Are electronic signatures legally binding?

In most countries, yes, for most business agreements. The US ESIGN Act and UETA, the EU's eIDAS regulation and India's IT Act 2000 all recognise electronic signatures, so a contract can't be refused just because it was signed electronically. There are exceptions, such as wills and some property and court documents, and some laws ask for a stronger, certificate-based signature. This is general information, not legal advice.

What does US law say about electronic signatures?

The federal ESIGN Act (2000) says a signature or contract can't be denied legal effect just because it is electronic. Almost every state has adopted the Uniform Electronic Transactions Act (UETA), and New York has its own similar law. Both rely on the parties agreeing to do business electronically, and ESIGN adds disclosure and consent rules when consumers receive legally required information electronically.

ESIGN excludes some documents, including wills and testamentary trusts, many family-law matters such as adoption and divorce, court orders and notices, and certain notices such as cancelling utilities or foreclosure on a primary home.

What does eIDAS say in the EU?

eIDAS defines three levels: simple, advanced and qualified electronic signatures. A court may not refuse an electronic signature as evidence only because it is electronic, so a simple signature is recognised. A qualified electronic signature has the same legal effect as a handwritten one across the EU, and national law sometimes requires a qualified or advanced signature for particular documents.

What does India's IT Act 2000 say?

The Information Technology Act 2000 recognises electronic records and contracts formed electronically. It gives electronic signatures special legal status when they use a technique listed in the Act, currently digital signature certificates and Aadhaar-based eSign. The Act doesn't apply to negotiable instruments other than cheques, powers of attorney, trusts, wills, and contracts for the sale or conveyance of immovable property.

Many businesses use simple e-signatures for ordinary commercial agreements, relying on the audit trail as evidence. Where a law, regulator or counterparty expects a DSC or Aadhaar eSign, use one.

What evidence helps an e-signature hold up?

  • Each signer's consent to sign electronically, recorded before they start.
  • Who the link went to, and when it was opened and signed, with IP addresses.
  • A clear action to sign, not a pre-ticked box.
  • A copy of the signed document for every party.
  • A certificate or log that ties these together.

What does Flaxxa Sign record?

Flaxxa Sign records each signer's consent to sign electronically, every step with its time, IP address and browser, and how they signed (drawn, typed or uploaded). Everyone receives the finished PDF, and the sender can download a signing certificate with the recipients, times, IP addresses, the event timeline and SHA-256 hashes of the original document and signature images.

These are simple electronic signatures. Flaxxa Sign doesn't offer advanced or qualified signatures under eIDAS, or digital signature certificates or Aadhaar eSign under India's IT Act, and it doesn't verify a signer's identity beyond the email link.

Frequently asked questions

Generally yes, in the US, the EU, the UK and India, for documents not excluded by law. How much weight it carries depends on the evidence, which is why an audit trail and consent record matter.
