You might be excited about a possible joint venture, but a little cautious too. Before you share pricing, customer insights, product plans or financials, you need a safe way to talk openly without handing over your business secrets.
A mutual NDA can do exactly that. It protects both sides while you explore the opportunity, test whether the relationship works and decide whether to move on to a full joint venture agreement.
The key is making sure the NDA is clear enough to be useful. A vague confidentiality agreement can feel reassuring, but when something goes wrong, the details matter.
Do You Need A Mutual NDA Before Joint Venture Talks?
Yes, you should usually have a mutual NDA in place before either side shares sensitive information. If both businesses will be disclosing information, a mutual non disclosure agreement is generally fairer than a one-way NDA.
A joint venture discussion can move quickly. You might start with a simple coffee chat, then move into pricing models, customer data, software access, manufacturing processes or supplier contacts. Once that information is shared, it can be very hard to put it back in the box.
A mutual NDA helps by setting out:
- what information is confidential
- why each side can use it
- who is allowed to see it
- what happens if the joint venture doesn't go ahead
- what remedies may be available if someone misuses the information
It also sets the tone. You're showing the other party that you're serious, organised and prepared to protect both businesses from day one.
Say Maya runs a SaaS business and Tom runs a marketing agency. They're exploring a joint package for retailers. Maya needs to show Tom screenshots of her product roadmap and usage data from 4,000 customers. Tom needs to share his campaign margins and client acquisition process. A mutual NDA lets both sides review the opportunity without either side feeling exposed.
What Should A Mutual NDA Cover?
A mutual NDA should cover the full life cycle of the discussions, from what can be shared to what must happen when talks end. A confidentiality agreement template in the UK can be a useful starting point, but templates often miss details that matter for your exact collaboration.
Here is a practical clause-by-clause outline you can use to check what your draft covers. This isn't a finished legal document, and a lawyer should tailor it before you use it.
- Parties: Write the full legal names of both businesses, including company numbers if they're UK companies registered with Companies House.
- Background: Briefly describe the proposed collaboration or joint venture discussions.
- Purpose: State exactly why information is being shared, such as assessing a possible joint venture for a named product, project or market.
- Definition Of Confidential Information: Include business, technical, financial, customer, supplier, marketing and operational information, whether shared orally, in writing or electronically.
- Obligations: Require each party to keep information confidential, use reasonable security measures, follow any agreed information security policy and only use the information for the stated purpose.
- Permitted Disclosures: Say who can receive the information, such as directors, employees, advisers and contractors who need to know.
- Exclusions: List information that isn't protected, such as information already public or already known before disclosure.
- Personal Data: Add UK GDPR and Data Protection Act 2018 wording if any personal data may be shared.
- Return Or Destruction: Explain what must happen to documents, files, copies, notes and extracts when requested or when talks end.
- Term: Set how long the NDA lasts and how long confidentiality obligations continue.
- Intellectual Property: Confirm that sharing information doesn't transfer ownership or grant a licence unless the parties agree otherwise in a data licence agreement or another written agreement.
- No Obligation To Proceed: Make clear that signing the NDA doesn't force either party to enter an incorporated or unincorporated joint venture.
- Remedies And Enforcement: Include practical consequences for breach, including urgent relief where appropriate.
- Governing Law And Jurisdiction: For England and Wales, say the agreement is governed by the law of England and Wales and which courts can deal with disputes.
What Information Should Be Protected?
The NDA should protect information that gives your business commercial value or would cause harm if it was misused or disclosed. The definition should be broad enough to cover what you'll actually share, but not so broad that it becomes unclear.
For joint venture talks, protected information often includes:
- pricing, margins, budgets and forecasts
- customer lists, leads and sales data
- supplier names, costs and contract terms
- business plans, pitch decks and market research
- software code, product roadmaps and technical documents
- trade secrets, know-how and manufacturing processes
- marketing strategies, campaign results and analytics
- employee, contractor or adviser details where relevant
Trade secrets can also be protected under the Trade Secrets (Enforcement, etc.) Regulations 2018 if the information is secret, has commercial value because it's secret and has been subject to reasonable steps to keep it secret. A properly drafted NDA is one of those reasonable steps.
You should also think about how information is marked or identified. Some NDAs only protect information labelled confidential, but that can be risky if you have fast-moving calls and meetings. A better approach is often to protect information that's identified as confidential, or that a reasonable business would understand to be confidential from the context.
If personal data will be shared, an NDA on its own may not be enough. Under the UK GDPR and the Data Protection Act 2018, you'll need to think about your lawful basis, data minimisation, security, retention and whether the parties are controllers, joint controllers or processors. The Information Commissioner's Office expects businesses to handle personal data carefully, even during early commercial talks.
How Should Permitted Use And Sharing Work?
The NDA should say that confidential information can only be used for the agreed purpose. This is one of the most important clauses because it stops the other side from using your information for a different project, pitch or competitor opportunity.
Your permitted use clause should be specific. For example, instead of saying information can be used for business discussions, say it can be used to evaluate and negotiate a potential joint venture to develop and sell a named product or service in the UK.
You should also control who can access the information. A sensible NDA usually allows disclosure to people who genuinely need to know, such as:
- directors and senior managers involved in the negotiations
- employees working on the proposed collaboration
- accountants, lawyers and other professional advisers
- contractors or consultants who are bound by confidentiality duties
- group companies, but only if that makes sense for the deal
Be careful with group companies. If you're speaking to one company in a larger group, you may not want your information passed around the entire group without control.
A Practical Example
Maya and Tom agree their NDA will allow each side to share information with up to 6 named team members and their professional advisers. The purpose is limited to assessing a joint retail SaaS and marketing package for a 6 month pilot.
Tom later wants to show Maya's dashboard screenshots to another agency he works with. The NDA doesn't allow that unless Maya gives written permission first. That gives Maya a clear basis to say no, or to approve it only if the other agency signs its own confidentiality undertaking.
This is where a joint venture NDA earns its keep. It doesn't just say keep things secret. It tells everyone how the information can move, who can see it and where the boundary is.
What Exclusions And Time Limits Should You Include?
The NDA should include sensible exclusions and clear time limits, because not every piece of information can or should stay confidential forever. Without exclusions, the agreement may be harder to apply in practice.
Common exclusions cover information that:
- is already public, unless it became public because of a breach
- was already known by the receiving party before disclosure
- is received lawfully from someone else who isn't under a confidentiality duty
- is independently developed without using the confidential information
- must be disclosed by law, a regulator or a court order
If disclosure is legally required, the NDA can still ask the receiving party to give prompt notice where lawful, disclose only what is required and help protect the information as far as reasonably possible.
The term needs careful thought, especially if the talks may later lead to a joint venture agreement. Many commercial NDAs have confidentiality obligations lasting 2 to 5 years, but the right period depends on the information. A pricing model for a short campaign may only need protection for a few years. Source code, formulas, manufacturing know-how or trade secrets may need protection for as long as they remain confidential.
You should also separate the NDA term from the confidentiality period. The NDA might allow disclosures during a 6 month negotiation period, while confidentiality obligations continue for 3 years after the last disclosure. For trade secrets, you may want obligations to continue for as long as the information remains a trade secret.
Finally, make sure the NDA explains what happens when talks end, including whether any later joint venture dissolution terms will be needed. Return and destruction wording should cover hard copies, digital files, backups, notes, extracts and internal summaries. Some businesses need to keep one archival copy for legal, insurance or governance reasons, but that copy should stay confidential and not be used for any commercial purpose.
What Happens If The NDA Is Breached?
If the NDA is breached, you should act quickly, preserve evidence and get advice before sending anything too aggressive. Your first goal is usually to stop the misuse, limit the damage and keep your options open.
A practical first response might look like this:
- Pause further sharing: Stop sending new confidential information until you understand what's happened.
- Collect evidence: Save emails, messages, meeting notes, access logs, file download records and screenshots.
- Check the NDA: Look at the purpose clause, permitted disclosures, exclusions, return obligations and notice requirements.
- Ask for an explanation: Sometimes the issue is an accidental internal forward or a misunderstanding that can be fixed quickly.
- Send a written notice: If needed, require the other side to stop using the information, return or delete it and confirm what steps they've taken.
- Get urgent advice: If the information is commercially sensitive or time-critical, tailored advice can help you decide the next move.
Your NDA can include wording that recognises a breach may cause harm that money alone may not fix. In England and Wales, a court may grant an injunction in appropriate cases, but wording in the NDA doesn't guarantee that outcome. The court will still look at the facts, urgency, evidence and whether the remedy is fair.
Other possible consequences may include damages, an account of profits in some circumstances, return or destruction of information, and costs consequences if a dispute escalates.
The practical point is simpler: if the NDA is well drafted, you have a clearer path to stopping the problem and proving what the other side agreed not to do.
If personal data is involved, you may also need to consider data breach steps under the UK GDPR, including whether notification to the ICO or affected individuals is required. That assessment is fact-specific and timing can matter, so don't leave it until later.
Key Takeaways
- A mutual NDA is usually the right starting point when both businesses will share sensitive information before a joint venture is agreed.
- The purpose clause should be specific, so information can only be used for the exact collaboration you're exploring.
- Good NDA clauses cover confidential information, permitted disclosures, exclusions, personal data, IP, return of information, time limits and enforcement.
- If you're sharing personal data, the UK GDPR and Data Protection Act 2018 may require more than a standard confidentiality clause.
- Templates can help you see the structure, but your NDA should be tailored to the information, parties and deal.
- If something goes wrong, pause sharing, preserve evidence, check the NDA and get advice before the issue escalates.
