Have there been any court cases where a contract was considered void because the signature was digital? I’m really not sure under what basis one would make that determination. Signatures are mainly symbolic and provide nearly zero guarantees. Sure there’s some extra security you can build around signatures (eg.: docusign), but paper doesn’t really have all of that extra stuff.
