Depends on what the lender is really looking for. A "Recertification of Value" is performed to confirm whether or not the conditions of an appraisal have been meet. A Recertification of Value does NOT change the effective date of the value opinion. Lines 3484-3483, page 100 2002 USPAP.
So if the client only wants to know if the home was completed per plans and specs and did the appraiser really and truly say the home was worth $1 on 01-01-2001, then they are looking for a "recert" as defined in the above quoted lines of USPAP. And the different appraiser than original would need to have a copy of the plans and specs to compare to what was actually constructed.
If they want to know if the value as of 09-25-2002 is at least the $1, then it is a completely new assignment. An "Update of an Appraisal" is defined as an extension of the original Complete or Limited Appraisal and a report relied on by a client for a prior business decision. The Update of an Appraisal changes the effective date of the value opinion. Lines 3477-3480, page 100 2002 USPAP.
So if you did NOT do the original report, your report could NOT be an extension of the original report, you wouldn't be able to do an "Update". Since you are not the same appraiser as the original, you could only offer a new 2055 or a new 1004 with a new effective date. If they don't want a new 2055 or new 1004 and do want to know if the value is still $1 on 09-25-2002, then the lender needs to contact the original appraiser for an Update of an Appraisal. Which that appraiser could do either in a letter form (if the market and the subject has not changed) or a new 1004 or new 2055 if something has changed.
Talk to someone at the lender's office that knows what they are really doing, not just the receptionist that was handed a note to call an appraiser for a "recert"!
