Inheritance Planning and Wealth Protection

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.

The legal layer — without putting keys in it

• 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.
