The term "good faith" refers to a sincere intention or belief that one's actions are in another person's best interest. It is often used as an agreement between parties, where each side trusts and relies on the other to fulfill their obligations honestly and with integrity. In legal contexts, good faith is often considered when determining the validity of contracts or negotiations, and it can also be applied in personal relationships, business dealings, and various social interactions. Essentially, good faith means having a genuine intent to do what is right and fair, even if it requires sacrifice or compromise.
