Personal service under the CPLR in New York means physically delivering the summons and complaint to the defendant in one of the ways CPLR 308 allows: handing the papers directly to the person, leaving them with someone of suitable age and discretion and mailing a copy, affixing them to the door and mailing a copy, or mailing them with an acknowledgment form the defendant signs and returns. Each method has its own conditions, deadlines, and proof requirements, and getting any of them wrong can cost the court its jurisdiction over the defendant and sink the case.
Who Is Allowed to Serve the Papers
You cannot serve your own lawsuit. Under CPLR 2103, the person who serves process must be at least 18 years old and cannot be a party to the action.1New York State Senate. New York Civil Practice Law and Rules Law R2103 – Service of Papers A friend, a relative who is not part of the case, or a professional process server all qualify.
In New York City there is an added layer. Anyone who serves process five or more times in a calendar year must be licensed by the Department of Consumer and Worker Protection.2NYC Department of Consumer and Worker Protection. Process Server Individual License Application Checklist Outside the city, no license is required, but the age and non-party rules still apply.
The Four Ways to Serve an Individual
CPLR 308 lists the methods for serving a natural person, and courts expect you to try the more direct ones before the less direct.3New York State Senate. New York Civil Practice Law and Rules Law 308 – Personal Service Upon a Natural Person
In-Hand Delivery
The cleanest method is handing the summons and complaint directly to the defendant anywhere within New York. No follow-up mailing is required, and there is almost no room for the defendant to argue they never received the papers. If you can do this, do it.
Substituted Service: Deliver and Mail
When the defendant cannot be reached in person, you can leave the papers with someone of suitable age and discretion at the defendant’s home, workplace, or usual residence, and then mail a copy to the defendant’s last known address. The delivery and the mailing must both happen within 20 days of each other.3New York State Senate. New York Civil Practice Law and Rules Law 308 – Personal Service Upon a Natural Person The statute does not set a specific age for “suitable age and discretion.” Courts look at whether the person appeared capable of understanding what the papers were and likely to pass them along.
Nail and Mail
If diligent efforts at both in-hand and substituted service fail, you may affix the papers to the door of the defendant’s home or workplace and mail a copy, with both steps completed within 20 days.3New York State Senate. New York Civil Practice Law and Rules Law 308 – Personal Service Upon a Natural Person This is where a lot of cases fall apart. Courts scrutinize the earlier attempts. A single Tuesday-afternoon visit does not qualify as diligence. You need multiple attempts at different times and on different days, including outside normal work hours, before nail and mail becomes appropriate.
Mail With Acknowledgment
CPLR 312-a offers a cheaper option. You mail the summons and complaint by first-class mail together with an acknowledgment form the defendant is asked to sign and return within 30 days.4New York State Senate. New York Civil Practice Law and Rules Law 312-A – Service of a Summons by Mail The defendant has to cooperate for this to work. If no signed acknowledgment comes back, you have to fall back to one of the CPLR 308 methods.
The Sunday Rule
Do not serve papers on a Sunday. New York General Business Law 11 makes Sunday service void, with narrow exceptions for criminal proceedings and situations where a specific statute authorizes it.5New York State Senate. New York General Business Law 11 – Serving Civil Process on Sunday This is easy to miss with nail-and-mail service in particular, so check the day of the week before you go.
Serving a Business
If the defendant is an entity rather than a person, the rules change and the choice of recipient matters.
Corporations
CPLR 311 lets you serve a domestic or foreign corporation by delivering the summons to an officer, director, managing or general agent, cashier, or assistant cashier, or to any agent the corporation has authorized to accept service.6New York State Senate. New York Civil Practice Law and Rules Law 311 – Personal Service Upon a Corporation or Governmental Subdivision Handing the papers to a receptionist or a random employee who holds none of these titles can be challenged as defective.
Business Corporation Law 306 gives you an alternative: deliver duplicate copies to the Secretary of State, who then forwards a copy to the corporation’s address on file. Service is legally complete when the Secretary of State is served, whether or not the corporation actually receives the forwarded copy.7New York State Senate. New York Business Corporation Law 306 – Service of Process This is often the easiest route when a company has closed its office or gone quiet.
Limited Liability Companies
LLCs work the same way through Limited Liability Company Law 303. You deliver duplicate copies to the Secretary of State with the statutory fee, and the Secretary mails a copy by certified mail to the LLC’s address on file. Service is complete on delivery to the Secretary of State.8New York State Senate. New York Limited Liability Company Law 303 – Service of Process on Limited Liability Companies New York also permits electronic submission through the Department of State’s online system if the LLC has an email address on file.
Partnerships and Sole Proprietors
A partnership can be served by delivering the summons to any one of the partners. You can also deliver to a managing or general agent at the partnership’s office within the state and then mail a copy to the partner you want to reach. Proof of that service must be filed with the court within 20 days, and service becomes complete 10 days after filing.9New York State Senate. New York Civil Practice Law and Rules Law 310 – Personal Service Upon a Partnership A sole proprietor is just an individual operating under a business name, so you serve them the same way you would any other individual under CPLR 308.
Serving Government Bodies and the State
Suing a municipality means delivering the summons to a specific official. For a city other than New York City, that is the mayor, comptroller, treasurer, counsel, or clerk. For a town, the supervisor or clerk. For a village, the mayor, clerk, or any trustee.6New York State Senate. New York Civil Practice Law and Rules Law 311 – Personal Service Upon a Corporation or Governmental Subdivision
To sue the State of New York itself, CPLR 307 requires delivering the papers to an assistant attorney general at any office of the Attorney General, or to the Attorney General personally.10New York State Senate. New York Civil Practice Law and Rules Law 307 – Personal Service Upon the State For a state officer sued in an official capacity or a state agency, you can deliver directly to the officer or the agency’s chief executive. Certified mail (return receipt requested) to the officer or agency head is an alternative, but it does not replace personal service on the State through the Attorney General.
Serving Minors and Incapacitated Persons
Defendants who cannot be expected to protect their own legal interests require extra steps under CPLR 309.11New York State Senate. New York Civil Practice Law and Rules Law 309 – Personal Service Upon an Infant, Incompetent or Conservatee
For a minor, you personally serve a parent, guardian, or person with legal custody. If the minor is married, service on the adult spouse works. If none of those people are in the state, you serve whoever the minor lives with or is employed by. If the minor is 14 or older, you must also serve the minor directly.
For a person who has been judicially declared incompetent, you serve the committee (the person appointed by the court to manage their affairs) and, unless the court says otherwise, the incompetent person as well. The same dual-service approach applies to conservatees: serve both the conservator and the conservatee, unless the court waives service on the conservatee.
Serving Someone Outside New York
You can serve a defendant outside the state, but only if the court has a basis to exercise jurisdiction over that person in the first place. CPLR 302, the long-arm statute, provides that basis in situations like non-residents doing business in New York, committing a harmful act inside the state, or owning real property here.12New York State Senate. New York Civil Practice Law and Rules Law 302 – Personal Jurisdiction by Acts of Non-Domiciliaries
Once jurisdiction is available, CPLR 313 governs the mechanics. Service outside the state must follow the same methods that would be used within New York, and it can be carried out by a New York resident authorized to serve within the state, any person authorized under the laws of the place where service is made, or a qualified attorney or equivalent in that jurisdiction.13New York State Senate. New York Civil Practice Law and Rules Law 313 – Service Without the State Giving Personal Jurisdiction Perfect service does not save a case that lacks a jurisdictional hook.
When the Standard Methods Won’t Work
If personal delivery, substituted service, and nail and mail have all proved impracticable, CPLR 308(5) lets you ask the court to authorize an alternative method.3New York State Senate. New York Civil Practice Law and Rules Law 308 – Personal Service Upon a Natural Person The motion is made without notice to the defendant, and you have to show that the standard methods genuinely failed despite diligent efforts.
Courts have approved creative approaches. In Baidoo v. Blood-Dzraku, the court permitted service through a private Facebook message after the plaintiff showed that traditional methods were impractical and the defendant regularly used his Facebook account.14NYCourts.gov. Baidoo v Blood-Dzraku (2015 NY Slip Op 25096) Judges have also authorized service by email and by newspaper publication in appropriate cases. The court weighs whether the chosen method is actually likely to reach the defendant, so a request for email service without evidence that the defendant uses that email address will usually fail.
The 120-Day Window Between Filing and Service
Filing the case and serving it are two different acts, and the gap between them is capped. CPLR 306-b requires you to serve the summons and complaint within 120 days after filing. If the applicable statute of limitations is four months or less, the deadline tightens to 15 days after the limitations period expires.15New York State Senate. New York Civil Practice Law and Rules Law 306-B – Service of the Summons and Complaint
Miss the window and the defendant can move to dismiss without prejudice. The court has an alternative, though: if you show good cause for the delay or convince the court that the interest of justice warrants it, the judge can extend the time for service.15New York State Senate. New York Civil Practice Law and Rules Law 306-B – Service of the Summons and Complaint Good cause generally requires proof of reasonable, diligent efforts blocked by obstacles outside your control. Interest of justice is broader and lets the court weigh things like an expired statute of limitations, since a dismissal without prejudice becomes effectively fatal when refiling is no longer possible.
Proof of Service and When Service Is “Complete”
Completing service is only half the work. You have to prove it. CPLR R306 requires the person who performed service to prepare a document specifying the papers served, who was served, and the date, time, address, and manner of delivery.16New York State Senate. New York Civil Practice Law and Rules Law R306 – Proof of Service A sheriff or other public officer files a certificate. Anyone else must sign a sworn affidavit.
What goes into the affidavit depends on the method. For in-hand delivery, it should confirm the papers were given directly to the defendant and include a physical description of the person. For substituted service, it must identify the person who accepted the documents by name (if given) or description, and note the address. For nail and mail, it should describe the door and the mailing. For service on a business, include the name and title of the individual who accepted the papers.
For substituted service and nail and mail, the proof of service has to be filed with the court clerk within 20 days of whichever step happened later. Service under either method is not legally complete until 10 days after that filing.3New York State Senate. New York Civil Practice Law and Rules Law 308 – Personal Service Upon a Natural Person The completion date is the date from which the defendant’s time to respond begins to run, so a miscalculation shifts every downstream deadline in the case.
What Happens If Service Is Defective
Defective service is not something courts wave off. Under CPLR 3211(a)(8), a defendant can move to dismiss the entire action for lack of personal jurisdiction due to improper service.17New York State Senate. New York Civil Practice Law and Rules Law R3211 – Motion to Dismiss Dismissal is usually without prejudice, but if the limitations period has already expired, that distinction stops mattering.
When a defendant challenges how service was carried out, the dispute often goes to a traverse hearing. The process server has to appear and testify about what they did, when, and where, and must bring all records related to the service.18Cornell Law School. New York Comp. Codes R. and Regs. Tit. 22 208.29 – Traverse Hearings Inconsistencies in the affidavit, a vague description of the person served, or gaps in the timeline can all lead a court to invalidate service.
Not every flaw is fatal. CPLR R305 lets a court allow the summons or proof of service to be amended at any time, so long as the amendment does not prejudice the defendant’s substantive rights.19New York State Senate. New York Civil Practice Law and Rules Law R305 – Summons; Supplemental Summons, Amendment A typo in an address on the affidavit is usually fixable. Serving the wrong person, or never serving anyone at all, is not.
Falsifying an affidavit of service carries its own consequences. Under Penal Law 175.30, knowingly presenting a document containing false statements to a public office for filing is a class A misdemeanor.20New York State Senate. New York Penal Law 175.30 – Offering a False Instrument for Filing in the Second Degree A false affidavit can also lead to vacated judgments, sanctions, and license revocation for the process server, and courts in consumer debt and landlord-tenant cases have grown more attentive to catching it.
