In theory they can as the vehicle is not owned by Motability or on any other type of finance. However its taxation class renders it part of the "vulnerable" category under the National Standards to which supposedly all enforcement companies comply with. A DVLA check will just come back with the name of the RK which in itself is meaningless as that is not necessarily the legal owner.

A glance at the RFL in the windscreen should tell the bailiff all he needs to know and he should leave well alone as he knows he risks the wrath of his employer and their employer - in this case the LA. I'm afraid it will come down to a case of bluff and double bluff but stand your ground and he will slink off with his tail between his legs.

Of course you also have to remember that bailiffs read these forums!!!!!
