Are electronic signatures legally binding?
In most of the world, yes. Laws in the United States, the European Union, India and many other countries say that a signature or a contract can’t be refused legal effect simply because it is electronic. An agreement signed on screen can be as binding as one signed on paper.
What those laws don’t do is make every electronic mark automatically valid. A signature still has to show that a particular person meant to agree to a particular document. On paper, that proof is the signature itself plus whatever witnesses or copies happen to exist. Electronically, it is the record of the signing — and that record can be far more complete than paper ever was.
Not legal advice
This page explains the general principles. Rules vary by country, state and document type, so check the requirements that apply to your agreement and take legal advice where the stakes are high.
What makes an e-signature hold up
Although the wording differs from one law to the next, the same four ideas come up again and again. Here is each one, and how SignPe records it.
| Principle | What it means | How SignPe captures it |
|---|---|---|
| Intent to sign | The signer deliberately chose to sign | Signers place their own signature in the fields assigned to them, and can decline instead |
| Consent to electronic records | The signer agreed to do business electronically | Guest signers accept an electronic-records consent screen before signing |
| Attribution | The signature can be linked to a specific person | Each request goes to the signer’s own email; registered users sign in first; Aadhaar eSign adds OTP verification in India |
| Record integrity | The signed document is kept intact and can be reproduced | The signed copy is stored, emailed to everyone and accompanied by an audit trail |
Intent is why the signing page asks each signer to act on their own fields, and why “Decline to sign?” is always an option — a signature someone could not refuse is weaker evidence than one they chose to give. Consent is why guests see the consent screen first. Attribution is why the link reaches the signer’s own inbox rather than a shared one. And integrity is why the finished document is kept exactly as signed.
The audit trail: your evidence file
Every action on a SignPe document is recorded with its date and time — sent, received, opened, saved, signed, declined or voided. On the web you can follow it in the Activity timeline in the document’s info drawer; in the mobile app it’s the Document History page.
When you need to show the record to someone else, download the audit trail PDF. It includes:
- The document ID, which ties the audit trail to one specific document.
- The sent date and the completed date.
- For each signer: when they were emailed, when they viewed the document and when they signed.
This is what the homepage means by a court-admissible audit trail: a time-stamped account of the signing that you can produce if an agreement is ever questioned. Whether evidence is admitted, and how much weight it carries, is always for the court or tribunal to decide — but a dated record of who received, opened and signed a document is the kind of evidence a wet signature on its own can’t give you.
Voided documents keep their history too. A void is logged in the audit trail next to everything that came before it, so a withdrawn request is never silently erased. See void documents.
The laws that recognise e-signatures
- United States — the ESIGN Act and UETA. The federal ESIGN Act and the Uniform Electronic Transactions Act, adopted by most states, give electronic signatures and records the same legal standing as paper ones.
- European Union — eIDAS. The eIDAS regulation says an electronic signature can’t be denied legal effect or admissibility as evidence solely because it is electronic, and recognises different levels of electronic signature.
- India — the IT Act 2000. The Information Technology Act recognises electronic signatures and electronic records, and the Indian Contract Act 1872 governs whether the agreement itself is valid. Aadhaar eSign is one of the electronic signature methods the IT Act framework recognises.
For a closer look at Indian law, read the legality guide. For other countries, the global e-signature laws article is a good starting point.
Some documents are usually excluded
Most e-signature laws carve out certain documents — commonly wills, some property deeds and transfers, and court orders or official notices. Check your local rules and the legality guide before signing these electronically.
Aadhaar eSign for stronger identity in India
For agreements in India where you want more than an email link as proof of identity, SignPe offers Aadhaar eSign. The signer verifies with an OTP through eMudhra, and the result is a PKI-signed PDF that carries a SHA-256 hash of the document and an evidence certificate.
The hash matters for integrity: it is a fingerprint of the exact document that was signed, so any later change to the file no longer matches it. That makes an Aadhaar-signed PDF independently verifiable, long after the signing itself.
Reliable: the record is stored, retrievable and identical
A legally binding signature is only useful if you can still find it years later. SignPe treats reliability as three plain promises:
- Stored. Documents are kept in encrypted cloud object storage, not in an inbox or on one laptop.
- Retrievable. Every completed agreement is in your Documents list under the Signed filter, on the web and in the iPhone and Android apps — one account, synced across every device.
- Identical. When the last signer signs, everyone on the document is emailed the same signed copy at the same moment, so there is no “which version did you sign?” afterwards.
Security sits underneath all three. Connections run over HTTPS/TLS, and only the people on a document — the sender, its signers and observers — can open it. The full detail is on e-signature security.
Best practices for signatures that stand up
- Use each signer’s own email address. A shared mailbox weakens attribution.
- Assign every field to the right signer. It makes clear who agreed to what.
- Don’t edit and resend an old request. If something changes, void the document and send a fresh one with its own audit trail.
- Download the audit trail PDF for important agreements and keep it with your records.
- Use Aadhaar eSign for Indian agreements where identity is likely to be disputed.
- Check the exclusions before signing wills, deeds or other documents your local law treats differently.
