In the state of Florida, when transferring the ownership of real estate, the seller must sign a deed granting the property to the new owner. Without a properly written, executed, and recorded property deed the title (ownership rights) might not be properly transferred from seller to buyer. Moreover, if the deed to a house does not conform to certain rules it could be found to be invalid. If the deed that transferred title to you is found to be invalid your ownership rights could be called into question.
