<prompt> Human: So in the past month, my sister, in a car registered to my parents, got a parking ticket on my universitys campus. My sister is not a student of the university, but I am. The university ran the registration on the vehicle, found out it was registered to the same address that is on my record at the University, and are now trying to get me to pay the ticket and threatening to prevent me from registering for classes if I do not pay it. I called the parking office and told them that I did not believe it was legal to try and collect debt from me that was accrued by a family member, and they were very quick to change the subject. My sister has no money to pay the ticket, and I do not want to pay a debt that isnt mine. So is there some debt collection law out there that I can present to them that helps my argument? If this is the wrong subreddit for this please let me know, and if you know of another where I might find my answer please direct me there. Thanks!  <response>: No, it is not legal. There could potentially be some recourse if you were the owner of the vehicle but living at the same address as someone else does not make you responsible for their debts.Go there in person. Ask for proof that it was your vehicle that received the ticket. When they can provide none, tell them to remove it from your account and go after the vehicles owner. If they refuse, tell them that youll be contacting your attorney to resolve this for you.
