Buying a company involves more than checking its revenue, customers and profitability. Company acquisition due diligence is the legal process through which a buyer examines the target company’s ownership, contracts, liabilities, regulatory compliance, disputes, intellectual property, employees and other legal affairs before completing the transaction. A company can appear financially attractive while carrying undisclosed litigation, defective share ownership, restrictive contracts, tax exposure or regulatory problems. These issues can affect the purchase price, transaction structure and liabilities assumed by the buyer. In India, acquisition diligence can involve the Companies Act, competition law, securities regulations, foreign exchange rules, insolvency law, employment legislation, intellectual property statutes and sector specific regulations. The precise scope depends on the target, buyer, transaction structure and industry.
Why is legal due diligence important before buying a company?
Legal due diligence allows the buyer to understand what is actually being acquired. A company’s balance sheet may show assets, but it may not reveal whether the company has good title to those assets. Financial statements may show revenue, but they may not reveal whether a major customer can terminate its contract after a change in control. Similarly, a company may own valuable technology in commercial terms while the underlying patent or software rights legally belong to a founder, former employee or third party. This is why legal diligence should not be treated as a document collection exercise. The objective is to identify legal issues capable of affecting value, ownership, operations or the buyer’s future liability. Current Indian M&A guidance also increasingly treats legal diligence as a multidisciplinary review covering corporate, contractual, regulatory, employment, intellectual property and litigation risks.
Start with the company’s corporate records
The first review should establish whether the target company legally owns what the seller proposes to sell. The buyer should examine the certificate of incorporation, memorandum and articles of association, share capital records, registers, board minutes, shareholder resolutions and statutory filings. The shareholding history requires particular attention. The buyer should establish who legally owns the shares, whether previous transfers were properly completed and whether any shares are subject to pledges, liens, options or other restrictions. The company’s filings with the Ministry of Corporate Affairs should also be reviewed alongside its internal records. Differences between statutory filings and management representations can indicate unresolved corporate issues. The review should also identify subsidiaries, associate companies, joint ventures and material investments. A buyer may otherwise acquire a parent company without fully understanding liabilities sitting elsewhere in its corporate structure. For statutory corporate information, the Ministry of Corporate Affairs provides the relevant regulatory framework and corporate filing systems.
Verify the seller’s authority to sell the shares
The buyer should confirm who has authority to transfer the shares. This sounds straightforward, but ownership can become complicated where there are multiple founders, historical investments, employee options, convertible instruments or family holding arrangements. The transaction documents should match the company’s statutory records. The buyer should also check shareholder agreements and articles of association for pre emption rights, transfer restrictions, drag rights, tag rights, investor consent requirements and other contractual limitations. If a third party has a right to acquire the shares before the proposed buyer, the transaction may not proceed in the proposed form. A clean share title is therefore one of the most important conditions for a share acquisition .
Review existing contracts carefully
Material contracts can determine the practical value of a business. The buyer should review major customer agreements, supplier arrangements, distribution agreements, technology licences, franchise agreements, leases, loan documents, joint venture agreements and long term service contracts. The review should focus not only on commercial terms but also on change of control provisions. Some contracts allow the other party to terminate, renegotiate or require consent when ownership or control changes. Others may contain assignment restrictions. A company may therefore have a profitable customer contract today but lose part of its expected revenue after the acquisition if the customer has a contractual termination right. Contracts should also be checked for exclusivity, minimum purchase obligations, indemnities, unusual warranties, liability caps, renewal terms and termination rights.
Examine pending and threatened litigation
Litigation can create liabilities extending well beyond the amount mentioned in a current claim. The buyer should review pending civil proceedings, commercial disputes, arbitration matters, consumer proceedings, employment disputes, intellectual property claims, regulatory proceedings and tax litigation. Court searches should be considered alongside information provided by management. A management declaration alone may not reveal every proceeding. The buyer should also examine legal notices and threatened claims. A dispute does not become irrelevant simply because no formal suit has yet been filed. The nature of the relief sought is important. A monetary claim is different from an injunction affecting the company’s ability to use intellectual property, occupy premises or perform a key contract. Recent Indian due diligence commentary has highlighted independent litigation searches as an important part of acquisition review.
Check licences, registrations and regulatory approvals
Many businesses depend on statutory licences or sector specific approvals. The buyer should identify every material approval required for the target’s business and verify its validity, renewal status and transferability. The review may include registrations under company law, tax laws, environmental regulations, food and drug laws, financial services regulation, telecommunications law, manufacturing rules or other sector specific legislation. The buyer should also determine whether the acquisition itself requires regulatory approval. A licence held by the target may not automatically transfer to a new owner. Some regulatory regimes may require prior approval or post transaction notification. This issue becomes more significant when the company operates in a regulated sector.
Review tax liabilities and disputes
Tax diligence should operate alongside legal diligence. The buyer should examine income tax assessments, GST records, withholding obligations, tax notices, appeals, transfer pricing matters and outstanding demands. Historical non compliance can remain relevant after an acquisition, particularly in a share purchase where the corporate entity continues to own its historical liabilities. The buyer should also examine related party transactions and unusual tax positions. A tax exposure does not necessarily mean the transaction should stop. It may instead affect the purchase price, indemnity provisions, escrow arrangements or conditions before closing. The important point is to quantify the issue rather than merely identify it.
Examine intellectual property ownership
For many modern businesses, intellectual property may be one of the most valuable assets being acquired. The buyer should identify patents, trade marks, copyrights, domain names, software, designs, databases, trade secrets and other important intellectual property. Ownership should then be verified. For example, software may have been developed by employees or outside developers. The relevant employment or consultancy agreements should establish whether the company obtained the necessary rights. Trade marks and patents should also be checked against registration records and licence agreements. Third party licences deserve particular attention. A company may use important technology without owning it. The buyer needs to understand whether the licence survives a change in ownership. Recent Indian commentary on IP diligence also highlights ownership, licensing and infringement risks as distinct areas requiring review.
Review employment and labour law compliance
Employees can represent both value and liability. The buyer should examine employment agreements, compensation structures, senior management arrangements, employee benefits, incentive plans, confidentiality obligations and pending employment disputes. The review should also consider statutory social security and employment related obligations. India’s labour framework changed materially with implementation of the four Labour Codes from 21 November 2025. The Ministry of Labour and Employment states the Codes consolidated 29 central labour laws into four principal Codes. The buyer should therefore assess the target’s current compliance position under the applicable labour framework, along with relevant state rules and sector specific requirements. Employee retention can also be a transaction issue. Key personnel may have contractual rights, change in control provisions or incentives capable of affecting post acquisition continuity.
Examine loans, guarantees and security interests
The buyer should establish the company’s complete debt position. This includes bank loans, working capital facilities, debentures, shareholder loans, guarantees, letters of credit and other financial commitments. Security created over company assets should also be identified. The buyer should determine whether lenders have consent rights relating to the proposed acquisition or change of control. A company can appear debt free from an operational perspective while having contingent liabilities through guarantees given to subsidiaries, promoters or related entities. These liabilities need to be assessed before the transaction is signed.
Check related party transactions
Transactions with promoters, directors, shareholders and connected businesses deserve careful review. The buyer should identify loans, guarantees, leases, purchases, sales, service arrangements and other dealings with related parties. The purpose is not to assume such transactions are improper. The objective is to understand whether the target depends on arrangements capable of changing after the acquisition. For example, a company may occupy property owned by a promoter. It may receive services from a promoter controlled entity. It may rely on a shareholder loan for working capital. After acquisition, these arrangements may need to be replaced or renegotiated. The buyer should therefore identify the commercial dependence as well as the legal compliance position.
Review real estate and asset ownership
Where property is important to the business, title diligence should be undertaken separately. The review may cover ownership documents, leases, licences, encumbrances, mortgages, land use permissions, building approvals and disputes concerning possession or title. For leased premises, the buyer should examine the lease term, renewal rights, rent escalation, security deposit, assignment provisions and change of control clauses. For owned property, title documents and encumbrance records should be reviewed. Plant and machinery should also be assessed where they are material to the business. The buyer should verify ownership, financing arrangements and any security interests.
Check insolvency and financial distress issues
A target facing serious financial distress requires additional diligence. The buyer should determine whether the company has received insolvency notices, whether any proceedings are pending before the National Company Law Tribunal, whether creditors have initiated recovery proceedings and whether the target has material defaults. The Insolvency and Bankruptcy Code can materially affect acquisition structures involving distressed companies. If the proposed acquisition involves an insolvency resolution process, the buyer also needs to consider the specific statutory framework governing resolution applicants, plans and treatment of existing liabilities. An acquisition of a distressed company should not be approached in the same way as a routine solvent company acquisition.
Assess competition law requirements
Competition law can become relevant even when the transaction is structured as a share purchase. The Competition Commission of India treats qualifying acquisitions, mergers and amalgamations as combinations subject to the statutory framework. Not every transaction requires notification, but transactions meeting the relevant criteria can require approval before consummation. The Competition Act framework now includes a deal value threshold. The CCI explains that the 2023 amendments introduced a ₹2,000 crore transaction value threshold where the target has substantial business operations in India. A buyer should therefore assess competition law early rather than waiting until signing. The target’s market position, the buyer’s existing businesses and the transaction value may all affect the analysis.
Consider SEBI requirements for listed companies
Buying a listed company involves a separate regulatory layer. The SEBI Takeover Regulations govern substantial acquisition of shares, voting rights and control in listed companies. The regulations were last amended on 5 December 2025 according to SEBI’s current regulatory record. The buyer must therefore assess whether the proposed acquisition triggers an open offer, disclosure requirements or other obligations. The analysis can become more complicated where persons acting in concert are involved or where the transaction results in acquisition of control. A listed company acquisition should therefore be reviewed under the current SEBI framework before transaction documents are finalised.
Check foreign investment and FEMA requirements
A cross border acquisition adds another layer of diligence. If a non resident buyer acquires shares in an Indian company, the transaction needs to be assessed under FEMA, the Foreign Exchange Management Non Debt Instruments Rules and related RBI regulations. The RBI’s current framework covers foreign investment, modes of payment and reporting requirements for transfers of equity instruments involving non residents. The buyer should examine the sectoral cap, entry route, pricing rules, reporting requirements and any applicable conditions. The nationality and residence of both buyer and seller can affect the analysis. This makes foreign exchange diligence important before the acquisition agreement is signed, not merely before payment is made.
Review data protection and cybersecurity exposure
Data can be a significant acquisition asset and liability. The target may hold customer information, employee records, financial information, health data or other personal information. The buyer should examine how personal data is collected, used, stored and shared. Contracts with vendors and technology providers should also be reviewed. The Digital Personal Data Protection Act, 2023 establishes India’s statutory framework for processing digital personal data. The Ministry of Electronics and Information Technology has also published the Digital Personal Data Protection Rules, 2025 and an enforcement timeline. A diligence review should therefore consider the target’s data practices and the implications of transferring or continuing to process data after completion. Cybersecurity incidents, data breaches and regulatory communications should also be identified.
Review the company’s insurance coverage
Insurance policies can reveal both protection and exposure. The buyer should review property insurance, professional indemnity, directors and officers insurance, product liability cover, cyber insurance and other material policies. The review should establish policy limits, exclusions, claims history and whether coverage continues after a change of control. A business with significant product liability exposure may require a different insurance structure after acquisition. Insurance should therefore be treated as part of legal and risk diligence rather than merely a financial expense.
How should due diligence findings affect the acquisition agreement?
Finding a legal problem is only the first step. The next question is how the transaction should respond. A minor compliance issue may simply require correction before closing. A material historical tax exposure may require a specific indemnity. A disputed title may become a condition precedent. A major litigation risk may justify an escrow arrangement or price adjustment. The buyer can also seek detailed representations and warranties from the seller. The acquisition agreement should reflect the actual findings from diligence rather than rely on generic protection clauses. This is where corporate lawyers for companies can help translate legal findings into transaction provisions covering conditions precedent, representations, warranties, indemnities, limitations of liability and post closing obligations.
Should the buyer use a share purchase or asset purchase?
The transaction structure can materially change the legal risk profile. In a share purchase, the buyer acquires the shares of the company and the company generally continues to own its existing assets and liabilities. Historical liabilities therefore remain relevant. In an asset purchase, selected assets and liabilities can potentially be transferred according to the agreed structure and applicable law. However, individual asset transfers may require separate consents, registrations, assignments or regulatory approvals. Neither structure eliminates diligence. The appropriate structure depends on the target’s assets, liabilities, tax position, contracts, licences and commercial objectives.
What are the biggest red flags in company acquisition due diligence?
Certain findings deserve immediate attention. Unclear share ownership can affect whether the seller can transfer valid title. A major undisclosed lawsuit can create financial or operational exposure. A key customer contract with a change of control termination right can affect future revenue. Unregistered or improperly assigned intellectual property can reduce the value of the business. Regulatory non compliance can create penalties or threaten licences. Large contingent liabilities can change the economics of the deal. A buyer should also investigate inconsistencies between management statements and statutory records. Such inconsistencies do not necessarily prove wrongdoing, but they warrant further examination.
How does due diligence affect the purchase price?
Due diligence can influence valuation in several ways. A buyer may reduce the purchase price where the target carries material undisclosed risk. Alternatively, the parties may agree to retain the headline price while introducing an escrow or specific indemnity. Some findings may have no effect on price but become conditions before completion. For example, a missing approval may need to be obtained before closing. A disputed share transfer may need to be regularised. A tax filing may need to be corrected. The important point is to connect each legal finding with its commercial consequence.
When should legal due diligence begin?
Legal diligence should begin before the acquisition agreement becomes difficult to change. An NDA and initial information request usually precede detailed diligence. The buyer then establishes a data room and reviews documents according to the risk profile of the target. Early review is useful because major issues can affect valuation and transaction structure. If the buyer discovers a serious issue only after signing, its negotiating position may be weaker. For larger transactions, diligence may continue between signing and completion where conditions precedent remain outstanding.
What happens after legal due diligence is completed?
The diligence exercise should end with a clear risk assessment rather than a large collection of documents. The buyer should understand which issues are resolved, which remain open and which require contractual protection. The acquisition agreement should then reflect these findings. After completion, unresolved matters should be assigned to responsible teams. Some issues may require regulatory filings, contract transfers, employee communications, integration work or post closing remediation. Legal diligence therefore connects directly with transaction execution and post acquisition integration. At this stage, a mergers and acquisitions attorney can assist with translating the diligence findings into the acquisition structure, transaction documents, closing conditions and post completion obligations.
Conclusion
Buying a company without adequate legal diligence can expose the buyer to liabilities which may not be visible from financial statements alone. The legal review should begin with corporate ownership and statutory records. It should then examine contracts, litigation, tax, intellectual property, employment, property, financing, regulatory approvals, data protection and competition law. For listed companies, SEBI requirements require additional attention. For cross border transactions, FEMA and RBI requirements become relevant. For transactions involving substantial market positions, competition law should be assessed before closing. Data protection and labour law also deserve specific attention under India’s evolving regulatory framework.
Most importantly, due diligence should lead to action. A finding should translate into a decision about price, structure, conditions, warranties, indemnities, escrow or remediation. A company may look attractive from the outside. The purpose of legal diligence is to establish what the buyer is actually acquiring before the transaction becomes irreversible.
