Welcome. This Recognition of Parentage (ROP) form created by the Minnesota Department of Human Services helps legally establish a biological father’s paternity when the father is not married to the child’s mother. It also allows the father’s name to be on the child’s birth certificate and provides a basis for establishing child support. Signing the form can also be used to change the child’s last name if wanted. This form creates legal rights and responsibilities, so be sure to review all the instructions carefully.
