Parentage Amendments

HB 208 amends Utah's parentage laws to clarify and limit timelines for establishing parentage. It limits past child support liability to one year before filing a claim (previously four years), sets new deadlines for filing parentage actions (children must file before age 18, or by age 26 for those born after May 6, 2026), and clarifies how parentage claims can be raised during divorce proceedings. The bill directly affects unmarried biological fathers, birth mothers, and children seeking to establish legal parentage. These changes take effect on May 6, 2026, with no new funding required.
