Affidavits of Paternity

Dad and childA paternity affidavit is a legal document that permits a man and a woman to declare, under penalty of perjury, that the man is the biological father of a child. A properly executed paternity affidavit establishes legal paternity (fatherhood) and parental rights and responsibilities, without the necessity of obtaining a court order.

A paternity affidavit may be completed at the hospital within 72 hours of the child’s birth or at the local health department any time before the child is emancipated. If paternity is established by paternity affidavit, the Department of Health will add the father’s name to the child’s birth certificate.

The office is open Monday-Friday, 8 a.m. to 4:30 p.m. except on holidays observed by Allen County Government. You can park in the parking lot off Berry Street or there is metered parking nearby.
