Supreme Court Joins Non-Signatory Partners to Arbitration Over Alleged Forged Retirement Deed
The Supreme Court has held that two non-signatory partners must be made parties to an arbitration over a commercial unit in Worli, Mumbai, because the outcome of the dispute, which turns on an allegedly forged retirement deed, would substantially affect their own rights to the property.
A Bench of Justice J.B. Pardiwala and Justice K. Vinod Chandran modified a High Court order that had refused to join the 3rd and 4th respondents in the arbitration on the ground that they had not signed the 1985 partnership deed containing the arbitration clause. The Court found them to be veritable parties on a prima facie view, while leaving their objections on limitation and estoppel open for the Arbitral Tribunal to decide.
The Court opened its judgment by describing the veritable party question as a vexing one that arises more often than ever and cannot be reduced to a strait jacket formula. The answer, it said, depends more on the facts than on any fixed rule.

Bench: Justice J.B. Pardiwala and Justice K. Vinod Chandran (author)
What Was Challenged: High Court order under Section 11 of the Arbitration and Conciliation Act, 1996, refusing to join non-signatory respondents in the arbitration
Date of Judgment: 12 October 2026
Outcome: Order modified; 3rd and 4th respondents held to be veritable parties on a prima facie view; limitation and estoppel left to the Arbitral Tribunal
Background: A Worli Property and Five Decades of Partnership Deeds
The dispute concerns Unit No. 2, a 3,500 sq. ft. ground floor unit in Manish Commercial Centre, Dr. Annie Besant Road, Worli, Mumbai. The property was acquired by a partnership firm, M/s Prospective Traders, and its ownership has passed through a long chain of reconstitutions.
The Chain of Deeds
2 April 1977: Partnership formed between three family trusts of V.U. Shah, N.U. Shah and C.U. Shah.
3 October 1977: The firm acquires the Worli unit.
9 December 1985: Firm reconstituted; the appellants (Hemant D. Shah HUF and his wife) and the 1st and 2nd respondents (Chittaranjan D. Shah HUF and the daughter-in-law of C.D. Shah) are inducted as partners. This deed contains the arbitration clause.
30 December 1987: Firm reconstituted again and the original partners retire. The appellants dispute this deed.
3 July 1995: Deed of retirement under which the appellants are said to have retired. The appellants allege it is forged.
1 July 2005: The 2nd respondent retires; the firm is dissolved and continues as a proprietorship with assets vested in the 1st respondent.
30 September 2009: The 3rd and 4th respondents are brought in as partners, forming a new partnership.
4 November 2009: The 1st respondent retires; the 3rd and 4th respondents continue as partners.
The appellants maintain that they never retired, that the 1985 partnership still subsists, and that the Worli unit belongs to that partnership. Notably, an earlier arbitral award obtained at the appellants' own instance had been set aside under Section 34 of the Act, so this was their second attempt at arbitration.
What the High Court Decided
Deciding the Section 11 application, the High Court first found the limitation question in the appellants' favour as against the 1st and 2nd respondents. However, it refused to join the 3rd and 4th respondents, holding that they had not signed the arbitration agreement, were not persons claiming through or under a signatory, and were not covered by the Group of Companies doctrine. The High Court relied on Cox and Kings Limited v. SAP India Private Limited and Hindustan Petroleum Corporation Limited v. BCL Secure Premises Private Limited.
The Law on Non-Signatories: Cox and Kings Revisited
The Supreme Court held that the claiming through or under principle and the Group of Companies doctrine discussed in Cox and Kings did not directly apply here. But the broader principles of that Constitution Bench judgment did help resolve the question. Cox and Kings treated arbitration law as an autonomous field concerned with whether a tribunal has jurisdiction, and held that courts cannot rigidly exclude persons who, through their conduct and relationship with the signatories, are bound up with the underlying contract.
The Court extracted three conclusions from Cox and Kings: that the written agreement requirement under Section 7 does not exclude binding non-signatories; that at the referral stage the court should leave it to the tribunal to decide whether a non-signatory is bound; and that the Group of Companies doctrine does not exclude other doctrines for binding non-signatories.
It then referred to Hindustan Petroleum, which held that a Section 11 court may examine prima facie whether a non-signatory is in the real sense a party, without taking away the tribunal's power to decide the question finally. In that case, a sub-contractor's attempt to drag the tender-floating corporation into arbitration failed because there was no semblance of a legal relationship between them.
Why the Non-Signatories Are Veritable Parties
The Court's reasoning rested on a simple chain of consequences. The real bone of contention is the 1995 retirement deed. If that deed is found invalid, the parties revert to the 1985 partnership, which contains the arbitration clause. In that event, the later partnership through which the 3rd and 4th respondents claim rights over the Worli unit would fall, because it exists only if the appellants validly retired.
On the facts and circumstances of this case, we are of the opinion that 3rd and 4th respondents are veritable parties to the dispute, since it would substantially affect their rights also...
In other words, the dispute is about ownership of the Worli unit, whether it flows from the 1985 deed or the 2009 deed. Those who hold under the 2009 deed cannot be kept out of a proceeding that may decide whether that deed survives.
What Remains Open Before the Arbitral Tribunal
The Court took care to limit the effect of its finding. The 3rd and 4th respondents had raised two objections that the Court expressly left alive:
Limitation: whether the claim against them is time-barred.
Estoppel: whether the appellants are barred from joining them now, having left them out of the earlier arbitration despite knowing of the retirement deed at that time.
The Court stressed that its finding is only prima facie and will not govern the Tribunal's adjudication of the veritable party question, limitation or estoppel. The impugned order was modified only to the extent of treating the 3rd and 4th respondents as veritable parties, and the appeal was disposed of.
What It Means Going Forward
Signature Is Not the Last Word
This ruling shows that a non-signatory can be pulled into arbitration not only through corporate group structures or derivative claims, but also where the outcome would directly determine its title to the disputed asset. At the same time, the Court has left a sting in the tail: the appellants' earlier decision not to include these parties may still cost them before the Tribunal.
For Claimants Seeking to Join Non-Signatories
Show how the non-signatory's rights depend on the very instrument or transaction in dispute. A clear chain of title or rights, as in this case, can establish prima facie veritable party status even without corporate links.
For Non-Signatories Resisting Joinder
Losing at the Section 11 stage is not the end. Limitation, estoppel and the final veritable party question remain open before the Tribunal, which decides them on evidence.
For Referral Courts Under Section 11
Referral courts can form a prima facie view on non-signatories, but where the facts show the dispute directly affects them, the safer course is to include them and leave the final call to the Arbitral Tribunal.
Note: This is a Non-Reportable judgment, decided largely on its own facts, but it applies the Cox and Kings framework in a family partnership and property setting outside the usual group company context.

Frequently Asked Questions
What did the Supreme Court hold in Hemant D. Shah HUF v. Chittaranjan D. Shah HUF (2026 INSC 1111)?
The Supreme Court held, on a prima facie view, that two non-signatory partners were veritable parties to an arbitration over a Worli commercial unit, because the dispute over an allegedly forged retirement deed would substantially affect their rights. It modified the High Court's Section 11 order to include them.
Who is a veritable party in arbitration?
A veritable party is a person who has not signed the arbitration agreement but is, in substance, a real party to the dispute because of its relationship with the signatories, its conduct, or because the outcome directly affects its rights. Whether someone is a veritable party depends on the facts of each case.
Can a non-signatory be bound by an arbitration agreement in India?
Yes. Following Cox and Kings Limited v. SAP India (2024) 4 SCC 1, the written agreement requirement under Section 7 of the Arbitration and Conciliation Act does not exclude binding non-signatories, through doctrines such as Group of Companies, claiming through or under, or veritable party status.
Can a Section 11 court decide whether a non-signatory is a party?
A Section 11 court can form a prima facie view on whether a non-signatory is a veritable party, as recognised in Hindustan Petroleum v. BCL Secure Premises. The final decision, based on evidence, remains with the Arbitral Tribunal.
Can a non-signatory still raise limitation and estoppel after being joined?
Yes. In this case, the Supreme Court expressly left the 3rd and 4th respondents' objections on limitation and estoppel open to be decided by the Arbitral Tribunal, along with the final veritable party question.
