Marriage Rules in Colorado
Requirements: No blood test required.

You can marry immediately after your marriage license is issued, and your license is good for 30 days. For more details, check your county clerk’s office.
Common law marriage: Yes. A couple must intend to be married, live together for a significant period of time, and hold themselves out as a married couple.
Community property: No.
Same-sex marriage: No.
Colorado Divorce Rules
Grounds for divorce: No-fault. However, fault may be considered by the court as a factor in dividing property or awarding alimony.
Residency requirement: At least one spouse must be a resident of Colorado for 90 days before filing for divorce.
How property is divided: Equitable division.
Child Custody Rules in Colorado
Child custody guidelines: Colorado courts begin with a presumption that it’s best for a child to have frequent and continuing contact with both parents after a divorce. If possible, judges want to support joint custody arrangements.
Colorado Child Support
Child support guidelines: Colorado requires all parents to support their children. The amount of child support depends primarily on each parent’s income and other resources and how much time each parent spends with the children.
