Key Takeaways
- Co-mediation means two mediators working together on the same case, rather than the usual single mediator.
- It tends to help where one person feels unheard, where the issues span both children and complex finances, or where sessions keep stalling.
- At Mediate UK, a second mediator is free where they are there to train, and free where we decide a second mediator is needed for safety or to let the case progress.
- Where you ask for a second mediator yourself, co-mediation costs an extra £60 plus VAT per person per hour.
- Legal aid for family mediation is means-tested only, and many child arrangements cases also qualify for the £500 family mediation voucher.
- Co-mediation is not automatic. It is agreed between you, your ex-partner and the mediator, usually after the MIAM.
What is co-mediation?
Co-mediation is family mediation run by two mediators working together with the same couple, instead of one. The pair are usually chosen for different strengths, such as one with a legal background and one with a background in child welfare or finance, or a male and female mediator working as a team. It is used where a single mediator would struggle to hold the balance, keep the session moving, or cover the range of issues on the table.
Most people arrive at co-mediation sideways. They have already looked at how mediation usually works, and something about the standard picture does not quite fit. Perhaps one of you is worried the mediator will side with the other. Perhaps the finances are tangled and the child arrangements are contested, and one person cannot realistically be expert in both. Perhaps you tried a session and it went nowhere.
This guide explains what two mediators actually add, when co-mediation is worth it and when it is not, what it costs in the UK, and how to ask for it. It also covers the funding, because a second mediator does not always mean a second bill.
Two mediators in the same session, used where a case is complex, where the balance in the room needs careful handling, or where things have stalled. In most cases there is no extra charge.
What Is Co-Mediation, and How Does It Differ From Standard Mediation?
In standard family mediation, one mediator sits with both of you and helps you work through the decisions you need to make. In co-mediation, two mediators do that job together. Both are impartial. Neither represents either of you. The difference is capacity and balance, not power.
The practical differences look like this:
- Two sets of eyes: while one mediator is working with a point, the other is watching the room, catching what is not being said and noting what has been skipped.
- Two skill sets: mediators come from different professional backgrounds, so a pairing can cover pensions and business assets alongside the needs of a seven-year-old.
- Balance in the room: where one person is convinced the mediator will not understand them, a second mediator changes that dynamic without anyone taking sides.
- Shared load in tough sessions: one mediator can stay with a difficult exchange while the other keeps the agenda on track.
It is worth separating co-mediation from the other formats people often confuse it with. It is not shuttle mediation, where you sit in separate rooms and one mediator moves between you. It is not child inclusive mediation, where a specially trained mediator meets your child directly. You can combine co-mediation with either of those, but they answer different problems.
Why Would Two Mediators in Mediation Help Your Case?
Having two mediators in mediation is not better by default. It helps in specific situations, and those situations are worth naming honestly.
Is Co-Mediation Useful If One of You Feels the Mediator Is Taking Sides?
This is the most common reason people ask about it. Mediators are impartial, and it matters that both of you believe that, not just that it is true. If one person cannot shake the feeling that the mediator is closer to the other person’s position, that belief will shape everything they say in the session. A second mediator often settles it, particularly where a male and female pairing addresses the concern directly.
Does Co-Mediation Help When the Finances and the Children Are Both Contested?
Yes, and this is where the pairing earns its place most clearly. A case involving a business valuation, a defined benefit pension and a disputed term-time schedule asks a lot of one person. Pairing a mediator with a financial or legal background alongside one whose experience sits with children and parenting means neither area gets the thinner treatment.
Can Two Mediators Keep a High Conflict Case Moving?
Sometimes. Where sessions keep circling the same argument, a second mediator can hold the difficult conversation while the first keeps the session pointed at the decisions that still need making. Two mediators can also debrief between sessions, which often surfaces something the room missed.
A stalled case that moved with a second mediator
A couple in their late forties came to us after two sessions elsewhere had gone nowhere. He ran a small building firm, she had given up work for eleven years, and every conversation about the business collapsed into a row about whose effort had built it. We brought in a second mediator at no extra cost, one with a finance background and one who focused on the parenting side. The finance mediator took the business questions apart into separate, answerable pieces. The other kept the two school-age children in view. They reached a full agreement in three further sessions. Details changed to protect privacy.
When Is Co-Mediation Not the Right Choice?
Plenty of cases do not need it, and adding a second mediator where it is not needed can slow things down rather than speed them up. Co-mediation is usually not the answer where:
- The issues are straightforward: a single dispute about holiday dates rarely benefits from two professionals in the room.
- Cost is the deciding factor: if you have asked for the second mediator yourself, the hourly rate goes up, and the money may be better spent on legal advice or the drafting of your agreement.
- The real problem is the format: if the difficulty is being in the same virtual room as your ex-partner, shuttle mediation solves that far more directly.
- Only one of you wants it: co-mediation is agreed by both parties and the mediator. It is not something one person can impose.
“We do not suggest a second mediator to sell more hours. In most of the cases where we use one, the client pays nothing extra, because we are the ones who decided the case needed it. What we look for is a specific reason: one person who cannot believe the process is fair, or issues that genuinely sit in two different areas of expertise. If neither of those is true, one experienced mediator is usually the better answer.”

How Does a Co-Mediation Session Actually Work?
The structure is the same as any other mediation. You each attend a MIAM first, which is a separate private meeting with a mediator to check that mediation suits your situation. If you are unsure what that involves, our guide on what a MIAM involves covers it step by step.
From there, joint sessions run in the usual way, typically 90 minutes each, with around 95 per cent of our sessions held online. In a co-mediated session, one mediator normally leads and the other supports, and they will often swap that role depending on the subject in front of you. Both will be introduced at the start, and both are bound by the same confidentiality and impartiality obligations. Mediate UK’s mediators are members of the Family Mediation Council, and you can see the team on our page for our mediators.
Not sure whether your case needs one mediator or two?
Start with a MIAM. It is a private meeting, so you can say exactly what worries you about the process before anyone sits down together. If a second mediator would help, we will tell you, and in many cases there is no extra charge.
How Much Does Co-Mediation Cost in the UK?
This is where most providers go quiet, so here is our position in full. The co-mediation cost in the UK depends entirely on who decided the second mediator was needed. At Mediate UK there are three situations, and in two of them you pay nothing extra.
| Situation | What you pay |
|---|---|
| The second mediator is with us for training purposes | No extra charge |
| We decide a second mediator is needed for safety, or to let the case progress | No extra charge |
| You ask us for a second mediator | £60 plus VAT per person, per hour, on top of the standard session rate |
For context, a standard joint mediation session online is £120 plus VAT per person per hour, and a MIAM is £115 plus VAT. So a client-requested co-mediation session runs at £180 plus VAT per person per hour. Full details of every rate sit on our page covering mediation costs and payment options.
Set that against the alternative. According to MoneyHelper, contested financial court proceedings can cost £30,000 plus VAT or more each. Ministry of Justice figures reported by Today’s Family Lawyer put the average time for private law children cases to be disposed of at 37 weeks during 2025. Even at the higher co-mediation rate, the gap is considerable.
Could legal aid or the £500 voucher cover this?
Legal aid for family mediation is means-tested only. It is not gated on domestic abuse or on the type of dispute. If you meet the income, savings and capital rules, your MIAM and your mediation sessions are free to you. Mediate UK is a Legal Aid Agency contracted provider, so legal aid mediation is available through us directly. You can check your legal aid eligibility in a couple of minutes, or use the government’s check if you can get legal aid tool.
Legal aid for a solicitor is a separate scheme. It was withdrawn for most private family cases on 1 April 2013 under LASPO, and is now available mainly to victims of domestic abuse and in cases involving child safety, where you can provide evidence and you also pass the means test.
There is also the £500 family mediation voucher scheme, which is a one-off government contribution of up to £500 per family towards mediation sessions. It is not means-tested, so income and assets do not come into it. It applies to cases involving child arrangements, or family finances where there is also a child dispute, and a finance-only case does not qualify. It does not cover the MIAM. Only an FMC-authorised mediator can apply it, and we do that on your behalf. The scheme is confirmed by the Family Mediation Council and remains available subject to funding, as of August 2026.
How Do You Ask for Co-Mediation?
You do not need to work it out before you get in touch. The process is straightforward:
- Raise it at your MIAM. The MIAM is private, so this is the place to say plainly what concerns you, whether that is the balance in the room or the range of issues.
- We assess whether it will help. If we think a second mediator is needed for safety or to let the case move, we will say so, and there is no extra charge.
- Both of you agree. Co-mediation only goes ahead where both parties and the mediator are content with it.
- We match the pairing to the case. That might mean a finance and children split, or a male and female pairing, depending on what the case actually needs.
- Sessions run as normal. Same format, same length, same confidentiality, with two mediators in the room.
Whether you use one mediator or two, the destination is the same. Across 2025 we recorded a 90 per cent agreement rate among clients who completed joint mediation, and the methodology behind that sits on our page covering our 2025 mediation outcomes. You can read more about the format itself on our co-mediation service page.
Family Law Service
Making your financial agreement legally binding
Whatever mediation format you use, a financial agreement only becomes binding once it is approved by the court as a consent order. Our sister service, Family Law Service, drafts and files clean break consent orders for a fixed fee, so there are no surprises at the end.
Summary
Co-mediation puts two mediators in the room instead of one. It helps most where the balance feels wrong to one of you, where the issues genuinely span two areas of expertise, or where a case has stalled. It is not the right answer for a simple dispute, and it is not something one person can insist on. At Mediate UK the second mediator is free where they are training or where we decide the case needs one, and £60 plus VAT per person per hour where you request it. Legal aid for mediation is means-tested only, and the £500 voucher may apply to child arrangements cases regardless of income. The place to raise it is your MIAM.
Frequently Asked Questions
What is co-mediation in family mediation?
Co-mediation is family mediation run by two impartial mediators working together with the same couple. The pairing is usually chosen for complementary strengths, such as one mediator with a legal or financial background and one with experience of children and parenting.
Can you request two mediators in mediation?
Yes. You can raise it at your MIAM or at any point during the process. Co-mediation goes ahead where both parties and the mediator agree it will help, so it is not something one person can require on their own.
How much does co-mediation cost in the UK?
At Mediate UK there is no extra charge where the second mediator is present for training, or where we decide a second mediator is needed for safety or to let the case progress. Where you ask for a second mediator yourself, it is an additional £60 plus VAT per person per hour on top of the standard session rate.
Can you have a male and a female mediator?
Yes. A male and female pairing is one of the more common co-mediation models, and it is often used where one person is worried that a single mediator will not understand their position. All mediators are impartial regardless of the pairing, but a mixed pairing can help both people feel that from the start.
Is co-mediation the same as shuttle mediation?
No. Co-mediation is about how many mediators are involved. Shuttle mediation is about where you sit, with each person in a separate room and the mediator moving between you. The two can be combined if that suits your case.
Does the £500 voucher cover co-mediation?
The family mediation voucher is a contribution of up to £500 per family towards mediation sessions, and it can be applied to co-mediated sessions in the same way. It is available for cases involving child arrangements, or family finances where there is also a child dispute, and it does not cover the cost of the MIAM.
Does co-mediation take longer than standard mediation?
Not usually. Sessions run to the same length, and in cases that have stalled a second mediator often reduces the number of sessions needed rather than adding to it.
