Can you sue your lawyer for bad legal advice?

Much of what lawyers do is advise: whether you have a claim, what a contract means, what a divorce settlement will cost you, whether to accept a plea. ABA Model Rule 1.4(b) requires a lawyer to explain a matter to the extent reasonably necessary to permit the client to make informed decisions about the representation. Rule 1.1 requires the legal knowledge, skill, thoroughness, and preparation reasonably necessary for the work.

Negligent advice usually takes one of these forms:

• Wrong on settled law, such as telling a client an asset is separate property when the law clearly says otherwise.
• No research on a question the lawyer did not know, followed by a confident but unsupported answer.
• Missing warnings, such as failing to mention a deadline, a tax consequence, or a right you were giving up.
• Telling you that you have no case without enough inquiry, then not warning you about the time limit to get a second opinion.
• Transactional errors in explaining what a contract or deal does. See drafting errors.

Insurers' data shows how common this is. The ABA's 2016 profile of legal malpractice claims found that failure to know or properly apply the law was the single most common error, at 15.38 percent of claims, and the 2016 to 2019 edition reported that substantive legal errors made up roughly half of all claims. See legal malpractice statistics.

The key case is Smith v. Lewis (California Supreme Court, 1975). A divorce lawyer told his client that her husband's state and federal retirement benefits were not community property, so they were left out of the divorce. The court found he had done no reasonable research on the point, and upheld a $100,000 jury verdict. The court also drew the line that still applies in most states.

Under Smith v. Lewis, a lawyer does not guarantee the soundness of every opinion, but must know the plain and elementary principles of law and discover rules that can be readily found by standard research techniques. If the law on a point is genuinely doubtful or debatable, the lawyer is not liable for failing to anticipate how courts will resolve it. But even in an unsettled area, the court said, the lawyer must do reasonable research and make an informed decision.

That protection is often called the attorney judgment rule. It is usually not malpractice when:

• The law was genuinely unsettled, and the lawyer researched it and made a reasonable call.
• The lawyer recommended one reasonable strategy over another, and it did not work.
• The lawyer predicted an outcome that did not happen, such as a jury verdict or judge's ruling.
• You were warned about the risk and chose to proceed anyway.

As the Smith court quoted, there is nothing strategic or tactical about ignorance. For more on these gray areas, see what is not legal malpractice.

Advice outside what the lawyer agreed to handle

Lawyers can agree to handle only part of a problem. ABA Model Rule 1.2(c) allows a lawyer to limit the scope of a representation only if the limitation is reasonable under the circumstances and the client gives informed consent. A limited engagement can narrow what advice the lawyer owed you, so your engagement letter matters. But limits have edges. The comment to Rule 1.3 says that when a lawyer handled a proceeding that ended badly and the two of you never agreed about an appeal, the lawyer must consult with you about the possibility of appeal before relinquishing responsibility. And the comment says doubt about whether the relationship still exists should be clarified by the lawyer, preferably in writing.

You need the standard elements of malpractice, with a twist on causation:

1. A lawyer-client relationship, which can arise from a single consultation if you reasonably relied on the advice.
2. Advice that fell below the standard of care, usually shown by an expert witness.
3. Reliance and causation: with correct advice, you would have made a different choice, and that choice would have produced a better result.
4. Damages you can measure.

Causation is where most bad advice claims are fought. It is the case within a case, applied to a decision rather than a trial. In Togstad, the jury specifically found that, but for the lawyer's negligent advice, the clients would have been successful in a lawsuit against the doctor. In a deal or transaction, you typically must prove that a better deal was actually available, not just that the one you got was bad.

Your own testimony about what you would have done matters, but courts look for corroboration: notes of what you asked, other options you were weighing, and whether the correct advice would have been realistic to follow. If you would have made the same choice anyway, the bad advice did not cause your loss.

Damages are the difference between where you ended up and where correct advice would have put you. In Smith v. Lewis, damages were measured by the value of the client's lost community share of retirement benefits, supported by an economist's testimony about the present value of the pensions over the husband's roughly 29-year life expectancy.

Advice error	Typical measure
Told you had no case	Value of the claim you did not bring
Wrong on property or divorce law	Value of the share you gave up
Missed tax consequence	Extra tax, penalties, and interest
Bad deal advice	Loss compared with a better available deal

States differ on some elements, such as whether punitive damages lost in the underlying case can be recovered (California says no) and whether emotional distress is ever recoverable. See what a legal malpractice case is worth.

Bad advice is often discovered long after it was given, when a tax bill arrives or a court rules the other way. Many states apply a discovery rule, and some require that you suffer actual injury before the clock runs. California's section 340.6 tolls its four-year outer limit while the plaintiff has not sustained actual injury and while the lawyer continues representing the client on the same matter. New York gives three years under CPLR 214(6).

Because the start date can be disputed, do not wait. Check your state on the statute of limitations table.

1. Write down exactly what you were told, when, and by whom, and gather any written advice.
2. Get a second opinion on the underlying question, and ask whether anything can still be fixed.
3. Get your file, including any research memos. See how to get your case file.
4. Document your losses and the decision you would have made with correct advice.

Fixing the damage can shrink the claim

Sometimes bad advice can still be undone: a return can be amended, a deal renegotiated, a motion filed, or a new claim brought before a deadline runs. Courts generally expect people to take reasonable steps to limit their losses, and the cost of fixing the problem is often part of what you can recover. A second opinion within days of spotting bad advice can preserve options that disappear once a deadline passes, as the one-year delay in Togstad shows. Talk to a new lawyer about both the fix and the claim at the same time.
