Connecticut becomes the first U.S. state to publish a three-parent child support worksheet when its revised Child Support and Arrearage Guidelines under Conn. Gen. Stat. § 46b-215a take effect August 1, 2026. The overhaul expands the income schedule to $312,000 per year, adds a first-in-the-nation CCSG-1A form with a third income column, and creates dollar-for-dollar Social Security Disability arrears credits.

The changes, reported by Family Law Software, represent the most significant overhaul of Connecticut's child support framework in years. The guidelines are recalibrated every four years under state law, but the 2026 revision breaks new ground nationally by formally accommodating families with three legal parents.
Why This Matters Legally
This reform changes how Connecticut courts calculate child support for both ordinary and non-traditional families, and it makes Connecticut the national testing ground for three-parent support math. Before August 1, 2026, no state guideline worksheet had a formal third income column; multi-parent obligations were handled through ad hoc court orders. The new CCSG-1A worksheet supplies a standardized method, reducing judicial guesswork and improving predictability.
The practical significance is large. When three adults are legally recognized as parents under the Connecticut Parentage Act, each may carry a support obligation, and the combined income must be apportioned among them. A formal worksheet means Connecticut families no longer depend on individual judges improvising a formula. That standardization is exactly what child support guidelines exist to provide, and Connecticut is now the first state to extend it beyond the traditional two-parent model.
The income schedule expansion also matters. By raising the top of the schedule to $312,000 per year, Connecticut captures more high-earning households within the presumptive guideline calculation rather than leaving them to discretionary deviation.

How Connecticut Law Handles This
Connecticut calculates child support under the income shares model codified at Conn. Gen. Stat. § 46b-215a, which directs the Commission for Child Support Guidelines to establish and periodically revise the presumptive amounts. Under Conn. Gen. Stat. § 46b-215b, those guidelines are presumptively correct in any proceeding, and a court must make a specific finding on the record to deviate from them.
The Connecticut Parentage Act, effective January 1, 2022, is the statutory foundation that makes a three-parent worksheet possible. The Act allows a child to have more than two legal parents in defined circumstances, including certain assisted-reproduction and de facto parentage situations. Because the Act recognizes tri-parentage as a legal reality, the child support guidelines must now supply a matching calculation tool — and the CCSG-1A worksheet fills that gap.
Three additional refinements arrive with the 2026 guidelines. First, the revision adds dollar-for-dollar credits against child support arrears for Social Security Disability (SSD) dependency benefits paid on the obligor's account, aligning arrears treatment with how current support already credits derivative benefits. Second, the guidelines clarify how Connecticut Paid Family and Medical Leave (PFML) benefits are treated as income for support purposes. Third, the schedule recalibration updates the underlying economic data used to set presumptive amounts.

Practical Takeaways
-
Confirm your effective date. Any support order calculated on or after August 1, 2026, should use the revised guidelines and, where applicable, the CCSG-1A worksheet. Orders entered before that date remain governed by the prior schedule until modified.
-
Recheck high-income cases. If combined parental income approaches or exceeds the old schedule ceiling, the expansion to $312,000 per year may change your presumptive obligation. High earners previously handled by deviation may now fall inside the guideline calculation.
-
Three-parent families should request the CCSG-1A worksheet. If parentage has been established for three legal parents under the Connecticut Parentage Act, ask the court to apply the new three-column worksheet rather than a two-parent form. Understanding your parenting plan obligations is essential when three adults share responsibility.
-
SSD recipients should document dependency benefits. If your child receives Social Security Disability dependency benefits on your record, the new dollar-for-dollar arrears credit could reduce what you owe on back support. Bring benefit statements to any modification hearing.
-
Disclose PFML income accurately. Because the 2026 guidelines clarify Paid Family and Medical Leave treatment, report PFML benefits when completing your financial affidavit so your support figure reflects current rules.
-
Consider a modification review. A change in the guidelines can, in some cases, support a motion to modify an existing order. Consult counsel about whether the recalibration produces a substantial change in circumstances for your situation. A personalized divorce roadmap can help you organize next steps before you file.
If you are facing a Connecticut support determination — especially a high-income case or a three-parent family — the August 1, 2026 changes may directly affect your numbers.
