A written agreement by a stepparent to support his or her minor stepchild must be
acknowledged by the stepparent before a notary public or other person authorized to administer
oaths. See Moyer v. Moyer, 122 N.C. App. 723, 471 S.E.2d 676 (1996). The liability of a
stepparent or other person standing in loco parentis for the support of a child is secondary to that
of the child’s parents. See Duffey v. Duffey, 113 N.C. App. 382, 438 S.E.2d 445 (1994).
