What is the difference between an electronic signature and a digital signature?

Feature Electronic Signature Digital Signature. Proof Level Shows intent, limited proof Strong proof, non-repudiation Technology Simple electronic mark PKI-backed technology

What are the different levels of e-signatures under EU eIDAS law?

Simple Electronic Signature: Basic level, shows intent. Advanced Electronic Signature (AdES): Linked uniquely to the signer, able to identify the signer, created using data the signer can control, and detects any later changes. Qualified Electronic Signature (QES): The highest level, legally equivalent to a handwritten signature, requires a qualified certificate and secure signature creation device.

If I need to use an e-signature in court, what should I do to prepare?

First, make sure the e-signature used meets the legal requirements of your country (e.g., ESIGN Act in the US, eIDAS in the EU). Choose a signature level that provides strong proof, like a digital signature or a Qualified Electronic Signature (QES) if in the EU. Ensure the audit trail or Certificate of Completion is generated and kept with the signed PDF. This document contains all the necessary evidence. If using Acrobat Sign, configure it to attach the audit report to emails and downloads for easy access and safekeeping.

Acrobat Sign helps ensure legal validity by creating a detailed audit trail. This trail records important details like the signer's IP address, device, timestamps, and cryptographic hashes. This information acts as court-ready evidence, proving the signature's authenticity and integrity. Acrobat Sign also supports different signature levels, including those compliant with EU eIDAS regulations like QES, which is legally equal to a wet signature.

An audit trail is important because it provides strong legal proof for your e-signatures. It records all the steps of the signing process, including who signed, when, and from what device. If there is ever a dispute or legal challenge, this detailed report, also called a Certificate of Completion, serves as court-ready evidence to confirm the signature's validity.
