If you own assets in more than one country, have heirs who live abroad, or are not a US citizen or permanent resident, your estate planning becomes significantly more complex. International estate planning requires navigating multiple legal systems, tax regimes, and treaty provisions — ideally with professional guidance from attorneys experienced in cross-border estate issues.
When International Issues Arise
International estate planning complexity arises when:
- You own real estate in another country
- You have bank or investment accounts held abroad
- You have business interests in foreign companies
- Your heirs or beneficiaries live in other countries
- You are a non-US citizen or hold dual citizenship
- You have lived and worked in multiple countries
Key Challenges in International Estates
Multiple Probate Proceedings
Real property (land and buildings) is typically subject to the laws of the country where it's located. Owning property in two countries often means two separate probate proceedings — one in each country — under each country's laws. This doubles the complexity, cost, and time.
Conflicting Legal Systems
Different countries have very different inheritance laws. Many European countries have "forced heirship" rules that prevent you from disinheriting certain family members (typically children and spouses), regardless of what your will says. If your estate plan conflicts with the local law, the local law may override your intentions.
International Tax Treaties
The US has estate tax treaties with a limited number of countries (France, UK, Germany, Canada, Australia, Japan, and a few others) that prevent double taxation of the same assets. Without a treaty, the same assets might be subject to estate tax in both countries.
FBAR and FATCA Reporting
US citizens and residents with foreign financial accounts above certain thresholds have ongoing reporting obligations (FBAR, FATCA). Failure to comply carries severe penalties. These reporting obligations continue until accounts are closed and may affect estate administration.
Non-US Citizens and US Estates
Non-Citizen Surviving Spouses
The unlimited marital deduction (which allows unlimited transfers to a surviving spouse without estate tax) does not apply to non-citizen spouses. Instead, a Qualified Domestic Trust (QDOT) can be used to defer estate taxes on assets left to a non-citizen surviving spouse. This is a significant planning consideration for international couples.
Non-Resident Aliens with US Assets
Non-US citizens who own US assets (real estate, stocks in US companies, US bank accounts) are subject to US estate tax on those assets, but with a much lower exemption (only $60,000 compared to $13.6 million for US citizens). This creates substantial exposure for non-resident aliens with US investments.
Strategies for International Estates
- Separate wills by country: Having a domestic will and one or more foreign wills (each covering assets in the respective country) can simplify administration
- Trust structures: Properly structured trusts can sometimes hold foreign assets more efficiently
- Beneficiary designations: Ensuring accounts with foreign institutions have appropriate beneficiary designations where available
- QDOT for non-citizen spouses: Essential for married couples where the surviving spouse is not a US citizen
Work With Specialists
International estate planning is genuinely specialized. General estate planning attorneys often lack the expertise needed. Look for attorneys who specialize in cross-border estate planning, and consider working with counsel in each relevant country. This is one area where general DIY tools are insufficient.
