Arbitration Mechanism in Stock Exchanges: NISM Series VII Notes

Updated 11 October 2026

Stock exchange arbitration is a formal, exchange-run process for settling disputes between an investor and a trading member over exchange trades. You file a claim within the time limit, the exchange appoints arbitrators (one or three, based on claim size), and they give a binding award. An appeal is possible.

Understand Arbitration Mechanism in Stock Exchanges

Arbitration is a way to settle a dispute outside court. A neutral person, the arbitrator, hears both sides and gives a decision called an award. Stock exchanges such as NSE and BSE run an arbitration system for disputes that arise from trades done on the exchange.

It is used when ordinary grievance handling fails. An investor first complains to the broker, then to the exchange through the grievance route (SCORES or the exchange's own channels). If the matter is still not settled, the investor can go for arbitration. Conciliation or mediation may be tried before or alongside it, as the exchange rules and SEBI circulars provide.

The parties are usually a client (investor) and a trading member. The dispute must relate to trades or dealings on that exchange. Disputes outside exchange trades, such as a pure banking or off-market matter, do not fit here.

The exchange keeps a panel of approved arbitrators. The parties do not pick their own. The exchange appoints from the panel. For smaller claims one arbitrator is enough. For larger claims a panel of three is used. Rules on claim limits, time limits, fees and appeals are set by SEBI circulars and exchange bye-laws, and the NISM workbook tests the main ones.

The award is binding. If a party is unhappy, it can appeal within a short time to an appellate arbitration panel of the exchange. After that, the remaining route is the court under the Arbitration and Conciliation Act, 1996. Exam questions test the numbers: time limits, claim size and number of arbitrators. Check each figure against your current NISM workbook and the current SEBI master circular.

Key formulas to remember

Limitation period for filing: Claim must be filed within the period allowed under the Limitation Act: 3 years from the date of the transaction or event giving rise to the dispute; The period is computed under the Limitation Act rules. A claim filed after this is generally time-barred, though delay may be condoned in appropriate cases under the Limitation Act provisions. Check the exact wording in the current NISM workbook and SEBI circulars.
Number of arbitrators: Claim up to ₹25,00,000 → sole arbitrator; claim above ₹25,00,000 → panel of three arbitrators (threshold to be verified); ₹25 lakh is the threshold as generally taught under the SEBI and exchange framework. Verify it against the current SEBI master circular, exchange bye-laws and the NISM workbook before you treat it as a fixed exam figure. The threshold applies to the claim amount. Counter-claims are considered with the claim.
Appointment: Arbitrators are appointed by the exchange from its approved panel; Parties do not choose the arbitrator.
Award timeline: Award timelines are fixed in the SEBI master circular and exchange rules (generally taught as 3 months from the date the arbitrator(s) enter upon the reference, and 3 months for the appellate panel). Verify before relying on them.; Do not treat these timelines as confirmed exam figures until you check them against the current SEBI master circular and exchange rules. The tribunal and the appellate panel can extend the period for stated reasons.
Appeal: Appeal to the appellate panel within 30 days of receiving the award; The appeal period is linked to the Limitation Act in the SEBI circular. The size of the appellate panel depends on the amount involved, so check the circular and exchange rules for the panel size. The appellate arbitrators are different from the original ones.
Fees: Fees and deposits are as per the exchange's schedule, linked to the claim amount; Do not memorise a fee amount unless the workbook gives it. Know that fees rise with claim size.

How to solve Arbitration Mechanism in Stock Exchanges questions

Use this method for any question on exchange arbitration. Most questions turn on one number or one party. Use the figures as given in your current NISM workbook.

1Identify the dispute: is it between a client and a trading member over an exchange trade? If not, arbitration may not apply.
2Check the time: count from the date of the transaction or event giving rise to the dispute, using Limitation Act rules. More than 3 years is generally time-barred, though delay may be condoned in appropriate cases.
3Look at the claim amount and compare it with the sole-arbitrator threshold in the current SEBI master circular and your workbook (generally taught as ₹25 lakh). Up to the threshold means one arbitrator. Above it means three. Do not rely on this figure until you have verified it.
4Note who appoints: the exchange, from its approved panel, not the parties.
5Check the stage: award, then appeal within 30 days to the appellate panel, then court under the Arbitration and Conciliation Act. The appellate panel size depends on the amount involved.
6Match the answer to the exact wording of the options. Eliminate options with parties choosing arbitrators or with wrong time limits.

Quickest way: Three-number recall

When to use it: Use when you have under a minute and the question asks for a limit, count or timeline.

Recall 3 / 25 / 30: 3 years to file (from the transaction or event), the ₹25 lakh claim threshold as generally taught (verify it against the current circular and workbook), and 30 days to appeal.
Recall 1 or 3: sole arbitrator up to the threshold, three above it.
Do not add the award timeline to this shortcut until you have verified it in the current SEBI master circular and exchange rules.
Pick the option that matches. Reject any option where the investor chooses the arbitrator.

Common mistakes in Arbitration Mechanism in Stock Exchanges

Saying the time limit to file is 1 year or 6 months
Shorter periods are easy to guess, or get mixed up with other short deadlines in grievance handling. The arbitration filing limit follows the Limitation Act, so it is not a short period.
Fix: Link the filing limit to the Limitation Act: 3 years from the date of the transaction or event giving rise to the dispute.
Using three arbitrators for every claim
Assuming a panel is always more formal.
Fix: Check the amount against the sole-arbitrator threshold (generally taught as ₹25 lakh). Claims up to it use a sole arbitrator. Three arbitrators are for larger claims. Verify the threshold in the current circular and your workbook.
Thinking the investor and broker pick the arbitrators
Confusing exchange arbitration with private arbitration.
Fix: Remember the exchange appoints from its approved panel.
Treating the award as final with no appeal
Forgetting the appellate panel.
Fix: Remember the appeal to the appellate panel within 30 days, before going to court.
Counting the 3 years from the filing of the complaint with the broker
Mixing up the stages of grievance redressal.
Fix: Count from the date of the transaction or event giving rise to the dispute, not from the date of any earlier complaint.
Applying arbitration to any investor dispute
Ignoring the scope.
Fix: Arbitration covers disputes over dealings on the exchange between the client and the member. Check the scope first.

Worked examples

Example 1

A client has a ₹18,00,000 claim against a trading member for a disputed trade on an exchange, filed in time. Taking the sole-arbitrator threshold as ₹25,00,000 (verify against the current circular and your workbook), how many arbitrators will the exchange appoint, and who appoints them?

Show the solution

Step 1: The claim is between a client and a trading member over an exchange trade, so exchange arbitration applies.
Step 2: Compare the claim with the threshold of ₹25,00,000 used in this example: ₹18,00,000 is below it.
Step 3: Claims up to the threshold go to a sole arbitrator.
Step 4: The appointment is made by the exchange from its approved panel, not by the parties.

Answer: One sole arbitrator, appointed by the exchange from its panel.

Example 2

A disputed trade was executed on 10 January 2021. The client files for arbitration on 15 February 2024. Is the claim within the time limit?

Show the solution

Step 1: The claim must be filed within the Limitation Act period, which is 3 years from the date of the transaction or event giving rise to the dispute.
Step 2: Counting under the Limitation Act, the day of the event is excluded, and 3 years from 10 January 2021 ends on 10 January 2024.
Step 3: The filing date, 15 February 2024, is after 10 January 2024.
Step 4: The claim is therefore generally time-barred, unless the delay is condoned in appropriate circumstances.

Answer: No. The claim was filed after the 3-year limit, so it is generally time-barred unless the delay is condoned.

Exam tips

Check the numbers 3 years and 30 days in your workbook, and verify the claim threshold (generally taught as ₹25 lakh) against the current circular. Questions often change only one of them in the wrong options.
On negative-marked papers, skip only if you cannot place the stage (filing, appointment, award, appeal). Most questions are direct recall.
Read the claim amount carefully. A claim of exactly the threshold falls in the 'up to' group.
Watch for options saying parties select arbitrators. This is almost always the trap.
Check your latest NISM workbook for any revised limits, as SEBI circulars can change them.

Practice questions from Investor Grievances and Arbitration

Arbitration Mechanism in Stock Exchanges: frequently asked questions

What is the time limit for filing arbitration against a stock broker?

The claim must be filed within the Limitation Act period, which is 3 years from the date of the transaction or event giving rise to the dispute. After that it is generally time-barred, although delay may be condoned in appropriate cases. The count does not restart from any later complaint.

How many arbitrators are appointed in stock exchange arbitration?

Under the SEBI and exchange framework, one sole arbitrator is appointed for claims up to the threshold, generally taught as ₹25 lakh. A panel of three is appointed for claims above that. The exchange appoints them from its approved panel. Verify the threshold in the current SEBI master circular, exchange bye-laws and NISM workbook.

Can I appeal against an arbitration award?

Yes. You can appeal to the exchange's appellate arbitration panel within 30 days of receiving the award. This period is linked to the Limitation Act in the SEBI circular. The size of the appellate panel depends on the amount involved, so check the circular and exchange rules. After that, the court route under the Arbitration and Conciliation Act, 1996 remains.

Who can file for arbitration at NSE or BSE?

Clients can file against trading members, and members can file against clients, for disputes arising out of exchange trades. The dispute must relate to dealings on that exchange.
