A Massachusetts Complaint to Establish Paternity is a legal document used to ask the court to determine the paternity of a child. It is typically filed by the Department of Revenue (FOR) on behalf of the child's mother or the biological father. The complaint must include the names and addresses of all parties involved, the details of the alleged father's paternity, and evidence of the father's paternity. There are two types of Massachusetts Complaint to Establish Paternity: an Administrative Complaint and a Judicial Complaint. The Administrative Complaint is filed by the FOR with the Massachusetts Department of Transitional Assistance (DTA), and the Judicial Complaint is filed by the mother or the biological father with the court. Both types of complaint require the father to submit a DNA test to prove paternity.
