There is an arbitration clause. Who decides whether it applies?

A court decides whether an arbitration clause exists and whether it reaches your dispute, unless the contract clearly and unmistakably hands that question to the arbitrator. In New York, CPLR 7503 supplies the procedure. Service of a notice of intention to arbitrate starts a twenty-day clock. Miss it and you are precluded, with one narrow exception.

Who decides whether an arbitration clause applies — the judge or the arbitrator?

Under New York law, a court decides three threshold questions: whether an arbitration agreement was made, whether the dispute falls within its scope, and whether any condition precedent to reaching the arbitration forum was satisfied. An arbitrator decides the merits. That default flips only where the contract clearly and unmistakably delegates arbitrability to the arbitrator.

Case: Matter of County of Rockland (Primiano Constr. Co.), 51 NY2d 1, 7-8 (1980).

Case: First Options of Chicago, Inc. v. Kaplan, 514 U.S. 938, 944 (1995).

The court is the gatekeeper. The arbitrator is the decider.

Here is the sorting, as New York practice. Two rows change when the FAA supplies the rule.

How do you move to compel arbitration in New York under CPLR 7503?

CPLR 7503(a) lets a party aggrieved by another’s failure to arbitrate apply for an order compelling arbitration. If a lawsuit is already pending and that court can hear the motion, you make the application by motion in that action. If no action is pending, you commence a special proceeding instead.

Law: CPLR 7503(a); CPLR 7502(a).

The standard inside the statute is unusual. The court must direct the parties to arbitrate where there is no substantial question whether a valid agreement was made or complied with, and the claim is not barred by the limitation rule in CPLR 7502(b). Where such a question is raised, the statute says it shall be tried forthwith in that court.

A genuine factual fight over formation is not resolved on papers by default. It gets tried. Your affidavits either eliminate the question or create one.

If the application is granted, the order operates to stay the pending or subsequent action, or so much of it as is referable to arbitration.

What does the twenty-day deadline in CPLR 7503(c) actually do?

CPLR 7503(c) lets one party serve a demand for arbitration or a notice of intention to arbitrate. The notice must specify the agreement, identify the serving party, and state that unless the party served applies to stay within twenty days, that party is precluded from objecting. Service follows summons rules, or registered or certified mail, return receipt requested.

Law: CPLR 7503(c).

Preclusion means what it sounds like. Twenty days after proper service of a conforming notice, you lose the right to object that a valid agreement was not complied with and to assert the CPLR limitation bar in court. The objections do not weaken. They disappear. One category survives.

Case: Matter of Steck (State Farm Ins. Co.), 89 NY2d 1082, 1084 (1996).

Two details matter.

• The clock runs from service, and service must be made in the manner the statute prescribes. A demand emailed to your general counsel is not automatically service.
• The notice must comply with CPLR 7503(c) on its face. A notice that omits the required preclusion warning does not start an enforceable twenty-day period.

Case: Matter of Ameriprise Ins. Co. v Sandy, 158 AD3d 623, 624 (2d Dept 2018).

One more provision matters. Any term in an arbitration agreement or its rules purporting to waive the right to apply for a stay is null and void under the statute. A promise not to go to court to stop an arbitration does not bind you in a New York court.

This clock is New York procedure. The FAA has no equivalent preclusion rule.

The twenty-day clock is not a formality. It is a forfeiture rule with a calendar attached.

What if you never agreed to arbitrate anything at all?

New York recognizes a narrow escape from CPLR 7503(c) preclusion where the objection is that the parties never made an arbitration agreement in the first place. That is different from saying an agreement exists but is invalid, or that its conditions were not met. The first survives a late application. The second does not.

Case: Matter of Matarasso (Continental Cas. Co.), 56 NY2d 264, 266-267 (1982).

Case: Matter of Commerce & Indus. Ins. Co. v Nester, 90 NY2d 255, 262 (1997).

One fact pattern. A vendor serves a demand citing a master agreement your company negotiated but never executed. You do nothing for six weeks. You can still be heard, because your position is that no agreement to arbitrate was ever made. Being heard is not winning: an unsigned document can still bind you if the course of dealing shows both sides meant to be bound.

Change one fact. You signed, and your objection is that the vendor skipped the mandatory pre-arbitration mediation step. That is non-compliance, not non-existence. Sleep on it for six weeks and the objection is gone, unless the notice was defective or improperly served.

CPLR 7503(b) has its own prerequisites. The applicant must not have participated in the arbitration and must not have made or been served with an application to compel. Appear at a preliminary conference and you may have spent the right you were about to assert.

Law: CPLR 7503(b).

Who decides whether a condition precedent to arbitration was satisfied?

In New York, a court decides whether a condition precedent to reaching the arbitration forum was satisfied. Conditions precedent to arbitration are the steps the contract requires before anyone may file: notice, a cure period, a mediation session, a contractual filing deadline. Whether a party performed its substantive obligations is a merits question for the arbitrator.

Case: Matter of County of Rockland (Primiano Constr. Co.), 51 NY2d 1, 7-8 (1980).

New York courts apply that rule to contractual time limits, treating a bargained-for deadline for demanding arbitration as a condition precedent for the court to police.

Case: Matter of Enlarged City School Dist. of Troy (Troy Teachers Assn.), 69 NY2d 905, 907 (1987).

Draw the line this way. “Did they send the required 30-day default notice before demanding arbitration?” is a gatekeeping question. “Was the default real?” is a merits question.

That allocation is state law. Where the FAA supplies the rule, procedural gateway questions — notice periods, contractual deadlines, limitations defenses — are presumptively for the arbitrator.

Case: Howsam v. Dean Witter Reynolds, Inc., 537 U.S. 79, 84-85 (2002).

Settle the governing law first. The same facts can be a judge’s question under article 75 and an arbitrator’s under the FAA.

What is a delegation clause, and can it take the question away from the court?

A delegation clause is contract language assigning questions of arbitrability — scope, validity, enforceability — to the arbitrator rather than to a judge. Where a contract clearly and unmistakably delegates that question, the court must send it to arbitration. It may not keep it on the theory that the arbitration demand looks weak.

Case: Henry Schein, Inc. v. Archer & White Sales, Inc., 586 U.S. 63 (2019).

The Supreme Court rejected the wholly groundless exception, under which lower courts kept arbitrability whenever the demand looked meritless. That shortcut is gone.

Two limits survive it. A court must still satisfy itself that a valid arbitration agreement exists before referring anything, including arbitrability, to an arbitrator. And silence is not delegation: the evidence of intent must be clear and unmistakable.

Case: First Options of Chicago, Inc. v. Kaplan, 514 U.S. 938, 944 (1995).

One statutory override matters. For a sexual assault or sexual harassment dispute under the federal Ending Forced Arbitration Act, a court decides whether that statute applies, even if the contract delegates arbitrability.

Law: 9 U.S.C. 401-402.

The practical consequence is a reading assignment. Read the dispute resolution article word by word before you oppose a motion to compel. Look for language delegating questions of interpretation, applicability, or enforceability. Look for incorporation of an administering body’s rules, which many courts treat as clear and unmistakable delegation, though results vary. If a delegation exists and is not itself successfully challenged, your scope argument belongs to the arbitrator.

Does the Federal Arbitration Act change the answer when the contract crosses state lines?

The FAA reaches written arbitration provisions in contracts involving interstate commerce, which describes most agreements between a New York business and an out-of-state counterparty. Its substantive rules on validity, delegation, and waiver bind state courts too. Its procedural sections do not: a New York court still runs the case under CPLR article 75.

Law: 9 U.S.C. 2.

Two recent decisions matter.

First, when a federal court finds a dispute arbitrable and a party has requested a stay, section 3 requires a stay; the court cannot dismiss instead. That matters, because a dismissal creates an appealable final judgment and a stay does not.

Case: Smith v. Spizzirri, 601 U.S. 472 (2024).

Second, courts applying the FAA may not invent arbitration-specific waiver rules. The Supreme Court rejected the requirement that a party opposing arbitration show prejudice. Waiver is analyzed like waiver of any contract right, by the conduct of the party that held it.

Case: Morgan v. Sundance, Inc., 596 U.S. 411 (2022).

A caution about sequencing. Do not assume a federal overlay rescues a missed twenty-day deadline in New York. Move within twenty days, then argue preemption.

Can you lose the right to arbitrate by litigating first?

Yes. A party that litigates a dispute in court instead of demanding arbitration can waive the right to arbitrate that dispute. New York looks at what the party actually did: whether it answered without asserting arbitration, took discovery, filed its own affirmative claims, and how long it stayed in court before changing its mind.

Case: Sherrill v Grayco Builders, Inc., 64 NY2d 261, 272-273 (1985).

The Court of Appeals found waiver where a party spent roughly three years in litigation without mentioning arbitration, answered with a general denial, brought its own action, took a deposition, and pursued document discovery. Not every foray into the courthouse effects a waiver.

Which side of the caption you sit on matters. A plaintiff who brings an arbitrable claim in court is generally treated as having waived. A defendant is not, and is measured step by step.

Case: De Sapio v Kohlmeyer, 35 NY2d 402, 405 (1974).

The other direction is real. New York policy favors arbitration, and there is no waiver where urgent need justifies resort to the courts. Read that limit narrowly: the Court of Appeals restated it while noting the record before it showed no such exigency.

Case: Stark v Molod Spitz DeSantis & Stark, P.C., 9 NY3d 59, 66-68 (2007).

Arbitration rights are not preserved by intention. They are preserved by conduct, on the record, early.

What should you do in the first twenty days?

Your first twenty days decide most of what follows, because CPLR 7503(c) converts silence into forfeiture and because early litigation conduct can waive arbitration outright. Work the deadline first, the merits second. Six concrete steps, in order, before you file anything responsive to a complaint or a demand for arbitration.

• Date the service. Record the exact day and manner of service of the notice, demand, or summons and complaint. Calendar day twenty and treat it as immovable.
• Pull the operative document. Not a form, not a term sheet. The signed instrument containing the arbitration provision, with every amendment and incorporated document.
• Read the dispute resolution article for a delegation clause. If arbitrability is delegated, your argument has a different audience.
• Identify every condition precedent and settle the governing law. Notice periods, cure periods, mediation steps, deadlines — and whether the FAA sends those questions to the arbitrator.
• Classify your objection honestly. “No agreement was ever made” behaves differently from “the agreement was not complied with.” Only the first reliably survives a late application.
• Stop generating litigation conduct. Do not serve discovery, file a counterclaim, or answer on the merits before deciding whether you are asserting arbitration. Every step in court is evidence of intent to litigate.

Then choose the posture. Compel under CPLR 7503(a), by motion if an action is pending and by special proceeding if none is. Or move to stay under CPLR 7503(b) within the twenty days. Doing neither is itself a decision, and it is the one the statute punishes.
