“We hold that a law firm that prepares promissory notes or undertakes debt collection activity on behalf of a HOA client is not subject to the MCLL because it is not a ‘lender’ that is ‘engaged in the business of making loans’ under the provisions of the MCLL,” Judge Brynja M. Booth wrote on behalf of the 7-1 majority. “Rather, a law firm is in the business of providing legal or debt collection services to its client.”
