Moving countries can change the assumptions beneath an estate plan without changing a single word in the documents. Cross-border families should review not only wills and trusts, but also domicile, beneficiary forms, marital status, property ownership, and the people expected to act.
1. Which country considers you domiciled?
Domicile can be different from residence and may be determined under different tests for transfer-tax and succession purposes. More than one jurisdiction may assert an interest in the same estate.
Ask counsel to document the assumed domicile in each country and explain what facts support it. Citizenship, immigration status, permanent homes, family location, and intent can all be relevant depending on the system.
2. Will each document work where the assets are?
A single worldwide will can be efficient in some cases. In others, coordinated local wills may simplify administration. Poorly coordinated documents can revoke one another or give inconsistent directions.
Identify where real estate, companies, accounts, and personal property are legally situated. Then confirm which document controls each asset and which court or authority will recognize it.
3. Do beneficiary forms tell the same story?
Retirement accounts, insurance, transfer-on-death registrations, and jointly owned assets may pass outside a will. Compare every designation with the estate plan, including contingent beneficiaries and the consequences if a beneficiary lives in another country.
- Primary and contingent beneficiaries
- Non-U.S.-citizen spouse planning
- Minor children and guardians
- Trusts named on retirement or insurance forms
- Foreign accounts with local nominations
4. Will a trust create foreign reporting?
A trust viewed as domestic in one country may be foreign in another. Grantor, trustee, beneficiary, and asset locations can matter. Before moving, funding, distributing, or changing trustees, obtain advice on both countries’ classification and reporting.
5. Can the chosen people actually serve?
Executors, trustees, agents, and guardians may face residency restrictions, practical banking barriers, or tax consequences. Confirm that the people and institutions named are willing and able to act across borders.
End the review with an asset map, document map, and responsibility map. Those three pages are often more useful to a family in a crisis than a binder nobody can navigate.
