Unfortunately, attorneys can make mistakes. Some errors may cause inconvenience or frustration, while others can result in dismissed lawsuits, lost financial opportunities, or other serious consequences.

Under New York law, an attorney may be held responsible for legal malpractice when professional negligence causes a client actual, ascertainable damages.

Common signs of legal malpractice in New York include missed filing deadlines, failure to investigate a case, mishandling important evidence, failure to respond to court proceedings, and other professional errors that cause a client to lose a viable legal claim or suffer financial harm.

However, an unfavorable outcome or disagreement with your attorney does not automatically establish malpractice. Understanding the difference between negligence and ordinary dissatisfaction is an important first step.

What Is Considered Legal Malpractice in New York?

Legal malpractice generally occurs when an attorney fails to exercise the ordinary reasonable skill and knowledge commonly possessed by a member of the legal profession, and that failure causes a client actual damages.

New York courts generally require a plaintiff to establish that the attorney was negligent, that the negligence proximately caused the client’s loss, and that the client suffered actual, ascertainable damages.

The New York Court of Appeals addressed these requirements in Rudolf v. Shayne, Dachs, Stanisci, Corker & Sauer, 8 N.Y.3d 438 (2007).

For example, an attorney who misses a critical filing deadline may have acted negligently. But to establish malpractice, the client generally must also demonstrate that the missed deadline caused a compensable loss.

What Are the Most Common Signs of Legal Malpractice in New York?

Although every attorney-client relationship is different, certain circumstances may indicate that an attorney failed to meet the applicable professional standard of care.

1. Your Attorney Missed an Important Filing Deadline

Missing the statute of limitations is one of the most serious potential attorney errors.

If an attorney fails to commence a lawsuit before the applicable deadline expires, the client may lose the ability to pursue an otherwise valid legal claim.

Other missed deadlines may involve notices of appeal, court-ordered submissions, or procedural requirements necessary to preserve a client’s rights.

Whether the mistake constitutes malpractice depends on the circumstances and the harm it caused.

2. Your Lawyer Failed to File the Lawsuit You Hired Them to Pursue

An attorney who accepts responsibility for filing a lawsuit generally must take reasonable steps to protect the client’s interests within the agreed scope of representation.

If the attorney fails to commence the action and the client’s legal rights are lost, the failure may support a malpractice claim.

The retainer agreement and communications between the attorney and client may help establish the services the attorney agreed to provide.

3. Your Attorney Failed to Investigate Important Facts

Attorneys may need to investigate relevant facts, obtain documents, interview witnesses, or pursue other evidence to prepare a client’s case.

For example, an attorney handling an injury claim may need to examine available accident records, medical evidence, and information about potentially responsible parties.

A failure to conduct a reasonably necessary investigation may constitute negligence if it causes a client to lose a viable claim or suffer another identifiable loss.

4. Your Lawyer Failed to Respond to Court Motions or Orders

Litigation often requires attorneys to respond to motions, comply with court orders, and meet procedural deadlines.

Failing to respond to a significant motion may result in an adverse ruling or other consequences.

If the attorney’s failure falls below the applicable standard of care and causes actual damages, it may support a legal malpractice lawsuit.

5. Your Attorney Lost or Failed to Preserve Important Evidence

Evidence can play a critical role in establishing liability and damages.

Depending on the case, important materials may include contracts, financial records, photographs, medical documents, witness statements, and electronic communications.

If an attorney negligently mishandles evidence and that mistake causes a client to lose a legal claim or suffer financial harm, the circumstances may warrant a malpractice review.

6. Your Lawyer Settled Your Case Without Authorization

Clients generally control whether to accept a settlement offer, subject to the terms and circumstances of the representation.

An attorney who enters into a settlement without appropriate authority may raise serious questions about the scope of the attorney’s authority and compliance with professional obligations.

Whether the conduct supports a legal malpractice claim depends on the resulting harm and other relevant legal requirements.

7. Your Attorney Failed to Identify a Necessary Defendant

Some lawsuits involve multiple potentially responsible parties.

An attorney’s failure to identify and timely pursue a claim against an appropriate defendant may prevent the client from recovering compensation that otherwise would have been available.

For example, a personal injury case may involve questions about the responsibility of a property owner, contractor, employer, or another party.

If an attorney’s negligent failure to identify a responsible party causes a compensable loss, legal malpractice may be an issue.

8. Your Attorney Gave Incorrect Legal Advice

Clients frequently rely on attorneys to explain legal rights, obligations, and available options.

Incorrect advice may constitute malpractice when it falls below the applicable professional standard of care and causes actual financial harm.

However, attorneys are not automatically liable whenever a court rejects a legal argument or a reasonable professional judgment proves unsuccessful.

9. Your Attorney Failed to Protect Your Right to Appeal

Appeals are governed by specific procedural requirements and deadlines.

If an attorney was responsible for preserving appellate rights but negligently failed to take the required steps, the client may lose the opportunity to seek appellate review.

Establishing malpractice generally requires showing that the error caused a more favorable legal outcome to be lost.

10. Your Attorney Stopped Communicating or Abandoned Your Case

Attorneys have professional obligations concerning communication and the handling of client matters.

Repeatedly unanswered messages, unexplained inactivity, or an attorney’s sudden disappearance may be warning signs that require further investigation.

However, poor communication alone does not automatically establish legal malpractice.

A civil malpractice claim generally requires proof that the attorney’s conduct caused actual damages. Communication failures may also raise separate professional disciplinary concerns.

What Is the Difference Between a Bad Case Outcome and Legal Malpractice?

Losing a lawsuit does not necessarily mean your attorney committed malpractice.

Legal proceedings involve uncertainty. Witnesses may provide conflicting testimony, evidence may be disputed, and courts may interpret the law differently than anticipated.

An attorney may exercise reasonable professional judgment and still obtain an unfavorable result.

Legal malpractice generally requires more than dissatisfaction with the outcome. The client must establish a departure from the applicable professional standard of care, causation, and actual damages.

For example, losing a case after reasonable preparation and litigation is different from losing a viable claim because an attorney negligently missed a mandatory filing deadline.

How Do You Prove Legal Malpractice in New York?

To establish a legal malpractice claim in New York, a plaintiff generally must prove three elements.

Attorney Negligence

The attorney must have failed to exercise the ordinary reasonable skill and knowledge commonly possessed by a member of the legal profession.

Causation

The plaintiff must generally demonstrate that, but for the attorney’s negligence, the client would have obtained a more favorable result in the underlying matter.

Actual Damages

The client must establish actual, ascertainable damages caused by the attorney’s negligence.

These requirements help distinguish compensable professional negligence from mistakes that did not affect the client’s legal or financial position.

What Is the Case Within a Case Requirement?

Many New York legal malpractice claims require the former client to demonstrate that the original legal matter would have produced a more favorable outcome if the attorney had acted competently.

This is commonly referred to as the “case within a case.”

For example, suppose an attorney negligently failed to file a personal injury lawsuit before the statute of limitations expired.

The former client may need to establish that the underlying defendant was legally responsible for the injury and that the client would have recovered damages if the lawsuit had been timely commenced.

The original case’s evidence and potential defenses therefore remain important even after the alleged attorney negligence occurs.

How Long Do You Have to File a Legal Malpractice Lawsuit in New York?

Under New York Civil Practice Law and Rules (CPLR) § 214(6), a legal malpractice lawsuit generally must be commenced within three years after the claim accrues.

The limitations period generally begins when the actionable malpractice occurs, rather than when the client discovers the mistake.

This distinction matters because a client may learn about an attorney’s error after substantial time has already passed.

Some circumstances may affect the limitations period, including the continuous representation doctrine.

What Is the Continuous Representation Doctrine in New York?

New York’s continuous representation doctrine may toll the statute of limitations when an attorney continues representing a client in the same specific matter involving the alleged malpractice.

The doctrine generally requires continuing representation concerning the particular legal matter, rather than merely an ongoing professional relationship.

The New York Court of Appeals addressed the doctrine in Shumsky v. Eisenstein, 96 N.Y.2d 164 (2001), and McCoy v. Feinman, 99 N.Y.2d 295 (2002).

Whether the doctrine applies depends on the facts of the representation and the parties’ understanding of the need for further legal services.

What Evidence Should You Gather If You Suspect Legal Malpractice?

If you believe your attorney may have committed legal malpractice, preserving relevant documents can help another attorney evaluate your situation.

Useful materials may include:

• Retainer agreements: Documents identifying the attorney’s responsibilities and scope of representation.
• Emails and text messages: Communications about deadlines, legal advice, and case progress.
• Court records: Pleadings, motions, orders, and dismissal notices.
• Settlement communications: Written offers and correspondence concerning settlement decisions.
• Original case evidence: Documents supporting the underlying legal claim.
• Financial records: Evidence of losses allegedly resulting from the attorney’s conduct.

A timeline showing when the attorney was retained, when the alleged mistake occurred, and when the representation ended may also be helpful.

What Compensation May Be Available in a New York Legal Malpractice Case?

A successful legal malpractice lawsuit may allow a client to recover actual damages proximately caused by the attorney’s negligence.

Depending on the circumstances, damages may include the value of a lost legal claim or other identifiable financial losses.

However, the amount requested in the original lawsuit does not automatically determine the amount recoverable in a malpractice action.

Damages must be supported by legally sufficient evidence rather than speculation.

Emotional distress and punitive damages generally are not recoverable in ordinary legal malpractice actions based solely on professional negligence.

What Should You Do If You Believe Your Attorney Committed Legal Malpractice?

If you suspect that your attorney’s conduct caused you financial harm, consider taking the following steps:

1. Request your case file. Obtain available documents and communications relating to the representation.
2. Identify the alleged mistake. Determine what the attorney did or failed to do and when it occurred.
3. Preserve supporting evidence. Save court documents, emails, letters, and records relating to the underlying matter.
4. Review applicable deadlines. The limitations period for a malpractice lawsuit may already be running.
5. Consult an independent New York legal malpractice attorney. A separate attorney can assess whether the conduct caused a legally compensable loss.

Prompt legal review may be particularly important if the original lawsuit remains pending or additional steps could still protect your rights.

Can I sue my attorney simply because I lost my case?

No. An unfavorable outcome alone does not establish malpractice. You generally must prove attorney negligence, causation, and actual damages.

Poor communication may raise professional concerns, but it does not automatically support a civil malpractice claim. The client generally must establish that the attorney’s conduct caused actual damages.

Can I sue my attorney for missing a deadline?
