Parties to the real estate transaction are defined and parties may register with the server. The server receives a first unique identifier for the first party, a unique identifier for the real estate interest, a first purchase amount for the real estate interest, a second unique identifier for the second party, and a second purchase amount. The server compares the first purchase amount with the second purchase amount and the server may transmit a request for a notarization document.
