Missouri Legal Ages Laws
State Legal Age Laws: Overview
Those who are 18 and older are considered adults in the eyes of the law, but many states also set age limits for minors with respect to certain legal obligations and privileges. For instance, minors in most states may consent to certain medical treatments or petition the court for emancipation from one's parents. In general, state laws identify certain legal processes that minors may encounter and have made exceptions to accommodate them.
Summary of Missouri Legal Age Laws
Missouri statute does not specify age limits below the age of majority (18), but it does offer some limited exceptions for minors. For instance, a minor may consent to medical treatment if married or if the treatment is for pregnancy, sexually transmitted infections, or substance abuse. Additionally, a married minor (if the spouse is 18 or older) may be included in the joint ownership of real estate.
The state does not have a formal procedure for the emancipation of minors, in which a minor is declared an "adult" in the eyes of the law (and thus eligible for all of the privileges and responsibilities of adulthood). But Missouri does allow for the emancipation of minors by court order in some limited circumstances, which include:
- Express parental consent (waiving parental rights)
- Implied parental consent (minor is already living apart from parents and supporting him or herself)
- Significant change in status (this may include military enlistment or marriage)
