do i need a lawyer to transfer a deed to my wife

A competent real estate attorney would ask you why you wish to transfer the property to your wife so as to inform you of the ramifications of such a transfer. For example, if the property is encumbered by a mortgage, you will likely have to pay documentary stamp tax and may be triggering the "due on sale" clause of the mortgage.  More information from you would be needed to determine if such a conveyance is in your best interest. Another benefit of involving a competent real estate attorney is that the deed and any related documents would be prepared and recorded correctly. The foregoing is specific to the law and procedure in Florida.  This response does not constitute legal advice as the facts presented are limited and unstated facts will likely impact your particular situation. This response is intended for general education only and does not create an attorney-client relationship. Please schedule a consultation with a local attorney for more specific and detailed answers to your legal issues.
