What Does a Commercial Disputes Lawyer Do in Ediscovery?

Federal Rules of Civil Procedure Rule 26 and its state-law equivalents establish the duty to preserve ESI as soon as a party reasonably anticipates litigation. Courts have consistently held that failure to implement a litigation hold on relevant data, even if unintentional, can result in sanctions ranging from cost-shifting to case-dispositive adverse inferences. In practice, these disputes rarely map neatly onto a single rule, because courts weigh the sophistication of your IT systems, the burden of preservation, and the prejudice to the opposing party differently depending on the record. A commercial disputes lawyer helps your company document a reasonable preservation protocol early, before disputes arise over what should have been kept.

EDiscovery typically consumes 50 to 70 percent of discovery costs in commercial disputes, particularly when large volumes of unstructured data must be reviewed for privilege and relevance. Early involvement of counsel in designing a collection strategy, selecting appropriate technology-assisted review tools, and negotiating discovery protocols with opposing counsel can reduce waste and accelerate resolution. Courts in the Southern District of New York and state courts in New York County frequently address disputes over the adequacy of search methodologies and the cost allocation of review, and delays in establishing clear protocols early often result in expensive re-collection or re-review later in the case.

A commercial disputes lawyer works with your IT department to identify custodians (employees or contractors whose communications and files are likely to contain relevant information), define the scope of data sources (email servers, file shares, mobile devices, third-party platforms), and establish procedures to segregate and protect that data from routine deletion or alteration. The protocol must be documented in writing, communicated clearly to custodians, and monitored to ensure compliance. Courts expect this documentation, and its absence or vagueness often leads to sanctions or adverse inferences that harm your case.

Many companies struggle with the tension between litigation holds and normal IT practices such as data migration, system upgrades, or cloud consolidation. Your lawyer advises on how to navigate these conflicts without waiving preservation duties or incurring unnecessary costs. In some cases, counsel may negotiate with opposing parties for a phased collection schedule or agree to cost-sharing for specialized forensic imaging of legacy systems. The key is communicating these decisions to the court and opposing counsel in advance, rather than discovering gaps or lost data months later during depositions or document production.

Predictive coding, machine learning, and other analytics tools now allow lawyers to prioritize high-value documents, reduce redundancy, and lower the per-document review cost. Your commercial disputes lawyer evaluates which tools are appropriate for your case, negotiates their use with opposing counsel, and ensures that any technology-assisted review is transparent and defensible. Courts in New York have increasingly accepted these methods when the underlying methodology is sound and disclosed, and many discovery disputes now focus on whether the search strategy and technology deployment were reasonable rather than on the volume of documents reviewed.

A critical responsibility during review is identifying privileged communications (attorney-client privileged or work product) and withholding them from production while maintaining a privilege log that describes the withheld items. Inadvertent disclosure of privileged material can waive the privilege, and New York courts apply strict standards to claw-back agreements and the procedures for remediating disclosure. Your lawyer ensures that your review protocol includes clear training on privilege recognition and a secondary review layer to catch missed issues before production.

Before formal discovery begins, your lawyer negotiates a discovery plan with opposing counsel that addresses search terms, custodians, data sources, and cost allocation. This negotiation is governed by Rule 26(b)(1), which limits discovery to information that is proportional to the needs of the case, considering the importance of the issues, the amount in controversy, and the parties' resources. A commercial disputes lawyer frames your company's eDiscovery requests and objections with proportionality in mind, reducing the risk that a court will sanction your discovery conduct or impose cost-shifting. These negotiations also often involve issues related to commercial general liability insurance coverage, where third-party insurers may have obligations to fund defense costs, including eDiscovery expenses.

When negotiation fails, disputes over the adequacy of searches, the scope of preservation, or cost allocation may be brought before a judge in a motion practice. Your lawyer prepares detailed declarations from IT experts, custodians, and other witnesses to demonstrate that your company's eDiscovery efforts were reasonable and compliant with court orders. The goal is to avoid sanctions or adverse inferences that would undermine your substantive claims or defenses. In rare cases involving serious misconduct, such as intentional destruction of evidence or spoliation, courts may refer matters to law enforcement or impose case-dispositive sanctions, and counsel must be prepared to defend your company's conduct or, if necessary, address the ethical and legal implications of any lapses.
