About paternity in Indiana
Paternity refers to the legally established relationship between a child and the child's father. If paternity is not legally established, the father has no rights to the child. Establishing paternity also means, however, that the father has legal obligations to support the child. Paternity may be established at the hospital at the time the child is born by signing a paternity affidavit. If there is a dispute over paternity, then a Court may order a DNA test to establish it.
