Why Has a C100 Been Issued When I Haven’t Attended Mediation?

We completely understand that receiving notice of a C100 court application can feel frustrating — even unfair — if you haven’t yet had the chance to attend a mediation assessment and information meeting, or MIAM, yourself.
Many people feel confused or upset that one person has been able to move forward to a court process without the other person’s involvement. This short guide explains why this happens and what it means for you.
What is a C100 form?
A C100 is the form used to apply to the Family Court about arrangements for children — for example, where they live, who they spend time with, or specific issues such as schooling or holidays.
Before most people can make this kind of application, they are required to attend a Mediation Information and Assessment Meeting (MIAM) with an accredited family mediator.
A MIAM is a confidential, one-to-one meeting (not joint mediation) where a family mediator explains:
How mediation works
How it might help you both reach an agreement without going to court
What other options and support might be available
It’s also an opportunity for the mediator to assess whether mediation is suitable and safe for everyone involved.
Why has a C100 been issued if I haven’t attended?
When one person attends a MIAM and requests the page of the c100 from the mediator, the Family Mediation Council’s Code of Practice and the Family Procedure Rules (Part 3) require the mediator to sign the relevant section of the C100 form confirming that a MIAM has taken place.
This step does not mean the mediator supports the application or that mediation is finished — it simply confirms that the applicant’s requirement to attend a MIAM has been met.
The mediator cannot withhold their signature once the MIAM has been completed and the applicant asks to proceed. Doing so would prevent that person from accessing the court, which would go against professional and procedural rules.
Does this mean I’ve lost my chance to mediate?
No — not at all.You still have the same opportunity to take part in mediation if you wish to. The court actively encourages families to try mediation at any stage, even after an application has been made.
You can contact us at any time to book your own MIAM or let us know you’d like to explore mediation before or during the court process.
Is the mediator supporting the other person?
No. Mediators are completely impartial. Generally each person is offered the opportunity to attend a MIAM, and information shared in one meeting remains confidential.The fact that one person attended first simply reflects how the process begins — not who is “favoured” or “believed”.
What happens next?
If you’ve received a copy of a C100 application, the court will contact you directly about the next steps.
In the meantime, you can:
Contact Pax Mediation to book your own MIAM or discuss mediation options
Take legal advice on your legal position
Remember that you can still reach an agreement through mediation at any point.
In summary
We know it can feel one-sided when a C100 is issued before you’ve been involved.However, the mediator’s actions are guided by the Family Mediation Council’s Code of Practice and the Family Procedure Rules — both of which require them to confirm when a MIAM has taken place if requested by the applicant.
This does not stop you from taking part in mediation, and the invitation remains open if you wish to explore this route.
