MS SB2643

Lowers the age of majority in Mississippi from 21 to 18 years old, making persons 18 years of age adults for purposes of legal capacity and contractual rights.

Updates definitions of "infant" and "minor" throughout Mississippi Code from 21 years to 18 years of age, with exceptions where specific sections provide otherwise.

Modifies statutes related to jury service, marriage licenses, adoption, guardianship, child support, inheritance, and property conveyance to reflect the new age of majority at 18.

Establishes that child support obligations terminate when a child attains age 18, unless the child is still attending high school, is mentally or physically incapable of self-support, or other enumerated circumstances apply.

Repeals four outdated sections that allowed removal of disabilities of minority for veterans, certain estate administrators, married persons, and 18-year-olds, making them unnecessary under the new age of majority.

Takes effect July 1, 2025.
