According to the CML rules (as I understand them), two independent valuations are desirable but not, apparently, compulsory. But they should have one independent valuation.(posted 8459 days ago)The CML rules imply that lenders would be wise to provide two independent valuations to protect themselves from charges of negligence. Valuation is a notoriously subjective 'art'.
In your case, do you have 'valuations' or do you have inspection reports, or sales reports, or some such?
I would ask the lender for proof and evidence that these were carried out properly and impartially, at a date subsequent to the repossession, and I would also ask the lender to confirm whether or not it is possession of the original documents from which these copies were made (or are you simply being given copies of copies?).
Ask it to confirm which document is/are the independent valuation(s) you understand that the CML recommend.
