(a) the relationship between the adoptee and the adoptee's parent who is the adoptive stepparent's spouse or deceased spouse;
(b) an existing court order for visitation or communication with a child by an individual related to the adoptee through either parent; or
(c) the right of the adoptee or a descendant of the adoptee to inheritance or intestate succession through or from the adoptee's former parent.
