Email showing Taxpayer's name

When I am Sending a document for e signature by DocuSign and the attached email shows the main taxpayer’s name instead of spouse or dependent’s name. i.e. I have a father (main), Mother (spouse) and two kids. how can I get it to show the kid’s name, who is signing the document instead of his/her father’s name?
