N.J. Stat. § 18A:71C-9
Any contract, promissory note, or other written obligation made by any minor to repay or secure payment of a loan made under this article, payment whereof is guaranteed or insured by the authority, or which forms part of the same transaction as the making of the loan shall, notwithstanding any provision of law to the contrary, be as valid and binding as if the person were at the time of the making and execution 18 years of age, and it may be enforced in any action or proceeding by or against the person in his own name, and shall be valid without the consent of the parent or guardian of the person, and the person shall not disaffirm the instrument because of his age, nor shall the person hereafter interpose the defense that he is, or was, at the time of the making and execution, a minor in any action or proceeding arising out of any such loan.
