Connecticut becomes the first state to codify three-parent child support calculations when its revised guidelines take effect August 1, 2026, per Family Law Software. The overhaul introduces a Parent A/B/C worksheet aligned with the Connecticut Parentage Act, expands the income schedule to $312,000 annually, and adds dollar-for-dollar SSDI arrears credits.

Why this matters legally
Connecticut is the first state in the nation to build a child support worksheet that explicitly calculates obligations for three legal parents. Before this reform, the guidelines assumed a two-parent structure, forcing courts to improvise when the Connecticut Parentage Act recognized a third legal parent. The new CCSG-1A worksheet adds Parent A, Parent B, and Parent C columns, giving judges a standardized formula instead of case-by-case discretion.
This change closes a gap that grew after Connecticut enacted the Connecticut Parentage Act, effective January 1, 2022, which allows a child to have more than two legal parents through de facto parentage, assisted reproduction, and surrogacy arrangements. The 2022 statute created legal parentage rights, but the child support formula had not caught up. The August 1, 2026 guidelines finally reconcile the parentage law with the support math, meaning three-parent families now have a defined, predictable calculation rather than a discretionary one.
How Connecticut law handles this
Connecticut calculates child support under the Income Shares Model, codified in Conn. Gen. Stat. § 46b-215a, which requires the Commission for Child Support Guidelines to review the schedule at least every four years. The 2026 revision expands the presumptive income schedule to $6,000 in combined net weekly income — roughly $312,000 per year — up from the prior ceiling. Above that threshold, courts retain discretion to set support based on the child's needs and the parents' circumstances.
The three-parent worksheet flows from the Connecticut Parentage Act, Conn. Gen. Stat. § 46b-450 et seq., which recognizes de facto parents and intended parents in assisted-reproduction cases. Under the new CCSG-1A form, each legal parent's net weekly income is entered in a separate column, the combined figure is applied to the schedule, and each parent's share is prorated. This mirrors the two-parent income-shares logic but distributes the presumptive obligation across all three parents.
Two further changes affect a broader group of Connecticut parents. First, the arrearage guidelines now provide a dollar-for-dollar credit against past-due support for Social Security Disability Insurance (SSDI) dependent benefits paid to the child on a parent's account. Previously, the treatment of these derivative benefits was inconsistent. Under Conn. Gen. Stat. § 46b-215a, the credit now reduces arrears directly rather than being applied at a court's discretion. Second, the guidelines clarify how Connecticut Paid Family and Medical Leave (PFML) benefits are counted, treating them as gross income subject to the standard deductions when computing net weekly income.
For high-income families, the raised $312,000 ceiling matters because it extends the presumptive schedule further up the income ladder. More cases will now fall within the formula's guaranteed range instead of the discretionary zone, which tends to produce more predictable and consistent awards across similar families.
Practical takeaways
-
Recalculate before August 1, 2026 if your case involves high income. If combined net weekly income approaches or exceeds $6,000 ($312,000/year), the new schedule may change the presumptive number. Run both the old and new figures with your attorney to understand the difference.
-
Multi-parent families should request the CCSG-1A worksheet. If a child has three legal parents recognized under the Connecticut Parentage Act, insist that support be calculated using the new three-parent form rather than an improvised two-parent formula.
-
Review SSDI derivative benefits against your arrears. If your child receives SSDI dependent benefits on your account, the dollar-for-dollar arrears credit could substantially reduce past-due balances. Gather your Social Security benefit statements before any hearing.
-
Document Paid Family and Medical Leave income accurately. Because PFML benefits are now clearly treated as income, disclose them in your financial affidavit to avoid a later modification dispute or a claim of concealment.
-
Consider whether a modification is warranted. A change in the guidelines can, in some circumstances, support a motion to modify. Discuss with a Connecticut family law attorney whether the new formula produces a substantial deviation from your current order — generally 15% or more under Connecticut practice.
