NEW YORK (AP) -- Parents of teens: If you think a drinking disaster at your kid's party can't happen at your house, not with your kid, because he's a good kid, it's time to wake up and smell the whiskey bottle tossed on your lawn.

Because of the high risk of underage drinking and driving this time of year, many parents open their homes to partying teens as a way to keep them off the roads. What some may not know is that liability laws can leave Mom and Dad vulnerable to lawsuits, fines and even jail time if underage drinking is found to be going on under their roof.

Parents can get in trouble even if they didn't know about the drinking.

That's what a Menlo Park, Calif., father says he is up against.

Bill Burnett, a Stanford University professor, was arrested the night after Thanksgiving over a basement party thrown by his 17-year-old son to celebrate a big high school football win.

Burnett said he and his wife had forbidden alcohol at the party and were upstairs at the time police received a call about possible drinking by minors. In fact, he said, he had twice made his way to the basement to check on the merry-making.

He spent a night in jail and was booked on 44 counts of suspicion of contributing to the delinquency of a minor. Each misdemeanor count carries up to a $2,500 fine and nearly a year in jail.

Burnett questioned the deterrent value of laws that hold parents legally responsible even if they didn't know there was alcohol at the party.

"In this case I think arresting a parent isn't going to prevent kids from drinking," he said on the "Today" show.

Eight states have specific "social host" laws that say parents can get in trouble if underage guests are drinking, even if no one gets hurt, according to the National Institutes of Health. (Some of those states allow parents to serve alcohol to their own children in some situations.)

Sixteen other states have laws that hold Mom and Dad legally responsible for underage drinking under certain circumstances - for example, if a teen who drank at their home got into a car accident, NIH said. In other states, parents can get in trouble under more general liability laws.
