New Demat Nomination Rules from September 2026: What Every Investor Must Do

Somewhere in India right now, a family is dealing with the aftermath of losing a parent, only to discover that dad’s demat account has no nominee on file. What follows is months of legal heirship certificates, succession documentation, and back-and-forth with the depository participant — all to access money that was, in every practical sense, already theirs. SEBI has been trying to fix this problem for years, and the revised nomination framework that kicks in from September 1, 2026 is its most sensible attempt yet.

Why SEBI keeps coming back to this

Unclaimed financial assets in India run into thousands of crores, and a huge chunk of that sits in demat accounts and mutual fund folios where the investor either never nominated anyone or the nomination process was so cumbersome that people gave up halfway. SEBI had earlier made nomination mandatory-or-opt-out for existing accounts, with the alternative being that the account gets frozen for debits. That earlier round created its own headaches — rigid documentation requirements, witness signature rules, and confusion among investors about what was actually required. The 2026 framework, notified in May, supersedes all of that with something genuinely simpler.

What changes from September 1, 2026

From that date, every new single-holder demat account and every new single-holder mutual fund folio must come with either a nominee on record or a formal, signed opt-out declaration. You cannot simply leave the field blank and move on — the account opening itself is incomplete without one or the other. This applies to accounts opened on or after September 1; SEBI has given depositories, depository participants, mutual fund houses, and RTAs the intervening months to update their systems, so don’t be surprised if your broker’s onboarding flow looks a little different by late August already.

Joint accounts get a pass. If you’re opening a demat account or mutual fund folio with a co-holder, nomination remains optional rather than mandatory, since the surviving joint holder already has a natural claim over the assets. But if you do want to add or change a nominee on a joint account, every joint holder has to consent — you can’t do it unilaterally.

The part investors will actually appreciate is the paperwork reduction. Under the revised rules, the only details that are mandatory for a nominee are their name and their relationship to you. If the nominee is a minor, you’ll also need to provide their date of birth so a guardian can be recorded. Everything else — PAN, Aadhaar, passport number, email, mobile number — is now optional. Compare that to the earlier regime, which effectively asked you to compile a small dossier on your nominee before the depository would accept the form. SEBI has also dropped the witness signature requirement for any nomination submitted with a regular signature; a witness is now needed only if you’re signing with a thumb impression.

Flexibility has improved too. You can nominate up to three people for a single demat account or mutual fund folio, and you can assign a specific percentage share to each of them. If you change your mind next year, you can modify, update, or cancel your nomination as many times as you like — there’s no limit, and no need to justify the change.

What you should actually do about it

If you’re opening a new demat account or mutual fund folio after September 1, this is simply built into the process now — your broker or fund house will ask you to nominate or opt out as part of onboarding, and you can’t skip it.

The more important question is for people who already have accounts. If you opened your demat account years ago and never got around to adding a nominee — or if you added one under the older, more paperwork-heavy process and it’s been sitting untouched since — this is a good moment to log into your DP’s portal and check. Most brokers now show nomination status prominently on the account dashboard. If it says “not nominated” or “pending,” fix it. It typically takes a few minutes online, and under the new rules, you don’t need to hunt down your nominee’s PAN or Aadhaar to do it — just their name and how they’re related to you.

If you hold multiple demat accounts across different brokers, or mutual fund folios across different fund houses, check each one separately. Nomination isn’t linked across platforms; a nominee registered with one broker doesn’t automatically apply to an account you hold elsewhere.

Families with wealth spread across three nominees might also want to think through the percentage split now rather than defaulting to an even three-way division. SEBI’s rules allow nominees to either continue holding the account jointly after the investor’s death or split off into separate accounts reflecting their respective shares — so a clearly specified split up front saves your heirs a negotiation later.

The bigger point

This isn’t a regulatory box-ticking exercise dressed up as investor protection — it genuinely addresses a problem that shows up at the worst possible time for families, right when they’re grieving and least equipped to deal with bureaucracy. SEBI’s own data on unclaimed assets sitting with the Investor Education and Protection Fund Authority has been climbing for years, largely because nomination compliance lagged. Simplifying the form is a small thing. Making sure your own accounts are actually updated is the part that’s on you.

Set a reminder for the last week of August: log into every broker and mutual fund platform you use, check your nomination status, and update it if it’s missing or stale. It’s a ten-minute task that could save your family months of hassle.
