Is an Electronic Signature on an NDA Legally Valid?

Yes — in the United States, electronic signatures are legally binding on NDAs and most contracts under the ESIGN Act (2000) and the UETA. The EU has the eIDAS regulation. India has the IT Act Section 5. In simple terms: if both parties agree electronically, it holds up in court. Major companies including Google, Amazon, and Apple accept and enforce e-signed NDAs daily.

Step-by-Step: Sign Your NDA in 60 Seconds

1.

Open the Sign PDF tool

Go to GenZDoc's Sign PDF tool. No account, no download, completely free.

2.

Upload your NDA PDF

Drag and drop the NDA file from your Downloads folder or wherever it was saved.

3.

Create your signature

Draw your real signature using your mouse or finger on a touchscreen, type it in a handwriting font, or upload an image of your handwritten signature.

4.

Place the signature on the document

Drag your signature to the correct signature line. Resize it to match the space provided.

5.

Download and send

Click Download. Attach the signed PDF to your email reply. Done — no printing, no scanning, no notary visit.

What NOT to Do

  • Don't screenshot your signature: A screenshot of your signature pasted into an email body is not legally sufficient evidence of agreement.
  • Don't use a photo of a signed page: A JPEG photo of a handwritten signature is low quality, hard to verify, and most legal systems prefer a digitally signed PDF on record.
  • Don't sign with a pen tool in Word: Word drawing tools do not create a legally verifiable electronic signature record — use a dedicated e-signature PDF tool.

Already Signed? Protect It Before Sending

After signing your NDA, consider adding password protection before emailing it. This prevents the recipient from editing the PDF or removing your signature.
