A bill currently being considered by the Colorado legislature proposes that businesses licensed to sell alcohol to adults be permitted to sell alcohol to adults under 21 when the underage person’s parents are present with the underage person and purchase the beverage for that person.
As the law currently stands, it would be illegal for a restaurant to provide anyone under 21 with alcohol regardless of who is present with them.
However, current law does allow an underage person to possess or consume alcohol when they are legally present on private property and their parent is on the property and consents to their consumption of alcohol.
It is currently illegal for anyone under 21 to enter a liquor store. It is also illegal to create and/or use a fake ID.
