Missouri law essentially bars this type of personal injury lawsuit against a homeowner for serving alcohol to guests. Why? To establish social host liability, a person injured in an accident caused by a drunk driver must prove a (1) civil duty not to furnish someone with intoxicating liquor, a (2) breach of that duty, and (3) the furnishing of alcoholic beverages to an individual caused the injuries or death resulting from the car accident. However, Missouri law does not currently impose a legal duty not to provide alcohol to someone, including minors. There is a criminal law against it, but it does not impose a civil duty.
