VIAC Arbitration Rules: 8 Things Foreign Companies Should Check

The VIAC arbitration rules were updated in 2026, and the new version took effect on Jul 1st, 2026. If your Vietnam contracts name VIAC, the update will apply to your contract templates, how you file a claim, who you must disclose, and how fast a case can proceed. Not understanding the updated VIAC arbitration rules, and how they affect your case, can cost time, money, and control at the worst possible moment.

VIAC is the Vietnam International Arbitration Centre, the main body that runs commercial arbitration in Vietnam. Its rules decide how a dispute moves from the first filing to the final award. When those rules change, a foreign company that uses VIAC clauses needs to check a few practical things before the next contract is signed or the next dispute begins. The understanding of arbitration rules is just part of understanding the arbitration in Vietnam, and the points below focus on what affects your business directly.

The reality is that, most foreign managers treat the arbitration rules as background detail, something only the dispute lawyers read. But these rules decide practical outcomes: whether you can combine related claims, how quickly you must act, and whether an early mistake can weaken an award you later try to enforce.

VIAC Arbitration Rules: 8 Things Foreign Companies Should Check

What Changed in the VIAC Arbitration Rules

The new rules replaced the 2017 version and apply to cases that start on or after Jul 1st, 2026. Cases already running under the 2017 rules stay under those rules until they end.

For a foreign company, five practical areas became more detailed. Bringing claims across several contracts now has a clearer route. Adding a party or combining related cases has a defined procedure. A funded party must now disclose who is paying for the dispute. Email and VIAC’s online case platform are recognized for official notices. And a faster expedited track can apply in more situations, sometimes without a separate request. Each area impacts a business consequence, and the points below explain what each one means for you.

Check Which VIAC Rules Apply to Your Dispute

Start with timing, because the wrong rulebook means the wrong deadlines. The 2026 rules apply to cases that begin on or after Jul 1st, 2026. Cases already in progress continue under the 2017 rules.

This is a real problem for a company with older contracts. A contract signed years ago can still produce a fresh dispute today, and that new case would fall under the 2026 rules. So the signing date does not answer the question. What matters is when the arbitration begins, what the clause says, and whether the parties agreed anything different.

The consequence of getting this wrong is not small. Deadlines, the way arbitrators are appointed, and what you must disclose can differ between the two versions. A team that prepares under the old rules out of habit can miss a step the new rules now require, and lose ground before the case even starts.

It is safer to check again for every active or likely VIAC dispute recording the contract date, the clause wording, when the case started or may start, which rules apply, and any agreement that changes the default. 

Update Your VIAC Clause Templates

A clause that worked under the old rules may now leave gaps. When related contracts carry mismatched dispute clauses, you can lose the ability to bring the dispute together later, and end up running parallel cases at double the cost.

A supply deal, a project contract, a distribution network, a guarantee, and a shareholder arrangement often bind together. If each one names a different forum or different rules, combining them later becomes hard or impossible. The 2026 rules make the compatibility of those clauses a practical filing issue, not a theoretical concern. VIAC publishes a model clause, and a separate model clause for the expedited track, which is a sensible starting point. The mistakes in drafting arbitration clause in Vietnam could cause trouble.

Before your next contract goes out, review the whole set of related documents, not only the main one. Line up the forum, the rules, the language, the seat, and the party names across all of them, so a future dispute can be run as one case rather than several.

Plan Multi-Contract Claims Before You File

The first filing decision can cost you money. File too broadly without explaining how the contracts connect, and you may have to amend and refile. File as separate cases when one combined case was possible, and you pay more, wait longer, and risk two tribunals reaching different answers on the same facts.

The 2026 rules give a clear path when a dispute involves more than one contract. You either file a separate request for each arbitration agreement, or file one request that asks for the claims to be handled together and identifies how each claim links to each agreement. The President of the Centre then decides whether to allow the combined case, looking at whether the contracts are related or part of the same transaction or series of transactions, whether the questions of law or fact are similar, and whether the arbitration agreements are compatible.

The practical step here is to consider related contracts before filing. List each contract, each arbitration agreement, each party, each claim, and the factual link between them. 

Treat Joinder and Consolidation as Drafting Issues

Adding a party or combining cases is not only a step you take after a dispute starts. It should shape how you draft contracts now, because if the clauses are not compatible, you may be forced into parallel proceedings you cannot merge which could cost more time and money.

The 2026 rules give a defined institutional path for both, and this is a real change worth noting. Earlier Vietnamese arbitration practice did not offer a clear institutional route to pull an outside party into a case, so a company could not assume a related party would be joined. Under the new rules, cases may be consolidated where all parties agree, where the claims sit under the same arbitration agreement, or where compatible agreements connect to the same relationship, transaction, or series of related transactions. A party may be joined where everyone, including the additional party, agrees in writing, or where the additional party is on its face already bound by the arbitration agreement in play. This comes up often in construction projects, supply chains, guarantees and parent-company letters, joint ventures, and distributor networks, where the duties usually sit in separate documents.

Whether the Centre or the tribunal actually allows it still depends on the clauses, the parties, the facts, and the stage of the case. So the position is that this is a route to plan for, not a right you can count on. Where one relationship uses several documents, check early whether the dispute clauses are compatible enough to support consolidation or joinder. If they are not, expect the real possibility of parallel proceedings.

Add a Funding Check to Your Dispute Intake

The risk here is a disclosure failure that nobody inside the company saw coming. Outside funding is often known to finance or senior management, but not to the person who actually files the case. A missed disclosure then creates avoidable trouble at a wrong moment.

This is another area the 2026 rules changed. Vietnamese law has not specifically regulated third-party funding, and it remains permitted rather than banned. What is new is that the rules now bring funding into the open. A party whose dispute is paid for by an outside funder must disclose that the arrangement exists, in the Request for Arbitration, the Statement of Defense, or as soon as practicable after entering into it, and must give the funder’s name and contact details. The tribunal can order further disclosure about the arrangement if it decides that is needed.

The practical point is not only whether funding is used. It is who inside the company knows about it, records it, and discloses it in time. The fix is a single question on your dispute intake form, asking whether any funder, insurer, parent company, affiliate, or claims buyer is financing the case. If the answer is yes, counsel can then handle the disclosure the rules now require.

Control Email, the Online Platform, and Deadlines

A missed deadline is one of the worst ways to lose a case, and electronic notice makes it easier to miss. If an official notice lands in one employee’s inbox while they are on leave, the clock may already be running before anyone reads it.

The 2026 rules recognize email and VIAC eCase, the centre’s online case platform, as proper channels for notices and documents, and they set out how time limits are counted, including that the triggering day is not counted and the period runs from the next day. That puts the burden on your internal system. If notice can arrive by email or through the platform, someone must capture the receipt, record the date, calculate the deadline, and own the next step.

The safe setup is to stop letting arbitration notices sit in a single person’s inbox. Use a shared dispute mailbox, a controlled way to access the VIAC platform, a named person responsible for deadlines, and a rule for saving proof of delivery and upload. How these deadlines fit the wider timeline is part of the arbitration procedure in Vietnam that one needs to be aware of.

Check the Expedited Track Before It Applies to You

Speed is not always on your side. A faster track can help a claimant with a clean paper case, and hurt a party that needs time to gather evidence or call witnesses. Under the 2026 rules, the expedited track can apply in more situations, so this becomes a planning question at the clause stage, not only at filing.

For contracts signed after the new rules took effect, agreeing to use VIAC can be treated as agreeing to a possible expedited track, decided by the President of the Centre. A party can also request the expedited track before the tribunal is formed, where the amount in dispute is under the threshold VIAC publishes, the case suits a faster process, or the parties agree. In practice, the expedited track usually means a sole arbitrator, shorter timelines, hearings that may be held online, and an award within a set period. You can also expressly exclude the expedited track in writing if you do not want it.

So the decision to make now, at the drafting stage, is whether you want the expedited track, want to exclude it, or want it only for certain contracts. For a live case, weigh the amount at stake, the evidence you need, and whether speed helps or hurts your side.

Preserve the Record for Objections and Enforcement

If you notice a procedural problem and do not object in time, you can lose the right to raise it later, both before the tribunal and before a court. A complaint you never put in writing is a complaint you cannot use when the award is challenged or enforced.

Under the 2026 rules, a party who sees a breach of the arbitration law, the rules, or the arbitration agreement must raise the objection within the set time, or at the latest before the tribunal declares the final hearing, in writing and with supporting evidence. If you miss that window, the objection is treated as waived before both the tribunal and the court. Questions about arbitrator independence and how arbitrators are appointed matter most when a case has several parties, combined cases, or the expedited track.

For a company, this means objections cannot live as casual emails or comments in a meeting. They need to be reviewed, put in writing where required, supported by evidence, and saved. The better way to utilize this is a procedural record file kept from day one, holding notices, appointment records, arbitrator disclosures, conflict checks, objections, tribunal orders, hearing notices, proof of service, funding disclosures, and proof that deadlines were met. That file is what stands behind you if the award is later attacked, and when you reach the stage of enforcement of foreign arbitral awards in Vietnam. The strength of the underlying proof matters too, which is part of evidence in arbitration in Vietnam that one needs to keep.

Frequently Asked Questions About the VIAC Arbitration Rules

Q1: Do the current VIAC arbitration rules apply to every VIAC case now?

No. The 2026 rules apply to cases that started on or after Jul 1st, 2026. Cases already running under the 2017 rules continue under those older rules until they finish.

Q2: Should foreign companies replace all their VIAC clauses right away?

Not mechanically. First check whether related contracts use compatible clauses, and whether you want to address combined cases, added parties, funding disclosure, electronic notices, and the expedited track more clearly. VIAC’s model clause is a sound starting point.

Q3: Is third-party funding banned under the VIAC arbitration rules?

No. Funding is permitted, not banned. What the 2026 rules add is disclosure: a funded party must reveal that the funding exists and give the funder’s name and contact details, and the tribunal can ask for more detail.

Q4: Can a company rely on email for VIAC notices?

Yes. The 2026 rules recognize email and VIAC eCase for notices. The business risk is record control, so keep proof of what was sent, received, uploaded, and when the deadline falls.

Q5: Does the expedited track always make a case faster?

Not always. The track sets shorter timelines and often a sole arbitrator, but the amount in dispute, the parties’ positions, the evidence needed, and the Centre’s decisions all shape the real pace. 

Conclusion

The VIAC arbitration rules decide practical things that reach a foreign company’s money, timing, and control, not just the legal shape of a dispute. The 2026 update did not change the goal of arbitration, but it did sharpen how claims are combined, how parties are added, what must be disclosed, how notices travel, and how fast a case can run.

It is suggested to check the clause, the intake process, and the record before a dispute starts, not after.
