The Problem

Over 800,000 foreign residents live in Portugal, many owning property. Most don't know that Portuguese forced heirship law could override their home country's will — potentially disinheriting a spouse, leaving assets to estranged children, or creating tax nightmares. The Brussels IV regulation lets them choose their national law, but this must be explicitly stated in a will.

Currently, cross-border estate planning requires hiring expensive lawyers in multiple jurisdictions (€2,000-€10,000+). Information is scattered across blogs, forums, and government websites in multiple languages. Expats either overpay for advice or, more commonly, do nothing — creating a ticking time bomb for their families.

Digital assets add another layer: crypto, online accounts, subscriptions — Portugal has no specific legislation for digital inheritance.
