If you over serve a guest, the damage they do can end up coming back to you. Most states now have social host liability laws in place, which can hold hosts liable for any property damage caused by their intoxicated guests. This can range from something minor, like a mailbox being run over to much more serious offenses. “Social host liability laws vary widely from state to state, but most of these laws offer an injured person, like the victim of a drunk driver, a method to sue the person who served the alcohol,” explains Worters. “While a social host is not liable for injuries sustained by a drunken guest (as the guest is also negligent), the host can be held liable for harm to third parties, and even passengers of the guest who have been injured in their car,” says Worters.
