is it possible to auto populate fields from a desk ticket into a form?

currently the user submits a form, it goes to desk, back and forth, then they agree(hopefully). If they agree id like to have them sign something. 

id like to make it as easy as possible for both parties. so id like to be able to then create a form with the contacts info and all they do is sign and resubmit a form.

also if theres a better solution im all ears.
