In Massachusetts, a person under 21 can legally drink with a parent, but the exception is narrow: a parent or grandparent may furnish alcohol only to their own child or grandchild, and only on property the adult owns or controls. Anywhere else, or with anyone else’s child, the same drink becomes a crime.
Who the Exception Covers
The rule is built into the definition of “furnish” in Chapter 138, Section 34 of the Massachusetts General Laws. Furnishing alcohol to a minor means knowingly supplying it to someone under 21 or allowing them to possess it on property you own or control. The statute exempts a parent or grandparent providing alcohol to their own child or grandchild under those conditions.1General Court of Massachusetts. Massachusetts General Laws Part I, Title XX, Chapter 138, Section 34
The relationship has to be direct. Stepchildren, nieces, nephews, and your child’s friends are not covered, even if the other parent gives permission. Providing alcohol to someone else’s minor makes you a furnisher under the statute.
Where the Exception Applies
Location is the second half of the rule. The exception only works on property the parent or grandparent owns or controls. A family home, a backyard, or a vacation rental in the adult’s name qualifies. A friend’s house, 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, bars, and hotels are off-limits regardless of who’s at the table. Section 34 separately prohibits anyone from procuring alcohol for an underage person at an establishment with a pouring license. A parent can procure alcohol for their child at a package store, brewery, or winery, meaning places that sell sealed containers for consumption elsewhere.2General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34
What Happens to the Minor
The parental exception shields the parent from a furnishing charge, but it doesn’t automatically shield 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 the parent is present and provided the alcohol at home, this statute doesn’t apply. The moment the minor is somewhere else, or the parent isn’t with them, it does.3General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34C
The penalties look modest on paper but hit hard in practice:
- First offense: a fine of up to $50.
- Second or subsequent offense: a fine of up to $150.
- Any conviction triggers a mandatory 90-day driver’s license suspension, reported by the court directly to the Registry of Motor Vehicles.3General Court of Massachusetts. Massachusetts General Laws Chapter 138, Section 34C
For a teenager who drives to school or work, losing a license for three months is usually the real punishment.
What Happens to the Adult Who Steps Outside the Rule
An adult who provides alcohol to someone else’s minor, or to their own child somewhere they don’t 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
Parents most often run into this when hosting a party where their teenager’s friends drink. You don’t have to hand anyone a beer. Knowingly allowing minors to possess alcohol on your property is enough.
Social Host Liability
Criminal charges are only one layer. Massachusetts recognizes social host liability, which means a parent who provides or allows alcohol at a gathering can be sued civilly if an intoxicated minor later causes injury. Violating the social host law can establish negligence, opening the door to claims for medical bills, lost income, and other damages.4Mass.gov. Preventing Underage Drinking Action Plan for Parents
To hold a host civilly liable, a plaintiff generally has to show the host controlled the supply of alcohol, made it available, or served it. Simply owning the house where teenagers secretly drank isn’t automatically enough, though courts do look at whether the host took steps to prevent access. Judgments in these cases can reach six or seven figures.4Mass.gov. Preventing Underage Drinking Action Plan for Parents
Many homeowners’ policies limit or exclude coverage for alcohol-related incidents, so a civil judgment can come straight out of pocket.
Common Ways Families Misread the Rule
The most frequent mistake is treating the exception as broader than it is. A few situations that fall outside the protection:
- Serving your child’s friend a glass of wine at a family dinner. Verbal consent from the other parent does not create a legal exception.
- Ordering your teenager a drink at a restaurant. No establishment with a pouring license can legally serve someone under 21, and a parent can’t procure it for them there either.
- Providing alcohol at a vacation rental booked in your child’s name. The property has to be owned or controlled by the adult doing the furnishing.
- Sending your 19-year-old home with a bottle of wine. Once they leave your property without you, they’re possessing alcohol without a parent present, which exposes them to a Section 34C charge and the 90-day license suspension.
The exception only holds when the right adult provides the alcohol, to their own child or grandchild, on their own property, while present. Remove any one of those pieces and the legal cover is gone.
