A stepparent has a duty to support a stepchild if they reside in the same household and if the financial resources of the natural or adoptive parents are insufficient to provide the child with a reasonable subsistence consistent with decency and health. The duty of a stepparent to support a stepchild under this section shall be coextensive with and enforceable according to the same terms as the duty of a natural or adoptive parent to support a natural or adoptive child including any such duty of support as exists under the common law of this State, for so long as the marital bond creating the step relationship shall continue.
