1. A man is presumed to be the natural father of a child if:
(a) 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 285 days after the marriage is terminated by death,
annulment, declaration of invalidity or divorce, or after a
decree of separation is entered by a court.
(b) He and the child’s natural mother were cohabiting for
at least 6 months before the period of conception and continued
to cohabit through the period of conception.
(c) Before the child’s birth, he and the child’s natural
mother have attempted to marry each other by a marriage
solemnized in apparent compliance with law, although the
attempted marriage is invalid or could be declared invalid, and:
(1) If the attempted marriage could be declared invalid
only by a court, the child is born during the attempted
marriage, or within 285 days after its termination by death,
annulment, declaration of invalidity or divorce; or
(2) If the attempted marriage is invalid without a court
order, the child is born within 285 days after the termination
of cohabitation.
(d) 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.
(e) Blood tests or tests for genetic identification made
pursuant to NRS 126.121 show a probability of 99 percent or
more that he is the father.
2. A presumption under this section may be rebutted in an
appropriate action only by clear and convincing evidence. If two
or more presumptions arise which conflict with each other, the
presumption which on the facts is founded on the weightier
considerations of policy and logic controls. The presumption is
rebutted by a court decree establishing paternity of the child by
another man.
