Indiana Code Title 28. Financial Institutions § 28-1-20-6

Sec. 6. When, in case of any loan made by any bank or trust company, the borrower, or any other person furnishing security on behalf of the borrower, shall, as an inducement to the bank or trust company to make the loan, represent to it, in writing, that he or she is eighteen (18) years of age or older, whereas in fact such person or persons are under the age of eighteen (18) years, or shall otherwise make any false statement or representation to the bank or trust company, and the bank or trust company is thereby deceived, and the loan is made in reliance upon such representation, neither the person so representing, nor any one in his or her behalf, nor any person otherwise legally liable to pay such loan, shall afterwards be allowed, as against such bank or trust company, to take advantage of the fact that the person making the representation was under eighteen (18) years of age, but each such person shall be estopped by such representation.
