Divorce Non-Disclosure Agreement (NDA): UK Guide | LegalDocuments.co.uk
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
When a marriage ends, the conversations that follow can be some of the most personal and financially sensitive of your life. Household finances, business interests, inheritances, health matters, and private family information often surface during negotiations, and not every spouse feels comfortable relying on goodwill alone to keep those details out of circulation.
A non-disclosure agreement, sometimes called a confidentiality agreement, is one tool some separating couples use to put firm boundaries around what can be shared and with whom. This guide walks through how NDAs work in the divorce context in England and Wales, what they typically cover, where their limits lie, and the sensible questions to ask before you sign one.
It is written for people going through separation themselves, not for lawyers, so the focus is on clarity rather than jargon.
What this document is
A divorce NDA is a contract between spouses (and sometimes their wider advisers or family members) that places restrictions on sharing information connected to the breakdown of the marriage. The agreement sets out which categories of information are treated as confidential, who is allowed to see that information, and what happens if someone talks when they shouldn't.
In practice, the information protected tends to fall into a few recurring buckets: household and personal finances, business valuations and trade secrets, health or medical history, details about children, allegations made during negotiations, and anything already discussed in mediation or round-table settlement meetings. An NDA does not override a court's powers, nor can it be used to hide wrongdoing or block someone from reporting a crime.
It sits alongside the divorce process rather than replacing any part of it, and it is most useful where one or both spouses have a genuine, legitimate reason to keep private matters private, whether that is protecting children, safeguarding a business, or simply maintaining dignity during an emotional period.
How to use this document
- Work out what you actually need to protect. Before drafting anything, make a list of the categories of information that genuinely need confidentiality. This might include business accounts, trust arrangements, health conditions, children's schooling, or communications from mediation. Being specific matters, because overly broad NDAs are harder to enforce and can feel oppressive to the other side.
- Agree the scope with your spouse. An NDA only works if both parties sign it willingly, so the terms need to be negotiated rather than imposed. Discuss who the restrictions apply to, how long they last, whether they cover social media and verbal conversations, and what carve-outs are sensible, for example permitting disclosure to accountants, therapists, or close family where appropriate.
- Set out the exceptions clearly. Every well-drafted NDA recognises that confidentiality has limits. The agreement should make clear that disclosures required by a court, HMRC, regulators, or the police are permitted, and that either party can take independent legal advice without breaching the agreement. Leaving these exceptions out creates an agreement that may not hold up.
- Decide what happens if someone breaches it. The agreement should explain the consequences of a breach, which might include an injunction to stop further disclosure or a claim for losses caused. Be realistic here, because courts will not enforce penalties that look punitive rather than compensatory, and vague consequences tend to cause more arguments than they solve.
- Sign, date, and keep copies. Once both parties are comfortable with the wording, sign the agreement, date it, and each keep a copy in a secure place. If the NDA is being used alongside a consent order or financial remedy application, make sure your respective advisers know it exists so it can be referred to consistently during the wider divorce process.

Common questions
Q Is a divorce NDA legally enforceable in England and Wales?
An NDA between spouses can be enforceable as a contract provided it meets the usual requirements: both parties enter it freely, there is something of value exchanged (often mutual confidentiality), and the terms are reasonably clear. Courts will not, however, enforce provisions that try to conceal criminality, prevent someone reporting abuse, or block disclosures required by law. Enforceability always depends on the specific wording and circumstances.
Q Can an NDA stop my spouse reporting domestic abuse or a crime?
No. An NDA cannot lawfully be used to silence someone about abuse, criminal conduct, safeguarding concerns, or information that a person is entitled to report to the police, a regulator, or a medical professional. Any clause attempting this would be unenforceable and could attract serious criticism from a court. Confidentiality agreements are for legitimate private matters, not for suppressing wrongdoing.
Q Do I need an NDA if we are already going through mediation?
Discussions within family mediation are already treated as confidential and legally privileged in most circumstances, so a separate NDA is not always necessary. Some couples still choose to sign one where sensitive business, financial, or reputational matters go beyond what mediation privilege covers, or where third parties such as advisers and family members need to be bound by the same restrictions.
Q Can an NDA prevent my spouse from talking about the divorce on social media?
Yes, a well-drafted NDA can include specific restrictions on social media posts, blogs, podcasts, and interviews relating to the marriage or its breakdown. These provisions are common in higher-profile cases. For them to work, the agreement needs to define what counts as a public statement and make clear which topics fall within the restriction, so there is no ambiguity later.
Q Does signing an NDA affect financial disclosure during divorce?
No. Both spouses are still under a duty of full and frank financial disclosure to each other and to the court during financial proceedings. An NDA governs what happens to that information outside the proceedings, not what needs to be shared within them. Anyone using an NDA to withhold disclosure from the other side or the court would be acting improperly.
Q How long should a divorce NDA last?
There is no fixed answer. Some NDAs last indefinitely for genuinely sensitive information such as business secrets or medical matters, while others run for a set number of years. The duration should match what is being protected: longer for information that remains sensitive over time, shorter where the commercial or reputational risk naturally fades. Overly long restrictions on ordinary information are harder to justify.
Q Can I include our children in a divorce NDA?
You can include provisions protecting information about children, such as their school, health, or whereabouts, and this is often sensible. What you cannot do is use an NDA to prevent a child speaking to professionals, or to override the court's welfare jurisdiction. Any child-related provisions should be drafted carefully so they support safeguarding rather than undermine it.
