Comparing dead man’s switch services: the four shapes
Four different products wear the same label. What actually separates them, which one suits which problem, and where we sit,…
The traditional answer to “how do I leave something for my family to find” is a sealed envelope lodged with the solicitor who holds your will. It is a good answer. It has worked for a century, it costs almost nothing, and it carries a weight that no web service will ever have.
It also cannot do several of the things people now need it to do, and the gap has widened every year since about 2005. This is an honest account of what each one is good at. We sell one of them, so the useful thing we can offer is precision about where ours does not belong.
A will is an instrument. It appoints an executor, it transfers property, it can be enforced. Nothing you upload to any service does any of that. If the question is who inherits the house, there is one answer and it is not a vault.
A letter of wishes lodged alongside the will is not binding either, but it is read in the room, by the people acting on the will, with the solicitor present. That context matters.
Most solicitors store a will free if they drafted it, and the profession has machinery for what happens when a firm folds. In England and Wales, if the firm closed, the Solicitors Regulation Authority can help trace where the will went. No technology company has an equivalent. This is the single strongest argument for paper, and it is why we tell people not to let any service — including this one — be the only place their plan exists.
An envelope in a fireproof cabinet has no password, no two factor code, no account recovery flow and no breach notification. That is not nothing.
A solicitor hands over a letter knowing who is sitting in front of them and what has just happened. Software delivers on a schedule to an address, and does not know that the address belongs to someone who died first.
This is the big one and it is structural, not fixable. A sealed letter sits there until a person who knows it exists contacts a firm that has learned you have died. Every link in that chain is a human remembering something. If nobody knows the envelope exists, nothing happens, ever.
Plenty of families discover a letter years later during a house clearance. A switch exists precisely to remove that dependency: it fires on a clock rather than on somebody’s memory.
People put passwords in wills. Do not do this.
In England and Wales, once probate is granted the will becomes a public document. The record appears online roughly a fortnight later, and anyone at all can order a copy — including the will — for £16. Probated wills are public court records across most of the United States and Australia too. A password written into a will is a password published, with your address attached, to anyone who cares to pay a small fee.
A separate sealed letter avoids that, because it is not part of the will and is not lodged with the court. But it inherits the timing problem below.
Probate in the United States commonly runs six to eighteen months depending on the state, and a contested estate can stay open for years. In England and Wales a grant takes weeks to months after the application, and the application itself takes time to prepare. That is the correct pace for transferring a house. It is the wrong pace for almost everything digital.
Consider what actually needs to happen quickly:
None of those can wait for a grant of probate. A letter opened in month eight is a letter that arrived after the damage.
Even with the right paperwork, an executor is not automatically entitled to the contents of your communications. Under the Revised Uniform Fiduciary Access to Digital Assets Act, adopted in some form by more than forty US states, a fiduciary can generally get the catalogue of a digital account — who you emailed, when — but the actual content of emails and messages needs explicit authorisation that you gave while alive.
Meanwhile the top of that same priority order is not the will at all: it is the provider’s own legacy tool. If you set up Google’s Inactive Account Manager or Apple’s Legacy Contact, that instruction outranks what your will says about that account. Your solicitor’s envelope sits below it.
You change a password every few months. A letter with a solicitor is updated by writing a new one and arranging to swap it. Almost nobody does this more than once. Which means the envelope is accurate on the day it was sealed and drifts from then on, quietly, for years.
Worth saying because it is such a common instinct. Do not put the will, or the letter that explains the will, in a bank deposit box. The bank generally cannot open the box until probate is granted, and probate needs the will. People genuinely do this and their families genuinely get stuck.
Not “one or the other”. They do different jobs, and the split is clean once you see it.
That third list is not an afterthought. Every plan built on a single service has one point of failure, and it is the service. Ours included.
If you take nothing else from this, add these to whatever your solicitor holds:
“A digital plan exists.” Name the service, name the email address the account is under, and name the person who has been told about it. Do not include a password. This one line is what turns a vault from a thing nobody knew about into a thing your executor can ask about.
“Do not treat anything in my will as confidential.” Obvious to a solicitor, not obvious to the person writing the draft at their kitchen table, and the reason passwords keep ending up in public court records.
Keep the solicitor. Write the will. Lodge the letter of wishes. None of that is replaceable and we are not going to pretend a subscription is a substitute for an instrument that a court will enforce.
Then take the two categories a will handles badly — secrets, and anything with a deadline shorter than probate — and put those somewhere with a clock on it. That is the entire argument for this kind of product, and it is a narrower argument than most of our competitors make.
If you want the practical version of the letter itself, we wrote how to write a letter of instruction your family can actually use, including a template. If you want to know what a vault does with a password once you put one in it, how your files are encrypted is specific about where the encryption starts and stops. And the free plan needs no card if you would rather look than read.
We are not lawyers and none of this is legal advice. Probate, public record rules and fiduciary access laws differ by country and by state, and the figures above are current as of September 2026. Ask your own solicitor about your own jurisdiction before you rely on any of it.
The Free plan gives you one vault and 100MB of encrypted storage. No card, no expiry.
