An arbitration clause in a contract is enforceable under the Federal Arbitration Act as long as it rests on a valid contract and does not run afoul of ordinary defenses like fraud, duress, or unconscionability. That baseline is easy to state and hard to meet: most clauses that get struck down fail not because arbitration itself is disfavored, but because the drafter overreached on fees, scope, or visibility. The sections below walk through the choices that decide whether your clause survives a challenge.
The Legal Backbone
Section 2 of the FAA declares that a written arbitration agreement in a contract involving interstate commerce “shall be valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.”1Office of the Law Revision Counsel. 9 USC 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate Courts can still refuse to enforce a clause on general contract grounds, but they cannot single arbitration out for special hostility, and state laws that try to do so are preempted.2Justia Law. AT&T Mobility LLC v. Concepcion, 563 US 333 (2011)
One boundary worth flagging early: Section 1 of the FAA exempts “contracts of employment of seamen, railroad employees, or any other class of workers engaged in foreign or interstate commerce.”3Office of the Law Revision Counsel. 9 USC 1 – Definitions The Supreme Court has read this narrowly to cover workers who physically move goods or people across borders. If your contract is with that kind of worker, an arbitration clause will not be enforced under the FAA. State law can still validate the underlying contract, and state contract rules on formation, capacity, and consideration continue to govern whether any arbitration agreement exists in the first place.
The Core Drafting Decisions
Scope of Covered Disputes
Scope is the single most consequential choice. Broad language, typically “any dispute arising out of or relating to this agreement,” pulls in tort claims and statutory violations that touch the underlying relationship. Narrow language limits arbitration to defined categories such as payment disputes or breach of warranty and leaves everything else open to litigation. Ambiguity is expensive. If the parties disagree about whether a claim falls inside the clause, they end up in court fighting about the arbitration agreement before anyone reaches the actual dispute.
Provider and Rules
Most clauses name the American Arbitration Association or JAMS to administer the process. Naming a provider supplies a roster of qualified arbitrators and imports that organization’s procedural rules by default, which control evidence exchange, hearing scheduling, and fee allocation. Skip this step and a court can still appoint an arbitrator under the FAA, but you lose control over the framework and both sides lose the predictability that made arbitration attractive.
Number of Arbitrators and Location
One arbitrator is cheaper and faster. A three-person panel adds perspectives and is common in complex commercial disputes, but the cost scales quickly because every panelist bills for preparation and hearing time. For consumer and employment contracts, a single arbitrator is the standard choice.
Location shapes enforceability. A clause that forces a consumer in one state to travel across the country over a few hundred dollars invites an unconscionability challenge. Picking a forum convenient to the weaker party, or authorizing remote hearings, reduces that risk. The clause should also identify which state’s substantive law governs the underlying dispute; that is a separate question from the procedural rules of the arbitration itself.
Finality
State clearly that the arbitrator’s decision is binding and final. Under the FAA, judicial review of an award is limited to a handful of narrow grounds like fraud, arbitrator bias, or the arbitrator exceeding their authority.4Office of the Law Revision Counsel. 9 USC 10 – Vacation of Awards; Grounds; Rehearing An arbitrator can misread the law and the award still stands. Explicit finality language forecloses any later argument that the parties expected an appeal right.
Who Pays
Fee allocation is one of the most litigated features of any arbitration clause, and getting it wrong is one of the fastest routes to having the clause thrown out. Consumer-facing agreements that load costs onto the individual risk a finding of unconscionability. The major providers have addressed this through their own fee schedules. JAMS caps its consumer filing fee at $250, roughly equivalent to a court filing fee, with the business paying the remaining administrative and arbitrator costs.5JAMS. Consumer Arbitration Minimum Standards AAA’s consumer filing fee sits in the same range. In both systems the business bears the bulk of the financial burden for consumer disputes.
Handle “loser pays” language carefully. AAA’s consumer arbitration rules restrict arbitrators from reallocating fees to the consumer unless the claim was filed for harassment or is clearly frivolous.6Consumer Financial Protection Bureau. Arbitration Agreements Rule A clause that overrides this protection and threatens the consumer with the company’s legal fees will draw scrutiny from any reviewing court. The safe approaches are letting the provider’s fee rules control or stating outright that the business will bear all costs beyond the consumer’s initial filing fee.
Class Action Waivers
Many clauses require each party to bring claims only on an individual basis, with no class or collective proceedings. For businesses, this is often the single most valuable feature of the entire agreement. The Supreme Court has consistently enforced these waivers. AT&T Mobility v. Concepcion (2011) held that the FAA preempts state laws that would invalidate class action waivers in consumer arbitration agreements.2Justia Law. AT&T Mobility LLC v. Concepcion, 563 US 333 (2011) Epic Systems v. Lewis (2018) extended the rule to employment contracts, permitting employers to require individual arbitration even for wage-and-hour claims that would otherwise qualify for collective action under the Fair Labor Standards Act.7Supreme Court of the United States. Epic Systems Corp. v. Lewis, 584 US 497 (2018)
The practical effect is significant. If your clause includes a class waiver, the other party generally cannot bring or join a class proceeding even when their individual claim is too small to pursue alone. One federal carve-out applies to sexual assault and harassment claims, covered further down.
Delegation Clauses
By default, a court decides whether a particular dispute falls within the arbitration agreement. A delegation clause hands that threshold question to the arbitrator instead. The Supreme Court upheld this in Rent-A-Center v. Jackson (2010), treating the delegation provision as a separate, severable agreement under the FAA.8Legal Information Institute. Rent-A-Center, West, Inc. v. Jackson, 561 US 63 (2010) A party wanting to challenge the delegation provision must attack it specifically; a generalized argument that the whole contract is unconscionable goes to the arbitrator, not the court.
The language has to be “clear and unmistakable.” Vague or ambiguous wording about who decides arbitrability defaults the question back to the court. Delegation is a powerful tool but it cuts both ways: a party with a genuine enforceability argument may struggle to escape arbitration before litigating the merits.
Small Claims and Injunctive Relief Carve-Outs
Well-drafted consumer clauses commonly carve out small-dollar claims so either party can use small claims court. Arbitration often costs more than small claims court for low-value disputes, because the winning party still has to petition a separate court to convert the award into an enforceable judgment.9University of Florida Law Review. Unbundling Procedure: Carve-Outs From Arbitration Clauses The carve-out also reduces unconscionability risk by removing the worst optics.
Injunctive relief is a second common carve-out. Arbitrators lack the enforcement mechanisms courts have, such as contempt power, so parties frequently reserve the right to seek preliminary injunctions in court regardless of the arbitration clause.
Confidentiality
Arbitration is private in that hearings happen in conference rooms rather than open courtrooms, but private and confidential are different. Without an explicit confidentiality provision, either party can share filings, evidence, and the final award with anyone. If quiet matters, the clause needs to say what is covered: the existence of the proceeding, documents exchanged, hearing testimony, and the award itself.
Even strong language has limits. If a party asks a court to confirm or vacate the award, the filing becomes public record. Courts rarely seal these unless the material qualifies as a trade secret or similar. And a confidentiality agreement between two parties will not stop a non-party from subpoenaing the award in separate litigation. When real secrecy is the point, a standalone confidentiality agreement often protects more than a few sentences inside the arbitration clause.
Making the Clause Stick
Assent and Consideration
An arbitration clause needs mutual assent and consideration like any other contract term. Assent typically comes through a signature or a clear “I agree” click. Browsewrap arrangements, where merely using a website supposedly constitutes acceptance, get far less deference because there is no evidence the user ever saw the terms.
Consideration trips up employers who add arbitration clauses after the employment relationship has already begun. Whether continued employment alone counts as adequate consideration varies by jurisdiction. The safer route is to tie the new clause to something new: a raise, a signing bonus, or added benefits. In business-to-business contracts, mutual promises to arbitrate generally supply consideration on both sides.
Electronic Signatures
The federal E-SIGN Act confirms that an electronic signature or record cannot be denied legal effect solely because it is electronic.10Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity A properly implemented clickwrap agreement satisfies the writing and signature requirements. For consumer contracts, E-SIGN requires the consumer to receive a clear statement of the right to obtain paper records, the right to withdraw electronic consent, and the hardware and software needed to access the records. Skipping those disclosures undermines the argument that consent was meaningful.
Conspicuousness
Courts examine how visible the arbitration language is. Burying it on page 47 of a 60-page document in shrunken font invites a finding that the signer never meaningfully agreed. Steps that strengthen enforceability: use a separate signature line or initials block next to the provision, bold or capitalize the text explaining that the signer is waiving the right to a jury trial, and put the clause near the signature page. None of this is technically required in every jurisdiction, but each measure reduces the chance of a successful challenge.
Unconscionability
A clause that meets every formation requirement can still be voided as unconscionable. Courts examine two dimensions, and most demand some showing of both.
Procedural unconscionability looks at how the agreement came together. The hallmark is a take-it-or-leave-it adhesion contract in which the weaker party had no real ability to negotiate. Hidden terms, confusing language, and high-pressure signing environments all cut against enforcement.11Cleveland State Law Review. Unconscionability Found: A Look at Pre-Dispute Mandatory Arbitration Agreements
Substantive unconscionability looks at whether the terms themselves are unreasonably lopsided. Provisions that routinely draw judicial pushback include requiring one party to arbitrate while the other keeps the right to sue, imposing costs that effectively block the weaker party from filing a claim, capping one party’s damages while leaving the other’s intact, and forcing a consumer to travel to a distant forum over a small dispute.11Cleveland State Law Review. Unconscionability Found: A Look at Pre-Dispute Mandatory Arbitration Agreements The balance between procedural and substantive unfairness is flexible; extreme one-sidedness in the terms can offset moderate procedural issues and vice versa. Where both appear in abundance, the clause almost certainly fails.
Severability
A severability provision lets a court strike a bad term and enforce the rest of the clause. If a fee-shifting term is abusive but the remainder is fair, the court removes the offending language and sends the parties to arbitration under what survives. Courts will not sever their way through an agreement full of problems, though. Multiple unconscionable terms suggest the drafter was stacking the deck, and the court is likelier to refuse enforcement altogether. Include severability as insurance, not as license to draft aggressively.
Claims You Cannot Force Into Arbitration
Even a well-drafted clause cannot compel arbitration of certain federal claims. The Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act, enacted in March 2022, gives anyone alleging sexual assault or sexual harassment the unilateral right to reject a pre-dispute arbitration agreement and take the case to court.12Office of the Law Revision Counsel. 9 USC 402 – No Validity or Enforceability The statute defines a “sexual assault dispute” as one involving nonconsensual sexual acts or contact, and a “sexual harassment dispute” as one alleging conduct that constitutes sexual harassment under applicable federal, tribal, or state law.13Office of the Law Revision Counsel. 9 USC 401 – Definitions The claimant chooses the forum; the other party’s preference does not matter.
Two details matter at the drafting stage. Whether this law applies to a given dispute is decided by a court, not an arbitrator, even when the contract contains a delegation clause.12Office of the Law Revision Counsel. 9 USC 402 – No Validity or Enforceability And the law applies only to disputes arising on or after enactment; it does not reach claims that accrued earlier.
After the Award
An arbitration award is not self-executing. The winning party must ask a court to confirm the award, converting it into an enforceable judgment. The FAA gives one year from issuance to file the motion.14Office of the Law Revision Counsel. 9 USC 9 – Award of Arbitrators; Confirmation; Jurisdiction; Procedure The clause can name a court with jurisdiction; if it does not, the application goes to the federal district court where the award was made.
The losing party’s options are narrow. Under Section 10 of the FAA, a court can vacate an award only in four situations:
- The award was procured by corruption, fraud, or undue means.
- There was evident partiality or corruption in the arbitrator.
- The arbitrator refused to hear pertinent evidence, denied a reasonable postponement, or otherwise prejudiced a party’s rights.
- The arbitrator exceeded their powers or failed to make a definite award on the matters submitted.
The deadline to file a motion to vacate is three months after the award is delivered, not three months after the losing party decides to challenge it.15Office of the Law Revision Counsel. 9 USC 12 – Notice of Motions to Vacate or Modify; Service; Stay of Proceedings Miss it and the award stands regardless of how strong the challenge might have been. Draft with that clock in mind, and make sure the parties understand it before signing. Binding arbitration means what it says: once the award is issued, the road back to court is short, narrow, and governed by an unforgiving deadline.
