How to Send an Arbitration Notice in India: Section 21 and Invoking Arbitration

When a contract with an arbitration clause breaks down, the first formal step is usually to send an arbitration notice. Knowing how to send an arbitration notice in India under Section 21 of the Arbitration and Conciliation Act 1996 matters because, in most cases, arbitration proceedings legally commence only when the other side receives this notice. A defective or missing notice can delay or even derail the entire dispute.

Why the Section 21 Notice Matters

Section 21 of the Arbitration and Conciliation Act provides that, unless the parties agree otherwise, arbitral proceedings in respect of a dispute commence on the date the respondent receives a request to refer that dispute to arbitration. This notice is therefore the formal trigger for arbitration. Courts have treated it as a mandatory precondition, so that without a valid Section 21 notice, an application to a court for the appointment of an arbitrator may not be maintainable.

In short, the notice is not a mere formality. It fixes the date of commencement, which can be important for limitation, and it sets the process in motion.

What the Notice Must Contain

A clear arbitration notice should identify the parties and the contract, refer specifically to the arbitration clause being invoked, and describe the dispute and the claims being raised. Most importantly, it must express an unambiguous intention to refer the dispute to arbitration and call upon the other party to agree to the reference. Where the clause requires the parties to jointly appoint an arbitrator, the notice should propose a name or invite the other side to do so.

The notice should be sent to the correct address of the other party, with proof of delivery retained. A vague communication that merely complains about a breach, without clearly invoking arbitration, may not satisfy Section 21.

What Happens After You Send It

Once the notice is received, the other party has the opportunity to respond and, where required, to agree on the appointment of an arbitrator. If the parties cannot agree, or the other side fails to act, a party may approach the High Court or the Supreme Court under Section 11 for the appointment of an arbitrator. The limitation for filing a Section 11 application typically begins after the failure to make an appointment within thirty days of the notice invoking arbitration.

It is also worth checking whether the dispute is actually arbitrable, because some matters are reserved for special forums. For example, the Kerala High Court held that certain corporate restructuring and asset division disputes are non arbitrable and belong to the NCLT.

Practical Tips and Pitfalls

Keep proof of service of the notice, mind the limitation period for your underlying claim, and ensure the notice is signed by an authorised person. Confidentiality is a feature of arbitration, but it is not absolute, as shown when the Bombay High Court held that court disclosure orders can override arbitration confidentiality clauses. Where a contract requires a notice before action, delay in sending it is not always fatal, as the Supreme Court clarified that delay in a legal notice is not a ground to deny specific performance.

Drafting the notice with care at the outset reduces the risk of preliminary objections and helps the arbitration begin on a firm footing.

Number of Arbitrators and the Seat of Arbitration

When invoking arbitration, it helps to keep two practical questions in mind: how many arbitrators will decide the dispute, and where the arbitration is seated. The arbitration clause itself usually answers the first question. The law requires that the number of arbitrators must not be an even number, so parties commonly agree on a sole arbitrator or a panel of three. If the clause is silent, the default position is a sole arbitrator.

The seat of arbitration is equally important, because it determines which courts will supervise the arbitration and exercise powers such as appointing an arbitrator or granting interim relief. A notice that respects the clause on these points reduces the scope for preliminary disputes. Where urgent protection is needed before the tribunal is constituted, a party can also seek interim measures from a court, which is a separate but related step in the same process.

Why a Well Drafted Arbitration Clause Helps

Much of the difficulty in invoking arbitration can be avoided at the contract stage by drafting a clear arbitration clause. A good clause specifies the number of arbitrators, the method of appointment, the seat and venue of arbitration, the governing law and the language of the proceedings. When these matters are settled in advance, the notice invoking arbitration becomes straightforward and there is less room for the other side to raise preliminary objections.

A vague or incomplete clause, on the other hand, often leads to satellite disputes about how the tribunal should be formed before the real issues are even heard. Parties negotiating a contract are well advised to give the dispute resolution clause the same attention as the commercial terms, because it is the clause they will rely on precisely when the relationship has broken down.

Key Takeaways

An arbitration notice under Section 21 is the formal trigger that commences arbitration. Proceedings usually begin on the date the respondent receives the notice. The notice must clearly invoke the arbitration clause, describe the dispute and call for a reference. If no arbitrator is appointed within thirty days, a party can move the court under Section 11. Keep proof of service, mind limitation, and check that the dispute is arbitrable.
