Selling a business is one of the most significant financial events an owner will ever experience. For many entrepreneurs, it represents years — sometimes decades — of effort, risk, and personal investment. Yet business sales are rarely simple transactions. They involve legal rights, financial disclosures, regulatory requirements, and complex negotiations.
Because of that complexity, the process is not just a financial deal; it is a legal transaction. An experienced mergers and acquisitions (M&A) lawyer plays a central role in protecting the seller’s interests, guiding the process, and helping ensure the transaction closes smoothly.
Understanding what an M&A lawyer actually does can help business owners prepare properly and avoid costly mistakes when they decide to sell.
Preparing the Business for Sale
Long before a buyer signs a purchase agreement, preparation begins. Many sellers assume they should hire an attorney only after receiving an offer. In reality, legal preparation should start early.
An M&A lawyer helps owners evaluate whether the business is ready to be sold by reviewing:
- Corporate structure and ownership records
- Shareholder or operating agreements
- Existing contracts with customers and vendors
- Employment agreements
- Intellectual property ownership
- Pending or potential legal claims
During this stage, the attorney identifies issues that could delay or reduce the value of the transaction. For example, unclear ownership of intellectual property, unsigned contracts, or outdated corporate records can raise concerns for buyers and lenders. Addressing these matters in advance improves both marketability and negotiating leverage.
Structuring the Transaction
One of the first major decisions in a sale is determining the structure of the deal. Most transactions are either:
- Asset sales, where specific business assets are transferred, or
- Equity (stock) sales, where the buyer acquires the ownership interest in the company itself.
The choice significantly affects taxes, liability exposure, and future obligations.
An M&A lawyer advises the seller on which structure best protects their interests. Buyers often prefer asset purchases because they can avoid certain liabilities. Sellers, however, may prefer equity sales to simplify the transaction and potentially receive more favorable tax treatment. Negotiating this issue early can materially impact the seller’s net proceeds.
Negotiating the Letter of Intent (LOI)
After preliminary discussions, buyers typically present a Letter of Intent (LOI). While often described as “non-binding,” the LOI is extremely important. It establishes the framework for the deal, including:
- Purchase price
- Payment structure
- Exclusivity period
- Due diligence timeline
- Conditions to closing
Many sellers underestimate the significance of this document. Certain provisions — such as exclusivity clauses — can limit the seller’s ability to negotiate with other buyers. An M&A attorney reviews and negotiates the LOI to ensure the terms are fair and do not inadvertently weaken the seller’s position.
Managing Due Diligence
Due diligence is frequently the longest and most demanding phase of a business sale. During this process, the buyer investigates the company to verify its financial condition, operations, and legal compliance.
Buyers may request:
- Financial statements
- Tax returns
- Customer contracts
- Employee records
- Licenses and permits
- Litigation history
Your M&A lawyer coordinates the legal portion of this process. They help organize disclosures, review requested documents, and ensure confidential information is shared appropriately. Importantly, they also prevent over-disclosure that could expose the seller to unnecessary risk.
Attorneys often prepare or review confidentiality agreements and assist in creating disclosure schedules, which become part of the final purchase agreement.
Drafting and Negotiating the Purchase Agreement
The purchase agreement is the core legal document of the transaction. It can easily exceed 50–100 pages and contains provisions that determine the seller’s post-closing obligations and liability exposure.
An M&A lawyer negotiates critical sections such as:
Representations and warranties:
Statements about the business’s condition. If inaccurate, they can lead to claims against the seller after closing.
Indemnification provisions:
Define when the seller must compensate the buyer for losses.
Escrow or holdback terms:
A portion of the purchase price may be withheld to cover potential claims.
Non-compete clauses:
Limit whether and how the seller can start a competing business.
Without careful review, sellers may unknowingly agree to broad obligations that expose them to financial liability years after the sale. The attorney’s role is to narrow these provisions to reasonable and manageable limits.
Addressing Employment and Transition Issues
Business sales frequently involve employees, management teams, and ongoing client relationships. An M&A lawyer helps address:
- Retention agreements for key employees
- Consulting or transition agreements for the seller
- Assignment of customer contracts
- Benefit plan considerations
Many buyers request that the seller remain involved for a transition period. The attorney negotiates compensation, duration, and responsibilities to avoid misunderstandings after closing.
Regulatory and Compliance Matters
Depending on the industry, government approvals or filings may be required before the sale can close. These may include:
- Licensing transfers
- Antitrust filings in larger transactions
- Third-party contract consents
- Professional regulatory approvals
An M&A lawyer identifies required approvals and ensures deadlines and conditions are satisfied, preventing last-minute delays.
Closing the Transaction
The closing is the final stage where ownership transfers and payment occurs. However, reaching closing requires coordinating numerous documents, including:
- Bills of sale
- Assignment agreements
- Corporate resolutions
- Certificates and legal opinions
Your attorney oversees the closing process, confirms that conditions are satisfied, and ensures funds are transferred correctly. They also verify that post-closing obligations are clearly defined.
Post-Closing Protection
The lawyer’s role does not end at closing. Many purchase agreements include post-closing provisions such as:
- Earn-out payments
- Escrow releases
- Non-compete enforcement
- Indemnification claims
An M&A attorney helps the seller respond to buyer requests, resolve disputes, and protect remaining financial interests.
Why Legal Guidance Matters
Selling a business is not simply finding a buyer and signing documents. The transaction involves risk allocation. Every clause in the purchase agreement determines who bears a particular risk — the buyer or the seller.
An experienced M&A lawyer works to:
- Maximize the seller’s financial outcome
- Limit post-closing liability
- Maintain confidentiality
- Prevent avoidable disputes
Without proper representation, sellers may accept unfavorable terms, incur unexpected tax consequences, or remain liable for obligations long after receiving payment.
Conclusion
A business sale represents the culmination of an owner’s hard work and investment. While financial advisors and brokers help identify buyers and value the company, the M&A lawyer ensures the transaction is legally sound and protects the seller’s interests.
From preparation and negotiation to closing and beyond, the attorney acts as both strategist and safeguard. By guiding the structure, reviewing disclosures, negotiating the purchase agreement, and managing risk, an M&A lawyer helps turn a complex transaction into a successful exit.
For business owners considering a sale, involving experienced legal counsel early in the process is one of the most important steps toward achieving a secure and profitable transition.
