Served With a Lawsuit in New York: What to Do First
The first days after service are mostly about protecting the facts and the calendar, and nearly all of it is within your control.

Being served with a lawsuit is a jolt. Someone hands you papers, or they arrive by mail or at your door, and suddenly you are a defendant in a case you may not have expected. The first days matter, and most of what helps is simple and fully within your control.
Do not ignore the papers
The worst response to a lawsuit is silence. A court case does not go away because you set the papers aside. If a defendant fails to respond in time, the other side can ask the court to rule in its favor without ever hearing from you.
Read everything you received, start to finish. Then put it all in one folder: the summons, the complaint if it is attached, every cover page, the envelope, and anything else that came with it. Do not throw away the envelope or the packaging, because they can show how and when the papers arrived.
The deadlines in a New York case are printed in the court rules, and they start running from specific events, such as when and how service was completed. That is why the timing details below matter so much.
Write down how and when you were served
While your memory is fresh, write down exactly what happened. Who handed you the papers, or where were they left? What day and time was it? Did the person say anything? Were you at home, at work, or somewhere else?
There are rules about how a person or a business must be served, and the way it happened can affect the timeline. You do not need to decide whether service was proper. You only need to record it accurately so a lawyer can look at it with you.
- The date and approximate time you received the papers
- Where you were, or where the papers were left
- Who delivered them and what they looked like
- Whether a second set also came in the mail, and the postmark if so
Find the court and the index number
Look at the top of the first page. You should see the name of a court, the names of the parties on either side of a line, and a case number. In New York State courts that number is called an index number. In federal court it is usually called a docket number or a case number.
These identifiers tell a lawyer where the case lives and how to look it up. Write them down on their own, and take a photo of the first page with your phone so you always have a copy. The names in the caption also tell you who is suing you, which is sometimes not who you expected.
Notice, too, whether the papers name you personally, your business, or both. People who run small companies are often surprised to see their own name on the papers next to the company's.
What not to do
Fear and frustration push people toward moves that make a case harder. A few habits are worth avoiding from the first hour.
- Do not ignore the papers or assume the problem will sort itself out
- Do not call or message the other side to argue your position, because anything you say can be used later
- Do not delete emails, texts, photos, or files, even the ones you wish did not exist
- Do not post about the case on social media
- Do not sign anything the other side sends you without having someone review it
If the other side or their lawyer contacts you, you can politely say that you will respond through proper channels. Then write down what was said and when.
Gather your documents
Start collecting anything connected to the dispute: contracts, emails, text messages, invoices, receipts, photographs, payment records, and notes you made at the time. Keep the originals untouched and work from copies. Do not reorganize or edit anything, because a file that looks altered can raise questions you do not want.
It also helps to write a short timeline in plain words: what happened, in what order, with rough dates. A clear timeline saves time in a first conversation with a lawyer and helps you spot the documents you are missing.
Why to call a litigator early
A lawsuit moves on a calendar. Your answer, and any motion your side may want to make, run on deadlines printed in the court rules, and a missed deadline can cost you options that are hard to get back. The earlier you speak with a litigator, the more room there is to read the complaint carefully, understand what it actually claims, and decide how to respond.
A lawyer can also tell you what the papers mean in practical terms. Some complaints are broad and some are narrow. Some name the wrong party. Some ask for more than the facts support. You cannot judge that from a first read when you are upset.
