Krishna Kumar Birla vs Rajendra Singh Lodha & Ors

The Supreme Court addressed the definition of 'caveatable interest' under the Indian Succession Act, 1925, particularly in relation to the rules established by the Calcutta High Court in 1940. The Court held that individuals who have a legitimate claim or interest in the estate of a deceased person can file a caveat against the grant of probate, thereby affirming the rights of the appellants to contest the probate of the 1999 Will executed by Smt. Priyamvada Devi Birla. The Court emphasized the importance of mutual wills and the need for clarity in testamentary documents.
