Official abstract text for this publication.
In various implementations, an electronic signature platform implements an electronic signing workflow that includes receiving, from a signer device, annotations made by a signer role to an electronic document in response to a request to sign the electronic document. A reply is received, from an advisor device, is made by an advisor role and is responsive to the annotations. Based on providing the reply to the signer device, an electronic signature is received that is provided by the signer role in response to the request to sign the electronic document. An audit trail is maintained that includes descriptions for events associated with the electronic signature, and timestamps associated with the events. The annotations and the reply are recorded by one or more of the events.

What is claimed is: 1. A computer-implemented system for implementing an electronic signing workflow comprising: an electronic signature platform that maintains a plurality of predefined roles comprising a signer role and an advisor role, each role having a different set of permitted job functions enforced in electronic signing workflows, the electronic signature platform comprising one or more processors and memory, coupled with the one or more processors, having executable instructions embodied thereon, which, when executed by the one or more processors cause the electronic signature platform to: receive, from a signer device, annotations made by a first user identity based on the first user identify having the signer role, the annotations made to an electronic document in response to a request to sign the electronic document, the response corresponding to a user selection by the first user identity of an option in an electronic signing application to request review by the advisor role prior to the first user identity responding to the request with an electronic signature; receive a user made assignment of a second user identity to the advisor role; receive, from an advisor device, a reply made by the second user identity that is responsive to the annotations and the requested review, the annotations provided to the advisor device based on the user selection of the option and based on the second user identity having the advisor role; based on providing the reply to the first user identity, receive the electronic signature provided by the first user identity using the electronic signing application in response to the request to sign the electronic document; and maintain an audit trail comprising descriptions for a plurality of events associated with the electronic signature, and a plurality of timestamps associated with the plurality of events, one or more of the plurality of events recording the annotations made by first user identity and the reply made by the second user identity based on the receiving of the annotations and the receiving of the reply, wherein the electronic signature platform is further caused to: receive, from a third user identity, the request to sign the electronic document based on the third user identity having the sender role; based on the third user identity having the sender role, receive, a request from the third user identity to remind the first user identity of the request to sign the electronic document; and automatically transmit a reminder notification to the second user identity based on determining that the second user identity has failed to provide the reply, based on the second user identity having the advisor role, and further based on the user selection of the option. 2. The computer-implemented system of claim 1 , wherein the electronic signature platform is further caused to receive, from a third user identity having a sender role, the request to sign the electronic document, the third user identity assigning the first user identity to the sender role based on the third user identity having the sender role. 3. The computer-implemented system of claim 1 , wherein the audit trail comprises one or more links to the annotations and the reply. 4. One or more computer storage media having a plurality of executable instructions embodied thereon, which, when executed by one or more processors, cause the one or more processors to perform a method comprising: maintaining, by an electronic signature platform, a plurality of predefined roles comprising a signer role and an advisor role, each role having a different set of permitted job functions enforced in electronic signing workflows; providing a request to a signer device for a first user identity to sign an electronic document based on the first user identify having the signer role; receiving, from the signer device, annotations made by the first user identify to the electronic document; receive a first user made assignment of a second user identity to the advisor role; receiving, from an advisor device, a reply that is responsive to the annotations, the reply made by the second user identity based on being assigned to the advisor role; receiving an electronic signature provided by the first user identify based on the first user identity having the signer role, the electronic signature being in response to the request to sign the electronic document after providing the reply to the signer device; and in response to a request from the first user identity, transmitting an audit trail to the signer device comprising one or more descriptions and one or more timestamps corresponding to the annotations made by the first user identity and the reply made by the second user identity based on the receiving of the annotations and the receiving of the reply, wherein the electronic signature platform is further caused to: receive, from a third user identity, the request to sign the electronic document based on the third user identity having the sender role; based on the third user identity having the sender role, receive, a request from the third user identity to remind the first user identity of the request to sign the electronic document; and automatically transmit a reminder notification to the second user identity based on determining that the second user identity has failed to provide the reply, based on the second user identity having the advisor role, and further based on the user selection of the option. 5. The one or more computer storage media of claim 4 , wherein the method further comprises receiving, from a third user identity having a sender role, the request to sign the electronic document, the third user identity assigning the first user identity to the sender role based on the third user identity having the sender role. 6. The one or more computer storage media of claim 4 , wherein the audit trail comprises one or more links to the annotations and the reply. 7. The one or more computer storage media of claim 4 , wherein reply comprises annotations made by the second user identity to the electronic document in response to the annotations made by the signer role to the electronic document. 8. The one or more computer storage media of claim 4 , wherein the method further comprises in response to a request from a third user identity and based on the first user identity having a sender role, transmitting the audit trail to the first user identity, wherein the first user identity is denied access to the annotations and the reply based on one or more permissions associated with the sender role. 9. The one or more computer storage media of claim 4 , wherein the annotations and the reply are embedded within one or more versions of the electronic document. 10. The one or more computer storage media of claim 4 , wherein the method further comprises receiving, from the signer device, an identifier of the second user identity to act as the advisor role for review of the annotations prior to the receiving of the electronic signature. 11. The one or more computer storage media of claim 4 , wherein the method further comprises transmitting, to the second user identity based on the second user identity having the advisor role, a notification of a user selection of an option, by the first user identity, to provide the annotations to the advisor role for review prior to the receiving of the electronic signature, the notification comprising a user selectable link to the annotations. 12. A computer-implemented method for implementing an electronic signing workflow, the method comprising: receiving, from an electronic signature platform, a request for a first user identity a signer role to sign an e
