How to Fill In Form 126A Northern Ireland

Form 126A is the document you return to the Civil Processing Centre when you want to dispute a small claim filed against you in Northern Ireland. Getting it wrong — or leaving fields blank that needed filling — can weaken your position before you ever reach a hearing. Here is what each section asks for and how to handle it.

What Form 126A Actually Is

Form 126A is the Notice of Dispute under Order 26 of the County Court Rules (Northern Ireland) 1981, as substituted by the 2002 amendment rules. It tells the court and the person suing you (the applicant) that you contest their claim, either in full or in part. Once the Civil Processing Centre at Laganside Courts in Belfast receives your completed 126A, the case file is transferred to the local County Court named on your Form 125 for a hearing.

You have 21 calendar days from receiving your small claims pack to get this form back to the CPC. If the 21st day falls on a weekend or bank holiday, the deadline extends to the next working day the court is open.

Walking Through Each Section

Your details. Fill in your full name, address, and a daytime contact number. If you have a solicitor acting for you, their details go here too — but most respondents in small claims represent themselves.

The defence grounds. This is the main text box and the part that matters most. Write a clear, factual summary of why you disagree with the claim. Stick to what happened, in date order if possible. You do not need legal jargon. A straightforward account — "I paid the full invoice on 3 March 2026 by bank transfer; the applicant's claim for the same sum is already settled" — is stronger than a vague denial.

Keep it specific. Name dates, amounts, and any documents you have. The District Judge reads this before the hearing, so it shapes their first understanding of your side.

Partial dispute. If you accept part of the claim but disagree with the rest, say so plainly in the defence box. For example: "I accept that £800 is owed for materials but dispute the £2,200 labour charge because the work was left unfinished." You are not locked into all-or-nothing.

The counterclaim section. If the applicant owes you money from the same dispute — say a contractor left your kitchen half-finished and you had to pay someone else to complete it — you can claim that sum back by filling in the counterclaim section on the same form. State the amount, the factual basis, and the date the issue arose. A counterclaim must stay within the £5,000 small claims ceiling and attracts a court fee (£244 for claims up to £1,000, £269 for claims between £1,001 and £5,000 as of April 2026).

Signature and date. Sign the form. An unsigned 126A will be rejected by the CPC, and if the rejection pushes you past the 21-day window, you risk a default decree.

How to Submit It

Post or hand-deliver the completed form to the Civil Processing Centre, Laganside Courts, PO Box 882, 45 Oxford Street, Belfast BT1 3LL. You can also lodge it at any local County Court office, which will forward it to the CPC.

Use Royal Mail Recorded Delivery and keep the tracking receipt. Filing is effective on the date the CPC physically receives the form — not the date you posted it. If it arrives a day late, you are exposed to a default decree regardless of when you put it in the post.

Common Mistakes

Leaving the defence box too vague is the most frequent error. "I disagree with this claim" on its own gives the District Judge nothing to work with. At the other extreme, attaching pages of argument at this stage is unnecessary — save the detail for your evidence bundle, which is due 14 days before the hearing.

Not checking Form 125 first is the other pitfall. Before filling in 126A, read the applicant's claim carefully: confirm the amount, check whether the claim is liquidated or unliquidated, and note the hearing venue.

What Happens After You Submit

The CPC sends a copy of your 126A to the applicant and transfers the case to the local County Court. Both sides receive a Notice of Hearing with a date, time, and venue. From there, you prepare your evidence bundle and attend the hearing before a District Judge.
