(1) Any interested party may bring an action for the purpose of determining the existence or nonexistence of the father and child relationship presumed pursuant to 40-6-105.
(2) An action to determine the existence of the father and child relationship with respect to a child who has no presumed father under 40-6-105 may be brought by the child, the mother or personal representative of the child, the department of public health and human services or its appropriate local affiliate, the personal representative or a parent of the mother if the mother has died, a person alleged or alleging to be the father, or the personal representative or a parent of the alleged father if the alleged father has died or is a minor.
(3) Regardless of its terms, an agreement, other than an agreement approved by the court in accordance with 40-6-114 (2), between an alleged or presumed father and the mother or child does not bar an action under this section.
(4) If an action under this section is brought before the birth of the child, all proceedings must be stayed until after the birth, except service of process and the taking of depositions to perpetuate testimony.
