How Connecticut child support is calculated

Connecticut's child support is calculated using the Income Shares Model. First, each parent's net weekly income is determined by subtracting allowable deductions (taxes, insurance, mandatory dues) from their gross income. These net incomes are combined to find the 'combined net weekly income.' This combined income is then applied to the 'Connecticut Schedule of Basic Child Support Obligation' table, cross-referenced with the number of children, to establish a basic child support amount. Each parent's share of this basic obligation is proportional to their contribution to the combined net income. Finally, pro-rata shares of medical and childcare expenses are added to each parent's obligation. Courts can deviate from these guidelines if the calculated amount is deemed unjust or inappropriate.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Parenting time shifts

If the custody schedule changes significantly, support can be recalculated under Connecticut guidelines.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.

Common questions

What people ask about child support

How long does a divorce take in Connecticut?

In Connecticut, there is a mandatory 90-day waiting period after the return date. Most uncontested cases resolve in 3-6 months, while contested divorces can take much longer, sometimes over a year.

Do I need a lawyer to get divorced in Connecticut?

While not legally required, it is highly recommended to consult with a lawyer for a divorce in Connecticut, especially in contested cases or those involving complex assets or child custody. Self-representation is possible, but navigating the legal process can be challenging.

Is Connecticut a no-fault divorce state?

Yes, Connecticut is primarily a no-fault divorce state, meaning a divorce can be granted on the grounds of "irretrievable breakdown of the marriage." However, fault-based grounds also exist under Conn. Gen. Stat. § 46b-40(c)(1).

How is property divided in Connecticut divorce?

Connecticut follows the principle of equitable distribution, as outlined in Conn. Gen. Stat. § 46b-81. This means marital property is divided fairly, but not necessarily equally (50/50), based on various factors considered by the court.

Is mediation required in Connecticut divorce cases?

Mediation is not statutorily required in Connecticut divorce cases. However, judges may recommend it, and it is a voluntary process that can help couples resolve disagreements amicably and avoid lengthy court battles.
