When Can You File a Motion to Compel Arbitration?

You can file a motion to compel arbitration as soon as three things are true: a valid written arbitration agreement covers your dispute, the other party has refused to arbitrate, and you haven’t forfeited the right by litigating the case in court for too long. The motion asks a judge to enforce the agreement and route the dispute to a private arbitrator. Federal law tilts strongly toward granting these motions, but each of those three conditions has to hold up under scrutiny before a judge will sign the order.

The Three Conditions for Filing

Under the Federal Arbitration Act, a written arbitration clause in a contract involving interstate commerce is “valid, irrevocable, and enforceable.”¹ That standard reaches almost every modern employment contract, consumer agreement, and commercial deal, because very few transactions are purely local.

The second condition is a refusal to arbitrate. The FAA lets a party petition the federal district court that would otherwise hear the case for an order directing arbitration to go forward.² If the other side has already sued you, you file the motion in the same court where the lawsuit is pending.

The third is timing. A party who spends months acting like a litigant, taking discovery, filing counterclaims, and never mentioning arbitration, can lose the right to compel it. More on that below.

What a Valid Arbitration Agreement Looks Like

The agreement must satisfy basic contract law. Both parties need to have actually agreed to the terms, and each side must have given something of value. A clause buried in fine print that nobody signed or clicked through can be challenged on the ground that there was no genuine acceptance. Courts ask whether a reasonable person would have understood they were agreeing to arbitrate.

The clause doesn’t have to be a standalone document. Arbitration provisions appear inside employment contracts, consumer terms of service, account agreements, and purchase orders. What matters is that the arbitration language itself is written and that the parties assented to it.

Is Your Dispute Actually Covered?

Having an arbitration clause is only the start. The specific dispute also has to fall within what the clause covers, and the drafting matters.

A broad clause typically reaches “any and all disputes arising out of or relating to” the agreement. Courts read that language generously, sweeping in contract claims and related theories like negligence or fraud whenever they have a meaningful connection to the contract. The practical result is that nearly any dispute between the parties ends up in arbitration, partly because courts dislike splitting related claims between a courtroom and an arbitration panel and risking contradictory results.

A narrow clause limits arbitration to specific categories, such as disputes about payment terms or contract interpretation. If your clause is narrow, a court will stick to its text. A personal injury claim arising from the same business relationship might fall entirely outside it.

Defenses That Can Defeat the Motion

Even a clearly written arbitration clause can be beaten by the same defenses that void any contract. The FAA’s saving clause preserves challenges based on fraud, duress, or unconscionability, but only when those defenses apply to contracts generally rather than singling out arbitration agreements for special treatment.³ A state law that voids arbitration clauses categorically is preempted. A state law that voids all one-sided contracts, arbitration agreements included, survives.

Unconscionability is the defense courts see most often, and it has two sides. Procedural unconscionability looks at how the agreement was formed: was it a take-it-or-leave-it contract with no real ability to negotiate? Substantive unconscionability looks at the terms themselves: does the clause force one party to arbitrate while letting the other side go to court? When both are present, a court may refuse to enforce the clause.

Fraud claims are trickier. If the argument is that the entire contract was induced by fraud, that question goes to the arbitrator, not the judge. A federal court reviewing a motion to compel “may consider only the issues relating to the making and performance of the agreement to arbitrate.”⁴ Only fraud aimed directly at the arbitration clause itself will persuade a judge to deny the motion.

The Sexual Assault and Harassment Exception

Federal law carves out one significant exception. Under the Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act, anyone alleging sexual assault or harassment can choose to pursue the claim in court regardless of any arbitration agreement they previously signed.⁵ A court, not an arbitrator, decides whether the exception applies, even when the agreement contains a delegation clause. A motion to compel arbitration filed against one of these claims will be denied if the claimant elects to stay in court.

Delegation Clauses: Who Decides What

Some arbitration agreements hand the threshold questions themselves to the arbitrator. A delegation clause gives the arbitrator authority over gateway issues like whether the agreement is valid or whether a particular claim falls within its scope. The Supreme Court has held that these clauses are enforceable when there is clear and unmistakable evidence the parties intended to delegate that question.⁶

When a delegation clause is present and unchallenged, the judge’s role shrinks. The court doesn’t decide whether the dispute belongs in arbitration. It enforces the delegation clause and sends that question to the arbitrator. If you want a court to resolve arbitrability, your challenge has to target the delegation clause specifically. A challenge aimed at the broader arbitration agreement goes to the arbitrator.

Don’t Wait Too Long

Filing early is far safer than filing late. A party that sits on its right to arbitrate while digging into the court process can lose that right entirely.

Conduct that courts treat as inconsistent with an intent to arbitrate includes filing counterclaims without mentioning the arbitration agreement, participating in extensive discovery, and significant delay in raising arbitration after the lawsuit begins. The longer a party behaves like a litigant, the weaker its eventual motion becomes.

Until 2022, most federal courts required the party opposing arbitration to show it had been harmed by the delay. The Supreme Court eliminated that requirement unanimously, holding that the FAA does not authorize arbitration-specific procedural rules like a prejudice requirement. The focus now is entirely on whether the party seeking arbitration behaved inconsistently with that right. If the conduct looks like someone who chose litigation, a court can find waiver regardless of whether the delay actually hurt the other side.

A Note on Class Action Waivers

If you’re on the defense side of a class action, the arbitration clause may also contain a class action waiver. The Supreme Court has confirmed that the FAA requires enforcement of these provisions, even when a federal statute like the National Labor Relations Act might otherwise protect collective legal action.⁷ A defendant facing a class action can file a motion to compel individual arbitration for each class member, which effectively dismantles the class. The EFAA carve-out voids pre-dispute joint-action waivers alongside arbitration agreements in sexual assault and harassment cases, but outside that category class waivers are broadly enforceable.⁵

How to File

You file the written motion in the U.S. district court that would otherwise have jurisdiction over the dispute, or in the court where the lawsuit against you is pending. The motion identifies the arbitration agreement and explains why the dispute falls within its scope.

The FAA requires at least five days’ written notice to the opposing party, served under the Federal Rules of Civil Procedure.² In practice, most courts expect the motion to include a copy of the arbitration agreement and a supporting declaration from someone familiar with the facts. Those documentary requirements come from local court rules rather than the FAA itself. The opposing party files a written response, and the court schedules a hearing.

If the existence of the agreement is genuinely in dispute, the FAA provides for a summary trial on that question, and the party alleged to be in default can even demand a jury trial on whether a written arbitration agreement was actually made.² This almost never happens, because most cases involve signed written agreements, but the right exists for genuine formation disputes.

What Happens After the Court Rules

If the court grants the motion and a party requests a stay, the court must pause the lawsuit rather than dismiss it. The Supreme Court settled this in 2024, holding that Section 3 of the FAA “compels the court to issue a stay” when a lawsuit involves an arbitrable dispute and a party asks for one.⁸ A stayed case stays open, which preserves the court’s ability to enforce the eventual arbitration award.⁹

If the court denies the motion, the losing party can take an immediate interlocutory appeal without waiting for the case to end.¹⁰ The FAA creates this asymmetry on purpose: forcing a party to litigate through a full trial before reviewing the arbitration ruling would effectively destroy the right. The flip side is that a party ordered into arbitration generally cannot take an immediate appeal and must complete the arbitration first.
