Do You Need Mediation Before Family Court in the UK?

Your co-parent won't negotiate. Communication has collapsed. You're ready to let a judge sort it out — but before you can file a C100 application in England, you almost certainly have to sit through a mediation appointment first. Not optional. Not a suggestion. A legal requirement.

Here's what that process actually looks like, who can skip it, and how to make sure it counts.

The MIAM Is Mandatory — With Teeth

Under Family Procedure Rules Part 3 and Practice Direction 3A, any parent wanting to apply for a Child Arrangements Order must first attend a Mediation Information and Assessment Meeting (MIAM) with an authorised family mediator. The mediator assesses whether mediation is suitable for your situation, and you need their signed certificate before the court will accept your C100 application.

This isn't a full mediation session. A MIAM typically lasts around 45 minutes and costs £100 to £150 per person. The mediator explains how mediation works, assesses whether both parties can participate safely, and — if mediation isn't appropriate — issues the certificate you need to proceed to court.

The rules were tightened in 2024 to close loopholes parents had been using. The old geographic exemption — no mediator within 15 miles — barely applies now because online MIAMs are treated as universally available. To claim a distance exemption today, you need to prove you can't access an online meeting and that you contacted at least five authorised mediators within 15 miles, none of whom could offer an appointment within 15 business days.

Another closed loophole: a previously claimed MIAM exemption no longer carries over to a new application. If a dispute resurfaces, you go back to the mediator unless a current, independent exemption applies.

Valid MIAM Exemptions

Not everyone needs to attend. You can claim an exemption and go straight to court if:

• Domestic abuse: You have evidence of domestic abuse by the other party — a police report, protective injunction, refuge referral letter, or similar documentation
• Urgency: There's a risk of significant harm to the child (abduction threat, immediate safety concern) and delay would cause serious prejudice
• Previous MIAM attendance: The other party attended a MIAM in the last four months for the same dispute and mediation was assessed as unsuitable
• Other statutory exemptions: The current rules contain additional circumstances; check the C100 and FM1 instructions rather than assuming you qualify
• Child protection involvement: Local authority investigations or a child protection plan are currently active
• The other party is in prison or subject to conditions that prevent attendance

You declare your exemption on the C100 form itself, and the court can — and does — ask for supporting evidence. Claiming an exemption without documentation risks your application being returned.

If you attend a MIAM and the mediator determines that mediation isn't appropriate — for instance, because one party has a severe mental health condition or there's a significant power imbalance — they can issue the certificate needed to apply to court. This is not a way to skip the MIAM.

The £500 Family Mediation Voucher Scheme

If you do proceed to mediation, the government's Family Mediation Voucher Scheme provides up to £500 toward the cost of joint mediation sessions. This covers a significant portion of total mediation costs, which typically run between £400 and £1,500 depending on complexity and the number of sessions.

Key points about the voucher:

• It covers joint mediation sessions (not the initial MIAM, which you pay for separately)
• Both parties must agree to attempt mediation
• The mediator applies for the voucher on your behalf — you don't need to apply directly
• It is intended for eligible child-arrangements mediation sessions; check the current scheme rules before assuming it covers financial remedy or other property issues

Given that contested court proceedings can cost £3,000 to £15,000 per party, a mediation route — especially with the voucher subsidy — represents a fraction of the cost.

How to Prepare for Your MIAM

Walking into a MIAM cold is a missed opportunity. The mediator is assessing whether mediation could work for your situation, and what you bring to that meeting shapes their recommendation:

1. Write a one-page summary of the arrangements you want and the key points of disagreement. Keeping it structured shows the mediator you're ready to engage constructively
2. Bring supporting documents — school calendars, work schedules, any existing informal agreements about the children
3. Know your non-negotiables versus your flexible points. The mediator will explore whether there's enough common ground to mediate
4. Be honest about safety concerns. If there's a history of domestic abuse, coercive control, or intimidation, say so. The mediator needs this information to assess whether mediation is safe and appropriate

If the mediator determines mediation isn't suitable — because of a power imbalance, safety concerns, or the other party's refusal to participate — they'll issue the FM1 certificate you need to file your C100.

What Happens After the MIAM

Three outcomes are possible:

Mediation proceeds: Both parents agree to try mediation. Sessions are scheduled (typically two to four sessions over several weeks). If you reach an agreement, a mediator can prepare a Memorandum of Understanding — though this isn't legally binding until a solicitor converts it into a Consent Order approved by the court.

Mediation is assessed as unsuitable: The mediator signs off your FM1 certificate and you proceed to file your C100 application (£270 court fee).

One party refuses to attend: If your co-parent won't attend the MIAM despite being contacted, the mediator can still issue your certificate. The court takes note of which parent refused to engage with the process.

The Bigger Picture

The family court treats itself as a last resort. Judges routinely ask what steps parents took before arriving in their courtroom, and the MIAM certificate is the first thing they check. Beyond the legal requirement, demonstrating that you tried to resolve matters outside court — and that you did so in good faith — strengthens your position if the case does proceed to a hearing.

If you're working through the mediation-to-court process and want a structured framework for building your parenting plan, the England Child Custody & Parenting Plan Guide walks through each stage — from preparing your MIAM position to structuring schedules that meet the court's welfare checklist requirements.
