Recording a deed protects the rights of the grantee. I believe in Florida, the statute protects the rights of the first one who records if they are a subsequent purchaser for a valuable consideration and without notice. This means that if a person pays for the property and had no idea that there was another deed out there and he records first, the property is his. Of course the grantor of this (second) deed may be prosecuted for fraud and/or is liable in tort to the grantee of the first deed, but that is a seperate question.
