Colorado has adopted the Uniform Parentage Act, codified at 19-4-101, et seq. Under that statute, and under the "Colorado long-arm statute" at C.R.S. 13-1-124, the Colorado paternity court has jurisdiction if the child or one of the parents lives in Colorado, and one of the following conditions is met:
- Personal service on the respondent parent within the state of Colorado (including a waiver of service),
- Personal service anywhere, if the child was conceived as a result of intercourse in the state of Colorado, or
- The respondent parent consents to the Colorado paternity court exercising jurisdiction.
Colorado paternity jurisdiction means Colorado can adjudge paternity, order the child's birth certificate changed, and order child support and birthing costs. Under the UCCJEA, only the child's home state can adjudicate custody and parenting issues. If Colorado is the child's home state, the Colorado paternity judge can also determine those parenting issues.
