Registering securities or obtaining authorisation from the CMVM, Portugal's securities market regulator, typically involves submitting documentation that was originally drafted in English, French, or another foreign language. The practical question is straightforward: what translation requirements apply, and what quality standard must be met for documents to be accepted?
What the CMVM Requires in Terms of Language
The CMVM accepts documentation in Portuguese and, in certain situations provided for under the Prospectus Regulation (EU) 2017/1129 and supplementary legislation, in English. However, when a document is submitted in a foreign language before Portuguese authorities, or when national law requires a Portuguese version, a translation must be provided.
The most common situations requiring translation include:
- Admission prospectuses drawn up abroad and passported into Portugal
- Annual reports and accounts of foreign issuers with securities listed on Portuguese markets
- Fund regulations for investment funds constituted in other jurisdictions
- Contracts, articles of association, and constitutional acts of entities applying for authorisation or registration
- Disclosure of inside information where the CMVM requires publication in Portuguese
The general principle is that the translation must be faithful to the original, must not introduce ambiguities, and, where the document carries legal effect, must offer guarantees of authenticity equivalent to those of the source document.
Simple, Certified, or Sworn Translation: Which Applies?
Understanding the distinction between these three formats is essential to avoid procedural errors.
Simple translation is carried out by a qualified linguist without any formal declaration of conformity with the original. It is acceptable for internal supporting documents, working drafts, or situations where the CMVM only needs to understand the content without the document producing direct legal effects.
Certified translation is produced by a service provider that issues a declaration of conformity with the original. M21Global, for example, issues this type of declaration under its ISO 17100:2015 certification audited by Bureau Veritas. This is the most common standard required for regulatory documentation that does not require notarial involvement.
Sworn translation (tradução juramentada) is carried out by a translator recognised by an official body (in Portugal, the Ministry of Foreign Affairs) and has the status of a public document. It is required when source documents must produce full legal effects within the Portuguese legal order, or where there is an express legal provision to that effect.
For the CMVM context, certified translation is the appropriate format in most situations. Sworn translation is typically required for notarised documents, powers of attorney, and constitutional acts forming part of more complex authorisation processes.
Quality Requirements That Financial Documentation Demands
Documentation submitted to the CMVM is not equivalent to an internal manual or a commercial presentation. Errors carry consequences: delays in the registration process, requests for clarification, or, in more serious cases, rejection of the documentation.
Four quality dimensions must be assured:
Terminological accuracy. Terms such as *net asset value*, *underwriting*, *debenture*, *benchmark*, and *escrow* have established equivalents in Portuguese and in Portuguese law. Inconsistent or incorrect terminology creates interpretive problems and may be read as a lack of technical rigour.
Consistency with the source. The translation cannot omit clauses, alter figures, dates, or percentages, or soften language that is binding in the original. The CMVM may compare the translated version with the source document, and any discrepancy creates problems.
Alignment with the Portuguese regulatory framework. Some legal concepts have no direct equivalent. The translator must be able to distinguish between adapting and distorting, and should have training or experience in securities law.
Process traceability. For regulatory documentation, the translation should be accompanied by process documentation: who translated, who reviewed, and which glossaries and references were used. This is particularly relevant in the event of an audit or challenge.
For a closer look at how these requirements apply to prospectuses specifically, the article on translating prospectuses for international stock exchange listings covers the topic in detail.
How to Prepare Documentation Before Sending It for Translation
The translation process moves faster and requires fewer revision rounds when documentation arrives well prepared. These practices reduce turnaround time and the risk of inconsistencies:
- Always supply the original document in an editable format (Word, Excel, or text-selectable PDF), not scans
- State explicitly the language pair and regulatory destination (CMVM, central bank, foreign authority)
- Provide sector glossaries or previous translations from the same issuer, if available
- Identify concrete regulatory deadlines so the project manager can plan delivery accordingly
- Separate annexes that require translation from those provided for reference only
The more context shared before work begins, the lower the likelihood of terminological queries that delay delivery.
How M21Global Supports Issuers and Financial Intermediaries
M21Global provides financial translation services with teams specialised in regulatory documentation, prospectuses, annual reports and accounts, and capital markets contracts. The workflow for documentation destined for the CMVM follows the Strategic service tier: three linguists (translator, reviewer, and QA reviewer), audited under the ISO 17100:2015 certification, with a dedicated project manager and a three-hour response time.
For organisations evaluating translation providers for this type of work, the criterion is not linguistic competence alone. It is the ability to produce a document that withstands regulatory scrutiny, maintains terminological consistency across hundreds of pages, and arrives within the deadline set by the regulatory calendar. Contact M21Global to discuss the requirements of the project and receive a proposal tailored to the registration process underway.

Frequently Asked Questions
Does the CMVM accept documentation in English without translation?
In certain situations provided for under the EU Prospectus Regulation (2017/1129), the CMVM accepts documentation in English. However, where national law requires a Portuguese version or where documents must produce legal effects in the Portuguese legal order, a translation is required.
What is the difference between certified and sworn translation for CMVM purposes?
Certified translation is produced by a qualified provider that issues a declaration of conformity with the original, and is the standard required for most regulatory documentation. Sworn translation, carried out by an officially recognised translator, is required when documents must produce full legal effects, such as powers of attorney or constitutional acts.
Which financial documents most commonly require translation for the CMVM?
The most common are admission prospectuses passported from another country, annual reports and accounts of foreign issuers, regulations of investment funds constituted in other jurisdictions, and contracts or articles of association of entities applying for authorisation or registration.
How long does translation of a prospectus or annual report typically take?
Turnaround depends on document volume, language pair, and the level of review required. For complex regulatory documentation, timelines typically range from several days to two weeks. Sharing the specific regulatory deadline with the translation provider at the outset is essential to ensure on-time delivery.
Is ISO 17100 certification relevant for financial translation submitted to the CMVM?
Yes. ISO 17100:2015 certification ensures the translation process includes independent review and audited quality controls. For regulatory documentation subject to scrutiny by authorities such as the CMVM, this certification provides process traceability and accountability.
