A client's cousin — a software engineer in Bengaluru, unmarried, 34, Hindu by faith — died suddenly in 2023, leaving ₹68L spread across eleven mutual fund folios and a demat account holding direct equity. He'd told his family more than once, informally, that he wanted everything to go to his younger sister, who'd moved in with him for two years while he recovered from a serious illness and effectively ran his household during that stretch. He never wrote it down. There was no will.
What happened next surprised the family, because none of them actually knew the default rule. Under the Hindu Succession Act, when a Hindu male dies intestate — without a will — his Class I heirs inherit, and Class I heirs include his mother, his widow and children (he had neither), and his siblings only if the mother is also deceased. His mother was alive. Under the Act, she alone was the Class I heir. His sister — the one person he'd actually wanted to provide for — had no legal claim at all, unless their mother chose to gift or will her own inheritance onward later.
The law doesn't know what you told your family
This is the single biggest misconception I run into with unmarried or newly-independent clients: the belief that verbal intent, or even a clearly closer relationship, carries legal weight. It doesn't. Succession law applies a fixed hierarchy based on your religion and relationships as legally defined, full stop — it has no mechanism for “but he would have wanted.” For a Hindu male with no spouse or children, that hierarchy puts the mother ahead of siblings entirely, not as a split, as an exclusion. The sister in this case wasn't entitled to a smaller share. She wasn't entitled to anything.
The rules differ by religion and by whether you're male or female, married or not — Muslim succession follows entirely separate Shariat-based shares, Christians and Parsis follow the Indian Succession Act, and even within Hindu law the order changes based on who survives you. None of that complexity is optional reading if you die without a will. It simply applies to you by default, whether or not it matches what you'd have chosen.
What transmission actually looked like
The mutual fund folios transmitted to the mother in about six weeks once she submitted a death certificate, a legal heir certificate, and a notarised affidavit — straightforward, because there was exactly one Class I heir and no dispute about who it was. The demat account followed a similar path with the depository participant. Mechanically, intestate succession to a single, undisputed heir is not slow. The problem in this case was never the paperwork. It was that the ₹68L went entirely to someone the deceased hadn't specifically intended to prioritise, while the person he actually wanted to provide for received nothing, by operation of a law neither of them had read.
What a will would have cost him: one afternoon
A simple will naming his sister as beneficiary — witnessed, no registration even strictly required to be valid, though we always recommend it — would have overridden the default entirely and taken effect exactly as he intended. It's a document most unmarried professionals in their thirties assume is only relevant once they have a spouse and children, which is exactly backwards: it's because you have no spouse or children that the default succession order is most likely to hand your estate to someone other than who you'd choose. Drafting a first will, even a simple one, is the starting point of every estate planning conversation we have with unmarried clients, and it's consistently the one they're most surprised to learn they already need.
His mother, to her credit, later transferred a portion to her daughter voluntarily. That outcome depended entirely on her goodwill — the law gave her no obligation to, and gave the sister no claim to fall back on if she hadn't.
