Your U.S. LLC is going to be a partner in an Argentine company: what the IGJ requires from the United States, in what form, and who does what

When it is required

Argentina's General Companies Law (Law 19,550) distinguishes three situations for a company formed abroad. It may carry out isolated acts and appear in court without registering (Section 118, second paragraph). If it will habitually conduct its business in Argentina — a branch, a seat, a permanent representation — it registers under Section 118, third paragraph. And if it will form or hold an interest in an Argentine company, Section 123 requires it first to prove to the registry that it was formed under the laws of its home country, and to register its organizational documents, their amendments, its enabling documentation, and the documents relating to its legal representatives.

That third case is the LLC coming in as a partner. Without the Section 123 registration, the Argentine company cannot be registered with the LLC as a member. Whether your case is Section 118 or an isolated act is the lawyer's call — not a decision made from the United States.

The current regime: RG 15/2024, amended in May 2026

The IGJ's rules are in General Resolution 15/2024. On May 26, 2026, General Resolution 4/2026 was published, in force from the following day; it repealed 29 articles of the foreign-company regime and rewrote the requirements into a single article common to Sections 118 and 123, the new Article 164. I covered the changes in detail in another post; here is what matters for assembling the package from the United States.

The five documents under Article 164, translated to an LLC

1. Certificate of good standing, no more than six months old, issued by the registry authority of the home jurisdiction. For a Florida LLC that is the Certificate of Status from the Division of Corporations; for a Wyoming LLC, the Certificate of Good Standing from the Secretary of State. Watch the six months: they are counted at the filing date in Argentina, and apostille, shipping and translation all eat into them.
2. Organizational instrument and its amendments, as copies certified by a notary or by the home registry. For an LLC that means the Articles of Organization and any amendments. The rule accepts a consolidated current text instead of each amendment, and for minor amendments a note from the representative is enough. If the lawyer also wants to include the Operating Agreement as the current governing text, it is certified the same way.
3. Resolution of the competent corporate body deciding to register and appointing the legal representative in Argentina, with their powers. In an LLC the member or the manager signs it, depending on what the Operating Agreement says. This is the document signed before a notary.
4. Written acceptance by the representative, establishing a special domicile. Signed by the representative in Argentina — with a professional seal if they are a licensed lawyer or accountant; otherwise with a notarized or digital signature.
5. Sworn statements on politically exposed person status and beneficial ownership. Also handled on the Argentine side.

Of the five, three come out of the United States (1, 2 and 3). The other two are resolved in Buenos Aires.

The form they must take

Article 34, subsection 6, of the IGJ rules sums it up: documents from abroad are filed with the formalities of their country of origin, authenticated there and apostilled, together with a Spanish version by a licensed public translator whose signature is legalized by the translators' association. In the City of Buenos Aires, where the IGJ sits, the certified translation is also mandated by Law 20,305 (art. 6).

For the resolution, Article 203 adds the detail most often forgotten: it must be signed in original by an officer of the company whose representative authority is attested by a notary. In other words, the Notary Public does not only certify that you signed: the certificate records that you sign in your capacity as member or manager of the LLC — the acknowledgment in a representative capacity provided for in Florida Statutes §117.05(13)(c). If that cannot be obtained, the rule accepts a declaration by the signer stating they hold sufficient authority, with the signature notarized. And since RG 4/2026, a resolution in digital form printed on paper is accepted, provided it is apostilled and its integrity can be verified.

Who apostilles what: the Florida Department of State apostilles Florida documents — the Certificate of Status, certified copies from Sunbiz, and anything signed before a Florida Notary Public. If the LLC is a Wyoming LLC, its certificate and Articles are apostilled in Wyoming; the resolution signed before me, in Florida. Florida is explicit: a document issued in another state goes to that state's competent authority. Florida's apostille fee is USD 10 per document and is included in my quote.

Order: issuance or signature → apostille → translation. The translator translates everything, apostille included.

Who does what

• The lawyer or notary in Argentina runs the filing: signs the professional pre-qualification opinion the rules require, prepares the resolution so it says what the IGJ needs, appoints the representative and obtains their acceptance, prepares the sworn statements, coordinates the translator and files. If the local company is being formed in the same act, they can request joint processing.
• The LLC's member or manager signs the resolution by video, from wherever they are.
• I handle the U.S. side: I request the Certificate of Status and the certified copies from the state, notarize the resolution by RON recording the capacity in which you sign, obtain the apostille and ship the package. I am a Florida Notary Public authorized for online notarization (commission HH 652310) and a Public Accountant (Argentina). And if I formed the LLC and file its taxes, the file — Articles, EIN, Operating Agreement, annual reports — is already in order: the lawyer receives a package, not a scavenger hunt.

What depends on me takes 3 to 4 business days from the moment I have the document, or from the session if a signature is involved. The state issues its certificates on its own timeline, and shipping is separate. From USD 250 per apostilled document.

The mistakes that stall the file

• An expired certificate of good standing at filing time. Request it last, not first.
• A "bare" notarized resolution, with no record of the signer's capacity or authority (Article 203).
• A notarial certificate in Spanish. Florida only apostilles with the notarial statement in English. It is done in English and translated in Argentina.
• Translating before apostilling, or asking Florida to apostille Wyoming or Delaware documents.
• The company name. The rules require it to appear exactly as in the organizational document: "My Company LLC" is not "My Company, L.L.C."

What I do not do: I do not advise on whether your LLC must register, under which section, or with which clauses. That is Argentine law and it belongs to the lawyer. I make sure the U.S. documents arrive in the form the IGJ requires.
