Mid-sized companies rarely enter a merger or acquisition expecting the deal to end in court. Yet a substantial share of commercial litigation between businesses traces back to a transaction that closed months or even years earlier on terms nobody examined closely enough. The resulting claims look varied on the surface, involving breach of warranty, fraudulent inducement, unpaid earnouts, or unenforceable restrictive covenants, but they usually share a single root cause: something material was never verified or never written down with precision. Business acquisition due diligence is the discipline that closes that gap, and it produces the best results when it begins well before a letter of intent is signed. The sections that follow outline where regional transactions most often break down and what a rigorous pre-closing review can do about it.
Hidden Liabilities Buyers Inherit
The most expensive post-closing surprises are almost never exotic. They are unfiled state tax returns, workers misclassified as independent contractors, lapsed professional licenses, software or designs created by former contractors that were never assigned to the company, and customer contracts that terminate automatically on a change of control. Buyers frequently assume that an asset purchase leaves the seller’s obligations behind, but Virginia recognizes several exceptions to that rule, including situations where the buyer expressly or impliedly assumes liabilities and where the transaction operates as a de facto merger. Customer concentration is another blind spot worth quantifying early, because a target that draws forty percent of its revenue from two accounts with terminable contracts is a very different asset than its financial statements suggest. Environmental conditions, unrecorded easements, and lease assignment provisions deserve the same scrutiny in deals involving manufacturing sites, warehouses, or commercial real property. Every one of these issues is discoverable before closing, and every one of them becomes a lawsuit when it is discovered afterward.
Restrictive Covenants Under Virginia Law
Non-compete and non-solicitation provisions generate a disproportionate share of post-sale litigation because buyers tend to assume the covenants they acquired are enforceable. Virginia does not permit blue penciling, which means a court will strike an overbroad covenant in its entirety rather than narrow it to something reasonable. The statutory limits have also tightened steadily: Va. Code § 40.1-28.7:8 has barred covenants with low-wage employees since 2020, a 2025 amendment expanded that category to include every employee entitled to overtime under the Fair Labor Standards Act, and the 2026 earnings threshold sits at roughly $1,507 per week. Senate Bill 170, effective July 1, 2026, goes further by rendering a non-compete unenforceable against any employee discharged without cause unless the employer provides severance or other monetary payment that was disclosed when the covenant was executed. The amendment does not expressly carve out covenants signed in connection with the sale of a business, which matters a great deal when a selling owner stays on as an employee after closing. Virginia applies a more relaxed reasonableness standard to covenants ancillary to a business sale than to ordinary employment covenants, so which agreement the restriction lives in can determine whether it survives a challenge. With civil penalties reaching $10,000 per violation and a private right of action available to employees, covenant review is no longer a secondary item on the checklist.
Buy Sell Agreements Left Unrevised
Many closely held companies adopted a buy-sell agreement at formation and never revisited it. When an owner dies, divorces, becomes disabled, or simply wants out, that document controls valuation, funding, and timing, and stale terms are among the most reliable predictors of shareholder litigation. Typical defects include a fixed price per share set a decade ago, a valuation formula tied to a revenue model the business abandoned, no funding mechanism at all, and life insurance that has lapsed or is owned by the wrong party for tax purposes. Ambiguity about triggering events causes equal damage, particularly around what qualifies as a disability, what happens when an interest passes to a creditor or a former spouse, and whether a transfer to a family trust requires consent. Deadlock and exit provisions are often missing entirely in two-owner companies, leaving dissolution as the only remaining remedy. Treating these documents as a live component of business acquisition due diligence, rather than as background paperwork, costs very little compared to a contested valuation fight. The agreement should also be reconciled against the operating agreement, the bylaws, any lender covenants, and the owners’ estate plans, since inconsistencies among those documents create their own litigation.
Drafting That Anticipates Disputes
Representations and warranties are the mechanism by which parties allocate the risk of facts turning out to be wrong, and their value depends entirely on how they interact with the indemnification provisions that follow. Caps, baskets, deductibles, survival periods, and escrow amounts should be negotiated as a single structure, because a robust warranty paired with a twelve-month survival period and a low cap offers far less protection than it appears to. Fraud carveouts and non-reliance clauses warrant particular care, since they determine whether a buyer can step outside the contractual remedy scheme and pursue tort claims that bypass the negotiated limits. Earnout provisions require the accounting methodology, the buyer’s post-closing operating obligations, seller audit rights, and an expert determination process to be spelled out in detail, because information asymmetry after closing makes these terms unusually litigation prone. Working capital adjustments deserve the same treatment, and deal points research from the American Bar Association has identified working capital disputes as the most frequent category of post-closing claim. Governing law, venue, notice requirements, and fee shifting should be settled deliberately rather than copied from a prior deal. Precision at the drafting table is consistently cheaper than argument in a courtroom.
Building A Repeatable Review Process
Effective review starts before the letter of intent, when there is still leverage to reprice, restructure, or walk away. A document request list should be scaled to the size and industry of the transaction and coordinated with the client’s CPA, insurance broker, and lender so that findings are cross checked rather than siloed. Disclosure schedules are the practical heart of the process, and sellers who disclose thoroughly generally fare better than sellers who disclose sparingly, because an accurately scheduled exception is a resolved issue rather than a breached warranty. Sellers benefit from running the same review on themselves before going to market, since problems identified early can usually be corrected, while problems identified by a buyer become price concessions. Representation and warranty insurance now appears in a majority of private deals studied by the American Bar Association, but it does not cover matters the parties already knew about, which makes the timing and quality of the underlying review more important rather than less. Finally, the work should end with an organized closing binder and a defined integration plan, because obligations that survive closing are only useful if someone is tracking them.
Counsel Before And After Closing
Litigation after a sale is rarely a matter of bad luck. It is nearly always the consequence of a question nobody asked or an ambiguity nobody bothered to resolve while the parties were still cooperating. Mitchell Kilgore works both sides of that equation, structuring and closing transactions for businesses across Southwest Virginia while also litigating commercial disputes when they arise, which means the agreements we draft reflect how these cases actually unfold in court. Whether you are acquiring a competitor, selling to a strategic buyer, or bringing in a new partner, thorough business acquisition due diligence is the most reliable protection available, and our team is ready to begin that conversation.
