Inheritance Planning for Crypto Assets Across Borders

Bureaucracy Without Pain, from an international estate lawyer who has opened more seed phrases than birthday cards

Introduction: Why Your Ledger Won’t Show Up for the Reading of the Will

You can’t stick a hardware wallet in a mahogany desk and assume your heirs will “figure it out.”
Crypto assets live on blockchains that ignore borders, probate courts and, frankly, grief. Estate law does not. When clients arrive at my practice clutching a USB stick and a Maltese residency permit, the conversation usually starts with:

“If something happens to me tomorrow, how will my partner even find my coins?”

This post answers that in full, walking you through the practical, legal and tax angles of bequeathing Bitcoin, ETH, NFTs or a DeFi stash to beneficiaries who may live an ocean—and a jurisdiction—away. Consider it a map to painless bureaucracy, one SHA-256 hash at a time.

1. Why Crypto Complicates Wills

1.1 No Central Registry, No Easy Discovery

Bank accounts, brokerage portfolios and even dusty bearer bonds can be traced through statements or custodians. Your cold wallet? Not so much. Unless your heirs know the:

• Existence of the asset
• Wallet address
• Private key or seed phrase
• Relevant platforms (exchanges, DeFi protocols, staking services)

the coins might as well be burned.

1.2 Probate Courts Speak Legalese, Not Solidity

Probate procedures assume assets are registered, transferable by signature or held by an institution that recognises court orders. Smart contracts and permissionless ledgers do not comply with subpoenas. Courts can order an exchange to transfer KYC-verified holdings, but a self-custodied wallet remains immovable without the key.

1.3 Multi-Jurisdiction Tangled Web

Imagine you are tax-resident in Portugal (0% crypto gains), hold tokens on a Singapore exchange, store NFTs in a MetaMask wallet and nominate heirs in Canada. Four legal systems become relevant overnight. Conflict-of-laws rules decide which court has authority, which tax office gets first bite and whether the will itself is valid.

1.4 Volatility and Forks

Your 100 BTC could be worth a yacht or a bicycle by the time probate closes. Hard forks complicate ownership: does your will cover Bitcoin Cash? Ethereum Classic? The law usually says “yes” but only if worded properly (“all derivative assets arising from the original holdings”).

1.5 Digital Perishability

Seed phrases scribbled on paper decay or get binned by cleaners. Hardware wallets have firmware expiry. Without a robust access protocol (see Section 3), time is the enemy.

2. Choosing Jurisdictions & Entities: Where and What to Hold

Selecting the right legal “home” for your crypto can trim taxes, speed inheritance and protect privacy. Think of it as geo-arbitraging bureaucracy.

2.1 Domicile vs Residence: The Estate Law Tightrope

Most countries tax estates based on domicile (your ultimate home) rather than mere residence. You might be living the Prague dream—hopefully after reading our guide on budgeting your first 90 days in Prague—but if HMRC still views you as UK-domiciled, your heirs face up to 40 % inheritance tax on worldwide assets, crypto included.

Solution: formalise a new domicile of choice (e.g., Portugal, Malta) by demonstrating permanent ties and cutting the old ones—before the probate clock starts.

2.2 Probate-Friendly Jurisdictions

Certain locations speed up succession for digital assets:

• Singapore – Grant of probate in ~6 weeks, courts familiar with crypto exchange subpoenas.
• Switzerland (Canton Zug) – Optional “crypto will” registration, Swiss Civil Code recognises digital custody.
• Dubai DIFC – Non-Muslim wills register allows English-language wills covering global assets, zero inheritance tax.

Placing an SPV (Special Purpose Vehicle) or trust in one of these hubs can bypass slow, expensive home-country probate.

2.3 Entity Structures

1. Revocable Living Trust
   • You (the settlor) hold full control while alive.
   • On death, trustee steps in without court approval.
   • Ideal for U.S. citizens to avoid state probate.

2. Private Foundation (Panama, Liechtenstein, Nevis)
   • Foundation owns the wallets; you control the board.
   • No shares, so nothing enters probate; beneficiaries named in by-laws.
   • Strong asset-protection shield but higher upkeep.

3. Limited Liability Company (LLC) with Operating Agreement
   • Wallets listed as company property.
   • Membership interests transfer under contract law, potentially outside probate.
   • Works well for business-oriented crypto (staking pools, nodes).

4. Insurance-Wrapped Custody
   • Single-premium life policy that legally owns the coins.
   • Payout goes to heirs tax-free in many regimes; professional custodian keeps keys.
   • Premium and custody fees can be steep.

2.4 The Passport Check

Never create an entity without reading your passport country’s CFC, PFIC or anti-avoidance rules. A U.S. citizen who parks tokens in a Nevis foundation could trigger Form 3520 penalties. Japanese nationals face exit tax if they transfer unrealised crypto gains while emigrating; compare that to Taiwan’s softer stance in our Japan vs Taiwan startup visa friendliness article.

3. Secure Access Protocols: Letting Heirs in Without Letting Hackers In

A brilliant entity structure means nothing if nobody can open the digital vault. I advise clients to create a layered access protocol.

3.1 Inventory & Instruction Letter

An “Inventory & Instruction Letter” (IIL) is a plain-language document listing:

• Wallet names and types (hardware, multisig, custodial)
• Public addresses and blockchain networks
• Exchange accounts and 2FA method
• Seed phrase shard locations
• Contact info for lawyers, trustees, tech adviser

Keep the IIL physically separate from the seed phrases—think bank safe-deposit box versus fireproof home safe.

3.2 Shamir’s Secret Sharing (SSS) or Multisig

Instead of one seed phrase, split it into m-of-n shards. Example: 2-of-3 shares where any two can recreate the key. Store:

1. With independent law firm or corporate trustee
2. In a bank vault accessible to executor
3. Encrypted cloud backup with your compliance officer sibling

Alternatively, a 2-of-3 multisig wallet can allocate one key to the executor, one to the spouse, and one to an automated “dead man switch” server that releases the final signature after verifying a death certificate.

3.3 Time-Locked Smart Contracts

Ethereum and Bitcoin (via CheckSequenceVerify) allow scripts that unlock funds after X blocks or a predetermined date, automatically forwarding to beneficiary wallets. Caution: if you write the contract yourself, ensure heirs know which network an asset originally sat on (e.g., ETH vs Arbitrum) and how to claim.

3.4 Dead Man Switches & Custodial Escrow

Services like Casa Covenant or Inheriti use regular “proof-of-life” pings. Miss three monthly check-ins, and the keys transfer to designated emails or hardware devices. Always test the fail-safe—but maybe not by faking your own demise.

3.5 What Not to Do

• Don’t embed seed phrases in your will. Probate documents eventually become public record in many jurisdictions.
• Don’t rely on only cloud-based password managers; heirs may face geo-blocked or expired accounts.
• Don’t ignore firmware updates. A Trezor from 2017 without the latest patches may be unreadable in 2030.

4. Tax Implications for Heirs

4.1 Estate vs Inheritance vs Capital Gains

Different regimes tax:

• Estate tax – Levied on the deceased’s estate before distribution (e.g., U.S. federal estate tax, UK IHT).
• Inheritance tax – Levied on the beneficiary upon receipt (e.g., Japan, Belgium).
• Capital gains tax – Triggered when the asset is sold; basis may step up to date-of-death value (e.g., U.S., Canada) or remain original (e.g., Australia).

Crypto inherits the same rules as other intangible property unless statute says otherwise.

4.2 Valuation Nightmares

Exchanges quote wildly divergent prices; thin NFTs could be “worth” zero or seven figures depending on last sale. Most tax offices accept:

1. VWAP (Volume-Weighted Average Price) from top three exchanges at 00:00 UTC on date of death.
2. Third-party valuation reports (yes, you can now become a certified NFT valuer; careers everywhere).
3. For DeFi LP tokens, the underlying asset breakdown.

Document methodology; the executor needs defensible numbers if audited.

4.3 Cross-Border Double Tax

Suppose a French-domiciled founder dies holding coins in a Singapore trust, naming a German resident daughter as beneficiary. France may charge estate tax, Germany inheritance tax, Singapore none. Without a treaty, the daughter faces double tax. Solutions:

• Use double-tax treaties (rare for estate taxes, but exist: U.S.–France, U.S.–Germany).
• Credit method: one country allows a credit for tax paid abroad.
• Design irrevocable trusts or insurance wrappers excluded from estate tax.

4.4 U.S. Citizens Everywhere: The 706 Club

If you or your heir is a U.S. citizen, Form 706-NA (non-resident estate with U.S. situs assets) may still apply. Crypto held on a U.S. exchange is U.S. situs property even if you live in Bali. Flip to Kraken’s EU entity, and you might avoid it. Small details, big savings.

4.5 GST, VAT and Transfer Taxes

Transfer of NFTs sometimes triggers VAT if deemed “digital services.” Singapore and the EU both flirted with applying GST on NFT transfers. Death transfers usually exempt, but later sales by heirs are taxable events.

4.6 Charitable Remainders

Gifting crypto to a recognised charity at death can eliminate estate tax and capital gains, while your heirs receive an annuity. Popular in the U.S.; ask your CPA to simulate illustrations using IRS §7520 rates, which are ironically more volatile than Bitcoin some months.

5. Practical Roadmap: An End-to-End Plan

Below is the checklist I hand to clients after our final Zoom (yes, sometimes at 2 a.m. EU-Asia time).

1. Asset Mapping
   – List every wallet, exchange, NFT platform, DeFi position.
   – Note jurisdiction and custodian.

2. Jurisdiction Selection
   – Confirm domicile, tax residency and any treaty benefits.
   – Choose probate-efficient holding entity if needed.

3. Draft Core Documents
   – Will or pour-over will referencing a revocable trust.
   – Trust deed, foundation charter or LLC operating agreement.
   – Inventory & Instruction Letter.

4. Implement Security Layers
   – Shamir’s Secret Sharing or multisig setup.
   – Physical storage of shards; log serial numbers of hardware wallets.
   – Dead man switch activation and test.

5. Value & Document
   – Snapshot portfolio value quarterly; store PDF reports.
   – Archive smart contract addresses.

6. Inform Stakeholders
   – Brief executor, trustee, heirs and technical adviser.
   – Provide limited test access (e.g., a small sandbox wallet).

7. Review Annually
   – Update for forks, airdrops, new regulations.
   – Rebalance custody if migrating to rollups or new L2.

8. Exit Plan for Heirs
   – Pre-written SOP for liquidation or staking continuation.
   – Tax chart of jurisdictions where beneficiary might relocate (hint: BorderPilot’s relocation plan can map this automatically).

CALL-OUT: A plan is only as strong as the last time you updated it. Cryptocurrency years feel like dog years; revise annually, or at every Bitcoin halving—whichever jolts your memory first.

Common Questions I Get in Consultations

Q: Can I just leave my seed phrase with my lawyer?
A: Yes, but lawyers retire, merge, or—unpleasant truth—pass away themselves. Combine legal custody with tech redundancy.

Q: What if my heir knows nothing about crypto?
A: Name a co-executor with technical expertise or arrange a pre-paid service agreement with a reputable crypto-custody firm to onboard the beneficiary.

Q: Are NFTs treated differently from fungible tokens?
A: Legally they’re intangible personal property too, but valuation and royalty rights complicate things. Spell out licence terms in the will to avoid IP disputes.

Q: Is gifting while alive better?
A: Often, yes. Many jurisdictions have higher lifetime gift allowances or no gift tax if you survive seven years (UK). But you surrender control and expose assets to recipient divorces or creditors.

Q: My spouse and I hold a joint multisig 2-of-2. If I die, can they still move funds?
A: They’d have only one key—stuck. Switch to 2-of-3 with a neutral third key.
