Presumption of paternity in paternity law and common law is the legal determination that a man is "presumed to be" a child's biological father without additional supportive evidence, usually as a result of marriage.
Generally associated with marriage, [1] a presumption of paternity can also be made by court order, contact over time with a child, or simple cohabitation with the mother.
[2] If there is no presumption of paternity, a process such as recognition may be used to establish paternity.
