Implied Covenant of Good Faith and Fair Dealing in California

In California, the implied covenant of good faith and fair dealing is an obligation the law attaches to every contract, requiring each side to avoid doing anything that would deprive the other of the benefits they bargained for. It applies whether your agreement is written, oral, or formed by conduct, and neither party can waive it. When someone stays inside the literal wording of a contract while working to defeat its purpose, that’s the conduct the covenant is designed to catch.

What the Covenant Requires

The statutory footing sits in California Civil Code sections 1655 and 1656, which provide that terms necessary to make a contract reasonable or to carry it into effect are implied automatically.¹² California courts have built on these statutes to establish that neither party will do anything to injure the other’s right to receive the agreement’s benefits.³

The covenant doesn’t add new obligations to your contract. It protects the ones already there. When an agreement gives one party discretion over price, timing, approvals, or performance standards, the covenant requires that discretion to be exercised reasonably and honestly rather than as a weapon to strip value from the other side. Think of it as a guardrail: the express terms tell each party what to do, and the covenant prevents either side from gaming those terms in bad faith.

You cannot contract around it. For transactions governed by the Uniform Commercial Code, California Commercial Code section 1304 imposes a parallel good faith duty on performance and enforcement, and parties cannot disclaim it.⁴

What You Have to Prove

California’s standard jury instruction on this claim (CACI No. 325) breaks it into six elements. To win, you need to show all of them:³

You and the other party entered into a contract, written, oral, or implied by conduct.
You did everything (or substantially everything) the contract required of you, or you were excused from performing.
Any conditions the contract required before the other party had to perform either occurred or were excused.
The other party did something specific that prevented you from receiving what the contract promised.
That conduct was not done fairly and in good faith.
You suffered actual harm as a result.

The fifth element is where most cases are won or lost. Failing to perform a duty is an ordinary breach of contract. To cross into a covenant violation, the conduct needs to show something more: an intent to frustrate the deal, dishonesty, or an unreasonable use of discretion designed to deny you the benefit you expected.

How to Tell a Covenant Violation From an Ordinary Breach

A contractor who runs late has breached the contract. A contractor who deliberately does poor work to force you into paying for a bigger scope has violated the covenant. The distinction is between failure to perform and active interference with the other party’s expected benefits.

The patterns courts see most often include:

Abusing contractual discretion. If your contract lets one party set a price, determine quantities, or approve conditions, using that power dishonestly or unreasonably to strip the other side of its bargain violates the covenant.
Deliberate non-cooperation. Withholding required approvals, ignoring information requests, or dragging out processes so the other side can’t perform.
Manipulating performance standards. Intentionally delivering flawed performance or engineering conditions that make it impossible for the other party to meet their obligations.
Insurance claim stonewalling. An insurer failing to investigate, denying coverage without a reasonable basis, or lowballing a settlement to pressure a policyholder into accepting less than the claim is worth.⁵
Lender bad faith. Calling a loan on a minor technical default with no genuine business reason, or refusing reasonable restructuring where both sides would benefit.

The common thread is that the offender stays inside the literal words of the contract while gutting its purpose. Courts look at whether the conduct frustrated the reasonable expectations the parties had when they signed.

What You Can Recover

Contract Damages by Default

For most contracts, a covenant breach is treated as a breach of the contract itself, and your remedies are contract damages. The court aims to put you in the financial position you would have occupied if the contract had been performed properly. That can include lost profits, the cost of substitute performance, and other economic losses flowing from the conduct.³

If your damages are a fixed dollar amount or calculable from the contract’s terms, you can also recover prejudgment interest back to the day the money became due. For unliquidated damages, the court has discretion to award interest from the date you filed suit.⁶

The Insurance Exception

Insurance bad faith is the one major area where a covenant breach breaks out of the contract-damages box. Because the insurer–policyholder relationship carries a special duty, a bad faith denial or delay gives rise to a separate tort claim. Recovery can include emotional distress damages, and where the insurer’s conduct is oppressive or malicious, punitive damages are available. California Insurance Code section 790.03(h) lists the unfair claims practices that typically underlie these cases, including failing to investigate promptly, refusing to affirm or deny coverage in a reasonable time, offering substantially less than a claim is worth to pressure settlement, and forcing policyholders to sue to collect amounts clearly owed.⁵

This tort exception is narrow. The California Supreme Court held in Foley v. Interactive Data Corp. that tort remedies are not available for covenant breaches in employment contracts, and that limitation has generally kept tort recovery confined to the insurance setting.⁷ Employees who prove bad faith can recover contract damages only.

Attorney Fees

California follows the American Rule: each side pays its own attorney fees unless the contract says otherwise. If your contract has a fee provision, California Civil Code section 1717 makes it reciprocal, so the prevailing party recovers fees regardless of which side the clause originally named.⁸ Without such a clause, you eat your own legal costs even if you win. That’s worth checking before you commit to litigation, because fees in a contract fight can outrun the underlying damages quickly.

How Long You Have to Sue

Because a covenant claim is treated as a contract claim, the deadline turns on whether the contract is written or oral. You have four years from the date of the breach to file on a written contract,⁹ and two years on an oral contract.¹⁰

These deadlines are strict. Once the period runs, California law bars both lawsuits and arbitration on the claim.⁹ The clock usually starts on the date of the breach, though in cases involving fraud or concealment it may not run until you discovered, or reasonably should have discovered, the conduct.

Where the Covenant Stops

The covenant is powerful, and its limits matter just as much as its reach. It fills gaps; it does not rewrite the deal. You cannot use it to override express terms you agreed to, to add obligations the parties never contemplated, or to escape a bargain that simply turned out badly.

If your contract gives the other side an absolute right to do something, the covenant generally will not stop them from exercising it, even when the outcome hurts you. The covenant polices how discretion is used, not whether the discretion exists. A landlord with an unrestricted right to approve or reject subletting requests still has that right; the covenant requires only that the decision be made honestly rather than as a pretext.

The covenant also does not apply before a contract exists. During negotiations, there is no implied duty to bargain in good faith unless the parties have already signed a binding preliminary agreement that creates one. Walking away from a deal before signing, even after long negotiations, does not violate the covenant, because there is no contract yet for the covenant to attach to.
