Good faith law is the body of rules requiring parties to a contract, an insurance policy, a corporate board seat, or a property transaction to deal honestly with each other and not undermine what the other side was promised. The duty is implied into nearly every enforceable agreement in the United States, whether or not the word appears in the document. Courts apply it most forcefully in insurance disputes, corporate governance cases, and any situation where one party holds discretion the other is depending on.
What the Duty Actually Requires
Two sources create the baseline. Under UCC § 1-304, every contract governed by the Uniform Commercial Code carries an obligation of good faith in both performance and enforcement.1Legal Information Institute. Uniform Commercial Code 1-304 – Obligation of Good Faith Outside the UCC, the Restatement (Second) of Contracts § 205 imposes the same duty on all contracts. Between them, they cover commercial sales, service contracts, insurance policies, and employment arrangements.
The practical effect: you cannot use technicalities or silence in a contract to strip the other side of what they reasonably expected to receive. If a distribution agreement lets one party set prices, that party cannot set prices so high the other side can never make a sale. The letter of the contract might permit it, but the implied covenant does not. Courts treat the covenant as a gap-filler. When the written terms don’t address a specific behavior, the covenant supplies the expectation that neither side will act to destroy the other’s benefit of the bargain.
Two features surprise people. The duty cannot be waived. UCC § 1-302(b) states that the obligations of good faith prescribed by the code “may not be disclaimed by agreement.”2Legal Information Institute. Uniform Commercial Code 1-302 – Variation by Agreement Parties can agree on how to measure good faith, but they cannot eliminate the obligation. And the covenant does not create a standalone lawsuit. A failure of good faith is treated as a breach of the specific contract duty it relates to, not as a separate claim floating on its own. You still need to point to an actual contract term or obligation that was violated through bad-faith conduct.
How Courts Decide Whether Someone Acted in Good Faith
The UCC defines good faith as “honesty in fact and the observance of reasonable commercial standards of fair dealing.” That two-part definition gives courts both a subjective and an objective lens.
The subjective test asks what the person actually believed. A party who sincerely thought their actions were proper can satisfy this test even when the belief was unreasonable. Sincerity alone can be enough.
The objective test asks what a reasonable person in the same industry would have done. It doesn’t care about the individual’s belief. If the conduct fell below accepted commercial norms, it fails the objective standard regardless of the person’s intentions. A wholesale buyer who manipulates inspection results to force a price reduction might genuinely believe they’re being clever rather than dishonest, but the behavior still falls short of reasonable commercial standards.
Either test can sink a claim of good faith. The subjective test catches deliberate dishonesty. The objective test catches conduct no reasonable businessperson would consider fair, even if the person doing it didn’t realize they were out of bounds.
Good Faith in Contract Discretion
Most good faith disputes reach court through discretion clauses. Many contracts give one party the power to make decisions that affect both sides: setting performance benchmarks, determining whether a condition has been met, choosing whether to renew. The implied covenant requires that this discretion be exercised within the reasonable expectations the parties had when they signed the deal. Use it arbitrarily or to punish the other side, and you have a breach.
The test isn’t whether the contract allowed the action in isolation. It is whether the action destroyed the purpose the other side was counting on. Courts look past the literal permission in the text to what the parties bargained for.
Good Faith in Insurance Claims
Insurance is where good faith obligations bite hardest, because the insurer holds nearly all the power. The policyholder pays premiums and submits claims; the insurer decides whether to pay. That imbalance creates a heightened duty of good faith that goes beyond ordinary contract obligations.
First-Party Claims
A first-party bad faith claim arises when your own insurance company mistreats you. You file a claim under your homeowner’s, health, or auto policy, and the insurer unreasonably denies it, delays payment, or offers far less than the claim is worth. To prove first-party bad faith, you need to show the insurer denied or underpaid benefits owed under your policy and that the conduct was unreasonable or without proper cause. The insurer must investigate thoroughly before deciding; a denial based on a superficial review or a made-up justification is the textbook example.
Third-Party Claims
Third-party bad faith involves the at-fault party’s insurer. When you’re sued and your liability insurer has a duty to defend you, the company must hire competent counsel and manage the case to protect your interests, not just its own bottom line. The duty to defend means the insurer must provide a legal defense whenever a lawsuit alleges conduct that could fall within your policy’s coverage. The duty to settle means the insurer must seriously consider settlement offers within your policy limits when liability is reasonably clear. Walking away from a reasonable settlement offer to save money is one of the most common triggers for bad faith liability, because it exposes you to a judgment that exceeds your coverage.
What You Can Recover
When an insurer acts in bad faith, the consequences go well beyond paying the original claim. In a first-party case, you can recover the policy benefits that were wrongfully withheld, plus additional financial losses caused by the delay or denial, and in many states, compensation for emotional distress. In a third-party failure-to-settle case, the insurer can be held responsible for the entire excess judgment above the policy limits.
Most states also allow punitive damages in bad faith cases, though the standard of proof is higher than for ordinary claims. You typically need to show the insurer’s conduct was malicious, fraudulent, or showed a conscious disregard for your rights. Filing deadlines for a bad faith lawsuit vary widely by jurisdiction and depend on whether the claim is treated as a contract action or a tort.
Good Faith in Employment
Employment is where good faith law gets thinnest. Most workers in the United States are employed at will, meaning either side can end the relationship for nearly any reason. Only about eleven states recognize the implied covenant of good faith and fair dealing as a meaningful limit on at-will termination.3U.S. Bureau of Labor Statistics. The Employment-at-Will Doctrine: Three Major Exceptions In those states, the covenant has been read to bar firing someone in bad faith or out of malice, particularly when the timing deprives the worker of earned compensation.
The classic scenario: an employee is about to vest in a retirement benefit or earn a large commission, and the employer terminates them right before the payout date. In the states that recognize the covenant, that timing alone can support a claim. Employees who prove the breach can recover back pay or the value of lost benefits.
Even in states that don’t recognize the covenant in employment, the public policy exception is a separate protection. Employers everywhere face legal exposure for firing workers who exercise legal rights like filing a workers’ compensation claim, who perform civic duties like jury service, who report illegal activity, or who refuse to carry out unlawful instructions. The public policy exception doesn’t require proving bad faith; it turns on whether the termination violates a clearly established legal or constitutional principle.
Good Faith Purchasers of Goods and Land
Good faith also protects buyers. Under UCC § 2-403, a person who holds voidable title to goods can transfer full ownership to a good faith purchaser for value.4Legal Information Institute. Uniform Commercial Code 2-403 – Power to Transfer; Good Faith Purchase of Goods This applies even when the original seller was deceived about the buyer’s identity, the payment check later bounced, or the goods were obtained through fraud. If you buy those goods honestly and pay a fair price without knowing about the earlier problem, you keep them. The original owner’s remedy runs against the person who deceived them, not against you.
Recording statutes extend a similar principle to real property. A bona fide purchaser who buys land for value, without notice of a prior unrecorded claim, generally takes priority over the earlier claimant. The details differ by jurisdiction, but the core rule is the same: honest buyers who do their due diligence outrank prior claimants who failed to put the world on notice of their interest.
Good Faith for Corporate Directors
Corporate directors owe a fiduciary duty of good faith as part of their broader duty of loyalty to the company. Under the business judgment rule, courts will generally defer to a board’s decisions if the directors acted in good faith, exercised the care a reasonably prudent person would use, and reasonably believed they were acting in the corporation’s best interests.5Legal Information Institute. Business Judgment Rule That deference disappears when a plaintiff shows the director acted in bad faith.
Bad faith in the corporate context doesn’t require proof that a director tried to personally profit at the company’s expense. Intentionally ignoring known legal compliance problems, consciously failing to monitor the business, or approving a transaction the director knows serves no corporate purpose can all qualify. Directors must make good-faith efforts to ensure the company has compliance policies and to oversee management’s adherence to them. The duty isn’t to be right about every decision. It is to actually try to serve the company’s interests rather than acting with indifference or an ulterior motive.
Good Faith Before a Contract Exists
American law generally does not impose a duty to negotiate in good faith before a binding agreement exists. You can walk away from negotiations for any reason, even after extensive discussions, without owing the other side anything. The freedom to say no is treated as essential to meaningful consent.
The exception arises when parties sign a preliminary agreement, like a letter of intent or term sheet, that expressly commits them to negotiate remaining terms in good faith. Some states enforce those commitments. Others refuse to, on the ground that “negotiate in good faith” is too vague for a court to police. Where they are enforced, breaching the obligation can lead to damages, though the measure varies. Some jurisdictions limit recovery to the costs the non-breaching party actually spent on negotiations. Others allow expectation damages if the court concludes the parties would have reached a deal but for the breach. If you sign a preliminary agreement with a good-faith negotiation clause, treat it as binding until you confirm otherwise with a lawyer familiar with your jurisdiction’s approach.
