Legal Representation in Argentina: Business Structures, Small-Business Reforms and Requirements for Foreign Investors

This post is also available in:

Starting or investing in a business in Argentina does not involve a single set of legal-representation requirements. The rules depend on whether you operate independently, establish an Argentine company, register a foreign company’s branch or acquire an interest in a local business. These situations involve different legal structures, registration procedures and responsibilities.

Recent government reforms have introduced an independent-worker collaborator regime, relaunched simplified company registration and reduced certain incorporation formalities. However, simplification does not mean that every business can operate without corporate representatives, registration, or professional advice. The first step is to identify the structure that fits your activities and then establish which requirements apply.

What Does “Legal Representation” Mean in Argentina?

The term “legal representative” can describe different roles. Understanding the distinction helps business owners avoid appointing the wrong person—or assuming that one appointment covers every requirement.

A company’s legal representative

A corporate legal representative acts on behalf of a company. Their authority arises from the applicable company law, the company’s constitutional documents and the terms of their appointment.

Argentina’s General Companies Law regulates the authority and responsibilities of company administrators and representatives. A corporate representative does not necessarily have to be a practicing lawyer: the current IGJ foreign-company rules expressly distinguish registered lawyers from other representatives.

A lawyer advising or acting for the business

Hiring a lawyer is different from appointing a corporate representative. A corporate appointment authorizes a person to act for the entity within the applicable framework; it does not, by itself, constitute an appointment to provide professional legal services or handle litigation.

A business may therefore have both a corporate representative and an external lawyer, with different responsibilities.

A representative of a foreign company or overseas administrator

A foreign company registering in Argentina may need to appoint a local representative. Separately, SAS legislation sets out requirements for representatives of foreign administrators. These are distinct roles and should not be set out as interchangeable

Business Structures and Recent Reforms for Small Businesses

The current government’s measures include both new arrangements and reforms to existing structures. Do not describe every simplified procedure as a newly created type of company.

1. Independent Workers with Up to Three Collaborators: PADIC

The Trabajador Independiente con Colaboradores framework allows an independent worker to carry out a productive undertaking with up to three independent collaborators. Introduced through Law 27,742, the arrangement is registered through the Padrón de Trabajadores Independientes con Colaboradores,byas PADIC. ARCA implemented the register in inr 2024.

This framework concerns independent working relationships rather than incorporating a separate company.

Its principal requirements include:

• Registering the undertaking and collaborator relationships in PADIC before collaborators begin providing services.
• Identifying the collaborators through their CUIT numbers.
• Having each collaborator accept or reject their participation within 72 hours of notification through their electronic tax domicile.
• Maintaining no more than three independent collaborators simultaneously under the regime.
• Ensuring that the participants are registered under the applicable general tax and social-security regime or Monotributo.

The arrangement must reflect genuine independence. Collaborators may carry out activities concurrently and work with other clients or businesses. PADIC should not be treated as a mechanism for simply renaming an employment relationship.

For a small undertaking, PADIC may be relevant when the owner and collaborators genuinely operate independently. However, it does not create a limited-liability company or replace the need to assess the actual working relationship.

2. Sociedad por Acciones Simplificada: The SAS Relaunch

The Sociedad por Acciones Simplificada, or SAS, was created by Law 27,349 in 2017. It is not a new company type introduced by the current government. The current administration, however, relaunched and simplified access to SAS registration through IGJ measures announced in April 2024.

A SAS can have one shareholder or multiple shareholders. The single-shareholder option allows an entrepreneur to incorporate without adding another shareholder solely to establish the company.

The 2024 relaunch promoted procedures intended to provide registration within 72 hours, together with a CUIT and access to digital company books. This should be understood as an intended processing timeframe rather than an unconditional guarantee: the IGJ’s guidance notes that technical issues can affect processing.

A SAS remains a company with governance obligations. It must entrust its administration to one or more individuals, and organize its legal representation in accordance with the legislation and its constitutional documents.

The IGJ procedures apply within its jurisdiction in the Autonomous City of Buenos Aires. Applicants elsewhere must confirm the relevant provincial registry’s procedures.

3. September 2026 Company-Formation Reforms

IGJ General Resolution 11/2026, published on 22 September 2026, further simplified aspects of company formation and registration. It amended the IGJ framework rather than creating another company type.

The reforms include:

• Removing the general requirement for a professional prequalification opinion on incorporation, subject to applicable exceptions.
• Permitting company objects to cover multiple categories of activities without requiring those categories to be connected or complementary.
• Allowing a SAS to use an objects clause referring to “the performance of any lawful activity” or equivalent wording.
• Allowing registration of a complementary electronic headquarters alongside the physical registered office.
• Expanding accepted methods of demonstrating payment of cash capital contributions.
• Simplifying requirements for incorporation documents and subsequent corporate acts.[5][10]

These changes reduce some registration formalities. They do not remove the need to establish the company’s administration, identify who can represent it, or comply with the rules governing its chosen structure.

4. Proposed Structures Are Not the Same as Enacted Law

Parliament has also considered a broader General Companies Law reform proposal. Senate records identify it as Executive Bill PE-193/26, Message 187/26.

Proposed reforms should not be presented as available business structures solely because they have been announced or submitted to Congress. The parliamentary sources checked for this update establish the bill’s consideration, not enactment of all its proposed company categories.

Business owners should confirm the legislative position before relying on any proposed structure.

Which Arrangements Require Corporate Representation?

The following distinctions are central to choosing an appropriate route:

The correct question is therefore not simply whether every business needs a legal representative. It is which legal arrangement the business will use and which representation rules attach to it.

Foreign Companies Operating or Investing in Argentina

Argentina distinguishes between a foreign company conducting business through a local establishment and a foreign company participating as a shareholder in an Argentine company. These routes should not be confused.

Establishing a Branch or Permanent Representation: Article 118

A foreign company establishing a branch or another form of permanent representation falls within the registration framework in Article 118, third paragraph, of the General Companies Law. This includes requirements for registering and appointing a representative.

The company should determine this route before treating a shareholder registration as sufficient for its intended local operations.

Participating in an Argentine Company: Article 123

Article 123 concerns foreign companies forming or participating in Argentine companies. Registration requires corporate documentation and information about the representative and their powers.

This does not necessarily mean the Argentine company is a subsidiary. A foreign company can hold a minority investment; a subsidiary relationship involves control, which the General Companies Law addresses separately.

The representative’s role in this context should be described in relation to the foreign company’s participation in the Argentine entity—not as an unrestricted authority to conduct every type of local commercial activity.

May 2026 Changes for Foreign Companies

IGJ General Resolution 4/2026, published on 26 May 2026, amended the foreign-company provisions of General Resolution 15/2024. It took effect the following day.

Relevant changes include:

• Simplified documentation requirements for Article 118 and Article 123 registrations.
• Acceptance, in specified circumstances, of a certified consolidated version of current corporate statutes instead of every historical amendment.
• Provision for filing a foreign-company registration together with the incorporation of a local company in which it will participate, subject to conditions.
• Revised procedures relating to representatives, including registration of certain resignations.[3]

The reform maintains the distinction between participating in a local company and operating through a branch or permanent representation.

Who Can Be Appointed as a Legal Representative?

There is no single eligibility checklist that safely covers every company, administrator and foreign-company representative.

Identification, domicile and appointment requirements depend on the role and legal structure. Requirements concerning an administrator’s actual residence should also be distinguished from establishing a special address for legal notifications.

SAS Administration and Domicile Requirements

Under the SAS legislation:

• Administration is entrusted to one or more individuals, whether shareholders or not.
• At least one administrator must have an actual domicile in Argentina.
• Foreign administrators must have a CDI identification code and appoint a representative in Argentina.
• They must also establish an Argentine address where notifications can be validly served.

It is therefore inaccurate to state that every person associated with a company’s representation must satisfy an identical CUIT and permanent-residence requirement.

Representatives of Foreign Companies

The current IGJ foreign-company rules require documentation concerning the appointment, the representative’s acceptance and the establishment of a special domicile. Check these requirements against the relevant registration route.

An appointment should clearly identify the representative, their authority and the manner in which they may act.

What Powers Does a Company’s Legal Representative Have?

Applicable law, the company’s constitutional documents, and the terms of the appointment govern a representative’s authority. It should not be described simply as whatever the owner chooses to put into a private contract.

Article 58 of the General Companies Law provides that the company can be bound by acts of its administrator or representative that are not manifestly outside its corporate purpose. Internal restrictions do not necessarily prevent the company from being bound towards third parties.

This distinction matters when a business sets internal approval procedures. A rule requiring shareholder approval before a representative signs a transaction may regulate the representative’s conduct internally without necessarily preventing external legal consequences.

Article 59 also imposes duties of loyalty and diligence on administrators and representatives and provides for liability arising from breaches. Appointment therefore carries responsibilities as well as authority.

Is an Alternate Administrator Compulsory?

The answer depends on the company type and governance arrangements.

For a SAS, Article 50 requires appointing at least one alternate administrator when the company does not have a supervisory body. This is a specific statutory condition, not a universal rule that applies without qualification to every Argentine business.

The company’s documents should address the relevant appointments and how replacement arrangements operate within the applicable legal framework.

Do Simplified Procedures Mean You No Longer Need a Lawyer?

Simplifying registration does not make a corporate representative and a lawyer the same thing, nor does it eliminate every reason to obtain professional advice.

The September 2026 IGJ ed the geas a lawyer requirement for a professional prequaliseekon opinion on incorporation, subject to exceptions. That is a change to a filing requirement—not a statement that every company formation is legally straightforward.

Professional advice is particularly relevant and does not mean:

• Whether a proposed collaborator arrangement genuinely meets PADIC’s independence requirements.[
• Which company structure and governance arrangements fit the business.
• Whether a foreign company needs Article 118 or Article 123 registration.
• How to define representatives’ authority and manage the effects of internal restrictions.
• Which national rules and local registry procedures apply to the proposed registration.

A straightforward filing and a suitable legal structure are not necessarily the same thing.

Buenos Aires and Provincial Requirements

Argentina’s national company legislation provides the underlying framework, but the registry handling the application also matters.

The IGJ procedures discussed in this article concern the Autonomous City of Buenos Aires. A business incorporating or registering in a provincial jurisdiction should confirm the competent local registry’s requirements rather than assume every IGJ procedure applies nationwide.

This is especially important when relying on advertised processing times, model documents or recently simplified filing requirements.

Frequently Asked Questions

Must every small business in Argentina appoint a corporate legal representative?

No single corporate-representation requirement covers every arrangement. PADIC concerns independent individuals, while an incorporated company must organise its administration and representation under the rules applicable to its structure.

Did the current government create the SAS?

No. The SAS was created by Law 27,349 in 2017. The current government relaunched and simplified access to the structure through Law 27,349 measures in April 2024.

Can one person establish a SAS?

Yes. A SAS can have a single shareholder. The IGJ’s relaunch expressly included single-shareholder and multi-shareholder SAS companies.

Is PADIC a limited-liability company?

No. PADIC registers relationships between an independent worker and independent collaborators. It is not incorporation of a separate company.

Does every company representative have to be a lawyer?

No. A corporate representative’s role is distinct from professional legal practice. The current IGJ foreign-company rules expressly contemplate representatives who are not registered lawyers or accountants.

Can an internal contract completely prevent a representative from binding the company?

Not necessarily. Article 58 governs the company’s obligations towards third parties, and internal restrictions may not prevent external legal effects.

Can a foreign company use the same registration for every kind of activity?

The registration route must match the intended activity. Article 123 participation in an Argentine company should not be confused with Article 118 registration for a branch or permanent representation.

Choosing the Right Starting Point

Before appointing a representative or submitting a registration, establish whether the undertaking will operate through independent individuals, an Argentine company or a foreign-company structure.

Then identify the applicable registry, document the required appointments and confirm the current identification, domicile and filing requirements. Recent reforms have made some procedures more flexible, but the distinctions between these arrangements remain essential to compliance.
