Whenever:(1) Any person contracts by written agreement to purchase real property before July 1, 1972, and the final maturity of the obligation is not ascertainable from the record of the contract, or accepts an assignment of such a contract, but
(2) Even though the existence of the contract or assignment appears from the record of the instrument or by reference to it in another recorded instrument, such person has not recorded a deed to the property or a judgment recognizing the person’s rights to the property and is not in actual possession of the property as defined in s. 95.16, then the person and those claiming under the person shall have no further interest in the property by virtue of the contract or assignment. In these circumstances, the record of the contract or assignment, or other record reference to either, shall no longer constitute actual or constructive notice to any person acquiring any interest in the property.
