When courts look at a contract to see if it's legal, they check a few important things:

• Public Policy: Does the contract support or go against what society believes is right?
• Statutory Compliance: Does the contract follow the laws that apply?
• Oppression or Fraud: Are the terms of the contract fair, or is one person trying to take advantage of another?

If any of these checks don't pass, the contract may not be enforceable. The goal is to make sure everything is fair and that it respects the interests of society!
