N1 Claim Form: How to Complete and File It Without Costly Mistakes

The N1 claim form is used to start many civil claims under CPR Part 7 in England and Wales. Small errors can cause delay, extra fees or problems with service and enforcement. 

This guide explains how to complete each section, name the right defendant, write clear particulars of claim and calculate interest. It covers 2025 court fees, copy requirements and the correct filing route. You will see a practical £2,400 example and the mistakes to check before signing. The form starts the case. The court decides later whether it belongs on the small claims track. That distinction prevents costly assumptions.

What is an N1 claim form?

The official N1 claim form is titled Claim form (CPR Part 7). A claimant uses this claim form to ask the court for a remedy. The defendant is the person or body said to be liable.

The form records the parties, addresses, claim summary, value, amount, fee and statement of truth. People search for N1 form, form N1, claim form N1 and N1 court form. Each term points to the same official document. The phrases N1 form UK and form N1 claim form mean the England and Wales version.

The N1 is not a dedicated small claims application form. Nor is it one of several interchangeable small claims court forms. A small claims form N1 starts a Part 7 case that can later reach the small claims track.

CPR 26.9 sets £10,000 as the normal ceiling for most such cases. The court still considers value, complexity and other factors at allocation. CPR Part 26 sets out the track rules.

Key point: A small claims court N1 form does not secure small-claims allocation at issue. It starts the county court claim. CaseCraft.AI is built for small claims within the usual £10,000 ceiling.

Should you use Form N1 or make the claim online?

Use the paper form where the official online route does not fit the claim. Some civil money claims for a fixed sum can start online. An unknown amount needs paper filing. Check the service rules before choosing.

Can I complete an N1 form online? You can type into the official PDF, save it, print it and file it by the permitted route. Some eligible civil money claims can start through the government’s separate online service. That is not the same as emailing a completed paper form.

Is the N1 form the same as a small claims form? No. The N1 form in the UK starts a wider class of Part 7 proceedings. Small claims forms used later serve different tasks. Use the latest official N1 claim form and N1A notes.

Before you complete the N1 claim form

Do the groundwork first. It is faster than fixing a faulty County Court claim form after issue.

• Read the protocol for your dispute. Follow the pre-action requirements that apply. Check them against the official Pre-Action Conduct Practice Direction.
• Send a letter before action with the facts, sum and reply date.
• Check the defendant’s full legal name and service address.
• Fix the legal basis. List the duty, breach, loss and remedy.
• Total the principal sum. Treat interest and court fees as separate items.
• Gather the documents needed to file a claim.
• Check the limitation date. Do not wait for the final day.
• Download the current form and notes. Recheck the filing address and fee.

Contracts, invoices, emails and photos are evidence. The particulars of claim state the material facts and the basis for relief. They are not an evidence bundle.

How to complete an N1 claim form, section by section

Start with exact identity and clean arithmetic. Then write a short claim narrative. This is the practical answer to how to complete an N1 claim form and how to fill in an N1 claim form.

1. Enter the court and party details correctly

Use each person’s full name, address and postcode. For a sole trader, name the person and the trading style. For a registered company, use its full registered name.

The official Practice Direction 16 gives these party-name rules. It says a form without full addresses and postcodes can be retained and not served.

Check the registered company record and the service address. A wrong defendant can make a judgment hard to enforce. One letter can change the legal target. “Oak Repairs” can be a brand. “Asha Khan trading as Oak Repairs” names the person.

This check matters for every county court claim and every county court claim form. Read more on taking someone to small claims court before naming several parties.

2. Write the brief details of the claim

Give the court a compact map. State the agreement or duty, the key breach, the sum and the remedy.

CPR 16.2 requires a concise account of the claim’s nature and the remedy sought. It does not call for a witness statement.

Fictional N1 claim form completed example.

The claimant seeks £2,400 for building work completed under a written agreement dated 12 March 2025. The defendant failed to pay invoice 482 by 9 April 2025. The claimant sent a letter before action on 6 May 2025 and claims the unpaid sum, interest and the court fee.

Adapt this N1 claim form completed example to the real facts. Do not copy facts, dates or wording that do not fit.

3. State the value of the claim

State the value in the form’s terms. Keep four figures distinct:

• Principal, such as an unpaid £2,400 invoice.
• Interest accrued to the issue date.
• The issue fee.
• Any recoverable legal costs with a stated basis.

CPR 16.3 asks a money claimant to state the sum or expected recovery band. A £2,400 principal plus £40 interest has a £2,440 claim value for the issue fee. The £115 paper fee then produces a £2,555 total shown in the amount box. CPR Part 16 gives the value and content rules.

Do not reduce a genuine figure to enter a lower band. Do not add a round amount for upset or time with no legal basis.

4. Draft the particulars of claim

The particulars of claim should state the facts that create liability. Use dates, numbered paragraphs and time order.

CPR particulars of claim must include a concise statement of the relied-on facts. CPR 16.4 requires the basis and detail of any interest claim.

Answer nine points:

1. Who made the agreement, or owed the duty?
2. What did each side agree to do?
3. What did the claimant do?
4. What date applied to performance or payment?
5. What act or omission formed the breach?
6. What loss followed?
7. How was each sum calculated?
8. What remedy does the claimant seek?
9. What is the legal or contractual basis for interest?

Fictional particulars of claim template UK structure

1. On 12 March 2025, the claimant agreed in writing to repair the defendant’s shop roof for £2,400.
2. The claimant completed the agreed work on 26 March 2025.
3. Invoice 482 required payment by 9 April 2025.
4. The defendant paid nothing and gave no defect notice.
5. The claimant sent a letter before action on 6 May 2025.
6. The claimant claims £2,400, interest on the stated basis and the court fee.

This UK particulars of claim template shows structure, not a universal pleading. A consumer sale, faulty service, loan or negligence case needs different facts.

The particulars of claim form can be the box on N1 or separate pages served under the rules. Label any attached particulars of claim form with the parties and claim details.

The Part 7 claim form can state that particulars will follow. CPR 7.4 then controls timing. In many small claims, a clear claim form N1 can include them at issue. Read the current CPR Part 7 timing rules before choosing separate service.

5. Calculate the amount and interest

State the principal first. Then name the contract, statute or other basis for interest. Give the percentage, start date, end date, accrued sum and daily rate where required.

How to calculate interest on an N1 claim form depends on the legal basis. GOV.UK says the usual rate for many non-commercial debts is 8%. It gives this method: principal × 0.08 ÷ 365.

A £2,400 debt creates a daily rate of about £0.526. For 76 days, that is about £39.98. Check the official interest method.

Do not apply 8% by reflex. Late commercial payments and contract terms can use other rules. This is why how to calculate interest on an N1 claim form starts with the legal basis, not a calculator.

6. Add the court fee and total

For a paper money claim in 2025, the issue fee depended on the claim amount plus interest. These were the official bands.

How much does it cost to file an N1 form? A £2,440 claim costs £115 to issue on paper in 2025. A £6,200 claim cost £455.

A later hearing fee or application fee can arise. Fee help can reduce or remove an issue fee for an eligible person. Check the live fee page on filing day.

7. Sign the statement of truth

Use the exact statement of truth printed on the current form. Do not edit it. Sign, date and state the signatory’s capacity where the form asks. A company officer or legal representative must identify that role.

CPR Part 22 requires a statement of case to be verified. A missing statement of truth can restrict reliance on the claim. A knowingly false statement can lead to contempt proceedings. Read the official statement of truth rules.

The same care applies to the N1 court form and any attached CPR particulars of claim. Check every name and figure before signing the statement of truth.

How many copies do you need and where do you file Form N1?

For paper filing, make one copy for the court, one for your records and one for each defendant. The N1A notes state this copy rule.

Where to send an N1 claim form depends on the remedy. The 2025 N1A notes direct a money claim to:

Civil National Business Centre
St Katharine’s House
21–27 St Katharine’s Street
Northampton
NN1 2LH

Check the official N1A notes on posting day. A non-money claim can have a different filing place.

How many copies of an N1 claim form do I need? With one defendant, prepare three complete sets. With two defendants, prepare four. Keep proof of posting and a full copy.

Do not assume the same service of claim form process applies to every case.

How to file a claim in small claims court starts with issue, not track allocation. For this paper route, check the form, attach any separate pleading, pay the fee and send the copies to the stated place.

The court handles service in many cases. Its directions control serving a claim form. Follow any different direction it gives.

People ask, “How do I file a claim in small claims court?” First, complete pre-action work. Then pick the valid issue route, pay the right fee and retain proof. This is the short answer to how to file small claims using paper.

What happens after filing an N1 claim form?

The court checks the filing, issues the claim and arranges service under the applicable process. The defendant can pay, admit, defend or acknowledge service. The court then gives the next directions.

1. The court issues a sealed claim form.
2. Service of the claim form starts the response timetable.
3. The defendant replies or risks default judgment.
4. A defended case moves through directions and track allocation.
5. A defended eligible money claim worth £10,000 or less normally goes to mandatory mediation under the 2025 N1A process.
6. The court lists a hearing where settlement does not end the case.

CPR Part 6 governs service. CPR Part 7 deals with timing for serving a claim form and any separate particulars.

Read how a defendant can respond and the deadline for responding to a claim.

What happens after filing an N1 claim form? Watch for the notice of issue, record the service date and follow each court direction.

A claim of £10,000 or less is normally suited to the small claims track. It is not treated that way just from the label small claims court N1 form.

Costly N1 claim form mistakes to avoid

Most faults are plain. Each one can still cost time, a fee or a fair chance to present the case.

• Naming a shop sign, not its owner or registered company.
• Giving no full postcode for a claimant or defendant.
• Turning brief details into a long witness statement.
• Treating evidence as the particulars of claim.
• Omitting the agreed terms, breach date or loss calculation.
• Using a generic particulars of claim template UK with the wrong facts.
• Claiming interest with no stated basis or calculation.
• Paying an old court fee.
• Altering the statement of truth.
• Filing too few sets of the claim form Part 7.
• Sending the form to an old address.
• Ignoring a relevant pre-action protocol or limitation date.
• Treating all small claims court forms as a small claims application form.
• Assuming the small claims form N1 guarantees track allocation.

Can I correct a mistake on an N1 claim form? Correct it before issue and initial the clean amendment where the form permits.
