In many states a social host—including the guest’s employer—who does not charge an adult guest—18 years or older in some states and 21 years or older in other states—for alcoholic drinks and who does not serve the beverages under the authority of a license or permit—is not liable for the guest’s actions or injuries to himself or others.
But in most states an adult social host is liable for personal injuries and property damage caused by a minor to whom the social host provides or furnishes alcoholic beverages—especially if the social host knew or should have known the minor would drive a motor vehicle under the influence or if the minor was obviously intoxicated when the social host provided or furnished alcoholic beverages.
Laws regarding social host liability vary from state to state and are usually located in a state’s statutes.
In New York, social host liability is governed by the state's General Obligations Law. Under Section 11-100, a social host may be held liable for damages caused by the intoxication of a person under the age of 21 if the host knowingly provided alcoholic beverages to that minor or knowingly allowed the minor to consume alcohol on premises they control. However, for guests who are 21 years of age or older, social hosts generally do not have liability for injuries or damages caused by the intoxicated guest, unless the host's actions were reckless or intentional. It's important to note that these laws are subject to change and can be interpreted differently by courts, so it is advisable to consult with an attorney for specific legal guidance.
