Combining Docusigned documents in AdobePro

The more than likely reason you cannot modify the agreement (in this instance combine documents) is because the document is sealed and certified. I would consult with your legal team before doing the following, as the certification my be required for your line of work....

Solution: You could strip the certification by printing the agreement to a PDF.... this will flatten the document and remove the certification. Now if you open up the flattened agreement in Acrobat you shouldn't run into the issue of cobining the two PDFs into one.
