Child arrangements and C100: practical preparation

Identify the application and current guidance

The official C100 page covers child arrangements, prohibited steps and specific issue orders, including changing or ending an existing order. It links to the online application route and current paper form. Whether an application is appropriate, and whether permission is required, depends on the circumstances.

Check the MIAM requirement

Before many family court applications, attendance at a MIAM is required unless a valid exemption applies. A MIAM explains mediation and other ways to resolve the dispute. Use the current official guidance for the exemption categories and evidence, rather than assuming a past exemption still applies.

Raise urgent concerns or domestic abuse with an appropriate adviser. The application process includes questions about safety and confidential details; follow those instructions carefully.

Gather the right documents

• Current orders and details of related proceedings.
• The information about the children and other parties requested by the form.
• MIAM details or evidence relevant to an exemption.
• A record of relevant dates and any hearing or response deadline.
• The applicable court fee or Help with Fees information.

What happens after applying

Follow the communications and directions from the court and any professionals involved. Keep contact details up to date through the appropriate official channel. A published average for the wider family justice area cannot tell you how long your own application will take.
