A child support case does not always turn on biological parentage. In some situations, New York courts will prevent a person from denying paternity even when genetic testing proves that the person is not the child’s biological father. This legal principle is known as paternity by estoppel. The doctrine focuses on the best interests of the child rather than the biological relationship between the parties.
