Jurisdiction overview

Argentina’s constitution, first written in 1853 and based on the US model provides the basis for its law. Argentina has a civil law system. 

Those who wish to practice law in Argentina must obtain a masters in law and register with a local bar association. Local lawyers are not allowed to partner with foreign lawyers, but they can employ foreign lawyers and be employed by foreign lawyers or firms. Foreign lawyers can advise on global law but are not allowed to appear in court, unless they re-qualify. The process for re-qualifying depends on the country where the lawyer obtained their original degree.

The market is largely made up of local firms though some global firms such as Baker & McKenzie and Hope Duggan & Silva have a presence in the country. Many local firms are part of larger associations or have alliances with firms in other countries.
