Connecticut Alimony Case Law Examples

R.D. v. G.D. (2026)
Appellate Court of Connecticut, AC 46789

Landmark 2026 ruling: Post-separation increases in a spouse's income are relevant and may be considered by the court when determining alimony. The court held that income at the time of trial, not merely at separation, reflects true earning capacity. Additionally, temporary alimony can be awarded retroactively to the filing date when a motion was pending.

Simpson v. Simpson (2025)
Supreme Court of Connecticut, SC20988

Emphasized that ambiguous alimony terms in separation agreements require examination of extrinsic evidence. Courts will enforce the parties' original intent and not rewrite clear agreements.

O'Brien v. O'Brien (2017)
326 Conn. 81

Fault can be considered when it has economic consequences. Marital misconduct affecting economic circumstances is relevant under CGS § 46b-82.

Connell v. Connell (2014)
313 Conn. 158

Cohabitation may be grounds for modification or termination of alimony if it alters the recipient's financial needs.

Connecticut Alimony FAQs

Is there a formula to calculate alimony in Connecticut?

No. Connecticut has no alimony formula. Judges use the 20+ factors in CGS § 46b-82. This calculator provides estimates based on case law patterns.

What changed with the 2026 case R.D. v. G.D.?

The Appellate Court clarified that post-separation income increases can be considered in alimony calculations. Additionally, temporary support may be awarded retroactively to the filing date. This means even if income rose after separation, the court can base alimony on the higher, current income.

How does marriage length affect alimony under CGS § 46b-82?
  • Under 5 years: Alimony uncommon, brief if any.
  • 5-15 years: Proportional durational alimony.
  • Over 20 years: May be indefinite/permanent.
What happens if recipient cohabitates?

Alimony may be reduced/terminated if cohabitation changes financial needs. Payor must file a motion. Remarriage automatically terminates alimony.

Are alimony payments tax-deductible?

For agreements after Dec 31, 2018: No – not deductible for payor, not taxable for recipient.
