Proposes a constitutional amendment that changes a valid marriage from a marriage between a man and a woman to two persons regardless of their genders

HJR 183 proposes a constitutional amendment to change Missouri's definition of marriage from "a marriage between a man and a woman" to "a marriage between two persons regardless of their genders." If approved by voters, this amendment would directly affect all Missouri residents seeking marriage licenses and change the state's constitutional marriage definition. The bill requires voter approval in a general or special election after the legislature passes it, with the next vote scheduled for November 2026. This is a substantive policy change to marriage rights, not a procedural measure. The amendment would replace the current constitutional language defining marriage.
