In cases of paternity in New York, a child that was born during marriage is legally presumed to be abiological product of that marriage, and this presumption historically was one of the most persuasive in law. However, it’s important to note that this presumption is still subject to the sway of reason, though statements have varied regarding the sufficient evidence required to rebut such a presumption. For instance, in the context of a case wherein a child is born during a marriage, the presumption should not fail unless there is evidence to demand reconsideration. In fact, if a husband and wife live together, legitimacy is often presumed, and even if the couple are living apart, the court can provide a fair basis for the believe that a child was born as a product of times the couple were brought together.
During recent years, case law that enunciates the presumption of legitimacy in paternity cases where a child is born during a marriage has been pulled into question. This isn’t necessarily because the reasoning and logic behind that case law has changed over time, but because the passage of time have delivered new updates in technology and science that make determining legitimacy accurately, more possible. In past cases, one of the primary – if not the only determining factor in the application of a presumption of legitimacy in court was access between the husband and wife. However, as we have progressed further into modern times, DNA tests and blood tests have also acquired a new ability to sway reason. Because of this, while the presumption of legitimacy still serves a laudable purpose, it remains to be just another legal presumption that can be used when conclusive evidence to the contrary is not available.
