Is Xodo Sign Legally Binding?

In order to offer the highest level of signer authentication, Xodo Sign systems will require signers to verify their identity using an SMS or custom PIN code as a 2nd factor (the E-Mail inbox is the first factor). Only upon successful entry of the code, Xodo Sign will show the document for the pending signature request.
If a Xodo Sign user chooses to enable In-Person Signing (signing in-person on a mobile device), all kinds of verification will be disabled and it will be the user's responsibility to verify the identity of all signers in person. Learn more about Signer Authentication.

All document data and signing metadata is stored securely on the cloud and its unique hash keys prevent document data from being manipulated retrospectively. Each document transaction is stored along with a unique key, which - if the content changed for any reason - would no longer be valid. This also makes it easy to legally prove that no tampering occurred during or after the signing of a document. Completed PDF documents are signed with a certificate, which means all parties can verify that the document they now own was created by Xodo Sign and was not tampered with, directly on your local device.

Each signed document comes with a detailed log of transactions (signer data, signature time stamps, IP addresses, etc.) attached. Which ultimately makes electronic signatures more accountable than traditional ink signatures. Learn more about the Audit Trail.
