How Non-Signatories Get Bound to Arbitration Agreements in India
Why Corporate Structures Complicate Every Arbitration Agreement
An arbitration agreement is only as strong as the parties it can actually bind, so what happens when the company holding the assets never signed one at all?
Most businesses assume that an arbitration agreement only binds the two parties who put pen to paper. In a straightforward transaction between two independent companies, that assumption usually holds. But commercial India rarely works that way anymore. A single project can involve a parent company, a joint venture partner, a special purpose vehicle set up purely to execute one contract, and a handful of group entities that share directors, bank accounts, or even office space.
For years, Indian courts and tribunals wrestled with a simple but stubborn question. If an arbitration agreement is fundamentally a matter of consent, how do you bind an entity that never gave that consent on paper? The early answer was strict and formal. No signature meant no obligation to arbitrate, full stop. Claimants who suspected that a related company was really behind a transaction had to first convince a court, sometimes across multiple hearings and years of preliminary litigation, before the underlying dispute could even begin. That delay was expensive, and it was often enough for a debtor to move assets out of reach entirely. This is starting to change. Indian jurisprudence has steadily built out a set of doctrines that let a court or an arbitral tribunal look past the corporate paperwork and ask a more practical question. The 2025 Supreme Court ruling in ASF Buildtech Pvt. Ltd. v. Shapoorji Pallonji & Co. Pvt. Ltd. (2025 INSC 616), is the latest and clearest confirmation of this shift, and it matters well beyond the facts of that one case, because it reshapes how every arbitration agreement in a layered corporate structure will now be read.
What Makes a Party Bound to an Arbitration Agreement
Indian law now recognises three overlapping routes through which a company that never signed a contract can still be treated as bound by its arbitration agreement. The first and most commonly invoked is the group of companies doctrine. It applies where a company sits within the same corporate family as a signatory and was closely involved in negotiating, performing, or even terminating the underlying agreement. Correspondence, shared decision making, and a consistent pattern of behaving as a single economic unit are usually enough to bring a related entity into the picture. The second route is the alter ego principle. This looks past corporate form altogether. If one company is really just an extension of another, controlled so completely that the two operate as a single entity in substance, a tribunal can treat them as one for the purpose of the arbitration agreement, regardless of who actually signed the arbitration agreement in the first place.
The third is the idea of a composite transaction, which applies when several linked agreements, and every arbitration agreement attached to them, form one commercial arrangement that cannot sensibly be split apart. A works contract, a related supply agreement, and a settlement agreement involving overlapping group entities are a common example. Trying to arbitrate only one strand of that arrangement while leaving the rest in separate proceedings usually produces inconsistent outcomes and wastes everyone's time and money.
What ties all three doctrines together is intent. Indian courts consistently ask whether the non signing entity's own conduct, not just its name on a letterhead, shows that it always understood itself as part of the bargain. A company that negotiated payment terms, issued instructions to contractors, or took responsibility for project delivery has a hard time later claiming it was a stranger to the arbitration agreement.
The Arbitral Tribunal's Growing Authority
For a long time, the power to decide whether a non signatory could be pulled into arbitration, and made subject to an arbitration agreement it never signed, rested mainly with courts, usually at the stage of appointing an arbitrator. That meant a claimant often had to fight a separate legal battle just to establish who the proper parties were, before the actual dispute could even be heard on its merits. The Supreme Court's ruling in ASF Buildtech changed that. The Court confirmed that an arbitral tribunal has the statutory authority under Section 16 of the Arbitration and Conciliation Act, 1996 to decide for itself whether a non signatory should be impleaded, without first needing a court to rule on the question. This power flows from a well established principle in arbitration law that allows a tribunal to rule on its own jurisdiction, including who properly belongs in the proceedings before it.
This case is a meaningful procedural shift. It means a dispute involving a complex corporate structure no longer has to stall for years while courts work out who is a proper party. The arbitral tribunal can resolve that question as part of the same proceeding, keeping the arbitration agreement, and the claim itself, moving forward on a single track

Frequently Asked Questions
Q1. What does it mean for a company to be bound by an arbitration agreement it never signed?
It means a court or an arbitral tribunal has found, based on the company's conduct, that it was genuinely part of the underlying transaction even though it never physically signed the contract. This usually happens through doctrines like the group of companies doctrine, the alter ego principle, or the idea of a composite transaction, all of which look at substance over form rather than at whose signature appears on the page.
a. What is the group of companies doctrine?
It allows a tribunal to bind a company to an arbitration agreement if it belongs to the same corporate group as a signatory and was closely involved in negotiating, performing, or terminating the underlying contract. Shared management, common correspondence, and a consistent pattern of acting as one economic unit are typical evidence used to establish this.
Q2. Can an arbitral tribunal decide this question on its own, without going to court first?
Yes. Following the Supreme Court's 2025 ruling in ASF Buildtech Pvt. Ltd. v. Shapoorji Pallonji & Co. Pvt. Ltd. (2025 INSC 616), an arbitral tribunal has the statutory authority under Section 16 of the Arbitration and Conciliation Act, 1996 to decide for itself whether a non signatory should be impleaded, without waiting for a prior court order on the question.
Q3. How does this affect asset recovery in a commercial dispute?
It allows claimants to bring the entity that actually controls the money or assets into the same arbitration as the entity that signed the contract, instead of winning an award against a company with nothing to pay it with. This closes a common gap that debtors used to exploit by keeping valuable assets inside a related but technically separate entity.
Q4. What is litigation funding and how does it relate to this shift?
Litigation funding is an arrangement where a specialised firm provides the capital needed to pursue a claim in exchange for a share of the eventual settlement or award, usually on a non recourse basis. A clearer path to binding the right non signatory improves a funder's confidence in both the timeline and the likelihood of actual recovery, making complex commercial claims more attractive to fund.
Q5. How can businesses protect themselves when structuring joint ventures or special purpose vehicles?
Businesses should be deliberate about documenting which entity is responsible for which obligation, keep clean records that reflect that responsibility in practice, and consider naming all genuinely involved group entities directly in the arbitration agreement, rather than leaving the question to be resolved later through disputed correspondence.
Q6. How can LegalPay support businesses dealing with complex corporate disputes?
LegalPay helps businesses evaluate and fund high value commercial claims, including those involving joint ventures, group companies, and special purpose vehicles. By helping identify which entities can genuinely be brought into a dispute, LegalPay supports stronger claims and better prospects for recovery without straining a business's own cash flow.
