An expectant heir accepting consideration and relinquishing future claims is estopped from asserting inheritance rights.

The plaintiff, widow of Late Sharat Maira—the only son of Late Satinder Nath Maira and Late Sudesh Maira—instituted a suit for partition, declaration, permanent injunction and rendition of accounts concerning her parents-in-law’s estates, including the Anand Lok Property.

She claimed that Satinder Maira died intestate in 2018 and that, as the widow of his pre-deceased son, she inherited an equal share with Sudesh Maira under Section 8 of the Hindu Succession Act, 1956.

Sudesh Maira died in 2024, after which the plaintiff claimed entitlement to the estates.

She alleged that a Will dated 10 June 2019, bequeathing the estates to Defendant No. 1/Trust, was forged and procured through undue influence by Defendant No. 2.

The defendants relied on a Consent Order dated 22 March 2010, under which the plaintiff received ₹2 crores from the sale proceeds of the Sunder Nagar Property and agreed to have “no claim of any nature, whatsoever” against Satinder Maira and/or his family.

The defendants contended that this settlement created an equitable estoppel against the plaintiff’s subsequent inheritance claim.

Whether the plaintiff’s claim to the estates of Late Satinder Nath Maira and Late Sudesh Maira was prima facie barred by the Consent Order dated 22 March 2010 and the doctrine of equitable estoppel.

Whether the plaintiff could assert inheritance rights in the subsequently acquired Anand Lok Property notwithstanding the broad relinquishment recorded in the Consent Order.

Whether the disputed character of the Sunder Nagar Property and the alleged forgery or invalidity of the 2019 Will prevented the Court from deciding the interim-injunction application in favour of the plaintiff.

Whether the plaintiff had established a prima facie enforceable right warranting an ad interim injunction under Order XXXIX Rules 1 and 2 CPC.

The Court applied the doctrine of equitable estoppel under Section 115 of the Indian Evidence Act, 1872, holding that although a bare relinquishment of spes successionis—a mere expectation of inheritance—may not itself constitute a valid transfer, an expectant heir who accepts valuable consideration and induces the owner to act on the basis that no future claim will be made may be estopped from asserting the subsequently vested inheritance right.

Relying on Gulam Abbas v. Haji Kayyum Ali, (1973) 1 SCC 1, Shehammal v. Hassan Khani Rawther, (2011) 9 SCC 223, and Elumalai v. M. Kamala, (2023) 13 SCC 27, the Court held that acceptance of consideration in exchange for relinquishing future inheritance claims can create a binding estoppel, even where the underlying relinquishment concerns spes successionis.

The Court also considered Section 6 of the Transfer of Property Act, 1882, concerning the non-transferability of a mere expectancy of succession, and Section 8 of the Hindu Succession Act, 1956, while recognising that statutory inheritance rights may nevertheless be defeated by estoppel arising from the claimant’s conduct.

At the interlocutory stage, the plaintiff was required to establish a prima facie case, balance of convenience and the likelihood of irreparable injury.

The Court found that the Consent Order used deliberately wide and unqualified language: upon receipt of ₹2 crores, the plaintiff agreed to make no claim “of any nature, whatsoever” against Satinder Maira and/or his family.

The consideration was paid and the settlement was implemented.

The Court rejected the argument that the relinquishment was confined to the Sunder Nagar Property or could not extend to the Anand Lok Property, which was acquired in 2012, holding that the obligation was personal and blanket rather than property-specific.

The plaintiff’s prior knowledge of Satinder and Sudesh’s intention to create a charitable trust, evidenced by the 2009 correspondence, reinforced the conclusion that she had agreed to give up future claims so that the parents-in-law could deal with their estate without the prospect of later inheritance litigation.

Applying Gulam Abbas, Shehammal and Elumalai, the Court held that the plaintiff’s acceptance of valuable consideration and subsequent conduct generated an estoppel, notwithstanding that the inheritance rights had not crystallised in 2010.

Consequently, the disputed ancestral or self-acquired character of the Sunder Nagar Property and the authenticity of the 2019 Will were not necessary to determine the interim application.

The plaintiff therefore failed to show a prima facie enforceable right against the estates.

The application under Order XXXIX Rules 1 and 2 read with Section 151 CPC seeking ad interim injunction and preservation of the estate was dismissed.

The Court clarified that its observations were tentative and confined to adjudication of the interim application, without expressing a final opinion on the property’s character or the validity of the Will.

The suit was directed to be listed before the Joint Registrar on 6 October 2026.
