31. a. If a residential mortgage lender charges or collects interest, costs or other charges on a secondary mortgage loan in excess of those permitted by this act, the licensee may collect only the principal amount of the loan, and may not collect interest, costs or other charges with respect to the loan. In addition, a licensee who knowingly and willfully violates any provision of this act shall also forfeit to the borrower three times any amount of the interest, costs or other charges collected in excess of that authorized by law.

b. The licensee shall have no liability on a secondary mortgage loan for an unintentional error if within 90 days after discovering the error the licensee notifies the borrower of the error and makes adjustments in the account as necessary to assure that the borrower will not be required to pay any interest, costs or other charges which aggregate in excess of the charges permitted under this act for secondary mortgage loans. The discovery of an unintentional error within the meaning of this section shall include an entry of a judgment by a court of competent jurisdiction, holding that a rule or regulation with which the licensee acted in conformity was invalid or in violation of this act, and the licensee shall have no liability for that unintentional error if the licensee takes the actions required upon discovery of the error pursuant to this section, within the time stated therein following entry of the judgment.
