The Role of Lawyers in Mediation

A mediation date is fixed, the papers are being prepared, and one question usually follows quite quickly: do we need the solicitors there?

That question matters because mediation is sometimes misunderstood as a lawyer-free process in which legal advice is somehow set aside. In reality, the position is more practical than that. Civil mediation can take place before legal action or while legal action is ongoing, and the published guidance for civil and commercial mediation expressly envisages cases where lawyers are involved and cases where they are not. At the same time, mediators are neutral and do not provide legal advice, which means the question is not whether lawyers are allowed in mediation, but how they are best used within it.

This is why the role of solicitors in mediation is often misunderstood. Good legal representation can make mediation more focused, more realistic, and more effective. Used badly, lawyers can also make mediation feel like a mini-trial and reduce the flexibility that makes the process valuable in the first place. The real issue is not whether lawyers belong in mediation. It is what function they are performing when they are there.

Do You Need a Lawyer in Mediation?

Not always.

Civil and commercial mediation guidance from the Civil Mediation Council says that parties' lawyers often select the mediator, agree a date and location, settle the terms of the mediation agreement, and prepare written summaries and supporting documents. It then adds that, where lawyers are not instructed to assist, the parties undertake those tasks themselves. That makes clear that mediation can work with or without lawyers, depending on the dispute and the needs of the participants.

That said, whether you should have a solicitor in mediation is a different question from whether you must. In practice, the more legally or commercially complex the dispute, the more likely legal representation in mediation will add value. The same CMC guidance says preparation usually includes consideration of legal advice, the strengths and weaknesses of the case, the costs and time involved in litigating to trial, settlement expectations, and negotiation strategy. Those are all areas where lawyers often help clients think more clearly.

There is another reason the question matters. The Law Society's public guidance says mediators are neutral and cannot provide advice. That means a mediator can help participants negotiate and reality-test positions, but not advise one side on its legal rights or whether a proposed settlement is in its best interests. If that advice is needed, it has to come from somewhere else, and that is where a solicitor or barrister may be important.

What Is the Role of Lawyers in Mediation?

The core role of lawyers in mediation is not to replace the mediator. It is to advise and support the client within the mediation process.

In published CMC guidance, the legal work around mediation includes agreeing the mediation framework, preparing case summaries and document bundles, advising on legal strengths and weaknesses, considering the costs and timeline to trial, and helping shape negotiation strategy. The same guidance also notes that mediators usually hold pre-mediation meetings with the lawyers and, if they attend, the clients.

That means the solicitor mediation role usually includes four practical functions.

When Lawyers Add Value in Mediation — and When They Can Get in the Way

Lawyers usually add most value when they bring clarity, realism, and structure.

The CMC guidance says preparation should include discussion of strengths and weaknesses, the commercial context, the pros and cons of settlement, the costs associated with litigating through to trial, the timeline to trial, and negotiation strategy. That is precisely the kind of disciplined preparation that helps mediation work well.

The Law Society also recognises that representing a client in mediation is not the same as adversarial advocacy. Its judicial mediation practice note says advisers dealing with a mediation have a different role to play than when they are conducting adversarial advocacy before the Employment Tribunal. That is a useful way of understanding the point more broadly. Good lawyers in mediation do not simply repeat courtroom positions. They help clients make informed settlement decisions.

The risk, by contrast, is that lawyers can get in the way if they approach mediation exactly like trial preparation. If every discussion is treated as a point-scoring exercise, the process can become too rigid and positional. That is not because lawyers are a problem in mediation. It is because mediation requires a different professional posture: one that combines legal analysis with negotiation judgment. Mediation works best when the lawyer is not trying to perform the mediator's function and the mediator is not being asked to provide legal advice. The clearer those boundaries are, the better the process usually works.

How Lawyers and Mediators Work Together

Lawyers and mediators do different jobs.

The mediator is neutral, independent, and there to assist the participants in working towards a negotiated settlement. GOV.UK describes civil mediation as a flexible and confidential process in which an independent and impartial mediator helps the parties talk through the issues and negotiate. The Law Society's public guidance says mediators are neutral and cannot provide advice.

The lawyer, by contrast, is not neutral. The lawyer advises the client, protects the client's interests, helps assess risk, and supports decision-making. CMC guidance shows that lawyers may help with choosing the mediator, settling the mediation agreement, preparing papers, discussing strengths and weaknesses, and shaping settlement strategy.

Those functions are complementary, not conflicting. The mediator manages the process. The lawyer advises the client within that process. The mediator helps the participants move beyond fixed positions. The lawyer helps the client decide what can safely and sensibly be agreed. That is one reason mediation is not anti-legal. Properly used, it is professionally aligned with legal advice rather than opposed to it.

Practical Considerations

Why This Matters for Clients

For clients, the real takeaway is straightforward. Mediation does not require the absence of lawyers. It requires the right use of lawyers.

Some disputes can be mediated effectively without solicitors attending. Others benefit significantly from legal representation, particularly where the issues are complex, the stakes are high, or the settlement terms need careful drafting. The deciding question is usually not "Do I need a lawyer for mediation?" in the abstract. It is "What legal support will help me use this mediation well?"

For Mediation Chambers, that is the practical position. Mediation works best when participants, mediators, and legal representatives each understand their role clearly and use the process for what it is meant to achieve: informed, structured, and realistic resolution.
