Adobe Sign- How to to add an additional layer for signature on secured document?

I am using forms downloaded from an open public court website. When they download for filling on my computer, it opens as (SECURED). When I fill in the information necessary to the form with the fillables that the court put in, then try to send it out for signature by another party (not the court), Adobe does not allow this to occur. I understand the security level on the document, but is there really no way to add an additional layer for signature that would be accounted for in the audit trail? Is there something I am missing that would allow me to send out a secured document for signature?
