When the lawyer defending your liberty was the one who cost it.

A conviction caused by your own attorney's negligence is a two-stage problem in New Jersey: undo the conviction first, then hold the lawyer accountable. We handle the second stage -- and we will tell you honestly whether it exists.

The order granting post-conviction relief runs four pages. Somewhere in the middle, a judge finds that your trial attorney never interviewed the alibi witness whose name you gave him at the first meeting, never requested the surveillance footage, never filed the suppression motion any competent defense lawyer would have filed. The conviction is vacated. The State dismisses rather than retry. You are out -- after three years you should never have served. The PCR order says, in the careful language courts use, that your lawyer failed you. The question you are asking now is whether that finding is worth anything beyond the freedom it restored.

Sometimes it is. New Jersey permits a former criminal defendant to sue negligent defense counsel for malpractice, and the state's rule on when that claim becomes available -- the exoneration rule of McKnight v. Office of the Public Defender -- is more plaintiff-friendly than the actual-innocence regimes other states use. But these are the hardest cases in the legal-malpractice field, with procedural gates that do not exist in personal-injury or family-law malpractice, and we would rather explain the gates honestly at the start than let you discover them at a summary-judgment hearing.

The conviction has to fall before the malpractice claim can stand.

In most legal-malpractice cases, the claim exists the moment the negligence causes measurable harm. Criminal cases work differently, and the reason is structural. So long as a criminal judgment stands unimpeached, the law treats the judgment -- not the lawyer -- as the cause of the incarceration, the record, and everything that flowed from them. A civil jury is not allowed to look behind a standing conviction and decide the defendant would have walked with a better lawyer.

The Appellate Division drew that line in Alampi v. Russo, 345 N.J. Super. 360 (App. Div. 2001) source , where an accountant who pled guilty to a federal misdemeanor -- and never attacked the plea by appeal or otherwise -- sued his former defense attorney for the advice that led to it. The court affirmed dismissal: a plaintiff cannot renounce in a civil courtroom a guilty plea he left fully intact in the criminal one. Notably, Alampi declined to demand complete exoneration as a universal prerequisite and refused to adopt an actual-innocence rule, but the practical holding was clear enough. If you have not obtained relief from the conviction, the malpractice suit is premature at best and barred at worst.

The New Jersey Supreme Court completed the framework in McKnight v. Office of the Public Defender, 197 N.J. 180 (2008) source . Garvin McKnight, a noncitizen who had lived in the United States since childhood, pled guilty to third-degree aggravated assault on his public defender's advice -- advice that never accounted for the plea making him deportable. The trial and appellate courts said his malpractice claim accrued back when immigration authorities first contacted him, which made his suit untimely. The Supreme Court reversed, adopting Judge Stern's dissent below: the statute of limitations on a criminal defendant's malpractice claim does not begin to run until the defendant receives relief in the form of exoneration. Exoneration in this sense is not a proclamation of innocence. It means relief from the judgment -- vacation of a guilty plea and dismissal of the charges, acquittal on retrial, conviction of a lesser offense after time served on the greater one, or any disposition more beneficial to the defendant than the original judgment.

Two consequences follow, and both matter to anyone reading this page. First, if your conviction still stands, your malpractice claim has not yet accrued -- the criminal remedy comes first, and filing the civil suit early accomplishes nothing. Second, once you obtain the exoneration, the clock starts, and it starts in earnest. The general six-year period of N.J.S.A. 2A:14-1 source governs claims against private counsel -- our page on the statute of limitations for suing your lawyer covers the accrual mechanics in detail -- but claims against public defenders run on a far shorter fuse, discussed below.

The PCR petition is where the malpractice case is actually built.

The route to exoneration for most people is a petition for post-conviction relief under R. 3:22 source , most often on the ground of ineffective assistance of counsel. The constitutional standard comes from Strickland v. Washington, 466 U.S. 668 (1984) source , which New Jersey adopted as its own state-constitutional standard in State v. Fritz, 105 N.J. 42 (1987) source : the defendant must show that counsel's performance was deficient, and that there is a reasonable probability the result would have been different but for the deficient performance.

Look at those two prongs next to the elements of a malpractice claim -- breach of the standard of care, and but-for causation of a worse outcome -- and the overlap is obvious. The PCR petition and the malpractice complaint are, at their core, the same argument made to two different courts for two different remedies. That overlap is why the criminal-side work has to be done with the civil case in mind:

  • A granted PCR is the strongest possible foundation -- a judicial finding, after an evidentiary hearing, that counsel's performance was constitutionally deficient and that it mattered. The finding does not automatically bind the civil court -- the attorney was not a party to the PCR proceeding -- but the PCR record hands the malpractice team its liability evidence largely pre-assembled.
  • The PCR record is discovery you cannot get anywhere else -- trial counsel typically testifies at the PCR hearing and must explain, under oath, why the witness was not interviewed or the motion was not filed. Strategy explanations that collapse on cross-examination in the PCR hearing rarely recover in the civil case.
  • PCR has its own deadline -- generally five years from the judgment of conviction under R. 3:22-12, relaxable only on a showing of excusable neglect and fundamental injustice. A missed PCR window can end the malpractice claim before it ever begins, because without the exoneration there is no accrual. If PCR counsel misses it, that failure can itself be malpractice -- a problem we address on our appellate malpractice page, since missed appeals and missed collateral deadlines travel together.

A point of candor about roles: we evaluate and litigate the malpractice case. The PCR petition itself is criminal work -- our criminal-defense and post-conviction-relief pages describe that practice -- and where a potential malpractice claim is visible while the PCR is still pending, coordinating the two matters early is worth far more than sequencing them by accident.

Why these cases are harder than civil malpractice -- and where they fail.

We owe you the unvarnished version. Criminal-defense malpractice claims carry every burden of an ordinary legal-malpractice case, plus several of their own.

The case-within-a-case runs through a criminal trial.

Like every New Jersey malpractice claim, this one requires the four elements set out in Saffer v. Willoughby, 143 N.J. 256 (1996) source -- relationship, negligence, causation, damages -- and the causation element requires proving the case within a case. Here the underlying case is a criminal prosecution, which means persuading a civil jury about what a criminal jury would have done: that the suppression motion would have been granted, that the alibi witness would have been believed, that the plea offer would have been accepted and honored. The State's evidence against you comes back into the room. Jurors who might readily accept that a personal-injury case was worth more than it settled for are slower to accept that an indicted defendant would have been acquitted.

The exoneration gate filters out most claims before they start.

The discipline of McKnight cuts both ways. It protects the diligent client's limitations period, and it bars everyone whose conviction was never undone. Most PCR petitions are denied. A denied PCR generally means no exoneration, which means no accrued malpractice claim -- no matter how badly the trial was handled. We decline a substantial share of criminal-malpractice inquiries for exactly this reason, and when we do, we say so directly rather than take a retainer for a case the law does not permit.

Public-defender cases run through the Tort Claims Act.

A large share of criminal-defense representation in New Jersey is performed by the Office of the Public Defender, and in Nieves v. Office of the Public Defender, 241 N.J. 567 (2020) source the Supreme Court held that the OPD is a public entity and its attorneys are public employees under the Tort Claims Act. The consequences are severe. A notice of claim must be served within 90 days of accrual under N.J.S.A. 59:8-8 source , with only a narrow one-year window for late notice on leave of court. Because accrual is tied to the exoneration, the 90 days generally start running when the PCR is granted or the charges are dismissed -- precisely the moment most people are celebrating rather than calendaring. And the Act's verbal threshold limits pain-and-suffering recovery: the plaintiff in Nieves had been cleared by DNA evidence and still lost his malpractice damages claim for failure to satisfy the Act. If your lawyer was a public defender, the consultation needs to happen before the PCR is decided, not after.

The Affidavit of Merit and the expert problem.

The malpractice complaint must be supported by an Affidavit of Merit under N.J.S.A. 2A:53A-27 source -- a sworn statement from an attorney in the same field that there is a reasonable probability the defendant's work fell outside acceptable professional standards, filed within 60 days of the answer, extendable to 120 for good cause. For criminal-defense malpractice that means finding an experienced criminal practitioner willing to review the trial record, the plea colloquy, and the PCR file and swear to the deficiency. Our Affidavit of Merit and expert witness pages cover the mechanics; the short version is that we do not file these cases until the expert groundwork is done.

Damages are real but constrained.

Fees paid to the negligent lawyer, the cost of curative criminal work, and earnings lost to a wrongful incarceration are the categories a jury can count. Loss-of-liberty and emotional-distress damages exist in principle and are fought over in practice -- and against public entities they must clear the Tort Claims Act threshold. There is no case-within-a-case verdict number to point at, the way there is when a lawyer loses a quantifiable injury claim. A separate statutory remedy, the Mistaken Imprisonment Act, N.J.S.A. 52:4C-1 to -7 source , allows compensation from the State for persons who can establish their innocence after a vacated conviction; where the facts support it, we evaluate that route alongside -- or instead of -- the malpractice claim, because the two have different elements and different defendants. The broader recovery framework is covered on our damages page.

What we do with a criminal-malpractice inquiry.

Because the viability of these cases turns on sequencing, the intake analysis is unusually structured. When you contact us about a criminal-defense malpractice matter, this is what actually happens:

  • Status of the conviction -- standing, on direct appeal, PCR pending, PCR granted, charges dismissed, retrial acquittal. This single fact determines whether a claim has accrued, is ripening, or is foreclosed.
  • Identity of the defense lawyer -- private counsel or public defender. If public, we calculate the Tort Claims Act notice deadline immediately, because it may be measured in days.
  • The negligence theory -- what the lawyer failed to do, and whether the PCR record already contains findings on it. Failure to investigate, defective plea advice, missed suppression issues, missed appeals, and conflicts of interest each require different proof.
  • The causation preview -- an honest read of whether a civil jury can be persuaded the criminal outcome would have been better. This is where most claims end, and we would rather end them in a conference room than in year two of litigation.
  • The file -- trial counsel's file belongs to you and must be surrendered on request under RPC 1.16(d) source . Our guide to getting your file explains how; in criminal cases the file request should also sweep in discovery received from the State.

Where the analysis supports it, we take these cases on the fee structures described on our fees page. Where it does not, the consultation ends with an explanation of why -- and, where a criminal remedy is still open, with a description of what would need to happen on the criminal side before the civil question can be asked again.

Scope note: We represent former criminal defendants harmed by their own attorneys. We do not defend attorneys against malpractice claims. Where a conflict prevents us from taking your case -- for example, a professional relationship with the attorney involved -- we will say so at intake and decline the matter.

Frequently asked questions

Can I sue my criminal defense lawyer for malpractice in New Jersey?

Yes, but only after some form of exoneration -- a vacated conviction, dismissed charges, acquittal on retrial, or another disposition better than the original judgment. While the conviction stands unimpeached, the malpractice claim is not yet viable.

In McKnight v. Office of the Public Defender, 197 N.J. 180 (2008)source, the New Jersey Supreme Court held that a criminal defendant's legal-malpractice claim against former defense counsel does not accrue until the defendant obtains exoneration-type relief. That relief can take several forms -- vacation of a guilty plea and dismissal of the charges, acquittal on retrial, conviction of a lesser offense, or any disposition more beneficial than the original judgment. Until then, the criminal judgment itself blocks the civil claim, because a valid conviction is treated as the legal cause of the harm.

Do I have to win post-conviction relief before I can sue?

As a practical matter, yes. The PCR petition under R. 3:22 -- or a direct appeal or plea-withdrawal motion -- is how most people obtain the exoneration McKnight requires. The criminal remedy comes first; the civil claim follows it.

New Jersey's exoneration rule makes the criminal-side remedy a prerequisite in practice. A petition for post-conviction relief under R. 3:22source asserting ineffective assistance of counsel is the most common route, but a successful direct appeal or a granted motion to withdraw a plea can also supply the exoneration. Before McKnightsource, the Appellate Division in Alampi v. Russo, 345 N.J. Super. 360 (App. Div. 2001)source barred a malpractice suit by a plaintiff who had never attacked his guilty plea at all -- the courts will not let a civil jury renounce a criminal judgment the defendant left standing.

Do I have to prove I was actually innocent?

No. New Jersey rejected an actual-innocence requirement. You must obtain relief from the conviction -- exoneration in the McKnight sense -- but you do not have to prove factual innocence to bring the malpractice claim.

Some states require a criminal-malpractice plaintiff to plead and prove actual innocence. New Jersey does not. The Appellate Division in McKnightsource reasoned that an actual-innocence rule would unfairly bar valid claims, and the Supreme Court's exoneration holding preserved that position: the gate is relief from the judgment, not proof of innocence. Your conduct in the underlying matter can still be relevant to the defense, but innocence is not an element you must establish.

What if my lawyer was a public defender?

Then the New Jersey Tort Claims Act applies. Under Nieves v. Office of the Public Defender, 241 N.J. 567 (2020)source, a notice of claim must be served within 90 days of accrual, and the Act's damages limitations apply.

The Office of the Public Defender is a public entity, and its attorneys are public employees for Tort Claims Act purposes. That means a malpractice claim against a public defender must comply with the Act's notice requirement -- a notice of claim served within 90 days of accrual under N.J.S.A. 59:8-8source, with a limited one-year late-notice window on leave of court. The Act's verbal threshold also restricts pain-and-suffering recovery. Because accrual under McKnight is tied to the exoneration, the 90-day clock generally starts when the exoneration-type relief is obtained -- which means the notice deadline can arrive fast on the heels of a PCR victory. This is one of the most commonly missed traps in criminal-malpractice cases.

What kinds of criminal-defense mistakes support a malpractice claim?

The recurring patterns: failure to investigate or interview witnesses, bad plea advice (including immigration consequences), missed suppression issues, missed appeal deadlines, and conflicts of interest -- each provable only after the conviction has been undone.

The fact patterns that reach us most often are failures to investigate an alibi or interview known witnesses; plea advice that misstated the sentencing exposure or omitted deportation consequences; suppression motions never filed despite an obvious search-and-seizure issue; notices of appeal never filed despite instructions to file them; and undisclosed conflicts, such as counsel simultaneously representing a co-defendant with an adverse interest. The same conduct usually supports the ineffective-assistance claim in the PCR proceeding first; the malpractice claim then converts the constitutional violation into a damages case.

What damages can I recover in a criminal-malpractice case?

The measurable losses the negligence caused: fees paid, income lost to incarceration or a wrongful conviction, and -- subject to significant limits, especially against public entities -- loss-of-liberty and emotional-distress damages.

Damages are the hardest part of these cases, and we will tell you that plainly at the consultation. Fees paid to the negligent attorney, the cost of the curative criminal work, and lost earnings during a wrongful incarceration are the most provable categories. Loss-of-liberty and emotional-distress damages are recognized in principle but heavily contested, and against a public defender they must clear the Tort Claims Act's verbal threshold -- the precise issue on which the plaintiff in Nievessource lost despite DNA evidence confirming he was not the perpetrator. Separately, a person whose conviction is vacated on grounds of innocence may have a claim against the State under the Mistaken Imprisonment Act, N.J.S.A. 52:4C-1 to -7, which is a distinct remedy we evaluate alongside the malpractice analysis.

Talk with a New Jersey attorney about your criminal-malpractice question.

The conversation is confidential, and nothing about it is communicated to your former attorney without your authorization. Call (800) 709-1131 or use our contact page. We will ask about the current status of the conviction, who the defense lawyer was, what the failure was, and what has already happened on appeal or in PCR. If your lawyer was a public defender and you have recently obtained relief, call promptly -- the Tort Claims Act notice period may already be running. We will tell you whether a claim appears to exist, what would have to be proved, and what it would take -- including where the honest answer is that the criminal remedy has to come first, or that no civil claim is available at all.
