Context: Florida, USA
I have a guest at my house who was supposed to leave after two weeks, but it has been months. They do not pay rent, or offer anything in exchange for being allowed to stay. We have an agreed upon final move out date, but considering they failed to move out the last 3 times we set a date, I want something legal and immediately enforceable if they don't move out this time.
They have agreed to sign a notarized move out agreement, but I want to be sure that the agreement is immediately enforceable + severe.
If I include that by breaking the contract, they will be trespassing if they are ever on my property, do I still need to go through the Unlawful Detainer process?
Also to show I'm serious this time, I want to include something that gives me permission to make their life hell if this agreement broken ($10-100k violation penalty or something), but I'm worried that including such an item might allow it to be thrown out as an unreasonable agreement in the case it has to go to court.
In short, what do I need to make sure is stated in this agreement, and what is the best way to make sure breaking this agreement is the worst mistake they can ever make?
