If the pays rent monthly, then you have a whatu2019s called a u201cmonth to monthu201d rental agreement.In these types of situations, where there is no written lease, you still need to give the person whatu2019s called a Thirty Day Notice.The Notice should simply say your name and address, the other personu2019s name and address, the date, and that you are ending the rental agreement at the end of the month.Post the Notice on the personu2019s door and keep a copy for yourself.If the person acts out, or scares you in some way, call the Police and show them a copy of the notice. But do not enter the personu2019s room before the time is up.If the person does not leave before the 30 days is up, you will want to consult with a lawyer because you will have to go to court to get them evicted from your property.
