My question involves a roommate in the State of: Texas
My little sister who is in college needs me to cosign on an apartment lease for her. However, after talking with the apartment complex I found out that I am responsible not only for my sister, but her roommate as well. This has left us in quit a bind because her roommate's parents do not want to be responsible for my sister and I don't want to be responsible for the other girl.
Is there a legal document or something I can get drawn up between myself and the roommates parents stating that each party is responsible for their relatives portion of the rent.
I.E. If they cosign and my sister flakes out, they would have a legal document holding me personally responsible for any lost rent on my sisters behalf.
Thanks.
