurance Requirements

New Hampshire courts have multiple enforcement mechanisms when a parent fails to maintain required health insurance coverage for children. The Division of Child Support Services can initiate contempt proceedings against parents who violate court-ordered insurance obligations. Courts may impose sanctions including fines, wage garnishment adjustments, or even incarceration for willful violations.

Some parents attempt to avoid child support duties by quitting jobs or taking low-paying employment that eliminates access to affordable coverage. New Hampshire judges have authority to impute (assign) additional income to a parent who is voluntarily underemployed or unemployed without legitimate reason. This imputed income then factors into recalculated support obligations, including medical support caps.

When a parent fails to maintain insurance as ordered and the child incurs medical expenses, the violating parent may be held responsible for the full cost of those expenses rather than just their proportional share. Courts treat insurance violations seriously because gaps in coverage can result in catastrophic financial consequences for families and may delay necessary medical care for children.

Calculating Health Insurance Costs on the Guidelines Worksheet

New Hampshire provides Form DCSS s650 (Child Support Guidelines Worksheet) and Form DCSS s651 (Guideline Calculation Table) for calculating support including medical support obligations. For the child support calculation, parents enter the actual amount paid for adding the children covered by the order to existing health insurance coverage, or the difference between individual and family coverage.

The worksheet allocates health insurance costs proportionally based on each parent's percentage of combined income. If Parent A provides coverage and pays $200 monthly for the children's portion of premiums, this amount enters the worksheet and credits against Parent A's overall support obligation. Parent B's base support amount adjusts to account for Parent A's insurance contribution.

For cases involving allowable child care expenses or medical support obligation expenses incurred by the obligee (receiving parent), the methodology remains consistent. The obligee's allowable child care expenses or medical support obligation expenses deduct from the adjusted gross income of the obligee when determining each parent's share of the child support obligation. This ensures parents who bear actual coverage costs receive appropriate credits.

When Neither Parent Has Affordable Coverage

When neither parent has access to private health insurance meeting the reasonable cost standard (at or below 4% of gross income), courts explore alternative coverage options. Public health care programs including Medicaid and the Children's Health Insurance Program (CHIP) offer free or low-cost coverage for children in income-qualifying families. Enrollment in these programs can occur at any time through HealthCare.gov or the Covering NH website.

Marketplace insurance purchased through the federal exchange may qualify when employer-sponsored coverage is unavailable. Premium tax credits reduce costs for families between 100% and 400% of the federal poverty level. Children may qualify for CHIP at higher income levels than their parents qualify for Medicaid, often up to 300% of the federal poverty level.

Courts may order cash medical support when no accessible private coverage exists at reasonable cost. This cash obligation supplements any public coverage by addressing copays, deductibles, and services not covered by Medicaid or CHIP. Parents should update the court when coverage circumstances change, as obtaining affordable private coverage may trigger modification of cash medical support orders.

Self-Support Reserve and Medical Support

New Hampshire's child support guidelines incorporate a self-support reserve equal to 130% of the federal poverty guideline for a single person living alone, as determined annually by the U.S. Department of Health and Human Services. For 2026, this self-support reserve approximately equals $1,600 monthly. This reserve protects obligors from support orders that would reduce their income below poverty levels.

When applying the self-support reserve, courts may adjust medical support obligations along with base child support. A parent earning just above the self-support reserve cannot sustain the full 4% medical support obligation without falling into poverty. Courts balance children's coverage needs against obligors' minimum survival requirements.

The self-support reserve calculation occurs after determining gross income but before calculating final obligations. Parents with very low incomes may receive reduced or waived medical support obligations while still bearing responsibility for base child support at minimum amounts set by guidelines.

Frequently Asked Questions

What percentage of income goes toward children's health insurance in New Hampshire?

New Hampshire law presumes a reasonable medical support obligation of 4% of each parent's individual gross income under RSA 458-C:3, V. This 4% cap applies to the cost of adding children to health insurance coverage. When actual premium costs fall below this threshold, the parent pays actual costs; when costs exceed 4%, courts may find coverage unreasonable.

Can I be required to keep my child on my health insurance after divorce?

Yes. Under RSA 461-A:14, courts must determine health care coverage arrangements in every child support order and can order either or both parents to provide insurance if accessible coverage is available at or below the 4% reasonable cost threshold. If your employer coverage costs less than 4% of gross income to add children, courts typically order you to maintain it.

How does health insurance affect my child support calculation in New Hampshire?

Health insurance premiums paid for children credit against the paying parent's overall support obligation on the Child Support Guidelines Worksheet. If you pay $250 monthly to add your children to your employer plan, this amount reduces your base support obligation dollar-for-dollar. Extraordinary medical expenses allocate proportionally based on income percentages.

What happens if my employer plan doesn't cover doctors near my child?

New Hampshire defines accessible health insurance as coverage with primary care services located within 50 miles or one hour from the child's primary residence. If your employer plan requires traveling further for routine pediatric care, courts may find the coverage inaccessible and order the other parent to provide coverage or order cash medical support.

How often can I request changes to health insurance provisions in my support order?

New Hampshire allows modification requests every 3 years after the last support order without requiring any specific change in circumstances. For substantial changes like losing employer coverage or significant income changes, you can request modification at any time. The filing fee for modification petitions ranges from $135 to $225.

What if neither parent can afford health insurance for our children?

When private coverage exceeds the reasonable cost threshold (combined 4% of both parents' gross incomes), courts explore alternatives including Medicaid, CHIP, or cash medical support. Children often qualify for CHIP at income levels up to 300% of the federal poverty level. Courts may order cash medical support to supplement public coverage.

Does the other parent have to help pay for orthodontia and other uninsured expenses?

Yes. New Hampshire guidelines allocate extraordinary medical expenses—including orthodontia, therapy, and hospital costs beyond insurance coverage—between parents proportionally based on their income percentages. If you earn 60% of combined parental income, you typically bear 60% of uninsured medical costs.

How long does children's health coverage continue under my divorce decree?

Children remain eligible for coverage under either parent's plan until age 26 under the Affordable Care Act regardless of divorce, student status, or financial independence. Your divorce decree specifies which parent maintains coverage and how costs divide, but these obligations continue until the child ages out of dependent eligibility.

What is cash medical support in New Hampshire?

Cash medical support is a monetary payment toward health care costs ordered when private insurance coverage is unavailable, inaccessible, or exceeds the reasonable cost threshold. This cash obligation routes through the Division of Child Support Services and suspends automatically when the paying parent begins providing actual insurance coverage.

Can I use COBRA coverage for my children after divorce?

COBRA typically covers you as the former spouse for up to 36 months following divorce, but children generally remain eligible for coverage under the employed parent's plan without needing COBRA. New Hampshire State Continuation extends COBRA-like coverage to employees of all size employers at full premium plus 2% administrative fee.
