Lease or no lease in Florida

[Donna M.]

Have a tenant with no lease for a decade. He does pay but may not pay the increase . I have nothing in writing.  I inherited tenant.  I will be finally raising rent $200. If he doesn't pay the rent increase, I will evict. My question is, am I better off if I have to go to court in Florida to evict later to have a new month to month lease in writing to show the judge or stay without a lease and just tell the tenant verbally the rent increased $200.  Not sure which way i have an advantage if I have to go before a judge to evict. How do the judges respond to a landlord with no signed lease in writing? I want the option that is easier to evict if I have to. He can be spiteful.
