Here's a number that should sit uncomfortably with you: as of December 2025, unclaimed deposits sitting in Indian banks had crossed a staggering figure — much of it because a family member passed away and nobody in the family knew the account existed, where the passbook was, or how to claim it.
This money doesn't vanish. It just sits there, out of reach, because the person who knew where it was is gone and never wrote it down. That's not a legal problem. It's a communication problem — and it's completely solvable in one evening with a pen, or twenty minutes with a form.
We built a free tool for this: the Family Passbook. Below is why it exists, and the questions people usually ask before trusting something like this with their family's details.
Why would a healthy 35-year-old need this?
Because "suddenly" is the whole point. Life insurance, health insurance, and even Wills are built around the idea that something unexpected can happen — an accident, a medical emergency, a stroke that isn't survived. Nobody plans for the day; everybody should plan for what happens after the day.
Think about what your spouse would actually need to know, cold, with no warning: which banks you bank with, whether a nominee is even registered, whether your home loan has a cover that could pay it off, where your insurance documents physically are, whether you have a Will, and who your company's HR contact is for gratuity and dues.
Most people carry all of this only in their own head. That's the single point of failure a document like this removes.
Isn't a nominee enough? Why do I need anything more?
A nominee is a trustee for collection, not necessarily the final legal owner of the money — that distinction alone causes enormous confusion and delay in Indian families. Banks, insurers and mutual funds each have their own claim process, their own forms, and their own paperwork quirks by branch.
Knowing a nominee is registered is useful. Knowing which accounts exist, which have a nominee, and where the paperwork is kept is what actually gets a family through the process in weeks instead of months.
Government-owned banks alone are sitting on roughly ₹50,900 crore in dormant, unclaimed deposits — a large share traceable to depositors who passed away without a nominee or legal heir ever coming forward.
Won't writing this all down in one place be risky?
This is the part most "in case of emergency" templates get wrong, and it's why we designed the Family Passbook differently: it never asks for account numbers, card numbers, or passwords. A document like this can be printed, photocopied, or photographed by accident — so instead of the sensitive number itself, it only records which institution the account is with, whether a nominee is registered, and where the actual document is physically kept.
The tool runs entirely in your browser — nothing you type is sent to a server, saved in a database, or visible to us. You fill it, print it or save it as a PDF, and that's the only copy that exists.
What should actually go in it?
A useful version covers, in roughly this order of urgency:
- 1Emergency card — spouse, doctor, CA, lawyer
- 2First 7 days — what to do, and what to avoid
- 3Every bank account and where records are kept
- 4Every insurance policy and its agent
- 5Loans, and whether a cover policy exists
- 6Investments — MF, PF, NPS, PPF, demat, gold
- 7Property and vehicle documents
- 8IDs and the Will, if one exists
- 9Digital accounts — not passwords, just the door
- 10Employer HR contact for gratuity, PF
- 11Children and dependents' immediate needs
- 12Where everything above is physically kept
We've built exactly this into the free tool, with all twelve sections ready to fill.
Do I need a Will as well?
Yes — this passbook is a companion to a Will, not a replacement for one. A Will (ideally registered) determines legal ownership and prevents your family from needing a legal heir certificate, which can take months to obtain through the courts in its absence. The Family Passbook simply makes sure that once ownership is settled, your family can actually find and claim everything — which a Will by itself doesn't help with.
How often should I update it?
Once a year is a reasonable rhythm — around the time you file your ITR is an easy date to remember, since you're already looking at your financial year in one place. Update it sooner if you open a new account, take a new loan, buy insurance, or your family situation changes.
Where do I keep it once it's filled?
Print one copy and keep it with your other important documents — the same drawer or folder as your property papers. Tell your spouse, and one other trusted family member, that it exists and where it is. A passbook nobody knows about defeats the purpose.
