*Please note that there are now two systems for preparing real estate documents (Webforms) for electronic signature. It is very important that you pick the system that matches your electronic signing program as the two systems do not talk to one another. A document created in one system will not be editable in the other. Templates created in one system will not work in the other. If you use Authentisign, your documents/templates need to be created in TREB’s Instanet/Authentisign. If you use Docusign, your documents/templates need to be created in CREA’s WebForms/RealtorLink.
