Could Your Family Recover Your Bitcoin Without You?

Most people who ask this question have already done the hard part. The keys were generated properly, the backups are distributed across locations, the passphrase is memorized, and the whole arrangement reflects real care and real thought. Whatever risks remain, carelessness is not one of them.

And then there is the other question, the one that tends to arrive at two in the morning: if you did not wake up tomorrow, could your spouse actually get to it?

This is a different problem from the one you already solved. It is an asymmetry problem, and it is worth naming precisely, because it is the single most common failure in otherwise carefully built bitcoin custody.

The asymmetry

Every decision you made when you built your setup, you made as the person who understands bitcoin, at a desk, calm, with time and the internet and the ability to try again if something did not work.

Every one of those decisions gets executed by someone else, one time, with no ability to practice, while grieving, possibly under time pressure from a probate court or a tax bill, and with nobody to ask. Your setup optimizes for the conditions of its creation. Recovery happens under the opposite conditions.

That gap is where bitcoin gets lost. Not to hackers. To a well-secured seed phrase in a safe deposit box that nobody knows how to use.

The honest test

Forget the technology for a moment and run this thought experiment.

Something happens to you tonight. Tomorrow, your spouse or your adult child is handed everything you left behind: the letter, the hardware, the location of the backups, whatever you have prepared. They have no technical background. They are in the worst week of their life. There is no one to call.

Do they end up with the bitcoin?

If you hesitated, you have found the gap. Most people do hesitate, and the ones who do not have usually tested it rather than assumed it, which is the entire point of what follows.

Three secondary questions worth asking yourself while you are here:

• What if you are alive but incapacitated? A stroke is more likely than a sudden death and almost nobody plans for it. Most inheritance arrangements do nothing in that scenario, because you are not dead and the estate process has not started.
• What if you both die at once? Couples travel together. Whoever inherits then is one further step removed from understanding any of this.
• What if your heir is a minor? Real situation that comes up constantly: someone wants to name a young child and discovers the child has no email address, no ID, and no legal capacity to hold anything. It needs a trust or a guardian arrangement, not a beneficiary line.

What each custody model actually asks of your family

This is the honest comparison. Each of these is a legitimate arrangement, and each asks something different of the person who has to execute it.

Self-custody, single signature. Your family needs to find the seed phrase, understand what it is, obtain compatible hardware or software, enter it correctly, and not be phished at any point during a process they have never performed. If a passphrase exists, they need that too, and they need to know it exists at all. A passphrase your spouse does not know about is functionally a coin burn.

Self-custody multisig. Everything above, times the number of keys, plus the wallet descriptor or configuration file. This is the one people underestimate most. A multisig without its configuration is unrecoverable even with every key in hand, and the configuration is not something a grieving spouse will intuit. It is also the setup most likely to have been built after the letter was written, so the letter describes the old arrangement.

Collaborative custody. Your family still needs to hold and use keys, but there is a company they can call who will walk them through it and who holds a backup key. That is a genuine and meaningful improvement, and Casa in particular has built real process around it. It is not the same as removing the requirement. Your heir still executes a recovery; they just are not alone.

An exchange. Varies enormously and is worth checking rather than assuming. Some have a documented estate process, some do not. Coinbase, for example, has no beneficiary designation for individual accounts, which means probate rather than a transfer. Your family will be dealing with a support queue and a legal process at the same time, which is not a disaster, but it is slow and it is not what most people picture.

Multi-institution custody. You name beneficiaries on the account with percentage allocations, and legal title transfers to them. There are no keys for them to find, no devices to obtain, no phrase to enter correctly. There are institutions with a documented process and people to talk to. This is the model Onramp operates, and inheritance is the most frequently cited reason clients move to it, which is why it is the one we understand best.

And a caution about all of it: whatever you choose, a lawyer who does not understand bitcoin will write you a will that does not work. Instructions in a will become public record in probate, so a seed phrase must never go in one. Plenty of otherwise careful estate plans have this exact defect.

What to actually do, starting today

Some of this involves us and most of it does not. In rough order of effort:

1. Test it, do not assume it. This is the highest-value thing on this page and it is free. While you are alive and well, sit your spouse down and have them attempt the recovery with you watching and not helping. Not a conversation about it. An actual attempt. Almost everyone who does this discovers something broken, and every one of those discoveries is one you got to make while it was still fixable.

2. Write the letter, then have someone non-technical read it back to you. Not what you meant. What they understood. Assume no prior knowledge, name the physical locations of things, explain what a seed phrase is before telling them where it is, and include what not to do: never type it into a website, never send it to anyone who calls claiming to help, never photograph it.

3. Make sure someone knows the account exists at all. Sounds obvious, gets missed constantly. The most robust arrangement in the world fails if nobody knows to go looking. Several of our clients describe their plan as simply: my family knows we have an account here, and they know who to call.

4. Handle the passphrase problem explicitly. If you use one, and your spouse does not know it exists, that is the highest-probability total loss in your setup. Solve it deliberately, whether through a sealed instruction, a trusted third party, or a different arrangement.

5. Deal with minors properly. If an heir is a child, a beneficiary designation is usually the wrong instrument. You need a trust or a named guardian, and it should be set up with someone who understands both estate law and bitcoin.

6. Then, and only then, consider whether the architecture itself should change. If you have run the test and it failed, and it keeps failing after you have fixed the letter and the process, the honest conclusion may be that the model is asking more of your family than they can deliver. That is when it is worth looking at collaborative custody or an arrangement where inheritance does not require your heirs to execute anything technical.

Frequently asked questions

What happens to my bitcoin if I die?

It depends entirely on how it is held. With self-custody, your heirs need to find your keys, understand them, and use them correctly with no help, and if any element is missing the bitcoin is unrecoverable. With collaborative custody, they execute a recovery process with a company that can guide them. With an exchange, they typically go through probate and a support process, and many exchanges have no beneficiary designation for individual accounts. With multi-institution custody, named beneficiaries receive legal title with no keys involved. Bitcoin held without any plan is simply lost, and there is no institution that can recover it.

How do I leave bitcoin to my heirs without them losing access to it?

Start by testing your current plan rather than trusting it: have your intended heir attempt the recovery while you are alive to watch. Write instructions assuming no technical knowledge and have a non-technical person read them back to you. Make sure at least one person knows the holdings exist. Never put a seed phrase in a will, which becomes public record in probate. If the test keeps failing, consider an arrangement where inheritance transfers by legal title rather than by key recovery.

My spouse is not technical at all. What is the simplest arrangement?

The simplest is one where your spouse inherits without performing any technical operation. That means naming beneficiaries on an account with a documented process and real people to call, rather than leaving keys and instructions. If you want to keep self-custody, the next best thing is collaborative custody, where a provider can walk them through recovery. If you keep pure self-custody, the burden stays with your family, and the mitigation is testing and documentation rather than architecture.

Can I name my child as a beneficiary if they are a minor?

Usually not directly, and this catches people out. A minor generally cannot hold assets or complete identity verification, and often does not have an email address. The normal solution is a trust or a named guardian who holds on the child's behalf until they come of age. Set it up with an attorney who understands both estate planning and bitcoin, because the two together are still uncommon.

What if I am incapacitated rather than dead?

This is the gap most plans miss. Death triggers an estate process; incapacity often triggers nothing at all. If you are alive but unable to sign, arrangements that depend on you signing are frozen, and arrangements that depend on your death have not activated. Worth asking any provider directly what happens in that scenario, and worth pairing your custody arrangement with a durable power of attorney that explicitly covers digital assets.
