If a paternity test is taken after the child has known the parent as a father for most of their life, it will not matter what the test reveals, and it will not be admissible in court. However, if the results of a paternity test which is taken before a paternal bond is established between a man and child indicate that they are not biologically related, he would no longer have any responsibilities ⁠— financial or otherwise ⁠— toward that child. A person who is determined with 99.9 percent certainty to be the father would be responsible for financially supporting their child.
