My boyfriend was living with his grandmother for a year and half in a rent controlled city with favorable rent. She lived in that same apt for over 40 years. No lease was found and probably never existed. She recently passed away and he would like to move back and assume her apt. (he had been out of apt for 2.5 years). Does he have any rights at all to this apt? We would like to know before approaching the management company about becoming the new tenants.
