Introduction

Buying a business is about far more than reviewing financial statements. A company may appear profitable while carrying contractual obligations, lease restrictions, employment issues, regulatory concerns, or other legal risks that are not immediately apparent.

Legal due diligence helps buyers identify these issues before closing. By understanding a business's legal obligations and potential liabilities early in the transaction, buyers can negotiate better terms, require problems to be corrected before closing, or decide that the risks outweigh the opportunity.

Key Takeaways

  • Financial due diligence and legal due diligence serve different purposes, and both are essential.
  • Contracts, leases, employment matters, corporate records, and regulatory compliance should all be reviewed before closing.
  • Identifying legal issues early often provides buyers with valuable negotiating leverage and helps avoid costly surprises after the acquisition.

What Is Legal Due Diligence?

Legal due diligence is the process of reviewing a company's legal affairs before an acquisition closes. The objective is to verify what the buyer is acquiring, identify potential liabilities, and evaluate risks that could affect the value or operation of the business after closing.

Unlike financial due diligence, which focuses on historical performance, legal due diligence examines the agreements, legal obligations, and relationships that govern the business.

The Areas Every Buyer Should Review

Material Contracts

Customer agreements, supplier contracts, software licenses, financing documents, and service agreements often contain assignment restrictions, change-of-control provisions, automatic renewals, and indemnification obligations. Buyers should confirm that key contracts will remain in place after closing and determine whether third-party consents are required.

Commercial Leases

For many businesses, the lease is one of the company's most valuable assets. Buyers should understand renewal options, operating expense obligations, rent escalations, maintenance responsibilities, and assignment provisions. Overlooking a lease restriction can delay closing or jeopardize the buyer's ability to operate at the location.

Employment Matters

Employment agreements, compensation arrangements, independent contractor classifications, confidentiality agreements, employee handbooks, and pending employment claims should all be evaluated. Buyers should also identify employees whose continued employment is critical to the business.

Litigation and Regulatory Compliance

Pending lawsuits, demand letters, government investigations, licensing requirements, privacy obligations, and other regulatory issues may not appear in financial statements but can significantly affect a company's value and future operations.

Corporate Records and Hidden Liabilities

Organizational documents, ownership records, board approvals, guarantees, tax obligations, indemnification agreements, and other contingent liabilities should be reviewed to confirm the business has been properly maintained and to identify obligations that could transfer to the buyer.

Harborview Insight

During the purchase of a retail business, a buyer focused primarily on revenue, inventory, and customer relationships. Legal due diligence later revealed that the company's commercial lease prohibited assignment without the landlord's consent. The issue was identified before closing, giving the buyer time to obtain the necessary approval and avoid a delay that could have jeopardized the transaction. While every transaction is different, this illustrates how legal due diligence can uncover issues that financial records alone would never reveal.

Common Mistakes Buyers Make

One of the most common mistakes is assuming financial performance reflects legal health. Another is waiting until the purchase agreement is nearly complete before beginning legal due diligence. Buyers also frequently rely solely on accountants, even though accountants and attorneys evaluate different categories of risk. Starting the legal review early allows buyers to identify issues while they still have meaningful negotiating leverage.

Frequently Asked Questions

What is legal due diligence?

Legal due diligence is the review of a business's contracts, leases, employment matters, litigation, corporate records, and legal obligations before an acquisition closes. Its purpose is to identify risks and help buyers make informed decisions.

What happens if legal issues are discovered?

Finding legal issues does not necessarily end the transaction. Buyers may negotiate a purchase price adjustment, require corrective action before closing, obtain additional contractual protections, or decide not to move forward.

Should an attorney review the purchase agreement?

Yes. The purchase agreement allocates risk between the buyer and seller. An experienced attorney can help ensure the agreement accurately reflects the results of the due diligence process and provides appropriate protections if problems arise after closing.

Conclusion

Successful business acquisitions depend on more than strong financial performance. Understanding a company's legal obligations before closing allows buyers to identify risk, negotiate more effectively, and protect their investment.

Harborview Law advises buyers, sellers, investors, and business owners throughout the acquisition process, from letters of intent and due diligence through purchase agreement negotiation and closing. Careful legal planning before closing can help reduce risk, preserve value, and position a transaction for long-term success.
