I think you are worrying without reason. You assume she will be drinking and assumptions are not the way to make judgments. I would just tell her that there is no drinking in your home, anything she does outside is not on you.
The advice I have given does not bind the parties in any manner and is merely given as a courtesy.
You could be charged however they would have to prove that you allowed or provide the alcohol which would be difficult if you didn't. What you should know is that you shouldn't:)
This is not legal advice. If order to give you legal advice i would need to see the Tickets and talk to the court first. Good luck:)
You're definitely being paranoid. As long as you don't personally give her any alcohol or allow her to drink alcohol in your home, you can't be liable for what she does outside. And even if you did provide her with alcohol or allow her to drink it in your home, the odds of the police becoming involved are pretty slim.
