I live in Denver, CO and 11 months ago my brother moved to Denver supposedly to take a job here and came to stay at my house as a guest since it was near the holidays and his job was not going to start until after the first of the year. He has remained at my house now for a 11 months and never paid any rent, never paid any utilities or paid for any groceries. The job fell through and it was not until about a month ago that he finally found a job. I have told him that he needs to be out by December 1st but he does not seem to be moving forward with finding a place to live.
What rights do I have? Do I have to formally evict him?
