Definitions
What is good faith?
Legal Definition
Good faith demands honest, reasonable conduct in contractual dealings, preventing parties from acting deceitfully or undermining the agreement's purpose. It obligates each side to cooperate and refrain from sabotage, creating enforceable duties under UCC § 1-304 and the Restatement (Second) of Contracts. Courts often scrutinize the “no‑reasonable‑grounds‑to‑believe‑the‑other‑party‑will‑benefit” qualifier.
Plain-English Translation
Imagine a hall pass that says you must stay in class and not wander; breaking that promise means the teacher can revoke the pass.

Missing or vague
If good faith is missing or vague
Without a clear good‑faith provision, parties may argue over what constitutes reasonable conduct.
Disputes often center on whether a delayed shipment was a legitimate business decision or a breach.
Courts will look to extrinsic evidence, increasing litigation costs and uncertainty.
The party claiming breach bears the burden of proving bad faith, which can be costly.
Vague language invites divergent interpretations and potential contract termination.
