A parent is liable for a child’s negligent acts if the parent knows or has reason to know that it is necessary to control the child and the parent fails to take reasonable actions to do so. This legal theory is known as negligent supervision. Liability for negligent supervision is not limited to parents. Grandparents, guardians, and others with custody and control of a child may also be liable under these circumstances. There is usually no dollar limit on this type of liability. An umbrella or homeowner’s insurance policy may offer the adult some protection in a lawsuit.
