If you’re an American living abroad—or splitting your life between New York and another country—your estate plan might not protect your assets the way you think it does. The rules that govern property, inheritance, and taxation shift dramatically once you cross borders. That’s why cross-border estate planning for expats isn’t just a legal formality—it’s a financial and family necessity.
This guide is for New Yorkers and U.S. citizens with homes, families, or investments overseas. You’ll learn where most cross-border plans fail, how to align your U.S. and foreign estate documents, and what treaties and choices can protect your legacy from double taxation, forced-heirship laws, and international red tape.
What Are the Most Common Estate Planning “Gotchas” for Expats?
When U.S. citizens relocate or acquire property abroad, several hidden risks can compromise even the most carefully built estate plan.
1. Dual Taxation
The United States taxes citizens on worldwide assets, no matter where they live. Meanwhile, your host country may also impose its own inheritance or succession tax. Without a coordinated plan, your estate could face tax in both jurisdictions—a preventable outcome with proper cross-border guidance.
2. Conflicting Definitions of Domicile
Each country defines “residency” and “domicile” differently. What feels like a temporary move can, in legal terms, make you appear domiciled abroad—subjecting your global estate to that country’s succession rules.
3. Unrecognized U.S. Documents
Your American will might not meet local formalities, such as translation, notarization, or registration. Power of attorney or healthcare directives created in New York often carry no weight overseas, leaving families in limbo during emergencies.
4. Forced-Heirship Rules
Many civil-law countries, including France, Spain, and Italy, reserve fixed inheritance shares for spouses or children, regardless of your will’s terms. These laws can override U.S. estate plans, forcing distributions that don’t match your wishes.
5. Ownership and Structure Issues
Countries differ in how they treat joint ownership, trusts, and community property. Some don’t recognize U.S. revocable trusts, instead treating trust assets as if owned outright by the grantor—potentially triggering unexpected tax bills.
6. Currency and Reporting Risks
Foreign accounts and investments bring U.S. reporting obligations under FATCA and FBAR. Missing a filing, even by mistake, can lead to steep penalties.

How Can You Align a U.S. Will with Home-Country Succession Laws?
The solution isn’t to duplicate your will—it’s to coordinate it.
Use Complementary, Not Conflicting, Wills
Most expats benefit from having two wills: one for U.S. assets and one for assets held abroad. Each document should clearly state that it governs only the assets in that jurisdiction to prevent accidental revocation of the other.
Verify Local Formalities
Check your host country’s requirements for witnessing, notarization, or translation. Some European nations demand that wills be executed in their official language or registered with local authorities.
Mirror Key Clauses
Executor appointments, guardianship provisions, and tax-allocation language should be consistent between documents. Contradictory definitions of “worldwide property” or “residuary estate” can create confusion and litigation across borders.
Account for Forced-Heirship Rules
If you own property in a country that enforces forced-heirship, explore planning tools such as:
- Establishing a local company or trust (if legally recognized)
- Using a marital contract or post-nuptial agreement to clarify property ownership
- Invoking the EU Succession Regulation (Brussels IV), which lets non-EU citizens choose to apply the law of their nationality to their European assets
For example, a U.S. citizen living in Paris can elect for their American law to govern their French property—potentially bypassing the country’s rigid heirship requirements.
What Treaties or Legal Tools Offer the Best Protection?
Bilateral Estate-Tax Treaties
The United States has estate-tax treaties with countries such as Canada, France, Germany, Italy, Japan, Switzerland, and the U.K. These agreements help prevent double taxation by defining which country has the taxing right over specific assets and offering credits or exemptions.
Totalization Agreements
For U.S. citizens working abroad, totalization treaties coordinate Social Security benefits and prevent dual contributions. These agreements can also influence how retirement benefits are valued for estate purposes.
Foreign Trust Recognition
Some jurisdictions, such as the U.K. and Canada, recognize U.S. trust law. Others—like France, Spain, and Brazil—do not. In those cases, alternative ownership models (corporations, partnerships, or direct title) may be safer.
Choice-of-Law Clauses
Modern estate documents can include provisions specifying which country’s law governs your estate. When paired with international regulations like Brussels IV, these clauses can streamline estate administration and reduce surprises for heirs.
How Do You Know When to Revisit Your Estate Plan?
If any of the following apply, it’s time to update your plan:
- You’ve moved abroad or gained tax residency in another country.
- You’ve acquired property or investments outside the U.S.
- You’ve married, divorced, or started a family across borders.
- You’ve established or inherited a foreign trust or corporation.
- Local tax laws or treaties have changed since your last review.

FAQs
1. Do I need separate wills for the U.S. and abroad?
Usually, yes. Having complementary wills prevents delays and conflicts in probate while respecting the legal requirements of each jurisdiction.
2. What happens if I don’t update my estate plan after moving overseas?
Your will or trust may be invalid in your new country, your estate could be taxed twice, and local laws may dictate who inherits your property.
3. How often should I review my cross-border estate plan?
Every three to five years—or immediately after moving, acquiring property abroad, or experiencing a major life change.
