Drinking under 21 with a parent in Massachusetts is legal in one narrow situation: a parent or grandparent provides the alcohol to their own child or grandchild, and it happens on property the parent or grandparent owns or controls. That exception is written into the definition of “furnishing” alcohol to a minor under Chapter 138, Section 34. Step outside any of its conditions and the adult faces criminal charges, civil liability, or both.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XX, Chapter 138, Section 34
Who the Exception Covers
Furnishing alcohol to a minor, under Section 34, means knowingly supplying or giving alcohol to someone under 21, or allowing them to possess it on property you own or control. The statute carves out parents and grandparents who provide alcohol to their own children or grandchildren.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XX, Chapter 138, Section 34
That is the entire family tree the exception reaches. Stepchildren, nieces, nephews, and your child’s friends are not covered, even if their parents say it’s fine. Providing alcohol to someone else’s minor child makes you a furnisher under the statute.
Where the Exception Applies
The parental exception only works on property the parent or grandparent owns or controls. Your house, your backyard, or a vacation rental in your name qualifies. A neighbor’s home, a public park, or a hotel lobby does not.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XX, Chapter 138, Section 34
Restaurants and bars are off-limits regardless of the parent-child relationship. Section 34 separately prohibits anyone from procuring alcohol for an underage person at establishments with pouring licenses, which covers restaurants, bars, and hotels. A parent can procure alcohol for a child, spouse, or ward at a package store, brewery, or winery, which sell sealed containers for off-premises consumption.2General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34
What Happens to the Minor
Section 34C makes it a separate offense for anyone under 21 to knowingly possess or carry alcohol while not accompanied by a parent or legal guardian. When a parent is present and has provided the alcohol at home, Section 34C does not apply.3General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34C
Outside that scenario, a minor caught with alcohol faces:
- A fine of up to $50 for a first offense.
- A fine of up to $150 for a second or subsequent offense.
- A mandatory 90-day driver’s license suspension on any conviction, reported directly to the Registry of Motor Vehicles by the court.3General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34C
The fines are modest. The automatic 90-day suspension hits hard for a teenager who drives to school or work.
What Happens to the Adult
An adult who provides alcohol to someone else’s minor child, or to their own child outside of property they own or control, commits a criminal offense under Section 34. A conviction carries a fine of up to $2,000, up to one year in jail, or both.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XX, Chapter 138, Section 34
The most common path to charges is hosting a party where a teenager’s friends are drinking. The statute reaches not just handing someone a drink, but knowingly allowing a minor to possess alcohol on your property.
Social Host Lawsuits
Criminal penalties are only half the picture. Massachusetts recognizes social host liability, meaning a parent who provides or allows alcohol at a gathering can be sued if an intoxicated minor later causes injury. The injured party can argue that violating the social host law establishes negligence, opening the door to claims for medical bills, lost income, and other damages.4Mass.gov.

Civil liability requires proof that you controlled the supply of alcohol, made it available, or served it. Owning the home where teenagers secretly drank is not automatically enough, but courts look at whether you took steps to prevent access. Judgments in these cases can reach well into six or seven figures.4Mass.gov. Preventing Underage Drinking Action Plan for Parents
Many homeowners’ policies exclude or limit coverage for alcohol-related incidents, so a civil judgment may come out of pocket.
Where Parents Lose the Protection
Most trouble comes from treating the exception as broader than it is. Scenarios that fall outside the law:
- Serving wine to your child’s friends at a family dinner. The other parent’s verbal consent does not create a legal exception.
- Buying your teenager a drink at a restaurant. No pouring-license establishment can legally serve alcohol to someone under 21, and a parent cannot procure it for them there.
- A vacation rental booked in your child’s name. The property must be owned or controlled by the parent or grandparent furnishing the alcohol.
- Sending your 19-year-old home with a bottle of wine. Once they leave with it and no parent is present, they are exposed to a Section 34C charge and a 90-day license suspension.
The exception works only when the right person provides the alcohol, to the right minor, on the right property, while present. Remove any one piece and the protection is gone.
