"Working with Theresa was a game-changer when I bought my dream house in Portugal. The property was truly one of a kind, but the deal came with a lot of complications and issues with the documentation. Theresa handled everything with care and precision, fixing the paperwork and making sure the deal went through smoothly. Beyond the legal side, she also helped with valuable advice and recommendations that made the whole process easier. I couldn't have done it without her."
"I engaged Teresa for my first Portuguese property purchase. She was thorough and helpful throughout, advising me every step of the way while overseeing key contractual details and payments in a timely manner. Thanks to Teresa, my purchase was concluded within weeks, not months, and I now have the utmost confidence in investing further in the Portuguese property market."
"Teresa was a lifesaver in securing my D7 visa for Portugal. Their expertise and clear guidance made the complex process smooth and stress-free. They were thorough, professional, and truly cared about my case. On top of that, anytime I had related questions outside of immigration - she was able to connect me with the right people. Thanks to her, I'm now happily settled in Portugal. Highly recommend!"

Theme: The Business Judgment Rule and its application in Portuguese Law
This article analyzes the origin and evolution of the Business Judgment Rule in the USA - based on the case Percy v. Millaudon (1829) - and its impact on North American jurisprudence.
We study the introduction of this rule in Portuguese Law in 2006, specifically in article 72, paragraph 2, of the Commercial Companies Code, and its articulation with the duties of care and loyalty provided for in article 64.
The article draws a parallel between the two legal systems and discusses the adoption of this doctrine in the national context.
