Completing the C100 form can seem like a daunting task and can lead to many questions. It’s in your interest to make sure your C100 court form is as complete as possible before you send it off to court, so we’ve written comprehensive instructions on how to complete a C100 application, as well as providing images to illustrate a completed C100 court form.

If you are looking to find out how to complete a C100 application you are in the right place, but if you would like to know the types of orders you can obtain through a C100 application please visit here.

If you want to know how to complete a C100 application, here is the process.

You may wish to get your own legal advice and use an experienced family solicitor. This resource does not constitute legal advice, it is for informational purposes only.

A C100 court form is used to ask the court to make or amend a child arrangements order. You can download the form here. If you don’t have a printer, you can ask the people at the family court for the form or complete the C100 online. You can also contact Support Through Court, an organisation set up to support individuals who will represent themselves through the court process (also known as litigants in person). Here is a link to our resource that will provide more information about them.

You must attend a mediation information assessment meeting before attending family court, also known as a MIAM. Attending a MIAM became a legal requirement in 2014. Usually, when family mediation isn’t considered suitable, or a party has decided they do not wish to continue with family mediation, the party would complete their C100 application to the family court. However, there are instances where the courts will defer parties back to family mediation. A MIAM can only be provided by a Family Mediation Council Accredited Family Mediator.

A MIAM is the session you will have on your own before you and the mediator decide whether to invite the other party to a MIAM. If the other party completes their MIAM and the family mediator and both parties agree to proceed, a family mediation session will then take place.

In the MIAM, the family mediator will:

  • Provide you with information about the mediation process
  • Explore what you want to resolve
  • Provide you with relevant legal information
  • Assess the suitability of a potential mediation
  • Find out more about your situation from your perspective
  • Answer any questions you may have.

Book your MIAM HERE.

Family Law Mediation

To sign the C100 form, the family mediator must be Family Mediation Council accredited. This means that the mediator has several years of experience and has completed an FMC-recognised family mediation course. The mediator will have also completed an entire mediation portfolio and kept their training and membership to date in line with the Family Mediation Council.

The family mediator will sign page 9 and date the form, ticking only the boxes they consider relevant to your situation and return it to you. You must request the signed C100 Form from your mediator and send it to the family court within four months after the date of your MIAM. Any later, and the courts will not accept it.

It costs £232 to submit the C100 form. If you receive certain benefits or hold a low income, you may be eligible for support with these fees. However, it will not cover your legal costs. This will not change how the family court will handle your case.

Please see below a copy of a completed C100 application form.

This is the first page of the C100 application form. You will need to read the information provided. It is recommended that you sign and date this page to confirm your understanding of the information.

Nature of application

Image Page 1 C100 Application Form General Information

Page 1  Details of your case/application

Make sure to enter your HWF Case Number in the upper-right-hand corner of your written application. You will only have a HWF Case Number if you are receiving help with the court fees. You are the applicant and will be asked to enter the respondent’s full name next.

You can use the C100 to apply for the following types of orders:

A child arrangements order: is an application to the court that asks a judge to decide how and when your children will spend time with you. A child arrangements order can cover holidays, school breaks, and home visits.

A prohibited steps order: There may be certain circumstances where a parent wishes to move a child out of the area or change the child’s school, and the court will have to consider whether it is in the child’s best interests for this to occur. Sometimes parents disagree about such matters. Anyone considering applying for permission to relocate a child from the area (or change their school) must seek independent legal advice first.

A specific issue order: is usually for matters where the parents cannot agree on children going on holiday, who will the passport stay with, Christmas arrangements and/or other special occasions, and which school the child/children will attend.

On the C100 application form, you can select more than one box and include a short description in the box.

Concerns about risk of harm

When making an allegation against a person, the court will investigate the allegation thoroughly. You need to provide clear details of your claims and supporting evidence. Where applicable, answer yes if the circumstance applies to you. You can fill in any extra detail on Form C1A and file it with the C100 form.

Additional information required – tick yes if the boxes apply to you and no if they don’t. Where they do apply, please complete the relevant sections stated.

Are you asking for permission to make this application, where that is required?

In relation to making a C100 court application, you would not need to ask the family court for permission if you have parental responsibility, where the child is of the family or if the child has lived with you for three or more years.

If you are a grandparent, and the child/children in question have lived with you for three out of the last five years, you can request a guardianship.

Is an urgent hearing or without notice hearing required?

An urgent hearing or a hearing without notice is only needed if the court needs to act quickly as a child is at immediate risk of harm or where the other party is likely to cause harm to the child. In this case, you would need to demonstrate to the court in this C100 court form the immediate risk to the child.

Are there previous or ongoing proceedings for the child(ren)?

Where there are other or previous applications/proceedings for the child/children, you would need to notify the court of this. You will need to tick yes and provide details in section 7.

Are you applying for an order to formalise an agreement (consent order)?

This is only applicable if you and the other party have agreed either between yourselves, through family mediation or via solicitors (not in court) and would like to formalise the agreement.

Is this a case with an international element or factors affecting litigation capacity?

If one of the parents or child/children lives abroad or is involved in moving abroad, please tick yes and complete sections 8 and 9. Do not tick this section if the issue is about taking children on holiday.

Will the child or any of the people involved need to use spoken or written Welsh during the course of the proceedings?

Please tick yes if this is the case and complete section 10.

Section 3b Child Protection Concerns

This section relates to whether a child is in police protection and is under a child protection plan or one is underway. You would usually be notified if this was the case.

Section 3c Urgency

This section relates to the urgency of the case. You will need to decide whether there is a MIAM exemption because if you state there is and the court disagrees, you will need to attend a MIAM.

The court would classify an urgent case as:

  • There is a risk to life and physical safety to application or home
  • There is a risk to the child
  • There is a risk of loss of evidence.

In this instance, where one of these would apply, and you are submitting an urgent court application, you will need to submit it the same day.
