1. A. Except as otherwise provided by Section 215 of Title 84 of the Oklahoma Statutes, a man is presumed to be the natural father of a child for all intents and purposes if:

   1. 1. He and the child's natural mother are or have been married to each other and the child is born during the marriage, or within ten (10) months after the termination of the marriage by death, annulment, declaration of invalidity, divorce or dissolution, or after a decree of separation is entered by a court. A child born before wedlock becomes legitimate by the subsequent marriage of his parents even if the marriage is, was or could be declared invalid. Any child born within the ten-month period specified in this subsection which is born during a subsequent marriage to another person shall be presumed to be the legitimate child of that subsequent marriage;
   2. 2. Before the child's birth, he and the child's natural mother have cohabitated and the child is born within ten (10) months after the termination of cohabitation. As used in this paragraph, the term cohabitation means the dwelling together continuously and habitually of a man and a woman who are in a private conjugal relationship not solemnized as a marriage according to law;
   3. 3. While the child is under the age of majority, he receives the child into his home and openly holds out the child as his natural child for a period of at least two (2) years;
   4. 4. The United States Immigration and Naturalization Service made or accepted a determination that he was the father of the child at the time of the child's entry into the United States and he had the opportunity at the time of the child's entry into the United States to admit or deny the paternal relationship; or
   5. 5. Statistical probability of paternity is established at ninety-five percent (95%) or more by scientifically reliable genetic tests, including but not limited to blood tests.
2. B. The presumption of paternity created pursuant to this section may be disputed pursuant to Section 3 of this title.
