Selling a business is a complex process that requires careful planning and attention to detail.
One of the most critical phases of the transaction is due diligence—a period where the buyer thoroughly examines the business before finalizing the sale.
During this time, a lawyer plays a crucial role in ensuring the process runs smoothly and protecting the seller’s interests.
Understanding what a lawyer does during due diligence can help business owners prepare and navigate this stage with confidence.
1. Reviewing and Organizing Legal Documents
Buyers will request a variety of legal documents to verify the business’s legitimacy, compliance, and overall risk profile. A lawyer assists in gathering, reviewing, and organizing these documents, which may include:
Corporate formation documents (articles of incorporation, bylaws, operating agreements)
Business licenses and permits
Contracts with suppliers, customers, and employees
Leases and real estate agreements
Intellectual property (trademarks, patents, copyrights)
By ensuring that all documentation is up-to-date and accurate, the lawyer helps present the business in the best possible light to potential buyers.
2. Identifying and Addressing Legal Risks
A lawyer will proactively identify any legal risks that could become obstacles to the sale. These might include:
Pending or potential lawsuits
Regulatory compliance issues
Unresolved contract disputes
Employment law concerns, such as misclassified workers or unpaid wages
By addressing these risks early, sellers can prevent surprises that could delay or derail the sale process.
3. Handling Confidentiality and Non-Disclosure Agreements (NDAs)
Before sharing sensitive business information, sellers should have buyers sign a confidentiality or non-disclosure agreement. A lawyer drafts and negotiates these agreements to protect proprietary information and prevent competitors from misusing data obtained during due diligence.
4. Negotiating the Purchase Agreement
The purchase agreement is the most critical document in the transaction. A lawyer ensures that it reflects the seller’s best interests by assessing key terms such as:
Purchase price and payment structure (e.g., lump sum vs. installment payments)
Representations and warranties (statements about the business’s condition)
Indemnification clauses (protecting the seller from future liabilities)
Non-compete and non-solicitation agreements
Having a lawyer involved in this agreement minimizes the risk of unfavorable terms that could lead to post-sale disputes.
5. Ensuring Compliance with Regulatory and Tax Obligations
A lawyer helps ensure that the sale complies with all federal, provincial, and local regulations. This includes:
Tax implications of the sale, such as capital gains tax
Industry-specific regulatory approvals or licenses
Employee transition and benefits compliance
Failing to meet regulatory requirements could lead to fines, legal issues, or delays in closing the deal.
6. Overseeing the Closing Process
During the closing stage, a lawyer finalizes all necessary legal documents and ensures that all conditions of the sale are met. This includes:
Preparing final versions of the purchase agreement and related contracts
Coordinating with the buyer’s legal and financial teams
Ensuring proper transfer of ownership and assets
Once the transaction is complete, the lawyer helps resolve any post-closing obligations, such as releasing escrow funds or addressing any outstanding liabilities.
Final Thoughts
Selling a business is a major financial and legal undertaking.
Engaging an experienced lawyer early in the due diligence process can make the transaction smoother, reduce risks, and ensure that the seller achieves a fair and secure deal.
By understanding a lawyer’s role in due diligence, business owners can be better prepared and more confident as they move through the sale process.
