Due Diligence for Mergers & Acquisitions is the foundation of any successful M&A transaction in India. Before integrating two companies, a buyer must ensure that the target entity’s legal, financial, regulatory, and operational health is thoroughly assessed. Legal due diligence uncovers hidden liabilities, verifies representations, and protects the acquirer from unforeseen risks.
This article provides a structured guide on why due diligence matters, how to plan it, key areas to review, the process, best practices, common pitfalls, and India-specific considerations. It aims to help companies, investors, and legal advisors approach M&A in India with clarity and confidence.
Why Due Diligence Matters in M&A?
Due diligence is a critical step in any merger or acquisition. It helps buyers verify information, identify risks, and make informed decisions before completing a deal. By uncovering potential liabilities and assessing compliance, due diligence ensures a smoother transaction and protects the interests of all parties involved.
1. Information Asymmetry Reduction
M&A transactions often involve a buyer and seller with differing access to information. Due diligence levels the playing field by verifying the accuracy of what is presented.
2. Risk Identification
Due diligence reveals past or potential liabilities, including legal disputes, regulatory non-compliance, tax issues, intellectual property concerns, onerous contracts, and unsettled litigations. Identifying these risks is critical to accurate valuation and post-deal integration.
3. Valuation Accuracy & Deal Structuring
Thorough assessment of financial health, liabilities, assets, obligations, and contingencies allows the buyer to negotiate a fair price. It also informs appropriate indemnities, warranties, and deal structuring.
4. Integration Planning
Due diligence is forward-looking. Assessing operational, cultural, contractual, and regulatory fit enables smoother post-merger integration.
5. Trust Building
Cooperating fully in due diligence demonstrates transparency. For sellers, this can enhance buyer confidence and may result in a more favourable deal.
Given India’s complex business laws, regulatory regimes, and corporate structures, thorough due diligence is indispensable before any merger or acquisition.
Key Types of Due Diligence
A comprehensive M&A due diligence typically covers multiple dimensions:
1. Financial Due Diligence (FDD)
Analyses financial statements, historic performance, projections, debt, capital structure, receivables and payables, cash flows, order books, and internal controls.
2. Legal Due Diligence
Reviews corporate documents, contracts, ongoing and potential litigations, statutory compliance, licences and permits, intellectual property, employment agreements, contingent liabilities, material agreements, and shareholder structure.
3. Tax Due Diligence
Examines all tax obligations, past compliance, pending disputes, indirect taxes, and potential exposures.
4. Operational / Business Due Diligence
Evaluates commercial operations, business model, supply chains, contracts, market position, and competitive dynamics.
5. Intellectual Property & Asset Due Diligence
Confirms IP ownership, registration status, ongoing disputes, and intangible assets, particularly relevant for technology or asset-heavy businesses.
6. Regulatory, Compliance & Industry-Specific Due Diligence
Ensures the target complies with labour, environmental, and sector-specific regulations, licences, and approvals.
7. Human Resources / Cultural Due Diligence
Reviews employment contracts, HR policies, organisational structure, cultural fit, retention risks, and employee agreements.
Additional due diligence may cover IT, real estate, environmental, and other industry-specific considerations depending on the nature of the target business.
Planning the Due Diligence Process
Due diligence usually begins after the buyer’s offer is accepted, post Letter of Intent (LOI) or term sheet. This phase is critical as all assumptions must be verified before finalising the sale agreement.
How to Plan
- Define Scope and Objectives – Decide which areas require detailed review: finance, contracts, IP, compliance, operations.
- Assemble a Multidisciplinary Team – Include experts in law, finance, tax, HR, and operations. For cross-border deals, foreign-law counsel and regulatory advisors may be needed.
- Prepare a Detailed Checklist – Request financial statements, corporate records, board minutes, material agreements, employment and IP documents, licences, tax filings, and litigation history.
- Set Up a Secure Data Room – A virtual data room (VDR) allows secure exchange of confidential documents efficiently.
- Schedule Timeline and Responsibilities – Assign tasks, deadlines, and accountability for document collection, reviews, site visits, and interviews.
Step-by-Step Legal Due Diligence in India
Conducting legal due diligence in India requires a structured and methodical approach. This process involves reviewing corporate, contractual, regulatory, financial, and operational aspects of the target company to identify risks and ensure compliance. A step-by-step approach helps buyers make informed decisions, negotiate effectively, and plan for smooth post-merger integration.
1. Initial Data Request and NDA
After LOI, the buyer sends a detailed due diligence request list. Signing a Non-Disclosure Agreement safeguards sensitive data.
2. Data Room Set-up and Document Upload
The target uploads corporate records, financials, contracts, licences, IP data, HR records, and compliance certificates into the VDR.
3. Corporate and Legal Review
Legal counsel examines incorporation documents, memorandum and articles of association, board and shareholder resolutions, and shareholding patterns. Outstanding litigation, contingent liabilities, and material agreements are verified. Engaging a mergers and acquisitions law firm and attorneys in India at this stage ensures legal risks are identified early, obligations are properly assessed, and the buyer’s interests are protected throughout the deal process.
4. IP and Asset Verification
Confirm ownership of patents, trademarks, copyrights, domain names, licences, and pending registrations. Real estate, leased properties, and physical assets are checked for clear title and compliance with Indian law.
5. Regulatory, Compliance, and Tax Review
Check adherence to labour, environmental, sector-specific regulations, licences, permits, statutory filings, and approvals. Conduct thorough tax review of past filings, disputes, and indirect tax obligations.
6. Financial and Accounting Review
Verify historical financial statements, audits, internal controls, off-balance-sheet liabilities, receivables, payables, debt covenants, working capital, and cash flows.
7. Operational, Contracts, and HR Review
Examine material contracts, employment agreements, labour liabilities, and HR policies. Assess organisational structure, key personnel, management, retention risk, and cultural compatibility.
8. Interviews, Site Visits, and Verification
Engage management, employees, suppliers, and customers. Conduct site visits to verify operations, assets, and compliance on the ground.
9. Risk Assessment and Red-Flag Analysis
Identify potential deal breakers such as litigation exposure, regulatory non-compliance, hidden debts, IP risks, tax exposures, and HR or cultural challenges.
10. Due Diligence Report and Recommendations
Prepare a detailed report summarising findings, risks, mitigants, and recommendations. Use the report to guide SPA, deal structure, warranties, indemnities, escrow arrangements, and integration planning.
India-Specific Considerations
- Statutory and Regulatory Compliance – Ensure ROC filings, annual returns, GST and indirect tax compliance, labour and environment regulations, and sector-specific licences are in order.
- Tax and Indirect Tax Risk – Review income tax, GST, customs duties, advance tax, and disputed assessments.
- Contractual Obligations and Approval Clauses – Check change-of-control clauses, approvals, and restrictions to avoid post-sale surprises.
- IP Rights and Registrations – Verify trademarks, patents, copyrights, licensing agreements, and ongoing disputes with Indian authorities.
- Corporate Records and Board Resolutions – Ensure proper authorisations for corporate actions and compliance with governance standards.
- Employee and Labour Law Liabilities – Review bonus, gratuity, provident fund, ESOPs, and retention liabilities.
- Secure Virtual Data Room (VDR) – Critical for confidentiality, audit trails, and secure collaboration.
Legal due diligence in India often requires a cross-functional team of corporate lawyers, tax experts, compliance specialists, HR advisors, and industry-specific experts.
Common Pitfalls and Best Practices
- Incomplete or Inaccurate Data – Use a detailed checklist, insist on full disclosure, and include representations and warranties in SPA.
- Hidden Liabilities – Review litigation, tax history, regulatory filings, and creditor lists with external counsel if needed.
- Ignoring IP and Intangible Assets – Conduct dedicated IP due diligence and verify ownership and contractual encumbrances.
- Cultural or HR Mismatches – Assess retention risk, employee liabilities, and cultural compatibility.
- Operational or Regulatory Gaps – Engage local legal experts and verify compliance with Indian statutes.
- Poor Integration Planning – Use due diligence findings to design post-merger integration, operational alignment, and risk mitigation.
- Manual Document Handling – Use virtual data rooms for efficiency, security, and audit trail maintenance.
Best Practices for Effective Due Diligence
- Begin immediately after LOI or term sheet execution.
- Use a tailored checklist considering industry, size, and complexity of the target.
- Maintain confidentiality through a secure VDR.
- Engage a cross-functional team of experts.
- Obtain full disclosures with written confirmations and indemnities.
- Conduct site visits and interviews to verify operations and compliance.
- Use findings proactively to shape SPA, deal structure, and integration planning.
- Document all findings in a comprehensive due diligence report.

India’s regulatory landscape is complex and frequently changing. Legal due diligence is essential for:
- Cross-border transactions with foreign investment

Conclusion
Legal due diligence is not a formality. It is a strategic necessity for any M&A transaction in India. Thorough due diligence verifies material facts, uncovers risks, ensures realistic valuations, and enables successful post-merger integration. Whether a buyer, seller, or investor, investing time and resources in comprehensive due diligence safeguards value and reduces legal and financial exposure.
