Can you sue your lawyer for a conflict of interest?

A lawyer owes you undivided loyalty. That is part of the lawyer's fiduciary duty, the highest duty the law recognizes. ABA Model Rule 1.7 defines a concurrent conflict as one where representing you will be directly adverse to another client, or where "there is a significant risk" that the representation will be materially limited by the lawyer's duties to another client, a former client, a third person, or the lawyer's own interest.

Under ABA Model Rule 1.7(b), a lawyer may proceed despite a conflict only if the lawyer reasonably believes they can represent each client competently and diligently and each affected client gives informed consent, confirmed in writing. Some conflicts cannot be waived at all, such as one client suing another client the same lawyer represents in the same case.

Rule 1.8 lists specific traps. A lawyer may not enter a business deal with a client unless the terms are fair, fully disclosed in writing, the client is advised in writing to get independent advice, and the client consents in a signed writing. A lawyer may not draft a will or other document giving themselves a substantial gift from a non-relative client. A lawyer may not accept payment from someone else unless you consent and there is no interference with the lawyer's judgment. And a lawyer representing several clients may not make an aggregate settlement without each client's written, informed consent.

Real-world examples:

• One lawyer represents both drivers in a car crash, then settles in a way that shortchanges one of them.
• A lawyer borrows money from an elderly client or sells the client an interest in a venture.
• An estate lawyer drafts a will naming themselves as a beneficiary.
• A divorce lawyer is quietly forming a firm with the other spouse's lawyer.

Other Rule 1.8 red flags

Rule 1.8 also bars several arrangements that clients rarely recognize as conflicts. A lawyer may not ask you to agree in advance to limit the lawyer's liability for malpractice unless you had your own independent lawyer for that agreement. A lawyer may not settle a malpractice claim with you, while you are unrepresented, without advising you in writing to get independent counsel and giving you a reasonable chance to do so. A lawyer generally may not acquire an ownership interest in the lawsuit itself, apart from a lien for fees or a reasonable contingency fee in a civil case. And a lawyer may not begin a sexual relationship with a current client. Under ABA Model Rule 1.8(k), a conflict under paragraphs (a) through (i) of Rule 1.8 that applies to one lawyer in a firm applies to every lawyer in that firm.

Lawyers deal with potential conflicts constantly, and disclosing one and getting consent is the system working. A conflict becomes a legal claim when the lawyer hid it, minimized it, or let it change what they did for you.

A leading example is Stanley v. Richmond (California Court of Appeal, 1995). A wife's divorce lawyer was in the process of forming a new firm with the lawyer representing her husband. The lawyer then led her into a settlement in which she gave up her entire interest in her husband's pension. She later learned that keeping even a $1 interest would have made her eligible for low-cost lifetime federal health insurance. The trial court threw out her case, but the Court of Appeal reversed, holding she had made out a prima facie case for breach of fiduciary duty, negligence, and breach of contract. In Stanley v. Richmond, a divorce client who gave up a pension interest while her lawyer was forming a firm with her husband's lawyer was allowed to take her fiduciary duty claim to a new trial.

It is usually not an actionable conflict when:

• The lawyer disclosed the relationship in writing and you agreed to proceed.
• The "conflict" is simply that the lawyer wanted to get paid. Every fee arrangement creates some tension, and courts do not treat that alone as disloyalty.
• The relationship was trivial, such as knowing the other lawyer from bar events.
• The outcome was the same one a conflict-free lawyer would likely have achieved, and the breach was not serious.

Conflict cases are usually pleaded as breach of fiduciary duty, sometimes alongside ordinary negligence. The elements typically are: a lawyer-client relationship, a breach of the duty of loyalty, and harm caused by the breach or a benefit to the lawyer. For compensatory damages, most courts require the same causation proof as in any bad advice case: that without the conflict, you would have gotten a better result.

That often means a version of the case within a case, and an expert witness on both legal ethics and the value of your underlying matter. In Stanley, the plaintiff called a legal ethics expert to testify that the lawyer had a conflict.

There is an important exception for the fee. In Burrow v. Arce (Texas Supreme Court, 1999), the court held a client can obtain forfeiture of a lawyer's fee for breach of fiduciary duty without proving the breach caused actual damages. The court explained that the purpose of forfeiture is to protect relationships of trust by discouraging disloyalty, not to compensate. The breach must be clear and serious, and the amount forfeited is decided by the judge, not the jury. See our breach of fiduciary duty page for more.

Damages in conflict cases come in three forms, and you may seek more than one:

Remedy	What it covers	Proof needed
Compensatory damages	The better result you lost	Causation, usually a case within a case
Fee forfeiture	Some or all fees paid	Clear, serious breach (varies by state)
Disgorgement	Profits the lawyer made from the conflict	The lawyer's gain
Punitive damages	Punishment for intentional misconduct	Fraud or malice, per state law

The Texas court in Burrow listed factors for deciding how much of a fee to forfeit: the gravity and timing of the violation, its willfulness, its effect on the value of the lawyer's work, any other threatened or actual harm, and the adequacy of other remedies. Fee forfeiture can be total or partial, and in Texas the judge, not the jury, sets the amount. Not every state follows Burrow. Some require proof of actual injury before any fee is returned, so how much a conflict claim is worth depends heavily on where you live.

Conflict claims are often subject to the same statute of limitations as other malpractice claims, even when framed as breach of fiduciary duty. California's Code of Civil Procedure section 340.6 applies its one-year-from-discovery, four-year outer limit to any wrongful act or omission by a lawyer in performing professional services, other than actual fraud. New York's CPLR 214(6) gives three years for malpractice regardless of whether the claim is based in contract or tort.

Conflicts are often hidden, so the discovery rule matters: the clock may not start until you knew or should have known about the conflict. California also tolls the four-year period while the lawyer willfully conceals the facts. Some states give fiduciary duty claims a longer period than negligence. Check the rules for your state on the statute of limitations table.

1. Ask in writing. ABA Model Rule 1.4 requires a lawyer to promptly comply with reasonable requests for information. Ask directly whether the lawyer has any relationship with the other side.
2. Get your file and every signed document, including waivers.
3. Consider new counsel before signing any settlement the conflicted lawyer negotiated.
4. File a bar grievance if the conduct was serious, even if you do not sue. A bar grievance can lead to discipline but not money. See malpractice versus a bar complaint.
