I live in an apartment with my fiance where there is no lease. It's $500 a month and we have a roommate that pays $250 of that $500 to me and I go pay the landlord. I recently found out that he's a junkie and he's been shooting up in the apartment. I live in New York. What are the laws regarding evicting him? Do I have to give him 30 days notice although what he's doing is illegal and neither one of us has a lease with the landlord? Should I call the cops and let them deal with it after they find drugs and paraphernalia in his room? I'm worried about the safety of my fiance and I if I end up taking that route. I just don't know what the best way to go about this is. Please help!
