A prospective customer wants to talk numbers tomorrow but needs an NDA signed first. You email the PDF, they print it, sign it, scan it badly, email it back at 11pm. You return the favour. The whole thing takes twenty hours when it could take twenty minutes.
Electronic signing on NDAs is the lowest-hanging fruit in commercial workflow. There's almost no reason not to.
Prepare the NDA properly
Start with a clean PDF, either exported from Word via Word to PDF or built from your firm's template. Make sure the signing block has clear fields for each party: name, title, signature, date. If you're using a mutual NDA, ensure both parties have equivalent signing blocks — don't ask the counterparty to sign in a margin while you have a proper line.
Send for signature
Use sign PDF to drop signature fields onto the NDA and send a signing link to the counterparty. They sign in their browser, no account required. You receive the signed file and audit certificate as soon as they're done. For a mutual NDA, you sign too — order doesn't usually matter for NDAs.
Capture the audit trail
The audit certificate is the difference between a defensible signature and a typed name. It records who signed, when, from what IP, and which fields they completed. Save it alongside the signed PDF. If the NDA is ever invoked — to chase a breach, for example — the audit trail is your evidence the counterparty signed knowingly.
Same-day close
Most NDAs close within an hour of being sent if both parties are at their desks. The bottleneck is usually internal approvals on your side, not the signing tool. Have your standard NDA pre-approved and ready to go, customise the counterparty's details, send, sign, done. The numbers conversation happens the same afternoon.
FAQ
Is an electronically signed NDA enforceable?
In both the UK and US, yes — NDAs are commercial contracts and fall squarely within electronic signature statutes. The audit trail strengthens enforceability further.
Should I use a mutual or one-way NDA?
Mutual if both parties are sharing confidential information, one-way if only one is. Mutual is more common for early-stage commercial discussions.
What if the counterparty refuses to e-sign?
Rare in 2026 but it happens. Offer to print, sign, scan on their side and accept the scanned signature with their typed name beside it. The audit trail is weaker but still defensible.
Do I need a witness for an NDA?
No — NDAs are simple contracts and don't require witnessing in the UK or US for standard commercial use.
