C100 Application
What is this? The C100 form is the court application you use to ask a family judge to make decisions about where a child should live, who they should spend time with, and any other arrangements concerning the child’s upbringing. What happens in practice?
1. You fill in the C100 – provide details about yourself, the child, the other parent or carer, and what orders you are seeking (e.g., a “child arrangements order” for residence or contact).
2. You attach any required documents – usually a copy of the child’s birth certificate, a statement of your case (often called a “position statement”), and, if relevant, any evidence of risk (such as police reports or medical notes).
3. You pay the court fee (or apply for a fee exemption if you’re on a low income or receiving certain benefits).
4. You submit the form – either online via the HM Courts & Tribunals Service portal, by post to your local family court, or in person at the court office.
5. The court issues a notice – you’ll receive a copy of the stamped application and a date for the first hearing (often called a “First Directions Appointment” or FDA).
6. The other party is served – the court sends them a copy of your application and they have a chance to respond (usually by filing a “C1A” response form).
7. You prepare for the hearing – gather any additional evidence, think about what you want to say, and consider whether you need mediation or a CAFCASS officer’s report.
8. At the hearing – the judge will listen to both sides, may ask questions, and will decide on next steps (such as ordering a CAFCASS report, setting a timetable for further hearings, or making an interim order).
What do I need to do? - Read the guidance notes that come with the C100 form (available on GOV.UK) – they explain each section clearly. - Be accurate and concise when describing the child’s current situation and what you want the court to decide. - Include any safety concerns clearly; if you fear harm, mention it and attach supporting evidence. - Check the fee – if you cannot afford it, fill out the EX160 fee‑remission form and submit it with your C100. - Keep copies of everything you send to the court and any receipts for postage or fees. - Note the hearing date once you receive it and make sure you can attend (or arrange for a representative if you cannot). - Consider mediation first – the court may expect you to have tried family mediation unless there are safety issues; a Mediator Information and Assessment Meeting (MIAM) is often required before proceeding. - Stay calm and focused on the child’s best interests; the judge’s priority is the child’s welfare.
