Investing in Indian Start-ups From the UK: A Legal Due Diligence Checklist

British angels, family offices and venture funds are increasingly looking at India, the world’s third-largest start-up ecosystem, and the UK-India trade deal has added fresh momentum. But investing in Indian start-ups from the UK involves legal risks that don’t show up in a pitch deck.

This checklist explains the legal due diligence UK investors should carry out on Indian start-ups: corporate records and cap tables, foreign investment compliance, intellectual property, data protection, tax, labour and regulatory issues, and the protections to build into the deal. UK tax and regulatory points should be checked with UK advisers. For the US-facing version, see our legal due diligence checklist for US investors.

Corporate records, cap table and founders

Start with the public record. Indian companies file their key documents with the Ministry of Corporate Affairs: incorporation documents, articles of association, share allotments, director appointments, charges and annual returns. Compare these filings with the cap table the start-up shows you, because gaps between the two are a common red flag.

Check the ESOP scheme. Under Indian company law, an ESOP scheme needs a special resolution of shareholders and must meet specific rules, including a minimum one-year vesting period. Options granted without a valid scheme can lead to disputes and unexpected dilution; see our guide to ESOPs for Indian startups. Review convertible instruments too: convertible notes, compulsorily convertible preference shares and debentures, and the terms of earlier rounds; see our guide to SAFE and convertible notes in India.

UK investors should also read the shareholders’ agreements and articles from earlier rounds closely. Existing investors’ vetoes, anti-dilution protections, liquidation preferences and information rights shape what a new investor can negotiate, and Indian start-ups sometimes have side letters that aren’t reflected in the main documents. Look closely at the founders. Is there a founders’ agreement with vesting and IP assignment? Are transfer restrictions reflected in the articles, which Indian courts have long required for them to bind the company? Are key assets such as domain names, trade marks or code repositories held by a founder personally? See our guide to founders’ agreements in India.

Foreign investment and FEMA compliance

For UK investors, foreign exchange compliance is the area most often overlooked when investing in Indian start-ups. Every past foreign investment into the company should have been priced in line with Indian rules and reported to the RBI, for example on Form FC-GPR within 30 days of allotment. Missing or late filings must be regularised before you invest, because your investment depends on the same compliance chain.

Your own investment must follow the same rules. Shares issued to a UK investor must be priced at or above fair value, supported by a valuation report, and the company must report the investment. Most technology sectors allow 100% foreign investment under the automatic route, but some sectors have caps or require approval.

UK funds structuring their own vehicles should also consider whether to invest directly or through an intermediate holding company, which affects tax under the India-UK treaty, exit options and reporting. Check the investor base for Press Note 3 issues. Investment from countries sharing a land border with India requires government approval, and a UK fund with limited partners or beneficial owners from such countries may need to consider this. If the start-up has a foreign holding company, or founders hold shares in offshore entities, review overseas investment compliance as well; see our guide to reverse flips from Delaware to India.

IP, data protection, tax and labour

Intellectual property is often the core asset, so confirm the chain of title. Under India’s Copyright Act, employees’ work in the course of employment generally belongs to the employer, but freelancers and agencies own their work unless they assign it in writing, and Section 19 imposes specific formal requirements; see our guide to IP assignment for UK start-ups with Indian developers. Review employment and contractor agreements, Indian and international trade mark registrations, and any patents; see our guide to protecting a UK trade mark in India.

Check data protection readiness. India’s Digital Personal Data Protection Act, 2023 applies its main obligations from 13 May 2027, with penalties of up to ₹250 crore for security failures. A consumer start-up with weak data practices today carries real future risk. Look also at compliance with CERT-In’s cyber incident directions; see our guide to the CERT-In 6-hour rule.

Review tax and labour. Look at GST and withholding compliance, tax disputes, and any reliance on start-up tax incentives that require specific certification; see our guide to the Income-tax Act 2025 for startups. Check compliance with India’s four labour codes, in force since 21 November 2025, including salary structures, social security and the treatment of contractors and gig workers; see our guide to the new labour codes for startups.

Litigation, licences and sector risks

Search for litigation in Indian courts, tribunals and consumer forums, including insolvency proceedings before the NCLT and any criminal complaints involving the company or founders. Indian court records are increasingly searchable online, but coverage varies, so combine searches with management disclosures and warranties.

Confirm the licences and registrations the business needs. Fintech start-ups may need RBI authorisations or must work through regulated partners. Crypto businesses must register with FIU-IND under India’s anti-money laundering law; see our guide to FIU-IND registration. Online gaming businesses face India’s 2025 ban on online money games; see the Online Gaming Act 2025. Healthcare, education and food businesses each have their own regulators.

Investing in Indian start-ups also means understanding exit routes: Indian IPOs, secondary sales, buybacks and strategic acquisitions each have their own regulatory and tax rules, including FEMA pricing rules for transfers between residents and non-residents. Finally, consider regulatory trends that could affect the business model, such as consumer protection rules on dark patterns, data protection, platform regulation and sector-specific changes. These often matter more than past compliance.

Protecting UK investors in the deal, and quick answers

Due diligence findings should shape the investment documents. Use conditions precedent to require fixes before completion, such as regularising FEMA filings, executing IP assignments or properly approving ESOP schemes. Negotiate warranties and specific indemnities for known risks, and consider escrow or holdbacks for larger issues.

On enforcement, UK investors are in a stronger position than many others: India enforces arbitral awards from New York Convention countries, and the UK is a reciprocating territory under Section 44A of India’s Code of Civil Procedure, so certain UK superior court judgments can be executed in India. Confirm that the UK remains on the Section 44A list. Even so, arbitration seated in London, Singapore or India is often the preferred route. UK tax reliefs for investors, such as SEIS and EIS, generally have conditions that overseas companies may not meet, so take UK tax advice before relying on them. For the UK-India market context, see our trade deal checklist. Careful due diligence is what makes investing in Indian start-ups from the UK a sound decision.

What is the biggest legal risk when investing in Indian start-ups?

Foreign exchange compliance gaps, such as unreported or mispriced foreign investment, are among the most common and must be fixed before completion.

Certain UK superior court judgments can be executed in India because the UK is a reciprocating territory under Section 44A of the Code of Civil Procedure.

Usually not in sectors under the automatic route, but pricing, reporting and Press Note 3 rules must be followed.
