A month ago I had a get together at my apartment in the end someone got sick and threw up on a car in the parking lot. The next day we received a threatening note from the owner saying that next time we had a party we would have a visitor.

Now we have a fine and my complex is claiming they will refuse to accept our rent until the fine is paid. The fine composes of $30 for the owner of the car having to get it detailed and $100 for a “disturbance fine” that would go to the apartment.

I would like to dispute the $100 portion of the fine based on the fact that none of our neighbours ever told us we were being loud and the fact that the owner of the car never came to see us.

Is what the apartment complex is doing even legal since the “fine” was a recent addition to my contract?
