The principles of family mediation
Key facts
- Family mediation in England and Wales rests on five working principles: it is voluntary, the mediator is impartial, discussions are confidential, children’s welfare comes first, and the decisions are yours.
- The principles are not just good manners. They are professional obligations set out in the Family Mediation Council’s Code of Practice, which every FMC-registered mediator must follow.
- Confidentiality has defined limits: mediators must act where a child or adult is at risk of harm, and where the law on the proceeds of crime requires it.
- Proposals discussed in mediation are without prejudice, meaning they cannot be quoted later in court as concessions.
- You can withdraw from mediation at any point. So can the mediator, if the process stops being fair or safe.
Family mediation looks informal from the outside: two people, a mediator, a table or a video call. Underneath the informality sits a tight professional framework, and understanding it changes how the process feels. Each principle answers a worry people bring to their first session, from “will the mediator take my ex’s side?” to “can what I say be used against me?”
This page takes the five principles in turn and explains what each one means for you in practice. If you are starting from scratch, our complete guide to family mediation covers the process itself, and the MIAM guide explains the individual meeting where mediation begins.
Where the principles come from
Family mediation is a regulated profession. The Family Mediation Council (FMC) maintains the register of family mediators in England and Wales, and everyone on it works under the FMC Code of Practice, which sets out the aims, scope and general principles of family mediation along with the standards mediators must meet. Complaints can ultimately be escalated through the FMC’s standards framework, so the Code has teeth.
The principles also appear in the agreement to mediate, the document you both sign before joint sessions, which turns them into terms you can point to. If you want to check a mediator’s status, or understand what the letters after their name mean, see our guide to mediator accreditation: an FMCA-accredited mediator has completed supervised practice and a portfolio, and only FMC mediators can sign court forms and access the government voucher scheme.
The FMC Code of Practice is a living document, most recently updated in August 2025, with supplementary guidance covering online mediation and MIAMs. Your mediator is bound by the current version, whichever year you first signed your agreement to mediate.
Mediation is voluntary
Nobody can be ordered into mediation, and nobody can be kept there. The law requires most people to attend a MIAM, an individual meeting where mediation is explained and assessed, before applying to court, but the duty is to consider mediation, not to do it. From the first joint session to the last, either of you can stop, without giving the other a reason.
Voluntariness is what gives a mediated agreement its strength. Terms you chose, rather than terms imposed on you, are terms you are far more likely to keep to, which matters most where you will be co-parenting for years after the paperwork is done. It also means the pressure to “just sign” has no place in the room: a mediator who senses reluctance will slow down, not push through.
The mediator is impartial
The mediator does not act for either of you. They cannot advise you to take a deal, tell your ex-partner their proposal is mean, or nudge the outcome towards what they personally think is right. What they can do is give legal information that applies equally to you both, such as how courts approach housing needs, and manage the conversation so that the quieter or slower voice gets equal room.
Impartiality also covers conflicts of interest. A mediator who knows one of you socially, or has previously advised one of you professionally, must not take the case. If anything emerges mid-process that compromises their neutrality, they must say so and stand down.
People sometimes mistake balance for passivity. A good mediator is highly active: reframing, questioning, testing proposals against reality. The line they will not cross is siding. Our page on what a family mediator actually does shows what active impartiality looks like session by session.
Discussions are confidential, within defined limits
What is said in mediation stays there. The mediator will not report the content of your sessions to the court, to solicitors or to anyone else, and your MIAM is private even from your ex-partner. On top of that sits the without prejudice rule: proposals made in a genuine attempt to settle cannot be put before a judge as evidence of what you were once prepared to accept. You can float an idea on Tuesday and abandon it on Thursday with no cost.
Confidentiality is a principle, not an absolute, and the Code of Practice defines where it gives way. If anything suggests a child or adult is at risk of significant harm, the mediator must act, which can mean contacting social services. Disclosures indicating money laundering or other proceeds of crime trigger legal reporting duties that override the mediation’s privacy. And in rare cases a court can require evidence, for example about whether an agreement was actually concluded.
One document deliberately sits outside the protection: the open financial statement, which records the financial facts you both disclose so they can be reused if you later need solicitors or a court. The proposals stay private; the facts do not. How that distinction plays out when you formalise an agreement is explained in is family mediation legally binding?
Children’s welfare comes first
Family mediation is child-focused. Where there are children, the mediator will keep bringing the conversation back to their needs: their routines, schooling, relationships with both of you and with wider family. That mirrors the law, since the Children Act 1989 makes a child’s welfare the court’s paramount consideration, but in mediation it works as a practical discipline rather than a legal test. “What does Tuesday look like for Amelia?” cuts through an argument faster than any point of principle.
Being child-focused can also mean hearing from children directly. In child-inclusive mediation, a trained mediator meets your child separately and feeds back, with the child’s agreement, what they want you both to know. Children do not attend joint sessions and never make the decisions; the point is that decisions made about them are made with their views in the room.
The decisions are yours
Lawyers call this principle party self-determination: the people in the dispute, not the professional in the room, decide the outcome. The mediator holds the process, you hold the content. No proposal becomes an agreement until you both accept it, and the outcome document records your decisions in your words, not a professional’s recommendation.
The principle carries a responsibility with it. Because the mediator cannot advise you individually, you are expected to inform yourself, and mediators actively encourage each of you to take independent legal advice before turning proposals into anything binding. Getting a solicitor to review your agreement after mediation is not a sign the process failed; it is how the process is designed to finish.
What each principle means for you in practice
Here is the framework reduced to what you can actually rely on, and what is expected of you in return.
| Principle | What you can rely on | What is expected of you |
|---|---|---|
| Voluntary | You can pause or stop at any time, without penalty | Turning up willing to look for a settlement, not to go through the motions |
| Impartial | The mediator takes no side and has no stake in the outcome | Accepting the mediator will not referee old arguments or declare a winner |
| Confidential | Sessions are private and proposals are without prejudice | Respecting the same privacy, and understanding the safeguarding and crime limits |
| Child-focused | The agenda keeps returning to your children’s needs | Weighing proposals by what works for the children, not by the score between adults |
| Your decisions | Nothing is agreed until you both agree it | Full, honest disclosure and taking advice before you commit |
Notice how the principles interlock. Voluntariness is only real if you are informed, information depends on honest disclosure, and honesty is safest inside confidentiality. Remove one and the others weaken, which is why mediators treat them as a package rather than a menu.
Tomasz, a delivery driver from Wrexham, nearly refused mediation because his ex-partner Kate is a manager who, in his words, “wins every conversation”. In the first joint session the mediator noticed Kate answering for them both and changed the format: each of them got uninterrupted time to set out their view of the children’s week, with the mediator summarising before any response was allowed. When Kate produced a ready-made schedule in session two, the mediator did not endorse or criticise it; instead they tested it line by line against both parents’ shift patterns, which exposed that Tuesday handovers were impossible for Tomasz. The final plan kept Kate’s structure but moved midweek contact to Thursdays and added a school-holiday rota Tomasz proposed himself.
Impartiality did not mean treating the proposals equally. It meant making sure both people could genuinely shape the outcome.
Frequently asked questions
Can the mediator give us legal advice?
No. Mediators give legal information, which is general and applies to you both, such as explaining what a consent order is or how courts approach child arrangements. Advice, meaning a recommendation about what you personally should accept, has to come from your own solicitor, and mediators encourage both of you to get it between sessions.
Is everything I say in mediation confidential?
Almost everything. Sessions are private and settlement proposals are without prejudice, so they cannot be quoted in court. The exceptions are defined: a risk of significant harm to a child or adult, legal duties around the proceeds of crime, and the open financial statement, which records disclosed financial facts openly so they can be reused later.
What happens if the mediator thinks our agreement is unfair?
They cannot veto it, because the decisions are yours, but they are not a bystander either. A mediator who sees a seriously lopsided proposal will test it, make sure the disadvantaged person understands the implications, and urge independent legal advice before anything is formalised. If the process itself has become unfair, they can end the mediation.
Who enforces the Code of Practice?
The Family Mediation Council and its standards board oversee the profession. Every FMC-registered mediator works under the Code, is supervised by a professional practice consultant, and is subject to a complaints procedure, first through their own service and then through their FMC member organisation. Accreditation status can be checked on the FMC register.
Do the same principles apply to online mediation?
Yes, in full. The FMC publishes specific guidance on mediating by video, but the framework is identical: voluntary participation, an impartial mediator, confidential without prejudice discussions, a child-focused agenda and decisions that stay with you. Practicalities differ slightly, for example agreeing that nobody records the session or has anyone off-screen in the room.
