The Supreme Court (SC) on Thursday granted interim relief to Rani Kapur in the escalating inheritance and promoter-control dispute linked to Sona BLW Precision Forgings Ltd (Sona Comstar), temporarily restraining key governance-related proposals at a promoter-linked investment entity amid an ongoing mediation process.
The development comes at a sensitive time for Gurugram-headquartered Sona Comstar, one of India’s largest automotive technology and EV component makers with a market capitalisation of around ₹30,000 crore.

Supreme Court pauses key board decisions
The latest hearing revolved around Raghuvanshi Investments Pvt. Ltd (RIPL), a promoter-linked investment vehicle associated with the Kapur family’s holding structure in Sona Comstar. Rani Kapur opposed certain agenda items, including proposed board-level changes and governance decisions, arguing that no structural moves should be undertaken while the family settlement process remains unresolved.
The apex court indicated that status quo should be maintained until mediation proceedings progress further. The Bench also underscored that no stakeholder should attempt to assume unilateral control over entities linked to the RK Family Trust during the pendency of the dispute.
The legal battle has pitted Rani Kapur — widow of Sona Group founder Surinder Kapur — against Priya Kapur, wife of late industrialist Sunjay Kapur, over inheritance rights, trust governance and control of promoter-linked assets tied to the broader Sona Group empire.
Investors track governance implications closely
The dispute has attracted significant attention in corporate circles because of the strategic importance of Sona Comstar in India’s fast-growing EV supply chain ecosystem. The company derives a substantial portion of its business from global battery electric vehicle platforms and counts several international OEMs among its customers.
Earlier this month, the Supreme Court appointed former Chief Justice of India D.Y. Chandrachud as mediator to explore an amicable settlement between the contesting family factions. Further, it has nudged litigants Rani Kapur and her daughter-in-law Priya Kapur to explore mediation in a bitter inheritance dispute over the Sona Group estate
Dispute intensified after Sunjay Kapur’s death
The roots of the conflict trace back to the death of Surinder Kapur in 2015, after which succession-related questions surrounding the family’s investment and trust structures gradually surfaced. However, the dispute intensified sharply following Sunjay Kapur’s death in 2025, triggering competing claims over the RK Family Trust and associated promoter-controlled entities.
Multiple proceedings linked to the estate, succession arrangements and trust governance are currently underway across judicial forums, including the Delhi High Court.
Sona Comstar, which supplies driveline systems, differential gears and traction motor components to global automakers across India, the US, Europe and China, reported consolidated revenue of over ₹4,449.5 crore in FY26, with EV programmes contributing a rising share of its global order book.
