Two-Party Signing

Both Parties Sign in One Seamless Flow

Set up the MNDA once — both parties receive signing links and can sign simultaneously or sequentially. Both get the countersigned copy automatically when all parties have executed.

  • Parallel signing — Both parties receive signing invitations simultaneously.
  • Sequential option — Party A signs first, then Party B is notified — for formal execution.
  • Countersigned delivery — Both parties receive the fully executed MNDA automatically.

NDA Protection

Confidentiality Protection You Can Enforce

An MNDA is only as strong as its evidence of execution. Zignature's audit trail shows exactly when each party reviewed and signed — critical evidence in any confidentiality breach proceeding.

  • Review evidence — Timestamp of when each party opened and read the document.
  • Signature evidence — Exact time, IP address, and device for each party's signature.
  • Cryptographic seal — Any post-signing document modification is immediately detectable.

Confidentiality Protection You Can Enforce

Court-admissible execution evidence with timestamp and IP capture for enforceability.

Frequently Asked Questions

Everything you need to know.

What is a mutual NDA and how is it different from a standard NDA?

A mutual NDA (MNDA) creates confidentiality obligations on both parties — both must protect information shared by the other. A standard (unilateral) NDA only obligates the receiving party. MNDAs are used when both parties are sharing confidential information.

Can both parties sign an MNDA simultaneously with Zignature?

Yes. Configure parallel signing in Zignature — both parties receive signing invitations simultaneously and can sign at any time without waiting for the other party. Both receive the countersigned copy when execution is complete.

What provisions should a mutual NDA include?

A balanced MNDA should cover: definition of confidential information, obligations of each party, permitted disclosures (legal obligation, professional advisors), exclusions (public information, independent development), term duration, survival of obligations, and governing law.

Can I use Zignature MNDAs for M&A due diligence discussions?

Yes. M&A NDAs are one of the most common use cases for mutual NDAs. Include deal-specific provisions like standstill obligations, no-hire restrictions, and return-of-information requirements in your M&A MNDA template.

How long should an MNDA term be?

NDA terms typically range from 1 to 5 years, depending on the industry and nature of information. Technology companies often use 2-3 year terms; M&A NDAs often have shorter terms (1-2 years) for the negotiation period.

Are electronically signed MNDAs enforceable against both parties?

Yes. Zignature's audit trail captures signing evidence for both parties — IP address, timestamp, and cryptographic document seal. This creates enforcement-ready evidence for each party in any confidentiality breach proceeding.
