   A. Except as otherwise provided by paragraph 3 of subsection B of
   Section 7503-2.7 of this title:
   
   1. When an interlocutory or final decree of adoption has been
   rendered, a decree terminating parental rights cannot be challenged on
   any ground, either by a direct or a collateral attack, more than three
   (3) months after its rendition. The minority of the natural parent
   shall not operate to prevent this time limit from running; and
   
   2. No adoption may be challenged on any ground either by a direct or
   collateral attack more than three (3) months after the entry of the
   final adoption decree regardless of whether the decree is void or
   voidable, and the minority or incompetence of the natural parent shall
   not operate to prevent this time limit from running.
   
   B. In any challenge on any ground either by a direct or collateral
   attack, the court shall not enter a decision which is contrary to the
   best interests of the adopted minor.
