1. Which Contract Clauses Affect Whether You Can File Suit?
An unpaid invoice does not necessarily permit an immediate lawsuit. The agreement may first require notice, an opportunity to cure, or negotiations. Review the executed contract, amendments, and incorporated terms to determine which steps apply.
Notice, Cure, and Negotiation Requirements
Default clauses may specify the recipient, delivery method, and effective date of notice. An email to an account manager may not satisfy a requirement for delivery to a designated address. That distinction matters when compliant notice starts the cure period.
In breach of contract litigation, mandatory negotiations or mediation may also affect when suit can proceed. Their effect depends on the language and applicable law. Settlement discussions alone do not suspend limitation periods, so filing deadlines need separate review.
Arbitration, Forum Selection, and Governing Law
Governing law identifies the substantive law selected by the parties. Forum selection identifies an agreed court or location. Arbitration clauses may require a private tribunal to decide covered disputes.
The Federal Arbitration Act may apply to agreements involving interstate commerce. New York’s CPLR Article 75 also governs arbitration-related court proceedings. Review the scope and exceptions of a commercial arbitration clause before filing. Permission to request temporary court relief does not necessarily allow litigation of the underlying claim.
2. Which Court Can Hear the Dispute?
Court selection requires a basis for subject-matter jurisdiction, personal jurisdiction over the defendant, and proper venue. A Manhattan office or New York governing-law clause does not establish each requirement. State and federal courts apply different jurisdictional and procedural rules.
New York County Supreme Court
New York Supreme Court is a state trial court with broad civil jurisdiction. Personal jurisdiction concerns authority over the defendant; venue concerns the county where the action should proceed.
CPLR §503 generally permits venue based on a party’s residence or where a substantial part of the relevant events occurred, subject to other rules. Written venue agreements also matter under CPLR §501. Selecting New York law differs from selecting courts in New York County.
Southern District of New York
Federal jurisdiction commonly rests on a federal question or diversity of citizenship. Ordinary diversity jurisdiction generally requires complete diversity between opposing parties and more than $75,000 in controversy, excluding interest and costs.
A corporation’s citizenship generally follows incorporation and its principal place of business. An LLC’s generally follows its members, including through additional ownership layers. A contract cannot create missing federal subject-matter jurisdiction.
State cases follow the CPLR and applicable court rules. SDNY cases follow federal procedural rules, local rules, and the assigned judge’s practices. Federal filing does not necessarily change the substantive law governing the contract.
3. Does the Case Qualify for the Commercial Division?
The Commercial Division is a specialized division within New York Supreme Court. Assignment depends on the claims, value, exclusions, and procedural requirements. Its monetary threshold determines division eligibility, rather than the minimum amount needed to sue in Supreme Court.
Monetary Threshold and Eligible Claims
New York County generally applies a $500,000 threshold under 22 NYCRR §202.70, excluding punitive damages, interest, costs, disbursements, and counsel fees. Specified contract disputes, business torts, and internal business matters may qualify.
Some cases remain excluded despite their value, including professional fee collection and commercial real estate disputes involving rent payment only. A complex commercial litigation assessment should therefore address both claim type and amount.
Exceptions and Assignment Timing
Requesting an injunction or declaratory judgment does not automatically bypass the threshold. The rule considers the value of the intended benefit, protected right, or avoided injury, whichever is greatest. Specified exceptions include shareholder derivative actions, commercial class actions, and business dissolution proceedings.
A party generally must request assignment within 90 days after service of the complaint through a Request for Judicial Intervention and Commercial Division Addendum. This deadline differs from commencement, service, and limitation deadlines.
4. What Should the Business Prepare before Filing?
The filing review should connect the agreement, relevant events, requested relief, and proposed forum. Missing notices, incorrect party names, or unsupported losses may change whether the next step is litigation, arbitration, or completion of a contractual requirement.
Documents and Claim Amount
Prepare the following records:
- Executed contracts, amendments, guarantees, and incorporated terms.
- Default notices, delivery confirmations, and responses.
- Invoices, payment records, and evidence of performance.
- Loss calculations supported by identifiable documents.
Preserve relevant electronic records when litigation is reasonably anticipated. Distinguish supported losses from amounts affected by contractual caps, exclusions, credits, or defenses, and assess potential counterclaims separately.
Electronic Filing and Service
New York County Supreme Court generally requires NYSCEF filing, subject to exemptions. SDNY uses CM/ECF. Each court also imposes document requirements and individual judicial practices.
Filing does not complete initial service. CPLR §304 governs commencement of a state action, generally by filing a summons and complaint or summons with notice. CPLR §306-b generally requires service within 120 days, subject to exceptions and possible extensions. Before filing, confirm the proper entities, jurisdiction, venue, service method, and applicable deadlines.
