In today's fast-paced digital world, the friction of printing, signing, scanning, and mailing documents feels like a relic from a bygone era.
It's a bottleneck that slows down deals, delays projects, and creates unnecessary administrative burdens. If you've ever missed a deadline waiting for a 'wet signature,' you understand the pain.
Enter the electronic signature (or e-signature). It's more than just a digital version of your handwritten sign-off; it's a transformative technology that streamlines workflows, enhances security, and accelerates the speed of business.
This guide will demystify electronic signatures, explaining exactly what they are, how they work, and why they are a critical tool for any modern business.
Key Takeaways
- Definition: An electronic signature is a legally recognized way to consent to an agreement electronically.
It can be as simple as a typed name, an uploaded image of a signature, or a symbol.
- Legality: E-signatures are legally binding in most developed countries, thanks to laws like the ESIGN Act in the United States and the eIDAS regulation in the European Union.
- Security: Modern e-signature platforms like eSignly provide robust security, including encryption and a detailed audit trail that tracks every action taken on a document, making them often more secure than paper-based methods.
- How to Use: The process is simple: upload a document, add fields for signers, send it via email, and receive a notification once it's signed. The platform handles the security and legal record-keeping.
What Exactly is an Electronic Signature? (The Simple Definition)
At its core, an electronic signature is a symbol or process attached to a contract or record, executed by a person with the intent to sign.
It's the digital equivalent of a handwritten signature. This could be a name typed at the bottom of an email, a scanned image of a signature, or a signature drawn on a screen with a finger or stylus.
The key is not the image itself, but the verifiable process and intent behind it. A secure e-signature solution captures this intent and creates a tamper-evident record of the entire signing process.
Electronic Signature vs. Digital Signature: What's the Difference?
While often used interchangeably, 'electronic signature' and 'digital signature' have distinct technical meanings.
Think of it this way: all digital signatures are electronic signatures, but not all electronic signatures are digital signatures.
- Electronic Signature: This is a broad, legally-defined term focused on the signer's intent. It's technology-neutral.
- Digital Signature: This is a specific type of electronic signature that uses advanced encryption (public-key infrastructure or PKI) to secure a document. It creates a unique digital 'fingerprint.' If the document is altered after signing, the digital signature is invalidated.
For most business use cases, a robust electronic signature solution from a provider like eSignly, which includes strong security and audit trails, offers the perfect blend of security and ease of use.
Electronic Signature vs. Wet Signature: The Modern Handshake
A 'wet signature' is the traditional, pen-on-paper signature. For centuries, it was the only way to execute a contract.
However, it's slow, inefficient, and difficult to verify without an expert. Electronic signatures solve these problems by creating an instant, verifiable, and secure method of agreement that works across any distance.
Are Electronic Signatures Legal and Binding?
This is the most common and critical question, and the answer is a resounding yes. The legal validity of electronic signatures is well-established globally, providing the same legal standing as their handwritten counterparts.
Key Legislation You Should Know
Several landmark laws form the foundation of e-signature legality:
- The ESIGN Act (2000): In the United States, the Electronic Signatures in Global and National Commerce Act ensures that electronic signatures and records are legally valid and cannot be denied legal effect simply because they are electronic. This federal law makes e-signatures enforceable in all 50 states. You can read more about it from sources like Adobe's guide on the ESIGN Act.
- The UETA Act (1999): The Uniform Electronic Transactions Act was adopted by 49 states and provides a legal framework for the use of electronic signatures at the state level, harmonizing with the ESIGN Act.
- eIDAS Regulation: In the European Union, the Electronic Identification, Authentication and Trust Services regulation provides a consistent legal framework for electronic signatures across all member states, making cross-border business easier and more secure.

The Three Pillars of a Legally Binding E-Signature
For an e-signature to be considered legally binding, it generally needs to satisfy three conditions:
- Intent to Sign: The signer must demonstrate a clear intention to sign the document, just as they would with a pen. Clicking a button that says 'I agree' or drawing a signature fulfills this.
- Consent to do Business Electronically: All parties involved must agree to use electronic methods to conduct the transaction.
- Record and Retention: The signature and the final document must be recorded and stored in a way that ensures integrity. A comprehensive audit trail, which tracks every action from sending to signing, is crucial here.

Frequently Asked Questions
What types of documents can I sign with an electronic signature?
You can use electronic signatures for a wide variety of documents, including sales contracts, non-disclosure agreements (NDAs), new hire paperwork, vendor agreements, real estate contracts, financial loan documents, and patient consent forms.
However, some specific documents, like wills or court orders, may still require a physical signature depending on local laws.
Do my clients or customers need to install software to sign a document?
No. With a platform like eSignly, the person signing the document does not need to download any software or create an account.
They simply receive an email with a secure link, which they can open in any web browser on any device (computer, tablet, or phone) to review and sign the document.
How can I be sure who is signing the document?
Secure e-signature platforms use multiple methods for authentication. The most basic is email verification, as the signing link is sent to a specific email address.
For higher-security needs, providers can offer multi-factor authentication (MFA), such as sending a one-time passcode to the signer's mobile phone, to add an extra layer of identity verification.
What is an audit trail and why is it important?
An audit trail is a detailed, time-stamped record of every event that occurs during the signing process. It captures who sent the document, who viewed it, when and where they signed (including their IP address), and more.
This comprehensive log is attached to the final signed document and serves as powerful, court-admissible evidence of the signature's validity and the document's integrity.
