Alcohol Service
Dram Shop and Liquor Liability in Ohio
Knowing service to a noticeably intoxicated person
Ohio's dram shop statute is Ohio Rev. Code § 4399.18. A person injured by an intoxicated patron may claim against a liquor permit holder only by showing that the permit holder or an employee knowingly sold alcohol either to a noticeably intoxicated person in violation of R.C. 4301.22(B), or to an underage person in violation of R.C. 4301.69.
Ohio courts require proof that the permit holder or its employee actually knew the patron was noticeably intoxicated; that knowledge may be shown through circumstantial evidence. A permit holder is not liable merely because a patron was served and later caused harm.
Noticeably intoxicated means clear, observable signs — slurred speech, stumbling, aggressive behavior. Because the statute keys to an observable condition and a knowledge element, the case usually resolves on surveillance, service records and what staff and other patrons saw.
This summary is general information for counsel, not legal advice. Statutes, regulations and case law change; counsel should confirm the law in effect on the date of loss. Ryan Dahlstrom's opinions address operational practices measured against hospitality industry standards; he does not offer opinions on the law.
