An electronic signature (eSignature) is a legally binding signature applied electronically, either via a signing platform (DocuSign, Adobe Sign) or through more advanced qualified electronic signatures. eSignature has replaced ink for most business contracts in most jurisdictions.
Types of electronic signatures
Simple electronic signatures (email confirmation, click-to-sign), advanced electronic signatures (with authentication), and qualified electronic signatures under eIDAS (highest legal standing). Choice depends on jurisdiction and document type.
Legal framework
In the EU: eIDAS Regulation governs electronic signatures. In the US: ESIGN Act and UETA. In practice, standard commercial contracts execute reliably via major platforms without needing qualified signatures.
