Which court you are in
The New York court system can be confusing. The Supreme Court is the main trial-level court for larger civil disputes, despite its name, and the Court of Appeals is the state's highest court. In New York City, the Civil Court handles claims below a set amount, and its small claims part handles simpler disputes with less formality. Outside the city, smaller matters often go to county, city, district, or town and village courts, depending on the location. Federal court is available for cases involving federal law or, in many situations, parties from different states. The court your case is in affects the rules, the timing, and the cost.
If you have been served
A summons comes with a deadline to respond, and it is short. If you do not answer in time, the other side can ask for a default judgment, which may lead to a restraint on your bank account or a deduction from your wages. Getting a default lifted later usually requires showing both a reasonable excuse and a potential defense. Note the date and the way the papers were delivered, since that affects the deadline. Do not ignore the papers even if you believe the claim is wrong or that you were never properly served.
If you are thinking of suing
Before filing, consider whether the other side can actually pay a judgment, whether a contract requires arbitration or a specific court, and whether a demand letter could resolve the matter. Time limits for filing vary by claim and by state. Gather the documents that show what happened and what it cost you. Together we look at the claim or defense, which court fits, the likely costs, and the realistic ways to resolve it, including negotiation before or after filing.
