Crypto Guide

In this article, we're breaking down how to inherit crypto assets, especially if you use custodial and self-custody platforms and live in the US, Europe, and Latin America.

Key takeaways

Around 4 million BTC (~$40B) are already lost to death. 89% of holders worry about it, yet only 23% have a documented plan and just 7% have a will, versus 32% of the general public.
No major exchange lets you name a beneficiary: not Coinbase, not Binance, not Kraken. Your heirs go through probate first, then through a customer support ticket.
You inherit access, not coins. What passes on is the private key: the ability to sign a transaction. If your heirs can't reproduce it, the crypto stays on the blockchain forever: visible to everyone, spendable by no one.
Never put your seed phrase or private key in your will. Probate files can become public records. Keep the existence of the assets in the will and the access in a separate, private channel.
Real solutions exist, sized to what you hold: a plain-language letter of instruction for small amounts, Shamir-split backups for meaningful sums, and multisig with a time delay (Casa, Nunchuk, Unchained) for serious stacks.

Your uncle dies. He was into Bitcoin, and you know this because he wouldn't shut up about it at Thanksgiving or Christmas. The family finds a laptop, a notebook with some words in it, and a small metal rectangle in a drawer that nobody recognizes.

Now what?

If it were a bank account, the answer is boring and well-worn: you get a death certificate, you get a court to appoint you as executor, you walk into a branch, and eventually the money moves. It sounds annoying and boring, but it works. Millions of people do it every year, maybe every day.

Crypto doesn't work like that, and understanding why is worth it because almost everything else follows from it. Let's look at some numbers.

4 million BTC (approx 40 billion USD) has been forever lost due to death

This number comes from the Coincover research. Moreover, 89% worry about what happens to their crypto when they die.

The Cremation Institute study also says that only 23% of investors have a documented plan. In the general population, about 32% of adults have a will. Among crypto holders, it's 7%.

These are very sad numbers, aren't they?

Except for these numbers, there is one more take: crypto skews young (yes, people 30+ and 40+ are still young people), and they don't think about dying.

We'd like to fix that because crypto is worth preserving and passing down to future generations.

Let's return to your uncle's heritage. Sorry for this example, but this is our reality that you might face.

In fact, you inherit access to crypto, not the coins themselves

Blockchain is a public ledger, so you access coins through a crypto wallet.

What your uncle actually owned was the ability to sign crypto transactions: to produce a cryptographic proof that authorizes moving those entries somewhere else. That signing ability comes from a private key. The key is the asset.

Thus, you'll inherit private keys but not coins. That means your uncle had to consent to inheriting the keys, not the coins.

The next question you need to ask yourself is, does someone else hold the keys, or do you?

That single fork determines everything: who your heirs talk to, what documents they need, how long it takes, and whether the money is recoverable at all.

Fidelity's estate planning team has a good phrase for the self-custody side: they call crypto a bearer instrument. Whoever physically has the key is treated as the owner, full stop. Not who the will says. Not who the judge says. Whoever has the key.

Let's take the two branches one at a time.

If your crypto sits on a centralized exchange

This is the recoverable case. If your coins are on Coinbase, Binance, or Kraken, the exchange holds the keys, not you. There are companies with a legal department in a jurisdiction that can be compelled to hand things over. Your heirs will get the money.

You cannot name a beneficiary. Anywhere

Your brokerage account has a beneficiary designation. Your 401(k) or another pension plan has one. Your bank account probably has a payable-on-death form sitting in a drawer somewhere. You fill in a name, and when you die, that asset skips probate entirely and lands in that person's hands in a few weeks.

Crypto exchanges don’t offer this. Not one of the major ones.

Kraken is the only exchange that says so out loud. Their help center has an article whose entire purpose is answering "can I set a beneficiary or nominee?", and the answer is no.

Coinbase says essentially the same thing in less direct language: individual accounts don't support beneficiaries, and what happens to the balance is determined by your estate documents or, if you didn't leave any, by your state's intestacy law.

Thus, you cannot name a beneficiary for your crypto account on a CEX platform itself, but you can do that outside it. For example, to create a last will and testament and name your beneficiary for your crypto account using a special company or your advocate. After your passing, your family members can appeal to a CEX to access your account with these documents.

So the path isn't "fill in a form now." The path is: die → probate court → letters testamentary → customer support ticket → wait.

What your heirs actually have to do, exchange by exchange

We went through the published policies. Here's the whole picture.

The list of useful links to get more details from this table:

The details that actually bite

Your heir needs their own account. Coinbase and Binance don't wire cash to a stranger's bank. They transfer crypto to a verified account, which means your heir has to sign up, pass KYC, and learn what a withdrawal address is.

Binance wants certified copies, not scans. Which means notary appointments and, if the deceased lived abroad, possibly an apostille. Start early. Binance.US wants a video of your heir's face.

Two-factor authentication is a wall. Your heirs can't just log in with a password from your notebook. The 2FA code goes to your phone. And logging into a dead person's account with their credentials is generally a bad idea anyway: it can violate the terms of service, it can look like identity misuse, and it can get the account frozen with a compliance flag, which turns a two-month process into a nightmare.

Kraken gives one genuinely good piece of advice, and it costs you nothing: put your public account ID in your will. Not your password. Not your keys. Just the account number, so your executor knows the account exists and can prove which one is yours.

How long, realistically?

Deadlines vary and often depend on your specific case. The whole time, the market does whatever the market does.

If you hold your own keys

Self-custody is where crypto stops being a financial planning problem and starts being an engineering problem. There is no company to sue, no support desk to escalate to, no judge who can order the blockchain to do anything. If your heirs can't reconstruct your signing ability from what you left behind, the money is simply gone: visible on-chain forever, spendable by nobody, for the rest of time.

But what if you could just write your seed phrase down in your last will and testament?

Why "write the seed phrase down" is not a plan

The standard advice is: write your twelve or twenty-four words on paper, hide the paper, done. However, anything could happen. For example, your heirs may never have heard of crypto and could use the seed phrase incorrectly. They can also become victims of scams, and so on.

The failure mode isn't cryptographic. It's human. But how to avoid that?

Mechanisms that actually work

The good news is that this problem has been worked on seriously for about a decade, and there are now real answers. They fall into a few groups.

1. Multisig with a waiting period. For example, Casa.

Your heir gets a sealed, encrypted key they cannot use and cannot even see the balance with. When you die, they request recovery, and a six-month clock starts, during which Casa emails you every month asking if you're still alive. If you don't answer, the key unlocks. If you were just on a long trip with no signal, you'd answer, and nothing would happen. It starts around $250 a year and requires no KYC.

2. On-chain timelocks. Instead of trusting a company to release a key, you write the inheritance into the coins themselves.

Nunchuk and Liana both do versions of this: you give your heir a recovery key that mathematically cannot spend anything until a certain amount of time has passed with no activity from you.

If the company disappears tomorrow, the plan will still execute because the rule lives on the blockchain, not in a database. One catch worth knowing: the relative timelock resets based on when coins were received, so you have to periodically "refresh" the setup or the clock starts running earlier than you think.

3. Shamir backup (SLIP-39).

Instead of one seed phrase, you split it into shares, say five, any three of which can rebuild it. No single share reveals anything. You can give one to your brother, one to your lawyer, one to a safe deposit box.

Nobody can steal your money by finding one piece, and nobody can lock your heirs out by losing one. For example, Trezor has made this the default backup on its Safe line since June 2024.

4. Collaborative custody.

Unchained runs 2-of-3 vaults where they hold one key and walk your heirs through the process by hand. You're trading some independence for a human being who picks up the phone.

5. Smart contract wallets and social recovery.

On Ethereum and similar chains, account abstraction lets you write recovery logic directly into the account: guardians who can vote to restore access, spending rules, dead-man switches. Lukas Schor of Safe has argued that this is where banks, insurers, and notaries eventually re-enter the picture, not as custodians, but as guardians. It's early, but it's the most likely long-term answer.

The argument against all of this

Anthony S. Park, an estate professional, makes a blunt case: Casa, Unchained and Nunchuk are single points of failure wearing a decentralization costume. They're businesses. They can shut down, get acquired, change pricing, or get hacked. And, this is the sharper point: they're a known, subpoenable address. In a divorce, a lawsuit, a tax dispute, or a creditor action, an opposing lawyer who knows you use Casa knows exactly where to send the subpoena. A piece of paper in your safe has no legal department to serve.

He's not wrong. The counterpoint is equally real: Casa says that when they try to help families who had no plan at all, recovery takes six to twelve months and usually fails.

So the honest framing is this. Every inheritance plan trades one risk for another. Doing nothing trades convenience for a very high chance that your heirs get zero. Using a service trades some privacy and independence for a dramatically better chance of getting everything. Splitting shares yourself trades simplicity for the risk that your brother-in-law loses an envelope.

Pick your trade deliberately. Just don't pick "I'll deal with it later," because that's a trade too, and it's the worst one.

The law: what actually governs your crypto after you die

Two things have to be true for your heirs to end up with your crypto. They have to be legally entitled to it, and they have to be technically able to get it. Everything above was about the second one. This is the first.

United States

For your heirs to get your crypto in the US, two systems have to cooperate: the law that decides who's allowed to open your accounts, and the tax rules that decide what they owe once they do. Here's both, in plain terms.

There's a law, RUFADAA, that every US state has now adopted in some form. It decides who has the legal right to access your online accounts after you die. Think of it as the rulebook that the exchange or the court follows. According to this law:

1. A setting inside the account itself beats everything. Some platforms let you name, right there in the settings, who takes over if you go inactive. For example, Google has an option called "Inactive Account Manager," and Facebook has "Legacy Contact." If you filled one of those out, it wins. It even overrides your will. (Most crypto exchanges don't offer this, which is exactly the problem, but it's worth knowing the setting exists where it does.)

2. If there's no such setting, your will takes over, but only if it says the right thing. Here's the catch that trips people up: a normal will doesn't automatically cover your online accounts. It has to specifically say your executor is allowed to access your digital assets. If your will is silent on that, your executor can be left locked out even though they're clearly in charge of everything else.

3. If neither of those exists, the company's terms of service decide, and as we've seen, that usually means your heirs are stuck emailing support and getting nowhere.

The conclusion is that you should take into account all the details and write them down in your testament.

United Kingdom

The UK tax office (HMRC) settled the basics years ago. Crypto counts as property for inheritance tax, and what matters is where you live, not where the exchange is. If you're a UK resident, your crypto is treated as UK-based. Moving it to a foreign exchange changes nothing. Inheritance tax is 40% on everything above the tax-free threshold, and this is the key part. It's calculated on the value on the day you died.

Say your crypto was worth £2 million the day you died. Your heirs can't find the keys for three years. By the time they do, the market has crashed 70%, and the coins are now worth £600,000.

They still owe inheritance tax on the full £2 million. The clock froze on your date of death; the later crash doesn't reduce the bill by a penny. And because the paperwork came in late, there's interest and possibly penalties piled on top. It's entirely possible for the tax to end up larger than what your heirs actually recover.

And HMRC is watching now. Since January 2026, it's been sending warning letters to families it suspects didn't report crypto, and new international rules mean it increasingly sees what the exchanges see. Hiding it is no longer realistic.

One warning for whoever handles the estate: don't just log into the deceased's account. In the UK, accessing someone's account without proper legal authority can break the Computer Misuse Act. Get the authority first, then log in.

The European Union

Since 2015, one rule covers inheritance across the EU: Regulation 650/2012. A single country's law governs your whole estate, the law of wherever you were living when you died, and it applies to everything you owned, no matter where it sits. You can instead pick the law of your home country, but only if you say so explicitly.

There's also a handy tool most people have never heard of: the European Certificate of Succession, one document that proves who the heirs are and is accepted across the EU.

Two caveats: the rule doesn't apply in Denmark or Ireland, and it doesn't touch tax; inheritance tax stays national. And MiCA, the EU's big crypto law, says nothing about inheritance at all.

Latin America

Brazil has no crypto-specific inheritance law, but it has something more dangerous: visibility. Since 2019, exchanges have reported customer holdings to the Receita Federal (IN 1.888/2019), and Lei 14.478/2022 lets courts compel exchanges to disclose data.

The tax authority knows the deceased declared 10 BTC. It assesses ITCMD, a state-level inheritance tax capped at 8%, on that value. The heirs owe the tax. They cannot access the coins because nobody left them the keys. They now have a real debt on an imaginary asset. Assets move through a formal inventário, which produces the documents that an exchange will actually accept.

Argentina has no specific rules at all. Crypto fits awkwardly into the Civil and Commercial Code. It's neither a "thing" nor a "right" in the classical sense, so doctrine has invented the category of "digital assets" to hold it. Heirs can ask a court to order ARCA (the former AFIP) or the central bank to disclose known holdings.

Mexico is the friendliest of the three. Crypto is inherited as ordinary property through a notary: inventory, adjudication, done. There's no inheritance tax, though the heir has to report the receipt. Mexico City's civil code was reformed in 2021 to specifically address digital assets.

7 Steps: what to actually do

You don't need a lawyer to start. You need an hour and a notebook.

1. Make an inventory. No keys in it. List what you own, roughly how much, and where it lives, which exchanges, which wallets, which hardware devices. That's it. This document is not sensitive if it contains no credentials, and it solves the single biggest problem: your heirs don't know your crypto exists. They can't recover what they never look for. Kraken's advice is right: put the public account ID in there.

2. Never, ever put a private key or seed phrase in your will. Wills go through probate. Probate files can become public records. You would be publishing your keys with a delay fuse on them. Same goes for any document that gets filed with a court.

3. Write a letter of instruction for someone who knows nothing. Separate from the will. Assume the reader has never used crypto. Where the hardware wallet is. What a PIN is. That a "recovery phrase" should never be typed into a website. Which app to download and from where, with the exact URL, because the fake one ranks well on Google. If you use multisig, say so, explain how many keys are needed and where each one is, in plain words.

4. Give your fiduciary explicit legal authority. This is the paragraph a lawyer earns their fee on. Your will, trust, or power of attorney needs language that expressly authorizes your executor to access digital assets.

5. Consider a trust. A trust holds the assets, skips probate entirely, stays private, and lets you name someone crypto-competent to handle just this piece. For anything above "fun money," this is usually the right structure.

6. Add a technical layer sized to what you hold.

Small holdings: a good letter of instruction plus a sealed envelope with a trusted person may genuinely be enough.
Meaningful holdings: Shamir shares, split geographically. No single person holds enough to steal, no single loss locks you out.
Serious holdings: multisig with a time delay: Casa, Nunchuk, Liana, Unchained. Pay for it. It's cheaper than the alternative.

7. Do a dry run. This is the step everyone skips, and it's the most important one. While you're alive and healthy, have your heir actually walk the process. It can give you an understanding of where potential problems may arise.

Frequently Asked Questions

Can cryptocurrency be inherited?

Legally, yes, everywhere. Crypto is property, and property passes to heirs by will or by intestacy law. Practically, only if your heirs can access it. Legal entitlement without the keys is a piece of paper describing money nobody can spend.

What happens to Bitcoin if you die without a will?

It passes under your state’s intestacy laws typically to a spouse, then children. But intestacy determines who owns it, not who can reach it. If nobody knows the keys exist, the coins stay on the blockchain permanently, no matter what the court decides.

Can an exchange recover my crypto if I lose my seed phrase?

Not for a self-custody wallet. No one can not the exchange, not the wallet company, not law enforcement. That’s the design. If the exchange holds the keys (Coinbase, Binance, Kraken), then yes, they can reset your access, because it was never really your key to begin with.

Should I put my private key in my will?

No. Wills can become public records during probate. Put the existence of the assets in the will and move the access through a separate, private channel: a letter of instruction, a sealed deposit, a notarial act, or an inheritance service.
