>A self-hosted digital signature system isn't worth anything in court; the other parties will simply reject the authenticity of any data held within it and the amount you'd have to spend to get that data into evidence would probably pay for several centuries of DocuSign's enterprise edition.
When self-hosting it - you can integrate it with AWS s3 Azure or Google Cloud files storage - those are the trustworthy third parties that provide the entire history of logs to ensure that the documents were not altered and signed at specific date/time with the specific content.
So bringing cloud storage providers as a thirdparty when self-hosting will bring enough evidences to the court to defend the signed documents.
How do you prove who actually signed the document? Docusign does this by only sending the signing link to the signer’s email. I don’t see how you could prove that no one else had access to that link if you’re self hosting.
