Quick Answer

What is the Purpose of a Form C1A?

Form C1A serves as a supplemental document in family law proceedings, particularly in applications for Child Arrangements Orders, Prohibited Steps Orders or Specific Issue Orders. Its primary purpose is to allow parties to detail allegations of harm or risk to a child or themselves. This includes incidents of domestic abuse, violence, or other harmful behaviours. By completing Form C1A, the court is provided with a clear understanding of the key issues at the heart of the application, enabling it to make informed decisions about case management and the welfare of the child.

When is a Form C1A Required?

A Form C1A must be completed by the applicant if they believe that the child has suffered or is at risk of suffering harm, including domestic abuse, violence, or other harmful conduct, and by the respondent if they allege harm in their Form C7, being the acknowledgment form following the issue of a Form C100 application.

How to Complete a Form C1A

Completing a Form C1A requires the applicant to provide detailed information about themselves and the child or children involved in the case, including detailing the nature and frequency of the alleged harm or abuse. It is important to focus on the most relevant incidents that form the basis of the case, and avoid including irrelevant or overly historical information.

Accuracy and completeness are crucial when filling out the form, as inconsistencies or omissions could cause delays or impact the court’s decision. The form also requires parties to disclose any involvement with external agencies, such as the police, social services, or healthcare providers, in relation to the allegations. This ensures that the court has access to all relevant information from the outset of the proceedings, and can assess the seriousness of the allegations, as well as the steps already taken to address them.

What Happens After Submitting a Form C1A?

Once the Form C1A has been completed and submitted, the court will carefully review the information provided as part of the overall application for a child arrangements order or other related orders. The court will consider the form alongside any other relevant documents and details that have been submitted. If the court believes that additional information is needed to make a fully informed decision, it may request further documentation from either party or schedule a hearing to
