Key Takeaways
- In family mediation, a neutral mediator helps you and your ex reach your own agreement. In family arbitration, you appoint an arbitrator who acts like a private judge and makes the decision for you.
- The mediator never decides the outcome. The arbitrator does, and their decision is binding.
- Mediation tends to be less expensive and works best when both people are willing to talk. Arbitration suits couples who are stuck on one or two issues and want a firm answer without going to court.
- Both are private, both are quicker than a contested court case, and both can be turned into a legally binding court order.
- Most people in London start with a first mediation meeting, which is also where you can talk through whether arbitration might suit you better.
Family Arbitration vs Mediation
The difference between family arbitration vs mediation is who makes the final decision. In mediation, a trained mediator helps you and your former partner reach your own agreement, and nothing is decided for you. In arbitration, you both appoint an arbitrator who listens to each side and makes a binding decision, much like a judge would, but privately and on your timetable.
If you are weighing up family arbitration vs mediation, the difference comes down to one thing: who has the final say. Both are ways to sort out finances or child arrangements after a separation without stepping into a courtroom, and in London both usually begin with the same first meeting. This guide explains what each process is, how they compare on cost, speed and control, and how to work out which one fits your situation.
Both sit under the wider umbrella of non-court dispute resolution, or NCDR, the family law term for sorting things out away from a judge. Since April 2024 the Family Procedure Rules ask separating couples to seriously consider these options before asking a court to decide. For London families facing long waits at the family courts and rising legal costs, that shift matters more than ever.
What is family mediation?
Family mediation is a series of meetings where an independent, trained mediator helps you and your ex-partner talk through the issues and reach your own agreement. The mediator does not take sides and does not tell you what to do. Their job is to keep the conversation productive, make sure both voices are heard, and help you find practical solutions on things like where the children live, how holidays are split, or how the house and pensions are divided.
Because you keep control of the outcome, mediation works well when both people are willing to negotiate, even if there is still tension between you. It is confidential, and it is regulated by the Family Mediation Council, which sets the standards all accredited mediators work to. You can read more in our guide to family mediation in London.
Mediation itself does not make anything legally binding. Once you reach an agreement, the mediator writes it up in a document called a Memorandum of Understanding. For financial matters, a solicitor then turns this into a consent order that a judge approves, which is what makes it enforceable. Our guide to how a mediated agreement becomes legally binding walks through that final step.
What is family arbitration?
Family arbitration is a private process where you and your ex-partner appoint a qualified arbitrator to decide your case for you. The arbitrator is usually a senior family law barrister, solicitor or retired judge. You both agree to be bound by their decision before the process begins, so it is not something you can walk away from if you dislike the result.
In England and Wales, family arbitration runs through the scheme set up by the Institute of Family Law Arbitrators, known as IFLA. Financial arbitration operates under the Arbitration Act 1996, and there is a separate scheme for disputes about children. For money cases the arbitrator issues an award, and for children cases a determination. Both can then be turned into a court order.
Think of arbitration as hiring your own private judge. You choose who decides, you choose when and where it happens, and you avoid the queue at a busy London family court. The trade-off is that you hand the decision over. If you want to keep the final say for yourselves, mediation is the better fit.
Family arbitration vs mediation: the key differences
The clearest way to see the difference between family arbitration vs mediation is to line them up side by side.
| Mediation | Arbitration | |
| Who decides | You and your ex-partner | The arbitrator |
| Binding outcome | Not until made into a consent order | Yes, the decision is binding |
| Typical cost | Lower, shared between you | Higher, you pay the arbitrator’s fee |
| Best when | You can still negotiate together | You are stuck and need a decision |
| Control of outcome | Stays with you | Handed to the arbitrator |
| Privacy | Private and confidential | Private and confidential |
Cost and speed
Mediation is usually the more affordable route, and the cost is often shared between you. For child arrangements cases, you may also qualify for the government’s family mediation voucher, a one-off contribution of up to £500 towards the cost. It is not means-tested, but it only applies where there is a dispute about children, not to finance-only cases. You can check the current position on the Family Mediation Council vouchers page (as of July 2026).
Arbitration costs more because you are paying for the arbitrator’s time, but it is still typically quicker and less expensive than a fully contested court battle in London, where hearings can be months apart and legal fees mount up. With arbitration, you set the pace.
“We often say to London clients that mediation and arbitration are not rivals, they are neighbours on the same street. Most couples we see settle everything in mediation because they would rather shape their own agreement than have one imposed. But when people are genuinely deadlocked on one issue, say the value of a business or a pension, arbitration gives them a fast, private answer without the wait for a court date. Knowing both options exist takes a lot of the fear out of separating.”

Not sure which route fits your situation in London?
A first meeting is the easiest way to talk through mediation, arbitration and the other non-court options, and to see what works for your family. Our mediators cover Waterloo, St Pancras and Sutton, as well as online.
Which should you choose?
There is no single right answer, and the best choice depends on how much you and your ex-partner can still work together. As a rough guide:
- Choose mediation if you both want to reach your own agreement, keep costs down, and protect a working relationship for co-parenting.
- Choose arbitration if you are stuck on one or two specific issues, need a binding decision, and want to avoid a drawn-out court case.
- Consider both if you can agree most things in mediation but reach an impasse on a single point. You can mediate everything else and arbitrate only the sticking point.
That last option is more common than people expect. Using mediation and arbitration together lets you keep control of most decisions while getting a firm answer on the one issue you cannot resolve. Mediation, arbitration, collaborative law and solicitor-led negotiation all sit on the same menu, which we set out in full in our guide to alternative dispute resolution.
Making your agreement legally binding
Whichever route you take, the final financial outcome usually needs to become a consent order to be legally binding and enforceable. A mediated agreement is drafted into one, and an arbitration award is submitted to the court to be sealed as one. Getting that paperwork right protects both of you and draws a clean line under the finances. Our consent order guide explains how it works.

Ready to make your financial agreement official?
Once you have reached an agreement, our sister service can draft a clean break consent order for a fixed fee, so there are no surprises on cost.
Where a MIAM fits in
Before most court applications, you are expected to attend a Mediation Information and Assessment Meeting, known as a MIAM. It is a short, one-to-one meeting with a mediator who explains all your options, including mediation, arbitration and going to court, and helps you decide what suits your circumstances. It is the natural starting point even if you are not sure mediation is for you. Our MIAM guide for London covers what happens and how to prepare.
A couple in Clapham who used both
One London couple came to us after months of stalemate over the family home. In mediation they agreed the arrangements for their two children and the split of savings within three sessions. The only sticking point was the value they each placed on a small business. Rather than let that one issue send them to court, they arbitrated it alone. The arbitrator ruled on the business figure, and the rest of their mediated agreement was folded into a single consent order. Names and details have been changed.
Summary
The heart of family arbitration vs mediation is control. Mediation keeps the decision in your hands and a mediator helps you get there together, which usually makes it the less expensive and less stressful choice. Arbitration hands the decision to a private judge who gives you a binding answer, which is ideal when you are deadlocked but want to stay out of court.
They are not either-or. Many London families mediate most issues and arbitrate the odd one they cannot settle. A MIAM is the simplest way to talk it all through and find the right mix for you.
Frequently Asked Questions
Is arbitration or mediation better for divorce?
Neither is simply better. Mediation is better when you can still negotiate and want to keep control and costs down. Arbitration is better when you are deadlocked on a specific issue and need a binding decision without the delay of court. Many people use mediation first and only arbitrate what they cannot agree.
Is family arbitration legally binding?
Yes. When you enter family arbitration, you both agree in advance to be bound by the arbitrator’s decision. For financial cases the award is submitted to the court and sealed as a consent order, which makes it enforceable.
Is mediation cheaper than arbitration?
Usually, yes. In mediation the cost is often shared and, for child arrangements cases, a government voucher of up to £500 may help. Arbitration costs more because you pay the arbitrator’s fee, but it is still generally cheaper and faster than a fully contested court case.
Can you use mediation and arbitration together?
Yes, and it is a common approach. You can settle most of your issues in mediation and arbitrate only the point where you reach an impasse, then combine everything into one agreement. This keeps you in control of most decisions while still getting a firm answer on the sticking point.
Do I need a MIAM before arbitration?
A MIAM is required before most court applications rather than before arbitration itself, but attending one is still sensible. It is where a mediator explains mediation, arbitration and court, so you can choose the route that fits before committing to any of them.
