The Massachusetts Affidavit of Paternity is a legal document used to establish that an individual is not the father of a child. This document is used when a man is listed as a father on a child’s birth certificate, but he is not the biological father of the child. The Massachusetts Affidavit of Paternity is available in two forms: a Voluntary Affidavit of Paternity, and a Court-Ordered Affidavit of Paternity. The Voluntary Affidavit of Paternity is completed by the alleged father and mother, with both parties signing the document in front of a notary. The mother must also provide proof of her identity, such as a valid driver’s license or state-issued ID. The Court-Ordered Affidavit of Paternity is filed in court by either the alleged father or the mother of the child, and requires a court hearing. Both parties must attend the hearing, and the court will make the final determination as to the paternity of the child. The Massachusetts Affidavit of Paternity is an important document that is used to establish the legal parentage of a child and can have implications for other matters such as child support and inheritance.
