In Connecticut: Parenting time directly reduces child support obligations when a non-custodial parent reaches 146 overnights per year (40% timeshare) under Conn. Agencies Regs. § 46b-215a-5c(f). The court calculates relief using the shared physical custody deviation (substantially equal care). Standard rotational schedules such as 2-2-3 (182 nights) qualify for full shared-custody adjustments.

Connecticut Custody Overnights FAQ

Does Connecticut have an automatic shared custody formula?

No. Connecticut does not provide an automatic statutory formula for shared custody. Instead, spending 146+ overnights (substantially equal care) allows the judge to grant a downward deviation if financial fairness warrants.

Can Connecticut courts deny a deviation despite 50/50 custody?

Yes, if the lower-earning parent cannot maintain sufficient housing or if the child's standard of living would be severely degraded in the primary home.
