I have a leased apartment and have allowed someone to move in, who is not on the lease agreement. Recently, they have stopped paying rent and moved a third party into the apartment. It's been vocalized that it's not ok for rent not to be paid and for this third party to live in the apartment. What kind of recourse do is there to get both people out of the apartment? From what I have read, our landlord would need to assist OR evict all of us. My landlord and I have a good track record, but I have not been renting there for more than a year. I pay rent on time and in full, even though not receiving my roommate's portion of the rent and maintain the property, keeping it neat and tidy. I report any damages and he has been great about fixing them quickly. My roommate is truly irresponsible, not paying rent OR utilities, not cleaning up after themselves and, now, moving someone else in with no notice or permission from anyone. Suggestions would be tremendously appreciated.
