Questions to Ask Any M&A Attorney Before Hiring

Use these before you call any firm, including ours.

1. "Who will actually handle my transaction?"

At many firms, a partner sells the work and a junior associate does it. Ask for the name of the attorney who will draft and negotiate your documents.

2. "How many M&A transactions has the lead attorney closed in the past 12 months?"

Volume indicates current, active deal experience, not just credentials from years ago.

3. "What is your experience with my deal size and industry?"

A $500K SBA acquisition and a $50M PE deal require different skill sets. Make sure the attorney has handled transactions similar to yours.

4. "Will you coordinate with my CPA, financial advisor, and broker?"

M&A transactions require a team. Your attorney should work with your other advisors, not in a silo.

5. "How do you handle post-closing disputes?"

Reps, warranties, and indemnification claims surface months after closing. Ask whether the firm handles post-closing litigation or refers it out.

6. "What is your fee structure, and what drives cost?"

Hourly, flat fee, or hybrid. Ask what factors increase legal costs so there are no surprises.

Frequently Asked Questions

Common questions from Barrington clients

What does a business sale attorney do?

A business sale attorney handles the legal side of buying or selling a business. This includes structuring the deal, conducting or managing due diligence, drafting and negotiating the purchase agreement, and coordinating the closing. At Acquisition Stars, Managing Partner Alex Lubyansky is personally involved in every transaction.

Do I need an attorney for a small business sale?

Yes. Even straightforward business sales involve purchase agreements, liability allocation, non-compete terms, and closing mechanics that carry real legal risk. The cost of experienced counsel is small compared to the cost of a poorly structured deal or a post-closing dispute that could have been prevented.

How much does a business sale attorney cost?

Legal fees depend on the size and complexity of the transaction. Acquisition Stars provides personal attention and 15+ years of M&A expertise with the managing partner on every deal. We discuss scope and structure during your initial engagement assessment.

Can you represent both the buyer and the seller?

No. Representing both sides in the same transaction creates a conflict of interest. We represent one party, either the buyer or the seller, and advocate exclusively for that client's interests throughout the deal.

How is Acquisition Stars different from a general business lawyer?

Our practice is focused exclusively on M&A transactions. Managing Partner Alex Lubyansky brings 15+ years of deal experience, which means we have seen and solved the issues that general practice attorneys encounter for the first time. You get specialized M&A counsel with the personal responsiveness of a boutique firm.

How do Illinois non-compete laws affect business sale transaction law transactions?

Restricted by the Illinois Freedom to Work Act (effective January 1, 2022). Non-compete agreements are prohibited for employees earning $75,000 or less annually (threshold increases by $5,000 every five years). Non-solicitation agreements are prohibited for employees earning $45,000 or less. Employers must advise employees to consult an attorney before signing, with a 14-day review period. The sale-of-business exception is preserved.

What are the Illinois tax considerations for selling a business?

Illinois imposes a flat 7% corporate income tax (including the 2.5% Personal Property Tax Replacement Income Tax). The state uses single-factor sales apportionment. Illinois does not allow combined reporting, which can be advantageous or disadvantageous depending on the target's entity structure. The state conforms to most federal treatment of acquisitions.

Does Illinois have a bulk sales law that affects business acquisitions?

Illinois has repealed UCC Article 6 (Bulk Sales). However, the Illinois Department of Revenue can impose successor liability on asset purchasers for the seller's unpaid sales, use, and withholding taxes under 35 ILCS 120/5j. Buyers must obtain a tax clearance letter (Form ST-4) before closing.

What can I expect during an initial consultation in Barrington?

During your confidential initial consultation in Barrington, we'll discuss your business sale transaction law needs, review your current situation, assess potential challenges specific to Illinois, and outline a clear path forward. We'll explain our process, answer your questions, and determine if we're the right fit for your needs.

Do you work with companies outside of Barrington?

Yes, we represent clients nationwide while maintaining a strong presence in Barrington. Our managing partner handles business sale transaction law matters across all 50 states, coordinating with local counsel where state-specific requirements apply.

M&A Market: Barrington & the Chicago Metro

Chicago is the Midwest's M&A powerhouse, with deep deal activity in manufacturing, food & beverage, financial services, and healthcare. The city's central location and transportation infrastructure make it a hub for logistics and distribution company acquisitions. Chicago's robust private equity community - including firms like GTCR, Madison Dearborn, and Duchossois Capital - drives significant lower middle-market deal flow.

Top M&A Sectors Near Barrington

Manufacturing
Food & Beverage
Financial Services
Healthcare
Logistics & Distribution

Deal Environment

Chicago offers a balanced deal market with strong fundamentals - valuations are more reasonable than coastal markets while target quality remains high. The region's manufacturing base creates consistent opportunities for PE-backed platform builds.

Why Acquire in the Chicago Area

The Chicago metro area's diversified economy and central location make it ideal for platform acquisitions with national expansion potential. The region's deep talent pool in engineering, finance, and operations supports post-acquisition growth.

Illinois Legal Considerations

Illinois enacted strict non-compete reform in 2022 - agreements are unenforceable for employees earning under $75,000 (increasing annually), and employers must advise employees to consult counsel before signing, affecting how buyers retain key personnel post-acquisition.
