Legal malpractice in Texas — the suit within a suit, and the Hughes tolling rule
A claim in Texas district and county courts · Last verified August 26, 2026
Legal malpractice in Texas is a negligence claim with two features that make it much harder than it sounds. You must prove the suit within a suit — that you would have won the underlying case and could have collected on it. And the anti-fracturing rule stops you from dressing the same complaint up as fraud, breach of fiduciary duty, or a DTPA claim to reach better remedies.
The one rule that runs in a client's favour is Hughes tolling: where the malpractice happened in litigation, the limitations clock does not run while that litigation is on appeal.
What the claim is
Your lawyer handled your matter negligently and it cost you money or a case you should have won.
Where the right comes from
Common law negligence, with the elements stated in Cosgrove v. Grimes, 774 S.W.2d 662 (Tex. 1989).
What a plaintiff has to prove
- A duty — an attorney-client relationship.
- Breach of the standard of care of a reasonably prudent attorney.
- Proximate cause of the injury.
- Damages.
Cosgrove, 774 S.W.2d at 665.
The suit within a suit
Where the malpractice occurred in litigation, causation requires proving the case within the case: that but for the lawyer's negligence, you would have obtained a better result, and — in most formulations — that the judgment would have been collectible.
That last requirement kills a great many claims. A missed deadline against a defendant with no assets and no insurance costs the client nothing the law will compensate.
Expert testimony is required on the standard of care and its breach, except in the rare case where the negligence is within a layperson's common understanding.
How long you have to file
Two years, under CPRC § 16.003(a).
The Hughes rule tolls it. Hughes v. Mahaney & Higgins, 821 S.W.2d 154 (Tex. 1991), holds that where an attorney commits malpractice in the prosecution or defense of a claim that results in litigation, limitations are tolled until all appeals on the underlying claim are exhausted, or the litigation is otherwise finally concluded.
The reason is practical: a client forced to sue their lawyer while the underlying appeal is pending would have to argue the case was lost and winnable at the same time.
Hughes does not extend to transactional malpractice. Intermediate courts have declined to apply it to a botched contract, a defective conveyance or a failed tax structure, and the Texas Supreme Court has not extended it there.
The discovery rule also applies to legal malpractice, deferring accrual until the client knew or should have known of the injury.
What has to happen before you file
Nothing. Texas imposes no certificate of merit and no expert report requirement for legal malpractice — a striking difference from health care liability claims and from claims against design professionals.
What the claim pays
The value of what was lost — the collectible judgment forgone, the settlement that should have been obtained, the fees and costs wasted.
Fee forfeiture, where the conduct is a genuine breach of fiduciary duty rather than negligence (Burrow v. Arce, 997 S.W.2d 229 (Tex. 1999)).
Exemplary damages only on independent proof of fraud or malice, not from negligence alone.
No attorney's fees for a legal malpractice claim.
Who can be sued
The lawyer and the firm, on ordinary principles of vicarious liability.
Only by a client. Texas requires privity: Barcelo v. Elliott, 923 S.W.2d 575 (Tex. 1996), holds that a lawyer owes no duty to a non-client, and disappointed will beneficiaries cannot sue the drafting attorney. The narrow exception is a negligent misrepresentation claim under McCamish, where the lawyer supplied information knowing a non-client would rely on it.
Common defenses
- The anti-fracturing rule. A client cannot divide one negligence claim into fraud, breach of fiduciary duty, DTPA and breach of contract claims to reach fee shifting and punitive damages. Texas courts recharacterise them back into a single malpractice claim.
- No causation — the underlying case would have been lost anyway, or the judgment would not have been collectible.
- Judgmental immunity. A lawyer is not liable for an error in judgment on an unsettled point, where the decision was made in good faith after reasonable investigation.
- The Peeler doctrine. Peeler v. Hughes & Luce, 909 S.W.2d 494 (Tex. 1995), bars a convicted criminal defendant from suing defense counsel for malpractice unless the conviction has been overturned or the defendant otherwise exonerated.
- No privity, for a non-client plaintiff.
- Limitations, subject to Hughes tolling and the discovery rule.
What people get wrong
Losing is not malpractice. The client must prove the case was winnable and would have been won but for the lawyer's negligence.
Collectibility matters. A perfect liability case against a defendant with nothing to take is worth nothing in a malpractice suit.
You cannot fracture the claim. Adding a DTPA count to reach mandatory fees is the standard move, and Texas courts strike it.
Hughes tolling is narrower than it looks. It applies to litigation malpractice. Transactional malpractice runs on the ordinary two-year clock with the discovery rule.
Where it came from
Cosgrove fixed the elements in 1989, adopting a reasonably-prudent-attorney standard rather than a locality rule.
Hughes followed in 1991 with the tolling rule, built on the observation that requiring a client to sue during the underlying appeal would force inconsistent positions and waste judicial resources.
Peeler in 1995 closed the door on criminal-defense malpractice absent exoneration, reasoning that a convicted defendant's own conduct is the cause of the conviction. And the anti-fracturing rule developed through the 1990s and 2000s as clients tried to convert negligence into claims with better remedies — a pattern the courts of appeals now police consistently.
Common questions
How long do I have to sue my lawyer in Texas?
Two years, tolled while the underlying litigation and its appeals are pending if the malpractice occurred in that litigation.
Do I need an expert?
Almost always, on the standard of care and its breach. There is no pre-suit expert report requirement, but you cannot try the case without expert testimony.
Do I have to prove I would have won?
Yes. The suit within a suit is the causation element, and in most cases you must also show the judgment would have been collectible.
Can I recover attorney's fees?
No.
Can I sue my lawyer for fraud or under the DTPA instead?
Usually not. The anti-fracturing rule recharacterises those claims as a single malpractice claim.
I was convicted and my lawyer was terrible. Can I sue?
Not unless the conviction has been overturned or you have otherwise been exonerated.
