Form N434: Notice of Change of Legal Representative — Act in Person or Change Solicitor (2026 Guide)

Form N434: Notice of Change of Legal Representative — Act in Person or Change Solicitor (2026 Guide)

Every case before the civil courts has a record of who conducts it for each party — a solicitor, or the party themselves — and an address for service where documents about the claim must be sent. When that changes, the court and the other parties are entitled to know, and the Civil Procedure Rules require you to tell them formally. Form N434, the notice of change of legal representative, is how you do it.

For a litigant in person, this small form often marks a significant moment: the point at which you take over the conduct of your own case. You are fully entitled to do that — a party may conduct their case in person at any stage — and the N434 is how you start properly, on the record, with everything coming to you.

This guide explains when the notice is needed, what the form asks for, how to file and serve it, and what changes once it takes effect.

When Do You Need Form N434?

Under CPR 42.2, a notice of change is needed in three situations:

Your legal representative has ceased to act and you will now act in person. This is the most common situation for eLitigant readers. Perhaps the firm has come off the record, perhaps funding has run out, or perhaps you have simply decided to conduct the case yourself. You tick box A on the form, give your own address for service, and take over.

You have appointed a legal representative after acting in person. The notice tells the court and the other parties that a named firm now acts for you, and that documents should go to that firm’s address.

You are changing from one legal representative to another. The new firm will normally complete and file the notice for you — GOV.UK confirms that where you have appointed or changed a legal representative, they complete the form. You should still check it has actually been filed and served.

You do not need Form N434 when:

• You have conducted the case in person from the start — there is no change to record.
• Proceedings have not yet been issued — there is no court record to update.
• You want to settle the case by agreement — that is a consent order, a different thing entirely.
• You want to withdraw your claim — that is a notice of discontinuance (Form N279).
• You want the court to make an order — that is an application notice (Form N244).

Why the Notice Matters

The rule that gives the notice its force is CPR 42.1: until the notice of change is filed and served (or the court orders otherwise), the solicitor on the record is treated as still acting, and their business address remains your address for service. In practical terms:

• Orders, hearing notices and the other side’s documents will keep going to the former solicitor’s address.
• Deadlines run whether or not the documents ever reach you.
• The other parties are entitled to treat service at the old address as good service.

That is why the notice is filed and served promptly, not left until something goes wrong. Taking over your own case starts with making sure everything about the case now comes to you.

What the Form Asks For

Form N434 is short — a single form with tick boxes. It asks for:

• The heading details — the court dealing with the claim, the claim number, and the names of the claimant and defendant.
• Box A — tick this if your legal representative (named, with their address) has ceased to act for you and you will now be acting in person.
• Box B — tick this if a new legal representative (named) has been instructed to act for you, in place of the previous one (named, with their address).
• Box C — the certificate that you have served notice of the change on every party to the claim, and on the former legal representative. You tick either A or B, and always C.
• Your new address for service — the address to which all documents about the claim should now be sent, with postcode, and your telephone number, e-mail address and any reference.
• Signature and date — signed by you (or the new legal representative, where box B applies).

Step-by-Step: How to Complete and File Form N434

Step 1: Complete the Form

Download the current form from GOV.UK (linked at the top of this page), fill in the heading details exactly as they appear on the claim, and tick box A or box B as appropriate. Name the former legal representative and give their address, and state clearly the date from which the change takes effect.

Step 2: Give a Reliable Address for Service

If you are going to act in person, your address for service will normally be your home address. It must be an address where documents will genuinely reach you, and you must keep an eye on it — everything about the case will now arrive there. Adding your e-mail address and phone number helps the court contact you quickly. If your address changes later in the case, tell the court and the other parties in writing straight away.

Step 3: File the Notice at Court

File the completed form at the court dealing with your claim — by post, or by e-mail where the court has published an e-mail filing address. Quote the claim number in any covering letter. There is no court fee for filing a notice of change.

Step 4: Serve a Copy on Every Other Party

CPR 42.2 requires you to serve notice of the change on every other party to the claim — and, where there was a legal representative before, on that former representative too. Send each of them a copy of the completed form with a short covering letter. Box C on the form is your certificate that this has been done, so complete the service before (or at the same time as) you file.

Step 5: Keep Evidence, and Diary Everything

Keep copies of the form, the covering letters and proof of posting. Then go through the case and diary every live deadline — directions, hearing dates, filing dates. From the moment the notice takes effect, meeting those deadlines is in your hands, which is exactly where you decided to put it.

Key Points at a Glance

What Happens After the Notice Is Filed

Once the notice is filed and served, the court record is updated. All future orders, notices and documents in the claim come to your new address for service. If you are now acting in person, you deal directly with the court and the other parties: you file your own documents, you receive theirs, and you appear at hearings yourself.

If you later instruct a solicitor again, a fresh notice of change is filed at that point — the form works in both directions.

There are also two situations dealt with by court order rather than by this form. Under CPR 42.3, a solicitor who wishes to come off the record (for example where the retainer has ended but the client has not filed a notice) may apply to the court for an order declaring that they have ceased to act. Under CPR 42.4, another party may apply for an order removing a solicitor from the record where that solicitor has died, become bankrupt, ceased to practise or cannot be found. In both cases the order, once made and served, has the same effect as a notice of change.

Common Mistakes to Avoid

1. Filing at court but not serving the parties (or the other way round). The rule requires both. Box C is a certificate of service — complete the service, then file.

2. Forgetting the former legal representative. Where a solicitor was acting, they must be served with the notice too. They need to know they are off the record.

3. Giving an address you do not monitor. Everything about the case will go to the address on the form. A rarely-checked address means missed documents and missed deadlines.

4. Assuming the court notifies everyone for you. It does not. Serving the other parties is your job, and the form makes you certify you have done it.

5. Confusing the N434 with other forms. The N434 changes who conducts the case — nothing else. Settling by agreement is a consent order; ending your claim is a notice of discontinuance; asking the court to do something is an application notice.

6. Delay. Every week the notice goes unfiled is a week of documents going to an address that is no longer looking after your case. File it as soon as the change happens.

7. Not signing and dating the form. An unsigned notice will be returned, and the old record stands in the meantime.

How Chris Can Help

The N434 itself is a short form — the significance is the moment it marks. If your solicitor has come off the record, you are not just filling in a tick-box: you are taking over a live case, with directions to meet, documents to produce and perhaps a hearing ahead.

Chris, your document assistant at eLitigant, helps you complete the notice and drafts the covering letters — to the court, to the other parties and to the former solicitor — to a professional standard. More importantly, Chris helps with what comes next: understanding where your case stands, and preparing the documents the case actually needs from here, whether that is a witness statement, an application or correspondence with the other side. Thousands of people conduct their own cases every year; the point of eLitigant is that doing so should never mean doing it to a lower standard.

Frequently asked questions

What is Form N434 used for?

Form N434 is the notice of change of legal representative. It tells the court and every other party who now conducts your case and the address to which documents about the claim must be sent — when your solicitor stops acting and you act in person, when you appoint a solicitor after acting in person, or when you switch firms.

Do I need it to represent myself?

If a solicitor has been acting for you on the record, yes — you file and serve an N434 stating that you will now act in person and giving your own address for service. You are fully entitled to conduct your case yourself; the notice simply puts the change on the record so everything comes to you. If you have acted in person from the start, no notice is needed.

Is there a court fee for filing Form N434?

No. Filing a notice of change of legal representative is free. You file the form at the court dealing with your claim and serve a copy on every other party (and the former legal representative, where there is one).

Who do I have to send the notice to?

The court dealing with the claim, every other party to the claim, and — where a legal representative was acting before the change — that former representative. Box C on the form is your certificate that the other parties and the former representative have been served.

What happens if I don’t file it?

Under CPR 42.1 the former solicitor is treated as still acting until the notice is filed and served, so documents keep going to their address and deadlines run whether or not you ever see the papers. File the notice as soon as the change happens.

Can I use Form N434 to settle my case?

No. Form N434 only changes who conducts the case. A settlement reached by agreement is recorded in a consent order, which is a different document with its own procedure.
