I think the laws on trailers have changed
we have a 400 kg trailer which we bought in the UK 14 years ago.
no paperwork necessary.
now we wish to sell it but prospective buyers are asking about the " paperwork"
when se bought a new Spanish car we had a tow bar fitted and itv'd and it is on the car paperwork which the garage inspected before making a new number plate for it.
what do we do?
the trailer is hardly used, in excellent condition.
it was used when we drove to Spain, but has since only been used briefly a couple of times
