Residency requirement:
Under Conn. Gen. Stat. §46b-44, at least one spouse must have been a Connecticut resident for a minimum of 12 months before the divorce can be finalized. You can file the divorce complaint before completing the 12-month period, but the court will not enter a final decree until the residency requirement is satisfied. There is no separate county-level residency requirement.
Filing fee:
$350–$360
Waiting period:
Connecticut uses the 'Income Shares Model' to calculate child support under the Connecticut Child Support and Arrearage Guidelines (Conn. Agencies Regs. §46b-215a-2c). Both parents' net weekly incomes are combined, and a basic support obligation is determined from a schedule based on the combined income and number of children, then allocated proportionally between the parents. The court may deviate from the guidelines in certain circumstances, such as shared physical custody or extraordinary expenses.

Connecticut law mandates that every child support order include provisions for health insurance coverage under Connecticut General Statutes § 46b-84. Parents must provide medical coverage for their children when available at reasonable cost, defined as no more than 5% of net income for low-income obligors or 7.5% for all other parents. Health insurance premiums, unreimbursed medical expenses, and work-related childcare costs are calculated separately from basic support and allocated proportionally based on each parent's share of combined income.

How Connecticut Courts Handle Health Insurance in Child Support Orders

Connecticut courts require every child support order to address health insurance coverage for minor children under C.G.S. § 46b-84. The court will order whichever parent has access to employer-sponsored coverage at reasonable cost to maintain that coverage for the children. If neither parent has affordable employer coverage, the court may order enrollment in Connecticut's HUSKY Plan (the state's Medicaid and CHIP program) or require cash medical support payments. The parent who does not carry the insurance reimburses the providing parent for the children's share of the premium, calculated proportionally based on each parent's percentage of combined net income.

Connecticut defines reasonable cost using a two-tier threshold system. For parents who qualify as low-income obligors under the child support guidelines, health insurance costs cannot exceed 5% of that parent's net income. For parents who do not qualify as low-income, the threshold rises to 7.5% of net income. If employer-sponsored coverage exceeds these thresholds, the court may excuse the parent from providing private insurance and instead order HUSKY enrollment or cash medical support.

The Connecticut Child Support Guidelines and Medical Support

Connecticut uses an income shares model for calculating child support under Conn. Agencies Regs. § 46b-215a-2c. The guideline child support amount covers basic needs including food, clothing, and shelter. Health insurance premiums for children, work-related childcare expenses, and unreimbursed medical costs are not included in this basic amount. Instead, these expenses are calculated separately as add-on costs and allocated between parents based on their proportional income shares.

How Add-On Expenses Are Calculated

After determining the basic child support obligation, parents complete the Child Support Guidelines Worksheet (Form JD-FM-220) to calculate health insurance allocations. The worksheet requires each parent's net weekly income to determine their percentage of combined income. For example, if Parent A earns $800 weekly (60% of combined income) and Parent B earns $533 weekly (40%), Parent A pays 60% of children's health insurance premiums and Parent B pays 40%.

Types of Medical Support Orders Available

Connecticut courts have several options when crafting medical support orders under C.G.S. § 46b-84. The court may order employer-sponsored health insurance, HUSKY enrollment, cash medical support, or a combination of these approaches. The health care coverage requirement may be satisfied through any of the following methods, and courts often order multiple provisions to ensure comprehensive coverage.

Employer-Sponsored Health Insurance

The most common arrangement requires the parent with affordable employer coverage to add the children to their plan. The insuring parent pays the full premium directly to their employer, then the non-insuring parent reimburses their proportional share. If monthly premiums for children's coverage cost $400 and one parent earns 55% of combined income, that parent owes $220 monthly toward the premium while the other parent owes $180.

HUSKY Plan Enrollment

When neither parent has access to affordable employer coverage, the court may order application for HUSKY B (Connecticut's Children's Health Insurance Program) or HUSKY A (Medicaid). HUSKY provides comprehensive coverage for children in families meeting income guidelines. If HUSKY coverage is ordered, the court may also require cash medical support to cover any cost-sharing requirements under the plan.

Cash Medical Support

Cash medical support involves a monthly payment toward health insurance costs rather than maintaining a specific insurance policy. Courts typically order cash medical support when employer coverage exceeds the reasonable cost threshold (5% or 7.5% of net income) or when the child qualifies for public insurance. The cash amount covers premiums, cost-sharing, or contribution toward the other parent's coverage expenses.

Unreimbursed Medical Expenses: Allocation and Thresholds

Unreimbursed medical expenses including co-pays, deductibles, prescriptions, orthodontia, eyeglasses, dental work, and mental health treatment are shared proportionally between parents based on income percentages. Connecticut child support orders allocate these expenses separately from the basic support amount. The court determines each parent's percentage responsibility based on their share of combined net income.

Common Threshold Provisions

Many Connecticut custody agreements establish a threshold amount, commonly $250 per year, before cost-sharing begins. Under this arrangement, the custodial parent covers routine expenses up to the threshold, and both parents share costs proportionally above that amount. This approach reduces the administrative burden of tracking and reimbursing small medical expenses throughout the year.

Documentation Requirements

Parents must submit unreimbursed medical expenses to the other parent within 30 days of incurring the cost, along with documentation showing the expense and amount paid by insurance. The reimbursing parent typically has 30 days to pay their share. Failure to submit expenses within the timeframe may result in forfeiture of the right to reimbursement, depending on the specific terms of the court order.

The National Medical Support Notice Process

Connecticut enforces employer-sponsored health insurance orders through the National Medical Support Notice (NMSN) under C.G.S. § 46b-88. When a court orders a parent to maintain employer-based health coverage, the state child support agency sends an NMSN directly to the employer. This legal document has the same force as a court order and requires the employer to enroll the child in available health coverage.

Employer Responsibilities Under NMSN

Employers receiving an NMSN must respond within 20 business days by either transferring the notice to the group health plan administrator or returning the notice with an explanation of why coverage is unavailable. The employer must withhold the employee's share of premium costs from wages and send payments directly to the insurance plan. Employers cannot deny enrollment because the child was born out of wedlock, does not live with the employee, or is not claimed as a tax dependent.

Plan Administrator Duties

Health plan administrators must treat the NMSN as a qualified medical child support order and enroll the child within 40 business days. Enrollment cannot be denied due to open enrollment restrictions, and if the parent employee is not enrolled, both parent and child must be enrolled simultaneously. The administrator must notify the issuing agency of coverage availability and provide coverage descriptions to the custodial parent.

Modifying Health Insurance Provisions

Health insurance provisions in Connecticut child support orders may be modified when circumstances substantially change. Common grounds for modification include job loss eliminating employer coverage, significant income changes affecting the reasonable cost calculation, children aging out of coverage at 26, or one parent obtaining more affordable coverage options. Either parent may file a motion to modify with the court that issued the original order.

When Insurance Becomes Unavailable

If the parent providing insurance loses coverage due to job loss or employer plan changes, they must immediately notify the other parent and the court. The court will then determine whether the other parent should provide coverage, whether HUSKY enrollment is appropriate, or whether cash medical support should replace the insurance requirement. Failure to maintain ordered coverage can result in contempt proceedings.

Cost Increase Modifications

When insurance premiums increase substantially, either parent may seek modification if the new cost exceeds the reasonable cost threshold (5% or 7.5% of net income). The court will recalculate whether employer coverage remains reasonable or whether alternative arrangements better serve the children's interests.

Children with Disabilities: Extended Coverage Requirements

Connecticut provides extended child support and medical coverage requirements for children with intellectual, mental, or physical disabilities. For child support orders entered on or after October 1, 2023, C.G.S. § 46b-84(c) allows courts to order support for a qualifying child until age 26 rather than the standard age 18 or 19 cutoff. This extended support includes medical insurance obligations.

The court may order appropriate support for any child with an intellectual disability (as defined in section 1-1g) or mental or physical disability (as defined in section 46a-51) who resides with a parent and is principally dependent upon that parent for maintenance. This provision ensures continued health coverage for vulnerable young adults who cannot independently obtain insurance or employment.

Health Insurance During the Divorce Process

During divorce proceedings, both parents remain obligated to maintain existing health insurance coverage for minor children. Connecticut courts issue automatic orders upon filing that prohibit either party from removing children from existing health insurance policies. These orders remain in effect until the final divorce decree establishes permanent insurance arrangements.

Temporary Support Orders

Either parent may request temporary support orders addressing health insurance during the pendency of the divorce. The court can order one parent to maintain existing coverage and require the other to contribute toward premium costs pending final resolution. Temporary orders typically mirror the anticipated final arrangement based on preliminary income information.

COBRA Considerations

If the custodial parent and children were covered under the non-custodial parent's employer plan during the marriage, divorce triggers a qualifying event for COBRA continuation coverage. The custodial parent may elect COBRA coverage for themselves for up to 36 months post-divorce. Children may also receive COBRA coverage, though courts typically order the non-custodial parent to maintain children on their employer plan rather than using more expensive COBRA coverage.

Enforcement of Medical Support Orders

Connecticut provides multiple enforcement mechanisms when a parent fails to maintain ordered health insurance coverage or pay their share of medical expenses. The other parent may file a motion for contempt, seek wage withholding through Support Enforcement Services, or request modification if the ordered arrangement has become unworkable.

Contempt Proceedings

When a parent willfully fails to maintain health insurance as ordered, the other parent may file a motion for contempt of court. If the court finds willful violation, penalties may include fines, payment of the other parent's attorney fees, makeup payments for uncovered medical expenses, and in severe cases, incarceration. The burden shifts to the non-compliant parent to prove inability rather than unwillingness to comply.

Wage Withholding for Medical Costs

Connecticut Support Enforcement Services can implement wage withholding for health insurance premiums and unreimbursed medical expense reimbursements. The employer deducts these amounts from the obligor's paycheck and remits payment to the other parent or directly to insurance providers. This automatic process reduces non-compliance and eliminates the need for repeated enforcement actions.

Filing Fees and Court Costs

The Connecticut divorce filing fee is $350-$360 as of March 2026, with an additional $50 for service of process bringing minimum court costs to approximately $400. Parents must also complete mandatory parenting education programs costing approximately $125-$150 per person. Fee waivers are available through Form JD-FM-75 for parents whose income falls below 125% of the federal poverty level, those receiving state assistance (SNAP, TFA/TANF, Medicaid), or those who can demonstrate substantial hardship.

Connecticut Residency Requirements

Connecticut requires at least one spouse to have resided in the state for 12 months before a divorce decree can be granted under C.G.S. § 46b-44. You may file for divorce before completing the 12-month period, but the court will not finalize the divorce until the residency requirement is satisfied. Military personnel who were Connecticut residents at enlistment are deemed to have continuously resided in Connecticut throughout their service.

Frequently Asked Questions

Can my ex-spouse be required to keep our children on their employer health insurance after divorce?

Yes, Connecticut courts routinely order the parent with employer-sponsored coverage to maintain children on their plan under C.G.S. § 46b-84. The coverage must be available at reasonable cost, defined as no more than 5% of net income for low-income parents or 7.5% for others. If your ex-spouse refuses to comply, the court can enforce the order through contempt proceedings or wage withholding via the National Medical Support Notice process.

How are children's health insurance premiums divided between divorced parents in Connecticut?

Health insurance premiums are allocated proportionally based on each parent's percentage of combined net income. If you earn 60% of the combined income, you pay 60% of the children's health insurance premium costs. The parent who carries the insurance typically receives reimbursement from the other parent monthly, calculated using the Child Support Guidelines Worksheet.

What happens if neither parent has access to affordable employer health insurance?

When employer coverage exceeds the reasonable cost threshold or is unavailable, Connecticut courts may order enrollment in HUSKY (Connecticut's Medicaid and CHIP programs) or require cash medical support payments. HUSKY B provides coverage for uninsured children in higher-income households, while HUSKY A serves lower-income families. The court determines the most appropriate coverage arrangement based on family income and available options.

How are unreimbursed medical expenses handled in Connecticut child support orders?

Unreimbursed medical expenses including co-pays, deductibles, prescriptions, orthodontia, and therapy are divided proportionally between parents based on income percentages. Many custody agreements establish a $250 annual threshold before cost-sharing begins. Parents must submit documented expenses to each other within 30 days, and reimbursement is typically due within 30 days of submission.

What is the National Medical Support Notice and how does it work?

The National Medical Support Notice (NMSN) is a legal enforcement tool under C.G.S. § 46b-88 that Connecticut uses to enforce health insurance orders. The state child support agency sends the NMSN directly to the obligated parent's employer, requiring enrollment of the children within 40 business days. Employers must withhold premium costs from wages and remit payment directly to the insurance plan.

Can health insurance requirements be modified after the divorce is final?

Yes, either parent may request modification when circumstances substantially change. Common grounds include job loss eliminating employer coverage, significant income changes, premium increases exceeding the reasonable cost threshold, or access to more affordable coverage options. File a motion to modify with the court that issued the original order, demonstrating the substantial change in circumstances.

Does child support in Connecticut cover medical expenses beyond health insurance?

The basic child support amount covers only food, clothing, and shelter. Health insurance premiums, work-related childcare, and unreimbursed medical expenses are calculated separately as add-on costs. These expenses are allocated proportionally based on income percentages and added to the basic support obligation, creating a total child support award that addresses all categories of expenses.

How long must parents provide health insurance for children in Connecticut?

Parents must provide health insurance until the child turns 18, or 19 if the child is an unmarried full-time high school student. For children with intellectual, mental, or physical disabilities, courts may extend medical support obligations until age 26 under orders entered on or after October 1, 2023. Adult children may also remain on a parent's employer plan until age 26 under the Affordable Care Act.

What is the reasonable cost standard for health insurance in Connecticut child support cases?

Connecticut defines reasonable cost using a two-tier system. For parents qualifying as low-income obligors under child support guidelines, insurance costs cannot exceed 5% of net income. For all other parents, the threshold is 7.5% of net income. If employer coverage exceeds these percentages, the court may excuse the parent from private insurance and order alternative arrangements like HUSKY enrollment.

Can I be held in contempt for failing to maintain court-ordered health insurance?

Yes, willful failure to maintain ordered health insurance constitutes contempt of court. Penalties may include fines, payment of the other parent's attorney fees, reimbursement for uncovered medical expenses, and potentially incarceration for severe or repeated violations. Courts expect parents to notify each other and the court immediately if coverage becomes unavailable due to job loss or other circumstances beyond their control.
