Under New York law, an attorney’s failure to commence a lawsuit may constitute legal malpractice when the attorney’s negligence causes a client to lose a viable legal claim or suffer other actual financial damages.

Yes, you may be able to sue an attorney for failing to file your lawsuit in New York. However, you generally must prove that the attorney acted negligently, that the negligence caused your loss, and that you suffered actual damages.

Not every failure to file a lawsuit amounts to malpractice. The circumstances of the attorney-client relationship, the applicable deadlines, and the merits of the original case all matter.

Does an Attorney Have a Legal Obligation to File Your Lawsuit?

An attorney’s responsibilities depend on the scope of the representation and the services the attorney agreed to provide.

If an attorney accepts responsibility for pursuing a lawsuit, the attorney generally must exercise the ordinary reasonable skill and knowledge commonly possessed by members of the legal profession.

That includes identifying applicable filing deadlines, evaluating the legal claim, and taking reasonable steps to protect the client’s interests within the agreed scope of representation.

However, hiring an attorney for an initial consultation does not necessarily mean the attorney agreed to file a lawsuit. A lawyer may decline representation or accept a limited engagement.

Determining whether the attorney was responsible for commencing the case often requires reviewing the retainer agreement, correspondence, and communications between the attorney and client.

When Does Failing to File a Lawsuit Become Legal Malpractice in New York?

An attorney’s failure to file a lawsuit may constitute malpractice when it falls below the applicable professional standard of care and causes a client an identifiable loss.

Examples of potentially negligent conduct include:

• Agreeing to commence a lawsuit but failing to do so before the statute of limitations expires.
• Overlooking a filing deadline that applies to the client’s claim.
• Failing to take necessary steps to commence an action after accepting responsibility for doing so.
• Neglecting a client’s case until the opportunity to pursue the claim is lost.
• Failing to communicate a decision not to pursue the case when that omission contributes to a preventable loss.
• Failing to satisfy applicable procedural requirements necessary to preserve the client’s claim.

Each situation must be evaluated individually. An attorney’s decision not to file an unsupported or legally defective claim is not automatically malpractice.

What Must You Prove to Sue an Attorney for Not Filing Your Case?

New York courts generally require a legal malpractice plaintiff to establish three essential elements.

1. The Attorney Was Negligent

You must show that the attorney failed to exercise the ordinary reasonable skill and knowledge expected of a member of the legal profession.

For example, allowing an actionable claim to expire after agreeing to pursue it may support an allegation of negligence.

2. The Attorney’s Conduct Caused Your Loss

You generally must establish that, but for the attorney’s negligence, you would have obtained a more favorable result in the original legal matter.

If the underlying claim would have failed regardless of the attorney’s conduct, proving malpractice may be difficult.

3. You Suffered Actual Damages

The alleged negligence must have caused actual, ascertainable damages.

These damages may include the value of a legal claim that could have produced compensation but was lost because the attorney failed to act.

New York courts have addressed these requirements in decisions including Rudolf v. Shayne, Dachs, Stanisci, Corker & Sauer, 8 N.Y.3d 438 (2007).

What Happens If Your Attorney Never Filed Your Lawsuit?

The consequences depend on whether the filing deadline has expired and whether the underlying legal claim remains viable.

If the applicable statute of limitations has not expired, another attorney may still be able to commence the original lawsuit.

If the deadline has passed, the potential defendant may assert a statute of limitations defense. Depending on the facts, this could result in dismissal of the claim.

However, expiration of a general filing deadline does not necessarily resolve every case. Certain tolling rules, statutory exceptions, or procedural provisions may affect whether an action remains timely.

Because those issues can be complex, obtaining an independent review of the original claim is important before assuming that all legal options have been lost.

What If Your Attorney Told You the Lawsuit Was Filed but It Wasn’t?

Discovering that your attorney represented that a lawsuit had been filed when no action was commenced can raise serious concerns.

Such circumstances may involve questions about professional negligence, communication, and the accuracy of the information provided to the client.

Important evidence may include emails, letters, text messages, copies of purported court filings, and court docket records.

Whether the attorney’s conduct supports a legal malpractice claim still depends on causation and actual damages. Separate professional disciplinary issues may also arise.

A client who suspects that an attorney misrepresented the status of a lawsuit should consider promptly obtaining the court records and seeking independent legal advice.

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 action generally must be commenced within three years after the claim accrues.

The limitations period generally runs from the actionable malpractice, rather than from the date the client discovers the attorney’s mistake.

When the alleged negligence involves failing to file an action, determining the accrual date requires a careful review of the attorney’s conduct and the relevant procedural deadlines.

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

Can Continuous Representation Extend the Deadline to Sue Your Lawyer?

New York recognizes the continuous representation doctrine, which may toll the legal malpractice statute of limitations while an attorney continues representing a client in the same specific matter involving the alleged malpractice.

The doctrine does not apply merely because an attorney and client maintain a general professional relationship.

Courts consider whether there was continuing representation concerning the particular matter and a mutual understanding of the need for further legal services.

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

Clients should not assume that occasional contact with a former attorney automatically extends the deadline for bringing a malpractice lawsuit.

What Is the Case Within a Case Requirement?

When an attorney’s failure to file a lawsuit causes the original claim to be lost, the former client generally must demonstrate that the underlying lawsuit would have produced a more favorable outcome if it had been properly pursued.

This is commonly called proving the “case within a case.”

For example, suppose an attorney agreed to file a personal injury lawsuit but failed to commence the action before the deadline expired.

In a later malpractice lawsuit, the client may need to establish that the original defendant was legally responsible for the injury and that the client would have recovered damages.

The strength of the original claim therefore matters just as much as the attorney’s failure to file it.

What Evidence Can Help Prove an Attorney Failed to File Your Lawsuit?

Evidence documenting the attorney-client relationship and the status of the original claim may help establish whether malpractice occurred.

Useful records include:

• Retainer agreements: Documents identifying the services the attorney agreed to provide.
• Emails and text messages: Communications discussing the lawsuit and its expected filing date.
• Court records: Docket information showing whether an action was commenced.
• Letters from the attorney: Statements about the case’s progress or filing status.
• Underlying case evidence: Records supporting the original legal claim.
• Financial documentation: Materials demonstrating the losses allegedly caused by the failure to file.

Preserving the complete case file may also help determine whether another attorney can still pursue the original matter.

Can You Recover Money If Your Attorney Failed to File Your Lawsuit?

Potentially. New York legal malpractice law generally permits recovery of actual damages proximately caused by attorney negligence.

If the failure to commence a lawsuit caused a client to lose an otherwise viable claim, the value of that lost claim may form part of the damages analysis.

However, the amount sought in the original lawsuit does not automatically become the amount recoverable in a malpractice action.

The client must establish what a favorable result in the underlying matter would have been worth and show that the attorney’s negligence caused the loss.

Speculative damages generally are not sufficient to support a legal malpractice recovery.

What Should You Do If Your Attorney Failed to File Your Lawsuit?

If you believe an attorney failed to commence a lawsuit that the attorney agreed to pursue, consider the following steps:

1. Request your case file. Obtain copies of your retainer agreement, correspondence, and relevant documents.
2. Verify the filing status. Determine whether the lawsuit was actually commenced and whether any court records exist.
3. Identify applicable deadlines. Establish when the original claim arose and whether the filing period has expired.
4. Preserve communications. Save records showing what the attorney agreed to do and what was communicated about the case.
5. Consult an independent New York attorney. Obtain an assessment of the underlying lawsuit and any potential malpractice claim.

Acting promptly matters because the original lawsuit may still be viable, and a separate limitations period may apply to any legal malpractice action.

Frequently Asked Questions About Attorneys Failing to File Lawsuits in New York

Can I sue my lawyer if they promised to file my lawsuit but never did?

You may have a claim if the attorney accepted responsibility for filing the lawsuit, negligently failed to do so, and caused you actual damages.

What if the statute of limitations has not expired yet?

If the underlying claim remains timely, another attorney may be able to commence the lawsuit. Whether a separate malpractice claim exists depends on whether the prior attorney’s conduct caused a compensable loss.

Is failing to file a lawsuit automatically malpractice?

No. The attorney’s obligations, the reasons for not filing, the merits of the underlying claim, and any resulting damages must all be considered.

Can I sue if my attorney lied about filing the lawsuit?

Possibly. Misrepresentations about a lawsuit’s status may raise serious concerns, but a civil malpractice claim generally still requires proof of negligence, causation, and actual damages. Other legal or disciplinary issues may also be relevant.

How much time do I have to sue my attorney in New York?

Legal malpractice lawsuits generally have a three-year statute of limitations under CPLR § 214(6), subject to applicable tolling doctrines and other legal rules.
