(a) In this section, "child" includes any person for whom an order or judgment for child support has been entered in this or another State.

(c) The exception in subsection (b) is unenforceable against a special needs trust, supplemental needs trust, or similar trust established for a disabled person if the applicability of such a provision could invalidate such a trust’s exemption from consideration as a countable resource for Medicaid or Supplemental Security Income (SSI) purposes or if the applicability of such a provision has the effect or potential effect of rendering such disabled person ineligible for any program of public benefit, including, but not limited to, Medicaid and SSI.
