Do I need grounds to file for divorce in Colorado?

Colorado is a no-fault state for purposes of divorce, so the only grounds you need to dissolve your marriage is stating that the relationship is irretrievably broken. The former bases for divorce, such as adultery, cruelty, or desertion have been repealed. Just one spouse needs to allege the breakdown of the relationship for the court to grant a divorce, so there are no defenses or strategies that the other may use to stop the process. If a person wants out of the marriage, the court will allow it, and if the other party agrees it makes a non-contested divorce easier.
