Why due diligence in Portugal is harder than elsewhere

Portugal's Fragmented Property Registry System

Three separate government authorities each hold a different piece of the picture - and none of them automatically shares data with the others.

These three systems do not communicate with each other - problems hide in the gaps between them
What hides in the gaps
Real problems only visible when all three registries are cross-referenced together

AT looks clean
VPT reassessment risk after purchase
The Caderneta records 80m² - but the property is physically 115m². The AT never updated its record. IMI is reassessed upward after you sign.

Câmara looks clean
Active court action contesting legal ownership
The Licença de Utilização is valid - but the IRN records an acção judicial: ownership is being legally contested by a third party.
