Co-founder disputes in Indian startups: legal options, buyout mechanics & SHA

When a co-founder dispute surfaces in an Indian startup, the outcome is rarely decided in a boardroom or a court. It is decided by whatever was written into the shareholders’ agreement six months or two years before the relationship broke down. Founders who go into a dispute with a well-drafted SHA have leverage, a clear path, and a predictable timeline. Founders who go in with a generic template or nothing at all find themselves in a valuation fight, a Section 241 petition, or an injunction that freezes a funding round. The pattern across hundreds of founder transactions is consistent: the documents written at incorporation determine the cost of every conflict that follows.

What actually triggers a co-founder dispute: legal event, not a people problem

Four patterns account for the majority of co-founder disputes Treelife sees in live mandates. None of them start as legal problems. All of them become legal problems.

• The undocumented sweat equity claim – A founder contributes product, early sales, or operational work on the basis of a verbal promise. The paperwork, if any, shows a consulting agreement. When the company converts or raises a round, the equity is not there. The verbal promise is now a shadow equity claim under contract law. Courts will examine email chains, WhatsApp messages, and any written communication that suggests a promise was made. If the equity was not explicitly ruled out in writing, the claim survives.
• The dormant cap table – Multiple early contributors were added with an equal-split handshake. One went passive, another moved abroad. When a Series A term sheet arrives, those names are still on the register. They have not signed any vesting schedule. They have pre-emptive rights and anti-dilution protection. What looked like a 25% stake now creates a 50% problem.
• The unassigned IP – An early product was built with a friend’s agency or a freelancer who never invoiced. No IP assignment agreement was signed. The company is now in acquisition due diligence and the acquirer’s lawyers have found the gap. The friend wants advisory equity. The acquirer wants representations. The founders have neither.
• The misaligned exit – One founder begins exploring an acquisition. The other finds out from a LinkedIn post. The second founder is not aligned on valuation, future role, or deal structure. The acquirer walks. The relationship ends. A Section 241 petition under the Companies Act, 2013 is filed alleging oppression.

Each of these is preventable. Each becomes expensive once the dispute is live because the legal system then fills in whatever the SHA left blank, usually in ways neither party wanted.

The SHA clauses that determine your position before any dispute is filed

This is where founders systematically underinvest. Most SHA templates circulating in the Indian startup ecosystem cover equity split and anti-dilution. They leave the dispute-critical clauses either vague or absent. The table below maps what each clause does and what happens when it is missing.

Table 1: SHA clauses and their dispute impact

SHA clause	What it does	If the SHA is silent
Vesting schedule with cliff	Equity accrues over time (typically 4 years, 1-year cliff). Unvested shares revert to the company on exit.	Exiting founder retains full equity regardless of contribution. Company cannot dilute without their consent.
Exit valuation formula	Specifies how buyout price is calculated (DCF, book value, independent CA, multiple of revenue).	Valuation fight defaults to Rule 11UA under Income Tax Rules 1962, which may not reflect company reality.
Deadlock resolution mechanism	Defines what happens when founders cannot agree on a reserved matter (Russian roulette clause, casting vote, or third-party decision-maker).	No mechanism exists. Company is paralysed. NCLT intervention or dissolution becomes the only path.
Drag-along rights	Majority shareholder can compel minority to sell in an acquisition on the same terms.	Minority co-founder can block or delay any M&A transaction.
Tag-along rights	Minority shareholder can participate in any sale on the same terms as majority.	Minority is exposed to being left behind in a secondary sale.
IP assignment clause	All IP created by founders is assigned to the company at incorporation.	IP ownership sits with the individual founder. Acquirers flag this as a deal-breaker in due diligence.
Non-compete scope	Defines geography, duration, and activity restriction post-exit.	Exiting co-founder can immediately join or build a competitor. Enforcement under Section 27, Indian Contract Act 1872 is contested (see below).
Forced transfer trigger	Specifies events that require a founder to sell their shares (misconduct, breach, prolonged absence).	Removing a non-performing or hostile co-founder requires NCLT petition or negotiated agreement, both of which are slow and costly.

One point on non-compete clauses specifically: Section 27 of the Indian Contract Act, 1872 renders agreements in restraint of trade void. Indian courts have taken varying positions on whether post-exit non-competes in founder agreements are enforceable. The safer approach is to anchor the restriction to protection of confidential information and trade secrets rather than a blanket prohibition on competing activity. Treelife recommends pairing the non-compete with a robust confidentiality clause and an IP assignment clause, which together achieve the commercial objective without the Section 27 vulnerability.

How does a co-founder buyout actually get priced in India?

Valuation is where most co-founder buyouts collapse. The SHA said “fair market value” without defining it. Now two founders with opposing interests are arguing about what the company is worth.

Indian law provides a default mechanism: Rule 11UA of the Income Tax Rules, 1962. This rule prescribes the methods for determining fair market value of unquoted equity shares for the purposes of the Income Tax Act, 1961. The two primary methods under Rule 11UA are the net asset value (NAV) method and the discounted cash flow (DCF) method. For a pre-revenue or early-stage startup, NAV typically produces a lower number than DCF. For a profitable company, the gap can be reversed.

The problem is that Rule 11UA was designed for tax compliance, not for equitable buyout pricing between founders. An early-stage SaaS startup with Rs. 2 crore in ARR and Rs. 50 lakh in net assets will produce a vastly different valuation under NAV vs DCF, and a departing co-founder will instinctively gravitate toward whichever produces the higher number.

Rule 11UA, Income Tax Rules, 1962 governs fair market value determination for unquoted equity share transfers. For transfers between resident co-founders, the applicable methods are NAV and DCF. The angel tax provision under Section 56(2)(viib) of the Income Tax Act, 1961, which had historically driven Rule 11UA scrutiny for startup share issuances, was abolished with effect from 01/04/2025 by the Finance (No. 2) Act, 2024. It is no longer relevant to domestic co-founder transactions. Where either party to the transfer is a non-resident, five additional valuation methods apply under the CBDT Notification No. 81/2023 amendment to Rule 11UA (Comparable Company Multiple, PWERM, Option Pricing, Milestone Analysis, Replacement Cost), and a Category I Merchant Banker must typically certify the valuation.

What should the SHA say on valuation?

Three approaches, in order of robustness:

Option 1: Independent valuer with defined methodology. Specify that valuation shall be conducted by a Category I Merchant Banker or a Chartered Accountant registered under the ICAI, using a named methodology (typically DCF for growth-stage, NAV for early-stage), with a defined timeline (say, 30 days from the trigger event) and cost split between the parties.

Option 2: Formula-based valuation. For businesses with predictable revenue, specify a revenue multiple or EBITDA multiple as the floor, with DCF as the ceiling. This narrows the range of the valuation fight even if it does not eliminate it.

Option 3: Russian roulette or shotgun clause. One founder names a price. The other founder must either buy at that price or sell at that price. This is blunt but efficient. It incentivises the offering founder to name a fair price because they do not know which side of the transaction they will end up on. Courts in India have upheld Russian roulette clauses where they were clearly drafted and the parties had legal representation at the time of execution.

If the SHA is silent on valuation, and the parties cannot agree, the default legal outcome is either a negotiated settlement under threat of NCLT, or an independent expert appointed by the NCLT under Section 242, Companies Act, 2013. Both are slower and more expensive than any contractual mechanism.

Which legal path fits your situation?

Not every co-founder dispute requires litigation. Not every dispute can be resolved without it. The table below maps the four available paths against the scenarios where each is appropriate.

Table 2: Legal paths for co-founder disputes in India

Path	What triggers it	Realistic timeline	What it achieves	What it cannot do
Negotiated exit	Both parties willing to talk	4-12 weeks	Clean separation, agreed price, confidential	Does not work if one party is hostile or using delay as leverage
Arbitration (Arbitration and Conciliation Act, 1996)	Arbitration clause in SHA	6-18 months (institutional); 12-36 months (ad hoc)	Binding award, confidential, enforceable	Cannot grant company law remedies (directorship removal, share allotment disputes)
NCLT petition under Section 241/242, Companies Act, 2013	Oppression or mismanagement by majority	12-36 months	Can order share buyback, reconstitute board, wind up company	Requires genuine oppression threshold; cannot be used for simple disagreements
Section 9 interim injunction (Arbitration Act, 1996)	Imminent irreparable harm during arbitration	2-6 weeks for hearing	Freezes a transaction, preserves status quo	Temporary only; requires strong prima facie case

When does a Section 241 petition actually work?

Section 241 of the Companies Act, 2013 allows a member holding at least 10% of the issued share capital (or such lower percentage as the Central Government may prescribe for small companies) to petition the National Company Law Tribunal (NCLT) on grounds of oppression or mismanagement. Where a founder has been diluted below 10% through subsequent funding rounds, the NCLT retains discretion to waive this threshold under Section 244(2) of the Companies Act, 2013 in exceptional circumstances, as established in the Cyrus Investments/Tata Sons line of precedent. The threshold is therefore a starting point, not an absolute bar, for a genuinely aggrieved minority founder. The threshold for oppression itself is not merely disagreement. Courts and the NCLT look for conduct that is burdensome, harsh, and wrongful: unfair dilution without consent, exclusion from board decisions, diversion of company funds, or removal of a director without following due process under Section 169 of the Companies Act, 2013.

Founders who file Section 241 petitions as a tactical move to delay a fundraise or acquisition typically find that the NCLT examines whether the petitioner’s own conduct was clean. A co-founder who stopped attending board meetings, stopped meeting vesting milestones, or who has competing business interests will face a harder case before the NCLT regardless of how the majority treated them.

When is a Section 9 injunction the right move?

If a hostile co-founder is about to execute a share transfer, sign a contract on behalf of the company without authorisation, or participate in an M&A transaction that you believe violates your SHA rights, a Section 9 application under the Arbitration and Conciliation Act, 1996 can seek interim relief from the competent court within days. The court will consider whether there is a prima facie case, whether the balance of convenience favours the applicant, and whether irreparable harm would result without the injunction.

The practical risk: if you are the target of a Section 9 application and the court grants the injunction, your M&A transaction is frozen. Acquirers in India increasingly walk away from transactions where founder litigation risk surfaces mid-process. Use this path judiciously.

What changes if your entity is an LLP, not a Pvt Ltd?

Most startup dispute content assumes a private limited company structure. A meaningful number of early-stage ventures and professional services startups are LLPs. The legal framework is different.

Under the Limited Liability Partnership Act, 2008, partner exits and disputes are governed primarily by the LLP agreement. The NCLT has jurisdiction over LLP disputes under certain provisions, but the oppression and mismanagement framework under Sections 241/242 of the Companies Act, 2013 does not directly apply to LLPs. Dissolution of an LLP can be ordered by the tribunal under Section 64 of the LLP Act, 2008 on grounds including just and equitable winding up.

Arbitration remains available and effective for LLPs, provided the LLP agreement includes an arbitration clause. Statutory filings on partner changes are made via Form 4 with the Registrar of Companies (as opposed to Form DIR-12 and Form SH-4 for Pvt Ltds).

If your startup is structured as an LLP and a co-founder dispute is developing, the resolution path is faster but the statutory protection is narrower. Converting to a Pvt Ltd before a dispute escalates is worth considering, though it requires compliance under the Companies Act, 2013 and MCA approval.

The tax consequences nobody warns you about

A co-founder buyout is, in tax terms, a share transfer. The tax treatment depends on the structure of the transaction.

Capital gains on share transfer. When the exiting co-founder sells their unlisted startup shares, the gain is taxed as capital gains. Unlisted shares qualify as long-term capital assets if held for more than 24 months. Long-term capital gain on unlisted shares is taxed at 12.5% without indexation under Section 112 of the Income Tax Act, 1961, following the revision introduced by the Finance (No. 2) Act, 2024 with effect from 23/07/2024. The earlier 20% with indexation option under Section 112 no longer applies to transfers after that date. Section 112A, which carries a 12.5% concessional rate, applies only to listed equity shares, equity-oriented mutual funds, and business trust units where Securities Transaction Tax has been paid. It does not apply to unlisted startup shares. Short-term capital gain on shares held under 24 months is taxed at the applicable slab rate. For a founder who has held shares since incorporation and is exiting at a later-stage valuation, this liability can be significant and must be modelled before agreeing on a buyout price.

Company buyback. If the company buys back the exiting founder’s shares rather than another founder purchasing them, the tax position changed materially from 01/10/2024. Section 115QA of the Income Tax Act, 1961 (which previously required the company to pay buyback distribution tax at an effective rate of 23.296%) no longer applies to buybacks executed on or after 01/10/2024. Under the Finance (No. 2) Act, 2024, buyback proceeds are now treated as deemed dividend under the newly inserted Section 2(22)(f) of the Income Tax Act, 1961, and taxed in the hands of the shareholder as income from other sources at applicable slab rates. No deduction is permitted for the cost of acquiring the shares. The shareholder records a capital loss (cost of shares less nil deemed consideration) which can only be set off against other capital gains, not against income. For a founder in the 30% tax bracket, this treatment is materially more expensive than the pre-October 2024 regime. The company is required to deduct TDS at 10% for resident shareholders at the time of buyback. Always model this tax consequence before choosing a buyback structure over a peer-to-peer share transfer.

ESOP-holding co-founders. If the exiting co-founder holds ESOPs rather than directly allotted shares, the tax event occurs at two points: perquisite tax at the time of exercise (as salary income under Section 17(2) of the Income Tax Act, 1961) and capital gains tax on eventual sale. Unvested options generally lapse on exit as per the company’s ESOP plan. The SHA should cross-reference the ESOP plan on this point to avoid a separate dispute.

GST. Share transfers between residents are generally not subject to GST. Monetary settlements characterised as service fees or consultancy payments may attract GST. Structure matters here.

Common mistakes that cost founders the most in a dispute

Treating the founders’ agreement as a formality at incorporation. The SHA is signed under time pressure, usually in the week of incorporation or the week before a first investor meeting. The valuation clause says “fair market value,” the exit clause says “as mutually agreed,” and the IP assignment is in a separate document that nobody follows up on. These gaps cost nothing at signing and everything in a dispute.

Letting equity sit on the cap table without vesting. A co-founder who is no longer active in the business but holds 20-25% without any cap table vesting mechanism has no legal obligation to sell, no reason to approve dilution, and every incentive to hold out for a premium. A four-year vesting schedule with a one-year cliff, drafted at inception, would have addressed this entirely.

Filing NCLT as a first move. Section 241 is a blunt instrument. It is public, slow, and signals to every investor and acquirer that the company’s governance is under judicial scrutiny. Founders who use it as leverage before attempting negotiation or mediation typically find that the process costs more than the dispute itself was worth, and that the company’s valuation suffers in the interim.

Ignoring the tax structure of the buyout. Two founders agree on an exit price of Rs. 5 crore. Nobody has modelled the capital gains liability, the buyback tax if the company is the buyer, or the GST on any advisory fee payment. The exiting founder discovers post-signing that Rs. 1.2 crore of the Rs. 5 crore goes to tax. The deal sours and sometimes unravels.

Not notifying investors before the exit is executed. Most SHA templates include an investor information right or a consent right for co-founder exits above a certain share threshold. Executing an exit without investor notification is a breach of the SHA. Investors who find out post-facto may invoke other SHA rights or withhold further tranches.

Treelife practitioner note

In the SHA and dispute mandates we have handled at Treelife, the most consistent pattern is not the absence of an agreement. It is the presence of a generic agreement that was never stress-tested against the actual founder relationship.

We routinely see SHA templates that have four-year vesting and a one-year cliff but define “cause” for accelerated vesting so broadly that it is unenforceable. We see deadlock clauses that specify mediation, then arbitration, then “as the board may decide”, without specifying who decides when the board itself is deadlocked. We see IP assignment clauses that cover future IP but not IP already built before incorporation, which is precisely where the dispute starts.

The exercise we run for every founder client before any dispute surfaces is a scenario stress test: we take the SHA and run three hypotheticals through it: one founder resigns, one founder is asked to leave, an acquisition offer comes in at 5x. In most cases, the agreement is silent on at least one critical point in each scenario. The cost of fixing this before a dispute is a few hours of legal review. The cost of addressing it after a dispute is typically a multiple of the company’s last-round valuation in legal fees, delay, and lost deals.

The SHA is not the document that starts a company. It is the document that determines what happens when the company starts becoming valuable, or starts falling apart. Those two events often arrive closer together than founders expect.

Case study

Situation: Series A SaaS startup, Bengaluru. Three co-founders held equal equity with no vesting schedule. One founder became passive after a personal health issue eighteen months post-incorporation.

Challenge: Active founders wanted to dilute passive founder’s stake before the Series A close. Passive founder refused consent. Investor term sheet had a 60-day exclusivity window. No deadlock mechanism in SHA.

What Treelife did: Negotiated a buyout structure using an independent CA valuation under Rule 11UA, drafted an exit agreement with a 24-month non-compete anchored to confidentiality obligations rather than a blanket trade restraint, and structured the consideration as a staggered payment tied to the Series A close to manage cash flow.

Outcome: Exit executed in 38 days. Series A closed within the exclusivity window. Passive founder received a price 1.4x the Rule 11UA NAV figure. No litigation.

FAQs on Co-Founder Disputes in India

Q: Can a co-founder be removed without their consent in India?
A: Not unilaterally, unless the SHA has a forced transfer trigger clause and the triggering event has occurred. A director can be removed by ordinary resolution under Section 169 of the Companies Act, 2013 with special notice, but removal as a director does not affect share ownership. Equity can only be compulsorily transferred if the SHA expressly provides for it and the prescribed process is followed. Without such a clause, the company must negotiate a buyout or petition the NCLT.

Q: Is a verbal promise of equity enforceable in India?
A: Verbal agreements are technically contracts under the Indian Contract Act, 1872. The difficulty is proof. Courts will examine email threads, WhatsApp messages, meeting minutes, and any written communication that corroborates the oral promise. A verbal promise is not automatically unenforceable, but it is substantially harder to establish and the outcome is uncertain. Get any equity arrangement into writing, even an informal MoU, before work begins.

Q: What happens to unvested equity when a co-founder exits?
A: Under a properly drafted vesting schedule, unvested shares revert to the company upon exit. The SHA should specify whether reversion is at face value or at nil consideration, and the mechanism for the actual share transfer back. If the SHA is silent, unvested equity technically remains with the exiting founder absent a specific contractual provision requiring return.

Q: Can I file a Section 241 petition just to freeze a deal I disagree with?
A: Section 241 of the Companies Act, 2013 requires genuine oppression or mismanagement, not mere disagreement on strategy. The NCLT has consistently held that the petitioner must demonstrate conduct that is burdensome, harsh, and wrongful. Using it purely as a tactical delay mechanism is likely to fail and may expose the petitioner to costs. A Section 9 injunction under the Arbitration Act is a faster and more targeted tool if the issue is a specific pending transaction.

Q: How long does an NCLT co-founder dispute take to resolve?
A: NCLT timelines in practice range from 18 months to 36 months for a contested petition, though interim relief (such as staying a share transfer or board decision) can be obtained within weeks of filing. The National Company Law Appellate Tribunal (NCLAT) adds further time if a party appeals. Arbitration, by contrast, typically runs 12-24 months for institutional arbitration under the ICADR or DIAC rules.

Q: What is the tax on a co-founder buyout?
A: If the exiting co-founder sells unlisted startup shares held for more than 24 months, the gain is taxed as long-term capital gain at 12.5% without indexation under Section 112 of the Income Tax Act, 1961 (revised rate from 23/07/2024). Section 112A does not apply to unlisted shares. Short-term gains on shares held under 24 months are taxed at slab rate. If the company buys back shares rather than a peer transfer, buyback proceeds are treated as deemed dividend under Section 2(22)(f) and taxed at the shareholder’s slab rate, with no deduction for cost of acquisition permitted (effective from 01/10/2024). Always model the tax before agreeing on a buyout price and structure.

Q: Does arbitration work for co-founder disputes in India?
A: Yes, provided the SHA includes a clear arbitration clause specifying the seat, the rules (ICADR, DIAC, or ICC), the number of arbitrators, and the governing law. Indian courts have consistently upheld arbitration clauses in shareholder agreements and will refer parties to arbitration when one party attempts to litigate in civil court. The advantage of arbitration is confidentiality and speed relative to litigation. The limitation is that arbitration cannot grant company law-specific remedies such as directorship reconstitution or compulsory share buyback; those require NCLT.

Q: Can a Section 9 injunction stop a funding round or acquisition?
A: Yes. A Section 9 application under the Arbitration and Conciliation Act, 1996 can seek a stay on share transfers, execution of agreements, or any transaction that would cause irreparable harm to the applicant pending arbitration. Courts have granted such injunctions to freeze M&A processes where a founder established a prima facie case of SHA violation. The risk to the company is significant: acquirers and investors routinely exit processes where founder litigation is visible.

Q: What is a Russian roulette clause and is it enforceable in India?
A: A Russian roulette or shotgun clause requires one founder to name a share price, after which the other founder must either buy at that price or sell at that price. It is an effective deadlock breaker because it incentivises fair pricing. Indian courts have upheld Russian roulette clauses where they were clearly drafted and the parties had independent legal representation at execution. The clause should specify the timeline for exercising the option, the payment mechanism, and what happens if neither party has the liquidity to buy.

Q: What filings are required when a co-founder exits a Pvt Ltd?
A: For a director resignation, Form DIR-12 must be filed with the Registrar of Companies within 30 days of the date of cessation. For share transfer, Form SH-4 (share transfer deed) must be executed and the company’s register of members updated. Annual filings (MGT-7 and AOC-4) must reflect the updated shareholding. Failure to file within prescribed timelines attracts penalties under the Companies Act, 2013.

Q: Does FEMA apply to a co-founder buyout where one founder is an NRI or foreign national?
A: Yes. If either party to the share transfer is a non-resident Indian or a foreign national, the transaction is subject to FEMA 1999 and the Foreign Exchange Management (Non-Debt Instruments) Rules, 2019. Pricing must comply with the prescribed valuation norms for foreign investment transactions. The AD (Authorised Dealer) bank must be involved in the remittance. Failure to comply with FEMA can result in penalties of up to three times the amount involved under Section 13 of FEMA 1999.

Q: Can the company be wound up because of a co-founder dispute?
A: Yes, in extreme cases. The NCLT can order winding up on “just and equitable” grounds under Section 271(e) of the Companies Act, 2013 if the company’s substratum has disappeared or if the relationship between founders has broken down to the point where the company cannot be managed. Courts treat this as a last resort. In most cases where winding up is threatened, the NCLT instead orders a buyout of the petitioner’s shares at fair value under Section 242.

Q: How does a co-founder dispute affect an ongoing fundraise?
A: Immediately and materially. Investors conduct diligence on the founding team as rigorously as on the business. Any pending litigation, NCLT petition, or unresolved equity claim on the cap table will surface in diligence. Most institutional investors will not proceed to term sheet execution until the dispute is resolved or ring-fenced. A Section 9 injunction on the company’s shares can make a fundraise legally impossible until the stay is vacated.
