This page is being published eight days before the rule it describes changes. That is deliberate, because the change is large, it is dated, and a file opened this week will straddle it.
The 1961 Hague Apostille Convention enters into force for Viet Nam on 11 September 2026. Viet Nam acceded on 31 December 2025; the entry-into-force date is fixed and appears in the HCCH status table, which as at 30 June 2026 records 130 Contracting Parties. Montenegro is a party by succession, in force 3 June 2006.
Viet Nam does not appear separately in the published nationality breakdown of Montenegro's 40,567 foreign workers from 107 countries in 2025.
Legal position stated as at 3 September 2026.
What changes, and what it means for a file already open
Until 11 September 2026, a Vietnamese public document destined for a Montenegrin administrative file requires the full consular legalisation chain: authentication by the competent Vietnamese authorities, then legalisation by the mission competent for Montenegro.
From that date, between Viet Nam and Montenegro, an apostille is sufficient. The consular leg disappears.
The practical questions this raises are ordinary but easy to get wrong:
- A document already legalised under the old chain does not become invalid. Legalisation performed while the old regime applied remains what it is.
- A document not yet started should almost always wait, unless the delay is genuinely material. Starting a consular chain in the first week of September to save a few days is a poor trade.
- Certified translation into Montenegrin remains a separate step in both regimes. The apostille removes the consular leg, not the translator.
⚠️ Do not treat the date as a soft transition. Guidance, agency practice and even consular pages will lag it. If you are told in October that a Vietnamese document still needs consular legalisation for Montenegro, check the status table rather than accepting it.
The sending-side framework: Law 69/2020/QH14
Outbound employment from Viet Nam is governed by the Law on Vietnamese Guest Workers, No. 69/2020/QH14, issued on 13 November 2020 and in force from 1 January 2022, replacing Law No. 72/2006/QH11.
Two features matter to a foreign employer.
The contract structure is prescribed. A contract for sending Vietnamese workers abroad must contain clear agreement on the rights and obligations of each party, must be consistent with the labour supply contract, and must set out the service charge and other expenses explicitly. The chain of documents has to align; a service arrangement that contradicts the labour supply contract is not merely untidy, it is non-compliant.
Workers hold statutory termination rights that survive your contract. A Vietnamese guest worker may unilaterally terminate in cases of ill-treatment, forced labour, an explicit risk directly threatening life or health, or sexual harassment. These are not terms you negotiate; they sit above the contract.
The social insurance point, and why Montenegro is on the wrong side of it
Law 69/2020 exempts Vietnamese guest workers from double social insurance contributions and double personal income tax where the destination country has signed an agreement on social insurance, or an agreement for the avoidance of double taxation, with Viet Nam.
Montenegro has no social security agreement with Viet Nam. So the exemption does not engage on the social insurance side, and contributions are paid where the work is performed with no aggregation of insurance periods between the two systems.
This is a real cost and a real conversation to have with the worker before he signs — not because it stops anything, but because a Vietnamese worker who has been told by an agency that he is exempt has been told something that is true of other destinations and not of this one.
The Montenegrin half, briefly
The receiving side is ordinary. In short: Article 66(1) of the Zakon o strancima allows work only on a residence-and-work permit or a work registration certificate — an entry route is never a work route — and only the permit bases under Article 40(3) consume the annual quota, set at 28,988 for 2026.
The filing mechanics, the quota, the eight no-permit situations under Article 67(1) and the Article 85 certificate list are in our guide to foreign worker employment in Montenegro and the quota page.
Sequencing, for a file opened this month
- Hold the document chain until 11 September unless waiting genuinely costs you the engagement.
- Align the contract documents so the sending contract and the labour supply contract say the same thing about charges and obligations.
- Settle the social insurance position in writing with the worker, given that the Law 69/2020 exemption does not apply to this destination.
- Apostille and translate from 11 September.
- The Montenegrin permit, then the contract-and-insurance registration within 24 hours of issuance, counted from the permit date rather than the arrival date.
What this page does not tell you
It does not advise on Vietnamese law — for the licensing of the sending enterprise, the permitted service charges and the form of the contracts, take Vietnamese advice. It does not tell you what a Vietnamese authority will accept in the transition week; where a document is time-critical, ask before you assume.
RoNa Legal is a registered employment intermediary under activity code 78.10 and a legal adviser. We do not supply, lease or second workers, and we are not an employer of record. We build the Montenegrin file and coordinate with licensed agencies where the structure requires one.
Send us the engagement structure before you start the document chain — this month, the sequencing decision is worth more than anything else on this page. Our services are set out on the services page and a file can be opened through the contact page.
