8. An electronic signature application server device that comprises a memory device and a processor that is operatively coupled to the memory device, wherein the processor is configured to execute instructions stored in the memory device that, when executed, cause the processor to carry out an electronic signature process that comprises: receiving, by the electronic signature application server device, from a document sender, a document containing a fixed document term and a variable document term, wherein the document sender has indicated that a document recipient is not allowed to modify the fixed document term, while the variable document term is associated with a parameter that can be set by the document recipient; receiving, by the electronic signature application server device, from the document sender, a condition on the variable document term, wherein satisfaction of the condition depends on the parameter set by the document recipient; defining, by the electronic signature application server device, a recipient's signature block at a first location in the document that is configured to receive a signature of the document recipient; defining, by the electronic signature application server device, an automatic signature block at a second location in the document that is configured to receive an automatically generated electronic signature authorized by the document sender; sending the document from the electronic signature application server device to the document recipient; receiving, by the electronic signature application server device, from the document recipient, the document, wherein the document received from the document recipient includes the signature of the document recipient positioned in the recipient's signature block; making, by the electronic signature application server device, after the document is received from the document recipient, at least one of (a) a first determination that the fixed document term has been modified from its state when the document was sent to the document recipient, and (b) a second determination that the parameter set by the document recipient does not satisfy the condition; and in response to making at least one of the first and second determinations, sending a notification from the electronic signature application server device to the document sender that the document is at least partially unsigned.
11. The electronic signature system of claim 8 , wherein the electronic signature process further comprises generating, in an audit record administered by the electronic signature application server device, an audit entry indicating that at least one of (a) the fixed document term has been modified, and (b) the condition is unsatisfied.
