RESPA Reg X – Affiliated Business Arrangements – applies to consumer credit. The required use of the AfBA form however, can be driven by state law. For example Virginia’s rule for an attorney:

While the RESPA AfBA disclosure form is probably sufficient for ethics compliance, an attorney must disclose an AfBA relationship in circumstances in which a RESPA disclosure is not required...e.g., cash or commercial transactions, or in which the attorney's interest is less than one percent. (AfBA required on commercial loans)

I am researching the Ohio Code and as this point do not see any reference to profiding the AfBA to commercial loan customers. Anyone?

As far as I know if the loan is not a RESPA loan than the AfBA is not required.

Again, thank you for your time in responding.
