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 Oak Brook clients
What does an M&A attorney do?
An M&A attorney advises clients on all aspects of mergers and acquisitions, including transaction structuring, due diligence, contract negotiation, regulatory compliance, and closing. We represent buyers, sellers, and target companies in strategic transactions, private equity deals, and corporate restructurings.
How long does an M&A transaction take?
The timeline varies significantly based on transaction complexity, but typical M&A deals take 3-9 months from initial discussion to closing. Factors affecting timeline include due diligence scope, financing arrangements, regulatory approvals, and negotiation complexity.
Should I structure my acquisition as a stock purchase or asset purchase?
The choice depends on tax considerations, liability concerns, and transaction goals. Stock purchases are simpler but transfer all liabilities, while asset purchases allow selective acquisition of assets and liabilities but may trigger tax consequences. We analyze your specific situation to recommend the optimal structure.
What is due diligence in an M&A transaction?
Due diligence is the comprehensive investigation of a target company's legal, financial, operational, and commercial affairs. It helps identify risks, validate assumptions, inform purchase price, and shape deal terms. Thorough due diligence is essential for successful acquisitions.
How are M&A deals valued and priced?
Valuation methods include comparable company analysis, precedent transactions, discounted cash flow analysis, and asset-based valuation. Purchase price is negotiated based on valuation, market conditions, strategic value, and competitive dynamics. We work with financial advisors to ensure fair pricing.
How do Illinois non-compete laws affect mergers & acquisitions 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 a business acquisition or sale?
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 Oak Brook?
During your confidential initial consultation in Oak Brook, we'll discuss your mergers & acquisitions 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.

M&A Market: Oak Brook & 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.

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.
