In India, institutional vs ad hoc arbitration comes down to who administers the process. In institutional arbitration, a specialised body such as the Mumbai Centre for International Arbitration (MCIA) or the Delhi International Arbitration Centre (DIAC) administers the dispute under its published rules and fee schedule. In ad hoc arbitration, the parties run the process themselves, fixing their own procedure, timelines and the arbitrator's fees without any administering institution. Both are fully valid under the Arbitration and Conciliation Act, 1996 (the "A&C Act"); the choice mainly affects cost, procedural certainty and how much hand-holding you get.

This guide explains the differences between institutional and ad hoc arbitration, the typical costs of each, and the practical factors that help you decide which suits your dispute. It is written for businesses, founders and individuals in India who are drafting an arbitration clause or already facing a dispute.
What is arbitration under the A&C Act 1996?
Arbitration is a private dispute-resolution mechanism in which parties agree to have their dispute decided by one or more arbitrators instead of the civil courts. The award is binding and enforceable like a court decree. The governing statute is the Arbitration and Conciliation Act, 1996, which has been amended several times, notably in 2015, 2019 and 2021, to speed up the process and reduce court interference.
A few sections are worth knowing before you read further:
- Section 7, defines an arbitration agreement (must be in writing).
- Section 11, appointment of arbitrators, including by the Supreme Court or High Court where parties cannot agree.
- Section 9, interim measures by a court (before, during or after the arbitration, until the award is enforced).
- Section 29A, time limit for making an arbitral award (generally 12 months from completion of pleadings, extendable by six months by party consent, and beyond that only by court order).
- Section 31(8) and Section 38, costs and deposits.
- Section 34, application to set aside an award.
- Section 42A, confidentiality. The arbitrator, the arbitral institution and the parties must maintain confidentiality of the proceedings, except the award where disclosure is needed for implementation and enforcement. This duty applies whether the arbitration is institutional or ad hoc.
These section numbers are from the A&C Act 1996 as currently amended. Arbitration law is amended frequently, so always confirm the current text before relying on a section.
Institutional vs ad hoc arbitration in India: the core difference
The single defining difference is administration.
- Institutional arbitration. An arbitral institution supervises the case. It supplies the rule book, maintains a panel of arbitrators, fixes and collects fees, manages timelines, provides hearing facilities and often scrutinises the draft award before it is signed. Examples in India include the Mumbai Centre for International Arbitration (MCIA), the Delhi International Arbitration Centre (DIAC), the India International Arbitration Centre (IIAC) in Delhi, and the Indian Council of Arbitration (ICA). International institutions such as the SIAC (Singapore) and ICC are also widely chosen in cross-border contracts.
- Ad hoc arbitration. No institution is involved. The parties (and the tribunal) design the procedure themselves, agree the arbitrator's fees directly, and rely on the A&C Act and the courts to fill gaps (for example, a court appoints the arbitrator under Section 11 if the parties deadlock). Ad hoc arbitration has historically been the most common form in India, especially in domestic commercial and construction disputes.
Everything else, including appointment mechanics, cost, speed and procedural discipline, flows from that one difference.
Administration is the whole distinction, and here is what it means on each side.
Institutional: an administrator
The institution supplies the rule book, maintains a panel of arbitrators, fixes and collects fees, manages timelines, provides hearing facilities and often scrutinises the draft award.
Indian institutions
MCIA in Mumbai, DIAC and the India International Arbitration Centre in Delhi, and the Indian Council of Arbitration. SIAC and ICC are common in cross-border contracts.
Ad hoc: parties in charge
No institution is involved. The parties and the tribunal design the procedure, agree the arbitrator's fees directly, and rely on the Act and the courts to fill gaps.
Section 11 fallback
In ad hoc arbitration, where the parties deadlock on who should decide the dispute, a court appoints the arbitrator under Section 11 before anything else can start.
Key takeaway. You do not choose between institutional and ad hoc arbitration when the dispute erupts. You choose it years earlier, when someone drafts the arbitration clause in the contract. By the time there is a dispute, the clause is fixed and you live with whichever route it selected. Treat the clause as the single most consequential paragraph in the agreement, not as boilerplate to be copied from the last contract.
Differences between institutional and ad hoc arbitration
The table below summarises the practical differences. Read it as a starting point, not a rule: a well-drafted ad hoc clause can borrow institutional discipline (for example by adopting the UNCITRAL Arbitration Rules), and a badly run institutional case can still drag.
| Feature | Institutional arbitration | Ad hoc arbitration |
|---|---|---|
| Administering body | Yes, institution manages the case | No, parties manage it themselves |
| Rules | Institution's published rules (for example, MCIA Rules, DIAC Rules) | Parties draft their own, or adopt UNCITRAL Rules; otherwise A&C Act defaults apply |
| Appointment of arbitrator | From institution's panel or by the institution | By party agreement, failing which a court under Section 11 |
| Fees | Published, schedule-based, usually tied to dispute value | Negotiated directly with the arbitrator(s); can vary widely |
| Administrative support | Hearing rooms, case managers, secretariat | Parties arrange everything |
| Timelines | Institutional rules plus Section 29A | Section 29A plus whatever parties agree |
| Scrutiny of award | Many institutions review the draft award for defects | None, relies on the tribunal alone |
| Predictability | Higher, settled rules and precedents of administration | Lower, depends on how well the clause is drafted |
| Best suited to | Complex, high-value or cross-border disputes; parties who want structure | Simpler, lower-value or domestic disputes; parties comfortable self-managing |
Cost of institutional vs ad hoc arbitration
Cost is usually the first question clients ask, and the answer is genuinely that it depends.
Institutional arbitration charges an administrative fee on top of the arbitrators' fees, and both are typically set by a published schedule linked to the amount in dispute. This makes costs transparent and predictable at the outset, because you can read the fee table before you sign the clause. For smaller disputes the administrative fee can feel disproportionate; for large or complex matters it is often money well spent because the institution absorbs scheduling, document handling and award scrutiny.
Ad hoc arbitration has no administrative fee, which can make it cheaper on paper. However, arbitrators' fees are negotiated directly and are not capped by an institution. For domestic ad hoc arbitrations, the Fourth Schedule to the A&C Act 1996 provides a model fee scale linked to the sum in dispute, which courts and tribunals often use as a reference, though the Supreme Court has clarified that this schedule is not automatically mandatory in every case. Ad hoc costs can also creep up through procedural disputes, repeated court applications (for appointment under Section 11, interim relief under Section 9, or extensions under Section 29A), and the absence of a case manager to keep things moving.
| Cost element | Institutional | Ad hoc |
|---|---|---|
| Administrative / institution fee | Yes, per published schedule | None |
| Arbitrator fees | Per institution schedule (predictable) | Negotiated; Fourth Schedule often used as a guide |
| Venue / hearing facilities | Usually provided | Arranged and paid for separately |
| Hidden cost risk | Lower (managed process) | Higher (procedural disputes, court applications) |
| Cost certainty upfront | High | Variable |
A common misconception is that ad hoc is always cheaper. For a straightforward, low-value dispute it often is. For a tangled, high-stakes matter, the structure of an institution frequently saves more than it costs.
When to choose institutional arbitration
Institutional arbitration tends to be the better fit when:
- The dispute is high-value or complex (multiple parties, technical evidence, large documents).
- The contract is cross-border and you want neutral, internationally recognised rules and enforceability comfort.
- You want predictable, scheduled costs and a fixed rule book agreed in advance.
- The parties have a history of distrust and you need a neutral body to handle appointments and logistics.
- You value award scrutiny to reduce the risk of a defect that invites a Section 34 challenge.
When ad hoc arbitration makes sense
Ad hoc arbitration can be the sensible choice when:
- The dispute is domestic and relatively simple or moderate in value.
- Both parties are cooperative and comfortable agreeing procedure between themselves.
- You want to avoid an administrative fee and the matter does not need institutional logistics.
- You can rely on experienced counsel and a competent sole arbitrator to keep the process disciplined.
The biggest risk with ad hoc arbitration is a poorly drafted clause. If the clause is vague on the number of arbitrators, the seat, the language or the appointment mechanism, parties end up in court under Section 11 before the arbitration even begins, wiping out the cost savings.
Common mistake. Writing an ad hoc clause with no working appointment mechanism. Section 11 of the A&C Act runs on thirty-day windows: if the parties fail to agree on a sole arbitrator within thirty days of a request, or two appointed arbitrators fail to agree on a presiding arbitrator within thirty days, the appointment has to be made by the Supreme Court or the High Court on application. That court detour can add months and a full round of professional fees before a single pleading is filed. Name the appointing authority in the clause, or name the institution, and you never see the inside of a Section 11 court.
Drafting tip: the arbitration clause decides everything
Whether you go institutional or ad hoc, the arbitration clause in your contract does the heavy lifting. A sound clause specifies the seat (legal place) of arbitration, the venue, the governing law, the number and method of appointing arbitrators, the language, and, for institutional arbitration, names the institution and adopts its rules. Vague clauses that say only that disputes shall be referred to arbitration are a frequent source of avoidable litigation. This is closely connected to careful contract drafting generally, the same discipline that protects intellectual property and commercial rights in agreements.
After the award: the deadlines that catch people out
The route you chose matters less than the clock once an award is signed. Two provisions decide what happens next, and both are unforgiving.
Section 34(3) sets the challenge window. An application to set aside an award may not be made after three months have elapsed from the date on which the applicant received the award, or, if a request for correction or interpretation was made under Section 33, from the date that request was disposed of. The proviso lets the court entertain the application within a further thirty days if it is satisfied the applicant was prevented by sufficient cause, but expressly not thereafter. Unlike ordinary limitation, that outer limit is hard.
Section 36 governs enforcement. Once the time for a Section 34 application has expired, the award is enforced under the Code of Civil Procedure, 1908 as if it were a decree of the court. Critically, Section 36(2) provides that merely filing a Section 34 application does not by itself make the award unenforceable. The award is stayed only if the court grants a stay under Section 36(3) on a separate application made for that purpose, and where the award is for payment of money the court must have regard to the principles governing stay of a money decree.
Deadline warning. Three months from receipt of the award under Section 34(3), plus at most a further thirty days on sufficient cause, and not one day beyond. And filing that challenge does not freeze the award: under Section 36(2) you must file a separate stay application and actually obtain an order, or the successful party can start executing against your assets while your challenge is still pending. Diarise the date you received the award, not the date it was signed.

Frequently Asked Questions
What is the main difference between institutional and ad hoc arbitration in India?
The main difference is administration. In institutional arbitration, an arbitral institution manages the case under its published rules and fee schedule. In ad hoc arbitration, the parties run the process themselves with no administering institution, relying on their own agreed procedure and the Arbitration and Conciliation Act, 1996.
Is ad hoc arbitration cheaper than institutional arbitration?
Not always. Ad hoc arbitration avoids an institution's administrative fee, so it can be cheaper for simple, low-value disputes. But arbitrator fees are negotiated directly and uncapped, and procedural disputes or court applications can raise the total. For complex or high-value matters, institutional arbitration is often more cost-effective overall.
Which arbitral institutions operate in India?
Indian institutions include the Mumbai Centre for International Arbitration (MCIA), the Delhi International Arbitration Centre (DIAC), the India International Arbitration Centre (IIAC) and the Indian Council of Arbitration (ICA). International institutions such as SIAC and ICC are also commonly chosen in cross-border Indian contracts.
How long does arbitration take in India?
Under Section 29A of the Arbitration and Conciliation Act, 1996, an award in a matter other than an international commercial arbitration is to be made within twelve months from the date of completion of pleadings under Section 23(4). The parties may by consent extend that by up to a further six months. If the award is still not made, the arbitrator's mandate terminates unless the court extends the period, and the court may reduce the arbitrator's fees where the delay is attributable to the tribunal. Confirm the current text before relying on it.
Who appoints the arbitrator in ad hoc arbitration?
The parties appoint the arbitrator by agreement. If they cannot agree, either party may apply to the Supreme Court (for international commercial arbitration) or the relevant High Court (for domestic arbitration) under Section 11 of the Arbitration and Conciliation Act, 1996, which will then make the appointment.
When should I choose institutional arbitration over ad hoc?
Institutional arbitration generally suits high-value, complex or cross-border disputes, parties wanting predictable scheduled costs, and situations where neutral administration and award scrutiny reduce risk. Ad hoc arbitration suits simpler, domestic or moderate-value disputes between cooperative parties who are comfortable managing the process themselves.
Is an arbitration clause mandatory to arbitrate?
Yes. Under Section 7 of the Arbitration and Conciliation Act, 1996, arbitration requires a written arbitration agreement, usually a clause in the contract. Without a valid arbitration agreement, a dispute cannot be referred to arbitration and would ordinarily go to the civil courts.
Is arbitration confidential in India?
Section 42A of the Arbitration and Conciliation Act, 1996 requires the arbitrator, the arbitral institution and the parties to maintain confidentiality of all arbitral proceedings, with an exception for the award where disclosure is necessary for its implementation and enforcement. The duty applies to ad hoc arbitrations as much as institutional ones.
How long do I have to challenge an arbitral award?
Section 34(3) allows three months from the date you received the award, or from the date a Section 33 request was disposed of. The court may allow a further thirty days if satisfied there was sufficient cause, but not beyond that.
Does filing a Section 34 challenge stop the other side from enforcing the award?
No. Section 36(2) makes clear that filing the application does not by itself render the award unenforceable. You must make a separate application for stay and obtain an order under Section 36(3), which the court may grant on conditions.
