Why Should You Prioritize Legal Due Diligence before Any Investment?

Early conversations between counsel and the client must establish what information is accessible, what questions the target will answer, and what timing constraints exist. In practice, these conversations reveal whether the target is cooperative or defensive, which itself signals risk. A target that resists document access or delays responses often indicates underlying problems. The due diligence scope should be documented in a data request list or information memorandum so expectations remain clear, and disputes over completeness do not delay closing.

Counsel must establish a protocol for organizing, storing, and reviewing due diligence materials. This includes maintaining a privilege log if attorney work product is created, preserving emails and communications for potential litigation, and ensuring compliance with data privacy regulations if the target operates in regulated industries or holds personal information. Many transactions fail to close cleanly because document review reveals inconsistencies between representations and actual records. Creating a centralized repository and documenting the review process protects against later claims that counsel failed to discover material facts.

In New York State, many regulated industries require active licenses from state departments or local agencies. For example, healthcare providers must maintain Department of Health certifications, financial services firms must comply with Department of Financial Services requirements, and environmental contractors must hold DEC permits. Counsel should verify that all required licenses are current, held in the correct legal entity, and not subject to restrictions or conditions that would impair operations post-closing. New York courts have enforced strict liability for operating without required licenses, meaning a buyer may inherit both the violation and the penalties if the license status is not confirmed before closing.

Counsel must search for pending or settled enforcement actions, fines, consent orders, and regulatory inquiries. Many targets do not voluntarily disclose minor violations or closed investigations unless specifically asked. A search of state and federal regulatory databases, combined with targeted questions in the due diligence questionnaire, often uncovers issues that management did not mention. These discoveries allow counsel to assess the severity of risk, negotiate indemnification provisions, and determine whether regulatory remediation is required before closing.

Counsel must obtain a complete list of pending, threatened, and settled litigation involving the target. This includes lawsuits filed against the company, claims by employees or customers, regulatory disputes, and arbitrations. Many targets underreport litigation risk or downplay the severity of pending cases. A review of court dockets, demand letters, and settlement agreements reveals the true exposure. In one representative case, a buyer discovered during closing that the target faced a class action employment lawsuit alleging wage violations; the target had not disclosed the claim, and the buyer ultimately inherited the liability and defense costs.

Tax due diligence examines whether the target has filed all required tax returns, paid assessed taxes, and complies with transfer pricing and international tax rules. Counsel should request IRS transcripts, state tax clearance certificates, and documentation of any tax audits or disputes. Tax liabilities often survive closing and attach to the buyer, so identifying exposure before signing allows counsel to negotiate escrow holdbacks, indemnification, or purchase price adjustment. Counsel should also review whether the target qualifies for any tax benefits or carries forward losses that may be limited under change-of-control rules.

Many material contracts restrict assignment or require counterparty consent upon a change of control. Counsel must identify which contracts contain these provisions, assess the likelihood that consent will be granted, and determine the cost or conditions of obtaining consent. Some contracts allow termination without consent if control changes, creating revenue risk. A target that depends on one or two major customer contracts with change-of-control provisions faces significant deal risk if those customers may terminate post-closing. Counsel should obtain preliminary consents or commitment letters before closing whenever possible.

Intellectual property due diligence examines ownership of patents, trademarks, copyrights, and trade secrets; licenses from third parties; and infringement risks. Counsel must verify that the target owns all intellectual property it claims to own, that no third-party licenses are required for core operations, and that the target does not infringe third-party rights. Intellectual property ownership disputes and infringement claims can render a business worthless post-closing. Counsel should search the USPTO database, review intellectual property assignment agreements, and interview technical staff about the origin of key technologies.
