The short answer is yes—in most countries, e-signatures are considered legally valid as handwritten ones when they meet specific legal requirements.
The short answer is yes—in most countries, e-signatures are considered legally valid as handwritten ones when they meet specific legal requirements.
However, not all e-signatures are created equal, and understanding their legal framework is key to ensuring compliance.
Here's why you can trust e-signatures, how they work, and how to use Smallpdf to streamline the process.
What Makes an E-signature Legally Binding?
For an e-signature to be legally binding, it must meet certain criteria outlined by regulations such as the ESIGN Act (Electronic Signatures in Global and National Commerce Act) in the United States, or eIDAS (Electronic Identification, Authentication, and Trust Services) in the European Union.
Here are the key legal requirements to watch for:
- Intent to Sign: The signer must clearly understand and agree that their action (e.g., typing their name, drawing their signature) serves as a valid signature.
- Consent to Do Business Electronically: Both parties must agree to conduct the transaction electronically. For instance, a checkbox acknowledging consent fulfills this requirement.
- Authentication of the Signer: There must be a process to verify the identity of the signer, such as email verification or multi-factor authentication.
- Association with the Record: The signature must be linked to the signed document, ensuring that records can’t be tampered with.
- Record Retention: Signed documents must be stored safely and be easily retrievable if needed for legal purposes.
With Smallpdf, these criteria are baked into our Sign PDF and Request Signatures workflows, ensuring your documents are legally valid in the U.S., EU, and beyond.
How E-signatures Work in Practice
E-signatures are recognized because they demonstrate a clear intent to sign and are secured through processes that make forgery or tampering difficult. Here’s a breakdown of how you can use Smallpdf to create legal e-signatures seamlessly.
