ORS 109.151 Adjudicating competing claims of parentage

Except as otherwise provided in ORS 109.148, in a proceeding to adjudicate competing claims of, or challenges under ORS 109.067 (3), 109.070 or 109.072 to, parentage of a child by two or more individuals, the court shall adjudicate parentage in the best interest of the child, taking into consideration, at a minimum:

The age of the child;

The length of time during which each individual assumed the role of parent of the child;

The nature of the relationship between the child and each individual;

The harm to the child if the relationship between the child and each individual is not recognized;

The basis for each individual’s claim to parentage of the child; and

Other equitable factors arising from the disruption of the relationship between the child and each individual or the likelihood of other harm to the child.

If an individual challenges parentage based on the results of genetic testing, in addition to the factors listed in subsection (1) of this section, the court shall consider:

The facts surrounding the discovery the individual might not be a genetic parent of the child; and

The length of time between the time that the individual was placed on notice that the individual might not be a genetic parent and the commencement of the proceeding.
