The C100 Form Explained Through My Own Court Application Journey What the C100 Form really involves, explained simply for parents considering court. When I first heard I needed to complete a C100 Form, I felt overwhelmed. I wasn’t trying to start a legal battle. I simply wanted clarity about arrangements for my child. But the moment court was mentioned, everything felt formal, serious and slightly intimidating. If you are here because you are considering submitting a Form C100, you are in the right place. In this article, I will walk you through the form section by section, sharing what I learned along the way, and where mediation could have helped. First Things First: What Is a C100 Form? The C100 Form is the application you submit to the Family Court in England and Wales when you are asking a judge to make a decision about child arrangements. That might include: ● Where a child lives ● When a child spends time with each parent ● Specific issues (such as schooling or medical decisions) ● Prohibited steps (preventing certain actions) Before I even started filling it in, I had to understand one key point: in most cases, you must attend a MIAM (Mediation Information and Assessment Meeting) before applying to court. Section 1: Applicant and Respondent Details The first part of the Form C100 asks for: ● My details (the applicant) ● The other parent’s details (the respondent) ● Information about legal representation It sounds simple. But accuracy matters. Incorrect addresses can delay proceedings. I remember double checking everything. Court paperwork is not something you want returned because of a spelling mistake. Section 2: Details About the Children This section asks for: ● The child’s full name ● Date of birth ● Gender ● Current living arrangements It felt strange reducing my child’s life to a few boxes. But this section helps the court understand the basics quickly. The court’s priority is the child’s welfare. This principle was established in Re C (A Minor) (Residence Order: Shared Residence Order), where the court reinforced that decisions must focus on the child’s best interests. Section 3: What Order Are You Asking For? This is where the C100 Form becomes very specific. The court is asking you to clearly explain what you want it to decide. That might be: ● A Child Arrangements Order (for example, where your child lives or how time is shared) ● A Specific Issue Order (such as schooling or medical treatment) ● A Prohibited Steps Order (to prevent a particular action being taken) When I reached this section, I realised how important clarity is. The court cannot guess what outcome you are hoping for. You need to set it out in simple, direct terms. It is also worth checking whether you are legally entitled to make the application in the first place. You can read more about who can apply for a C100 Form before submitting your paperwork. Completing this section forces you to think carefully. Are you asking the court to decide every detail? Or just one specific issue? The more focused your application, the easier it is for the court to understand what is being requested. Section 4: MIAM Attendance This was a key moment in my journey. The form requires confirmation that you have attended a MIAM unless you qualify for an exemption (for example, domestic abuse or urgency). A MIAM is not mediation itself. It is an information and assessment meeting to explore whether mediation is suitable. Under the Children and Families Act, attending a MIAM is generally required before issuing a C100 Form. I had not realised how structured this requirement was. The mediator signs the MIAM section within the form to confirm attendance or exemption. At this point, I genuinely paused. Was court my only option? Section 5: Allegations of Harm (If Applicable) This section asks whether there has been: ● Domestic abuse ● Emotional harm ● Physical harm ● Risk to the child If you tick “yes”, you must complete additional details. This is one of the most sensitive parts of the Form C100. It is important to be factual and clear. Avoid emotional language. The court needs evidence based concerns. If safeguarding is raised, the court may order a CAFCASS report before the first hearing. Section 6: Why Court? Have You Tried to Resolve This? This section felt almost reflective. The court asks what steps have already been taken to resolve matters. Mediation? Direct discussions? Solicitors’ letters? When I reached this part of the C100 Form, I had to be honest about what we had actually tried. Had we really exhausted every option? Or had communication simply broken down? It was during this stage that I came across Mediate UK while researching alternatives online. I had been looking for information about the MIAM requirement and practical ways to resolve arrangements without going through a full court process. That is when I realised mediation was not just a formality, it was a genuine opportunity to reach an agreement. This section of the form encourages you to show the court that you have made reasonable efforts to resolve the dispute. Judges want to see that court is not being used as a first step, but as a last resort. For many parents, mediation provides a structured environment to have difficult conversations safely and constructively. And for me, learning about it at this stage made me pause and reconsider whether a court order was truly necessary. What Happens After You Submit the C100 Form? Here’s what I learned: 1. The court issues the application. 2. CAFCASS carries out safeguarding checks. 3. You attend a First Hearing Dispute Resolution Appointment (FHDRA). 4. The judge explores whether agreement is possible. If agreement is not reached, the case may move towards further hearings or even a final hearing. It can take months. Sometimes longer. Court is structured and formal. For some families, it is necessary. But it is rarely quick. What I Wish I Had Known Before Filing a Form C100 Looking back, I wish I had understood: ● Court should usually be a last step, not the first. ● Mediation is faster and more cost-effective. ● Agreements reached in mediation can still be formalised. ● The language you use in the application matters. The process is not designed to punish parents. It is designed to focus on children. But it can still feel stressful. Practical Tips If You Are Completing a C100 Form ● Take your time. ● Be clear and factual. ● Gather relevant documents before starting. ● Attend a MIAM even - if you think mediation will not work. ● Seek legal advice if unsure. Most importantly, ask yourself whether direct discussion, with professional support, could resolve matters before court becomes involved. Final Thought Completing a C100 Form can feel like a significant step. It signals that informal discussions may not have worked and that you are asking the court to step in. That can feel daunting. Before submitting your application, it can help to fully understand what the form involves and what the court process may look like afterwards. Reading a detailed guide to completing a C100 form can clarify what each section means and what information you will need. Taking time to prepare properly can make the process feel more manageable. And whatever stage you are at, focusing on practical, child-centred solutions will always place you in the strongest position moving forward.
