Marriage - As enacted, prohibits marriage between first cousins. - Amends TCA Title 36, Chapter 3.

This bill amends Tennessee's marriage laws to prohibit unions between first cousins by changing the legal definition of prohibited relationships. The key provision replaces the phrase "child of a grandparent" with "lineal descendant of a grandparent" in the state code, which effectively bans marriage between first cousins while allowing marriage between second cousins and other more distant relatives. The change applies to all individuals in Tennessee who wish to marry and directly impacts the state's marriage registry and legal definitions of kinship.
