Why Every Expat Needs an Asset and Liability Inventory (Not Just a Will)
In brief: A will decides who inherits. It does not tell your family what you owned, what you owed, or where to find any of it. For expats with assets spread across several countries, that missing information is what turns grief into months of detective work — and sometimes means assets are never found at all. Digital assets like crypto, passwords and online accounts make the problem sharper still, because they leave no paper trail to follow. An up-to-date inventory of your assets and liabilities, stored where your family can reach it, is the practical companion every will needs.
The Quiet Assumption That Costs Families the Most
Most people believe that if they have a will, their affairs are in order. And many expats believe the opposite version of the same comfort: that because their life feels simple, or because they have not got round to making a will, nothing much needs doing.
Both assumptions miss the same point. A will is a legal instrument that distributes what is found. It is not a map. It does not list your Spanish bank account, the brokerage account you opened in your home country fifteen years ago, the small apartment you still co-own with a sibling, the crypto on a hardware wallet in a drawer, the life insurance policy you took out when your children were born, or the three subscriptions and one mortgage still drawing money every month after you are gone.
When an expat dies, the family is left with two separate problems. The first — who inherits — is a legal question that a notary and the will can usually answer. The second — what exists and where — has no legal answer at all. It can only be reconstructed, slowly and painfully, from whatever paper, passwords, and memory the deceased happened to leave behind. For a foreign resident whose financial life is spread across two, three, or four countries, that reconstruction is the hardest part of the entire process.
This is true of every kind of asset, but it is sharpest for digital ones. A traditional asset leaves footprints — a bank sends statements, a property sits in a land registry, an insurer holds a contract — so a determined family can eventually trace it. A digital asset often leaves nothing at all, which is why it deserves a section of its own later in this guide.
What Your Heirs Actually Face When There Is No Inventory
Imagine a retired couple from Manchester who have lived near Alicante for twelve years. One of them dies. The survivor knows there is a Spanish bank account because that is where the pension lands — but is unsure whether the old UK account is still open, cannot remember which insurer holds the life policy, has no idea the hardware wallet in the office drawer holds anything at all, and discovers, three months later, that a UK premium-bond holding existed only because a letter arrives.
This is not an unusual story. It is the normal one. In the absence of an inventory, heirs become investigators. They write to banks without account numbers. They search drawers and email inboxes for clues. They pay for translations of documents they are not sure are relevant. They keep paying direct debits on services nobody can identify or cancel. And in cross-border estates, every one of these tasks is multiplied by the number of countries involved and complicated by language, time zones, and unfamiliar institutions.
The cost is not only emotional, though the emotional cost is real — searching for a dead person's financial life is a particular kind of grief that families rarely anticipate. The cost is also concrete. Dormant accounts are eventually absorbed by the state under unclaimed-asset rules. Crypto with a lost seed phrase is gone permanently — no court, no notary, and no exchange can recover it. Foreign assets nobody knows about are never declared, never inherited, never found. The will worked perfectly; it simply had nothing to point to.
Why "I Don't Have a Will" Is Not a Reason to Skip This
A large share of expats never make a will, often because cross-border legal advice feels intimidating or expensive, or because they assume their home-country will covers their Spanish assets (it frequently does not, and may even conflict with Spanish rules — a separate problem we cover in Spanish will vs foreign will for expats).
If you fall into that group, an inventory matters more, not less. When someone dies without a will (intestate), the law of the relevant country decides who inherits — but the law still cannot tell those heirs what exists. An intestate estate with no inventory is the worst of both worlds: the family neither controls the distribution nor knows what is being distributed. Building an inventory is something you can do this week, without a lawyer, without choosing beneficiaries, and without confronting any of the legal questions that may be holding you back from making a will. It is the lowest-friction, highest-value step in the entire process — and it makes the eventual will, whenever you make it, dramatically easier to draft.

The Liabilities Half Everyone Forgets
Most people who do attempt an inventory list only what they own. The debts and obligations are at least as important — and far more dangerous to leave undocumented.
In Spain, an inheritance is accepted or rejected as a whole. Heirs who accept an estate pura y simplemente (purely and simply) inherit the debts along with the assets, and can become personally liable for them. There is a protective option — accepting a beneficio de inventario (under benefit of inventory) — that limits an heir's liability to the value of the estate itself, but it requires a formal inventory of debts to be drawn up within strict deadlines. An heir who does not know what debts exist cannot make this choice intelligently, and may accept an estate that turns out to be worth less than it owes.
So your inventory should capture, alongside what you own: any mortgages and the lender, outstanding loans, tax liabilities (including the Spanish plusvalía and pending succession tax), unpaid community-of-owners fees, guarantees you have given for someone else's debt, and recurring obligations — subscriptions, insurance premiums, standing orders — that will keep drawing money until somebody knows to stop them. A clear liabilities list is what allows your family to decide, calmly and within the deadlines, whether and how to accept the estate.
What Belongs in an Expat Inventory
A useful inventory is structured, current, and stored somewhere reachable. Below is a practical starting structure for a cross-border life.
| Category | What to record | Why it matters for expats |
|---|---|---|
| Real estate | Each property, country, cadastral/land-registry reference, ownership share, mortgage lender | Co-ownership and foreign property are the assets heirs most often cannot trace |
| Bank & savings | Every account by country, institution, IBAN/number, sole or joint | Home-country accounts are routinely forgotten after years abroad |
| Investments & pensions | Brokerage accounts, funds, private and state pensions in each country | Cross-border pension inheritance is poorly understood and easily missed |
| Insurance | Life policies, the insurer, beneficiaries, policy numbers | Policies pay out only if the family knows they exist and who to contact |
| Digital assets | Crypto (type, wallet/exchange, access method), online accounts, domains | Crypto with a lost seed phrase is unrecoverable; see below |
| Passwords & accounts | Email, banking logins, cloud storage, subscriptions | The keys that unlock everything else — and the recurring charges to stop |
| Liabilities | Mortgages, loans, tax due, community fees, guarantees, recurring debits | Determines whether heirs accept the estate, and under what protection |
| People & documents | Your notary, lawyer, asesor fiscal, where the will is kept | Tells your family who to call first, and where the paperwork lives |
Digital Assets: The Part of Your Estate That Disappears First
Every category in that table matters, but one behaves differently from all the others, and it deserves its own attention: your digital assets. They are the fastest-growing part of a modern estate and, by a wide margin, the most likely to be lost completely.
The reason is that digital assets have no custodian who will eventually surface them. A forgotten bank account is, in time, traced through tax records or unclaimed-asset registers. A property cannot hide — it is on a register. But a crypto wallet announces itself to no one. A seed phrase written on a scrap of paper, or held only in your memory, is the sole key to that wealth; lose it and the funds are mathematically unrecoverable — no court order, no notary, no exchange can bring them back. Crypto held on an exchange is marginally better, but your heirs will still need to know the platform exists, hold the login, and produce a death certificate, legal translations, and proof of inheritance before the account is released — assuming they ever learn of it at all.
And digital assets are far broader than crypto. They include the email account that is the recovery route for every other login you own; online banking and investment platforms with no paper statements; cloud storage holding the only copies of irreplaceable family photographs; a PayPal, Wise, or Revolut balance; domain names and websites; an online business and its revenue; subscriptions and loyalty programmes with real monetary value; and social-media profiles that may need memorialising or closing. For an expat, these are often the most international assets of all — a wallet keyed to no country, an exchange incorporated abroad, a cloud account under a foreign provider's terms of service — which makes them the hardest for a family in another country to access through any local legal process.
This is why a digital-asset inventory is not a "nice to have" appended to the financial one — for many expats it is the part that, left undocumented, causes the largest and most permanent losses. For each digital asset, record what it is, where it lives (which wallet, exchange, or provider), and how access is meant to be obtained — stored securely, never in a plain file. The full legal and practical playbook is in how to pass on passwords and online accounts when you die and digital assets inheritance in Europe. The principle behind both is simple and unforgiving: a digital asset your family cannot access is, for every practical purpose, an asset that no longer exists.
How Sucesio Complements Your Will
A will is drafted once, signed before a notary, and locked away. Your assets and liabilities are not static — accounts open and close, properties are bought and sold, a new crypto wallet appears, a loan is paid off. The gap between a fixed legal document and a moving financial life is exactly the gap an inventory is meant to fill, and it is the gap Sucesio is built for.
Sucesio is a secure digital vault that lets you record your assets, liabilities, access information, and instructions in one structured place — and release them to the people you name, only when the right conditions are met. It does not replace your will or your notary; it sits alongside them. The will decides who inherits; Sucesio makes sure those people know what they are inheriting, where to find it, and what obligations come with it. You can keep it current in minutes whenever something changes, rather than rewriting a legal document. The aim is simple: so your family does not have to search — they find.

What to Do This Week
Start where the risk is highest, not where the paperwork is easiest. Spend twenty minutes listing every country where you hold anything — an account, a property, a policy, a pension, a wallet. That single list usually surprises people, because a life lived across borders accumulates more touchpoints than anyone remembers.
Then, country by country, fill in the categories from the table above, marking honestly where you are unsure (an unconfirmed account is still a lead your family can follow). Add the liabilities; do not stop at the assets. Note who your notary and advisers are, and where your will is held — or note that you have not made one yet, which is itself useful information for your family. Finally, store the inventory somewhere your trusted people can actually reach it at the right moment — not a desktop spreadsheet only you can open, and not an envelope nobody knows exists.
If you have already made a will, an inventory makes it work. If you have not yet made one, an inventory is the most valuable thing you can do in the meantime, and it makes the will far easier when you are ready. Either way, the document your family will be most grateful for is the one that tells them what exists and where to look.
FAQ
Q: Isn't listing my assets and passwords in one place a security risk? A: It is only a risk if stored carelessly — an unencrypted file, a shared note, a drawer. The solution is not to avoid an inventory but to store it securely: an encrypted vault that releases information to named people only under defined conditions. The far greater risk is leaving your family no information at all.
Q: Do I need a lawyer to make an inventory? A: No. An inventory is a factual record, not a legal act — you can build it yourself today. You will still need a notary or lawyer for the will itself and for the legal steps of succession, but the inventory is the groundwork that makes their job, and your family's, much easier.
Q: I have very few assets. Is this still worth doing? A: Yes — and often it matters more. Smaller estates rarely justify expensive professional searches, so anything your family cannot find is simply lost. A short, clear inventory ensures that the assets you do have actually reach the people you intend.
Q: How is this different from the inventory a notary draws up after death? A: A notarial inventory (inventario de bienes) is reconstructed after you die, from whatever can be found — which is precisely the slow, incomplete process the problem describes. Your own inventory, made while you are alive, gives that process a complete and accurate starting point instead of a blank page.
