Crypto estate planning mistakes, and the one most make

You've probably thought about what happens to your bitcoin if something happens to you. Most crypto estate planning mistakes are easy to spot once someone names them. I'm naming them from the other chair, as the wife who would have to follow the plan.

My husband holds the bitcoin in self-custody. I'm not technical. For years I nodded through his explanations, and I couldn't have done anything with it. This article covers one part of crypto inheritance, and our full guide to bitcoin inheritance covers the rest.

Putting secrets in your will

It feels natural. The will is the serious document, so the seed phrase goes in the serious document. From my side, that's the worst place for it.

In many places, a will can become a public record once it goes through probate. Even before that, it's read by people who shouldn't see your seed phrase or private keys: lawyers, office staff, relatives, and an executor who may not be the person you'd trust with the savings. Anyone who reads the seed phrase can take the bitcoin.

What a will or a trust can do is say who inherits your crypto assets. Some people call that a crypto will or a crypto trust. Either way, it shouldn't hold a single secret word. Whether your estate plan uses a will, a revocable living trust, or both, the how-to belongs somewhere else. For what the legal documents should say, ask an estate attorney or another professional where you live.

Nobody knows the bitcoin exists, or only vaguely

You know exactly what you hold. Your family may know only that "there's some bitcoin somewhere." Or nothing at all.

Crypto assets don't send statements. Nothing arrives in the mail. If nobody knows to look, those crypto assets sit on the blockchain untouched, and your executor closes the estate without them.

"Vaguely" isn't much better. I knew our bitcoin existed. I couldn't have told you whether it was on an exchange, in a digital wallet on a phone, or on a hardware wallet. Your family needs three things: to know it exists, to know roughly what kind of holding it is, and to know where the instructions are. That's the minimum for any crypto estate plan.

One person knows everything, and it's all in his head

In a lot of households, one person handles the bitcoin. That's usually fine while he's here. The problem is that the whole plan lives in one memory.

Death isn't the only way that memory goes missing. An accident or an illness can leave you alive but unable to help. That's why incapacity planning matters as much as planning for crypto inheritance. A power of attorney may give someone legal authority to act for you. It won't tell her which seed phrase goes with which wallet.

Some people name a digital executor or another fiduciary to handle their digital assets. That can help. But a title doesn't come with knowledge. Whoever steps in still needs a written letter of instruction, and those steps have to come out of your head while you're around to write them.

Instructions written in your own jargon

This is the one I can describe best, because I lived it.

The first time I followed my husband's instructions alone, he sat behind me and wasn't allowed to help. I got stuck early, mostly on words he didn't notice were jargon. To him, "open the wallet" was obvious. To me, it raised questions. Which wallet? The digital wallet app? The hardware wallet? And what was I supposed to see when it opened?

You use words like seed phrase, private key, and signing every day. She may never have heard them. Before each step, say what it means in plain words. After each step, say what she should see. Our guide on how to write a bitcoin letter of instruction goes into this in detail.

Every time I got stuck, I told him how I'd have worded it, and he rewrote the step in my words. That's the fix. You can't spot your own jargon. Only she can.

The plan was written once and never reviewed

A crypto estate plan written three years ago describes the setup you had three years ago.

Things change. You update a wallet, simplify a setup, change where something is kept, or someone in the plan moves away. Each change can quietly break a step. When we simplified our setup, our instructions needed seven more rounds of testing before I could follow them again.

Put a date on the current letter of instruction so your family knows it's the one to use. Review it whenever the setup, the places, or the people change. We redo ours once a year.

Treating exchange accounts like self-custody

From my chair, bitcoin is bitcoin. From yours, you know there's a big difference in how your family reaches it.

With exchange accounts, a company is the custodian. It holds the private keys, and it has its own process for heirs. During probate, your executor will usually deal with that company, and the company decides what paperwork it needs. Giving her your password isn't the same as giving her the right to use it.

With self-custody crypto wallets, there's no custodian and no company to call. Whoever has the seed phrase and knows how to use it can move the crypto assets. Nobody can reverse a payment on the blockchain.

If you have exchange accounts and self-custody, your family needs to know which is which. Your crypto estate planning should cover all your digital assets, with separate instructions for each kind. For questions about legal authority, including incapacity planning, ask a professional where you live.

The big one: the plan has never been tested

This is the crypto estate planning mistake almost every family makes, including mine for years. The plan exists. It's written down. It may even be good. But the person who would follow it has never actually done it.

Reading it together doesn't count. When you're in the room, you fill every gap without noticing.

Sit behind her and don't help

Here's what changed things for us. I followed the instructions alone, start to finish, with my husband sitting behind me. He wasn't allowed to help.

I got stuck early. When I did, I told him what I didn't understand and how I'd have worded it. He rewrote that step. Then I started again.

Twenty rounds, then seven more

Our first version took about twenty rounds. Each round fixed something he couldn't see from his side.

After we simplified our setup, the new version took seven more. Expect it to take time, and treat every place she stops as useful. It shows you exactly which step to fix.

End with a small test payment she sends herself

A test isn't finished until something real happens. Ours ended with me sending a small test payment myself and seeing it arrive. That was the moment I believed I could do it.

Our instructions contain no secrets. They say where things are and how to check each step. The secret words are printed in red everywhere they appear, so I know when to slow down. Whether your setup uses hardware wallets or a multi-signature wallet, the test works the same way: she does it alone, on the real setup, and confirms the payment arrived.

Then you follow it too

After my test, my husband followed the instructions to the letter himself, in case he's ever the one who forgets. We redo the whole thing once a year, and a bitcoin inheritance checklist keeps each review on track.

Fixing these crypto estate planning mistakes

Most estate planning for digital assets is ordinary work, and most of these mistakes take an afternoon to fix. Keep the secrets out of the will. Tell your family what exists. Write the steps down, in her words. Date them and review them. Keep exchange accounts and self-custody apart.

The last one takes longer, and it matters most. Sit behind her, stay quiet, and let her do it.

Frequently asked questions

Is it enough to mention bitcoin in my will?

A will can say who inherits your digital assets, but it can't teach anyone how to reach them. Digital asset inheritance also needs instructions, kept separate from any secrets. For what the will itself should say, ask an estate attorney or another professional where you live.

Should seed phrases go in a will or trust?

No. A will can become public, and a will or trust is read by people who shouldn't see your seed phrase, such as staff working for the executor or trustee. The will says who. The instructions say how. The secrets stay separate.

How can she test the plan without the instructions exposing secrets?

The instructions say where things are, not what they are. She follows them on the real setup, ends with a small test payment, and confirms it arrived.

How often should we review our crypto estate plan?

Whenever the setup, the places, or the people change, and at least once a year. We redo the whole test once a year.
