Make sure your Bitcoin survives you — a plan your family can actually follow

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. (More on why that happens in the next section.)

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 — but it's the single most common way Bitcoin is lost to death. Here's the trap: many people memorize the passphrase and never write it down. When they're gone, the family finds the seed phrase, loads it, sees an empty wallet (because the real funds are behind the passphrase), and assumes there's nothing there. The money is gone forever. If you use a passphrase, it 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.

The heart of your plan is a plain-language Recovery Kit: a short document you write for your family and store with your estate papers. It doesn't need to be technical. It needs to answer, in order, "what is this, where are the pieces, and what do I do?"

Here's what to put in it:

• That Bitcoin exists — and a rough sense of how much, so your family takes it seriously.
• Which wallet app to use, by name, with a note on where to download it.
• The wallet fingerprint (XFP) — a short code, like 7A3F2C10, that the wallet shows to identify which wallet these keys belong to. It helps confirm your heir is rebuilding the right one.
• The derivation path — a short technical string (something like m/84'/0'/0') that tells the app how to find your coins inside the seed phrase. Most modern wallets use a standard path, but writing yours down removes all guesswork.
• The descriptor — for multisig, include the full descriptor text (the file that describes how your keys form the wallet). This is essential; without it, recovery can fail even with every key in hand.
• Where each backup lives — the exact location of each seed-phrase backup, each hardware wallet (the small physical device that stores a key), and, if you use one, the passphrase backup. Be specific enough that someone who doesn't live with you can walk in and find it.
• The date you last tested it — so your family knows the plan is current, not a decade stale.
• Who to call for help — the name and contact for your attorney, your collaborative-custody partner if you have one, and any trusted technical helper.

The one thing you never put in the Recovery Kit: the actual seed-phrase words or the passphrase itself. The Kit is a map to your backups, not a copy of them. Anyone who reads the Kit alone should learn how the recovery works, but should still need to physically reach your separately-stored backups to move a single satoshi. Keep the words on their metal backups, in their own secure spots; keep the Kit pointing to them.

One more test: hand the draft to a friend who knows nothing about Bitcoin and ask them to explain what they'd do. Wherever they get confused, rewrite it. You're writing for them, not for yourself.

Documentation that has never been used is the quiet failure that catches almost everyone. The fix is a rehearsal: while you're alive and well, you walk a trusted person through the whole thing as a dry run.

It's simple. Hand them the Recovery Kit — nothing else, just what they'd actually discover someday. Then watch them try to:

• find each backup and device using only the Kit's directions,
• install the right app and load the wallet as watch-only first — a mode that lets them see the balance and confirm they've got the right wallet without touching the secret keys, which is a safe way to check they're on track,
• and then move a tiny test amount to prove the full recovery works end to end.

Your job during the rehearsal is to stay quiet and only answer when the Kit is unclear — because every question they ask is a gap in your instructions. Fix each gap on the spot. Then do this again after big life changes (a new heir, a move, a change to your setup) and otherwise every few years, so the plan doesn't drift out of date.

This one habit is what separates plans that work from plans that don't. Test it now, while you can still fix what breaks.

Your Recovery Kit handles the how. A legal document handles the authority — who is officially allowed to act, and when. The common wrapper for Bitcoin is a revocable living trust: a legal arrangement you control while alive and can change anytime, that names who takes over and gives them the authority to carry out your plan.

The trust doesn't usually hold the Bitcoin directly. Instead it holds the instructions and names a trustee — often a family attorney experienced with digital assets — who has the authority to coordinate the recovery, work with your collaborative-custody partner if you have one, and act as a neutral party if family members disagree. A well-chosen wrapper also lets you keep the Recovery Kit sealed until it's actually needed, which resolves the tension between "findable by my family" and "not findable by a burglar." Name a backup trustee too, in case your first choice can't serve.

A quick, honest caveat: this is not legal advice. Estate law varies by where you live, and ordinary do-it-yourself wills often handle Bitcoin poorly. For anything beyond a small amount, sit down with an estate attorney — ideally one who has handled digital assets before.

And you don't have to assemble all of this alone. Dedicated Bitcoin-inheritance tools and services now exist specifically to help you build, store, and test a plan like this — a reasonable option if you'd rather have expert structure than start from a blank page.
