Share Purchase Agreement Drafting in India: Close a Clean Buy-In or Buy-Out
Whenever shares in a private company change hands - an investor buying in, a co-founder buying out an exiting partner, or a full acquisition - the transaction needs a Share Purchase Agreement (SPA) to be legally sound and enforceable. Without one, disputes over price, representations, or post-sale liabilities are far harder to resolve. This guide explains what an SPA must cover and how KanoonPe drafts one for full or partial stake sales.

What is a Share Purchase Agreement?
A Share Purchase Agreement (SPA) is a contract between a seller and a buyer that governs the sale and transfer of shares in a company, including the price, conditions, representations, and post-closing obligations. It is enforceable under the Indian Contract Act, 1872, and the actual transfer of shares is executed under Section 56 of the Companies Act, 2013, using Form SH-4.
An SPA is used both when an outside investor buys newly acquired or existing shares, and when one shareholder buys out another - whether that is a full acquisition of the company or a partial stake sale.
Types of Share Purchase Agreements
- Full sale / acquisition SPA - covers a complete change of ownership, where the buyer acquires all or a controlling majority of the company's shares, typically with extensive representations, warranties, and indemnities.
- Partial stake sale SPA - covers the sale of a minority or specific percentage stake, common in angel/VC investment rounds or when one co-founder buys out another's shares without a full company sale.
- Secondary sale SPA - shares are purchased from an existing shareholder rather than newly issued by the company, distinct from a primary share subscription.
Key clauses a Share Purchase Agreement should contain
- Parties and shares being sold - seller, buyer, number of shares, and class (equity/preference).
- Purchase price and payment mechanism - consideration, valuation basis, and payment schedule or escrow arrangement.
- Conditions precedent - approvals, consents, or due diligence items that must be completed before closing.
- Representations and warranties - seller confirms facts about the company (no undisclosed liabilities, clean title to shares, compliance status).
- Indemnity clause - allocates responsibility for losses arising from breach of representations after closing.
- Non-compete and non-solicit - restricts the seller from competing with or poaching from the company post-sale.
- Closing mechanics - what documents (Form SH-4, share certificates, board resolutions) are exchanged at completion.
- Governing law and dispute resolution - jurisdiction and arbitration mechanism for disputes.
Who should use a Share Purchase Agreement
- Investors buying equity in a private company through a primary or secondary transaction.
- Founders or shareholders selling their stake, partially or fully, to a co-founder, investor, or third party.
- Companies undergoing acquisition where an external buyer purchases a controlling stake.
- Employees exercising ESOPs who need a transfer document when converting or selling vested shares.

Drafting and delivery process
- Share your requirements. Provide the transaction details - parties, shares, price, and any negotiated conditions.
- Lawyer drafts the SPA. A corporate lawyer prepares a draft covering price, representations, warranties, and closing mechanics.
- Review and revisions. Both parties review the draft; two rounds of revisions are included to finalise commercial terms.
- Finalisation and Form SH-4. The final SPA is shared for signature, along with the Form SH-4 share transfer instrument for execution.
- Stamping and register update. The transfer instrument is stamped, and the company updates its register of members to reflect the new shareholder.

Stamping and registration notes
Stamp duty is payable on the share transfer instrument under the Indian Stamp Act, 1899, and applicable state stamp legislation - under the current amended framework this is generally around 0.25% of the transaction consideration, though the exact rate can vary depending on the instrument and state, so it's worth confirming for your specific transaction. The SPA itself does not need to be registered with the Registrar of Companies. However, the actual transfer of shares must be executed using Form SH-4 under Section 56 of the Companies Act, 2013, and the company must update its register of members to reflect the new shareholding - this step is what makes the transfer legally effective against the company.
Common mistakes and risks
- Skipping Form SH-4 - signing only the SPA without executing the SH-4 transfer instrument leaves the transfer legally incomplete.
- Weak representations and warranties - vague or missing warranties expose the buyer to undisclosed liabilities after closing.
- No indemnity clause - without one, the buyer has limited recourse if the seller's representations turn out to be false.
- Underpaying stamp duty - using an incorrect consideration value to reduce stamp duty can render the instrument inadmissible as evidence.
- Not updating the register of members - the transfer isn't effective against the company until this internal record is updated.
