The story of our legacy

Dear reader

Allow me to introduce myself. My name is Joan Gassiot Benet and I have been practising law in Barcelona for more than thirty years, specialising in urban planning and real estate law.

I am the fourth generation of a family of lawyers that began in 1903 with my great- grandfather Josep Gassiot Magret, who practised in Paseo de Gracia, 39.

The office where we are currently located, at 303 Mallorca Street in Barcelona, was opened by my grandfather, Joan Gassiot Llorens, who was admitted to the Bar in 1928.

My father, Joan Gassiot Calvet, who was admitted to the Bar in 1959, was the one who taught me the art of negotiation, honesty with the client, values among colleagues and the importance of perseverance in work and study.

Today, my son, Marc Gassiot Vila, represents the fifth generation of this lineage of lawyers.

In a world in constant change, I am deeply proud of the trust our clients have placed in us for more than a century, with many of them repeating themselves generationally. We are a family firm, where the values and experience gained from previous generations is our cornerstone. The firm is full of stories and files, which together with the current experiences, allow us to continue offering a rigorous and honest service.
