Fatherhood is the state of being a father, which involves providing care and support for one's children. PATERNITY is the legal recognition of a father's relationship to his child, which is established through a legal process such as a birth certificate or court order. Fatherhood and PATERNITY are closely related concepts, but they are not the same. Fatherhood is a social role that involves providing emotional and financial support to one's children, while PATERNITY is a legal recognition of the biological relationship between a father and his child.
