Mi sono rivolto all' avvocato Catasti è il suo intervento è stato determinante per il calcolo delle tasse francesi relative ad una compravendita. Dopo innumerevoli tentativi esperiti in Italia, senza alcuna soluzione, l' avvocato Catasti, con competenza ed in modo celere, ha brillantemente risolto i nostri problemi. Consigliamo assolutamente di avvalersi di un professionista del suo calibro. Grazie avvocato !

Andrea has been instrumental to me as someone with dual citizenship and global income that is navigating the financial implications of living between US and France. He patiently helped me understand a complex tax ecosystem and mapped-out ideal scenarios for me. I will continue to rely on Andrea and can easily recommend him to others in similar situations.

Je me suis adressé à Maître Andrea Catasti pour une question d'impôts immobilière pour laquelle personne n'avait su donner une réponse claire. Maître Catasti a été très à l'écoute et très précis dans nos échange via email, via téléphone et via documents partagés. Il a donné une clarification très précise et professionnelle, sans cacher les incertitudes contenues dans les textes de loi et nous donner plusieurs perspectives, en précisant pour chacune un différent niveau de vraisemblance. J'ai apprécié son sérieux et sa transparence, alors que d'autres professionnels m'avaient donnés des "recettes toutes prêtes", mais sans savoir donner aucune justification (et en fait telle recettes étaient finalement incorrectes). Maître Cataste, au contraire, a produit une explication pleine de références normatives et des raisonnements très rigoureux.
