In a CINA proceeding involving children born during their mother’s decade-long estrangement from her husband, who is presumed by law to be their father, the court’s order denying husband’s motion for genetic testing to disestablish paternity was not appealable as a final judgment; it did not change custody or adversely affect appellant’s right to the children’s care and custody; nor did it fall within the collateral order doctrine, as it did not conclusively establish parentage.
