Could you explain what this means then

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).

The language you cite deals with the enforceability of a contract. The child support guidelines state that you may receive a credit for your natural child or a step child that you have adopted. Case law research and interpretation is beyond the scope of this forum.
