M&A Attorney: Acquisition Counsel From LOI to Closing [2026]
An M&A attorney (mergers and acquisitions attorney) is a lawyer who represents buyers or sellers in business purchase and sale transactions. M&A attorneys handle deal structuring, Letter of Intent negotiation, legal due diligence, purchase agreement drafting and negotiation, and closing coordination. Unlike general business attorneys, M&A attorneys specialize in transaction-specific risks: liability allocation between buyer and seller, indemnification provisions, earn-out structures, and post-closing obligations.
Acquisition Stars provides M&A legal counsel for transactions from $500K to $50M. Managing partner Alex Lubyansky personally handles every engagement, from initial LOI review through closing and post-closing obligations. 15+ years of transaction experience. Nationwide practice based in Novi, Michigan.
Nationwide M&A counsel: Whether you are buying or selling a business, Acquisition Stars provides the transaction expertise your deal requires. Alex Lubyansky is your point of contact throughout. No associate hand-offs. No delays.

What Does an M&A Attorney Do?
An M&A attorney manages the legal workstreams of a business acquisition or sale, from the initial Letter of Intent through post-closing obligations. The scope of work covers six core areas.
1. Deal Structuring
Every acquisition starts with a structural decision: asset purchase, stock purchase, or merger. The structure determines your tax treatment, liability exposure, and closing complexity. An M&A attorney analyzes the specific transaction and recommends the structure that best protects the client.
- Asset purchase: Buyer selects specific assets and liabilities. Greater control and liability protection. Most common for small-to-mid-market deals.
- Stock purchase: Buyer acquires ownership shares and inherits all assets and liabilities. Used when the target has non-transferable contracts or licenses.
- Merger: Two entities combine into one. Used in larger transactions or when the deal structure requires continuity of both entities.
The wrong structure can create significant tax liabilities or leave the buyer responsible for the seller's undisclosed debts. This decision must be made early and correctly.
2. Letter of Intent (LOI) Drafting and Negotiation
The LOI sets the framework for the entire transaction: purchase price, deal structure, exclusivity period, key conditions, and the timeline for due diligence and closing. An M&A attorney drafts or reviews the LOI to lock in favorable terms before the buyer invests significant time and money in due diligence.
Critical LOI provisions include price and payment structure, exclusivity (no-shop) periods, due diligence scope and timeline, conditions to closing, and allocation of transaction costs. For a detailed breakdown, see our LOI template and guide for business acquisitions. For the distinction between an LOI and the final purchase agreement, see LOI vs. purchase agreement.
3. Legal Due Diligence
Due diligence is the investigative phase where the buyer's M&A attorney reviews the target's contracts, litigation history, regulatory compliance, intellectual property, employee matters, environmental liabilities, and corporate records. The goal is to identify risks that affect the purchase price, deal structure, or the decision to proceed at all.
An experienced M&A attorney manages the due diligence process efficiently, flags deal-breakers early, and negotiates price adjustments or indemnification protections for issues uncovered. For a comprehensive overview, see our complete guide to M&A due diligence. For the dedicated service page, see due diligence services.
4. Purchase Agreement Negotiation
The purchase agreement is the most important document in any acquisition. An M&A attorney negotiates every critical provision:
- Representations and warranties: Statements of fact that allocate risk between buyer and seller
- Indemnification: Caps, baskets, survival periods, and escrow terms that determine liability for breaches
- Working capital adjustments: Mechanisms to ensure the business has adequate cash at closing
- Earn-outs: Contingent payment structures tied to post-closing performance metrics
- Non-compete and non-solicitation covenants: Restrictions on the seller's post-closing activities
- Closing conditions: Regulatory approvals, third-party consents, and financing contingencies
This is where deals are won or lost. The purchase agreement determines what the buyer actually receives, what happens if problems surface after closing, and how disputes are resolved.
5. Ancillary Documents
Supporting documents that must align with the purchase agreement terms: employment agreements, transition services agreements, escrow agreements, seller notes, and consulting agreements. These documents are often where deals fall apart, particularly when key employee retention or seller transition involvement is critical to the business.
6. Closing and Post-Closing
The M&A attorney coordinates the closing process: managing the closing checklist, coordinating fund flows, collecting third-party consents, and ensuring all conditions precedent are satisfied. After closing, the attorney handles working capital true-ups, earn-out calculations, indemnification claims, and any post-closing disputes.
When You Need an M&A Attorney: Deal Stages Explained
M&A attorneys are involved throughout the entire lifecycle of a business acquisition. Here is when and why legal counsel matters at each stage.
Pre-LOI Stage
Before a Letter of Intent is signed, an M&A attorney helps structure the initial offer, review preliminary financials, assess deal feasibility, and advise on confidentiality agreements (NDAs). This is also when the attorney qualifies the counterparty, verifying proof of funds and confirming that the other side has the intent and ability to close.
LOI Stage
The LOI stage is where the economics and key terms are negotiated. An M&A attorney ensures that the LOI protects the client's position on price, structure, exclusivity, and due diligence scope. A well-drafted LOI prevents renegotiation later. A poorly drafted one invites it.
Due Diligence Stage
Legal due diligence typically runs 4 to 8 weeks. The M&A attorney reviews every material contract, identifies potential liabilities, assesses regulatory compliance, and works with the client's accountants and financial advisors to build a complete picture of the target. Issues uncovered during diligence directly inform the purchase agreement negotiation.
Closing Stage
The closing stage involves purchase agreement execution, fund transfers, regulatory filings, third-party consent delivery, and corporate resolutions. The M&A attorney manages the closing checklist and ensures that all conditions are satisfied before funds are released.
Post-Closing Stage
Post-closing obligations can extend 12 to 24 months after the deal closes. These include working capital true-ups, earn-out calculations, indemnification claims, and transition services oversight. An M&A attorney who structured the deal is best positioned to enforce the provisions they negotiated.
What to Look For in an M&A Attorney
Not all M&A attorneys are interchangeable. The right fit depends on your deal size, transaction complexity, and what level of attention you need. Five factors matter most.
1. Transaction Experience
How many M&A deals has the attorney personally handled? There is a significant difference between an attorney who has handled 5 deals and one who has handled 50+. Ask specifically about their experience with deals in your size range and industry. General litigation or corporate governance experience does not transfer to transactional work.
2. Who Actually Works Your Deal
At many firms, a partner sells the engagement and junior associates do the work. You meet the experienced partner during the pitch, then never see them again. Ask directly: who will be my day-to-day point of contact? Who drafts the purchase agreement? Who runs the due diligence process? At Acquisition Stars, managing partner Alex Lubyansky is personally involved in every transaction from LOI through closing.
3. Responsiveness
M&A transactions move fast. A two-day delay in responding to a counterparty's redline can stall a deal for weeks. Your M&A attorney needs to keep pace with the transaction timeline, respond quickly, and drive the process forward. If an attorney is slow during the engagement process, they will be slow during your deal.
4. Deal-Size Fit
An attorney who handles $500M transactions may not give a $5M deal the attention it requires. Conversely, an attorney who only handles small asset sales may lack the experience for a complex acquisition with earn-outs, regulatory approvals, and multi-state operations. Find an attorney whose typical deal size matches yours. For guidance on comparing your options, see our guide on business broker vs. M&A attorney.
5. Clear Fee Structure
You should understand the scope of work and expected fees before you engage. A good M&A attorney provides a detailed engagement scope, explains what is included, and identifies factors that could increase cost (complex diligence, regulatory approvals, contested negotiations). No surprises.
M&A Attorney Cost and Fee Structures
M&A attorney fees vary based on deal complexity, deal size, and the scope of legal work required. Understanding the common fee structures helps you evaluate proposals and budget appropriately.
Common Fee Structures
- Hourly billing: The attorney bills based on time spent. Common for complex transactions where the scope of work is difficult to predict upfront. Rates vary significantly based on the attorney's experience, firm size, and geographic market.
- Monthly retainer: A set monthly fee that covers a defined scope of work. Provides cost predictability for ongoing representation or transactions with extended timelines.
- Phased engagement: The engagement is broken into phases (LOI, due diligence, purchase agreement, closing) with separate scope and fees for each phase. This gives the client control over commitment at each stage.
- Success-based component: A portion of the fee is contingent on the deal closing. Aligns the attorney's incentives with the client's objective of getting the deal done.
Factors That Affect M&A Legal Costs
- Deal complexity: Multi-entity transactions, cross-border elements, or regulated industries increase the legal workload
- Due diligence scope: More contracts, more jurisdictions, and more regulatory issues mean more attorney hours
- Negotiation intensity: Contested provisions (indemnification, earn-outs, non-competes) require more rounds of drafting and negotiation
- Ancillary documents: Employment agreements, transition services, escrow arrangements, and seller notes each add to the scope
- Post-closing obligations: Working capital true-ups, earn-out disputes, and indemnification claims extend the engagement beyond closing
The right question is not "how much does an M&A attorney cost?" but "what is the scope of work, and what should I expect to pay for it?" A clear engagement scope prevents billing surprises and ensures you are comparing proposals on equal terms.
At Acquisition Stars, Alex Lubyansky provides a detailed scope of work and fee estimate after an initial assessment of your transaction. You understand the engagement before you commit.

Buy-Side vs. Sell-Side M&A Representation
The M&A attorney's role differs significantly depending on which side of the transaction they represent. Buy-side and sell-side counsel have different priorities, different risks to manage, and different negotiation objectives.
Buy-Side M&A Attorney
The buy-side attorney's primary objective is protecting the buyer from overpaying and from inheriting undisclosed liabilities. Key responsibilities include:
- Structuring the deal to minimize liability exposure (asset purchase vs. stock purchase)
- Conducting thorough legal due diligence to identify risks before closing
- Negotiating broad representations and warranties from the seller
- Securing indemnification protections with appropriate caps, baskets, and survival periods
- Building purchase price adjustment mechanisms (working capital, earn-outs) that protect the buyer
- Ensuring proper closing conditions and termination rights
Sell-Side M&A Attorney
The sell-side attorney's primary objective is maximizing proceeds while limiting the seller's post-closing exposure. Key responsibilities include:
- Preparing the business for sale by organizing corporate records and resolving outstanding legal issues
- Structuring the transaction to maximize after-tax proceeds
- Narrowing representations and warranties to limit post-closing risk
- Negotiating indemnification caps, baskets, and survival periods that protect the seller
- Managing the disclosure process to minimize the risk of post-closing claims
- Negotiating favorable escrow terms and earn-out structures
For a comprehensive breakdown of sell-side representation, see our sell-side M&A attorney guide. For sellers considering their exit timeline and preparation, see our business exit planning guide and exit planning services.
The Acquisition Process: LOI Through Closing
A typical business acquisition follows a structured process from initial offer through post-closing integration. Here is what each phase looks like, what to expect, and where legal counsel adds the most value.
Phase 1: Initial Assessment and Offer (Week 1-2)
The buyer identifies a target, reviews preliminary financials, signs a confidentiality agreement, and submits an initial offer or LOI. The M&A attorney reviews the LOI terms, recommends deal structure, and sets exclusivity provisions.
Key legal deliverable: Executed Letter of Intent with favorable exclusivity, structure, and conditions.
Phase 2: Due Diligence (Week 3-10)
The buyer's M&A attorney conducts legal due diligence, working alongside the buyer's accountants and financial advisors. The attorney reviews every material contract, identifies liabilities, assesses regulatory compliance, and flags issues that need resolution before closing.
Key legal deliverable: Due diligence report with risk assessment and recommended price adjustments or protections.
Phase 3: Purchase Agreement Negotiation (Week 8-12)
The purchase agreement is drafted and negotiated, incorporating findings from due diligence. This is typically the most intensive phase of legal work, involving multiple rounds of redlines on indemnification, representations, working capital, earn-outs, and closing conditions.
Key legal deliverable: Fully negotiated purchase agreement with all schedules and exhibits.
Phase 4: Pre-Closing and Closing (Week 12-14)
The M&A attorney manages the closing checklist: collecting third-party consents, coordinating with lenders, preparing corporate resolutions, managing fund flow arrangements, and ensuring all closing conditions are satisfied.
Key legal deliverable: Executed closing documents and confirmed fund transfers.
Phase 5: Post-Closing (Month 1-24)
Post-closing obligations include working capital true-ups (typically within 60-90 days), earn-out calculations (monthly or quarterly for 1-3 years), transition services oversight, and indemnification claims management.
Key legal deliverable: Working capital settlement, earn-out compliance monitoring, indemnification claim support.
Total typical timeline: 60 to 120 days from signed LOI to closing. Complex deals with regulatory approvals or multi-jurisdiction issues may take 4 to 6 months. According to industry research, 70-90% of M&A transactions fail to create expected value. Proper legal counsel throughout the process is one of the most effective ways to protect your investment.
Industry-Specific M&A Considerations
M&A legal work varies by industry. Contract structures, regulatory requirements, and common deal-breakers differ significantly across sectors. An M&A attorney with experience in your industry anticipates issues that a generalist would miss.
Franchise Acquisitions
Franchise transactions involve franchisor consent requirements, franchise disclosure document (FDD) review, territory restrictions, transfer fees, and compliance with FTC franchise rules. The franchisor can block the deal if the buyer does not meet their qualifications.
Healthcare Practice Acquisitions
Healthcare transactions involve HIPAA compliance, medical license transfers, insurance contract assignments, Medicare/Medicaid enrollment, Stark Law and Anti-Kickback Statute compliance, and patient record transitions. Regulatory failure can unwind the entire deal.
Technology and SaaS
Tech acquisitions involve intellectual property assignment and licensing, customer contract assignment, employee retention (key person risk), data privacy compliance (CCPA, GDPR), and SaaS revenue recognition. IP due diligence is often the most critical workstream.
Manufacturing
Manufacturing acquisitions involve equipment and facility assessments, environmental liability (Phase I and Phase II assessments), supply chain contract assignments, union and labor agreements, and product liability exposure. Environmental issues are the most common hidden cost.
Professional Services
Professional services acquisitions (accounting firms, consulting firms, agencies) center on client retention risk, key employee departures, non-compete enforceability, and earn-out structures tied to retained revenue. The asset being purchased is largely the workforce and client relationships.
Restaurants and Food Service
Restaurant acquisitions involve liquor license transfers, lease assignments, health department compliance, franchise requirements (for branded locations), equipment valuations, and employee transition. Lease assignment is often the gating item.
Acquisition Stars has transaction experience across all of these sectors. Alex Lubyansky works with industry-specific advisors (brokers, accountants, consultants) to ensure that legal counsel integrates with the broader deal team.
How Acquisition Stars Prevents the Three Things That Kill Deals
More deals die from these three behaviors than from bad economics. Here is how Acquisition Stars prevents each one.
Deal Fatigue
Deal fatigue happens when a transaction drags for months. Legal spend escalates, progress stalls, and one day someone just walks away. You need momentum and discipline to push through the M&A process.
How we prevent it: Alex drives deal timelines personally. Clear milestones from LOI through closing, weekly progress accountability, and the experience to know when something is stalling before it becomes fatal.
Over-Lawyering
Lawyers do, in fact, kill deals. Some attorneys jump in and fight every single thing on the front end, redlining every provision and souring the relationship so fast that the deal ends before it starts. M&A is transactional work meant to be collaborative, not adversarial litigation.
How we prevent it: Alex negotiates surgically. Fight the battles that actually protect you and leave the rest alone. A properly staged engagement resolves real issues early without destroying the deal relationship.
Tire Kicking
Some parties enter a deal without actual funding, backing, or intent. They use the process to gain free market information. If you don't qualify aggressively on the front end, you waste months and significant resources discovering a deal that was never going to happen.
How we prevent it: We qualify counterparties before significant time and money get spent. Verifying proof of funds, confirming financing commitments, and asking the hard questions in meeting one, not meeting five.
"The very best M&A attorneys are surgeons. They protect you from the legal side and let the rest of the deal team focus on their area of expertise. You wouldn't have a goalkeeper lining up at center mid. They take care of their job and do it at a monumentally successful level."

Frequently Asked Questions About M&A Attorneys
What does an M&A attorney do?
An M&A attorney handles the legal side of buying or selling a business. This includes deal structuring (asset vs. stock purchase), Letter of Intent drafting and negotiation, legal due diligence (reviewing contracts, liabilities, regulatory compliance, intellectual property), purchase agreement negotiation (indemnification, representations and warranties, working capital adjustments, earn-outs), drafting ancillary documents (employment agreements, non-competes, escrow agreements), and coordinating the closing. An M&A attorney differs from a general business attorney by specializing in transaction-specific risks: liability allocation, earn-out disputes, and post-closing obligations.
How much does an M&A attorney cost?
M&A attorney fees depend on deal complexity, deal size, and the scope of legal work required. Common fee structures include hourly billing, monthly retainers, and success-based components. Factors that affect cost include the number of legal issues uncovered in due diligence, the complexity of the purchase agreement, whether the deal involves multiple jurisdictions, and whether regulatory approvals are needed. The best approach is to get a clear engagement scope before committing. At Acquisition Stars, managing partner Alex Lubyansky provides a detailed scope of work and fee estimate after an initial assessment of your transaction.
When do I need an M&A attorney vs. a business attorney?
A general business attorney handles contracts, corporate governance, and routine legal matters. An M&A attorney specializes in the transaction process itself: structuring deals to minimize liability, negotiating purchase agreements with proper indemnification caps and baskets, managing due diligence across multiple workstreams, and coordinating closings with lenders, accountants, and counterparties. If your deal involves a purchase agreement (not just a bill of sale), earn-outs, seller financing, regulatory approvals, or employees and contracts that need to transfer, you need M&A-specific counsel.
How long does an M&A transaction take?
Most business acquisitions close in 60 to 120 days from a signed Letter of Intent. The typical timeline breaks down as follows: LOI negotiation takes 1 to 2 weeks, due diligence takes 4 to 8 weeks, purchase agreement negotiation takes 2 to 4 weeks, and closing preparation and execution takes 1 to 2 weeks. Transactions involving regulatory approvals, multiple jurisdictions, or complex earn-out structures may take 4 to 6 months. The most common cause of delay is due diligence. An experienced M&A attorney keeps the process moving and prevents deal fatigue.
What is the difference between an asset purchase and a stock purchase?
In an asset purchase, the buyer selects specific assets and liabilities to acquire, providing more control and protection from unknown liabilities. In a stock purchase, the buyer acquires ownership shares and inherits all assets and all liabilities, both known and unknown. Asset purchases are more common for small-to-mid-market deals because of the liability protection they offer. Stock purchases are used when the target has non-transferable contracts, licenses, or when the buyer wants operational continuity. Your M&A attorney structures the deal type based on your risk tolerance, tax implications, and operational needs.
Do I need an M&A attorney for a small business acquisition?
If the transaction involves a purchase agreement with representations and warranties, employees or contracts that need to transfer, earn-outs or seller financing, or a purchase price above $500K, then yes. The legal complexity of business acquisitions is not proportional to deal size. A $2M acquisition can have the same contract assignment issues, liability exposure, and indemnification needs as a $20M deal. The cost of M&A counsel is a fraction of the cost of a deal gone wrong.
What should I look for when hiring an M&A attorney?
Five things matter most. First, transaction experience: how many M&A deals has the attorney personally handled, and in what size range? Second, who actually works your deal: at many firms, a partner sells the work and junior associates do it. Third, responsiveness: M&A transactions move fast, and delays kill deals. Fourth, deal-size fit: an attorney who handles $500M deals may not give a $5M deal the attention it needs. Fifth, clear fee structure: you should understand the scope of work and expected fees before you engage.
What kills M&A deals most often?
Three behaviors kill more deals than bad economics. Deal fatigue occurs when a transaction drags on for months, legal spend escalates, and one party walks away. Over-lawyering happens when attorneys fight every provision aggressively and destroy the collaborative relationship that transactions require. Tire kicking is when one party enters the deal without actual funding or intent, using the process to gain free market information. An experienced M&A attorney prevents all three by driving timelines, negotiating surgically, and qualifying counterparties early.
Does Acquisition Stars handle deals outside Michigan?
Yes. Acquisition Stars handles M&A transactions nationwide. While based in Novi, Michigan, the majority of our transactions involve multi-state operations, out-of-state buyers or sellers, or businesses with national footprints. Managing partner Alex Lubyansky is admitted in multiple jurisdictions and coordinates with local counsel where state-specific requirements apply.
What is the role of an M&A attorney on the sell side?
On the sell side, an M&A attorney prepares the business for sale by organizing corporate records, resolving outstanding legal issues, and structuring the transaction to maximize after-tax proceeds. During the deal, the sell-side attorney negotiates the purchase agreement to limit the seller's post-closing exposure through indemnification caps, baskets, survival periods, and escrow terms. The sell-side attorney also manages the disclosure process to minimize the risk of post-closing claims. For a detailed breakdown, see our guide on sell-side M&A attorney representation.
