An oral contract is when two people agree on something using their words instead of writing it down on a piece of paper. It's kind of like making promises to each other. For example, if your friend says "I'll give you a candy bar tomorrow if you help me clean my room today," and you say "OK," that's an oral contract. But, it's important to know that oral contracts aren't always as strong as written contracts because it can be hard to remember exactly what was said and agreed upon. That's why it's usually better to write things down so everyone can remember and understand what they are agreeing to.
