More Than a Law Office
We are an independent Portuguese law firm specializing in legal advice to the corporate sector, investments, and real estate, as well as to private clients in a wide range of areas of law.
We position ourselves as essential partners of our clients and their businesses, supporting them in their most strategic decision making and preparing for the future. We believe in and support long-lasting relationships with our clients.
We communicate clearly, openly, proactively and forthrightly with our clients, and we work focused on achieving the desired results.
Differentiation
The knowledge and experience acquired over two decades of activity, the firmness of unshakeable founding values, honesty and respect for ethical and deontological rules, the quality of our work, the culture we implement, are the foundations that sustain the relationship we have with our clients, a relationship of trust.
We do not go where everyone else goes, we do not do what everyone else does. We dare to specialise in areas and sectors where we make a difference, for the better, contributing positively to the achievement of concrete results and the success of our clients in the areas of activity where they operate.

Message From the Founder

Antonio Osorio
Dear Friends, Clients, and Partners,
23 years ago I opened the doors to Antonio Osorio Law Office with a simple conviction: exceptional legal work should feel human, not hierarchical.
We began small and we still small. Our practice remains deliberately boutique because we believe depth trumps breadth: every matter receives the undivided attention, every client speaks directly to the lawyer handling their file, and every strategy is custom-built rather than pulled from a template.
What we do: Corporate, Investments, Real Estate, Registries & Notaries, Business Representation and Portuguese Nationality.
What we don't do: bill by minute, making the process more complicated than it already is, or take on volume just to hit revenue targets.
If you value counsel that is equal parts rigorous and relatable, let's talk.
1 Thessalonians 5:18: "Give thanks in all circumstances; for this is the will of God in Christ Jesus for you."
With gratitude for the trust you've placed in us—and anticipation for the work still ahead.
