When I’m required to sign and mail in a signature form, do I have to print and mail the entire document or just the signature page?

Only the signed signature page needs to be sent through the mail. The law firm will provide the remaining pages for the final form based on the reviewed and approved content that they have drafted. You should find an option to download only the signature page to the right of the specific form. Envoy Customer Experience can assist you with locating/providing the extracted signature page.
