Quick answer

An arbitration clause in your terms of service says users must bring disputes to a private arbitrator instead of a court. A class action waiver says they can only bring claims for themselves, not as part of a group. Together they are meant to stop a class action from being filed against your company.

In the United States, courts generally enforce both when the user clearly agreed to the terms and the clause is fair. The Supreme Court held in AT&T Mobility v. Concepcion (2011) that federal law protects class waivers inside arbitration agreements. Outside the US the picture is very different. In the EU, the UK and India, a clause that forces consumers into arbitration is weak or unenforceable, and class waivers are a US idea that most other systems don’t recognise.

The catch for companies is mass arbitration. If thousands of users file individual claims at once, you may owe more in arbitration fees than a class action would have cost. A good clause in 2026 is no longer “arbitrate everything, no class actions”. It is a short, fair dispute process that also deals with mass filings.

What these clauses actually do

People use these terms loosely, so here is what each one means in a terms of service.

Term	What it does
Arbitration clause	Sends disputes between the user and your company to an arbitrator, not a judge or jury
Class action waiver	Stops a user from suing, or joining a lawsuit, as part of a group
Jury waiver	Gives up the right to a jury trial for claims that do end up in court
Delegation clause	Says the arbitrator, not a court, decides whether the clause is valid and what it covers
Opt-out right	Lets a user reject arbitration within a set time, usually 30 days, by emailing you
Small claims carve-out	Allows either side to use small claims court instead of arbitration
Informal dispute resolution	Requires a written notice and a short negotiation period before anyone files
Mass arbitration provisions	Rules for handling many similar claims at once (batching, test cases, fee handling)

They often appear together in one “Dispute Resolution” section, which is why people call it “the arbitration and class waiver clause”. They are separate legal tools, and each can fail on its own.

If you’re new to how the whole document fits together, start with our guide to what terms and conditions are. This article goes deep on one section.

Should your terms include one?

There is no universal answer. The clause suits some businesses and creates problems for others.

Why companies add them

They can cut the risk of a large US class action, which is expensive even when the claim is weak.
Arbitration is private. Disputes and outcomes don’t appear on a public court docket.
It can be faster and cheaper than court for a single dispute.
Investors and enterprise customers sometimes expect to see them in consumer-facing products.

Why some companies shouldn’t

Mass arbitration. When claims are filed one by one, you pay fees on each. This tactic has hurt companies that adopted arbitration clauses with no plan for it.
Weak enforceability. A badly written clause can be struck down entirely and give you the worst of both worlds: no arbitration and a damaged reputation.
Little benefit outside the US. If your users are mostly in India, the UK or the EU, a class waiver adds almost nothing, and a forced arbitration clause may be unenforceable against consumers.
Business customers. In B2B deals the clause is usually negotiated, with a named institution and seat, rather than imposed through click-through terms.
Trust. Some consumers and journalists react badly to forced arbitration.

A simple way to decide

Your situation	Likely approach
Consumer app or marketplace with many US users	Consider arbitration with a class waiver, opt-out and mass arbitration protocol
Self-serve SaaS with small business users in the US	Arbitration may fit, but weigh the mass arbitration risk
Enterprise SaaS sold on negotiated contracts	Use a negotiated dispute clause, not click-through arbitration
Users mainly in India, the UK or the EU	Prefer courts or consumer forums, with a clear governing-law clause
Global product with a US and non-US mix	Use a US clause with a regional carve-out for consumers elsewhere
Early-stage with few users and little class-action exposure	Keep it simple. You can add arbitration later for new users, with proper notice

Are they enforceable? Two questions every court asks

When a user challenges the clause, a US court will usually ask two things in order.

1. Did the user actually agree to it?

An arbitration clause is a contract term, so it only binds someone who accepted it. This is where many clauses fail before their content is even read.

Clickwrap works best. The user ticks a box or clicks a button next to a clear statement that they agree to the terms, with a link. Courts regularly enforce these. In Meyer v. Uber (2d Cir. 2017), a sign-up screen with a clear notice and link was enough.
Browsewrap is risky. A link in a website footer saying “by using this site you agree” often fails. Users who downloaded software without seeing the terms weren’t bound.
Notice must be reasonable. In Berman v. Freedom Financial Network (9th Cir. 2022), a sign-up page that made the terms hard to notice meant no agreement formed.
Keep records. If a user denies agreeing, you need logs showing the version, the screen and the time they accepted.

Our terms and conditions drafting page covers clickwrap vs browsewrap in more detail. For arbitration clauses, the simple rule is to put the user’s agreement to dispute resolution in front of them, not buried at the bottom of a long page.

2. Is the clause fair?

Even if the user agreed, a court can refuse to enforce an arbitration clause that is unconscionable, meaning unfairly one-sided in how it was presented and in what it says.

Courts have objected to:

clauses that let only the company bring court claims while forcing users into arbitration,
fees so high that a user can’t afford to start,
a company-chosen forum far from the user,
rules that bar discovery or limit how a claim can be presented,
terms changed after the fact and applied to existing disputes,
a short deadline to file a claim.

The key US cases, in plain terms

Case	What it means for your clause
AT&T Mobility v. Concepcion (US Supreme Court, 2011)	Federal law (the Federal Arbitration Act) overrides state rules that ban class waivers in arbitration agreements
American Express v. Italian Colors (US Supreme Court, 2013)	A class waiver can be enforced even if an individual claim costs more than it could ever win
McGill v. Citibank (California Supreme Court, 2017)	A clause that waives the right to seek public injunctive relief in any forum is unenforceable in California, so carve it out
Heckman v. Live Nation (9th Cir. 2024)	A badly designed mass arbitration process made the entire arbitration agreement unconscionable

Courts interpret these rules differently across states and circuits, and the law keeps moving. Treat this as a map, not a guarantee.

Mass arbitration: the risk that changed how these clauses are written

For years, class waivers worked as intended. Users couldn’t bring class actions, and few filed individual claims because each one cost time. Plaintiffs’ firms found a workaround. They recruit hundreds or thousands of users and file individual arbitration demands all at the same time. Each claim triggers filing fees and arbitrator fees that fall mostly on the company. The total can exceed what a class action would have cost, which puts pressure on the company to settle.

How companies respond in their terms

Tool	What it does	Caution
Pre-filing notice and informal negotiation	Requires a written notice with the user’s details and a 30-60 day talk before arbitration	Must be genuinely mutual and workable
Batching	Groups similar claims so they’re handled together	Courts in several US cases have allowed batching, but results vary
Bellwether (test case) process	Arbitrates a small number of claims first and uses results to guide settlement of the rest	Can fail if it binds people without giving them a voice
Provider rules	Names an arbitration provider (for example AAA or JAMS) whose rules have mass arbitration procedures	Check the current version of the rules, as providers change them
Fee provisions	Spells out who pays and when	Unfair fee terms can sink the clause
Requirements for a valid demand	Asks for the user’s identity, account details and a description of the claim	Don’t make the bar so high it blocks real claims

What Heckman v. Live Nation teaches

In 2024, the Ninth Circuit refused to enforce Ticketmaster’s arbitration clause. The court found that the company’s mass arbitration process, run by a provider called New Era ADR, was unfair. It held claimants to the results of test cases they could not take part in, limited discovery, let the provider override arbitrator disqualification, and gave only one side a meaningful appeal. Because the delegation clause itself was unconscionable, the court refused to rescue the rest of the agreement.

The lesson isn’t “don’t use mass arbitration protocols”. Some later US district court decisions have enforced carefully drafted batching and bellwether terms. The lesson is that a protocol designed only to protect the company is a protocol that puts the whole clause at risk. Make it mutual and make it fair.

Fees and who pays

Two recent developments are worth knowing. Several US appeals courts (including the Second Circuit in Frazier v. X Corp., 2025) have said a court cannot force a company to pay arbitration fees under the Federal Arbitration Act, while California’s SB 707 now sets short deadlines for businesses to pay and allows consequences if they don’t. If you rely on arbitration, budget for the fees and have a plan for paying them on time.

Outside the US: the same clause, a very different result

If you serve users in several countries, assume that mandatory consumer arbitration and class waivers don’t travel. Here is a rough guide.

Place	What to know
India	A consumer can still go to a consumer commission even if the contract has an arbitration clause (Emaar MGF Land Ltd. v. Aftab Singh, Supreme Court, 2018). The Consumer Protection Act, 2019 also lets one or more consumers file on behalf of many with the same interest, and the State and National Commissions can declare unfair contract terms void. Arbitration agreements must be in writing under Section 7 of the Arbitration and Conciliation Act, 1996, and electronic exchanges can qualify.
UK	Under the Consumer Rights Act 2015, a term that requires a consumer to take disputes exclusively to arbitration can be unfair and not binding on the consumer.
EU	The Unfair Terms Directive (93/13/EEC) lists terms that hinder a consumer’s right to go to court, including forcing disputes to arbitration, as potentially unfair. Collective redress is available through representative actions. In Germany, consumer arbitration agreements have strict form rules.
Canada	The Supreme Court struck down an arbitration clause in Uber Technologies v. Heller (2020) because of the cost barrier, and Quebec’s consumer law limits mandatory consumer arbitration.
UAE and other B2B-focused markets	Arbitration is common between businesses. Choose the seat and institution deliberately. See our guide to DIFC and DIAC arbitration clauses.

What this means in practice: if your product reaches consumers in these places, your terms should say that nothing removes consumer rights that can’t be waived by law. A “regional addendum” for non-US users is a common solution.

For the business-to-business side, our comparison of arbitration vs litigation in cross-border contracts and mediation vs arbitration vs litigation explain how to choose a forum.

What a well-drafted clause contains

Here is a checklist you can hold your own terms up against.

A clear scope. What disputes are covered, and which ones aren’t.
Informal resolution first. A written notice process and a fixed period to settle.
A named provider and rules. For example AAA or JAMS consumer rules, with the right to use the current version.
A reasonable place to arbitrate. Remote hearings or the user’s home area, not a distant city.
Fair fee terms. Who pays what, with company-paid fees for small consumer claims.
A small claims carve-out. Either side can use small claims court.
Both sides bound. Avoid terms that exempt only the company’s claims from arbitration. If you want to protect IP, consider a narrow mutual carve-out.
A class waiver, plus a fallback. If the waiver is struck down, say what happens next.
A public injunctive relief carve-out for California users.
An opt-out window. It strengthens enforceability and reduces the “adhesion contract” argument.
A mass arbitration protocol that is mutual, balanced and workable.
A good severability clause, so one bad part doesn’t take down the rest.
A delegation clause, written clearly and kept separate from the rest.
A rule for future changes. Say how you will change this section and that changes won’t apply to disputes already started.
A statement about non-waivable consumer rights for users outside the US.

Sample wording

These are illustrations for a US-facing consumer product. A lawyer should adapt them for your service and your users’ locations.

Informal resolution:

Before starting any arbitration, you and [Company] each agree to try to resolve the dispute informally. You must send a written notice to [email] describing the dispute, your account details and the relief you want. We will do the same if we raise a dispute. If the dispute is not resolved within 45 days of the notice, either of us may start arbitration.

Arbitration agreement with carve-outs:

Except as stated below, you and [Company] agree that any dispute arising out of or relating to these Terms or the Services will be resolved by binding individual arbitration under the [AAA Consumer Arbitration Rules] in effect when the demand is filed. Either party may instead bring an individual claim in small claims court if it qualifies. Either party may seek injunctive relief in court to stop infringement or misuse of intellectual property.

Class action waiver with fallback:

You and [Company] agree that each may bring claims against the other only in an individual capacity and not as a plaintiff or class member in any purported class, collective or representative proceeding. If this waiver is found unenforceable for a particular claim, that claim will proceed in court and not in arbitration, and the remainder of this section will continue to apply to all other claims.

Opt-out:

You may opt out of this arbitration agreement by emailing [email] within 30 days of first accepting these Terms, stating your name and account email and that you opt out. If you opt out, the rest of these Terms still apply.

Public injunctive relief (California):

Nothing in this section prevents you from seeking public injunctive relief in court, and any such claim will be stayed pending the arbitration of your other claims, to the extent required by applicable law.

Rights that cannot be waived:

If you are a consumer residing outside the United States, nothing in these Terms removes mandatory consumer protection rights or the right to bring a claim in the courts of your country of residence where applicable law gives you that right.

Getting the user’s agreement properly

A well-drafted clause still fails if the user never agreed to it.

Use clickwrap at sign-up. A checkbox or “I agree” button beside a link to the terms.
Make the clause easy to find. Use a heading and, ideally, a short summary at the point of acceptance. Bold the arbitration and class waiver language if it sits in a long document.
Log acceptances. Store the version, date, time and user ID.
Don’t spring changes on existing users. If you add arbitration later, give clear notice and a chance to opt out. Courts have been critical of changes applied quietly or to claims already in progress.
Give a copy. Keep a link to the current terms and the archive of earlier versions in the footer and account area.

Related documents should say the same thing as your terms. Your privacy policy, any acceptable use policy, end user licence agreement and app store terms should not contradict the dispute clause.

Common mistakes in terms of service

Copying a dispute clause from a big company. Their clause was built for their size, their users and their lawyers’ risk appetite. It may expose a smaller company to mass arbitration it can’t afford.

Using a US-only clause for a global product. A user in the EU, UK or India isn’t bound by terms that override consumer protection law, and including them can make the whole section look overreaching.

Making the process one-sided. Courts react to clauses that bind users while leaving the company free to sue, or that give only the company control over procedure.

Forgetting mass arbitration. A bare “all disputes go to arbitration” clause with no protocol is the version most exposed to this tactic.

Burying the clause. An arbitration clause hidden in a footer link invites an argument that no agreement was formed.

Treating the class waiver as a shield against regulators. It doesn’t stop government agencies, such as the FTC or a state attorney general, from enforcing the law.

Changing the clause with no notice. Retroactive changes are a recurring reason courts refuse to enforce.

Ignoring the rest of the document. Your limitation of liability and indemnity terms interact with the dispute clause. Draft them together.

Where this fits for startups and platforms

For a SaaS product or marketplace, the dispute clause sits alongside the other core documents. Our checklists for a US SaaS startup and a US e-commerce business show which documents you need and in what order. For subscription software specifically, see SaaS agreement drafting. If your platform sells in India, our e-commerce lawyer in India page covers the local rules, and our overview of the US legal system explains how state and federal courts interact.

If a dispute has already started, a clause is no longer the question. Negotiation and mediation support is often the faster route, and online dispute resolution is worth considering for small cross-border claims.

Frequently asked questions

Are arbitration clauses in terms of service enforceable?

In the US, usually yes, if the user clearly agreed to the terms and the clause is fair. Courts refuse to enforce clauses that are hidden, one-sided, or too costly for the user. Outside the US, forced arbitration against consumers is often weak or unenforceable.

Are class action waivers enforceable?

In the US, a class waiver inside an arbitration clause is generally enforceable under the Federal Arbitration Act (AT&T Mobility v. Concepcion, 2011). Some claims, such as public injunctive relief in California, can’t be waived. Many other countries don’t recognise class waivers in consumer contracts.

Does my SaaS or app need an arbitration clause?

Not necessarily. It can reduce class action exposure for a consumer-facing US product, but it brings mass arbitration risk and little benefit for users outside the US. For business customers, a negotiated dispute clause is usually better than click-through arbitration.

What is mass arbitration?

It’s when many users file individual arbitration demands at once, so the company has to pay fees on each. Terms now often include informal dispute steps, batching or bellwether processes, and clear fee rules to manage it.

Can users opt out of arbitration?

Only if your terms give them that right. An opt-out window, typically 30 days, is a common feature that supports enforceability.

What is a delegation clause?

It’s a clause saying the arbitrator, not a court, decides whether the arbitration agreement is valid and what it covers. It needs to be clear and separate, and an unfair delegation clause can bring down the whole agreement, as in Heckman v. Live Nation.

Can I add an arbitration clause to my existing terms?

You can change terms, but you should give clear notice and ideally an opt-out, and make clear the change doesn’t apply to disputes already started. Courts have refused to enforce changes applied retroactively or without proper notice.

Does a class action waiver stop regulators?

No. Government agencies such as the FTC or a state attorney general aren’t bound by a private contract between you and your users.

Does an arbitration clause work for users in India?

A consumer in India can still approach a consumer commission despite an arbitration clause (Emaar MGF Land Ltd. v. Aftab Singh, 2018), and class waivers have no real place there. The Consumer Protection Act, 2019 also allows representative complaints. For Indian users, a clear governing law and a fair, accessible process work better than forced arbitration.
