ESTABLISHMENT OF FOREIGN-INVESTED ENTERPRISES IN VIETNAM (FDI ESTABLISHMENT) 2026: THE PROCESS AND PRACTICAL ISSUES OF CONSULAR LEGALIZATION OF FOREIGN DOCUMENTS FOR USE IN VIETNAM
When foreign investors establish a foreign-invested enterprise in Vietnam, numerous documents issued by foreign authorities must be submitted as part of the investment registration dossier. However, before these foreign-issued documents may be recognized and accepted by Vietnamese competent authorities, they are generally required to undergo consular legalization or qualify for an applicable exemption under Vietnamese law or an international treaty. Consequently, consular legalization has become one of the most important legal procedures affecting the preparation of investment dossiers involving foreign investors, foreign organizations, and overseas-issued corporate documents.
The consular legalization process serves as a mechanism through which Vietnamese authorities verify the authenticity of the signature, seal, and official capacity of the foreign authority issuing a document. Although this procedure does not certify the substantive accuracy of the document itself, it enables Vietnamese authorities to recognize the document as legally valid for administrative and investment-related purposes. Failure to complete the required legalization procedures may result in the rejection of the investment dossier, requests for supplementary documentation, or significant delays in obtaining the Investment Registration Certificate ("IRC") and other investment licenses.
In practice, foreign investors frequently encounter various difficulties throughout the legalization process, including differences in legalization procedures among jurisdictions, prolonged processing times, incomplete authentication chains, inaccurate Vietnamese translations, and uncertainty regarding documents that may qualify for legalization exemptions. These practical issues often increase the overall timeline and administrative burden associated with establishing a foreign-invested enterprise in Vietnam, particularly where multiple foreign-issued documents must be prepared simultaneously.

I. Legal framework governing consular legalization of foreign documents
The use of foreign-issued documents in investment procedures in Vietnam is governed by a comprehensive legal framework designed to ensure the authenticity and legal validity of documents originating from foreign jurisdictions. The principal legal basis includes the Law on Investment 2025, Decree No. 96/2026/NĐ-CP detailing and guiding the implementation of the Law on Investment, together with Vietnamese regulations governing consular certification and consular legalization and other relevant implementing regulations. In addition, Vietnam's obligations under various “international treaties”, bilateral agreements, and conventions concerning the recognition of official documents may also affect the legalization requirements applicable to certain foreign-issued documents.
The primary purpose of consular legalization is to enable Vietnamese competent authorities to recognize the legal authenticity of documents issued by foreign governmental agencies, organizations, or institutions. Through this procedure, the competent diplomatic or consular authorities certify the authenticity of the signature, official seal, and capacity of the person signing the document. Importantly, consular legalization does not verify the substantive accuracy or legal contents of the document itself; rather, it confirms that the document has been lawfully issued by the appropriate authority in the country of origin.
An important legal principle underlying the recognition of foreign-issued documents is that documents created outside Vietnam generally do not possess automatic legal validity for administrative use within Vietnamese territory. Unless an exemption applies under an international treaty or the principle of reciprocity recognized by Vietnamese law, foreign documents must ordinarily complete the prescribed authentication and consular legalization procedures before they may be submitted to Vietnamese authorities. Depending on the nature of the document, investors may also be required to obtain certified Vietnamese translations and complete notarization or certification procedures after legalization.
Accordingly, consular legalization maintains a direct and significant relationship with the investment licensing process, particularly during the application for an Investment Registration Certificate ("IRC") and, where applicable, an Enterprise Registration Certificate ("ERC"). Corporate documents such as Certificates of Incorporation, Business Registration Certificates, Articles of Association, Board Resolutions, Powers of Attorney, and audited financial statements frequently require legalization before they may be accepted by the licensing authority. Where required legalization procedures have not been completed, the competent authority will generally request the investor to supplement the dossier before continuing its examination, thereby extending the licensing timeline.

II. Consular legalization procedures for foreign documents
The consular legalization process generally applies to a wide range of foreign-issued documents that are intended to be used during investment and enterprise registration procedures in Vietnam. Documents commonly requiring legalization include Certificates of Incorporation, Business Registration Certificates, Articles of Association, Board Resolutions, Powers of Attorney, audited financial statements, bank account balance confirmations, and various other corporate or financial records submitted by foreign investors. Depending on the characteristics of the investment project, additional documents such as professional licenses, certificates of good standing, tax certificates, or project-specific approvals may also require legalization before they can be accepted by the competent Vietnamese authorities.
The legalization procedure generally begins in the country where the document is issued. Before a document may be presented to the Vietnamese diplomatic authorities, it is ordinarily required to undergo authentication by the competent authority of the issuing jurisdiction. The specific authentication authority varies among countries and may include the Ministry of Foreign Affairs, the Ministry of Justice, a notarial authority, or another designated governmental agency responsible for certifying official documents. Once the document has been properly authenticated, it is then submitted to the Vietnamese Embassy or Consulate located in that country for consular legalization. Through this procedure, the Vietnamese diplomatic mission certifies the authenticity of the signature, seal, and official capacity appearing on the authenticated document, thereby enabling Vietnamese authorities to recognize it for administrative purposes.
Following completion of consular legalization, foreign-language documents generally must be translated into Vietnamese before being submitted to the licensing authority. The translation should accurately reflect the contents of the legalized document and is typically required to be notarized or certified in accordance with Vietnamese regulations. However, investors should recognize that not every foreign-issued document must necessarily undergo consular legalization. Certain documents may be exempt from legalization where such exemption is provided under an applicable international treaty to which Vietnam is a contracting party or pursuant to reciprocal arrangements recognized by Vietnamese law.
From a practical perspective, the overall duration of the consular legalization process depends upon several factors, including the procedures of the issuing country, the workload of the competent authentication authority, the processing time of the Vietnamese diplomatic mission, and the subsequent translation and notarization procedures in Vietnam. In many cases, preparing legalized corporate documents may require several weeks or even longer where multiple authorities are involved. Investors should therefore avoid treating legalization as a last-minute administrative formality. Instead, legalization should be incorporated into the overall investment timetable from the outset of the project.

III. Documents subject to legalization and common legal requirements
A wide variety of foreign-issued documents submitted during the establishment of a foreign-invested enterprise in Vietnam are generally subject to consular legalization before they may be accepted by the competent licensing authority. Among the most important corporate documents are the Certificate of Incorporation or Business Registration Certificate, which establish the legal existence and registration status of the foreign investor, together with the company's Articles of Association, Charter, or equivalent constitutional documents that describe the investor's organizational structure and governance framework. Where the investment project requires formal approval under the investor's internal corporate procedures, a Board Resolution, Shareholders' Resolution, or another corporate decision authorizing the investment must also be prepared. In addition, if the investor appoints a representative, law firm, or consultant to conduct the investment procedures in Vietnam, a properly executed Power of Attorney authorizing such representative is typically required.
In addition to corporate records, various financial documents are commonly subject to legalization as part of the investment registration dossier. These include bank account balance confirmations, bank statements, audited financial statements, parent company financial statements, financial guarantees, and other documentary evidence demonstrating the investor's financial capability. Such documents allow the licensing authority to assess whether the investor possesses sufficient financial resources to implement the proposed investment project and contribute the registered charter capital. Depending upon the investment structure, additional supporting documents such as parent company commitment letters or financing agreements may also be requested.
Another important consideration concerns the validity period of legalized documents. Although Vietnamese legislation does not establish a universal period of validity applicable to every category of foreign-issued document, licensing authorities generally expect the submitted documents to accurately reflect the investor's current legal and financial status at the time of filing the application. Consequently, financial statements, bank confirmations, powers of attorney, corporate resolutions, and other time-sensitive documents should be prepared sufficiently close to the submission date to avoid questions regarding their reliability or relevance. Investors should also recognize that legalization itself does not permanently extend the validity of a document; rather, the underlying document must remain legally effective when presented to the Vietnamese authorities.

IV. Practical issues encountered during the legalization process
Although the legal procedures governing consular legalization are relatively well established, foreign investors frequently encounter various practical difficulties when preparing foreign-issued documents for use in Vietnam. One of the most common issues involves an incomplete authentication chain, where the document has not been properly authenticated by the competent authority in the country of origin before being submitted for legalization by the Vietnamese diplomatic mission. In many jurisdictions, documents must first pass through one or more domestic authentication procedures before they become eligible for consular legalization. Failure to complete any required step may result in the Vietnamese diplomatic authority refusing to legalize the document, thereby delaying the preparation of the investment dossier.
Another frequently encountered difficulty concerns inconsistencies arising during the translation process. After foreign-issued documents have been legalized, they generally require translation into Vietnamese before submission to the licensing authority. In practice, translation errors involving company names, registration numbers, legal representatives, dates, financial figures, or legal terminology are not uncommon. Even minor discrepancies between the original document and its Vietnamese translation may cause the licensing authority to question the accuracy of the investment dossier and request corrected translations.
Practical complications also arise from misunderstandings regarding international treaty exemptions and differences in legalization procedures among jurisdictions. Some investors mistakenly assume that all foreign-issued documents are exempt from legalization because their home country participates in an international convention or maintains diplomatic relations with Vietnam. In reality, exemptions are available only where specifically recognized under Vietnamese law, applicable international treaties, or reciprocal arrangements between the relevant jurisdictions. Furthermore, legalization procedures vary considerably from one country to another.
Where documentary deficiencies are identified, Vietnamese licensing authorities frequently issue formal requests requiring investors to provide additional legalized documents or to repeat authentication procedures before the Investment Registration Certificate ("IRC") may be granted. Such requests often extend the licensing timeline and increase administrative costs, particularly where documents must be reissued overseas and undergo the legalization process once again. From a practical perspective, these delays can be significantly reduced through careful advance planning. Investors are encouraged to identify legalization requirements at the earliest stage of project preparation, verify whether treaty exemptions are applicable, prepare updated corporate documents before commencing legalization, engage qualified translators familiar with legal terminology, and coordinate closely with legal advisers throughout the investment registration process.
