Vietnamese legal documents form a ladder: the Constitution at the top, then codes, laws and National Assembly resolutions, then documents of the Standing Committee and the President, then Government decrees, Prime Minister decisions, ministry circulars, and finally provincial and commune documents. A lower document must comply with every document above it. When two rules clash, the higher one generally prevails, and between documents from the same body, the later one generally does.
Knowing the ladder lets you judge how much weight a piece of paper carries. A circular can tell you which form to file; it cannot take away a right that a law grants. An official letter from a ministry answering one company's question is useful evidence of how officials think, but it is not law at all. This article explains each rung, how to read a document's status, and where foreigners most often go wrong.
Why the ladder matters in practice
Vietnam calls its binding rules legal normative documents. The category is defined by a dedicated law on the promulgation of legal documents, which was itself replaced by a new version in 2025 as part of the broader reform of how laws are drafted. That law lists which bodies may issue which types of document, and it is the reason a decision signed by a provincial department head, for example, carries far less weight than a decree signed by the Prime Minister on behalf of the Government.
The ladder matters most when something goes wrong. If an official demands a document that no regulation requires, or applies a local practice that contradicts a decree, the hierarchy is the tool you use to push back politely. It also matters when you negotiate: a counterparty who cites a guidance letter is on weaker ground than one who cites a decree. And it matters for planning, because many laws take effect only once their implementing decrees are issued, so the date a law is passed is rarely the date its detail becomes usable.
The rungs from top to bottom
The list below simplifies the official classification but captures the order foreigners need. Names in Vietnamese are given because you will see them on the documents themselves.
| Level | Document type | Issued by |
|---|---|---|
| 1 | Constitution (Hien phap) | National Assembly |
| 2 | Codes, laws (Bo luat, Luat) and resolutions (Nghi quyet) | National Assembly |
| 3 | Ordinances and resolutions | Standing Committee of the National Assembly |
| 4 | Orders and decisions | President of the State |
| 5 | Decrees (Nghi dinh) and resolutions | Government |
| 6 | Decisions (Quyet dinh) | Prime Minister |
| 7 | Resolutions and circulars on judicial matters | Judicial Council and Chief Justice of the Supreme People's Court; Procurator General |
| 8 | Circulars (Thong tu) | Ministers and heads of ministry-level agencies |
| 9 | Resolutions and decisions | Provincial People's Councils and People's Committees |
| 10 | Resolutions and decisions within delegated powers | Commune-level People's Councils and Committees |
Some categories, such as documents of the State Audit Office or joint documents between bodies, also exist, and the exact list was revised in 2025. If a document's status matters to your case, check its legal basis paragraph, which states the higher documents it relies on, and confirm the current classification with a licensed lawyer.
Codes, laws and resolutions of the National Assembly
A code is simply a law of broad, systematic scope: the Civil Code, the Labour Code, the Criminal Code and the procedure codes. Ordinary laws cover specific fields such as enterprises, investment, land, commerce or intellectual property. Both have the same rank. The National Assembly also adopts resolutions, some of which are normative and can set special mechanisms for a city or pilot a policy before it is written into a law. In recent years these pilot resolutions have become more common, so a rule that looks unusual compared with the general law may come from such a resolution.
Laws are usually long on principle and short on procedure. They often contain a final chapter listing the matters that the Government shall regulate in detail, along with the effective date and transitional provisions. That last part deserves careful reading. Transitional provisions decide whether a contract, licence or case already in progress continues under the old rules or must switch to the new ones, and they are a frequent source of disputes after a major amendment.
Decrees and circulars: where the detail lives
Decrees are the workhorses. A Government decree typically sets the conditions to qualify for something, the dossier to submit, the processing authority and, in a separate family of decrees, the administrative penalties for breaches. When an industry says a law is not yet in effect in practice, it usually means the decree is missing or under revision.
Penalty decrees deserve their own search. Administrative fines are not usually set out in the main law. They sit in sector penalty decrees, which are amended on their own timetable. Never assume a fine amount from an old article; check the current penalty decree or ask the authority.
Circulars carry the forms. A ministry circular provides templates, technical standards and guidance for officials. Because circulars are what front-line staff consult, they often decide in practice whether your file is accepted, even though they rank below decrees.
Watch for decrees that amend several others at once. The Government sometimes issues a single decree that changes provisions across many earlier decrees, for example to simplify procedures. These omnibus amendments are easy to miss if you only search by the title of the decree you know.
Circulars cannot add obligations the law does not allow. In principle, a circular may only guide matters assigned to the ministry. If a circular appears to create a new condition with no basis in a law or decree, that is a point to raise with the authority or a lawyer, not something to ignore on your own.
Local documents from provinces and communes
Provincial People's Councils adopt resolutions and People's Committees issue decisions on matters the central rules leave to local government. Examples include certain fees and charges within national frameworks, land price tables, local planning, and the internal organisation of public services. After the 2025 mergers, newly combined provinces had to harmonise documents that were previously issued by separate provinces, so for a period two sets of local rules may coexist for different parts of the same province. Ask which document applies to your address, not just to the province's name.
Commune-level authorities also issue documents within powers delegated to them, and since the district tier disappeared they handle more first-contact administration. Their documents rank lowest and must comply with everything above. If you run a business with sites in several provinces, expect some procedural differences and keep a short register of the local decisions that affect each site.
Local documents are also where the 2025 changes show most clearly in daily life. A decision may still name a district office that no longer exists, while the task it describes has moved to a commune or to a provincial department. When that happens, the substance of the rule usually survives the change of address; what you need to find out is which office now receives the file.
When two rules conflict
Higher rank prevails. A decree that conflicts with a law yields to the law; a provincial decision that conflicts with a circular yields to the circular. In practice, officials may still apply the lower document until it is formally amended, so you may need to request a written response or use a complaint procedure.
Later beats earlier from the same issuer. If the same body issues two documents on the same issue with different content, the later one generally applies. This is why checking for amending and replacing documents is essential.
Special rules can displace general ones. Vietnamese practice often treats a law dealing specifically with a subject as taking priority over a general law on the same point, though the drafting of each law may state its own priority rule. Read the scope clause at the start of each law.
Treaties have a special place. Where an international treaty to which Vietnam is a member provides differently, the treaty generally applies, except as against the Constitution. For a foreign investor, a bilateral treaty can change the answer to questions about expropriation or dispute resolution.
How to check whether a document still applies
Before you rely on any regulation, run through these steps. They take a few minutes and prevent the most common research error, which is quoting a text that has already been replaced.
- Find the Vietnamese title, number and issue date, and note the issuing body.
- Read the effective date and the transitional provisions near the end of the document.
- Search for later documents that amend, supplement or replace it, including consolidated versions, which combine an original text with its amendments.
- Check whether the document's legal basis, the higher law it implements, has itself been replaced; if so, the lower document may have lapsed in part.
- Look at the names of authorities in the text and map them to current bodies after the 2025 mergers.
- Where the result affects money, liability or a deadline, ask the competent authority in writing or have a licensed lawyer confirm the position.
Official letters, often called cong van, deserve a final word. Ministries and departments frequently answer questions from businesses with letters. These letters are not legal normative documents and bind no one else, but they reveal how an authority reads a rule. Keep them, cite them carefully, and do not present them as law.
When you need a Vietnamese lawyer
Legal research in Vietnam is a matter of finding the right combination of law, decree, circular and local decision, all in force on the relevant date. For a routine question, careful reading may be enough. When you are about to invest, terminate a contract, respond to an inspection, or argue that an official is applying the wrong rule, ask a licensed Vietnamese lawyer to confirm the full chain of documents and how the authority currently applies them.
A good lawyer will cite the specific provisions and the effective dates, tell you where the position is uncertain, and explain whether an official letter or local practice is likely to matter more than the formal hierarchy suggests. If an adviser answers only from memory without naming the current text, ask for the source. That request is normal in Vietnam and protects both of you.
It also helps to tell your lawyer which English sources you have already read. If a translation you relied on is outdated or misleading, a lawyer can point out the gap quickly, and you will understand why the advice differs from what you found online.
Frequently asked questions
What is the difference between a decree and a circular in Vietnam?
A decree is issued by the Government to implement a law and usually sets conditions, procedures and penalties. A circular is issued by a minister to guide implementation within the ministry's field, often with forms and technical detail. A decree ranks above a circular, and a circular must comply with the decree and the law.
Which document prevails if a decree conflicts with a law?
The law prevails because it ranks higher. In practice an official may continue applying the decree until it is amended, so you may need to raise the conflict in writing, through a complaint, or with the help of a lawyer rather than simply refusing to comply.
Is an official letter from a ministry legally binding?
An official letter answering a specific question is not a legal normative document and does not bind other parties or courts. It does show how the authority interprets a rule and can be useful evidence. Keep a copy and treat it as guidance rather than law.
How do I know if a Vietnamese regulation is still in force?
Check the effective date, then look for later documents that amend, supplement or replace it, and see whether the higher law it implements has been replaced. Consolidated versions help. For decisions with financial or legal consequences, ask the authority in writing or have a licensed lawyer confirm.
Can a province make its own rules in Vietnam?
Yes, within limits. Provincial People's Councils and Committees issue resolutions and decisions on matters the central rules leave to them, such as certain local fees and land price tables. These documents rank below central documents and must comply with them.
Why does a new law not seem to apply yet?
Many laws depend on implementing decrees and circulars for their detail. If those documents are delayed or still being revised, authorities may be unable to process applications under the new rules. Transitional provisions in the law explain how matters already in progress are handled.
