Applying to the family court for child arrangements can be a daunting process. The C100 form is crucial for starting this legal journey, so understanding how to complete it accurately is vital. This guide will walk you through the form step-by-step, providing detailed explanations and tips to ensure your application is thorough and precise.
Understanding the C100 Form
The C100 form is used in England and Wales to apply to the family court for child arrangements, such as deciding where a child will live, contact arrangements, or other specific issues like schooling and holidays. This form can also be used for applying for prohibited steps orders and specific issue orders.
Types of Orders
- Child Arrangements Order: Determines where a child lives, who they spend time with, and when they see each parent.
- Prohibited Steps Order: Prevents one parent from making certain decisions about the child’s upbringing without the court’s consent.
- Specific Issue Order: Resolves specific disputes about the child’s upbringing, such as education or religious matters.
Before You Begin
Check Mediation Requirements
Before applying, you generally need to attend a Mediation Information and Assessment Meeting (MIAM) unless an exemption applies, such as cases involving domestic abuse or urgency. The mediator will sign the relevant section of your form if you’ve attended a MIAM.
Mediation Exemptions
- Domestic Abuse: If there is evidence of domestic abuse, you are exempt from attending a MIAM.
- Child Protection Concerns: If social services are involved due to child protection concerns, mediation may be bypassed.
- Urgency: If the situation requires immediate court intervention, you can skip the MIAM.
Gather Necessary Information
You’ll need the following information:
- Your details and those of the other parent(s)
- Child(ren)’s details
- Specific reasons for your application
- Details of any previous or ongoing court cases related to your family
- Evidence of mediation or exemption
