Dear XXXXXXXXXXXXX,
Under the general rules that make a property owner responsible for all that occurs on their property, with their consent or permission, If a homeowner permits another person to host a party on their premises and an intoxicated guest later leaves that party and harms another or is harmed while at the party due to their intoxication, it is possible that both the host of the party and the homeowner may be sued and found liable. You can read about such a situation in the ME case of Peters v. Saft, 597 A.2d 50 (1991), this case does not appear to be available online free of charge, but you can contact the ME Supreme Court for a copy of the case.
The general rule is that when a person allows another to stay at or use their home (unless you mean to say your child illegally "borrowed" your home) they may be held liable for activities that take place while another is using or staying in the home.
