A CCJ does not work in this way, a CCJ is only recorded in this way if the garage were to default on their payment terms. Simply being ordered to pay someone money and then meeting those terms is not a recordable action.
Indeed. Slightly off topic, and apologies for that, but this is exactly the reason that the private parking companies' scare letters about CCJs are total nonsense. You'll only have a CCJ recorded if:
1. They actually take you to court
2. You lose in court
3. Having lost and been ordered to pay you STILL don't pay
Linkex, well done on seeing this through and congratulations!
