What to Do After Receiving an HKIAC Notice of Arbitration: Answer, Jurisdiction, and First Deadlines

An HKIAC Notice of Arbitration arrives in a shared company mailbox. The attachments seek repayment, damages, and arbitration costs far above management’s expectation. Procurement says the claimant still owes a final balance, while finance fears a bank-account freeze. Because the Notice arrived before a holiday, someone suggests waiting until next week.

Do not wait.

The immediate task is not a long merits defence. It is to preserve first-round procedural rights. In the first 72 hours, fix the receipt date, preserve originals, notify decision-makers and insurers, issue a legal hold, and collect the contracts. Within 30 days, address the Answer, jurisdiction, tribunal, counterclaims, cost, and Mainland preservation risk.

I act for respondents in HKIAC cases. This article explains the first decisions; it does not recommend procedural obstruction or concealment or transfer of assets.

First 24 hours: preserve proof of receipt before debating the merits

For email delivery, retain the original message file, full headers, attachments, sender, and server time. For courier delivery, keep the envelope, waybill, recipient, date, and tracking. Do not save the PDF and delete the original email.

Check for an HKIAC case number, claimant and representative, arbitration agreement, amount, and service method. A copy from claimant’s counsel should not be ignored merely because it did not come directly from HKIAC; the Rules require simultaneous service on HKIAC and the respondent.

An initial external response can be limited: acknowledge receipt, reserve rights, and state that the company is preparing its response. Before reviewing the contract and evidence, do not admit debt, promise payment, waive objections, or take a casual position on tribunal size.

A reservation of rights is not a substitute for action. Send the documents immediately to the people authorised to handle the arbitration.

First 72 hours: calculate the 30-day deadline and work backwards

Article 5 of the 2024 HKIAC RulesHKIAC | Hong Kong International Arbitration Centre2024 Administered Arbitration Rules - HKIAC | Hong Kong International Arbitration Centrehttps://hkiac.org/wp-content/uploads/2025/11/HKIAC_2024_Rules_05.mp4 The 2024 HKIAC Administered Arbitration Rules may be viewed in PDF format through the link…hkiac.org↗ generally requires the respondent to submit the Answer to HKIAC and the claimant within 30 days after receiving the Notice.

The period does not automatically start on the arbitration commencement date. Generally:

• count from the day after the respondent receives the Notice;
• include intervening holidays;
• roll forward if the last day is an official holiday or non-business day at the place of receipt;
• use local time at the place of receipt; and
• for multiple intended recipients, check the date of the last recipient under the Rules.

List every receipt time if the company has a Hong Kong office, Mainland factory, and different representatives. Ask HKIAC promptly if the calculation is uncertain rather than choosing the most favourable date yourself.

HKIAC may adjust a time limit set by the Rules or HKIAC for good cause, including in some cases after expiry, but an extension is not automatic. Apply before the original deadline with specific reasons while completing the work that can proceed.

The internal schedule should include contract and party review, interviews, legal hold, jurisdiction analysis, counterclaims, arbitrator candidates, drafting, management approval, and service.

Start document preservation, insurance notice, and communication control together

Issue a legal hold to relevant custodians and suspend deletion or overwriting of email, WeChat, WhatsApp, WeCom, ERP, quality, shipping, and payment records. Preserve original accounts, context, attachments, and devices, not only favourable screenshots.

Notify directors and legal, finance, sales, production, quality, and logistics leads, but control external communications. Use one collection team so employees do not contact the claimant separately or alter existing records.

Check insurance immediately. Product liability, professional liability, D&O, or other policies may contain notice deadlines. Coverage depends on the wording, but an internal coverage review should not cause a missed notice obligation.

The Answer is not the complete Statement of Defence

Under Article 5, the Answer generally includes:

• contact details for the respondent and representatives;
• any jurisdiction objection;
• comments on the nature and amount of the dispute;
• a response to the relief sought;
• a reasoned proposal for one or three arbitrators;
• a proposed sole arbitrator or respondent’s designation for a three-member tribunal;
• third-party funding disclosure; and
• confirmation and method of simultaneous service on the claimant.

The Answer may contain the Statement of Defence, but every case need not complete the full merits defence within 30 days. If the claimant filed a Statement of Claim with the Notice, decide whether to file the Defence at once based on the evidence, efficiency, and strategy.

Do not write only “all allegations denied.” Classify facts as admitted, not admitted, denied, or presently unknown, and respond separately to principal, damages, interest, costs, and conduct relief. This preserves positions without locking the company into inaccurate facts before interviews and collection are complete.

Break jurisdiction objections into four questions

Party. Is the named respondent a signatory or otherwise bound? The contract company, recipient of funds, factory, and group parent may differ.

Clause. Is there a valid arbitration agreement? Does it provide for HKIAC administration or only cite the Rules? Do several contracts contain conflicting clauses?

Scope. Do the refund, quality, warranty, tort, or affiliate claims fall within the wording? Raise an out-of-scope objection promptly after the issue appears.

Preconditions. Does the contract require negotiation, notice, or a cooling-off period? Whether a failure affects jurisdiction or admissibility depends on the clause and governing law; one missed meeting does not automatically invalidate the arbitration.

Article 19 adopts competence-competence and separability . Alleged invalidity of the main contract does not automatically invalidate the clause. Before the tribunal is formed, HKIAC generally performs a prima facie review and lets the tribunal decide the issue.

Where possible, raise jurisdiction in the Answer and generally no later than the Statement of Defence. Participation in arbitrator designation does not waive the objection, but it is not a reason to delay. Preserve the merits defence rather than relying entirely on a weak procedural point.

Tribunal size and candidates are influence easily lost in the first 30 days

Check whether the contract states one or three arbitrators. If not agreed within 30 days after receipt, HKIAC determines the number .

Consider complexity across contracts or parties, legal and technical expertise, procedural language, independence and conflicts, availability, added cost and scheduling of three arbitrators, and urgent preservation or threshold issues.

An arbitrator is not a party representative. Do not contact candidates privately about the merits. Use the formal nomination and disclosure process and raise independence or impartiality concerns promptly.

Identify counterclaims, set-off, and cross-claims at the Answer stage

The 2024 Rules ask the respondent, so far as possible, to state counterclaims, set-off defences, or cross-claims in the Answer, including the relevant contract, general nature, amount, and relief.

Supplier-side claims may include an unpaid balance, customised-goods loss after cancellation, storage, specification changes, or wrongful rejection. “The buyer owes us too” is not a complete counterclaim. Check contractual basis, governing law, calculation, evidence, and whether the claim is against a party to the arbitration agreement.

Set-off is not established by attaching another invoice. Its availability and timing depend on substantive law and scope. If affiliates are involved, assess joinder or cross-claims under the Rules instead of waiting until after the Defence.

Deposits and procedural choices require a real budget

HKIAC generally requests equal deposits. Counterclaims and cross-claims may increase or separate deposits. If one party does not pay, another may substitute payment; relevant claims may otherwise be suspended or terminated. Reimbursement can later be sought from the tribunal.

Budget for arbitrators, counsel, translation, technical or quantum experts, witness preparation, hearings, document platforms, and preservation response, not just the registration fee. The HKIAC fee calculator provides an initial range.

For a claim that is manifestly without legal merit, manifestly outside jurisdiction, or incapable of producing a favourable award even on the alleged facts, consider early determination under Article 43 . It is for clear, separable issues, not every factual dispute compressed into a short letter.

Security for costs may also be considered where appropriate, but it is discretionary and not automatic merely because the claimant is foreign or less well funded.

Assess Mainland preservation risk without moving assets

If the seat is Hong Kong and HKIAC administers the case, the claimant may seek property, evidence, or conduct preservation from a Mainland court under the interim-measures arrangementwww.doj.gov.hkwww.doj.gov.hk↗.

Finance and operations should lawfully identify payroll, tax, and operating accounts; mortgaged, leased, or third-party property; the operational effect of freezing inventory and equipment; substitute security; whether the amount is excessive; and whether the debtor entity is correct.

This information supports lawful objection, review, security, or operational planning. It is not a basis to hide or transfer property. Transfers, sham transactions, or deletion after the Notice can worsen preservation, arbitration, enforcement, and management risk.

If Mainland court papers have arrived, follow the order and local procedure immediately. An HKIAC jurisdiction objection does not permit ignoring a Mainland court order.

No Answer is not an automatic loss, but the case can continue

Article 26 does not create a simple default win. If a respondent without sufficient cause fails to defend, the arbitration may continue ; after proper notice, the tribunal may decide on the available evidence.

The claimant still bears its burden, but an absent respondent loses influence over the tribunal, jurisdiction, schedule, documents, witnesses, loss calculation, counterclaims, and relief. Later saying “we did not participate” is not a substitute for proof of improper notice or inability to present the case.

Even when settlement is preferred, protect the Answer deadline and necessary objections. Negotiation and procedural response can proceed in parallel.

The first-round strategy should produce five tables

Within 30 days, management should have a deadline table, jurisdiction table, merits-and-evidence table, counterclaim table, and preservation-risk table. Together they show whether to defend fully, seek early determination, adjust the procedure, or settle before cost expands.

Settlement should address payment, delivery, release of preservation, costs, confidentiality, and default consequences. A consent award or termination may be suitable depending on enforcement needs and wording.

Conclusion

After receiving an HKIAC Notice, the priority is not an immediate full Defence. Fix the receipt date, protect the 30-day Answer deadline, and address document preservation, jurisdiction, arbitrators, counterclaims, budget, and Mainland preservation together. The Answer is not the full Defence, but omissions can narrow later procedural choices.

Silence does not create an automatic loss, yet the arbitration can continue and the respondent can lose the chance to shape the case. Settlement discussions should run alongside necessary procedural steps, not replace them or prompt asset transfers.

If your company has received an HKIAC Notice, prepare the complete Notice and actual receipt time, clause, amount, core contracts and payments, possible counterclaims, and any Mainland court papers, then contact me. I accept respondent-side mandates. Use the ordinary form for a short case summary only; do not transmit unredacted sensitive attachments.
