Legal + Trusted + Secure Signatures

In the digital age, electronic signatures have become a cornerstone of efficient business transactions. But what makes an e-signature legally binding? And how do you ensure trust and security in a digital agreement? 

To answer these questions, we need to explore the frameworks of the E-SIGN Act and the Uniform Electronic Transactions Act (UETA) and dive into the nuances between electronic signatures and digital signatures.

The Four Pillars of E-Signature Legality

Under the E-SIGN Act and UETA, an electronic signature is legally recognized if it meets these four key criteria:

1. Intent to Sign
   An e-signature is only valid if the signer demonstrates a clear intention to agree to the document’s terms, just as with traditional ink signatures.
   
   
2. Consent to Use Electronic Records
   The parties must agree to conduct the transaction electronically. For consumers, additional steps are required:some text
   1. They must receive clear disclosures about their rights under electronic transactions.
   2. They must affirmatively agree to use electronic records.
   3. They must retain the option to withdraw consent without penalty.
      
      
3. Attribution and Association of Signature with the Document
   The electronic system used must connect the signature to the signed document. This can include timestamps, audit trails, or visual indicators that the signature was electronically applied.
   
   
4. Record Retention
   E-signature records must be stored securely and remain accessible for all parties, ensuring they can be accurately reproduced when needed.

But meeting these criteria is only the beginning. To truly ensure enforceability, trust, and security, the way you implement electronic signatures matters.

Legally Binding vs. Trust vs Security

At its core, making an agreement legally binding doesn’t require much—sometimes, even a handshake will do. Ever heard of a verbal contract? Those are legal! 

However, legal enforceability doesn’t always mean the agreement will hold up in court. That’s where trust and security come into play.

1. Handshake Agreements: Still Legal

Remember that a handshake or verbal agreements are legally binding. But think about it this way:

• Legally Binding: Yes
• Trust Factor: Who do you trust? Who said what? If there’s no record, who do you believe?
• Security Risks: There’s nothing secure about a handshake or verbal agreement, so someone can “change the terms” just by remembering it differently than you did

2. Simple Electronic Signatures: Basic but Vulnerable

A scanned PDF of a wet signature or a digital image of your signature pasted onto a document is an example of a Simple Electronic Signature.

• Legally Binding: Yes
• Trust Factor: A timestamp in the email can demonstrate when the document was signed
• Security Risks: These PDFs can often be edited, leaving the signature and the terms of the contract vulnerable to tampering.

While this method may work in informal situations, it lacks the robust trust and security needed for critical agreements.

3. Electronic Signatures with Cryptography

To elevate trust and security, organizations can use cryptographically signed PDFs. Trust authorities like Entrust or DigiCert issue certificates, such as Document Signing Certificates, that:

• Lock the PDF: Cryptographically sign and seal the document, making it tamper-proof
• Verify Authenticity: Provide a hash of the document for validation against tampering
• Add a Timestamp: From a trusted Time Stamp Authority, proving when the document was signed
• Enable Tracking: Audit trails can include IP addresses, geolocation data, and timestamps for extra layers of verification

These methods are still classified as Simple Electronic Signatures but offer significantly enhanced security features, making them more trustworthy and enforceable. This is what you are buying from most e-sign companies on the market.

Organization Validation (OV) by a Trust Authority

Organization Validation (OV) is a process where a trusted certificate authority (CA) verifies the identity and legitimacy of an organization before issuing a Document Signing Certificate, just as they do with SSL/TLS certs. This certificate proves to signers that a company is a real, verified business. The CA checks official documents, like business registration or legal status, to ensure authenticity. OV certificates not only encrypt the document but also add a layer of trust by displaying the organization's name in the certificate, reassuring signers that the document is secure and trustworthy.

Wait? I didn’t get a cert when I signed with Big eSign!

We know! Open up Adobe Acrobat or similar and you’ll see a big green check that says your signatures are valid. This is great, because it means the cryptography is applied. However, look under the hood and open up the signature panel. What do you see?

You’ll see the cert is the Big eSign company and not you. 

4. Buy Your Own OV Cert

With UnicornForms, we are the only e-sign provider that will sell you your own Organization Validation (OV) cert for your document signatures. This provides the highest form of trust for your customers.

We offer this to plans that need 5,000 signatures or more because it tends to be more common in high volume contexts.

5. Digital Signatures: The Gold Standard

For the highest level of security and trust, Digital Signatures (sometimes called Advanced Electronic Signatures) are used. These require:

• Individual Validation (IV): Personal identity verification through a Trust Authority, often in-person or via live video with a driver’s license
• Special Hardware: A USB token device that securely stores your cryptographic key
• Unmatched Security: Digital Signatures are tamper-proof, tied directly to the signer, and offer the most robust protection against fraud

While common in Europe due to stricter regulations, Digital Signatures are less popular in the U.S. because they require specialized hardware and a more complex setup.

Why E-Sign Platforms Dominate

For most users, convenience outweighs complexity:

• Ease of Use: Accessible from mobile devices and integrated into workflows
• Streamlined Security: They rent their own Document Signing Certificates, saving businesses from the hassle of purchasing and managing their own certificates

The Trade-Off: While these platforms simplify the process, they technically reduce the trust element at a granular level. Instead of the document being cryptographically signed under your company or name, it’s signed under the platform’s certificate, as seen in the "Signature Panel" of a PDF.

Balancing Trust, Security, and Convenience

Whether you choose a Simple Electronic Signature, an enhanced Electronic Signature, or a full-fledged Digital Signature depends on the transaction’s stakes and your need for trust and security.

• For low-risk agreements, a Simple Electronic Signature may suffice
• For critical business transactions, enhanced Electronic Signatures add a layer of protection
• For highly sensitive or regulated agreements, Digital Signatures offer unparalleled security and trust

By understanding the nuances of e-signature legality and security, you can confidently choose the right solution for your needs while ensuring your agreements remain trustworthy, secure, and legally binding.
