A. A person who is adopted or born out of wedlock and that person's descendants, if appropriate to the class, are included in class gifts and other terms of relationship in accordance with the intestate succession under article 1 of this chapter.
Terms of relationship that do not differentiate relationships by blood from those by affinity, such as "uncles", "aunts", "nieces" or "nephews", are construed to exclude relatives by affinity.
Terms of relationship that do not differentiate relationships by the half blood from those by the whole blood, such as "brothers", "sisters", "nieces" or "nephews", are construed to include both types of relationships.
B. In addition to the requirements of subsection A, in construing a dispositive provision of a transferor who is not the adopting parent, an adopted person is not considered the child of the adopting parent unless the adopted person lived while a minor, either before or after the adoption, as a regular member of the household of the adopting parent at any time.
