The bill amends the Age of Majority Act of 1971 by updating the legal definitions and responsibilities associated with individuals aged 18 and older. It specifies that, beginning January 1, 1972, an individual who is 18 years of age or older is considered an adult with the same legal rights and responsibilities as those who are 21 years of age or older. The bill also clarifies that courts may order support payments for individuals aged 18 and older under various specified acts, including the Child Custody Act and the Family Support Act, among others.

Additionally, the bill supersedes existing laws that impose different duties and rights on individuals aged 18 to 20 compared to those who are 21 and older. It lists numerous public acts that are affected by this change, ensuring that the legal framework is consistent for all adults. However, the bill explicitly states that it does not apply to certain regulations, such as those related to the Michigan Regulation and Taxation of Marihuana Act and the Nicotine and Tobacco Act.
