Colorado utilizes an Income Shares model under C.R.S. § 14-10-115. Shared physical custody transitions from Worksheet A to Worksheet B once the noncustodial parent reaches 93 overnights (25% of the year).
Shared Custody & Overnights in Colorado
Under Worksheet B, once a parent has 93 or more overnights, basic support is multiplied by 1.5 to account for shared household duplication, then apportioned based on overnights and parental income ratio.
