The 7-Step Crypto Inheritance Plan for European Expats

In brief: You can put a complete crypto inheritance plan in place this week. It is not 200 pages of legal research — it is seven concrete moves. This is the short version. Each step links to a deep-dive article where you need one. Read top to bottom, do them in order, and you will be ahead of 95% of expat crypto holders in Europe.

This guide assumes you already hold crypto and live as an expat in Europe — typically Spain, Portugal or France. If you want the legal background first, start with Cross-Border Inheritance in Europe and Digital Assets Inheritance in Europe. Otherwise, start the seven steps now.

Step 1 — Inventory every wallet and exchange account

Open a blank document. List every place crypto is held: hardware wallets, software wallets, exchange accounts (Coinbase, Binance, Kraken, regulated PSANs), DeFi positions, NFTs. For each: type, provider, country of operator, approximate value range.

Do not include seed phrases, passwords or private keys in this document. The inventory is not sensitive; the access information is.

If the bulk of your holdings sits on centralized exchanges, read Your Coinbase or Binance Account After Death before continuing — exchange-held crypto has its own inheritance mechanics.

Step 2 — Decide custodial vs non-custodial per asset

For each line of the inventory, ask: is this the right custody model for my heirs, not just for me?

A crypto-literate spouse and a non-crypto-literate child need different things. A regulated CASP with a clean deceased-customer process is friendlier to a non-technical heir. A hardware wallet sovereign-secured is friendlier to a technical heir and to a long-term hold.

Most balanced plans end up mixed: long-term core in self-custody, working balances and assets being actively traded on regulated CASPs.

Step 3 — Choose your applicable succession law

EU Regulation 650/2012 ("Brussels IV") lets you elect, in your will, that the law of your nationality governs your entire succession instead of the default law of habitual residence. This matters for forced-heirship calculation on your crypto.

Two caveats worth knowing before you assume Brussels IV solves everything:

France (since 2021): French-resident children retain a droit de prélèvement compensatoire on French-located assets, even if you elect foreign law. See Crypto Inheritance Tax in France.
Spain: the autonomous-community level affects tax even when civil law is foreign. See Crypto Inheritance Tax in Spain.
Portugal: direct-line heirs are exempt from inheritance tax regardless of law election. See Crypto Inheritance and Tax in Portugal.

Step 4 — Update your will with a notary

Visit a notario, notaire, or notário. Add (or update) a clause that references the existence of crypto holdings, in approximate magnitude, and that elects your applicable succession law if relevant.

The notary needs to know that crypto exists. The notary does not need your seed phrase, your hardware wallet PIN, or your exchange password. The legal instrument and the access instrument live in different places, on purpose.

Step 5 — Set up a secure vault for access information

The vault holds what the will cannot: seeds, passwords, PINs, recovery codes. Whatever tool you pick, it should do four things:

End-to-end encryption — not even the platform operator can read your data
Trustee verification — release on confirmed death, not on a simple inactivity timer alone
EU data residency — GDPR-native handling
Multilingual heir notification — your Spanish-speaking daughter receives the email in Spanish

Sucesio is built around these four properties specifically for European expats. Any tool that meets the same bar works.

Step 6 — Designate a trustee and configure verification

Pick one person — a spouse, a sibling, a long-time friend — to act as trustee. The trustee's role is to confirm your death and trigger the release of vault contents to the named heirs. This is not the same as being an heir; it is an operational role.

Pair the trustee with an automatic verification mechanism (inactivity detection, biometric heartbeat, periodic re-confirmation). Most failures of digital legacy plans are not technical — they are the trustee not knowing they are a trustee.

Step 7 — Tell one trusted person, out loud, that the plan exists

The single highest-impact sentence you can say this month: "I have a digital legacy vault. If something happens to me, here is the name of the platform. The trustee is [name]. Contact them."

A perfect plan that no one knows about is not a plan. A merely-good plan that one trusted person knows about works. Say the sentence. Today.

Country deep dives

The seven steps are universal. The country-specific rules — forced heirship percentages, inheritance tax allowances, declaration deadlines — are not. Read the spoke for your country of residence:

Crypto Inheritance Tax in Spain for Expats — legítima, autonomous community variance, Modelo 721, AEAT.
Crypto Inheritance Tax in Portugal for Expats — legítima, direct-line tax exemption, Autoridade Tributária.
Crypto Inheritance Tax in France for Expats — réserve héréditaire, droits de succession, PACS, droit de prélèvement compensatoire.

If you split your time across two of these, read both. Forced-heirship rules interact in ways that are not intuitive.

Common questions before you start

How long does the full plan take? A focused weekend for steps 1-3 and 5-7. Step 4 (the notary visit) typically takes two to four weeks to schedule and complete. The full plan ships in under a month.

Do I need a lawyer in addition to the notary? For most expat families, no. The notary handles the will and the succession act. A cross-border lawyer is worth involving if your assets span three or more jurisdictions, if you have a business in your estate, or if your family structure is non-standard (blended families, unmarried partners with shared children).

What if I have no crypto-literate heirs at all? Lean custodial. Centralized exchanges with clean deceased-customer processes are operationally easier for a non-technical heir than a hardware wallet they have never touched. Pair with a trustee who can guide them through the release.

What if my crypto position is small — under €20,000? The same seven steps apply. The notary visit may feel disproportionate for a small position, but the access plan (steps 1, 5, 7) is non-negotiable regardless of position size. Unrecoverable crypto is unrecoverable at any value.

Sucesio is a digital legacy vault built for European expats. We handle step 5 and orchestrate steps 6 and 7. We do not hold your crypto, draft your will, or give legal advice. We sit alongside your notary-drafted will, in the same way a safe-deposit box sits alongside your bank account.

Try Sucesio for free if you want a vault built around end-to-end encryption, trustee verification, EU data residency and multilingual heir notification. Or use any tool that meets the same bar — the seven steps work either way.

Methodology

This guide was compiled in May 2026 by the Sucesio Team as the action-oriented companion to our country-specific deep dives. The seven steps are derived from observed failure modes across hundreds of expat estates: unrecorded wallets, lost seed phrases, exchange accounts frozen for lack of documentation, forced-heirship shares ignored, and trustees who did not know they were trustees. Each step exists because the absence of that step is a documented cause of inheritance failure.

This article is not legal or tax advice. For your specific situation, consult a notary in your country of residence.
