A system and a method for creating and controlling electronic agreements. In general, the system includes a server and at least one client interconnected through a communications medium. In operation, the system only allows access to authorized users. Once a user gains access, the user inputs commands and data that are necessary to create an electronic document. Upon completion of the electronic document, the user can invoke a signature process. During the signature process, the parties to the agreement enter electronic signatures. The present invention operates to encrypt the electronic document and then encrypts each of the signatures using an encryption key that is based, at least in part, on the contents of the electronic document. This aspect of the system prevents the creation of fraudulent versions of the electronic document because any modifications to the electronic document will invalidate the encrypted signatures. Finally, the system operates to transfer the electronic agreement to a secure server. The server maintains the authoritative copy of the electronic agreement, thereby providing control of the electronic agreement.
