If you're in a transaction and someone outside of your account needs to sign either the Purchase Sale Agreement, Assignment(s), or the Allonge, there is a way to do that.

When executing the document, you are presented with four different ways to execute it. Choose the fourth option "Share Signature Pad", once this is chosen you're given the option to send the document to the signer.

The signer will receive an email titled "Signature Request: Purchase Sale Agreement". When opened the signer will be presented with a link to view and sign the document.

Clicking on that link opens a window for them to sign the document. Once they sign and submit, the executed document will show up in the transaction.

If an Assignment needs to be signed, the signer will be presented with a link to sign in to Proof and get the Assignment notarized.
