Alcohol Service
Dram Shop and Liquor Liability in Massachusetts
Negligence built on the service prohibition
Massachusetts does not have a standalone civil dram shop act. Claims are brought in negligence based on M.G.L. c. 138, § 69, and are subject to the procedural requirements of M.G.L. c. 231, § 60J. M.G.L. c. 138, § 69 prohibits selling or delivering alcohol on licensed premises to an intoxicated person, and civil claims are framed as negligence built on that prohibition.
Massachusetts courts have long recognized that serving an intoxicated patron can be a foreseeable cause of harm to third parties, including harm caused by drunk driving. Because the claim sounds in negligence, the standard of care for a reasonably prudent licensed operator is directly in issue — which is where industry standards, written policy and training practice do the work.
Licensing authorities can also require liquor liability insurance as a condition of modifying, reinstating or renewing a license where a licensee has served a minor or an intoxicated person, which produces a regulatory record that often runs alongside the civil case.
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.
