A short film for module 6 of Bitcoin Essentials: the two ways an inheritance plan fails, too secret for heirs to find or too exposed to keep from thieves; multisig as the structure, with keys held by different people so no one spends alone and no single loss strands the coins; backups on metal or paper in different places, with the wallet descriptor beside each; a will, which others can read after probate, that says where things are and who helps but never the seed words; a separate letter of instruction; a practice recovery with a small amount and someone technical the heirs can trust; the honest cost, that a simpler plan you will keep beats a perfect one you won't; and the contrast with fiat currency in a bank, a claim heirs must ask the bank to release. It loops while on screen; use Pause to stop it. Turn on Narration to hear it explained aloud. A transcript follows.

  1. Bitcoin Essentials · Module 6 of 9Bitcoin Inheritance Planning. Bitcoin has no account recovery and no bank to call. If you are the only person who can reach your coins, they go with you. A plan keeps them secure while you live and reachable by your heirs after you.
  2. Two ways to failAn inheritance plan has two opposite ways to fail. Too secret, and your heirs never find the keys: the coins are lost for good. Too exposed, and the plan itself leaks, and someone takes the coins while you are still alive. A good plan lets no single document, person or place spend the coins, and no single loss strand them.
  3. 2-of-3 multisigMultisig is the structure for it. A 2-of-3 wallet needs two of three keys to spend, and the keys can sit with different people: you, an heir, someone you trust. No one of them can spend alone, and no single lost key strands the coins. Multisig has risks of its own, said plainly in the Multi-sig Basics module: lose the descriptor, or two keys of three, and the coins cannot be spent.BIP 11, “M-of-N Standard Transactions” (Gavin Andresen, 2011)BIP 380, “Output Script Descriptors General Operation” (Pieter Wuille and Ava Chow, 2021)
  4. Backups that last decadesThe backups have to last decades. Write each seed phrase by hand on metal or paper, never in a file or a photo: metal survives the fire and flood that paper may not. Keep the backups in different places, so no single disaster reaches two. And keep a copy of the wallet descriptor with each one, because the seeds alone will not rebuild a multisig wallet.BIP 380, “Output Script Descriptors General Operation” (Pieter Wuille and Ava Chow, 2021)
  5. The willA will is read by other people. In England and Wales, once probate is granted, the will joins the probate records, and a copy can be ordered from them; other countries have their own rules. So the will points, and never holds keys: it says that bitcoin exists, where the pieces are, who inherits and who can help. Never the seed words.GOV.UK, “Search probate records for documents and wills (England and Wales)”
  6. A letter of instructionBeside the will, a letter of instruction, kept separately and private: the steps to recover the coins in plain words, and who to call. The key material stays apart from it again, so no single document is enough to spend.
  7. A practice recoveryThe commonest failure is not technical: it is an heir who has never held bitcoin. So walk your heirs through a practice recovery with a small amount, while you are here to answer their questions.
  8. Someone they can trustName someone technical your heirs already know and trust, to help them through it. And teach them the one rule that stops most thefts: no genuine helper will ever ask for the seed words.
  9. A plan you will keepThis takes real effort: a plan has to be made, rehearsed and kept up to date as life changes. Be honest about what you will maintain. A simpler plan you will actually keep beats a perfect one you won't.
  10. Fiat currency and bitcoinFiat currency in a bank is a claim, not money in your hands: in the Bank of England’s account, a deposit is a record of what the bank owes you. Your heirs must ask the bank to release it, on its process. Bitcoin is no one’s claim: it passes on through the structure and the people you chose. Few prices are set in bitcoin yet, and keeping it safe takes care, but the plan is yours to make.McLeay, Radia and Thomas, “Money creation in the modern economy”, Bank of England Quarterly Bulletin 2014 Q1, p. 16
  11. The Bitcoin TransitionSecure now, reachable later. Fiat waits on the bank. Bitcoin follows your plan.

Self-custody solves theft and censorship, and creates exactly one new problem: if you are the only person who can access your bitcoin, then the day you die, it dies with you. There is no court order, no customer service escalation, and no locksmith. An estimated several million bitcoin are already unreachable forever — hard drives in landfills, seed phrases never written down, plans never made. Every one of those losses was preventable. This module prevents yours.

The tension: secure now, accessible later

An inheritance plan must survive two opposite failure modes. Too secret, and your heirs never find the keys — the bitcoin is lost. Too exposed, and the plan itself becomes the attack surface — instructions or key material leak, and the bitcoin is stolen while you are alive. Good design threads the needle: no single document, person, or location should be sufficient to spend your coins, and no single loss should be sufficient to strand them.

Multisig: the inheritance-grade structure

A multi-signature wallet requires several keys to authorise a spend — commonly two of three. For inheritance this is the cleanest structure available:

  • No single point of failure: one key lost, damaged, or stolen does not lose the funds.
  • Distributed trust: keys can sit with you, a spouse, a lawyer, or a collaborative-custody service — and no single holder can act alone.
  • A built-in succession path: heirs plus a designated co-signer reconstruct spending authority without any one party ever holding everything.

Collaborative-custody services build exactly this for families and can act as the professional co-signer with inheritance procedures on file. A self-built two-of-three with well-separated keys achieves the same properties for those who prefer no counterparty.

Storage that survives decades

  • Metal, not paper: seed phrases stamped into steel survive fire and flood; paper and ink do not, and digital files fail in both directions — losable and stealable at once.
  • Split locations: backups in separate secure places, so no single disaster erases the plan.
  • Test the recovery: a plan that has never been rehearsed is a hope, not a plan. Walk through recovery with the people involved, using a test wallet.
  • Never put seed phrases in a will. Wills become public documents in probate; a will containing key material is a published invitation to theft.
  • Instead, the will points: it identifies that bitcoin exists and names who inherits it, while sealed instructions held by an executor or in a vault explain how — with the key material stored separately again.
  • Trusts can hold bitcoin governance formally: the trust defines who may access what and when, while the keys themselves stay in the multisig structure, not in a legal filing.

Prepare the people, not just the keys

The most common failure in bitcoin inheritance is not technical. It is an heir who has never held bitcoin, does not know what a seed phrase is, and panics — or trusts the first 'recovery expert' who offers to help. The knowledge transfer is part of the estate. Teach your heirs the basics now: what self-custody means, how the wallet works, what no legitimate helper will ever ask for. This course exists for exactly that handoff.

Action steps

  1. Write the one-page recovery guide for your heirs today — what exists, where the pieces are, who to involve.
  2. Upgrade significant holdings to a two-of-three multisig with keys in separate locations.
  3. Back up every seed phrase on metal, split across locations, and rehearse the recovery once a year.
  4. Have your will reference the plan without containing any key material — and brief your executor.
