How to File a Lawsuit in New York and Choose the Right Court

Practice Area:Corporate
Jurisdiction:New York

How to file a lawsuit in New York depends on court jurisdiction, claim value, filing requirements, and applicable deadlines.


Before filing, plaintiffs must determine whether their case belongs in state court, federal court, or small claims court. Claim type, damages, and legal deadlines affect that choice. Knowing where and how to file can help prevent costly procedural mistakes.



1. Choose the Court That Can Hear Your Claim


A court must have authority over the dispute and the defendant. Start with the type of claim, the parties, and the remedy sought. A larger claim does not automatically belong in federal court.


Check Federal Jurisdiction

  • Federal-question jurisdiction generally covers claims arising under federal law, under 28 U.S.C. § 1331.
  • Diversity generally requires complete diversity and more than $75,000 at stake, excluding interest and costs.
  • Federal patent and copyright claims generally belong in federal court; federal trademark claims are not categorically exclusive.

Bankruptcy matters follow separate rules under 28 U.S.C. § 1334. Diversity alone does not prevent a state-court filing.

Choose the Appropriate State Trial Court

  • NYC Civil Court generally hears money claims up to $50,000.
  • Supreme Court is a trial court with broad civil jurisdiction.
  • Check venue, the defendant's connections to the forum, and any specialized rules.

Limits differ outside the city. Related civil litigation questions may affect where a claim belongs.


2. Determine Whether Small Claims Court Fits


For smaller money disputes, small claims may offer a simpler filing process. Eligibility depends on the court, the amount, and who brings the claim. It generally does not provide orders requiring someone to perform an act.


Compare Small-Claims Monetary Limits

CourtClaim Limit
NYC Civil Court$10,000
City Court or applicable District Court$5,000
Town or Village Justice Court$3,000

NYC Civil Court

  • Claim Limit$10,000

City Court or applicable District Court

  • Claim Limit$5,000

Town or Village Justice Court

  • Claim Limit$3,000

You cannot divide one larger claim into smaller cases simply to bypass the monetary limit.

File the Small-Claims Form

  • Use the defendant's correct legal name and a usable address.
  • State the amount owed and briefly explain why.
  • Submit the clerk's form and fee, then follow hearing instructions.

The court generally sends notice; unsuccessful delivery may require further action. Ordinary civil service rules differ.


3. Identify the Proper Plaintiff and Presuit Requirements


Filing under the wrong name can delay a valid claim. Decide who suffered the legal loss and whether a demand letter is useful or required. Settlement talks generally do not stop the filing clock.


Distinguish Individual and Business Claims

  • Individuals can generally sue for their own injuries or contractual losses.
  • Companies bring claims belonging to the entity, not automatically to its owners.
  • Corporations generally need an attorney under CPLR § 321 in ordinary civil actions.

Eligible businesses may instead file commercial small claims and use authorized representatives under special rules.

Assess Notices, Settlement, and Fees

  • Check contractual notices, administrative requirements, and claims against public entities.
  • Commercial small-claims consumer transactions require a presuit demand letter under specific rules.
  • Compare likely recovery with filing costs and permitted hourly or contingency fees.

A breach of contract lawsuit may require both a deadline review and a practical settlement assessment.


4. Prepare the Pleading, File, and Serve the Defendant

The court needs facts supporting a recognized legal claim and the requested relief. State and federal filing procedures differ. Drafting carefully also helps identify evidence to preserve.


Match the Allegations to the Claim

  • Contract claims generally identify the agreement, breach, and resulting loss.
  • Negligence claims address duty, breach, causation, and injury.
  • Fraud claims face particularity rules under CPLR § 3016(b) or federal Rule 9(b).

Not every tort carries heightened pleading requirements. Damages also need a factual basis.

Complete Commencement and Service

  • Under CPLR § 304, file a summons and complaint or summons with notice to start an ordinary state action.
  • Obtain an index number and comply with applicable electronic-filing rules.
  • Serve the papers properly and retain proof of service.

CPLR § 306-b generally allows 120 days, but certain short-limit claims follow a different rule. Federal Rules 3 and 4 govern federal commencement and service.


5. Check Filing Deadlines and Trial Choices


A strong claim can fail if filed too late. Calculate the limitation period before extending negotiations. Service deadlines and jury-demand rules need separate attention.


Calculate the Deadline for the Claim

  • CPLR § 213 generally provides six years for many contract claims.
  • CPLR § 214 generally provides three years for ordinary personal-injury claims.
  • Check shorter periods, notice-of-claim requirements, and any applicable tolling.

Special claims can follow different rules. Examine statute of limitations questions before relying on an extension.

Decide How to Request a Trial

  • Determine whether the disputed issues qualify for a jury trial.
  • In state court, CPLR § 4102 generally connects jury demands to the note of issue.
  • In federal court, Rule 38 generally allows 14 days after service of the last relevant pleading.

Jury availability and procedural deadlines vary. Trial preparation costs may also influence the choice.


6. Frequently Asked Questions


Can I sue an out-of-state defendant in New York?

Possibly. The court needs personal jurisdiction over that defendant, and venue must also be appropriate.


What if I cannot find the defendant's address?

Investigate available service methods. A court may permit alternative service when legal requirements are satisfied.


What if the defendant does not pay a small-claims judgment?

Winning does not guarantee collection. You may need lawful enforcement measures based on the defendant's assets.



7. Review Your Filing Plan before Going to Court


Choosing the wrong forum or missing a service deadline can complicate a claim before its merits are heard. Confirm the proper plaintiff, court, filing method, and timing.
