Common Misconceptions

"E-signatures aren't legally binding"

False. E-signatures have been legally valid in the U.S. since 2000 (ESIGN Act) and are recognized in most countries worldwide.

"I need special software to sign electronically"

False. While dedicated platforms offer benefits, you can create basic e-signatures with free tools like Preview (Mac), Adobe Reader, or even typing your name.

"E-signatures are easy to forge"

Partially false. Modern e-signature platforms provide better security than paper signatures through audit trails, encryption, and authentication. Signature forgery is actually easier with paper.

"All documents can be signed electronically"

Mostly true, with exceptions. Most business and personal documents can be e-signed. Exceptions include wills (most states), certain court documents, and some government forms.

Frequently Asked Questions

Is an electronic signature the same as a digital signature?

No. An electronic signature is any electronic indication of agreement. A digital signature is a specific type that uses cryptographic technology for enhanced security. All digital signatures are electronic signatures, but not all electronic signatures are digital.

Can I use a picture of my signature?

Yes. Uploading an image of your handwritten signature is a valid form of electronic signature. Many platforms allow you to upload, type, or draw your signature.

Do electronic signatures hold up in court?

Yes. E-signatures are regularly upheld in court. The audit trail provided by e-signature platforms often provides stronger evidence than paper signatures. Courts have enforced e-signed contracts in countless cases.

What if the other party doesn't accept e-signatures?

You can offer alternatives:

• Provide wet signature option
• Explain legal validity
• Use more advanced signature types
• Check if their concern is policy vs. legal

How do I verify an electronic signature?

E-signature platforms provide verification through:

• Audit trail review
• Certificate of completion
