The state of Colorado treats domestic violence cases with the utmost seriousness as these crimes have a profoundly negative impact on victims and society. A domestic violence (DV) charge in Colorado is unique in that it is not considered a crime in and of itself; rather, DV is an enhancement that can be applied to various misdemeanors and felonies.
In other words, the simple answer to the question of whether domestic violence is a misdemeanor or a felony in Colorado is: it is neither. This enhancement can be applied to all types of crimes depending on the unique circumstances at hand.
