(a)  A respondent in a proceeding to adjudicate parentage may admit parentage of a child when making an appearance or during a hearing in a proceeding involving the child or by filing a pleading to such effect. An admission of parentage pursuant to this section is different from an acknowledgment of parentage, as provided in article 3 of this chapter.

(b)  If the court finds an admission to be consistent with the provisions of this chapter and rejects any objection filed by another party, the court may issue an order adjudicating the child to be the child of the individual admitting parentage.
