A more thorough explanation:

Definition: Fair on its face refers to a document that appears to be legal and regular, and cannot be proven to be defective without additional evidence.

Example: A contract that is signed by both parties and contains all the necessary terms and conditions is fair on its face. It appears to be a valid and binding agreement, and any defects or issues with the contract would need to be proven with additional evidence.

Explanation: The term "fair on its face" means that a document appears to be legally sound and valid without any additional evidence. This means that if a contract, for example, is signed by both parties and contains all the necessary terms and conditions, it is considered fair on its face. However, if there are any issues or defects with the contract, they would need to be proven with additional evidence. This term is often used in legal contexts to describe documents that appear to be valid and binding.
