A C100 is the form reference number used for making an “Application to the courts under section 8 of the Children Act 1989 for a child arrangements, prohibited steps, specific issue order or to vary or discharge or ask permission to make a section 8 order“, it official title.
Simply put, you can ask the court to consider an application that relates to you child or grandchildren. It can be about contact arrangements, especially where you and your ex-partner are unable to agree on how to divide time with either parent. It can also be used to try and stop one parent from doing something, that they believe may not be in the child’s best interest, such as leave the country. It can also be used to ask the court to rule on a specific issue, this could be related to medical decisions or education and religion. It can also be used to vary an existing (court) order or have discharged totally.
For the most part, C100 forms are predominantly used when parents of children cannot agree on contact or living arrangements. A parent must complete the form and briefly explain to the court why they are making an application. Before an application is processed by the Family Court, it expects parents to attempt to mediate with each other to reach agreement together. The hope is that as a result a court application is no longer needed.
