A mortgage Co asked me to sign an " Access to funds " form

[Edwin E.]

A mortgage Co I'm dealing with asked me to sign the above mentioned form. That's new to me. It says " This letter is to certify that ............ has 100% access to our joint account #.... " In the past I have provided the usual bank statements but I don't remember being asked to give access to my funds. I would like your input on this. Is this something new and legit or is this " Peoples Mortgage Company trying to take me to the cleaners ? ( Closing day is next Thursday so I'm in a hurry to send all docs needed ) Thanks in advance for your help.
