Due diligence in mergers and acquisitions (M&A) is not just about confirming financials and operations-it is also a critical process for identifying potential legal landmines. One of the most significant red flags that can arise is the discovery of pending or potential litigation. Failing to properly address litigation risks during due diligence can result in unexpected liability, valuation disputes, and even deal collapse. In this article, we'll explore the types of litigation risks commonly uncovered, why they matter, and how buyers and sellers can address them.

Why Litigation Risk Assessment Is Critical in M&A
When a business is involved in litigation-or has a history of disputes-those legal matters can follow the business even after a transaction is closed. This is especially true in asset purchases, stock purchases, and mergers. Litigation risk can:
-
Diminish the value of the business
-
Delay or derail closing
-
Introduce long-term legal exposure
-
Affect third-party relationships (vendors, clients, regulators)
That's why comprehensive legal due diligence-especially litigation review-is a non-negotiable element of a well-structured deal.
Common Types of Litigation Risks Found in Due Diligence
During due diligence, attorneys and buyers should look for both actual litigation (pending lawsuits) and potential litigation (threatened claims or unresolved disputes). These often include:
1. Pending Lawsuits
-
Civil claims from customers, employees, or vendors
-
Breach of contract claims
-
Intellectual property disputes
-
Shareholder or partnership lawsuits
2. Regulatory Actions and Government Investigations
-
Environmental violations
-
Employment law issues
-
Noncompliance with data privacy regulations
-
SEC or FTC inquiries
3. Employee and Labor Disputes
-
Discrimination or harassment claims
-
Wage and hour violations
-
Union grievances or NLRB investigations
4. Product Liability and Consumer Protection Claims
-
Claims related to product defects or misrepresentations
-
Class action lawsuits
-
Consumer fraud claims
5. Tax Disputes and IRS Audits
-
Unpaid taxes or ongoing audits
-
Disputes over valuation, deductions, or reporting
Each of these areas may carry not only direct liability but also reputational damage and long-term consequences.
Red Flags to Watch for in Litigation Disclosures
Not every disclosed lawsuit or claim is a deal-breaker. But some red flags should prompt a closer look-or even reconsideration of the deal structure:
-
High-value claims with potential for large settlements or judgments
-
Repetitive litigation, such as multiple similar claims over time
-
Lack of insurance coverage for legal liabilities
-
Failure to disclose known disputes or threats of litigation
-
Investigations by federal agencies, such as the Department of Justice or EPA
-
Outstanding judgments or liens that affect ownership or operations
Sellers may try to downplay ongoing litigation. Buyers should conduct independent investigations and confirm disclosures with third-party sources when possible.
How to Investigate Litigation Risk Effectively
A thorough legal due diligence process will go beyond what the seller provides voluntarily. Steps to conduct effective litigation risk assessments include:
-
Request All Litigation and Legal Proceedings Documentation
-
Open cases, resolved cases, and settlements
-
Correspondence with regulatory agencies
-
Legal invoices and counsel communications
-
-
Search Public Records
-
Civil court filings
-
Federal and state litigation databases
-
UCC filings and liens
-
-
Interview Key Personnel
-
General counsel, legal advisors, HR leaders, compliance officers
-
-
Review Insurance Coverage
-
General liability, E&O, D&O, product liability, and cyber liability policies
-
Exclusions and coverage caps
-
-
Assess Legal Reserve Accounting
-
Whether the business has set aside adequate reserves for claims
-
Negotiating Protections for Litigation Risk
If litigation risks are discovered, the deal can still proceed-if properly structured. Legal counsel should help buyers:
-
Negotiate indemnity clauses: Require the seller to cover specific types of claims.
-
Use purchase price adjustments: Reduce the purchase price to account for legal exposure.
-
Establish escrow accounts: Hold a portion of the purchase funds to cover future claims.
-
Obtain representations and warranties: Secure statements from the seller regarding the status of legal disputes.
For sellers, proactively addressing litigation risk builds trust with buyers and helps avoid delays or value reduction.
Litigation Risk in Asset vs. Stock Transactions
How a deal is structured significantly affects how litigation risk transfers. In stock purchases and mergers, buyers generally inherit all liabilities-disclosed and undisclosed. In asset purchases, buyers can often structure the deal to exclude certain liabilities.
However, even in asset sales, some liabilities-such as successor liability for product defects, environmental violations, or unpaid employment claims-may still follow the buyer depending on jurisdiction or federal statutes. Therefore, relying solely on transaction type is not enough to mitigate litigation exposure.
Legal guidance is essential in drafting transaction documents to clarify responsibility and protect the buyer's interests.
The Role of Disclosure Schedules in Managing Legal Risk
In M&A agreements, disclosure schedules are attachments that list exceptions to the seller's representations and warranties. These are critical tools for identifying and documenting litigation issues.
For example, a seller might represent that "there is no litigation pending or threatened against the company," but then disclose an exception such as "except for the matter filed in XYZ County on [Date] alleging breach of contract."
Buyers should:
-
Review disclosures carefully and ensure they are complete and up to date
-
Cross-reference court dockets and third-party reports to verify accuracy
-
Push for updates prior to closing to capture newly filed actions
Incomplete or vague disclosures can be grounds for post-closing disputes or litigation between buyer and seller.
Environmental and Industry-Specific Litigation Risks
Certain industries face unique legal exposures that must be evaluated during due diligence:
-
Healthcare and Life Sciences: HIPAA violations, Medicare fraud, FDA enforcement
-
Technology and SaaS: IP infringement, software licensing disputes, cybersecurity incidents
-
Manufacturing: OSHA compliance, toxic torts, product recalls
-
Financial Services: SEC and FINRA investigations, investor lawsuits
-
Real Estate and Construction: Zoning violations, construction defect claims, contract disputes
Understanding the regulatory landscape and typical claims for the target's industry helps predict where liabilities may lie.
Post-Closing Risk: What Happens If Litigation Arises After the Deal?
Even after a transaction closes, litigation may arise based on pre-closing activities. This is why indemnification provisions and survival periods matter.
Key elements to address include:
-
Who pays for the defense and settlement?
-
How long do representations and warranties survive post-closing?
-
Is there a cap or deductible for indemnification?
-
Does the buyer need to notify the seller within a specific period?
Buyers can protect themselves through rep & warranty insurance, escrow accounts, and strong indemnity provisions tailored to the specific litigation risks identified.
Tips for Sellers to Prepare for Litigation Due Diligence
Sellers anticipating a transaction can take proactive steps to reduce friction during legal due diligence:
-
Resolve or settle open claims before going to market
-
Disclose early and transparently to build buyer confidence
-
Work with legal counsel to prepare accurate disclosure schedules
-
Organize legal files and insurance records
-
Update corporate records and compliance certifications
Clean legal records and proactive disclosures can preserve deal value and prevent delays.
When Litigation Risk Becomes a Deal Breaker
While many litigation risks can be managed, some scenarios raise serious concerns:
-
Criminal investigations or indictments
-
Mass tort or class action lawsuits
-
Litigation that threatens core IP or licenses
-
Claims exceeding the company's value or coverage
-
Government enforcement actions with potential shutdown orders
In these cases, buyers must consider walking away or delaying the deal until legal clarity is achieved. Legal counsel plays a key role in evaluating whether the risks can be managed contractually or whether they fundamentally alter the business case.

Frequently Asked Questions (FAQs)
1. What types of litigation risks are most concerning during due diligence?
The most concerning litigation risks typically involve pending lawsuits, regulatory investigations, employment disputes, or IP infringement claims. These can significantly impact valuation, delay deal closure, or expose the buyer to post-closing liability. Class actions and government enforcement actions are especially serious.
2. Can a buyer avoid inheriting litigation risk by structuring the deal as an asset purchase?
While asset purchases allow buyers to exclude certain liabilities, they don't eliminate all litigation risk. Some liabilities-like environmental claims, employee lawsuits, or product liability-can follow the buyer under "successor liability" doctrines. Proper legal structuring and due diligence are necessary regardless of deal format.
3. How far back should a buyer review litigation history during due diligence?
Buyers should typically review at least five years of litigation history, though certain industries or risk profiles may warrant a longer look. Historical patterns, such as frequent disputes or regulatory violations, can indicate ongoing risk or cultural issues within the business.
4. What should be included in a litigation disclosure schedule?
A litigation disclosure schedule should include case names, docket numbers, parties involved, claims asserted, status of the case, amounts at issue, and insurance coverage details. It should also reference threatened litigation and regulatory inquiries, even if not formally filed.
5. What legal protections can a buyer use to reduce litigation risk post-closing?
Buyers can reduce post-closing litigation risk by negotiating indemnification provisions, reps and warranties, purchase price holdbacks, and escrow accounts. In some cases, rep and warranty insurance is also used to cover undisclosed claims or breaches.
