What is a signing certificate?

A signing certificate contains all of the signing details and acts as an added layer of security. With a signing certificate, you can track when your document was signed, the name of the document, who signed it, and where.

What if my client has someone signing on their behalf?

If your client is working with a trust company that will sign on their behalf, you can add the signer’s name to the preferred signature field. This will populate your documents with the seller’s name and information, and place the preferred signer’s name in the signature field to keep your deal moving.
