What is the procedure in FL to evict a tenant, who did not leave when the lease ended

[Celebra Queen]

Hello, asking for help with the advise about new law signed by the governor that allows to evict squatters using sheriff's help. If the tenant extended the lease twice, but when it ended, he is still located in the house refusing to leave. We contacted the tenant by email, by texting, and once talking telling that he has to leave at the end of the lease, but now the tenant does not want to communicate and does not pick up a phone. His wife, who has her house 20 minutes away, is also coming to the house without a lease agreement. Are they technically become squatters now? We tried to find a proper form for the eviction notice - as, if I understand correctly, once eviction notice is posted, we could ask sheriff's office to help us to remove the tenant. So a question is - please guide me to the proper eviction form that indicate to leave the property as the lease ended. We are in touch with the attorney, but  I decided to check here to get a form faster if someone could guide to the proper form location. 

Do I understand correctly that we cannot turn the electricity and water off, despite that it is under the owner name, not under tenant?

Any other advise on how to proceed?
