Connecticut child support is usually calculated under the statewide Child Support and Arrearage Guidelines. The amount is not a simple percentage of one parent’s paycheck. The court starts with verified financial information from both parents, applies the guideline worksheet, and then considers whether a recognized reason supports a different result.
How Connecticut Child Support Is Calculated
The guideline calculation generally considers both parents’ net income, the number of children covered by the order, and specific child-related expenses. Accurate financial affidavits, pay records, tax returns and documentation of benefits or self-employment income can materially affect the worksheet.
- Wages, salaries, overtime, bonuses and commissions
- Self-employment and business income
- Certain benefits, pensions and other recurring income
- Health-insurance premiums for the children
- Qualifying child-care expenses
- Existing support obligations and permitted adjustments
The current official publication is available from the Connecticut Judicial Branch Child Support Guidelines. Online calculators may be useful for orientation, but they do not replace the official worksheet or a review of the facts that determine which numbers belong on it.
When a Court May Deviate From the Guidelines
A guideline result is presumed to be the appropriate amount, but a court may deviate when applying it would be inequitable or inappropriate under an authorized deviation criterion. Shared parenting, extraordinary travel, unusual medical or educational needs, other dependents, substantial assets and special expenses may require additional analysis. None automatically changes support simply because it exists.
A proposed deviation should identify the guideline amount, the specific criterion relied upon and the facts supporting the requested adjustment. A verbal understanding between parents is not a safe substitute for a court order.
Other Child-Related Financial Orders
A support order may also allocate health coverage, unreimbursed medical expenses, work-related child care and other permitted costs. Educational-support orders for post-secondary education are governed by separate requirements and are not ordinary child support. Parenting schedules and support calculations are related, but changing the schedule does not by itself rewrite an existing support order.
Modifying an Existing Child Support Order
A substantial change in circumstances or a qualifying deviation from the current guidelines may support a motion to modify. Common examples include a meaningful income change, job loss, disability, a change in the child’s residence or needs, or a change in health-insurance or child-care expenses. Under Connecticut General Statutes § 46b-86, the timing and legal standard matter.
A change in circumstances does not automatically change the amount due. Until the court modifies the order, the existing order remains enforceable and unpaid amounts may continue to accrue. Connecticut generally limits retroactive modification, which makes prompt filing and proper service important.
Enforcing Child Support
When support is not paid, available remedies may include income withholding, contempt proceedings and other enforcement tools. The correct response depends on the order, payment history and reason for nonpayment. A parent who cannot comply should seek legal advice promptly rather than simply stop paying, and a parent who is owed support should preserve a clear payment record.
Common Connecticut Child Support Questions
Does equal parenting time eliminate child support?
No. Parenting time is relevant, but equal or shared time does not automatically reduce support to zero. The guideline calculation, each parent’s income and any authorized deviation must still be evaluated.
Can parents agree to a different amount?
Parents may present an agreement, but the court must review child-support terms. The agreement should disclose the guideline amount and explain any deviation.
What if income is irregular or paid through a business?
Bonuses, commissions, cash flow, retained business income and personal expenses paid by a business can require a closer financial review. Tax returns alone may not answer every income question.
Does remarriage automatically change support?
Remarriage alone does not automatically rewrite the order. Any requested modification must be based on the governing law and the relevant financial circumstances.
