A more thorough explanation:

Definition: Bonae fidei (boh-nee fI-dee-I) is a Latin term that means "of good faith" or "in good faith."

• When signing a contract, both parties are expected to act in bonae fidei.
• A seller must disclose any known defects in a product to the buyer in bonae fidei.

These examples illustrate how the term bonae fidei is used to describe a situation where both parties are expected to act honestly and in good faith. In the first example, both parties are expected to fulfill their obligations as outlined in the contract without any deceit or dishonesty. In the second example, the seller is expected to provide accurate information about the product to the buyer, even if it may negatively impact the sale.
