The N1A notes follow the order in which the form asks for information, and say to use black ink and block capitals if you fill it in by hand.
Heading. Name the court where you want the claim issued. For a money-only claim to proceed in the County Court, the notes say to enter "County Court Money Claims Centre".
Claimant and defendant. You are the claimant, and the person you are suing is the defendant. The notes ask for each party's full address including postcode, and say a missing postcode needs the judge's permission before the claim can be served. They give naming examples for individuals, partnerships, registered companies and others.
Brief details of claim. A concise statement of the nature of the claim and the remedy sought, for example payment of money.
Value. For a fixed ("specified") amount, the notes say to write it in the "amount claimed" box. For an unspecified amount, they give wording starting "I expect to recover", with three bands: not more than £10,000; more than £10,000 but not more than £25,000; more than £25,000. They also give wording for a claim you cannot value, and for some personal injury and housing disrepair claims.
Preferred court. The form asks for your preferred County Court hearing centre. The notes say the court takes it into account if a transfer is needed.
Defendant's name and address. One claim form is needed for each defendant. The notes say serving outside the UK or the rest of the European Economic Area may need the court's permission.
Vulnerability. The form asks whether you or a witness are vulnerable in any way the court needs to consider, and what support you want considered.
Human Rights Act. A Yes or No question on whether the claim includes issues under the Human Rights Act 1998.
Legal representative's costs. The notes say these fixed sums may only be claimed where a legal representative was instructed to make the claim.
Particulars of claim. Tick whether they are attached or to follow. The notes list a concise statement of facts, details of any interest, and anything else the relevant practice direction requires.
Statement of truth. The notes say it must be signed by you, your solicitor or your litigation friend, and name who signs for a registered company or corporation.
Address for documents. The claimant's or legal representative's address for documents, with optional phone, DX number, reference and email.
Copies. The notes say to keep one copy, and provide one for the court and one for each defendant.
