Mortgage Joker

I have a self employed client who asked me to provide to the prospective lender via a mortgage broker a certificate of profit shown in her unaudited accounts for the last three years - pretty normal stuff! I am now informed that the Spanish-owned high street name lender objects to the fact that my firm believes the information is correct but takes no responsibility in law. In other words it objects to the disclaimer and expects me to take responsibility for someone else's mortgage.

I wondered if anyone else has come across this? Is it ignorance by some junior in white socks or paranoia in the current climate of panic?. Either way, obviously I am not budging, but the client is blaming me in part for the hold up in her funds. As far as I am concerned the broker is being paid to sort out this nonsense, not me.
