The age of majority refers to a specific age when an individual is said to be an adult and can have certain rights by law due to reaching this age.
For rights granted by reaching the age of majority, the age is 18. However, not all rights associated with the age of majority may be granted at 18.
The right to drink alcoholic beverages is one such right that is not granted by reaching 18 years old. Instead, the age of majority for drinking alcoholic beverages is 21. The right to vote, marry and enter contracts independently are all rights that are granted by reaching 18.
Children who have not reached the age of majority do not have such rights.
