Age of majority; revise.

HB 277 proposes lowering Mississippi's age of majority from 21 to 18 years old, directly affecting all residents turning 18. It would revise over 15 sections of state law to replace references to "21" with "18," including updating marriage license eligibility, contractual capacity (allowing 18-year-olds to enter binding contracts independently), jury service requirements, and legal definitions of "infant" or "minor." Key provisions also adjust age limits for inheritance, adoption, guardianship, and tort claims, while repealing outdated sections related to veterans' or executors' legal disabilities. This is a comprehensive consistency update across civil, family, and procedural laws, not a new policy.
