Crypto Inheritance Planning

Pass on your Bitcoin without losing it to forgotten keys or legal chaos.

Short answer

Unlike bank accounts, crypto has no automatic inheritance mechanism — if your heirs can\'t access your keys, the crypto is permanently lost. Solutions: (1) multi-sig setups (Casa, Unchained) with one key held by a trusted third party, (2) documented letter of direction stored with your lawyer (never in the will itself), (3) platform beneficiary features where available (Coinbase US). Plan before death — reconstruction after is often impossible.

The problem

Traditional banks have well-established death procedures: death certificate + probate → executor gets access → funds distributed per will. Crypto self-custody has none of this infrastructure built in. If you hold BTC on a hardware wallet and nobody else has the seed phrase, your death makes that crypto permanently inaccessible. Estimates: 20-30% of all Bitcoin issued is already permanently lost, much of it to forgotten passwords, lost hardware, or insufficient documentation at time of death.

Even on regulated exchanges, inheritance is harder than traditional accounts. Most global exchanges require extensive documentation, take months, and some wallets held at the exchange (cold-storage crypto) may be difficult to claim even with proper documents.

Inheritance paths by custody type

Regulated exchange accounts

Best options:

Coinbase (US): has transfer-on-death / beneficiary features in some states. Check under account settings.
Kraken Bank (US): as a Wyoming SPDI bank, follows traditional banking inheritance procedures including POD (payable-on-death) designations.
Most other exchanges: death triggers estate process requiring documents, next-of-kin verification, death certificate, and probate. 3-12 months typical.

For exchange-held crypto, maintain a documented list of all accounts, username/email, support-contact procedures, and 2FA recovery locations.

Self-custody hardware wallet

No automatic inheritance. Options:

Shared seed phrase (simplest; lowest security). Give seed to spouse/heir, hope they don\'t pre-decease or get compromised. Not recommended for significant amounts.
Seed phrase split (SLIP-39 or Shamir): split seed into N shares requiring K to reconstruct. Distribute shares to trusted parties (lawyer, family). Higher security, more complex recovery.
Multi-sig 2-of-3 or 3-of-5: you hold majority of keys, trusted party holds one. After your death, heir + trusted party can recover.
Casa / Unchained professional services: coordinated multi-sig with professional recovery services. Annual fee, but dramatically easier heir experience.

Multi-sig via Casa or Unchained

These services specialise in inheritance planning:

Casa: 2-of-3 or 3-of-5 multi-sig. You hold 1-2 keys; Casa holds 1; you can designate a trusted party for another. Dedicated human support, recovery procedures, inheritance coordination. Annual subscription ($100-500 depending on tier).
Unchained Capital: US-regulated qualified custodian. Collaborative multi-sig with 2-of-3 keys across geographies. Estate-planning documentation integration. Strong for larger estates.

The letter of direction

Never put seed phrases in a will — wills become public in probate, exposing the seed to anyone who sees the probate records. Instead:

In your will: reference a separate letter of direction held with your lawyer or executor.
The letter of direction itself stays private and lists: exchange accounts (just names, not passwords), hardware wallet locations, multi-sig coordinator contacts, recovery procedures, step-by-step instructions for the executor.
Update the letter when anything changes (new platform, new wallet, moved storage location).
Store the letter with your lawyer in a sealed envelope, reviewed annually.

Practical framework (recommended for most users)

Inventory: list all crypto assets — which exchange, which wallet, approximate value.
Categorise: small positions (e.g., <$5k) can stay at an exchange with simple documentation. Medium ($5k-100k) use Casa-style multi-sig. Large (>$100k) use Unchained-style qualified custody with proper estate integration.
Documentation: write a letter of direction, store with lawyer, review annually.
Recovery rehearsal: at least once, walk your executor/heir through the process in a low-stakes test (e.g., recover a $10 wallet).
Legal wrapper: include crypto provisions in your will / trust. Use an estate attorney familiar with crypto.

Tax treatment

Crypto inheritance is treated similarly to other property in most jurisdictions:

US: crypto is estate-taxed at FMV on date of death (if above federal/state exemption). Heirs receive step-up basis — capital gains start fresh at the FMV at inheritance.
UK: crypto included in estate for IHT purposes at FMV on death.
Germany: Erbschaftsteuer applies with allowances per beneficiary relationship.
Valuation: which exchange\'s price? Use an average across major exchanges (Coinbase, Kraken, Binance) on date of death. Document the method.
Liquidity: if estate owes taxes in fiat but assets are in crypto, heirs may need to sell — can take time to access, potentially past tax deadlines. Plan liquidity buffer.

Consult an estate attorney + tax advisor in your jurisdiction.

Common inheritance failures

Seed phrase with no one knowing where it is — the single largest source of permanent crypto loss
Password-manager with no recovery access — executor can\'t unlock LastPass/1Password, can\'t access exchange
2FA-locked account — exchange won\'t unlock, 2FA device destroyed/lost
Seed phrase in safety-deposit box that requires the deceased\'s presence — bank procedures can take months to release
Multiple wallets across many platforms with no inventory — heirs don\'t know what exists
Trusted party pre-deceases or becomes incapacitated — recovery path broken

Frequently asked questions

What happens to my crypto when I die? +

If nobody else can access your keys or accounts, your crypto is permanently lost — estimates suggest 20-30% of all Bitcoin is already effectively lost to forgotten keys. Inheritance requires advance planning: (a) sharing access in a secure way, (b) using platform beneficiary features where available, (c) setting up multi-sig with distributed keys, (d) documenting locations and procedures in an estate plan. Without planning, even a $10M wallet becomes inaccessible.

Can I name a beneficiary on a crypto-exchange account? +

Limited options in 2026. Coinbase and some other US platforms have beneficiary/transfer-on-death features for US users; check your specific platform. Most exchanges globally do NOT have native beneficiary features — death of the account holder typically triggers an estate process that requires documents (death certificate, probate, next-of-kin verification) to unlock the account. Self-custody wallets have NO built-in beneficiary mechanism; inheritance must be engineered externally.

What is multi-sig inheritance? +

Multi-sig (multiple-signature) wallets require multiple keys to authorise transactions. Common inheritance setup: 2-of-3 multi-sig where you hold 2 keys and a trusted third party (lawyer, family member, or service like Casa) holds the third. In life: you use your 2 keys to transact. After death: the third-key holder + one of your remaining keys (held by executor via your estate plan) can recover funds. This prevents: single-point-of-failure loss, premature access by co-signers, and catastrophic loss if you forget or lose a seed.

What services help with crypto inheritance? +

Casa (casa.io) — multi-sig service with inheritance planning, dedicated human support, 2-of-3 and 3-of-5 options. Unchained Capital — US-regulated qualified custodian with collaborative multi-sig and inheritance documentation. Casanova / Safe Haven — DeFi-based inheritance smart contracts (technical). Vault12 — digital inheritance with social recovery. Trust & Will + traditional estate lawyers with crypto experience — documents the process legally within wills/trusts.

How do I document crypto assets in a will? +

Best practice: reference the assets without exposing keys. Example: "My cryptocurrency assets are held in accounts and wallets referenced in a separate letter of direction, held with [lawyer/executor name]. Executor shall follow the procedures described therein." The "letter of direction" (stored separately, updated regularly) lists: exchange accounts with support-contact protocols, hardware wallet storage locations, multi-sig coordinator contact, seed-phrase backup locations, and step-by-step recovery procedures. Never put seed phrases directly in a will — wills become public in probate.

What about digital-executor services? +

Several platforms now offer "digital executor" functionality: Trust & Will digital, Dash by Goldman Sachs (selected products), and crypto-specialised services like Casa Covenant. They act as the bridge between your estate planning and your crypto access procedures, providing audit trails and secure handoff. Fees: typically annual subscription ($100-500/year) or per-custody-service. For large crypto estates, absolutely worth it; for small positions, self-managed documentation + trusted executor is adequate.

Are crypto inheritance taxes different? +

Generally no — crypto is treated as property in most inheritance tax regimes (US estate tax, UK IHT, German Erbschaftsteuer, etc.) at FMV on date of death. The inheritor receives the crypto with a cost basis equal to the FMV at inheritance (step-up basis in the US). Crypto-specific complications: valuation on date of death (which exchange's price?), accessing the asset to pay taxes (timing issue if keys take time to recover). Consult an estate attorney familiar with crypto in your jurisdiction.
