Legal due diligence for a small business acquisition
Short answer
Legal due diligence checks that the seller can sell what they're selling and that no legal problems come with it. For a small business that usually means confirming the entity is in good standing and the seller has authority to sell, searching for liens and judgments, reviewing litigation and regulatory history, reading key contracts and the lease for assignment terms, checking licences, intellectual property, employment practices and environmental issues. An attorney typically leads it alongside drafting the purchase agreement.

Checklist
Entity and authority
- Good standing certificate; formation documents; ownership records.
- Consents needed from owners or partners to sell.
Liens, judgments and taxes
- UCC, judgment and tax lien searches.
- Sales and payroll tax status.
Litigation and regulators
- Pending, threatened and past lawsuits; demand letters.
- Regulator inspections, audits, violations.
Contracts and lease
- Customer, supplier, franchise and equipment contracts: assignment, change of control, exclusivity.
- Lease. See lease assignment.
Licences and IP
- Licences and permits. See transferring licences.
- Trade names, trademarks, domains, software licences, content ownership.
Employment and environmental

Findings feed the reps and warranties and any escrow.
UCC lien search when buying a business
A UCC financing statement is a public filing a lender or creditor makes to record a security interest in a business's assets. Before buying a business, search the filings in the seller's state of organization (usually through the secretary of state) and anywhere else relevant, list every secured party, and arrange for each lien to be paid off and released at closing so you receive the assets free and clear. Many buyers also search for tax liens and judgments.
A lien search tells you who else has a claim on the assets you're buying. It's cheap, fast, and one of the first legal checks to run.
Reading the results
| Filing | What it means | Action |
|---|---|---|
| Bank, blanket lien | Business loan secured on all assets | Payoff letter, release |
| Equipment lender | Specific equipment financed | Pay off or exclude the item |
| Merchant cash advance | Advance against future receipts | Payoff; check earnings impact |
| Supplier | Inventory or trade credit | Confirm balance |
| Old paid-off loan | Never terminated | Ask for termination |
Merchant cash advances deserve a closer look: frequent advances can signal cash strain, and daily remittances may be hiding in the P&L.
Other searches
- Federal and state tax liens.
- Judgments.
- Searches under former business names and in each state where the business has assets.
Worked example: what a lien search turns up
Illustrative example, not a real business
A search in the seller's state of organization shows three UCC financing statements against the seller's company. One is from the bank that holds the line of credit, covering "all assets", which you knew about. One is from an equipment lessor covering a specific forklift, which tells you the forklift on the asset list is leased, not owned. The third is from a merchant cash advance company covering receivables, which the seller hadn't mentioned. The payoff list for closing grows by two items, the asset list shrinks by one, and you've learned the seller may have been short of cash. Each filing needs a payoff letter and a termination statement (UCC-3) at or right after closing, so the assets you buy come to you free of the liens. Your attorney or a search company should run UCC, judgment, tax lien and litigation searches in every relevant jurisdiction, and bring them down to the closing date.
Red flags legal diligence often finds
- The entity isn't in good standing, or the seller who signed the LOI doesn't own all of it.
- Contracts that can't be assigned without consents nobody has asked for.
- Pending or threatened lawsuits, or a pattern of customer or employee claims.
- Payroll tax or sales tax arrears, which can be serious and, in some states, can follow the assets.
- Intellectual property the business uses but doesn't own: a name someone else registered, software licensed to the owner personally.
- Permits in someone else's name, or a business operating without one it needs.
- Employee classification problems that could bring back taxes and penalties.
Findings feed the purchase agreement: specific representations, indemnities, closing conditions, a holdback or a price change. See reps and warranties. Not legal advice; your attorney sets the scope.
Asset deal vs stock deal: how legal diligence changes
In an asset purchase, legal diligence focuses on what you're buying: that the seller owns the assets free of liens, that contracts and leases can be assigned, that licences can be reissued, and that no liabilities will follow the assets under state law (some taxes and, in some states, bulk sale rules). In a stock or membership interest purchase, you inherit the whole entity, so diligence expands to everything it has ever done: tax filings for open years, employment claims, product or service liability, environmental history, past contracts and litigation. That's why stock deals usually carry heavier representations, larger indemnities and longer holdbacks. See asset vs stock purchase.
Questions your attorney will want answered
- Who exactly owns the selling entity, and do all owners agree to the sale?
- Which contracts, leases and licences need consent to assign or change control?
- Are there any lawsuits, claims, demand letters or regulator inquiries, past or threatened?
- Are payroll, sales and income taxes filed and paid, and has the business had any tax notices?
- Does the business own its name, website, software and other intellectual property?
- Are workers classified correctly, and are there any wage claims?
- Are there environmental, safety or permit issues at the premises?
Answers feed the purchase agreement's representations, indemnities and closing conditions. Give your attorney the full document list early; legal diligence takes longer when it starts late.
Searches to order, and what each one shows
| Search | Where | What it shows |
|---|---|---|
| Entity good standing | Secretary of state where formed and registered | The company exists, is current on filings, and who its officers are |
| UCC lien search | State filing office | Lenders and funders with a security interest in the assets |
| Federal and state tax liens | County and state records | Unpaid taxes secured on the assets |
| Judgment search | County courts | Unpaid court judgments against the company or the seller |
| Litigation search | State and federal court dockets | Pending or past lawsuits |
| Trademark search | USPTO records | Whether the business name and logo are registered, and to whom |
| Licence lookups | Each licensing agency | Status and discipline history of business and professional licences |
Run them twice: once in diligence, and a bring-down search just before closing, so nothing filed in between surprises you.
Employment and benefits: the legal items buyers miss
Employment issues are among the most common legal problems in small businesses, and many follow the business in practice even in an asset deal, because you keep the same people. Ask your attorney to look at worker classification (employees paid as contractors), overtime practices, wage and hour complaints, employment claims or charges filed with agencies, I-9 compliance, any retirement or health plan the business sponsors and its filings, and written policies or the absence of them. Get the seller's employment practices liability policy and claims history. Problems found here are often fixable before closing, and much harder to fix after.
Keep a single issues list from your attorney, with each item marked fix before closing, cover in the agreement, or accept. It turns findings into decisions.
Frequently asked questions
Do I need a lawyer to buy a small business?
Most buyers use one, because the purchase agreement allocates risk and the legal checks need judgment. OKtoBuy doesn't provide legal advice.
What searches are typical?
Entity status with the secretary of state, UCC lien searches, judgment and litigation searches, and tax lien searches, in the relevant states and counties.
Is legal due diligence different in a stock purchase?
It goes deeper, because the entity's history and liabilities come with it. In an asset purchase the focus is on the assets, their title and what can be assigned.
How do findings affect the deal?
Findings can be fixed before closing, covered by specific indemnities or escrow, priced in, or be reasons to walk away.
Where do I search for UCC liens?
Generally with the filing office in the state where the seller's entity is organized, usually the secretary of state. Some fixture filings are recorded with the county.
What does a blanket lien mean?
A filing that covers all of the business's assets, often from a bank or a merchant cash advance provider. It must be released before the assets transfer clean.
