Why Bitcoin doesn’t inherit like money

When people think about protecting Bitcoin, they picture hackers. But for inheritance, the number-one way things go wrong is simpler and quieter: your family can't find your Bitcoin, and even if they stumble onto it, they don't know what to do with it.

Picture what your heirs actually encounter. They're grieving. They open a drawer and find a metal plate with 12 or 24 odd words stamped into it. To you, that's a seed phrase — the master backup of a Bitcoin wallet, the list of words that can restore your entire wallet on any compatible device. To them, it might look like a strange keepsake. People have thrown these away as junk.

Or they find the words, load them into some app, and see an empty wallet — so they conclude there was nothing there and give up. (The callout at the end of this lesson explains why that happens.)

So the goal of everything below is not fancier security. It's making your Bitcoin findable and followable: your family knows it exists, knows where the pieces are, and has step-by-step instructions a non-technical person can actually complete. A rock-solid wallet with no instructions is worse than a simple wallet with great ones.

How hard your Bitcoin is to inherit depends on how you set it up. Here's what each common setup means for your family, from simplest to most involved.

Single-signature (one key). This is the simplest wallet: one seed phrase controls everything. To inherit it, your heir loads the seed phrase into the right wallet app and moves the funds. Simple in theory — but only if they know what the words are, which app to use, and what to do next. That's what your written instructions are for.

Single-sig with a passphrase. A passphrase (sometimes called a "25th word") is an extra secret you add on top of the seed phrase. It creates a separate, hidden wallet. It's great security — and it's the single most common way Bitcoin is lost to death, for a reason the callout below spells out in full. What it demands of your plan: the passphrase must be backed up and inheritable, stored separately from the seed phrase, and your instructions must clearly say it exists. "It's only in my head" is not a plan.

Multisig (multiple keys). A multisig wallet needs several keys to approve spending — for example, any 2 of 3. It's very secure, but harder to inherit, because your family needs more than the keys. They also need the descriptor — a small configuration file that describes how the keys fit together to form the wallet (which keys, and the technical settings). Without the descriptor, even someone holding all the keys can struggle to rebuild the wallet. For a do-it-yourself multisig, your heirs must find every key, have the descriptor, and know how to combine signatures. That's a lot to ask of a non-technical person under stress.

Collaborative custody. This is a service where a specialized Bitcoin company holds one of your multisig keys as a partner (you still hold the others — they can never move your funds alone). For inheritance, this is the friendliest option by far. The partner already has a key, already has the descriptor, and already has the expertise. Your family's job shrinks to: contact the partner, prove identity (usually with an attorney and a death certificate), and the partner helps them recover. If your situation is at all complex, this dramatically lowers the odds your family gets stuck.

One thing to be blunt about before you build the plan. Handing someone your keys does not make the Bitcoin legally theirs. The network enforces exactly one rule — whoever can sign can spend — and has no concept of a will, an heir, or an estate. So the gap runs both ways: someone can hold your keys without being entitled to the coins, and someone can be legally entitled to them and still unable to touch a satoshi.

Nothing on this site is a legal instrument. Not this lesson, not the Recovery Kit you build next, not the plan you can save here. None of it is a will, a trust or a beneficiary designation, none of it transfers title, and none of it is legal advice. It is an access plan and deliberately only that. The next lesson covers the legal container that pairs with it — and getting that document right is a job for an estate attorney in your own jurisdiction, not for a website.
