Legal Question in DUI Law in Colorado

Re: Alcohol at weddings

First, you are not "responsible" for a guest who gets a DUI. However, you may be found responsible for a guest who gets into an accident. Who is providing the alcohol at your wedding? If the alcohol is provided by a hotel or a catering company, for example, you would be more protected from any liability; the liability in that case would more likely fall on the hotel or the catering company. Having your guests sign a waiver is also helpful, although it's not going to insulate you 100% from any liability. (It's also not very hospitable.) The more appropriate thing to do is close the bar at a reasonable time, and openly and loudly remind everyone to drink responsibly and do not drink and drive. Also, take reasonable steps to ensure that people do not drink and drive, such as appointing a key monitor.
