Best Legal Due Diligence Before You Invest, Buy or Partner Lawyer

Before investing in a company, buying a business, entering a joint venture or purchasing commercial property, you need to know what you are getting. Legal due diligence is a structured review of the target's legal position: who owns it, whether its assets are really its own, what contracts bind it, what disputes it faces, whether it holds the licences it needs, and whether it complies with the law. The findings shape the deal: what you pay, what conditions must be met before closing, what the seller must promise, and sometimes whether to proceed at all.

This page is for investors, acquirers, lenders and partners. In short: agree the scope with your lawyer based on the deal and the target's business; obtain documents from the target through a data room and check public records independently; focus on issues that affect value or the deal's validity, such as title, ownership, material contracts, litigation and licences; receive a report that rates each finding and recommends how to deal with it; and carry the findings into the transaction documents through conditions, warranties, indemnities and price.

Due diligence is not a formality. Most expensive post-deal disputes come from issues that a careful review would have found.

What due diligence covers

Corporate records review

The starting point is the target's corporate records: the certificate of incorporation, memorandum and articles, registers of members and directors, minutes of board and general meetings, and filings with the Registrar of Companies on the MCA portal. The review checks that shares were validly issued and transferred, that the shareholding matches the records, that there are no undisclosed share options or convertible instruments, and that the company's actions were properly authorised.

The MCA portal also shows charges registered against the company's assets, which reveal borrowings and security. Compare the charges with the loan agreements provided, and check that satisfied charges have been released. Gaps in filings, such as unfiled annual returns or allotments not reported, are common in private companies and may need to be regularised before closing.

What the target usually provides

Common red flags

Title due diligence for property

When a deal involves immovable property, whether as the main asset or as part of a business, title due diligence is essential. It traces the chain of title documents for at least 30 years where possible, checks revenue records and mutation entries, obtains encumbrance certificates from the sub-registrar, searches for litigation affecting the property, and confirms that the land use, building approvals and completion or occupancy certificates are in order.

In Delhi NCR, specific issues include leasehold land from authorities such as the DDA, Noida, Greater Noida and YEIDA, where transfer requires the authority's permission and transfer charges; agricultural land restrictions; and unauthorised constructions. In Uttar Pradesh, the land records are available online through the state portal, which helps but does not replace a full search. A title report should state clearly whether the title is clear, what defects exist, and what must be done to cure them.

Litigation searches

Litigation can reduce a target's value or create unexpected liabilities. The target should disclose pending and threatened cases, but independent searches are important. Searches can cover the e-courts system for district courts, High Court and Supreme Court case status systems, NCLT and NCLAT records, DRT records, consumer commission records, and tax authorities' notices where accessible. Searches should cover the target, its directors and promoters, and sometimes key properties.

For each significant case, review the pleadings and orders, assess the likely outcome and exposure, and decide how to deal with it in the deal: price reduction, specific indemnity, escrow, or a condition that the case be resolved before closing.

Laws that apply

How we work

We are a litigation and advisory practice led by Advocate BK Singh, with offices in Dwarka (New Delhi) and Vaishali (Ghaziabad). This is what you can expect:

• Risk focus: findings that matter to value and the deal, not long lists.
• Independent searches: public records checked, not only documents provided.
• Litigation insight: realistic assessment of pending cases.
• Deal integration: findings carried into conditions and warranties.
• Written fee terms: agreed stage by stage, never linked to the outcome.

Mistakes in due diligence

Material contracts

The target's material contracts, such as major customer and supplier agreements, distribution agreements, leases, licences, loan agreements and JV agreements, often determine the value of the business. Review them for term and termination rights, exclusivity, minimum commitments, change-of-control clauses that let the counterparty terminate on a sale, assignment restrictions, liability caps, and dispute clauses.

A change-of-control clause in a key customer contract may mean that the acquisition needs that customer's consent, or risks losing the contract. Loan agreements often require the lender's consent to a change in shareholding. Identify these early, so that consents can be sought before closing.

Licences and regulatory compliance

Many businesses need licences to operate: factory licences, pollution control consents, fire safety certificates, trade licences, food safety licences, drug licences, import-export codes and sector-specific approvals. Check that each licence is current, in the target's name, covers the actual operations and locations, and is transferable or will continue after the deal. Pending renewals or show-cause notices should be flagged.

Environmental compliance can be a significant risk for manufacturing businesses: operating without valid consent to establish or operate under the Water and Air Acts, improper hazardous waste handling, or groundwater extraction without permission can lead to closure orders and penalties. See our network site on environmental law for detail.

Employment and labour

Review employment contracts for key staff, including notice periods, non-compete and confidentiality terms; the target's compliance with labour laws, including provident fund, employee state insurance, gratuity and minimum wages; contract labour arrangements; and any pending labour disputes. With the labour codes in force from November 2025, check whether the target has updated its practices.

ESOPs and other incentive plans should be reviewed for what happens to options on a change of control. Retention of key employees after the deal may need new arrangements, which should be planned before closing.

Intellectual property

For technology and consumer businesses, IP is often the most valuable asset. Check trademark registrations and applications, their owner, classes and status; copyright in software and content, and whether employees and contractors have assigned their work to the company; patents and designs where relevant; and domain names. A common finding in startups is that the brand or the code is owned by a founder personally, or by an agency that was never asked to assign it.

Also check licences in and out: software licences the business relies on, open-source components and their licence terms, and any licences the business has granted to others.

Tax and financial issues

Legal due diligence usually works alongside financial and tax due diligence by chartered accountants. The legal team reviews tax disputes and notices from a litigation perspective, and coordinates on issues such as stamp duty on past share transfers, GST disputes, and income tax demands. Contingent liabilities shown in the financial statements should be matched with the litigation findings.

Where financial due diligence shows related-party transactions, the legal team checks whether they were properly approved under the Companies Act. Where it shows large receivables, the legal team may assess their recoverability and the contracts behind them.

From findings to deal terms

A due diligence report is useful only if it changes the deal. For each significant finding, decide whether it should be fixed before closing (a condition precedent), covered by a specific indemnity, secured by an escrow or holdback, reflected in a price reduction, or accepted as a risk. General warranties in the share purchase agreement cover unknown risks, but known issues should be dealt with specifically, since a buyer who knew of a problem may find it hard to claim under a general warranty.

Disclosure letters from the seller, setting out exceptions to the warranties, should be reviewed against the diligence findings. See mergers and acquisitions.

Due diligence for lenders

Lenders and financiers conduct legal due diligence before taking security over a borrower's assets. The focus is on the title to the property offered as security, existing charges and encumbrances, the borrower's capacity and authorisation to borrow and create security, and any litigation that could affect the security. A title search report and a search on the MCA portal for existing charges are standard.

For loans against property in Delhi NCR, check authority leases, permissions for mortgage, and whether the property is free from litigation and attachment. For loans to companies, check the articles for borrowing limits and the board and shareholder approvals under Section 180 where required.

Vendor due diligence

Sellers increasingly commission due diligence on their own business before approaching buyers. Vendor due diligence identifies problems that can be fixed before the sale, such as missing filings, title defects or unassigned IP, and prepares a clean data room. It speeds up the buyer's review, reduces the scope for price reductions, and gives the seller more control over how issues are presented.

Even where a full vendor report is not prepared, a seller should organise its key documents, regularise obvious gaps, and prepare a list of known issues with explanations before inviting buyers.

Startup due diligence for investors

For early-stage investments, due diligence is usually lighter but should still cover the essentials: the company's incorporation and cap table, founders' agreement and vesting, IP ownership and assignments, key customer contracts, employment and ESOP documents, compliance with FEMA for any earlier foreign investment, and any disputes. Investors often use a standard questionnaire and a short report focused on these areas.

The most common findings in startup diligence are IP owned by founders or freelancers, informal promises of equity to early employees, missing filings for earlier allotments, and founders without vesting. Each can usually be fixed before closing.

Data protection in due diligence

Due diligence often involves reviewing documents that contain personal data, such as employee records and customer lists. Under the Digital Personal Data Protection Act, 2023, as its rules apply, the target must have a lawful basis to share such data, and the buyer must protect it. Use a confidentiality agreement, limit access to those who need it, redact personal data where possible, and agree how data will be returned or deleted if the deal does not proceed.
