Sorting out your disagreements


Sometimes in business things do not always go as smoothly as planned. Commercial transactions occur every second of the day, most without any problem arising. But what happens when something goes sideways? Does your company have rights that it can enforce against the other parties to the deal?

Whatever controversy your business may be facing, Castro Sammartino & Pierini may help you solve it, or litigate when all other dispute resolution methods have been unsuccessful.

When a company comes to us with a dispute, we take a common-sense approach to the problem, and explore all possible courses of action to assist and better protect our client, cost-effectively and trying to avoid litigating the case or defending it up to the highest instances available.

Castro Sammartino & Pierini involve in litigation before lower, appellate and supreme courts, at both the federal and provincial levels.

We also deal with mediations, arbitrations, labor settlement procedures, consumer settlement procedures, and administrative jurisdictional procedures before national, provincial or town agencies.

In relation to arbitration, Mario Eduardo Castro Sammartino is a commercial arbitrator of the Arbitration Panel of the Public Bar of the Autonomous City of Buenos Aires.
