Legal Due Diligence in M&A: What Founders Often Overlook

For many tech founders, the idea of getting acquired represents the ultimate validation—proof that years of product development, market fit, and hustle have paid off. But before any deal closes, there's one stage that can make or break the transaction: legal due diligence in M&A.

While financials and growth metrics often take center stage, legal due diligence plays a critical role in uncovering potential liabilities, verifying ownership rights, and ensuring compliance. Overlooking key legal aspects can delay—or completely derail—the deal.

In this blog, we’ll walk through the most commonly overlooked areas during legal due diligence, especially by startup founders, and how working with experienced M&A due diligence services can safeguard your exit strategy.

What Is Legal Due Diligence in M&A?

Legal due diligence is the process by which a buyer investigates the legal standing, obligations, and risks of a target company. It goes far beyond just reviewing contracts—it includes corporate governance, IP ownership, employment law compliance, regulatory issues, and more.

Buyers (and their legal advisors) want to ensure that:

• The company being acquired owns what it claims to own
  
  
• There are no hidden liabilities
  
  
• All agreements and operations are legally sound and transferable
  
  
• The acquisition won't be burdened by lawsuits, disputes, or compliance gaps
  
  

Failing to prepare for this process can lead to valuation drops, revised terms, or even deal cancellations.

What Founders Often Overlook in Legal Due Diligence

1. Intellectual Property (IP) Ownership

In the tech world, your IP is your business. Yet, many founders don’t maintain proper documentation showing clear ownership of code, trademarks, patents, or proprietary platforms. In some cases, former employees or contractors may hold IP rights due to poorly drafted contracts.

Why it matters:
Buyers need assurance that they are acquiring exclusive, uncontested rights to the technology. Any ambiguity can delay the deal or invite legal complications later.

2. Poorly Structured Cap Table

M&A deals often require a clean and well-documented capitalization table. Founders sometimes fail to update equity allocations, record convertible notes, or formalize vesting schedules.

Why it matters:
Confusion in equity distribution can lead to disputes among shareholders or even litigation, significantly complicating the closing process.

3. Unassigned or Verbal Agreements

Startups are known for moving fast, and that often means key partnerships or vendor deals are based on informal or verbal agreements. These become problematic during due diligence.

Why it matters:
Buyers need clarity and legal enforceability. Unwritten agreements can’t be audited, transferred, or enforced—making them liabilities rather than assets.

4. Employee Contracts and Compliance

Tech companies frequently offer stock options or flexible roles to attract talent. But missing employment contracts, unclear IP assignment clauses, or lack of labor law compliance can raise red flags.

Why it matters:
Misclassified employees, lack of confidentiality agreements, or poorly defined ESOPs can expose the acquiring company to legal and financial risks.

5. Pending or Undisclosed Litigation

Some founders underestimate the importance of disclosing all ongoing or past legal issues—even if they seem minor. Buyers view any undisclosed litigation as a sign of poor governance.

Why it matters:
Lawsuits, regulatory violations, or unresolved disputes—even if dormant—can resurface post-acquisition, affecting brand reputation and operational continuity.

6. Regulatory Non-Compliance

Startups working in fintech, healthtech, or other regulated sectors must adhere to local and international compliance standards. Founders often delay compliance procedures to “deal with later,” but buyers won’t overlook them.

Why it matters:
GDPR, HIPAA, or industry-specific regulations must be fully addressed and documented. Non-compliance can lead to hefty fines and reputational damage.

7. Customer and Vendor Contracts

A lack of clear terms in customer or vendor agreements—like payment terms, renewal clauses, SLAs, or exclusivity—can be problematic. Contracts that are non-assignable without consent can block the buyer from retaining those relationships.

Why it matters:
Every buyer wants a clear understanding of ongoing obligations and revenue streams. Unclear or non-transferable contracts can devalue the deal.
