With the rise of digital transformation, signing contracts and agreements no longer requires printing, scanning, or mailing. Digital signatures have emerged as a secure, fast, and legally recognized way to sign documents online. But are they truly valid under the law?
At Sign Well, we help users create secure and professional digital signatures. In this blog, we’ll explore the legal framework around digital signatures, their enforceability in contracts, and how they compare with traditional handwritten signatures.
What Is a Digital Signature?
A digital signature is a type of electronic signature that uses cryptographic techniques to verify the identity of the signer and ensure the document has not been altered. It typically involves:
A digital certificate issued by a Certificate Authority (CA)
Public and private key encryption
A unique digital fingerprint tied to the document
This level of security makes digital signatures especially suitable for legal and high-value documents.
How Digital Signatures Work
Document Creation – The sender prepares a digital document.
Signing – The sender uses their private key to generate a unique signature.
Transmission – The signed document is sent to the recipient.
Verification – The recipient uses the sender’s public key to verify the signature and ensure the document was not modified.
This cryptographic process ensures both integrity and authentication.
Legal Recognition of Digital Signatures
United States
The Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA) grant digital signatures the same legal standing as handwritten ones.
Key points:
Must show intent to sign
Parties must consent to electronic transactions
Signature must be attributable to the person
European Union
Governed by the eIDAS Regulation (Electronic Identification, Authentication and Trust Services):
Defines three types of e-signatures: simple, advanced, and qualified
Qualified electronic signatures (QES) are legally equivalent to handwritten signatures
Other Countries
Canada: Recognized under the PIPEDA Act
India: Valid under the Information Technology Act, 2000
Australia: Covered by the Electronic Transactions Act 1999
Most countries now legally recognize digital signatures if basic conditions of consent and authentication are met.
Digital Signatures vs Electronic Signatures
| Feature | Digital Signature | Electronic Signature |
|---|---|---|
| Technology | Uses encryption and certificates | May involve typing, clicking, or drawing |
| Security | High (cryptographically secure) | Moderate |
| Legal Weight | Strong (especially in QES format) | Varies by region and platform |
| Use Cases | Legal, financial, government docs | General business, forms, approvals |
Digital signatures are more secure and carry higher legal weight due to encryption and verification protocols.
Why Digital Signatures Are Legally Trusted
1. Authentication
The signer’s identity can be confirmed using their digital certificate.
2. Non-repudiation
The signer cannot deny the validity of the signature because it is tied to their private key.
3. Integrity
Any changes made to the document after signing are detectable.
4. Audit Trails
Many digital signature solutions include timestamps and logs that serve as legal evidence.
Types of Contracts Supported
Digital signatures are commonly used in:
Employment contracts
Vendor and client agreements
Lease and rental agreements
Sales contracts
NDAs and confidentiality agreements
Government tenders
However, documents like wills, birth certificates, and court orders may still require handwritten signatures depending on the jurisdiction.
What Courts Look for in a Legal Signature
To determine validity, courts generally check:
Was the signature applied by the person named?
Was there a clear intent to sign?
Was the process secure and reliable?
Was the document altered post-signature?
Digital signatures fulfill all these criteria when implemented correctly.
