A contract is like a promise between two people or groups. It means they agree to do something they said they would do, like pay money for something or provide a service.
But sometimes, people don't agree on the terms of the contract, and that's called a conflict. It's like when you and your friend argue about what game to play or what toy to share.
When two people or groups have a conflict about a contract, they might need to get help from a third party, like a judge, to figure out who is right and what should happen next. It's kind of like a grown-up referee who makes sure everyone plays by the rules.
