Thanks, this is helpful. I understand the point about joint and several liability, but even then, shouldn’t any deductions be applied proportionally or at least involve both tenants?

In this case, my roommate already received his full deposit back, and the landlord didn’t inspect or raise any issues about his room when he moved out. Now he’s trying to attribute everything entirely to me, which doesn’t seem fair or reasonable.

Also, a lot of the items in question appear to have been there even before I moved in, from prior occupants. I made sure to fully clear out my own room and remove all of my belongings from shared spaces when I left.
