Bitcoin estate planning: the will says who, a guide says how

Your will can leave your bitcoin to your family. It can't get them to it. That gap is where most bitcoin estate planning falls short, and I see it from the side of the person who would have to follow it.

My husband keeps our bitcoin in self-custody, and I'm not technical. For years he "explained it" and I nodded along. I couldn't have done anything with it. This article is about the two documents that close that gap. It's one part of crypto inheritance, and our full guide to bitcoin inheritance covers the rest.

Two documents, two jobs

Most estate plans have one document doing all the work. For bitcoin, and for crypto estate planning in general, that doesn't hold up.

The will says who. It names your heirs, the beneficiaries who receive your bitcoin and other digital assets, and the executor who handles the estate.

The guide says how. It walks the person who would actually act through finding each piece, using it, and checking that it worked. For self-custodied bitcoin, that's the only way anyone reaches it.

Neither can do the other's job. A will can't explain how to open a wallet. A guide can't decide who inherits. Your heirs need both, and they need to know which is which.

From where I sit, the second document is the one that's easiest to skip: written steps that someone other than you could follow.

What the will does in bitcoin estate planning

The will, or a trust, is the legal side of your estate plan. It names who inherits your crypto assets and who has authority to act. With a trust, such as a revocable living trust, the trustee manages what the trust holds. The executor or trustee acts as a fiduciary for your beneficiaries.

Some exchange accounts may offer a beneficiary designation, which can name who receives custodial bitcoin held on a cryptocurrency exchange. It does nothing for self-custody bitcoin, where no company holds the keys.

What a will can't do is reach self-custody bitcoin. No court can recreate a lost private key. A legal document can say who should have the bitcoin, but if nobody can find the keys and use them, it stays on the blockchain, out of reach.

A power of attorney is different again. It covers someone acting for you while you're alive but unable to, and it usually ends at death. Both situations need the same practical guide.

I'm not a lawyer, and none of this explains how any law works. For what your will or trust should say, ask a professional where you live.

Why secrets never go in a will

It's tempting. The will is the serious document, so the seed phrase should go there. It shouldn't.

A will passes through many hands: lawyers, office staff, relatives, the executor. In many places, it can become a public record once it goes through probate. Anyone who reads a seed phrase or the private keys can move the bitcoin, whether or not they have any right to it.

Legal ownership and technical access are two separate things. The will handles ownership. The keys handle access. Putting the keys in the will hands access to everyone who reads it.

The same goes for the guide. Our instructions contain no secrets. They say where to find things and how to check each step. The secrets themselves stay apart from both documents.

What the guide does

The guide is a letter of instruction for the person who would actually do the work. It's practical, not legal.

It starts with a digital asset inventory: a list of your digital assets by plain name, never by balance, saying whether each one is on an exchange, in collaborative custody where a company holds one key, or in a digital wallet you control. Then it takes her through each step in plain words, with a picture of every item and a checkpoint after each stage.

If your setup includes a hardware wallet, a cold wallet that keeps the keys offline, the guide should show it and name it. Whether it's a Coldcard, a Ledger, or a Trezor, the guide needs the steps for that device. Cold storage of any kind needs the same treatment: what it is, where it is, and what to do with it.

The words have to be hers. For years, I heard my husband's explanations and nodded. Familiar words didn't mean I knew what to do. The guide has to work for someone who has never done it, alone.

How the two work together

The two documents connect through a handoff. Your executor, or whoever will act, needs to know the guide exists and where to find the current copy. Your estate attorney can advise on whether and how the will should mention it.

Then comes the part most plans skip: testing the guide with the person who would use it.

The first time, I followed my husband's instructions by myself while he sat behind me, not allowed to help. It didn't take long for me to get stuck, mostly on jargon he hadn't noticed. When I got stuck, I told him how I would have said it. He rewrote the step in my words.

It finished with a small test payment that I sent myself and watched arrive. We redo it once a year.

That's what turns two documents into an estate plan, and a bitcoin inheritance plan, that works. It's also how your letter of instruction stays current. For the legal step of passing it on, see how to leave crypto in your will.

Where a professional comes in

The will, any trust, and who inherits your digital assets are legal questions. So is estate administration: who handles the estate and what authority they need. Ask an estate attorney or another professional where you live.

Bring your digital asset inventory: what's on an exchange, what's in self-custody, and that a separate guide exists. Your attorney doesn't need your seed phrase or private keys, and shouldn't have them.

The guide is different. It's practical, it's yours to write, and only the person who would use it can tell you whether it works. A lawyer can make your estate plan legally sound. Only her test run can show that your heirs can actually reach the bitcoin.

Frequently asked questions

Should I mention bitcoin in my will?

That's a question for your estate attorney. What I can say is that mentioning it isn't enough on its own. Your beneficiaries also need a guide that explains how to reach it.

Can I put my seed phrase in my will?

No. A will can become public and is read by many people. Anyone who reads the seed phrase can move self-custodied bitcoin. Keep it apart from the will and from the guide.

Do I need a trust for bitcoin?

That depends on your estate and your family, and it's a question for a professional where you live. Whatever you decide, the trustee or executor will still need a guide that's been tested.

Does my estate attorney need to understand bitcoin?

It helps if they understand the difference between owning bitcoin and being able to reach it. They don't need to know how your setup works. That's what the guide is for, and it's what your family will follow.
