When an estate stretches across borders, even a straightforward inheritance can become a slow, document-heavy process. A house in one country, a bank account in another and heirs living somewhere else entirely means several legal systems may each claim a say. Understanding the main moving parts helps families ask better questions and avoid costly surprises. This article is general information only and not legal or tax advice.
Which law decides?
Countries use different connecting factors to decide which inheritance rules apply. Some look at the nationality of the person who died, others at their habitual residence, and many treat land and buildings according to the law of the place where they are located. Within the European Union, a common regulation generally links succession to the deceased's last habitual residence, while allowing a choice of the law of nationality in some cases. Outside such frameworks, the rules can overlap or even conflict, which is why the specifics of each case matter so much.
Some legal systems also include forced heirship rules, which reserve a portion of the estate for children or spouses regardless of what a will says. Heirs from countries without these rules are sometimes surprised to find them in force elsewhere.
Planning with wills
A valid will remains the clearest way to express wishes and reduce disputes. People with significant assets in more than one country sometimes prepare separate wills for each jurisdiction, written to meet local formal requirements. This approach can make probate simpler, but it has to be done carefully: a later will can accidentally revoke an earlier one if the wording is not coordinated. Keeping all documents consistent and up to date after major life events is essential.
Why specialist advice matters
Cross-border estates involve questions that general practitioners may not handle routinely. An international inheritance lawyer can explain which jurisdiction is likely to govern, how foreign documents need to be certified or translated, and how to coordinate with lawyers, notaries or courts in other countries. In many cases, advisers in each relevant country work together on a single estate.
Tax questions to raise early
Tax treatment varies enormously. Some countries levy inheritance tax on the recipient, others charge estate tax on the deceased's assets, and some have neither. The same estate may be exposed to taxes in more than one place. Points worth discussing with a qualified tax adviser include:
- whether a double taxation agreement exists between the countries involved;
- available reliefs or allowances, such as for spouses or close relatives;
- reporting obligations for foreign assets received by heirs;
- deadlines that may apply for filing and payment.
The practical steps of administration
- Gather death certificates, wills and a full list of assets and debts in each country.
- Identify which courts or authorities need to confirm the executor's or heirs' authority.
- Arrange certified translations and any required legalisation, such as an apostille.
- Close or transfer accounts, deal with property registration and settle outstanding liabilities.
- Distribute assets once all authorities and tax offices have given clearance.
Timelines depend heavily on the countries involved and on how complete the paperwork is.
Reducing friction for the family
The most helpful step anyone with international assets can take is to plan while they still can: keep an organised record of accounts and property, tell executors where documents are kept, and review arrangements with professional advisers periodically. Heirs who start the process with clear information and qualified help usually face fewer delays and far less stress.
