I've reported this to moderator, for moving to the council tickets forum.
OP, if you're reading this, start a new thread on the above forum. For all we know, the bailiffs are chasing up some other debt. You need to post up whatever documents you received. If this is about a council postal Penalty Charge Notice can you please tell us if your V5 Registration Certificate for the car is up-to-date, (name and address). All ststutory enforcement documents are sent to that address, apart from a parkimg PCN served at the roadside to car or driver.
Edit
Thread has been moved to the council tickets forum, where we await further info from the OP regarding his address on his V5 for the vehicle
