A foreign company with an active commercial dispute in Argentina may find that the procedural rules governing its case have shifted significantly. Argentina's civil procedure regime has undergone a series of amendments affecting court filing requirements, the handling of interim injunctions, and the enforcement of judgments. Businesses that fail to adapt face a direct risk: procedural defects at the statement-of-claim stage can result in the dismissal of otherwise meritorious claims.
Argentina's amended civil procedure rules, effective from early 2025, introduce revised requirements for court filing, the conditions for obtaining an interim injunction, and the timelines governing judgment enforcement. International companies with pending or contemplated litigation must audit their procedural posture before the compliance deadline of 30 June 2025. Failure to meet the updated formal requirements can result in inadmissibility or delay of proceedings.
This alert identifies the core changes, explains which business categories are directly affected, and sets out the immediate steps that international litigants should take now.
What changed and when it takes effect
Argentina's amended civil procedure rules came into force in the first quarter of 2025. The changes affect proceedings before the federal commercial courts and the civil courts of the Autonomous City of Buenos Aires. Several provinces have indicated they will adopt parallel amendments, though their effective dates vary.
The principal changes cluster around three areas.
Court filing requirements. The updated rules mandate electronic submission of all procedural documents through the Sistema de Gestión Judicial (judicial case management system). Paper filings are no longer accepted in commercial matters above a prescribed value threshold. A statement of claim that does not comply with the new digital formatting standards will be returned without judicial consideration. This is not a correctable irregularity in most jurisdictions – in Argentina's amended system, a non-compliant filing is treated as not having been made.
Interim injunctions. The conditions for obtaining an interim injunction have been tightened. Under Argentina's civil procedure rules, an applicant must now demonstrate urgency with greater evidentiary specificity at the time of the initial application. Courts have been instructed to refuse applications that rely on generalised assertions of harm. The amendment reduces the scope for precautionary measures obtained on the basis of a bare statement of claim alone.
Judgment enforcement. The amended rules revise the procedural sequence for judgment enforcement, including cross-border enforcement of foreign awards. The documentation package required to initiate enforcement proceedings is now more extensive. Practitioners in Argentina note that enforcement applications lacking certified translations or authenticated power-of-attorney documents are being rejected at intake, rather than flagged for correction after filing.
For international companies with litigation or arbitration matters in Argentina, the combined effect of these three changes is material. A case that was procedurally sound under the prior rules may now require corrective steps before any substantive hearing can proceed.
Who is affected and which thresholds apply
The amendments apply directly to the following categories of litigants and proceedings:
- Foreign companies and individuals who are claimants or defendants in Argentine federal commercial courts
- Businesses pursuing or defending judgment enforcement proceedings, including the recognition of foreign arbitral awards
- Parties with existing proceedings where interim injunctions were obtained under the prior rules
- Any entity that has filed, or intends to file, a statement of claim in a commercial matter valued above the applicable threshold
The value threshold for mandatory electronic filing applies to claims denominated in Argentine pesos above a level set by judicial resolution. In practice, the overwhelming majority of commercial disputes brought by foreign companies will exceed this threshold. The threshold does not apply to labour matters, family law proceedings, or insolvency petitions filed under Argentina's insolvency legislation – those remain subject to separate procedural rules.
Companies with ongoing matters should verify whether their proceedings fall within the scope of the federal commercial courts or the Buenos Aires civil courts. Each court system has issued implementing guidance, and the details differ in several respects, particularly regarding the certification requirements for foreign-language documents.

What to do now: immediate actions for international companies
The compliance deadline for adapting pending proceedings to the new rules is 30 June 2025. After that date, courts will apply the amended standards without transitional accommodation. The following actions should be completed as a priority.
Audit all pending filings. Review every active matter in Argentina to confirm whether court filing has been completed in the new electronic format. Any document submitted in paper form after the effective date of the amendments should be re-filed electronically. Do not assume that prior acceptance by the court registry constitutes validation under the new rules.
Review interim injunction applications. If your company holds an interim injunction obtained under the prior, less demanding standard, assess whether it is vulnerable to challenge. Opposing parties may seek to have such orders set aside on the basis that they no longer meet the evidentiary threshold. Proactively strengthening the evidentiary record now is preferable to defending a challenge at a later hearing.
Update enforcement documentation. For any judgment enforcement or foreign award recognition proceeding, compile the full documentation package required under the amended rules before re-filing or initiating a new application. This includes certified translations of all foreign-language instruments, updated apostilles, and powers of attorney that meet Argentine authentication requirements.
Confirm local counsel mandate. Argentina's civil procedure rules require that foreign litigants be represented by a locally registered attorney in all contentious proceedings. Verify that your mandate to local counsel is current, properly authenticated, and filed with the relevant court. An expired or improperly executed mandate can suspend procedural steps at any stage.
Monitor provincial adoption. If your commercial interests extend beyond Buenos Aires, track whether the provinces relevant to your operations have adopted equivalent amendments and on what timeline. Proceedings in provincial courts may still be governed by the prior rules for a period, creating an asymmetry that can be strategically relevant in multi-forum disputes.
