Most attorneys can recite that mediation is confidential. Rather fewer can say precisely what that protects, what it does not, and which documents are designed from the outset to end up in front of a judge. The distinction matters, because the advice a client relies on before the first session is usually given on the strength of that understanding.
Three protections, three different jobs
The first difficulty is vocabulary. Practitioners routinely use confidentiality, without prejudice and privilege as though they were synonyms. They are not, and conflating them produces advice that is confident and wrong.
| Protection | What it does | Principal source |
|---|---|---|
| Confidentiality | Restricts who may repeat what was said or produced in the process, including outside any litigation. It binds the parties, their representatives and the mediator, and it continues after the mediation ends. | Rule 41A(6), the agreement to mediate, and in Gauteng the Protocol. |
| Without prejudice | Restricts the use of settlement communications as evidence, so that a concession made in an attempt to resolve is not later deployed as an admission of liability. | The common law, reinforced by Rule 41A and by the agreement to mediate. |
| Legal professional privilege | Protects communications between a client and their legal adviser. It belongs to the client, and it is unaffected by whether a mediation happens at all. | The common law. |
A document can be confidential to the mediation and still be discoverable in the litigation. A communication can be without prejudice and still be repeatable to a third party in breach of a confidentiality undertaking. A privileged communication does not lose privilege because it was discussed in a caucus. Each question has to be asked separately.
What Rule 41A(6) actually says
The rule provides that, except as provided by law, or discoverable in terms of the Rules, or agreed between the parties, all communications and disclosures, whether oral or written, made at mediation proceedings are confidential and inadmissible in evidence.
Read that as four elements rather than one. The protection is broad in what it covers, catching oral and written material alike. But it carries three express carve-outs, and each of them is doing real work:
- Except as provided by law. Statutory reporting obligations, including the mandatory reporting duties under the Children's Act where a child may be at risk, are not displaced by the rule.
- Except as discoverable in terms of the Rules. The largest of the three in practice, and the one dealt with next.
- Except as agreed between the parties. The parties may consent to disclosure, which is also what allows a caucus disclosure to be carried across when the disclosing party authorises it.
Rule 76 of the Magistrates' Courts Rules is materially identical in the court-annexed regime. The two frameworks are distinct and should not be conflated, as we set out in what happens before the first Rule 41A mediation session.
The discoverability carve-out, and why it catches people out
This is the point at which client expectations most often diverge from the legal position. Parties frequently assume that producing a document in mediation somehow shelters it from the litigation. It does not.
A document that would ordinarily be discoverable in the litigation remains discoverable. Its status is preserved. A bank statement, a management account, a contract or a valuation does not acquire protection because it was handed across a mediation table.
What the rule protects is the mediation content: the offers, the concessions, the positions explored, the reasons given, the things said in an attempt to settle. Those are inadmissible. The underlying documents are not converted into privileged material.
The practical advice follows directly. Where a client is considering producing a document in mediation that has not yet been discovered, the question is not whether the mediation protects it. The question is whether it is discoverable anyway, and if so, whether there is any advantage in withholding it from a process designed to resolve the matter. In financially complex matters we deal with the disclosure question separately in full and frank financial disclosure in mediation.
Confidentiality before the agreement to mediate is signed
Rule 41A(4)(b) requires the parties to enter into an agreement to mediate before the mediation begins. That agreement is the principal contractual source of the confidentiality obligation, and its terms usually go further than the rule.
It follows that the position before signature is weaker than parties assume. Confidentiality attaches to the mediation process itself, and parties should not assume that anything said at a preliminary meeting is automatically inadmissible before the agreement to mediate is in place. Where sensitive ground is likely to be covered in early engagement, the sensible course is to get the agreement signed first, or to record an express interim confidentiality undertaking.
One further point on the notices themselves. The Rule 41A(2)(d) notice, and its Rule 72(4) counterpart in the Magistrates' Courts, are without-prejudice documents and are not filed with the registrar. They are procedural notices signalling a position on referral, not pleadings, and they should not be drafted as though a judge will read them at trial.

What actually reaches the court file
Rule 41A is not a sealed system. Several documents are designed to move from the mediation into the court record, and an attorney who treats the whole process as hermetic will be surprised at the wrong moment.
| Document | Function | Reaches the court? |
|---|---|---|
| Rule 41A notice and response | Signals agreement to or opposition to referral, with reasons. | No. Without prejudice and not filed with the registrar. |
| Agreement to mediate | The contract between the parties and the mediator governing the process. | Under the Gauteng Protocol it is filed with the court on conclusion, together with the minutes and report. |
| Joint minute recording the election to mediate | Required by Rule 41A(4)(a). Triggers the suspension of time limits under the Rules. | Yes. |
| Joint minute on conclusion | Records whether settlement was full, partial or not reached, and identifies issues no longer requiring a hearing. | Yes. Filed with the registrar. |
| Mediator's report | Records the outcome and the parties' participation. | Yes, under the Gauteng Protocol, filed electronically on Court Online. |
| Settlement agreement | The contract recording the terms agreed. | Only if the parties take it there. Rule 41A(8)(e) applies Rule 41 mutatis mutandis to making it an order of court. |
| Caucus content, offers and positions | The substance of the negotiation. | No, subject to the three carve-outs and to the tender position below. |
The point of the joint minute on conclusion is worth dwelling on, because it is genuinely useful. Where the mediation narrows the issues without resolving everything, the minute records what no longer requires a hearing. That is a court-facing document which shortens the trial, and it is one of the strongest arguments for treating a partly successful mediation as a success. We deal with the documents individually in Rule 41A mediation documents explained.
The offer or tender under Rule 41A(8)(d)
This is the exception most often missed, and it has direct costs consequences.
A without-prejudice offer or tender made in terms of Rule 41A(8)(d) may be disclosed to the court once judgment has been given, for the purposes of costs.
The sequencing is the whole point. The offer is shielded while the merits are being decided, so it cannot influence the judgment. It becomes visible afterwards, when the court turns to costs and asks what each party did to resolve the matter and when.
For an attorney this converts a settlement offer into a costs instrument. An offer pitched carefully during mediation, and properly recorded, may do considerable work months later even though the matter did not settle. An offer that was never properly documented does nothing at all.
The mediator as a witness
Where mediation does not resolve the matter and the litigation resumes, the question occasionally arises whether the mediator can be called to describe what happened.
The agreement to mediate will ordinarily provide that the mediator may not be subpoenaed or called to testify in any subsequent proceeding between the parties, and that the mediator's notes are not available for that purpose. Many agreements go further and provide for the destruction or return of the mediator's working notes after the process concludes.
That protection serves the process rather than the mediator. A mediator who might later be a witness is a mediator to whom nobody will speak candidly, and candour in caucus is the mechanism by which most matters actually resolve. Attorneys should check that this provision is present, and should resist any attempt to erode it.
Reporting participation without breaching confidence
The mediator's report creates an apparent tension. If the process is confidential, how can the mediator report on it at all?
The answer lies in the distinction between outcome and participation on the one hand, and the substance of the negotiation on the other. The report addresses whether the mediation took place, whether the parties attended, whether settlement was reached in whole or in part, and how the parties engaged with the process. It does not narrate the offers, the concessions or the reasoning.
South African authority supports the proposition that a party's bad faith may be indicated by the mediator without breaching the confidentiality of the process. In Kalagadi Manganese (Pty) Ltd v Industrial Development Corporation of South Africa Ltd [2021] ZAGPJHC 127 the court engaged at length with what constitutes bad faith participation, and treated dishonesty as one of its elements, in the context of the expectation that parties make a genuine attempt at non-adversarial resolution.
Advise the client that how they conduct themselves in the process is not invisible to the court, even though what they say is. Attending without authority, refusing to engage, or treating the session as a tick-box exercise can be recorded as a participation failure, and the court retains a discretion on costs. No adverse costs consequence is automatic, but the conduct is not shielded.
The Gauteng Protocol layer
For matters on the Gauteng civil trial roll, the Mediation Directive and Protocol add a further layer of confidentiality architecture, and it is more structural than most practitioners expect.
- The Protocol requires the mediation to be conducted in a confidential and without prejudice manner.
- Confidentiality is expressed to continue after the mediation ends, with carve-outs for the signed settlement agreement and for the mediator's report and joint minute filed with the court.
- Separate breakout rooms, whether physical or virtual, are required so that caucusing can occur with genuine privacy. This is a structural feature of the process, not a matter of preference.
- The Mediator's Report template includes a specific field recording whether a without-prejudice offer or tender was made, flagged for the trial court's attention on costs.
That last item is the Rule 41A(8)(d) mechanism operationalised. It is worth knowing that the form itself invites the point, because it means a well-judged tender is not merely protected but actively signposted to the court at the costs stage. The divisional mechanics are set out in the Rule 41A process under the Gauteng Protocol, and the wider costs picture in mediation in the Gauteng High Court.
Drafting the agreement to mediate
Because the rule sets a floor rather than a ceiling, the agreement to mediate is where the real confidentiality work is done. In commercial and reputation-sensitive matters, the following deserve attention rather than acceptance of a standard form:
- Scope. Whether confidentiality covers the existence of the mediation, not merely its content.
- Who is bound. Representatives, experts, support persons and administrative staff, not only the parties.
- The settlement terms. Confidentiality of the outcome is legally distinct from confidentiality of the process, and needs its own clause. This is a common drafting gap.
- Caucus rules. What the mediator may carry across, and on what authority.
- Recording and notes. Whether recording is prohibited, who may take notes, and what happens to them afterwards.
- Enforcement carve-out. Confidentiality must not be drafted so tightly that it prevents a party referring to the settlement in order to enforce it.
- Regulatory and fiduciary carve-outs. Where a listed company, a trustee or a regulated entity is a party, disclosure obligations exist that a confidentiality clause cannot override.
- Reporting. How the outcome will be reported, which in Rule 41A matters is partly prescribed.
Cancellation terms, termination and domicilium belong in the same review. Parties overlook them until the moment they matter.
What to tell the client before the first session
The conversation is short and worth having every time.
- What is said in the process is protected, and generally cannot be used against you later.
- Documents that would have to be discovered anyway remain discoverable. Producing them here changes nothing about that.
- Anything said to the mediator privately stays private unless you authorise it to be shared.
- The court will be told whether the mediation happened, whether it settled, and how the parties participated. It will not be told what was offered, except in the specific tender situation at the costs stage.
- The protection is strong but not unlimited. Where the law requires disclosure, the law prevails.
A client who understands those five points negotiates differently from one who believes either that nothing is protected or that everything is.
Frequently asked questions
Is everything said in a Rule 41A mediation confidential?
Rule 41A(6) protects communications and disclosures made at mediation proceedings, both oral and written, and renders them inadmissible in evidence. The protection is subject to three carve-outs: where the law provides otherwise, where the material is discoverable under the Rules, and where the parties agree. It is strong protection, but it is not unlimited.
Does producing a document in mediation protect it from discovery?
No. A document that would ordinarily be discoverable in the litigation remains discoverable, and its status is preserved. Mediation protects the content of the negotiation, meaning the offers, concessions and positions explored. It does not convert underlying documents into privileged material.
What is the difference between confidentiality and without prejudice?
Confidentiality restricts who may repeat what was said or produced, including outside any litigation, and it binds the parties and the mediator beyond the session itself. Without-prejudice protection restricts the use of settlement communications as evidence, so a concession made in an attempt to resolve is not later used as an admission. They overlap but are not the same, and legal professional privilege is a third question again.
What does the mediator's report tell the court?
It addresses the outcome and the parties' participation, meaning whether the mediation took place, whether settlement was reached in whole or in part, and how the parties engaged. It does not narrate the offers, concessions or reasoning. Under the Gauteng Protocol the report is filed together with the joint minute.
Can a without-prejudice offer made in mediation ever be shown to the court?
Yes, in a specific and limited way. An offer or tender made in terms of Rule 41A(8)(d) may be disclosed to the court once judgment has been given, for the purposes of costs. The sequencing protects the merits determination while allowing the court to see what each party did to resolve the matter when it turns to costs.
Can the mediator be called as a witness if the matter does not settle?
The agreement to mediate will ordinarily provide that the mediator may not be subpoenaed or called to testify in subsequent proceedings between the parties, and that the mediator's notes are not available for that purpose. Attorneys should confirm the clause is present, because the protection is what makes candour in caucus possible.
How long does mediation confidentiality last?
It continues after the mediation ends. The obligation binds the parties and the mediator beyond the session itself, subject to the carve-outs for the signed settlement agreement and for the documents the Rules and the applicable protocol require to be filed with the court.
