New London County, Connecticut Child
Support Estimator

Connecticut child support is calculated under statewide Income Shares guidelines, but the filing, review, and enforcement process is local. Parents in New London County use the same statewide formula as the rest of Connecticut, then work through the county family court or child support agency process for orders, modifications, and enforcement.

New London County ranks 4th by population among 8 Connecticut counties. That matters for scheduling, clerk procedures, local forms, and how quickly a support order or modification moves through the court calendar.

Use this page to estimate the guideline amount first, then verify filing steps with the local court before submitting paperwork.

New London County's larger population can mean higher case volume, more specialized family-law practitioners, and more formal local procedures for child support hearings.

The core inputs are each parent's income, the number of children, health insurance premiums, work-related child care, existing support obligations, and parenting time. Connecticut's calculator model is Income Shares.

Governing authority: Conn. Gen.

Stat. § 46b-215a.

County location does not usually change the statewide formula, but it does determine where parents file, which clerk reviews paperwork, and which local judge or hearing officer applies the guidelines. Income Shares model under Conn.

Gen. Stat. § 46b-215a using both parents' combined net weekly income and the Connecticut Child Support and Arrearage Guidelines schedule (revised 2015, updated 2022).

The schedule covers combined net weekly income up to $4,000/week ($208,000/year); above that, the court exercises discretion. Net weekly income deducts federal and state income taxes, FICA, Medicare, and mandatory union dues.

A parenting-time credit applies when the non-custodial parent exercises more than the minimum access schedule — typically 15%+ of overnights. Child care costs and unreimbursed medical expenses exceeding $250/year per child are allocated proportionally.

Low-income families with net weekly income below $75/person may qualify for a minimum order. Administered by the Connecticut Support Enforcement Services (SES) division of the Judicial Branch.

Statute: Conn. Gen.

Stat. §§ 46b-215a through 46b-215b.

Run the calculator with monthly or weekly income figures that match the official Connecticut worksheet. If a parent is self-employed, unemployed, or paid irregularly, gather tax returns, pay stubs, and proof of benefits before relying on the estimate.

Parenting time can affect child support because many states adjust the payment when the paying parent has substantial overnights. Enter the actual schedule, not the schedule you expect to negotiate later.

Parents in New London County should keep a written parenting-time calendar, school schedule, holiday rotation, and transportation plan. Those documents help the court compare the calculator estimate with the real custody arrangement.

If custody is still disputed, treat the estimate as a planning number. A final Connecticut child support order can change once the court sets income findings, parenting time, insurance credits, and child care allocations.

A child support estimate is not a court order. To change an existing order, a parent usually must file a modification request and show a qualifying change in income, custody, health insurance, child care costs, or another guideline factor.

For enforcement, Connecticut may use income withholding, payment records, tax refund interception, license actions, or contempt proceedings depending on the facts and the agency or court handling the case.

Before filing in New London County, compare your calculator result with the current order and collect proof for each input. Courts generally need documents, not estimates alone, before changing a support obligation.

Child support often intersects with custody, alimony, property division, and divorce costs. Use the Connecticut Custody Time Calculator to model overnights, then compare support with the Connecticut Alimony Calculator and Connecticut Divorce Cost Estimator.
