Constructive Fraud in California: Breach of Duty Without Intent to Deceive

Last updated: November 2026

Constructive fraud in California is a breach of duty that, without any actual intent to deceive, gains an advantage for the person at fault by misleading another to their prejudice. (Civ. Code, § 1573.) It applies where one party owes the other a duty of trust, such as between partners, LLC managers and members, or an agent and principal. A California business owner misled by a fiduciary does not have to prove the fiduciary meant to lie. Kolmogorov Law, P.C. handles constructive fraud claims in Orange County and Los Angeles.

What Civil Code 1573 says

The statute defines constructive fraud two ways. The first is a breach of duty that, "without an actually fraudulent intent," gains an advantage for the person at fault by misleading another to his prejudice. (Civ. Code, § 1573, subd. 1.) The second is any act or omission the law specially declares fraudulent, regardless of actual fraud. (Civ. Code, § 1573, subd. 2.)

Compare actual fraud, which requires acts committed "with intent to deceive." (Civ. Code, § 1572.) Constructive fraud removes that element and replaces it with a duty. A stranger who misleads you without intent is at most negligent. A fiduciary who does the same has committed constructive fraud, because the relationship itself obligated candor.

The firm's fraud claims page covers intentional fraud. This page stays on the duty-based version.

Who owes the duty

The claim lives or dies on whether a fiduciary or confidential relationship existed. In business cases the common ones are statutory.

Partners owe each other a duty of loyalty and a duty of care. The duty of loyalty includes accounting to the partnership for any profit or benefit derived from partnership business or property, and refraining from dealing with the partnership on behalf of an adverse interest. (Corp. Code, § 16404, subds. (a), (b).)

In a member-managed LLC, members owe the company and each other the same two duties, with the duty of loyalty defined in similar terms. (Corp. Code, § 17704.09, subds. (a), (b).) In a manager-managed LLC, those duties fall on the managers, and a member generally has no fiduciary duty solely by reason of being a member. (Corp. Code, § 17704.09, subd. (f)(3).) That distinction decides many cases.

Corporate directors and officers, agents, and trustees also owe fiduciary duties. Ordinary buyers and sellers, lenders and borrowers, and arm's-length contracting parties usually do not. Our fiduciary duty guide covers the relationships in more depth.

How it comes up for business owners

The managing partner who shades the numbers. One partner runs the books. When the other asks how the year went, he says "about break-even" and leaves out that he paid himself a bonus from the operating account. He may believe the bonus was earned. The omission still misled a partner to her prejudice, and the duty to disclose was his.

The LLC manager who buys the company's asset. A manager arranges for the LLC to sell equipment to an entity he controls at a price he calls "fair market." He never tells the members about his interest in the buyer. Even if the price was defensible, the undisclosed self-dealing is the breach.

The agent who takes the better deal. A broker engaged to sell a business receives two offers and presents only the one from a friend, calling it the best available. The seller accepts. Intent to harm the seller is not required; the nondisclosure in a relationship of trust is enough.

Elements of constructive fraud in California

In practice, a constructive fraud plaintiff proves four things:

A fiduciary or confidential relationship.
A misleading statement or a nondisclosure by the fiduciary.
Reliance by the plaintiff.
Resulting harm.

The plaintiff does not prove knowledge of falsity or intent to deceive. That changes litigation strategy. In an actual fraud case, the defendant's emails about what he knew are the battleground. In a constructive fraud case, the battleground is the relationship and the advantage gained. Those questions are usually answered by bank records and corporate documents rather than by intent evidence.

The claim is frequently pleaded alongside breach of fiduciary duty and a demand for an accounting. The accounting cause of action is the tool for finding out what the fiduciary actually did with the money.

Remedies and limits

A plaintiff recovers the loss caused by the breach, and courts have broad equitable power in fiduciary cases, including disgorgement of the advantage the fiduciary gained and rescission of a tainted transaction. A partner's duty to hold as trustee any benefit derived from partnership business supports that remedy directly. (Corp. Code, § 16404, subd. (b)(1).)

Punitive damages are harder. They require clear and convincing evidence of oppression, fraud, or malice, and the statute defines fraud as an intentional misrepresentation or concealment. (Civ. Code, § 3294, subds. (a), (c)(3).) The claim by definition lacks intent, so a plaintiff who wants punitive damages usually needs to prove that the concealment was in fact deliberate.

On timing, an action for relief on the ground of fraud or mistake must be brought within three years of discovery of the facts. (Code Civ. Proc., § 338, subd. (d).) Courts have generally applied that period to constructive fraud, though the characterization of a claim can be contested, so the safe course is to file early.

What we do, and where these cases are heard

We start with the relationship: the partnership agreement, the operating agreement, the engagement letter. Then we trace the advantage through bank statements and related-party transactions. Where a partner has taken money, our page on what to do when a business partner steals covers the immediate steps.

We also defend these claims. The most effective defenses are that no fiduciary relationship existed, or that the transaction was fully disclosed and approved as the governing agreement required.

Cases are filed in the Superior Court: for Orange County, the Central Justice Center in Santa Ana; for Los Angeles, the Stanley Mosk Courthouse. The partnership and LLC disputes hub and the business fraud hub describe the related practice.

What to bring to the first meeting

The document that created the relationship: partnership agreement, operating agreement, bylaws, or engagement letter. Financial statements and tax returns for the relevant years. Bank statements if you have access. Any written communications in which the fiduciary described the finances or a transaction, and a list of transactions you now believe were not disclosed.

Frequently asked questions

What is constructive fraud in California?

It is a breach of a fiduciary or confidential duty that misleads another person to their prejudice and gains an advantage for the person at fault, without any intent to deceive. Civil Code section 1573 defines it.

What is the difference between actual fraud and constructive fraud?

Actual fraud requires intent to deceive or to induce a contract. Constructive fraud does not. Instead it requires a relationship of trust, such as partner to partner or manager to LLC member, in which the defendant had a duty to disclose and failed to. It is easier to prove but generally does not support punitive damages.

Can I sue my business partner for constructive fraud?

Usually, yes, if the partner failed to disclose something a partner must disclose and gained an advantage from it. Partners owe each other statutory duties of loyalty and care under Corporations Code section 16404. In a manager-managed LLC, the duty runs from the managers, not from passive members, so the structure matters.

How long do I have to file a constructive fraud claim?

Three years from discovery of the facts is the period California applies to fraud-based claims, and courts have generally applied it to constructive fraud. Discovery is measured from when you knew or should have known, so a partner who had access to the books may face an earlier start date. File early.
