Is It Legal to Sign Documents Electronically?

August 20, 2025

In a world of digital contracts and remote work, the electronic signature has become a cornerstone of business. But a common question arises: is signing a document online with a tool like Docento.app actually legally binding?

The short answer is yes. In most parts of the world, electronic signatures carry the same legal weight as a traditional "wet ink" signature, thanks to specific laws enacted to govern them.

The Laws That Make E-Signatures Legal

In the United States, two key pieces of legislation establish the legality of electronic signatures:

  1. The Electronic Signatures in Global and National Commerce (ESIGN) Act (2000): This federal law states that a contract or signature "may not be denied legal effect, validity, or enforceability solely because it is in electronic form."
  2. The Uniform Electronic Transactions Act (UETA): This has been adopted by 49 states (all except New York, which has its own similar law). UETA provides a legal framework for the use of electronic signatures and records in state commerce.

Most other industrialized nations, including the European Union (with its eIDAS regulation), Canada, and Australia, have similar laws that recognize the validity of electronic signatures.

What Makes an Electronic Signature Valid?

For an e-signature to be considered legally binding, it generally needs to meet a few key requirements:

  • Intent to Sign: The signer must clearly understand that they are applying a signature and intend for it to be their legally binding mark. Clicking a button that says "Accept" or "Sign" is usually sufficient.
  • Consent to Do Business Electronically: The parties involved must agree to conduct the transaction electronically.
  • Clear Attribution: The signature must be linked to the person signing it. This can be through an email trail, an account login, or other identifying information.
  • Record Integrity: The signed document must be saved in a way that retains its integrity and can be accurately reproduced for all parties.

How Does Docento.app Fit In?

When you sign a PDF online with a tool like Docento.app, you are creating a valid electronic signature.

  • You demonstrate intent by using the signature tool and placing it on the document.
  • The act of emailing and opening the document implies consent.
  • The final, saved PDF serves as the record.

While some platforms offer complex audit trails for high-value transactions, for the vast majority of everyday agreements—like service contracts, NDAs, and onboarding forms—a simple, user-applied electronic signature is perfectly sufficient and legally sound.

So, the next time you need to sign a document, you can do so with confidence, knowing that your electronic signature is backed by law.
