FL407 form: ask for a warrant of arrest after a protection order is broken

Form FL407 is the application for a warrant of arrest under section 47(8) of the Family Law Act 1996. It is used by the person protected by a non-molestation order, an occupation order or an undertaking, when they believe the respondent has broken it.

Time and money

On your own: A day or more
With Wren: About an hour for most forms
Solicitor for this form: £740 to £1,2403 to 5 hours

A solicitor’s time for the FL407 can run to £1,240. With Wren it is part of £19.99 a month, and it takes about an hour for most forms rather than a day or more.

Times and hours are Wren’s estimates for a typical case, not quotes. Solicitor costs are those hours at £247 an hour, the courts’ guideline rate for a solicitor with over four years’ experience, outside London (GOV.UK, Solicitors' guideline hourly rates (in effect from 1 January 2026)). The guideline runs from £200 to £295 an hour outside London depending on experience, firms set their own rates, and VAT is added on top.

Who uses the FL407

The applicant: the person the order or undertaking protects. The respondent is the person who has to follow the order and who would be arrested. If you are in immediate danger, call 999.

When it is used

After the court has made an order or accepted an undertaking, and you believe the respondent has failed to comply with it. For an occupation order, it is used where no power of arrest was attached to the order, or one was attached only to some of its provisions.

Before you start

The order, or the record of the undertaking, with the court name, the case number and the date.
The paragraph numbers of the order, or the parts of the undertaking, that you say were broken.
For each breach: the date, the time if you know it, where it happened and what the respondent did or said.
Any record of the breaches you have, such as messages, photographs or a police reference number.

How to fill in the FL407

Open each part for what it asks and how to answer it. In Wren, each part is a few plain questions, and your answers fill in the form.

The heading

You give the court, the case number, and the names of the applicant and the respondent, copied from the order.

The order or undertaking

You give the date the court made the order or the respondent gave the undertaking, and list the parts of it that are relevant.

The names

You give your own name as the applicant and the name of the respondent, the person to be arrested.

The breach

You list the ways the respondent has disobeyed the order or broken the undertaking. Keep to facts you can confirm on oath, with dates and places.

Signing and swearing

The form ends with your application for a warrant, which you sign and date. The application has to be substantiated on oath, which means swearing or affirming it before a court officer or another person authorised to take oaths. Ask the court office how it wants this done.

Wren Family turns official forms into short, plain-English questions you can answer at your own pace. You check everything before you send it: nothing goes to the court for you.

Get started

Free for 14 days, no card. Then £19.99 a month, with your money back within 14 days if it’s not right.

What happens after you send it

The court decides whether to issue a warrant. It issues one only if the application is substantiated on oath and it has reasonable grounds to believe the respondent has failed to comply with the order. If the respondent is brought before the court under a warrant and the matter is not dealt with straight away, the court may remand them. Once Form FL407 is in your Forms list, Wren can help you prepare it. Wren does not file, serve or send anything, and it does not swear or affirm the application for you.

Common mistakes

Signing the form before it is sworn or affirmed. Ask the court office how it wants this done first.
Describing the breach in general terms. Give the date, the place and what was done for each breach.
Not saying which parts of the order or undertaking were broken.
Using this form where the order already has a power of arrest on the provisions broken. The police can arrest without a warrant in that case.

Common questions

Can I call the police instead?

If you are in immediate danger, call 999. Breaking a non-molestation order without reasonable excuse is a criminal offence, so you can report it to the police. The same conduct cannot be punished both as a criminal offence and as a contempt of court.

Does the FL407 have to be sworn?

Yes. The law says a warrant will not be issued unless the application is substantiated on oath. Wren does not swear or affirm the application for you.

Can I use FL407 if the respondent broke an undertaking?

The form covers orders and undertakings. An undertaking given to the court is enforceable as if the court had made an order in the same terms.
