👉 In law, a paternity is the biological relationship between two or more individuals. It refers to the legal status of an individual as the father of another person's child. Paternity can be established by DNA testing, where the mother and the father share identical genetic material, or through adoption if one parent has chosen to adopt the other. In some jurisdictions, paternity may also be determined based on circumstantial evidence such as medical records, court orders, and witness testimony.
