Family mediation privacy and confidentiality — what stays in the room

REVIEWED BY: Sean McNamara on 2026-08-30

One of mediation's core promises is privacy: what you discuss cannot be used against you in court if mediation fails. But the protection has defined edges, and there are things a mediator must report. This guide sets out what confidentiality actually covers. It is general information, not legal advice.

The three layers of protection

1. Legal privilege for legally aided mediation — for parties eligible for legal aid, mediation communications are covered by mediation privilege (Family Procedure Rules, rule 3.12 and PD3): nothing said can be disclosed in court except with both parties' consent or as required by law 2. Contractual confidentiality — private mediation agreements between you, your ex and the mediator contain mutual confidentiality clauses; breaching them is a contract claim 3. The practice rule: FMC-accredited mediators work under a code of practice requiring confidentiality, and mediators generally cannot be called as witnesses about the mediation

What this means in practice

Offers and admissions are protected: "I'd sell the house for £200k" said in mediation cannot be deployed as evidence if you later litigate
Your opening positions are not your case: judges will not hear "she admitted in mediation that…"
The mediator cannot be subpoenaed to testify about what you said — in most circumstances
The outcome can be used: if you reach agreement, the resulting memorandum of understanding or consent order is meant to go to solicitors/court — confidentiality protects the process, not a concluded deal

The exceptions — where confidentiality does NOT apply

Mediators must, and courts will, look beyond the room where:

Safeguarding: allegations or indications that a child or vulnerable adult is at risk of harm — mediators have duties to refer to children's services or police
Admissions of serious crime or intentions to commit one
Money laundering or fraud concerns — solicitors and mediators have statutory reporting duties (Proceeds of Crime Act / anti-money-laundering rules)
Both parties consent to disclosure — you can jointly agree to tell the court something
Enforcement of the agreement — where one party says a deal was reached and the other denies it, a court may need to examine limited evidence of what was agreed
Threats of violence — protecting people overrides process privacy

What the court sees after mediation

Only the documents the parties choose to produce:

The memorandum of understanding (MOU) — the summary of agreements, confidential between the parties unless they choose to share it
The open financial statement — the disclosure of financial facts, deliberately "open" so figures can travel into any court case
The consent order — if you convert the agreement, it's filed at court in the normal way

This split structure — confidential process, open financial facts — is deliberate: figures must be verifiable, positions must be free.

If mediation fails

You return to court (or start it) without the mediator or your mediation statements being dragged in
A MIAM completion form confirms you attended — that's all the court needs
The only mediation content that reaches court is what both parties put there
Note: unreasonable refusal to mediate can have costs consequences in some financial cases — the fact you tried (or they refused) is visible; what was said is not

Practical tips

1. Ask the mediator to explain confidentiality at the MIAM — a good mediator covers the ground rules including the safeguarding exceptions before you start 2. Sign the agreement to mediate knowingly — it sets out the confidentiality terms and the exceptions 3. Don't say anything in mediation you'd be devastated to have to prove elsewhere — the protection is strong but not absolute 4. Keep the financial disclosure — the open statement is the part you'll reuse with your solicitor or in proceedings
