The ratification of Chapter 50, section 13.10 of the North Carolina General Statutes, effective October 1, 1987, now focuses attention on the retroactive modifiability of court-ordered child support obligations in this state. Retroactive liability for child support, however, is not limited to retroactive changes in court-ordered support. The concept also includes retroactive changes in contractual child support obligations, as well as several miscellaneous remedies that allow a court to reimburse a parent, the state, or a third-party provider of necessaries for past expenditures on the child's behalf.
