Since 2016, 27 U.S. states have enacted legislative reforms to end or limited child marriage and this summary offers a concise look at the impacts of these reforms. Variations in minimum age of marriage, legal emancipation requirements, judicial responsibilities, and allowable age differences between spouses, among other legal limitations, are highlighted to give a complete view of what incremental progress has looked like in those states that have not yet set a bright line age of marriage at 18 without exceptions. This document compliments the Map of Legislative Reforms to give more detailed information on current marriage laws in those 27 states that have initiated reforms.
