Legal DNA Affidavit Letter Sample

For unmarried fathers, a voluntary Acknowledgment of Paternity can help establish the legal rights and responsibilities as the child's parent.

Child visitation, custody and child support can only be ordered by the court after paternity is established. This can be accomplished  when the alleged father voluntarily admits to be the father or is ordered by the court to provide saliva sample for the genetic (DNA) testing to be compared to the mother and child.

In order to establish paternity right after the birth of a child, a declaration of paternity can be provided at the hospital and after completed and signed by both parents without having to go to court.

Also, the Department of Child Support Services can provide a Declaration of Paternity to be completed if it was not done at the hospital right after the birth.
