The New York Family Court Act allows paternity proceedings to be initiated until a person is 21 years of age. According to Matter of Shondel, a person in doubt about whether he is the father of a child must request a DNA test prior to assuming the role of a father. Otherwise, he may be precluded from doing so in the future if it is not within the “best interest of the child”. In addition, a woman seeking to have a partner take a DNA test after a father-child relationship is already established may be precluded from doing so, if it will negatively impact the child.
