Age of majority; revise.

SB 2031 lowers Mississippi's age of majority from 21 to 18 years old. The bill amends over 20 sections of Mississippi law to replace "21" with "18" wherever the age of majority is referenced, including definitions of "infant," "minor," and "adult" in statutes related to contracts, jury duty, marriage licenses, adoption, guardianship, and legal capacity. It also repeals outdated provisions that previously allowed certain groups (like veterans or executors) to have disabilities of minority until age 21. This change directly affects all Mississippi residents reaching age 18, granting them full legal adulthood for these specific legal matters.
