Lost wages represent a crucial component of personal injury compensation, yet proving them can be surprisingly complex. New York courts maintain strict standards for establishing past earnings, requiring plaintiffs to provide concrete documentation rather than relying solely on testimony. This standard becomes particularly challenging for healthcare professionals and self-employed individuals who may be reluctant to disclose detailed financial records during litigation.

A recent First Department decision illustrates these evidentiary hurdles and highlights the ongoing tension between plaintiffs’ privacy concerns and the legal requirement to substantiate damages claims with verifiable proof.

Case Background

In Martinez v Metropolitan Transportation Authority, the plaintiff sought damages including compensation for lost earnings resulting from injuries sustained in an accident. The plaintiff testified about her income and the wages she lost due to her inability to work during recovery. However, the plaintiff did not produce tax returns, W-2 forms, or other financial documentation corroborating her testimony about past earnings.

The defendant moved for summary judgment on various aspects of the plaintiff’s damages claim, including the lost wages component. The defendant argued that the plaintiff failed to establish past lost earnings with the reasonable certainty required under New York law. The First Department reviewed whether plaintiff testimony alone, absent documentary corroboration, suffices to establish lost wage damages.

The court’s analysis focused on the evidentiary requirements for proving past lost earnings and whether oral testimony without supporting documentation creates a triable issue of fact on damages.

Jason Tenenbaum’s Analysis:

Martinez v Metropolitan Transp. Auth., 2018 NY Slip Op 02028 (1st Dept. 2008)

“Plaintiff failed to establish her past lost earnings with reasonable certainty since her testimony was unsubstantiated by tax returns, W-2 forms, or other documentation (Orellano v 29 E. 37th St. Realty Corp., 4 AD3d 247 , lv denied 4 NY3d 702 ; cf. Kane v Coundorous, 11 AD3d 304, 305 ).”

My sources certain insurance companies refuse to pay plaintiff healthcare practitioners who come in for EUOs. Question always becomes how do you prove lost wages? Healthcare professionals are loathe to give up their tax records and bank statements. Those “marketing charges”, “maintenance charges”, “computer upkeep charges” – well are a Pandoras box that makes payroll for SIU defense firms

What “other documentation” can prove lost wages?

Key Takeaway

The Martinez decision reinforces New York’s demanding documentation requirements for lost wage claims. Healthcare professionals face a particular dilemma: courts require substantial financial proof, but providing tax returns and bank statements may expose business practices to intense scrutiny from insurance defense teams, potentially creating more legal complications than the original injury claim.

The Martinez decision reflects New York’s consistent application of the “reasonable certainty” standard for proving damages. While plaintiffs can testify about their injuries and pain, courts demand objective verification for economic losses like lost wages. This distinction stems from the relative ease with which parties could fabricate or exaggerate income claims absent documentation requirements.

The court’s use of “or” when listing acceptable documentation—tax returns, W-2 forms, “or other documentation”—raises the question Jason poses: what alternatives exist to traditional tax documents? While the court does not specify, potential alternatives might include business records showing actual income received, accountant certifications, or pay stubs from employers. However, any alternative must provide the same level of objective verification that tax returns offer.

Jason’s observation about healthcare professionals facing EUO demands highlights a strategic dilemma unique to medical providers injured in accidents. These plaintiffs must prove lost earnings to recover damages, but providing detailed financial records exposes them to investigation of their business practices. Insurance carriers’ Special Investigation Units actively scrutinize medical provider financial records for evidence of billing irregularities, marketing arrangements, or other practices that might support fraud allegations.

Practical Implications

Plaintiff attorneys representing healthcare professionals or self-employed individuals must address lost wage documentation early in case development. Counsel should obtain tax returns, bank records, and business financial statements during initial case intake, analyzing them for any problematic entries before deciding whether to pursue lost wage claims. If financial records contain questionable deductions or unusual income sources, attorneys must weigh whether the lost wage damages justify the litigation risk.

For plaintiffs concerned about privacy, partial redaction of irrelevant financial information may provide a compromise, though courts generally permit broad discovery into income sources when plaintiffs place earnings in controversy. Alternative documentation strategies, such as certified accountant affidavits synthesizing financial data without producing raw records, may satisfy some courts but risk objections that such summaries lack the reliability of source documents like tax returns.

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
