Digital Signature for Contracts

Digital Signature vs. Electronic Signature: What's the Difference?

The terms are often used interchangeably, but there is a technical distinction. An electronic signature is any digital representation of a person's intent to sign — it can be as simple as a typed name. A digital signature uses cryptographic technology (typically PKI — Public Key Infrastructure) to create a unique mathematical fingerprint of the document at the time of signing. If the document is altered after signing, the digital signature becomes invalid. Signova uses both approaches: a visible electronic signature for the signer's name, and a cryptographic hash of the document to detect any post-signing alterations.

Why Contracts Need Digital Signatures

Unsigned contracts are unenforceable. A contract without signatures is merely a proposal. Once both parties have signed, the contract becomes a binding legal agreement. Digital signatures accelerate this process by eliminating the need to print, mail, or physically exchange documents. For businesses operating across different cities, states, or countries, digital signatures are not just convenient — they are essential for operational efficiency.

Which Contracts Require Digital Signatures?

Any contract that would otherwise require a wet signature can be signed digitally. This includes: non-disclosure agreements, independent contractor agreements, service agreements, employment contracts, lease agreements, consulting agreements, software licensing agreements, and partnership agreements. The only exceptions are documents that specifically require notarization or witnesses under applicable law.

Frequently Asked Questions

Can a digital signature be forged?

A properly implemented digital signature using cryptographic hashing is extremely difficult to forge. Signova's audit trail captures the signer's IP address, email, and timestamp, making fraudulent signatures easily detectable.

Do I need special software to add a digital signature to a contract?

No. Signova works entirely in your browser. No software installation or plugin is required.

Can I add a digital signature to a contract I received by email?

Yes. Download the contract, upload it to Signova, add your signature, and send the signed copy back to the sender.
