Child Support in Connecticut
Connecticut calculates child support using the income shares model in the Connecticut Child Support and Arrearage Guidelines. The guidelines combine the mother's and father's income with the number of children to set a presumptive support amount. Separate formulas then split medical insurance costs and work-related child care expenses between the parents. Connecticut Superior Court judges and family support magistrates both hear child support matters. Both must follow the guidelines unless they state a specific reason for departing from them. The Department of Social Services' child support program helps parents apply for services, calculate an amount, and enforce an order already in place.

The income shares guidelines
Connecticut's guidelines start with the combined net income of both parents and the number of children in the case. That combination is used to look up a basic support obligation on a schedule. The guidelines then split that obligation between the parents based on their share of the combined income. They separately allocate the cost of the child's health insurance and work-related child care. A commission reviews and updates the guidelines periodically, and the current version is published by the Connecticut Judicial Branch.
Applying for services through DSS
The Connecticut Department of Social Services runs the state's child support program. It is the point of contact for a parent who wants help establishing, collecting, or enforcing a support order. A parent applies for services through the department's application process. The program can also help establish paternity when that hasn't already been done.
Who hears a Connecticut child support case
Child support cases in Connecticut are decided in Superior Court. The state also uses family support magistrates, alongside judges, to hear these cases, particularly IV-D cases involving the state child support program. Both judges and family support magistrates must apply the income shares guidelines unless they make a specific finding on the record to justify a different amount.
Modifying an existing order
A Connecticut child support order can be modified when a parent shows a substantial change in circumstances since the order was entered. It can also be modified when applying the current guidelines to the parents' present income would produce a significantly different result than the existing order. The specific numeric threshold and any periodic review timeline appear in the Child Support and Arrearage Guidelines and in state statute. Confirm the current standard before filing a modification motion.
Enforcement tools
Connecticut law allows wages to be withheld to satisfy a child support order. Income withholding is typically part of how a support order is enforced going forward. The Department of Social Services' child support program can also pursue state and federal tax refund interception and license suspension against a parent who falls behind. A parent can also be held in contempt of court for failing to pay a court-ordered amount.
