Real estate Tier 3

ASBZ Advogados is equipped to advise on complex real estate development projects, acquisitions, financings and corporate ventures. The team also has good expertise on the litigation front. Clients include major developers and investment funds. Practice heads Marcelo Valença and Raquel de Moraes Laudanna Marinelli are both highly recommended by clients.


‘ASBZ has a team of experienced real estate lawyers that are reliable, creative and professional. They will continue to hammer away at issues until they find a solution they can recommend or simply and frankly tell you there is NO solution. In other words, you will always know with transparency if a decision can be taken or not. You never leave a deal wondering if you could have done it with an other law firm.’

‘The team has great knowledge in the area of local real estate legislation (which is extremely complex) regarding taxes, capability of foreclosing as well as clauses that will hold in a court in the event of a chapter 11.’

‘Marcelo Valença is a very experienced real estate lawyer that has done hundreds of real estate transactions which range from the simple to the highly complex. He is always willing to take on the most difficult of transactions and help the client get the deal done.’

‘Raquel Laudanna is an efficient lawyer and a great negotiator.’

Corporate and M&A Tier 4

ASBZ Advogados has seen significant growth since its establishment in 2011, and has cemented a solid reputation in the corporate sphere.

Key partners Ricardo Melaré and Gabriela Claro can draw on in-house and private practice experience, including at international firms. Gustavo Rached Taiar and associate Thiago Takuno receive praise.


The main difference between ASBZ team and other law firms is that they are all business oriented, they behave like entrepreneurs all the time. They are fast to understand the details of the negotiation, and always translate the legal terms, especially in M&A practice, to business language, so we can decide and proceed very fast in the negotiation causing no unnecessary noise to the other part of the negotiation.

It is also important to mention that the ASBZ office is completely different from other law firms; it looks like a start-up company, which makes them very agile. Lastly, all of the staff, not only the lawyers, make you feel like you are in your own company.

Gustavo Taiar is an exceptional lawyer, not only very knowledgeable but also very humble and always available.

The office is very well located in the heart of the commercial area of Sao Paulo. Very cool interior design. Doesn’t look like a law firm at all, and that is a good thing. The team is very friendly and accessible, there is no formality and they are very honest.

Gustavo Rached Taiar – very patient, he stands out bringing the most important things in the negotiation to our attention. He is very focused in our meetings, so we just need to explain one time our demands and situation. Another great thing is that the feedbacks is very fast.

Thiago Takuno – very focused, every demand that we or the deal needs, he was ready to do it, and every time it was done very well. The communication was also a great factor, highly available, by WhatsApp, e-mail or phone. Last, his technical knowledge was a huge difference to make the deal done fast.
