Last Wednesday the Governor of Colorado signed into law Senate Bill 16-150. This bill closes a gap between civil unions and marriage. The bills clarifies that parties to a civil union are eligible to marry one another, without first having to dissolve their civil union. The period of time that the parties are involved in their civil union merges with the time of the subsequent marriage so that under the Uniform Dissolution of Marriage act the duration of the subsequent marriage includes the time the parties were in a civil union. Parties to a civil union may not enter into a marriage with another party without first dissolving the civil union. Doing so would constitute bigamy.
