(a) Subject to the provisions of subsection (b) of this section and §§ 8-607 and 8-609 of this title, a proceeding under this subchapter may be commenced at any time until the child reaches the age of majority, except as provided in §§ 501(d) and 503 of this title.

(b) A proceeding to adjudicate the parentage of a child having no presumed, acknowledged, adjudicated or adoptive father may be commenced at any time, even after:

(1) The child becomes an adult but only if the child initiates the proceeding; or

(2) An earlier proceeding to adjudicate paternity has been dismissed based upon the application of a statute of limitation then in effect.

(c) In a proceeding under subsection (b) of this section, the court may deny a motion for genetic testing based on principles of estoppel as established in § 8-608 of this title.

(d) This section shall not extend the time within which a right of inheritance or a right to succession may be asserted beyond the time provided by law relating to distribution and closing of decedents’ estates, nor to the determination of heirship, or otherwise.

(e) Notwithstanding the 2-year period of limitation recited in this chapter or other affirmative defense, an action for parentage may proceed despite a prior adjudication, acknowledgement or presumption of parentage when shown by clear and convincing evidence to be in the best interest of the particular child, and where the prior adjudication, acknowledgement or presumption of parentage was based on fraud or duress or material mistake of fact.
