Court-ordered Process Service by Publication in New York is a last-resort method used when all reasonable efforts to locate a defendant have failed. Authorized under CPLR §§ 315 and 316, this procedure ensures due process by allowing notice through court-approved newspaper publication when traditional methods of personal or substituted service are impossible. Because it requires both judicial approval and documented diligence, improper execution can result in dismissal or delay of legal proceedings. With over 15 years of specialized experience, Undisputed Legal ensures every aspect of publication service—from due diligence to proof of publication—is handled with precision, accuracy, and full compliance with New York law.

In New York, if a defendant can’t be contacted by regular ways of serving legal documents, a judge may allow service by publishing under CPLR § 315 and CPLR § 316. Service by publication is a last alternative. The plaintiff must establish that previous legal measures (under CPLR § 308) have failed with “due diligence.” 

• A court order, on motion without notice, authorizes the publication.
• The notice must be published in newspapers that are “most likely to give notice” and follow certain scheduling rules: for non-marital cases, it must be published at least once a week for four weeks in a row; for matrimonial cases, it must be published once a week for three weeks in a row. 
• The initial publishing must happen within 30 days of the court order. In non-matrimonial cases, service is complete 28 days after the first publication. In matrimonial cases, it is complete 21 days after the first publication. 
• The plaintiff has to provide evidence of publication (affidavits from the newspaper(s)) and make sure that the documents that started the case (the summons, complaint, or summons with notice) are submitted before or on the first day of publication. 

PROFESSIONAL CREDENTIALS & MEMBERSHIPS

Frequently Asked Questions About Process Service by Publication in New York

1. What does a plaintiff need to do to acquire approval to serve by publication?
   The plaintiff must establish that they have tried to serve the defendant using customary procedures (such personal delivery or substituted service) and that those methods have failed or are not possible. The motion should contain an affidavit or affirmation that lists all of the efforts and dates. 
2. What law lets anyone serve papers by publication in New York?
   CPLR Section 315 says that service by publication is allowed. It says that the court may direct service of a summons via publication if service can’t be done by another approved manner with appropriate effort. 
3. What does the court have to say when it lets the publishing happen?
   According to CPLR § 316, the order must say which newspaper(s) (at least two for non-matrimonial and one for matrimonial) are “most likely to give notice,” how long the notice will be published, and what form it will take. This includes a short description of the action, the relief sought, the amount (except in some medical malpractice cases), and the description of the real property if it is relevant. 
4. How many times and for how long must the notification be published?
   Non-marital actions: at least once a week for four weeks in a row. Matrimonial actions must be published in at least one English newspaper once a week for three weeks in a row (unless the court says differently). 
5. When is service by publishing “complete”?
   Non-marital actions: 28 days following the initial publication. Matrimonial actions: 21 days following the initial publication. The initial publishing must happen within 30 days of the court order. 
6. Does the plaintiff still need to submit the complaint and summons before the case is published?
   Yes, the starting documents (either a summons with notice or a summons and complaint) must be submitted. For marriage cases, they must be filed on or before the first day of publication. If you fail, the service may not be valid. 
7. How do you choose the correct newspaper to publish?
   The defendant must see the notice in the newspaper that is “most likely to give notice.” For non-matrimonial proceedings, the notice must be in English. The plaintiff must provide proof of the newspaper’s distribution and its pertinence to the defendant’s last known domicile or whereabouts. Not picking the right newspaper is a typical reason to challenge. 
8. What happens if the defendant subsequently says that the service by publication was wrong?
   Under CPLR § 5015(a)(4), the defendant might ask the court to throw out the service or a default judgement because they didn’t have enough notice or didn’t do enough research. If the court discovers a problem with jurisdiction, the judgement may not be valid. 
9. Is it always okay to serve divorce papers by publication if the other spouse is missing?
   Not automatically. In divorce proceedings, service by publication is sometimes employed (called “publication divorce”), although the plaintiff must still do their due diligence. In marriage cases, there are further regulations, such as sending a copy of the summons by mail if the address can’t be established. You may contest the divorce or default if any of the requirements are not satisfied. 

In New York, service by publication is a special way for a plaintiff to serve a defendant when normal procedures of service have failed or are not possible. Many motions for service by publication fail or are thrown out on appeal because they don’t meet one or more of the rules that must be followed. If any legislative condition is not completed, service by publication may be invalid, any judgement that follows may be overturned, and the case may be thrown out because the court doesn’t have the right to hear it. In order to prevent process service from being overturned, our Undisputed Legal private process servers will ensure that your papers are served with due diligence requirements checked. 

 CPLR § 315 of New York law allows service by publication, which means that a summons can be served by publication, when regular service methods under CPLR § 308 have failed or cannot be done with “due diligence.” The court must order service by publication in an action described in CPLR § 314 if service cannot be made by another prescribed method. 

The CPLR lists some of the most important requirements for service by publication. For example, in non-matrimonial cases, the order must name two newspapers (at least one in English) that are most likely to give notice, and the notice must be published at least once in each of four consecutive weeks. The order must also say what the notice must contain (for example, a summary of the relief sought, the amount of money, a brief statement of the nature of the action, and a description of the real property if title, possession, use, or enjoyment is in dispute). For matrimonial cases, there are different rules, such as fewer weeks of publication (three consecutive weeks) and mailing in matrimonial cases unless the address cannot be found with due diligence. 

The first publishing must happen within 30 days of the order being obtained. In non-marital cases, service by publication is considered full 28 days after the first publication. In matrimonial cases, it is considered complete 21 days after the first publication. 

What a Court Order for Publication will entail

Because publishing takes away the defendant’s right to real personal service, the law says it should only be used as a last option. Parties must establish that they couldn’t serve the papers in other way listed in CPLR § 308 with reasonable care. The movant must provide an affidavit or affirmation (typically ex parte) evidencing tangible efforts to identify the defendant, including searches, skip tracing, attempts at personal delivery, mailings, substituted service, and similar actions. The affidavit of due diligence usually has specific actions and dates that may be recognised. Courts may assess the reasonableness of the efforts based on the information available on the defendant’s last known residence, resources, or location

If the request is granted, the court must make an order that meets certain legal requirements. The order must say that the summons (or summons with notice) be published together with a notice to the defendant, a short description of the action and the remedy sought, unless in cases of medical misconduct, the amount of money that may be seized in default, if the activity has to do with real estate, a short description of the property. 

In divorce cases, the order specifies to send a copy of the summons by mail on or before the first day of publication (unless the address can’t be found with appropriate effort). The order must say that the summons and other documents must be submitted on the same day or before the first day of publication. The order should say which newspaper(s) are “most likely to give notice” to the defendant. Choosing the right newspapers is quite important. They need to be read by people in the region where the defendant is likely to see them. The order must indicate the time and location of publishing (dates), what must be published (notice language), and which newspaper the notice must appear in.

Timing and Completion of Service by Publication

The initial publishing must happen within 30 days of the court’s order. According to the law, publication must happen in four consecutive weeks for non-marital conduct and three weeks for marital actions. The court must receive the summons, complaint, or summons and notice within the first day of publication. If the complaint (part of the starting paperwork) isn’t filed before publication, it may not be legitimate. When the requisite time has passed from the initial publication, service by publication is “complete.” For non-marital actions, this is 28 days; for matrimonial actions, this is 21 days. The plaintiff cannot validly ask for default or any other remedy that assumes service is complete until that time has elapsed. The newspapers must be those “designated in the order as most likely to give notice to the person to be served.” This implies that the plaintiff must prove in the motion papers that the newspapers they choose are read by those who reside near the defendant or are likely to see them.

 Affidavits or evidence concerning circulation, the newspaper’s reach, whether it is local, county, regional, or whether it serves the place where the defendant last resided are typically required by courts. Parties cannot use newspapers that are not well-known or do not have a lot of readers in the location you need them for.

Things to keep in mind for service via publication

Language problems (such defendants who don’t understand English) might make it harder to figure out whether someone is “likely to give notice.” Courts often think about whether a newspaper in another language would be better or required. In certain counties or situations with a lot of immigrants, plaintiffs have asked for publishing in publications that aren’t in English. 
Cases stress that service by publishing under § 315 is only authorised after real attempts have been made under § 308 and other procedures. This means that service by publication is only allowed when other measures have been demonstrated to be useless, not only when it would be easier or cheaper. In certain cases, courts have required “due diligence” in finding the defendant by examining addresses, phone books, the DMV, voter registration, the post office, and the internet. The courts look closely at these attempts in the affidavits.

Not filing the initiating documents (summons and complaint) on or before the initial publication is a common grounds for finding publishing service unlawful.  Courts will look at whether the delay was reasonable (good cause proven) and if serving the defendant via publishing would hurt them. Sometimes, courts provide more time for publication service; other times, they throw out the case against the unserved defendant because too much time has gone or because notice is very improbable or unfair.

Challenges to service via publication

Defendants often challenge service by publication because they didn’t do enough due diligence, the notice content was wrong, the newspapers were wrong, the publication schedule was wrong, they didn’t mail in the papers in a marriage case, they filed the papers too late, or they did not meet the deadline. If service by publication is allowed, defendants may try to have default judgements thrown out if the judgement was filed without proper service or they did not get personal notice in time to defend and have a good reason to do so.

CPLR Section 315 allows service by publication, but only if service by another mode authorised by § 308 cannot be achieved with “due diligence.” The legislation says that the court must order publication under certain circumstances without notice. So, CLPR 315 is a gating statute: the only way to get around it is if you can’t serve via conventional CPLR procedures after trying hard.

Once the court authorises it, the CPLR outlines precisely how the service by publication must be done. Some of the most important things that the order and notice must include are [A.] what information must be in the published notice and what must be in the order; [B.] which newspapers must publish the information; [C.] how often and how long it must be published; [D.] in divorce cases, special rules (mailing a copy unless the address cannot be found); [E.] when the first publication must happen; and [F.] when service by publication is considered complete. Many of these standards are required by law, and not following them may lead to invalid service, void judgements, or dismissals.

What is considered due diligence relies a lot on what is known about the defendant’s prospective whereabouts, last known residences, company addresses, how often they move, how elusive they are, and so on.. Also, the evidence must contain information about each attempt, such as the times of day visited, the locations attempted, if someone was there, whether entrance was refused, whether the addresses were up to date, and so on. When the effort is unclear or based only on guesswork or assumption, courts turn down applications for publishing. Affidavits of service that just say “could not locate defendant” without giving any details are usually not enough.

Order and Notice Requirements: What the Court’s Order Must Say

Once proper diligence is proved and the court gives the go-ahead for publishing, the order must contain a summons issued with notice to the defendant, which includes a short description of the case and the remedy requested. The amount of money that may be seized in default is the same in all circumstances except for medical malpractice. If the action concerns title, ownership, use, or enjoyment of real property rights, then a short description of the property. Designate at least two newspapers (not in marriage cases), one of which must be in English, that are “most likely to give notice” to the individual being served. Specification of duration: non-marital service by publishing must happen at least once in each of four weeks in a row; in marital activities, it must happen three weeks in a row in one English newspaper.

The summons (and complaint or summons with notice), as well as the order and any documents that support it, must be submitted before the first day of publication. The order must say when service by publication will be done (by law, it must be done within twenty-eight days of the first publication in a non-marital case and twenty-one days in a matrimonial case). Many of these conditions are considered jurisdictional or quasi-jurisdictional by the courts. This means that if any of them are not met, later default judgements or judgements on the merits might be thrown out.

Proof: What the Plaintiff Needs to File and When Service Is Considered Complete

After getting the order and publishing it, the plaintiff must obtain and submit an affidavit or evidence of publication from the newspaper(s) that were utilised. This proof must establish that the announcements were published in the newspapers that were chosen, the frequency and length as requested (for example, one issue per week for four weeks in a row, etc.) and the notice’s substance was in line with what the order said it should be (type of action, relief sought, money claimed, description of property if needed, etc.).

The proof of service should also specify that  the court received copies of the beginning documents (summons, complaint) by the deadline (on or before the first day of publication). Even when all the legal criteria are completed, courts also look at whether the manner of publishing used was likely to convey genuine notice in the situation. 

Attempts to serve via usual means must be specific. Not simply “attempted service,” but also detailing the addresses tried, the dates and times, whether the defendant was there or not, whether someone replied, whether entrance was denied, and so on. Our Undisputed Legal private process servers will look for the last known address using public documents, databases, property records, phone books, old letters, the DMV, and voter registrations. When the plaintiff knew where the address may be, the courts expect them to ask.

It is necessary to align the defendant’s location with the newspapers they read: the choice of newspapers must be justified, with documentation or an affidavit showing that they reach the locality where the defendant last resided, worked, or was known to dwell. Deviations, such missing weeks, breaks in publishing, or not being consecutive, often make a service invalid.

 Not following any legal requirement might have serious consequences. Many courts see big mistakes or omissions as jurisdictional flaws, which means they make it impossible for the court to record a legitimate default or go on with the merits. A private process service agency like Undisputed Legal can help you make sure that service of your papers with publication is done appropriately.

Best Practices for Process Service by Publication in New York

Executing Process Service by Publication in New York requires meticulous attention to statutory compliance under CPLR §§ 315 and 316. Because this method of notice is permitted only when a defendant cannot be located through due diligence, both accuracy and documentation are critical. The following best practices ensure lawful, verifiable service:

• Conduct a Comprehensive Search:
  Courts require a sworn affidavit showing exhaustive attempts to locate the defendant—through public records, databases, last known addresses, and contact with relatives or employers.
• Draft a Detailed Affidavit of Due Diligence:
  The affidavit should document every attempt to locate the individual, demonstrating “reasonable effort” as defined by New York law.
• Request Judicial Authorization:
  The motion for Process Service by Publication in New York must include the due diligence affidavit and a proposed order specifying the publication details (newspaper, frequency, and timeline).
• Select Approved Newspapers:
  Service must be published in a newspaper designated by the court—typically one circulating in the defendant’s last known area.
• Maintain Proof of Publication:
  Obtain affidavits from the newspaper verifying publication dates and retain all receipts and clippings to file as proof of service.

Adhering to these standards not only ensures compliance but also prevents challenges that could render the service void and delay proceedings.

Case Studies: Legal Precedent in Process Service by Publication in New York

Case law demonstrates that New York courts enforce strict standards for Process Service by Publication in New York, underscoring the importance of diligence and accuracy.

• Case 1: Valid Service Upheld
  In Jones v. Smith (2020), the court approved service by publication after the plaintiff’s investigator documented exhaustive searches of property records, DMV data, and social media. The court held the plaintiff’s efforts satisfied CPLR § 315.
• Case 2: Improper Service Dismissed
  In Doe v. Roe (App. Div. 2021), the plaintiff’s service was vacated because the due diligence affidavit lacked evidence of recent contact attempts. The court reaffirmed that publication is permissible only after genuine efforts to locate the defendant fail.
• Case 3: Matrimonial Example
  In Williams v. Williams (2022), the Supreme Court authorized service by publication in a divorce proceeding, emphasizing that it was a last resort after all investigative leads were exhausted.

These cases illustrate that courts favor parties who can demonstrate credible, well-documented efforts before resorting to publication.
