If getting a mortgag, your lender will protect their interests so you may not need an attorney.
I realize that many of our Buyers in Florida come from other states with different laws. In New York, Connecticut, and Massachusetts, for example, all closings are handled by attorneys.
The law does not require that you have an attorney's office conduct your closing in Florida. Most of our closings take place with title companies, who have their own attorneys who review your closing documents and title insurance documents.
However, that being said, I would also add that an attorney CAN conduct your closing, if you want. In my county (Volusia County, Florida), it's customary for the person buying the owner's title insurance policy to select the closing agent. In a normal closing, not a short sale or foreclosure, that person is usually the Seller.
As a Buyer, you can purchase the owner's title insurance policy, and thereby choose the closing agent, if you wish. Or, if you just want an attorney of your choosing to review your paperwork, you can do that. It's up to you.
