Eleven months into owning a laptop, the screen began to fail. It was under warranty. I knew it was under warranty. What I could not do was prove it, because the receipt was in an email account I no longer used, under a subject line I could not guess, sent by a retailer whose order system had since changed hands. The claim died there. Not because the cover had lapsed, but because I could not assemble, on the one day it mattered, the evidence that the thing was mine and when I got it.
The tidy response is to keep better records. Scan the receipt, file the warranty, back it up. I believed that for a while, and I built the first version of a logbook around it: a nice place to put the documents I should have kept.
A personal failing
The obvious reading is that this is a personal failing. People are disorganised. We lose receipts, we forget service dates, most of us could not tell you what our contents insurance actually covers. Keep a folder, the advice goes, and the problem goes away.
It is true as far as it goes, and it does not go far. The strange part is that nothing I needed had ever been lost. Every fact about that laptop existed, held by somebody. I just was not one of the somebodies. The claim did not fail for lack of information. It failed because none of the information lived with me.
The record stays with the seller
The problem, I decided at first, was memory: a filing failure, fixable with discipline. That diagnosis did not survive a second look at where the documents actually were. The proof that you own a thing is scattered across the people who sold it to you, and none of them has any reason to hand you a durable copy.
The retailer holds your receipt, until they migrate systems. The manufacturer holds your warranty, keyed to a serial number you never wrote down. The mechanic holds your car’s service history, in a database you cannot see. The market holds the current value, if you know where to look. You are handed the object. You are almost never handed the record.
The proof and the thing are different objects
Once you see it that way, a pile of small frustrations line up behind one shape. A thing and the proof of the thing are two different objects. You take delivery of one and not the other. And the proof only turns urgent at the three moments the object cannot speak for itself: a claim, a sale, and a handover after a death.
An insurer rarely doubts that your house burned. It doubts what was inside it, and the burden of proving that sits with you: the practitioner guidance is blunt that without documentation an insurer may delay, reduce, or deny the payout. (ClaimsMate 2026) New Zealand has sat this test at national scale. In the legal post-mortem of the Christchurch earthquakes, the pattern from previous large disasters held: a third of the people hit are uninsured, a further third underinsured, and a large share of the difficulty traced to people who could not document their position when the moment came. (Rob Merkin 2012) A buyer rarely doubts that the watch is real. They doubt its history. A family settling an estate doubts nothing, and can price nothing.
In each case the failure is identical. The thing is present and the proof is absent, and the proof was absent from the very start, because no one ever gave it to you. We reconstruct it alone, from scratch, at the worst possible moment, every one of us repeating the same salvage job in private.
There is a reason it stays with the seller. To them your record is an asset: proof of a sale, a serial number tied to a support obligation, a service relationship worth renewing. To you the same record is only ever a liability, useful on the single day you need to call it in. The party who values it least is the one guaranteed to keep it, and the party who needs it most is handed the object instead. Nobody is behaving badly. The incentives simply point the wrong way, and they have pointed that way for so long that we mistake the result for our own disorganisation.
Who keeps the book
This is where a logbook stops being a tidiness app and turns into something closer to plumbing. Not a folder you are finally disciplined enough to maintain, but the missing counterpart to the receipt: a place where the record of a thing lives with its owner, assembled once, so it is already there on the day it is needed rather than rebuilt out of panic.
Whether that place should be run by an insurer, a bank, a startup, or nobody at all is a fair question, and I do not think the answer is obvious. An insurer that held your proof would also hold a quiet kind of power over your claim. What is not in doubt, standing in the wreckage of a warranty I should have won, is that the gap is real, and old, and steadily expensive. We have built careful machinery for proving what we earn and what we owe. We never built the same for proving what we own.
