Why the attorney’s role matters
Buying a business is not a single purchase. It can involve assets, contracts, intellectual property, employees, leases, licenses, debt, tax allocations, and promises about what happens after closing. A handshake understanding may be commercially clear while leaving important legal questions unanswered.
The attorney’s job is to convert the negotiated business terms into documents that say exactly what is being purchased, what is excluded, which conditions must be satisfied, and who bears the cost if a representation proves wrong.
What a business acquisition attorney typically does
1. Reviews the letter of intent
The lawyer identifies which provisions are binding, such as confidentiality, exclusivity, access, expenses, and governing law. Clear LOI language reduces the chance that both sides spend weeks negotiating under different assumptions.
2. Helps choose and document the structure
An asset purchase and an equity purchase transfer different rights and liabilities. Counsel coordinates with the buyer’s tax advisor to reflect the selected structure. In many asset acquisitions, buyer and seller must report the allocation of consideration using IRS Form 8594.
3. Conducts legal due diligence
Counsel reviews entity records, ownership, liens, litigation, permits, contracts, leases, employment matters, intellectual property, and claims. The objective is not simply to list issues. It is to determine whether an issue blocks closing, changes price or structure, requires consent, or should be covered by an indemnity, escrow, or holdback.
4. Drafts and negotiates the purchase agreement
The agreement defines purchased assets or interests, excluded items, price and adjustments, representations, covenants, closing conditions, remedies, and post-closing obligations. The lawyer also coordinates bills of sale, assignments, seller notes, security documents, transition agreements, and restrictive covenants when appropriate.
5. Coordinates third-party approvals
Landlords, lenders, franchisors, vendors, customers, and government agencies may need to approve an assignment or ownership change. Counsel tracks these conditions and ensures that a buyer does not close while a critical right remains nontransferable.
6. Manages the closing process
The lawyer organizes signatures, payoff letters, releases, funds flow, certificates, and deliverables. In California business transactions, escrow may also coordinate funds and documents, but escrow follows written instructions and does not replace either party’s legal counsel.
What the attorney usually does not do
- Verify normalized earnings or prepare a quality-of-earnings analysis
- Determine market value or select the buyer’s offer price
- Inspect equipment, inventory, cybersecurity, or operations
- Guarantee that customers or employees will remain
- Provide tax advice unless specifically qualified and engaged to do so
A strong buyer team usually includes legal, accounting, lending, insurance, and operational expertise. Each advisor should have a defined scope.
When should the buyer hire counsel?
Ideally, before signing a letter of intent. Early review is usually less expensive than correcting a structural mistake after the buyer has committed time, money, and negotiating leverage. At minimum, counsel should be involved before the purchase agreement, lease assignment, seller financing documents, or other binding obligations are signed.
Questions to ask before hiring an attorney
- How many small-business acquisitions have you handled recently?
- Do you regularly represent buyers in asset purchases, equity purchases, or both?
- Who will do the work, and how are fees structured?
- What is included in diligence, document drafting, negotiation, and closing?
- How do you coordinate with the CPA, lender, broker, and escrow holder?
- What information do you need before reviewing the LOI?
Frequently asked questions
Can the buyer use the seller’s attorney?
Usually no. The buyer and seller have different interests in risk allocation, remedies, and disclosure. Each side should understand whom the attorney represents.
Is an attorney required to buy a small business?
Requirements vary by jurisdiction and transaction. Even when not legally required, legal review can be valuable because purchase agreements, leases, licenses, and liabilities may affect the buyer long after closing.
How much does a business acquisition attorney cost?
Fees vary with deal size, complexity, geography, and whether the transaction is negotiated from a standard form or drafted extensively. Ask for a written engagement letter and estimated scope rather than choosing only by hourly rate.
Bottom line
A business acquisition attorney protects the buyer by making the transaction clear, transferable, and enforceable. The best time to involve counsel is early enough for legal findings to influence the deal—not after the major terms have hardened.
