Notwithstanding any other provision of this article, a distribution from the estate of a decedent or payment made by a trustee, insurance company, pension fund, or any other person or entity that was made in good faith reliance on a judgment establishing paternity that is final for purposes of direct appeal, may not be set aside or subject to direct or collateral attack because of the entry of an order setting aside or vacating a judgment under this article. An estate, trust, personal representative, trustee, or any other person or entity that made that distribution or payment may not incur any liability to any person because of the distribution or payment or because of the entry of an order under this article.
