MS HB277

Lowers Mississippi's age of majority from 21 to 18 years old, making 18-year-olds legal adults for most purposes including jury service, marriage license eligibility without parental consent, and full contractual capacity

Terminates child support obligations when a child reaches 18 years of age (provided they are no longer attending high school), rather than the previous age of 21

Updates criminal penalties so that adults 18 and older who distribute controlled substances to minors under 18 face enhanced punishment, aligning with the new age threshold

Repeals provisions allowing special removal of minority disabilities for veterans and certain estate executors/administrators, as these become unnecessary with the lowered age of majority

Amends over 20 Mississippi Code sections to conform definitions of "infant," "minor," "adult," and related terms to the new 18-year threshold, effective July 1, 2026
