Hello, I have a document that needs to be digitally signed by two people. The digital signatures need to be invisible and the document needs to be locked to prevent future changes. How can I do this?
My second question is that I have had signed documents in the past that, upon opening, always indicated that there are problems with signatures, but then when I click validate, all signatures are found to be valid. Is there any way to have everything be valid as soon as the document is opened without having to validate all the signatures?

If you are going to use Digital signature then you have to place multiple signature fields on the document. And under the Field properties > Signed Tab, make sure you are not locking the document. Once the final signer signs the document He/She can choose to lock the document. how can I lock a document after signing it with acrobat reader DC
