Estate planning becomes more complicated when assets, citizenship and tax rules extend beyond a single country. What seems straightforward on paper can quickly involve multiple jurisdictions, reporting requirements, and competing legal systems. In this episode of Celebrity Estates, Senior Editor David Lenok speaks with Martin Behn, partner at Lathrop GPM, about the estate planning challenges that arise when individuals hold assets or citizenship in more than one country. Using the recent death of actress Catherine O’Hara as an example, Martin explains how advisors must identify assets globally, determine which country’s laws apply, and account for international tax treaties. David and Martin also explore how factors like residency, citizenship and domicile influence estate taxation and inheritance outcomes. Their conversation highlights why cross-border planning often requires coordination between advisors and attorneys in different jurisdictions to help families transfer wealth effectively.
