Parent reviewing a C100 court application form

Your guide to making a child arrangements application to the court

APPLYING FOR A C100 FORM?

Applying to court can feel daunting, but you don't have to navigate it alone. We're here to help you understand the

process and the steps you need to take.

Am I Applying For The Right Order?

Child Arrangements Order

Child Arrangements Order

Decides who a child lives with, how time is spent with each parent and other important aspects of their care.

Prohibited Steps Order

Prohibited Steps Order

Stops a parent from taking

a specific action, such as

moving the child to another area or changing schools.

Specific Issue Order

Specific Issue Order

Decides a particular issue

relating to the child, such as

education, healthcare or religious upbringing.

A mediator can provide general information about mediation and the different options available, but cannot advise you which court order to apply for. If you are unsure which application is appropriate for your circumstances, you should obtain independent legal advice.

Where Can You Find The C100 Application?

Apply for a C100 online

Apply Online: The C100 app allows you to fill in the form digitally, save your progress, and return to it as needed.

Download and print the C100 form

Download and Print: The form is available for download here. If you're filling it out manually, we recommend printing multiple copies and completing a draft in pencil to allow for edits as you work through the form.

Do I Need A MIAM First?

In most cases, yes. Before the court will consider your C100 application, you are normally required to attend a Mediation Information and Assessment Meeting (MIAM).

The MIAM gives you information about mediation and other ways to resolve disputes. 

If mediation isn't suitable, your mediator can give you a MIAM certificate which is usually needed to apply to court.

There are exceptions. You may be exempt if there has been domestic abuse or child protection concerns. 

Before You Submit Your C100

Use this checklist to make sure you are ready:

​✔ I have attended a MIAM or qualify for an exemption.

✔ I know exactly what orders I am asking the court to make.

✔ I have considered whether mediation could help.

I have gathered the information I need for the application.

✔ I understand the court fee and fee remission options.

✔ I am ready to complete the C100 form.
