Roommates are not on the lease, not paying rent, and refusing to leave
My roommates have been with me for at least 3 months now, have never paid rent, nor have they paid utilities. I have asked them several times to leave and they agreed that they would be gone by April 15. It is now April 17 and they have informed me that they are not leaving and if I want them to leave I will have to get them an eviction notice. They are not on the lease nor are any of the utilities in their names. They had made an agreement (written, I must add) with the landlord that they would be out by April 15. That agreement was written and agreed upon almost a month ago. If they are not paying rent, are not on the lease agreement, and have agreed to leave by a certain date, do I still have to get an eviction notice if they change their minds and decide not to leave?
If it makes it easier I live in Jackson County, in Georgia. I know it varies by state, I'm just not sure if it's also by county.
