if you don't have a lease agreement, you are renting only short term. plus you forfeit any rights in doing so. any long term (3 months or more) must be accompanied by a valid agreement, and it's the responsibility of the landlord to provide one. Whole point is in the end if the landlord creates the proper contract, they can avoid any trouble and cancel and evict by the terms therein. Otherwise, they have to follow the common law. Extortion, obstruction, and forcing eviction are all criminal acts. Mediating and finding a resolution is always an option.
