Can I forward the signature request email to someone else to sign?

You can use the Send to Someone Else feature to assign the responsibility to another person.  Using the Send to Someone Else option will switch the responsibility of signing from you to the other recipient, and the change in signing responsibility will be tracked in the document history.

The Send to Someone Else option is available from the signing process.  To use it, you should click the Review & Sign button in the email you received.  Once in the signing process, you'll have the option to send to someone else.
