Buying and selling property of any kind requires a contract. Therefore, you generally have to be the age of majority, as minors can usually only enter into restricted kinds of contract. If you own land, your parents or your trustee(s) will usually have to take care of any transaction involving the land. Since it is still your property, if someone wants to sell your land, they will have to go to court and explain why the sale is necessary. You may also have to provide a formal agreement to the transaction. Last Reviewed: November 2019
