Foreign Assets Require Extra Attention

Estate Planning for Foreign Assets Requires Extra Attention 

If you own assets outside the United States — such as overseas real estate, foreign bank accounts, or international investments — your estate plan may require additional coordination. Thoughtful planning can help reduce unnecessary tax exposure, minimize administrative complications, and help ensure assets transfer according to your wishes.  

Understanding the Risk of Double Taxation

For U.S. citizens, worldwide assets are generally subject to U.S. gift and estate tax rules, regardless of where the assets are located. That can create additional complexity when another country also imposes estate, inheritance, or death taxes on the same assets.

In some situations, the same assets may effectively be taxed in more than one jurisdiction. Certain tax treaties and foreign tax credits may help offset this exposure, but availability and treatment can vary significantly by country.

Non-U.S. citizens who are considered domiciled in the United States may also be subject to U.S. estate and gift tax rules on worldwide assets. Domicile is determined by factors such as residency, intent, and long-term ties to the United States. Because these rules can be nuanced, coordination with legal and tax advisors is especially important for globally connected families.

Even families who are currently below federal estate tax exemption thresholds may still benefit from planning ahead, particularly given the potential for future legislative changes. Cross-border estate planning is often less about reacting to today’s rules and more about preparing thoughtfully for future complexity.

Consider Whether Separate Wills Make Sense

If you own foreign assets, your estate documents may need to satisfy legal requirements in both the United States and the country where the assets are held. Without proper coordination, the administration and transfer process can become more time-consuming and complicated for heirs.

In some cases, a single will may adequately address all assets. In others, separate wills may provide a more efficient solution. For example, a local-language will drafted specifically for assets held abroad may help streamline probate or administrative processes in that jurisdiction.

If multiple wills are used, coordination between U.S. counsel and local legal advisors is critical to ensure documents work together properly and do not unintentionally conflict.

A Proactive Approach Matters

Cross-border estate planning often benefits from an early and coordinated approach. Tax rules, probate procedures, reporting obligations, and legal standards can differ meaningfully across jurisdictions, making ongoing review especially important as circumstances evolve.
