Tenant At Will Form

I need to evict one of my tempting and I need help completing this form. They are tenant at will. I need the apartment for my son and his wife. I do not understand certain terms. Can anyone help me? I want to go out by August 1st and I decided to give them the notice on July 1st. Here's the review: 30 Days Notice to Quit

Blank # 5: The date given the number of days that you give them to leave after receiving the notice

You do not need to evict your tenant. Eviction is the forced displacement of a tenant who has not paid rent or has broken the rules of the lease. In this paper a trial and all - is the wrong document!

Instead, you want to issue a notice to vacate. First, do it in person. Give them more than 30 days so they have time to find a new place. Do not be a jerk about it. Tell them in person that the apartment is no longer available for rent after August 1, and you are very angry. Then tell them you have the official documents in the mail soon.

Whatever you do, do not serve with the above document. You have no reason to expel them, which can cause you serious trouble.
