N.J. Stat. Ann. § 9:17A-1

1. The consent to the performance of medical or surgical care and procedure by a hospital or by a physician licensed to practice medicine and surgery executed by a married person who is a minor, or by a pregnant woman who is a minor, on his or her behalf or on behalf of any of his or her children, shall be valid and binding, and, for such purposes, a married person who is a minor or a pregnant woman who is a minor shall be deemed to have the same legal capacity to act and shall have the same powers and obligations as has a person of legal age. Notwithstanding any other provision of the law, an unmarried, pregnant minor may give consent to the furnishing of hospital, medical and surgical care related to her pregnancy or her child, although prior notification of a parent may be required pursuant to P.L.1999, c.145 (C.9:17A-1.1 et al.) and such consent shall not be subject to disaffirmance because of minority. The consent of the parent or parents of an unmarried, pregnant minor shall not be necessary in order to authorize hospital, medical and surgical care related to her pregnancy or her child.
