MINOR PARENTS: If the mother or potential father is less than 18 years of age a Voluntary Paternity Acknowledgment can not be filed. A paternity action will be started and a Guardian ad litem (attorney) will be appointed to represent the minor parent. The Guardian ad litem will determine what is in the best interest of the minor. In some cases the Guardian ad litem will request that the Court order genetic testing, even if the parties are not requesting it. You can find more information about establishing paternity at Legal Fatherhood.
