Parents are generally responsible for (have liability for) intentional, willful, and malicious property damage done by their minor child. Parents may also be liable for the negligent acts of their minor child if the parents were (1) negligent in supervising the child (negligent supervision), or (2) negligent in entrusting the use of a car, gun, boat, motorcycle, or other item (often called an instrumentality) to the child (negligent entrustment).

These parental liability laws vary from state to state; often include age and monetary limits; and may be included in your state’s statutes—often in the family code.

In New Hampshire, parents can be held liable for the intentional or willful property damage caused by their minor children under certain circumstances. The state's parental liability laws are outlined in New Hampshire Revised Statutes Annotated (RSA) 507:8-a, which holds parents or guardians responsible for willful or malicious acts of their children that cause damage to property or bodily injury. The statute limits parental liability to a maximum of $5,000 for any such act. Additionally, parents may be liable for negligent supervision if it can be shown that they failed to exercise reasonable care in supervising their child, which resulted in damage or injury. Similarly, under the doctrine of negligent entrustment, parents could be held liable if they negligently allowed their child to use an instrumentality, such as a car or firearm, and the child caused damage or injury with it. It's important to note that these laws are subject to interpretation by courts, and the specific circumstances of each case can affect the application of liability.
