The notice type and institutional framework determine your response obligations and timeline.
A party invokes arbitration under a contractual clause by serving a written notice. Arbitration proceedings commence from the date the other party receives the notice. Your 30-day window to nominate your arbitrator begins here.
Filed under rules of DIAC (Delhi), MCIA (Mumbai), ICC, or SIAC. The institution handles appointment if parties fail to agree. Response must be filed with the institution per their rules — typically within 15–30 days of the notice of arbitration.
Foreign seat arbitration (Singapore, London, Dubai) with enforcement in India under Part II of the A&C Act (New York Convention). Respond under the arbitration rules specified in the clause. Enforcement of foreign awards in India is through the High Court.
For disputes involving MSME suppliers, the MSME Facilitation Council refers disputes to arbitration under MSMED Act S.18 after conciliation fails. The buyer cannot challenge the jurisdiction — it is a statutory mandatory arbitration. Response time is per Council's directions.
When parties cannot agree on the arbitrator within 30 days, either party can approach the High Court under S.11 for appointment. If you receive a S.11 petition, you must respond to the High Court — this is a court proceeding, not an arbitration response.
Fast track arbitration under S.29B — sole arbitrator, documents only, award within 6 months. Emergency arbitration under institutional rules (24–48 hour interim relief). If invoked, respond immediately — timelines are compressed.
Your response to an arbitration notice sets the tone for the entire proceeding. These six moves cover both substantive and tactical positions.
Before engaging on merits, examine if the dispute is arbitrable. Non-arbitrable: consumer disputes (CPA 2019 gives consumer the choice), labour/employment disputes under IDA, insolvency proceedings, criminal matters, fraud where third parties are involved. If non-arbitrable, approach the High Court to restrain arbitration. Under the Kompetenz-Kompetenz principle, you must first raise this before the tribunal under S.16.
The arbitration clause must be: in writing (S.7), clear about the seat/venue/institution, not obtained by fraud or coercion. Vague clauses ("disputes to be settled by arbitration in Delhi") may be enforceable but invite disputes on seat. An arbitration clause in a void contract does not save arbitration — but the separability doctrine means a valid arbitration clause survives a voidable agreement.
For a 3-member tribunal: you must nominate your arbitrator within 30 days (S.11). Choose someone with subject matter expertise (construction, finance, technology). Ensure your nominee is independent and impartial — challenge opponent's nominee if they have any relationship to the claimant (S.12 conflict check using Fifth and Seventh Schedules). For a sole arbitrator: both parties must agree within 30 days or either can approach the High Court.
Under S.43, the Limitation Act 1963 applies to arbitrations. If the claimant's cause of action arose more than 3 years before the S.21 notice was served, the claim is time-barred. Raise this as a preliminary issue before the tribunal (S.16). The tribunal must decide this before proceeding to merits. A time-barred arbitration claim can also be challenged at the award enforcement stage.
If the claimant is likely to dissipate assets or if you need protective orders, approach the competent court under S.9 for interim measures: injunction restraining asset transfer, appointment of receiver, security for the claim, preservation of subject matter. S.9 relief can be sought even before the arbitral tribunal is constituted. After tribunal constitution, S.9 powers are curtailed — apply early.
File a counter-claim with the arbitral tribunal asserting your own claims against the claimant — breach of contract by the claimant, damages owed to you, setoff amounts. A counter-claim is resolved in the same arbitral proceeding, saving time and cost. The counter-claim must arise from the same contract or closely related transactions covered by the arbitration clause.
The 30-day window under Section 21 is your most important deadline. Missing it gives the claimant the right to approach the High Court under S.11 for sole arbitrator appointment.
Locate the specific clause in your contract that is being invoked. Review: (a) is the dispute within the clause's scope? (b) what is the agreed seat of arbitration? (c) what rules apply (ad hoc / DIAC / ICC)? (d) how many arbitrators? (e) is there a pre-arbitration dispute resolution step (mediation / negotiation) that hasn't been completed? A pre-arbitration step requirement can be used to stay the arbitration temporarily.
Key strategic decision: (a) If the dispute is non-arbitrable or the clause is invalid → approach High Court under S.8/S.11 to challenge before responding to the arbitrator; (b) If you have a limitation defense → decide if you want to raise it as a preliminary issue before the tribunal (faster) or let the arbitration proceed and challenge the award under S.34; (c) If jurisdiction is not disputed → focus on nominating your arbitrator and preparing counter-claims.
Send a formal written reply within 30 days of receiving the notice: (a) acknowledge receipt of the S.21 notice; (b) if proceeding: nominate your arbitrator with their consent and disclosure of relationships; (c) if challenging: clearly state you dispute jurisdiction and will approach the court; (d) reserve all rights and defenses. Send via Registered Post + Email to create a timestamped record.
Once the tribunal is constituted (all 3 or 1 arbitrator appointed), file your Statement of Defense per the timeline the tribunal sets (typically 30–60 days). Include: (a) specific denial of each claim item; (b) limitation plea; (c) jurisdiction objections (S.16); (d) counter-claim with full details and quantum; (e) documents relied on. The Statement of Defense is your primary pleading — it determines the scope of your defense in the final award.
If the arbitral award goes against you, challenge it in the High Court under S.34 within 3 months of receiving the award. Grounds are limited: patent illegality, public policy, arbitrator acted beyond scope, fraud, breach of natural justice. S.34 is NOT a re-hearing — courts do not re-examine facts. The limitation is strict: 3 months + 30 days maximum extension. S.34 also automatically stays award enforcement.
