A handful of Vietnamese legal terms come up again and again for foreigners: the names of document types such as luat, nghi dinh and thong tu; court words such as ban an, quyet dinh, nguyen don and bi don; and business concepts such as nguoi dai dien theo phap luat, the company's legal representative. Knowing what each really means, and where English translations mislead, helps you read papers, ask better questions and spot problems early.
This glossary groups the most useful terms by topic, gives a plain-English explanation and flags common misunderstandings. Terms are written without Vietnamese diacritics for easy reading; on official papers they carry full diacritics. The explanations are general and simplified. When a term decides a real question, confirm its meaning in context with a licensed Vietnamese lawyer.
Names of legal documents
These terms appear in the title of every regulation. Recognising them tells you at a glance how much weight a document carries.
| Vietnamese term | Usual English rendering | What it really is |
|---|---|---|
| Hien phap | Constitution | Supreme law, adopted by the National Assembly |
| Bo luat / Luat | Code / Law | Statutes passed by the National Assembly; a code is a broad, systematic law |
| Nghi quyet | Resolution | Issued by many bodies; weight depends entirely on the issuer |
| Nghi dinh | Decree | Government document implementing laws; source of most procedures and penalties |
| Quyet dinh | Decision | Issued by the Prime Minister, local committees and many agencies; may be normative or a one-off decision |
| Thong tu | Circular | Ministry document guiding implementation, often with forms |
| Cong van | Official letter | Correspondence, often guidance; not a legal normative document |
| Van ban hop nhat | Consolidated text | Original plus amendments combined for reading convenience |
The same word quyet dinh can describe a regulation issued by the Prime Minister or an individual decision granting you a licence or imposing a fine. Always check the issuer and whether the document addresses everyone or only you.
Courts, parties and procedure
Court papers use a precise vocabulary. Mistaking one term for another can lead you to miss a deadline or misjudge how final a ruling is.
| Vietnamese term | Usual English rendering | What it really is |
|---|---|---|
| Toa an nhan dan | People's Court | The ordinary courts; now supreme, provincial and regional levels |
| Vien kiem sat nhan dan | People's Procuracy | Prosecution and supervision of judicial activities |
| Ban an | Judgment | Ruling on the merits after a trial |
| Quyet dinh cua toa an | Court decision | Procedural or other rulings, such as recognising a settlement or suspending a case |
| So tham / Phuc tham | First instance / Appeal | The two ordinary levels of trial |
| Giam doc tham / Tai tham | Cassation / Reopening | Exceptional reviews of final judgments |
| Nguyen don / Bi don | Plaintiff / Defendant | The parties to a civil case |
| Nguoi co quyen loi, nghia vu lien quan | Person with related rights and obligations | A third party whose interests the case may affect |
| Hoa giai | Mediation or conciliation | Attempts to reach agreement, in or out of court |
| Thi hanh an dan su | Civil judgment enforcement | The separate system that enforces civil judgments |
A settlement reached in court is usually recorded in a court decision recognising the agreement, which can be enforced like a judgment. That is a quyet dinh, not a ban an, but its practical effect can be just as strong.
Watch also for the words that signal time limits, such as the period for appeal or for submitting evidence. They usually appear near the end of a court paper and run from receipt or from a stated date.
Company and business terms
Nguoi dai dien theo phap luat (legal representative). The individual registered with the business registration authority as representing the company in transactions and before authorities. The role carries personal responsibilities, and some obligations require the legal representative's presence or signature. It is not the same as any employee holding a power of attorney.
Giay chung nhan dang ky doanh nghiep (enterprise registration certificate). The document showing the company's registration number, name, address, charter capital and legal representative. The registration number is the company's key identifier and survives address changes.
Von dieu le (charter capital). The capital members or shareholders commit to contribute. Contribution deadlines and consequences of late contribution are set by law, and capital figures appear in many filings.
Con dau (company seal). Companies may use a seal, and in practice many documents are expected to carry it, although the legal requirements around seals have been relaxed compared with the past. Expect counterparties and officials to look for it.
Uy quyen / Giay uy quyen (authorisation / power of attorney). Authorising someone to act on your behalf. Formal requirements, such as notarisation or legalisation when signed abroad, depend on the purpose and on the receiving authority.
Hop dong (contract). Agreements are governed mainly by the Civil Code, with commercial and sector rules on top. Some contracts must be in writing, notarised or registered to be valid or enforceable.
Paperwork and certification terms
Cong chung (notarisation). A notary certifies the legality of a contract or transaction and, in some cases, the authenticity of signatures. Certain transactions, especially many involving land and houses, require notarisation.
Chung thuc (certification). Certification of copies against originals, of signatures or of some contracts, carried out by commune-level authorities, notary offices and certain other bodies. It confirms authenticity rather than the legality of content.
Ban sao (copy) and ban sao chung thuc (certified copy). Many procedures accept certified copies instead of originals. A plain photocopy usually will not do unless the procedure allows it or the original is shown for comparison.
Hop phap hoa lanh su (consular legalisation). The process by which a document issued abroad is authenticated for use in Vietnam, or a Vietnamese document for use abroad. Requirements depend on the countries involved and the applicable treaties.
Ban dich (translation). Foreign-language documents usually need a Vietnamese translation, often with the translator's signature certified, before authorities will accept them.
Thua phat lai and vi bang (bailiff and bailiff's record). Bailiffs are licensed professionals who can serve documents, verify and record events in a vi bang, and carry out certain enforcement tasks. A vi bang records facts the bailiff observed and can be used as evidence; it does not certify the legality of a transaction.
Ma so doanh nghiep (enterprise code). The single number that identifies a company in business registration and tax records. Quote it in contracts and correspondence, because names and addresses can change while the code stays the same.
False friends and other translation traps
These terms look simple in English but carry a different weight in Vietnamese practice.
- License. English translations use it for many different Vietnamese papers, from registrations to sector permits to approvals. Always ask for the Vietnamese name of the document.
- Dispatch. Older translations sometimes render cong van as official dispatch, which makes routine correspondence sound like a formal order.
- Red book and pink book. Informal names for land use and house ownership certificates, after the colour of their covers. The formal names are longer and changed over time.
- Fine versus penalty. Administrative penalties include fines but also warnings and additional measures, such as confiscation or suspension of a licence; contract penalties are a separate civil concept.
- Compensation. In contracts, damages for breach and an agreed penalty are distinct; in land matters, compensation refers to payment when land is recovered by the state.
- Lawyer. The title luat su is reserved for licensed members of a bar; a legal consultant or in-house adviser is not a luat su.
When you meet a term you cannot place, write down the Vietnamese words exactly as they appear and ask. A precise question about a specific term is far easier for an adviser to answer than a general question about a translated document. A photo of the heading and the paragraph where the word appears is often enough for an adviser to identify what kind of paper it is.
Building your own working vocabulary
You do not need fluent Vietnamese to work effectively with the legal system, but a small working vocabulary makes a large difference. Start with the twenty or thirty terms that appear in your own documents: the names of your licences, the key roles in your company, the type of contract you sign most often, and the court and procedure terms you might meet in a dispute. Keep a two-column list, Vietnamese and English, and update it whenever an adviser explains a new word.
Share the list with colleagues and advisers so that everyone uses the same English rendering for each Vietnamese term. Inconsistent translation inside a company is a frequent cause of misunderstanding, especially when documents pass between local staff, regional headquarters and foreign counsel. It also helps when you review contracts: a consistent glossary makes it easier to see whether the English and Vietnamese versions say the same thing.
Finally, learn to recognise the visual layout of key documents, such as the heading of a court summons or an enforcement decision. Knowing at a glance what kind of paper you hold lets you react quickly and pass it to the right person.
Be wary of learning legal vocabulary from informal forums or social media groups. Expat communities share useful experience, but terms are often used loosely there, and a word that describes one person's situation accurately may mislead you about yours.
When you need a Vietnamese lawyer
A glossary helps you understand; it does not tell you what a term means in a specific document or what you should do about it. Speak to a licensed Vietnamese lawyer whenever a paper from a court, procuracy, enforcement agency or inspectorate arrives, whenever a contract term carries significant money or risk, or whenever you and a counterparty read the same Vietnamese word differently.
Ask the lawyer to explain the key terms in your documents and how they apply to your situation, and add the explanations to your glossary. Over time, this builds internal knowledge that reduces the cost and stress of later matters. Before acting on any general explanation, including the simplified ones above, check the current rules with the competent authority or a licensed lawyer.
If you prefer to start with a quick orientation, you can ask a lawyer on AI Co Van what a particular term on your paper means and which follow-up questions to raise. Bring the original Vietnamese wording, not only a translation, so the explanation is tied to the exact words in front of you.
Frequently asked questions
What does nguoi dai dien theo phap luat mean?
It means the legal representative of a company: the individual registered with the business registration authority as representing the company in transactions and before authorities. The role carries personal responsibilities and is different from an employee who simply holds a power of attorney.
What is the difference between nghi dinh and thong tu?
A nghi dinh is a decree issued by the Government to implement laws, usually setting conditions, procedures and penalties. A thong tu is a circular issued by a minister to guide implementation, often with forms. A decree ranks above a circular.
What is the difference between ban an and quyet dinh in a court?
A ban an is a judgment deciding the merits of a case after trial. A quyet dinh is a court decision on procedural or other matters, such as recognising a settlement, suspending a case or returning a petition. Both can have important effects and deadlines.
What is the difference between cong chung and chung thuc?
Cong chung is notarisation, in which a notary certifies the legality of a contract or transaction. Chung thuc is certification, which confirms that a copy matches an original or that a signature is authentic, without certifying the legality of the content.
Is a cong van legally binding?
A cong van is an official letter. It is not a legal normative document and does not bind other parties or courts, although it can show how an authority interprets a rule. Keep such letters, but treat them as guidance rather than law.
Can anyone call themselves a lawyer in Vietnam?
No. The title luat su is reserved for people who hold a Vietnamese practising certificate and belong to a bar. Legal consultants and in-house advisers may give advice in some settings but are not luat su and cannot represent you as lawyers in court.
