Is the presumption of paternity the law in any of the states? If so, which ones. Or is an unwritten understanding? Or something that no longer applies?
As I understand it (or misunderstand it), when a man and a woman are married and have a child, the law presumes the baby to the child of said man.
Further, the paternity of that child cannot be challenged. Is this true? And does that go for both parents?
IANAL. In Wisconsin under Wis stat. ch 891 the issue of a married woman is legally presumed to be the issue of the husband. Paternity can be challenged by certain parties (including the natural mother, the child or the man presumed to be the father) under Wis stat. ch 767.45 for the purpose of rebutting the presumption of paternity.
IANAL (I’ve always wanted to say that!). My understanding is that this is perhaps the single subject where the law varies the most between states. In some states the presumption is exactly as you have described it. In other states, the rules are completely different.
In Stranger in a Strange Land, the Valentine Michael Smith character was described as “the legal offspring of three parents”, not because he came from Mars, but because one of his fathers came from a state where the husband was presumed to be the father, and one came from a state where the biological father was recognized as the father.
I would guess that all the states have statutes similar to Wisconsin’s. The biological father, however, is always recognized as the father in any state. The statute confers a ** rebuttable** presumption. This presumption can be refuted, and DNA evidence, of course, would be the primary method of refuting the presumption.
Definitely an incorrect “guess.” Brother Cadafel’s view is much more accurate. Some states do allow a conclusive presumption of paternity. For example, California:
The Supreme Court of the United States upheld the constitutionality of conclusive-presumption statutes in Michael H. v. Gerald D., 491 U.S. 110 (1989). Justice Scalia’s opinion announcing the Court’s judgment gives an interesting history of presumed-paternity laws.
California is an anomaly in oh so many ways. But it is not alone here. California is one of 19 states that have adopted the Uniform Parentage Act in some form. The Parentage Act provides a rebuttable presumption in some cases, but retains the common law’s conclusive presumption if the mother and a putative father acknowledge the putative father’s paternity, and do not rescind it within 60 days, in which case the putative father’s paternity is conclusively presumed. Thus, if a cuckolded husband mistakenly believes that his wife’s child is his, and acknowledges his paternity, then he is conclusively presumed the child’s father and that presumption extinguishes any claim of paternity that the true biological father might have asserted. The 1973 Uniform Parentage Act was updated in 2002 in response to congressional pressure for greater certainty regarding paternity in child-support proceedings:
Just by way of clarification, my quote from Stranger should not be taken as a citation of legal precedent, but as an example of the kind of legal oddity that could result from widely varying state laws.
This is one area where the differences amoung state laws are most pronounced. Perhaps the only other area as widely varying would be regulation of alcoholic beverages.
