What to Look for in a Law Firm for Business Sales
Choosing the right law firm can make or break a deal. Before you sign an engagement letter, here are the key questions you should be asking:
1) Do they focus on small and mid-sized business deals?
Some firms are built for billion-dollar mergers. You want a firm that regularly handles transactions in the small-to-mid market, where the priorities and budgets are very different.
2) Have they worked on both the buy side and the sell side?
Experience matters. A firm that’s handled deals for both buyers and sellers knows the strategies and pitfalls on each side of the table.
3) Can they handle tax, employment, and regulatory issues too?
Buying or selling a business isn’t just about the purchase agreement — it often involves taxes, employee contracts, leases, and compliance. The best firms know how to cover the full picture.
4) Do they understand asset sales vs. stock sales?
These are two very different deal structures, each with unique risks and tax consequences. Your lawyer should be comfortable guiding you through both options.
5) Do they offer clear, predictable pricing?
Small businesses don’t have unlimited budgets. Look for a firm that provides flat fees, capped fees, or at least transparent billing so you don’t get blindsided by costs.

FAQs About Buying & Selling a Small Business
1) Do I need a lawyer to buy or sell a small business?
Yes. A lawyer protects your interests, drafts contracts, handles negotiations, and makes sure the deal complies with the law.
2) What’s the difference between an asset purchase and a stock purchase?
The buyer purchases selected assets (and sometimes liabilities) in an asset purchase. In a stock purchase, the buyer takes ownership of the entire company, including all assets and liabilities.
3) How much does legal help cost in a small business sale?
It depends on the complexity of the deal, but expect anywhere from a few thousand dollars for a simple transaction to tens of thousands for more complex sales.
4) Can one lawyer represent both buyer and seller?
Usually no. It’s a conflict of interest. Each party should have their own lawyer to ensure fair representation.
5) What’s the role of due diligence in a business sale?
Due diligence involves reviewing financials, contracts, leases, and liabilities to ensure there are no hidden surprises before closing the deal.
6) How long does it take to close a small business transaction?
Most deals close in 2–6 months, depending on financing, regulatory approvals, and the smoothness of negotiations.
7) What contracts are involved in selling a business?
Key agreements may include a purchase agreement, non-compete, employment contracts, lease assignments, and financing documents.
8) Do I need to involve tax advisors as well as lawyers?
Yes. A tax advisor helps structure the deal to minimize taxes, while your lawyer ensures legal compliance and protects your rights.
9) How do law firms protect me from hidden liabilities?
They review contracts, financials, and regulatory compliance issues, and structure the deal to limit exposure to undisclosed debts or lawsuits.
10) Can I use the same law firm for financing the purchase?
Often yes. Many firms also handle financing documents, loan agreements, and investor arrangements as part of the transaction.
