Most guides on setting aside a CCJ mention "a good reason" and "a real prospect of defence" as if they're two boxes on the same checklist. They're not. They come from two different rules with two completely different tests — and knowing which one actually applies to your situation changes how strong your case is, and what you need to prove.
The two routes, in plain terms
| CPR 13.2 — Mandatory | CPR 13.3 — Discretionary | |
|---|---|---|
| What the court must do | Set the judgment aside — no choice involved, if the ground applies | May set it aside, weighing the evidence |
| What you need to show | The judgment was wrongly entered | A real prospect of successfully defending, and that you acted promptly |
| Do you need a defence? | No — the process itself was flawed | Yes — genuinely, not just denial |
CPR 13.2: when the judgment was wrongly entered
This applies where something about how the judgment was obtained was procedurally wrong — regardless of whether you have a good defence to the underlying debt. If CPR 13.2 applies, the court has no discretion: it must set the judgment aside.
Example: the claim form was never properly served
Sarah moved house eight months ago and updated her bank and utility providers, but an old creditor still had her previous address on file. The claim form was sent there and never reached her. Because the claim was never validly served on her at her correct address, this falls under CPR 13.2 — the court must set the judgment aside, regardless of whether Sarah ultimately owes the money.
Example: you'd already paid before judgment was entered
Tom paid off a small business invoice in full three days before judgment was entered against him — the payment simply hadn't been processed on the claimant's end yet. Since the debt was already settled at the point judgment was entered, this is a CPR 13.2 case: the judgment was wrongly entered on its facts.
CPR 13.3: when you're asking the court to use its discretion
This is the route most people end up using, because most default CCJs happen when someone genuinely didn't respond in time — not because of a service failure, but because they missed it, ignored it, or didn't understand what it was. Here, the court has to weigh two things together:
- A real prospect of successfully defending the claim — more than simply saying "I don't think I owe this." You need to show specific reasons: the amount is wrong, the debt isn't yours, it's statute-barred, or similar.
- That you applied promptly once you found out about the judgment. There's no fixed deadline, but delay without a good explanation weakens the application significantly.
Example: a genuine dispute over the amount
Priya received a claim for £4,200 relating to a contract dispute, didn't respond because she assumed her old accountant was handling it, and a default judgment followed. She has evidence the actual amount owed was closer to £1,800 due to work that was never completed. This is a CPR 13.3 case: no procedural failure, but a genuine, evidenced defence — and she needs to show she's applying promptly now that she's aware.
Why the distinction actually matters
If your case is genuinely a CPR 13.2 situation, framing your witness statement around "I have a good defence" is the wrong emphasis — the court doesn't need you to prove a defence at all, it needs to see that the judgment was procedurally flawed. Conversely, treating a CPR 13.3 case as if it's automatic ("I never got round to it, please set it aside") without addressing the real-prospect-of-defence test is one of the most common reasons applications get refused.
Getting this right from the start — identifying which rule actually fits your facts — shapes the entire witness statement, not just a line or two of it.
