NFT Inheritance for Expats in Europe: What Happens to Your Digital Collectibles When You Die Abroad

Q: Will my heirs pay Spanish inheritance tax on NFTs?

If they are resident in Spain, the Impuesto sobre Sucesiones y Donaciones applies to the worldwide estate, including digital assets, at market value on the date of death. Rates and reductions vary significantly by autonomous community. Speak to an asesor fiscal before the six-month filing deadline.

In brief: If you live abroad and hold NFTs, ENS domains or on-chain art, your heirs face two separate problems at once: a legal one (which country's succession law governs an asset that exists nowhere in particular) and a practical one (nobody can find or open the wallet). European succession law already has an answer to the first. Only you can solve the second, and it takes about an hour.

The expat who owns art that no notary can see

Consider Marieke, a Dutch product designer who moved from Utrecht to Barcelona in 2019. She has a Spanish will drawn up by a bilingual notary, a flat in Poblenou, a Sabadell account, and a Dutch pension she has not touched in years. All of it is documented.

She also has a MetaMask wallet holding eleven pieces of generative art bought between 2021 and 2024, an ENS domain she uses as her professional identity, a Tezos wallet from a collaboration with a Belgian gallery, and a handful of gaming assets on a Polygon side chain. At today's prices, that portfolio is worth somewhere between €18,000 and €40,000, depending on the week.

None of it appears in her will. None of it appears in any Spanish register. Her husband knows "she does something with crypto art" and could not name a single wallet. If Marieke died tomorrow, the flat and the pension would reach her family through the ordinary machinery of cross-border succession, slowly but reliably. The digital art would simply stop existing from her family's point of view.

This is the structural gap. Traditional estate planning works because assets are recorded somewhere a professional can look: a land registry, a bank, an insurer, a company register. NFTs are recorded on a public blockchain that nobody will think to search, under a pseudonymous address that nobody knows belongs to you.

For expats the gap widens, because the people handling your estate are often in a different country from the one you died in, working in a language that is not yours, on a file where the obvious assets already take eighteen months.

What European law actually says about NFTs and succession

The reassuring part first: your NFTs are not in a legal vacuum. They are property, and European succession law already covers them.

EU Regulation 650/2012 (Brussels IV) governs cross-border succession for residents of participating member states, and it governs the succession as a whole. It makes no distinction between a farmhouse in Galicia and a token on Ethereum. The default rule is that the law of your habitual residence at the time of death applies to your entire estate. If Marieke dies habitually resident in Spain, Spanish succession law applies to her NFTs, wherever the underlying blockchain nodes happen to sit.

The Regulation also lets you make a professio iuris: an express election, written into your will, of the law of your nationality. Marieke could elect Dutch law, in which case Dutch forced heirship (the legitieme portie, a monetary claim rather than a claim on specific assets) would apply to the value of her collection rather than the Spanish legítima. Two caveats worth knowing: Denmark and Ireland are not bound by the Regulation, and the United Kingdom never was, which is why British expats need a slightly different analysis. Our complete guide to estate planning for expats in Spain covers that election in detail, and the US-Spain guide explains why Brussels IV does not help American citizens at all.

Where NFTs sit in national civil law. Under Spanish civil law an NFT is treated as bien mueble (movable property). It falls into the estate, it is subject to the legítima if Spanish law governs, and it is subject to Spanish inheritance and gift tax (Impuesto sobre Sucesiones y Donaciones) where the heir is resident in Spain. French and Portuguese law reach a comparable result through their own categories. There is no NFT-shaped hole in the law.

Where the regulatory picture is less settled. MiCA, the EU's markets-in-crypto-assets regulation, deliberately carves out crypto-assets that are genuinely unique and non-fungible, which is why most one-of-one art sits outside its consumer-protection framework, while large fungible series may not. DAC8, the tax-transparency directive that European crypto-asset service providers began applying on 1 January 2026, reaches reportable crypto-assets held through providers, and its application to unique NFTs is narrower and still being worked through by national administrations. In Spain, Modelo 721 was designed for virtual currencies held abroad, and whether a given NFT position falls within it is a question for your asesor fiscal, not a settled matter.

The practical consequence: do not assume any authority will tell your heirs the assets exist. Regulatory reporting is not an inventory, and it was never designed to be one.

Valuation. Spanish ISD is assessed on market value at the date of death. For an illiquid NFT with three comparable sales in eighteen months, that value is a genuine question, and heirs in Spain face a six-month filing deadline that starts running whether or not they have found the wallet. Documenting your own acquisition prices, dates and marketplaces is the single most useful thing you can leave behind.

The five mistakes we see most often

1. Assuming the will is enough. A will distributes value. It does not grant access. A perfectly drafted clause leaving "all my digital assets to my spouse" is unenforceable against a hardware wallet whose PIN died with you. Ownership without access is a legal fiction.

2. Putting the seed phrase in the will. In Spain, and in most European jurisdictions, a will becomes accessible to interested parties after death and is registered centrally. A seed phrase written into a will is a seed phrase you have shared with an unknown number of people, in a document you cannot easily update when you rotate wallets.

3. Forgetting that the token and the artwork are different things. Many NFTs store only a pointer on-chain. The image itself lives on IPFS, Arweave, or a marketplace's own servers. Heirs regularly inherit a valid token that resolves to a dead link. If a piece matters to you, note where the media is actually hosted, and consider pinning or archiving it yourself.

4. Treating custodial and self-custodial holdings as the same problem. NFTs held inside an exchange or marketplace account follow that platform's terms of service and bereavement process, which usually means death certificate, proof of heirship, and a wait. Self-custodied NFTs follow no process at all: either your heirs have the keys or the assets are gone. These require completely different instructions, and platforms shut down more often than people expect.

5. Never updating the record. Wallets get rotated. Marketplaces close. Chains fork. An inventory written in 2022 and never revisited is nearly as unhelpful as no inventory, because heirs cannot tell which parts are still true.

How Sucesio complements your will

Sucesio does not replace your will, your notary or your lawyer. It solves the part they structurally cannot: making sure that when your will says "my digital assets", somebody can actually identify and reach them.

Sucesio is the map, not the vault of last resort. Concretely, for an NFT collection that means:

A living inventory. Each wallet recorded by address, chain, and the collections it holds, with acquisition dates and prices. Your notary gets an asset list. Your family gets a starting point. Your heirs' tax adviser gets the valuation history that ISD filings require.
Access instructions, not secrets. Sucesio deliberately does not hold complete seed phrases. It records where the recovery material is: which safe, which metal backup, which family member holds which Shamir share, which marketplace account uses which email. The cryptographic layer stays yours.
Context that no register captures. Which pieces were commissions, which were gifts, which you want kept rather than liquidated, which have sentimental weight beyond their floor price. This is the part of a collection that dies fastest, and the part families most regret losing.
Cross-border readiness. Your heirs may be in three countries. Sucesio's records are organised so they work alongside a Spanish notarial estate file, a Dutch verklaring van erfrecht, or a European Certificate of Succession, rather than in parallel to them.
Controlled release. Information reaches the people you designate, when the conditions you set are met. Not before.

What to do this week: a six-step plan

Step 1 — List every wallet and account. Self-custodial wallets by address and chain. Custodial marketplace and exchange accounts by platform and email. Include the ones you consider dormant; a "dead" wallet from 2021 is exactly the one nobody will find.

Step 2 — Record acquisition data. Date, price paid, currency, marketplace, transaction hash where you have it. Ten minutes per year of collecting saves your heirs a tax dispute.

Step 3 — Separate the access layer. Write down where the recovery material physically is, not what it says. "Steel plate, Bankinter safe deposit box, Barcelona branch; PIN known to my brother." Never the twelve words themselves.

Step 4 — Check the media, not just the token. For pieces you care about, confirm whether the artwork is on-chain, on IPFS with pinning you control, or on a company's server. Archive local copies of anything you would be upset to lose.

Step 5 — Align it with your will. Tell your notary that a digital asset inventory exists and where it is held. Decide, with them, whether your will should elect the law of your nationality under Article 22 of Regulation 650/2012. If you own property in Spain and spend part of the year elsewhere, ask about a power of attorney for the period before death, when incapacity, not death, is the real risk.

Step 6 — Diarise a yearly review. Fifteen minutes, once a year, on the same date as your tax filing. Add new wallets, remove closed accounts, confirm the recovery material is where you left it.

FAQ

Q: Do my NFTs pass under my will automatically? A: Legally yes, as part of your estate. Practically, only if someone can find and access them. Succession law transfers ownership; it cannot transfer knowledge you did not write down.

Q: Which country's law applies to an NFT if I live in Spain but hold Dutch nationality? A: By default, the law of your habitual residence, so Spanish law, under EU Regulation 650/2012. You can elect Dutch law in your will through a professio iuris, and that election covers your whole estate, digital assets included.

Q: Will my heirs pay Spanish inheritance tax on NFTs? A: If they are resident in Spain, ISD applies to the worldwide estate, including digital assets, at market value on the date of death. Rates and reductions vary significantly by autonomous community. Speak to an asesor fiscal before the six-month filing deadline.

Q: Should I write my seed phrase into my will? A: No. A will is not a confidential document after death, and it is difficult to update. Record the location of the recovery material separately, and keep the secret itself offline.

Q: What happens to NFTs held on a marketplace account rather than in my own wallet? A: They follow the platform's bereavement policy, which typically requires a death certificate and proof of heirship. Note the platform, the account email and the recovery method, because the account is the asset in that case.

Q: Is Sucesio a crypto wallet? A: No. Sucesio is a secure inventory and transmission tool that complements your will. It records what you own and where the access lives, so your heirs and your notary are not starting from zero.
