NDA for Joint Ventures UK: Protecting Both Parties in a JV

Why every UK joint venture starts with an NDA

A joint venture requires both prospective partners to make themselves commercially vulnerable before they know whether the arrangement will work. Financial projections, customer relationships, proprietary technology and operational know-how must all be shared so each side can evaluate the opportunity — yet the JV may never proceed.

Without a signed NDA, each party relies on equitable confidence (Coco v AN Clark [1969]) and implied contractual terms, which are costly to enforce and presuppose that the information already has a recognised quality of confidence. A written NDA creates a clear, dated record of the disclosure, what obligations attach to it, and what remedies are available if those obligations are breached.

Key clauses a JV NDA must include

• Definition of confidential information — broad enough to cover all material exchanged in due diligence: written, oral, electronic, visual, and derivative analyses.
• Purpose limitation — the receiving party may use confidential information only for evaluating or pursuing the proposed joint venture, not for any other commercial purpose.
• No IP licence or transfer — disclosure of technology, know-how or proprietary processes confers no intellectual property rights on the receiving party.
• Permitted disclosure — limited to directors, employees, and professional advisers (lawyers, accountants, bankers) who need it for JV evaluation and are bound by equivalent obligations.
• Survival on failure — obligations continue in full whether or not the JV proceeds to completion.
• Return or destruction — if the JV is abandoned, each party returns or certifies destruction of the other's confidential materials.
• Non-circumvention (optional) — prevents either partner using the other's contacts or relationships to bypass them and deal directly.
• PIDA 1998 whistleblowing carve-out — mandatory where any employees or workers will be involved in the joint venture due-diligence process.

What a JV NDA does not cover

A non-disclosure agreement is a pre-formation document. It does not:

• Allocate equity, profit share or control in the joint venture
• Assign or licence intellectual property — those provisions belong in the JV agreement itself
• Prevent a party from competing with the other in their existing business (only a specific non-compete clause can do this)
• Bind parties to proceed with the JV — an NDA creates no obligation to transact
• Replace heads of terms, a shareholders agreement or a formal joint venture deed

Duration and what happens when the JV proceeds

Most UK joint venture NDAs run for two to five years from the date of signing. Trade secrets — proprietary technology, pricing models, client lists — should be protected indefinitely because their commercial sensitivity does not expire.

When the JV proceeds to a full agreement, confidentiality is typically governed by the Joint Venture Agreement. Best practice is to include a supersession clause in the JV agreement that carries forward the NDA's obligations for pre-formation disclosures while the ongoing agreement governs operational confidentiality.

If the JV does not proceed, the NDA continues to run for its full term. This 'fallback' protection is one of the most important reasons to sign the NDA early.

Governing law and jurisdiction

NDASafe Mutual NDA templates offer three governing-law options: England and Wales (default), Scotland, and Northern Ireland. For a cross-border JV involving a non-UK party, the governing law clause requires careful consideration — English law NDAs are widely accepted internationally but may need a jurisdiction agreement (exclusive or non-exclusive submission to English courts) to be enforceable against an overseas partner.

For complex cross-border JVs or those involving significant IP, take independent legal advice on choice of law and jurisdiction before signing.
