South Dakota Legal Ages Laws

South Dakota’s age of majority is eighteen years old. Ordinarily, minors younger than eighteen need a parent or guardian to exercise legal rights and consent to a various decisions and activities (remember those permission slips?).

There are circumstances where minors can make decisions without a parent or guardian, however. South Dakota permits minors to become emancipated once they’re married, are serving on active duty in the military, or following a court-approved agreement with their parents.

South Dakota’s Legal Age Laws

Most legal age laws exist to protect minors. While minors can sue to enforce their legal rights, they need to proceed through a parent or guardian. A guardian ad litem can be appointed for minors without an existing guardian. There’s also a prohibition on minors making contracts relating to real property (such as real estate) or personal property outside of their immediate possession.

South Dakota joins many states in allowing minors to get out of, or “disaffirm,” most contracts entered into before the age of majority. Exceptions exist for contracts relating to necessities and as otherwise permitted by law. Also, minors can consent to being tested and treated for venereal diseases on their own.

The following table provides a summary of South Dakota’s legal age laws:
