Trust law is a way for someone to give their property to another person or organization to take care of. You might want to do this if you want someone else to manage your money or if you want to give your money to some people after you die. The person or organization that you give the money to is called a trustee. It's like if you give someone a special job of looking after something you care about. The trustee has to follow special rules, like needing to use your money for things that you said it could be used for and not keeping the money for themselves. Trust law is important so that people have good protection for their money and that trustees follow the rules.
