A foreign bank account does not become inaccessible simply because its owner dies, but heirs cannot usually give instructions until they prove who is entitled to act. Foreign bank account succession planning starts with that proof. The difficult part is often not the account itself. It is finding the relationship manager, locating the latest statement, obtaining the right succession document, and meeting a bank’s identity and compliance checks while the family is dealing with a death.
Good foreign bank account succession planning gives heirs a route through that process. It records each account, coordinates the will and applicable inheritance law, identifies who can speak for the estate, and asks each bank what it will require. A trust, foundation, joint account or beneficiary instruction can help in the right circumstances, but none is a universal substitute for that work. This guide gives you a practical register and a six-step plan you can use now.
Why foreign accounts complicate succession
Three separate questions arise when a family member dies with money abroad. Who inherits? That is a succession-law question. Who may instruct the bank? That depends on the account agreement, the bank’s procedures and acceptable proof of authority. What must be reported or taxed? That depends on the deceased, estate and heirs, the assets and the countries involved. The country where the bank sits does not, by itself, answer all three.
For example, the EU cross-border succession rules generally look to the deceased’s last habitual residence, subject to a valid choice of nationality law. In participating EU countries, a European Certificate of Succession can help an heir or executor prove status to a bank in another participating country. Those rules do not settle inheritance tax, and that certificate is not a universal instruction to a Swiss or Singapore bank. Families still need a coordinated review of the relevant accounts and countries.
More document work
Heirs may need a grant, inheritance certificate or other proof of authority that the bank will accept.
Missed decisions
A portfolio, loan or currency exposure can need attention while the estate is being administered.
Unclear tax exposure
Estate and heir reporting may arise in more than one country. Tax rules are separate from succession rules.
Family friction
When nobody knows the accounts or the intended decision-maker, routine bank questions can become disputes.
What heirs should do when an account holder dies
Start with the account holder’s asset register and latest statements. Identify the legal account holder, the country and banking entity, any joint holder, the relationship manager, and whether the account is a deposit, custody portfolio or company account. Then contact the bank’s estate or bereavement team and ask for its written document checklist for that specific account. Give the bank accurate information about the death; do not use the deceased person’s online credentials to move money.
Ask two separate questions: “What can the bank disclose now, and to whom?” and “What proof will the bank need before it accepts transfer or closure instructions?” An initial notification or balance confirmation may have a different evidentiary threshold from a payment instruction. In Switzerland, an inheritance certificate is normally needed to dispose of an estate account; the Swiss government’s inheritance-certificate guidance explains that obtaining one can itself take several weeks. UBS’s published procedure for Swiss-domiciled clients illustrates why bank-specific instructions matter: it distinguishes reporting a death from proving the heirs’ authority to act. Its procedure expressly covers Swiss-domiciled clients, so foreign-domiciled cases need an individual checklist.
The typical file contains a death certificate; the will, if any; a grant of probate, letters of administration, inheritance certificate or equivalent; the executor’s or heirs’ identification; and the bank’s own forms. A foreign document may need a certified translation or authentication. Ask before ordering either: an Apostille authenticates the origin of a qualifying public document under the Hague Apostille Convention; it does not validate every statement inside it, and it is not required for every document in every case.
One question that prevents avoidable delay
Ask the bank whether it will require every heir to sign, whether an executor can act alone under the document supplied, and whether any outstanding loan, mandate or restricted security changes its process. Do not assume the answer from the account label. A “joint” account, for example, may be subject to a survivorship arrangement in one country and a different inheritance analysis in another.
Which account structure helps—and what it cannot solve
The best structure is the one that fits the family’s succession law, tax position, control needs and bank’s product rules. A structure chosen only because it sounds “probate-proof” can create a new set of costs and reporting duties. Use the comparison below as a set of questions for your legal and banking advisers.
Sole personal account
Useful when: the owner wants direct control and the estate documents are clear. Check: what proof the bank needs before an executor or heirs may instruct it; whether investment mandates or borrowing need separate attention. A will identifies intended heirs, but the bank still verifies authority.
Joint account
Useful when: both people genuinely need access during life and the contract fits the intended ownership. Check: signing rights, survivorship terms, the deceased’s beneficial share and local inheritance rules. Joint title does not guarantee automatic, tax-free transfer everywhere.
Beneficiary or payable-on-death designation
Useful when: the particular account or product offers a valid designation. Check: whether the bank actually offers it for this product and jurisdiction, how to update it, and whether mandatory-heir or tax rules still apply. Do not assume an ordinary foreign current account has this feature.
Trust or foundation ownership
Useful when: there is a real family-governance or continuity need and the cost is proportionate. Check: who legally owns the bank account, trustee or council powers, succession of office-holders, disclosure and tax obligations, and potential forced-heirship claims. The structure may continue after a founder’s death, but it does not guarantee that courts, heirs or tax authorities in every country will ignore the transfer.
A Liechtenstein foundation or trust may be appropriate for a complex family, especially where ownership and management should continue beyond one person. It requires carefully drafted governing documents, competent fiduciaries, bank acceptance and advice in all relevant countries. For a simpler estate, a current will, a complete account inventory and a clearly authorized executor may do more for heirs than an expensive entity. Read our separate Swiss bank inheritance guide for the Swiss bank process, and treat any structure-specific claims there as issues to confirm with local counsel.
International tax: start with the people and assets, not a rate table
A table of national inheritance-tax percentages can be seductive and misleading. Rates change; exemptions depend on family relationship and residence; and the account’s location may matter differently from the location of its underlying securities. The practical question is which country can tax the estate, an heir or a particular asset—and whether a treaty or domestic relief applies. The EU e-Justice Portal expressly separates its succession rules from inheritance tax.
| Connection to check | Practical question for the advisers | Document to collect |
|---|---|---|
| Deceased person’s last residence, domicile and nationality | Which succession law and taxing rules may apply to the estate? | Will, residence and tax records, nationality documents |
| Each heir’s residence and citizenship | Must the heir report the inheritance or future account income locally? | Heir identity and tax-residence details |
| Account and asset location | Is the bank merely the custodian, or does an asset have its own local tax treatment? | Account and portfolio statements |
| Trust, foundation or company ownership | Who is the legal and beneficial owner, and what reporting applies before and after death? | Deeds, charter, shareholder register and bank ownership file |
| Potential relief or treaty | Could two systems tax the same transfer, and what claim must be filed? | Tax assessments, valuations and filing calendar |
Two examples show why dated rate tables fail. Swiss inheritance tax is canton-dependent, with no federal inheritance tax; residence and the type of asset matter, as the Swiss government explains. In the UK, the scope of inheritance tax for foreign assets changed from 6 April 2025 under long-term residence rules. The owner’s old “domicile” shorthand may no longer describe the current position. A cross-border estate needs a current, fact-specific calculation.
Swiss, EU and Singapore accounts: where the process differs
Switzerland. The bank will identify the persons entitled to information and to give instructions. A Swiss inheritance certificate is normally used to prove an heir’s entitlement for a Swiss-administered estate; a foreign estate may present different documents, which the bank must assess. Ask the relationship manager for the exact route before paying to translate and authenticate a large package. Our Swiss inheritance article goes deeper into the bank-facing sequence.
Participating EU countries. A European Certificate of Succession can make it easier to prove heir or executor status across those countries. The EU framework generally applies one succession law to the estate, but national tax rules remain separate. Ireland and Denmark do not participate in the EU succession regulation; the UK is outside it. A certificate designed for EU use should not be presented as automatically binding on a Swiss or Singapore institution.
Singapore. The executor or administrator may need a Grant of Probate or Letters of Administration. Yet the Singapore Judiciary says that certain joint and sole bank accounts can be dealt with without a grant if the bank’s conditions are met. That is why “all foreign accounts freeze until probate” is the wrong planning assumption. Our Singapore inheritance guide explains the local route in more detail; confirm its thresholds and document requirements with the bank and a Singapore lawyer before relying on them.
Copy this foreign account asset register
This is the document heirs need first. Keep it in a secure place the executor can find, review it after every major account or residence change, and tell the executor how to access it. Record identifiers carefully, but do not put passwords, recovery phrases or private keys into a shared spreadsheet or will.
| Field | What to record | Example (fictional) |
|---|---|---|
| Bank and legal entity | Bank name, branch or booking centre, relationship manager | Alpine Bank AG, Zurich; estate team contact on file |
| Account identity | Masked account number or reference; where the full record is stored | Portfolio ending 4821; full statement in encrypted vault |
| Owner and account form | Individual, joint, company, trust or foundation; signatories | Individual account; sole holder |
| Assets and obligations | Deposit, custody portfolio, safe, loan or guarantee; approximate value and date | Multi-currency portfolio, approx. CHF 1.2m at last review |
| Authority documents | Will, mandate, trust deed, beneficiary form and their secure locations | Will with Zurich notary; executor named |
| Bank documentation | KYC, source-of-wealth file, ownership chart and recent statements | Statement and business-sale records in vault |
| Cross-border links | Owner’s tax residences and nationalities; heirs’ countries where known | Owner resident in UAE; heirs in Switzerland and UK |
| Next action | Who contacts the bank, and what the bank has said it will need | Executor contacts estate desk; request written checklist |
The example is illustrative, not a client case. If the wealth came through a business sale, inheritance, property disposal or trading activity, place the supporting history beside the account record. A bank may ask heirs to clarify beneficial ownership or the origin of assets already on deposit. Our source-of-wealth declaration template shows how to connect the original wealth event to the assets at the current bank.
The joint account trap—and when joint ownership helps
Adding a spouse or child as a joint holder may make day-to-day access easier, but it also changes the legal and reporting facts during the owner’s lifetime. Check the account’s actual mandate: can either holder act alone; is there a survivorship clause; what portion was beneficially owned by the deceased; and can an heir challenge an attempted transfer? Do not treat “joint account” as a synonym for “passes outside the estate.”
Nor does every joint foreign account create identical U.S. reporting duties for every person named on it. The IRS FBAR guidance applies to U.S. persons with a financial interest in or signature authority over foreign accounts when the aggregate threshold is met, subject to specific exceptions. An heir or co-owner should obtain individual U.S. tax advice; a designation or structure does not itself erase reporting obligations.
A practical six-step succession plan
1. Inventory every foreign account
Use the register above. Include dormant accounts, custody portfolios, company accounts, safe-deposit boxes, loans and digital-asset custody. Reconcile the list against statements and tax records.
2. Map the law and family
Record the owner’s residence, nationality, marriage and family circumstances. Ask a qualified estate adviser which succession law applies and whether reserved shares, prior gifts or multiple wills create conflicts.
3. Ask the banks for the estate route
Confirm each account’s ownership form, survivor rights, executor requirements, acceptable documents, translation rules, loan treatment and contact point. Keep the answer with the register.
4. Choose proportionate structures
Compare a will and executor, joint title, a product-specific beneficiary instruction, or a trust/foundation where warranted. Have legal and tax advisers test the choice in each relevant jurisdiction before transferring assets.
5. Secure the evidence
Store current statements, source-of-wealth records, tax filings, deeds and identity records securely. Name the person who can find them. Keep credentials and recovery phrases in a separate protected access plan.
6. Review and explain the plan
Tell the executor and appropriate family members where the register is, who the advisers are and what the first call should be. Review annually and after a move, marriage, divorce, death, new account or major asset sale.
Common mistakes that cost heirs time
- No account inventory. Heirs cannot start with a bank they do not know exists.
- Assuming a will is a bank instruction. The bank still checks legal authority and its own forms.
- Assuming every account freezes in the same way. Joint and small-balance exceptions exist in some systems; bank terms control much of the practical process.
- Using a trust as a shortcut. A structure needs a real purpose, ongoing governance, reporting and cross-border legal review.
- Confusing succession and tax law. One law may determine who inherits while another country taxes the estate or heir.
- Ignoring digital records. Online statements, two-factor devices and digital-asset custody need a secure, lawful access plan.
- Letting documents go stale. New residence, marriage, children, a new company or a new account can make the old plan incomplete.
Who should start this planning now?
Anyone with a meaningful account outside the country where their estate will probably be administered should at least keep the register. The need is more urgent if heirs live in different countries, the account holds an investment portfolio or loan, there are children from different relationships, the owner has moved countries, or the assets sit behind a company, trust or foundation. The first useful step is modest: list the accounts and ask the bank what an executor would need.
Frequently asked questions
Do foreign bank accounts automatically freeze after death?
There is no single rule. A bank may restrict transactions while it identifies the authorized people, but treatment of joint accounts and some smaller sole accounts can differ by contract and country. Contact the bank, report the death accurately and ask what access or payments are possible pending formal estate documents.
Does a will cover an account in another country?
A valid will can set out who should inherit, subject to the applicable succession law and any protected family shares. It does not, by itself, prove to every foreign bank that a particular person may give transfer instructions. The executor or heirs may need a grant, inheritance certificate or equivalent.
Will a European Certificate of Succession release my Swiss account?
It can be used to prove status in participating EU countries. Switzerland is outside that system. Ask the Swiss bank whether and how it will recognize the certificate, and what further documents it needs.
Is an Apostille always required?
No. It is an authentication method for qualifying public documents used across participating countries. Whether a bank or authority needs it, a certified copy or a translation depends on the document, destination and case. Get the receiving institution’s written checklist first.
Is a joint account better than a beneficiary designation?
Neither is automatically better. A joint holder owns or controls the account during life under its terms; a beneficiary instruction, where a product offers one, operates differently. Ask the bank which options exist, then check ownership, reserved-heir, gift and tax effects with counsel.
Can a trust or foundation avoid probate everywhere?
No such universal guarantee exists. A properly established entity can provide continuity for assets it genuinely owns, but forced-heirship claims, tax, disclosure, bank compliance and challenges to prior transfers may still matter. Test the structure against each relevant jurisdiction.
What should a U.S. heir check?
U.S. estate, income and foreign-account reporting can be separate questions. FBAR filing depends on U.S.-person status, financial interest or signature authority, the aggregate account threshold and available exceptions. Get U.S. tax advice before assuming inherited or jointly held foreign accounts require—or avoid—a filing.
How long will heirs wait to access the money?
There is no reliable universal estimate. Timing depends on the grant or certificate process, whether the estate is contested, the number of heirs, translations, bank review and any loans or investments. Ask the bank and estate lawyer for a case-specific sequence and update it as documents arrive.
Make the first bank conversation easier for your family
Start with the account register, a current will and a conversation with each bank about its estate procedure. If you are opening a new Swiss banking relationship, ask about ownership and succession documentation during onboarding, while changes are still straightforward. Easy Global Banking can help assess the banking route and prepare the application file; legal and tax advisers should design and approve the succession plan. Discuss a Swiss bank account application.
