What should every freelance contract include to prevent getting sued?

[Btaliat]

A freelancer should make sure that he designs the contract in such a way that he will be freed from being sued. That's why it is better you make your Scope of Work clears. With that, you won't be responsible for the scope creep. Apart from that, it is always better for the liability clause to be included. This means that not all money you can be sued for. This will even prevent you from taking low rate tasks.
