Both names on title but only 1 name on loan

My boyfriend has a home loan that is in his name(for his cousin) but him and his cousin are both on the title. His cousin is living there but since the grandma passed (she was paying for the cousin) he is no longer going to pay for the monthly amount. Is there a way for this person to be evicted since my boyfriend does not live there and his cousin is refusing to move out and pay the amount forcing the house to go into foreclosure? What are his options to not have this on his credit since the loan is in his name?

We advise never sign for somebody else like that...

If two or more owners cannot agree on what to do with a piece of property they may petition the court and the court will order a sale or refinancing etc. so that the one or more may get out of the property obligation and/or the other(s) may keep it etc.--it is often done-- (This is true in some cases even for equitable owners that have paid various amounts etc., but for various reasons, may not be on title.) You could threaten to take this action if need be. It may cause compromise which is of course what you need here now.
