If you need to serve a defendant in Argentina for a U.S. case, the country is reachable through the Hague machinery — but one of the shortcuts practitioners reach for first is off the table.
Argentina is a Hague Service country
Argentina is a party to the Hague Service Convention, so service is effected by submitting a request to Argentina's designated Central Authority. The Central Authority forwards the request to the competent court, which arranges service under Argentine law and returns proof. The documents to be served must be translated into Spanish for the request to proceed.
Service by mail is off the table
The Convention's Article 10 preserves "alternative" channels — most commonly service by postal mail, and service through a private server. Argentina objected to Article 10. That means service by postal mail or a private process server is not a valid route in Argentina, regardless of whether the defendant actually received the documents.
This matters because the Convention demands strict compliance. Defective service can void the resulting orders or judgment — even where the defendant had actual notice. A shortcut here doesn't save time; it puts the case at risk.
Plan for the timeline
Central Authority service is reliable but not fast. Transmittal, translation, court action, and the return of proof take months, not weeks. Build that into your scheduling order and your client's expectations, and start early.
What we handle
For matters in Argentina, we prepare and transmit the request package, manage the certified Spanish translation, track the request through the Central Authority, and return documented proof of service to your team — so the service holds up.
