Published August 31st, 2026 by KHJ Law Team

Buying or selling a business is often the largest transaction of an owner’s life, larger sometimes than buying a home. Yet it is frequently done with far less due diligence than a house purchase. The legal work that goes in beforehand is what protects both sides.
Whether you are buying your first business or selling one you have spent decades building, the deal carries risks that are easy to underestimate when the parties are eager to close. The buyer wants to know exactly what they are getting. The seller wants to get paid and walk away cleanly. Careful legal due diligence and a well-structured agreement protect both of those goals.
At Klafehn, Heise & Johnson P.L.L.C., we guide buyers and sellers across Monroe, Orleans, and Genesee Counties through these transactions. Here is what the process involves and where the protection comes from.
One of the first and most consequential decisions is the structure of the deal. In an asset sale, the buyer purchases specific assets, such as equipment, inventory, customer lists, and the business name, and generally leaves the seller’s liabilities behind. In a stock or membership interest sale, the buyer purchases the entity itself, inheriting its assets and its liabilities together.
The choice has major legal and tax consequences for both sides, and buyers and sellers often have opposing preferences. Buyers usually favor asset sales to avoid hidden liabilities. Sellers often prefer stock sales for cleaner tax treatment. Getting the structure right, and negotiating it knowingly, is foundational to the whole transaction, and it shapes nearly every term that follows.
For a buyer, due diligence is the investigation that reveals what the business really is beneath the seller’s presentation. It typically includes a careful look at:
The purpose is to make sure there are no unpleasant surprises waiting after the closing, and to give the buyer the information needed to set a fair price or renegotiate. A problem found during due diligence is a bargaining point. The same problem found after closing is often a loss.
Considering buying or selling a business? Reach out to our office early, because the protections are most effective before the deal terms are locked in.
The purchase agreement is where the deal’s protections are written down. Beyond the price and what is being sold, a sound agreement addresses representations and warranties, which are the seller’s formal assurances about the business, how the purchase price is allocated, and what happens if those assurances turn out to be untrue. It often includes an indemnification provision allocating responsibility for problems that surface later, and frequently a non-compete or non-solicitation clause so the seller does not simply open a competing business down the road, subject to the limits New York places on such restrictions.
Due diligence is not only the buyer’s concern. A seller has real interests to protect too: making sure the buyer can actually pay, that any seller financing is properly secured, that the seller is released from business obligations and personal guarantees after the sale, and that the tax consequences are understood before signing rather than discovered at filing time. A seller who signs a buyer-drafted agreement without independent counsel can give away protections they did not know they had, and those protections are difficult to reclaim once the ink is dry.
Most business sales move through a recognizable sequence. The parties often begin with a letter of intent that sets out the basic terms, followed by a due diligence period, the negotiation and signing of a definitive purchase agreement, and finally a closing at which ownership transfers and funds change hands. Understanding that sequence helps both sides know what to expect, what is still negotiable at each stage, and where the points of no return lie, so no one feels rushed into a commitment they have not fully considered.
A business sale rarely stands alone. For a seller, the proceeds and the exit need to fit into an overall estate plan. If the business occupies real property, the building may be part of the deal or a separate lease arrangement. Coordinating these pieces, rather than treating the sale in isolation, produces a cleaner result for everyone involved.
One of the most common mistakes on both sides of a business deal is rushing. Eager buyers and motivated sellers sometimes want to move from a verbal agreement to a closing in a matter of weeks, before due diligence is complete or the agreement is properly drafted. Deals that are hurried are the ones most likely to produce disputes afterward. Building in enough time to investigate, negotiate, and document the transaction carefully is not a delay so much as an investment in a result that holds up. The work done patiently up front is what lets both parties move on cleanly once the deal is done.
