I'm just thinking out loud here and would love to hear others comments.
I appreciate this discussion David and Rocky, and find it intriguing as I have always taken the conservative approach and just provided the AA notice under Reg B (typically the combined denial/counteroffer) rather than taking a deep dive into what is technically required.
First, I agree with David that I think an AA is clearly required under the FCRA. To support this, the 7/15/11 final Reg B rule (for AA Notices) states the following:
In contrast, section 615(a) of the FCRA requires a creditor to provide the disclosures mandated by that section to ``any consumer'' against whom adverse action is taken, if the adverse action is based in whole or in part on information from a consumer report.Based on this, I think it is pretty clear that an FCRA AA notice must be provided.
For Regulation B, I agree that it isn't as clear but I think we can find some answers in the Reg and commentary. First, I think it is important to start with the notification requirements. As we all know, these are found in 1002.9(a)(1) and have the following requirements:
A creditor shall notify an applicant of action taken within:(i) 30 days after receiving a completed application concerning the creditor's approval of, counteroffer to, or adverse action on the application;" ..... (iv) 90 days after notifying the applicant of a counteroffer if the applicant does not expressly accept or use the credit offered.To me, the key piece of this is where the rule says "an applicant" or "the applicant." So, let's review the definition of an applicant:
(e) Applicant means any person who requests or who has received an extension of credit from a creditor, and includes any person who is or may become contractually liable regarding an extension of credit.When reviewing this definition, I note that all references are singular: they reference "any person." To me, this means that all co-applicants are also an "applicant" by definition, meaning that each is a separate "applicant" subject to the rules.
This singular approach to "applicant" is referenced throughout the reg. For example, the definition of "adverse action" says:
A refusal to grant credit in substantially the amount or on substantially the terms requested in an application unless the creditor makes a counteroffer (to grant credit in a different amount or on other terms) and the applicant uses or expressly accepts the credit offered;Furthermore, the commentary to 1002.9(a)(1) also references a singular applicant in reference to a counteroffer:
6. Counteroffer combined with adverse action notice. A creditor that gives the applicant a combined counteroffer and adverse action notice that complies with §1002.9(a)(2) need not send a second adverse action notice if the applicant does not accept the counteroffer.So, based on this consistent singular use of "applicant," it appears to me the "dropped" co-applicant (who, by definition is an "applicant') did not get a counteroffer and, therefore, must receive notification within 30/90 days. In other words, I vote that an adverse action notice under Regulation B (as well as FCRA) would be required for the "dropped" applicant on an accepted counteroffer.
All of that said, I could be wrong and I've not been able to locate the original Reg B issuance that may or may not have additional pre-amble that might provide further insight to this. SO, if one of the older/wiser gurus (cough, Randy, cough, cough, John, cough, cough

) has a link to the original issuance, I'd love to see it. Again, I appreciate this discussion, David and Rocky.
