The style of your question suggests that you are (questioner is) the tenant attempting to dispossess a poperty owner by process of squatting. That is a misconception that many deadbeats have....except that the act of right of squat compels an owner to accept permanent tenancy. Squatting is a provision for lawful possession of utitled land upon the fulfillment of certain conditions. Simply living and paying rent, or not paying rent, for a period of time does not give cause for squatter's rights, unless a person had occupied a dwelling for so long as to have it seem that permission for permanent residency--a life estate--had been granted. But even then it is not squatting that is in question, it is whether or not the tenant has sufficient claim to enforce a fee lease or demand distress payment from owner. The main thing a landlord can do in the absense of any written agreement is to give notice of a tresspass, after which upon expiration of the required length of time. the police can be called upon to arrest and remove any trespasser so notified.
