Decide: Mutual or Unilateral

Unilateral NDA — One party shares confidential info, the other receives. Common for vendor pitches, employee onboarding. Mutual NDA — Both parties share confidential info. Common for partnership discussions, M&A. Most modern relationships call for mutual NDAs even when one side starts as 'just listening.'

Define 'Confidential Information' Specifically

Vague definitions get NDAs thrown out. Include: business plans, customer lists, financial data, source code, designs, processes — and exclude: publicly available info, info known before disclosure, info independently developed, and info legally required to disclose.

Set the Term

How long does confidentiality last? Standard: 2-5 years for general business info, perpetual for trade secrets and PII. Shorter terms (1-2 years) are normal for vendor pitches.

Add Required Exceptions

All NDAs need carve-outs for:

Specify Remedies

Damages alone often inadequate for confidentiality breaches. Include right to seek injunctive relief, attorney fees, and (for serious cases) liquidated damages.

FAQ

Are NDAs really enforceable?

Yes, well-drafted NDAs are routinely enforced. But poorly drafted ones (vague scope, unreasonable duration, no exceptions) get tossed. Use AI templates with proven enforceable language.

Can I make someone sign an NDA before a meeting?

Yes. It's standard for sensitive discussions. Send the NDA at least 24 hours in advance so they can review (or have counsel review).

Can I include penalties for breaching the NDA?

Liquidated damages clauses are enforceable if the amount is reasonable and tied to actual harm. Excessive penalties may be voided. $5K-$50K per breach is common for small business NDAs.
