Hi Bev,(posted 8208 days ago)There have been AT LEAST 3 further revised editions of their standard mortgage terms & conditions since 1983 through to 1996 ('cos I got 'em tucked away in my not so little Abbey folder).
I should ask them to explain why they think the T&C they have supplied are of relevence to your 1996 mortgage, as you are able to obtain evidence to the contrary (I'll send you copies if required to back up this claim, although make them do some work first by insisting they supply you with the relevent edition).
As for their other fairly standard (we can't be bothered to do any work)excuses, Go to the page on the site entitled "learn how lenders resist proving shortfall debt-and how to respond" in the do's and don'ts section. There you'll find some excellent responses to put in your letters.
Good luck
Stephen
