My boyfriend and three of is friend rented an apartment for a year and one of his friends stopped paying rent (and skipped town) at some point to where it added up to about $3,000 in unpaid rent...the landlord never asked my boyfriend or the other two roommates for any money and now the landlord is suing ONLY my boyfriend for what is now about $4,500... he just received the judgment in the mail...and from what I have heard from him and his 2 friends is that the landlord would never return their calls for anything (leaky pipe, sky light window leaky, etc.)...is there anything my boyfriend can do to either reduce the amount, besides asking his friends to chip in or suing his friends for some of the money, or get it dropped so he is not responsible?
