What is it?
It is a legal duty and a standard of behavior, not a formal cause of action by itself. Good faith governs how contract parties perform, how fiduciaries exercise judgment, and how courts deal with ambiguous or open contract terms.
Quick answer
Good faith usually means honest, fair dealing in performing a contract. In contracts, it matters because even silent terms can leave one party able to destroy the deal's intended benefit. Before signing, check whether duties are defined and whether any discretionary power can be abused.
Definitions
An honest dealing standard applied to contracts, commercial transactions, and fiduciary relationships. It fills gaps in an agreement and stops a party from using contract terms to destroy the deal's intended benefit. Breach of this standard is called bad faith, and it can expose the wrongdoer to extra damages beyond a simple breach of contract.
On a playground, if you promise a friend half your sandwich, good faith means you actually cut it in half. Not good faith is offering the half while you keep a whole sandwich hidden in your backpack.
Term context
It is a legal duty and a standard of behavior, not a formal cause of action by itself. Good faith governs how contract parties perform, how fiduciaries exercise judgment, and how courts deal with ambiguous or open contract terms.
A party who acts in bad faith risks a breach of contract finding, extra damages, and in fiduciary settings a separate breach of duty claim. The party who concealed its intention and caused the harm bears the risk, not the honest side.
The duty code in when a contract is formed, it remains in place through performance, and it controls how a party performs terms that grant discretion. The duty also matters when an insurer decides a claim or a fiduciary administers trust property.
The phrase appears in UCC Article 2 sales contracts, commercial agreements, franchise and insurance documents, and in many trust agreements quite as an implied term of general contract law. Courts around the country read good faith into most written contracts.
Buyers and sellers owe a statutory version of good faith to each other in transactions. Insurers owe shopping; policyholders, franchisees owe fair dealing to franchisors, and a trustee or corporate officer owes a strict duty of good faith to those whose money or right is held.
First, determine whether the relationship is commercial under UCC Article 2 or purely a common law contract, because the standard is defined slightly differently. Then gather the conduct surrounding the disputed term, including the party's honesty and any hidden motive for contact. At trial, the factfinder can compare that conduct to commercial standards and the contract's purpose, and the court can strip a bad faith benefit from the party expecting the contract.
Contract relevance
A party who acts in bad faith risks a breach of contract finding, extra damages, and in fiduciary settings a separate breach of duty claim. The party who concealed its intention and caused the harm bears the risk, not the honest side.

| Seller | Make sure the buyer's forecast is not selectively low and that buyer's rejection rejection has a good faith reason rather than to avoid a price adjustment. |

Missing or vague
If the contract never mentions good faith, a party can use a loophole to cause a commercial loss without violating the plain text.\nThe court fills the gap under an implied duty, but that leads to expensive discovery about what each party actually intended.\nWhen discretion covers pricing, quantities or approvals, the absence of a clear duty creates a big risk of the contract being used as option one side.\nSome judges still read good faith into every contract, while other judges do not define it at all, so litigation outcomes become unpredictable.\nSignature over a written standard of faith between ordinary parties is what reduces the risk.
Document map
| Contract section | What to inspect |
|---|---|
| Definitions | See whether good faith is specifically defined as an objective standard, subjective honest belief, honesty in fact, or a combination of the two. |
| Discretionary clauses | Look for terms that grant a party approval, expect condition or "in its own" and then see whether the good faith language reaches. |
| Payment and adjustments | Verify that the payments and price levels and the adjustment provisions can be implemented only within the good faith business reasons, not to punish resources. |
| Termination | Contracts that allow for any good faith termination are weak to arbitrate. Demand that terminating reasons be stated in the notice and be objective. |
| Dispute resolution | Confirm how a judge or arbitrator can check whether good faith was used in decision-making and whether the mental health of the decision is in dimensions. |
