Full Text of CPLR 308
Plain-English Summary
Section 308 sets out five methods for serving an individual, and they aren't interchangeable menu options -- several depend on the ones before them having failed. The first is the simplest: hand the summons directly to the person anywhere in New York. The second is deliver-and-mail, sometimes called leave-and-mail: hand the summons to a person of suitable age and discretion at the defendant's actual place of business, dwelling place, or usual place of abode, then mail a copy to the defendant's last known residence, or mail it first class to the workplace in an envelope marked "personal and confidential" that gives no outward sign it's from a lawyer or concerns a lawsuit. The delivery and the mailing have to happen within twenty days of each other, proof of service has to be filed within twenty days of whichever came later, and service isn't complete until ten days after that filing. A third method allows delivery to an agent the defendant designated for service under rule 318.
The fourth method, affix-and-mail (widely known as "nail and mail"), is available only when the first two methods can't be completed despite due diligence. It works like deliver-and-mail but substitutes affixing the summons to the door of the defendant's business, dwelling, or usual abode for handing it to a person, with the same twenty-day mailing window, twenty-day filing deadline, and ten-day completion delay. The fifth method is a catch-all: if service is impracticable under the first, second, and fourth methods, a court can direct whatever manner of service it thinks fit, on a motion made without notice to the defendant.
"Due diligence" is not defined by a formula, but it means a process server has to make a genuine effort to find the defendant, or someone of suitable age at the defendant's home or work, before resorting to affix-and-mail. CPLR 306(c) reinforces that requirement by making the process server document the dates, addresses, and times of the earlier attempts. Paragraph six also defines "actual place of business" to include any location the defendant has held out, through regular solicitation or advertisement, as a place of business -- closing a gap for people who run a business without a fixed office.
Few sections of the CPLR generate as much litigation as this one. The precise sequencing, the twenty-day windows, the mailing requirements, and the due-diligence standard for affix-and-mail service are exactly the technical details that turn into motions to dismiss for lack of jurisdiction or motions to vacate a default judgment. Anyone relying on substitute or affix-and-mail service should build a paper trail that would satisfy CPLR 306's proof-of-service requirements before the ten-day clock even starts running.
Frequently Asked Questions
How do you serve a summons on an individual in New York?
By personal delivery to the individual anywhere in the state, by deliver-and-mail to a person of suitable age and discretion at the individual's home or business plus a follow-up mailing, by delivery to a designated agent, by affix-and-mail when the first two methods can't be completed with due diligence, or by a method the court directs when even that is impracticable.
What is "nail and mail" service under CPLR 308?
It's the fourth method listed in the statute: affixing the summons to the door of the defendant's actual place of business, dwelling place, or usual place of abode, then mailing a copy, used only when personal delivery and deliver-and-mail service can't be completed despite due diligence.
What counts as a person of "suitable age and discretion" for substitute service?
The statute doesn't set a fixed age or test; courts look at whether the person who accepted the summons at the defendant's home or business was old enough and responsible enough to be expected to pass it along to the defendant.
How much time do I have between delivering and mailing the summons under CPLR 308?
The delivery (or affixing, for nail-and-mail service) and the mailing must be completed within twenty days of each other, and proof of service must be filed within twenty days of whichever happened later.
When can a court authorize an alternate method of service under CPLR 308(5)?
When service is impracticable under the personal delivery, deliver-and-mail, and affix-and-mail methods, a court can direct another manner of service on a motion made without notice to the defendant.
What does "due diligence" mean before using affix-and-mail service?
It means the process server made a genuine effort to complete personal delivery or deliver-and-mail service first, such as attempting service at different times or days, before resorting to affixing the summons to the door.
When is service under CPLR 308 considered complete?
For deliver-and-mail and affix-and-mail service, service is complete ten days after proof of service is filed with the clerk of the court named in the summons.
Advisory Committee Notes
(See also Advisory Committee note preceding § 301 under subheadings “Service of summons generally” and “Substituted service.”).
The provision in paragraph 1 for service by personal delivery to the party in person is substantially the same as that of CPA § 225(3).
The substituted service provisions found in the CPA and their requirement that a court order be obtained are omitted. Such orders are generally granted as a matter of course and to require them is wasteful of both the lawyer’s and the court’s time. However, the replacement for substituted service will only be used if service by delivery to the person to be served cannot be made with due diligence. The replacement for the method of substituted service provides for mailing plus either affixing the summons on the door, or delivery of the summons to a person of suitable age and discretion, at the place of business, dwelling house or usual place of abode of the person to be served. This method is based partly upon the method for service used in summary proceedings to recover real property. It is calculated to insure that actual notice is given to the defendant. The “due diligence” which must be used in attempting to deliver personally to the person to be served before substituted service may be made is based upon the former CPA requirements. A number of attempts to serve will be sufficient. They should be specified in the affidavit of service in much the same way that the former affidavit on a motion for an order for substituted service specified them. The requirement of mailing is not found in the Federal rules and rules of other states permitting service by delivery to a person of suitable age and discretion. See Fed R Civ P 4(d)(1); Pa Stat Ann tit 12, RCP 1009(b) (Purdon) (1951); NJ R Civ P 4:4-4. See also CPA § 231(1) (mailing is not required where summons left with a “person of proper age”). However, the Committee has accepted the suggestions of a substantial number of members of the bar at public hearings and by private communication that mailing be required.
1986 Recommendations of Advisory Committee on Civil Practice:
The Committee recommends the repeal of the unnumbered last paragraph of CPLR 308, which mandates that a notice of default judgment, in addition to that contained in the summons, be served on a defendant who is a natural person in an action arising out of a consumer credit transaction, and the transfer of this provision, clarified and improved, into CPLR 3215. This measure does not propose, however, to alter in any essential aspect the protection against sewer service which the present law, enacted by chapter 344 of the Laws of 1977, provides.
The language of the 1977 legislation, although salutary in intent, has given rise to technical problems. The procedure would be improved by the recommended changes, as follows:
1. The application of the provision to actions for nonpayment of a contractual obligation would be changed to those arising from a consumer credit transaction. This change is consistent with the purpose of the provision to protect against sewer service, which is rare in contract actions except those arising from consumer credit transactions.
2. Actions affecting title to property would be excepted. Title companies are justly apprehensive that, in such actions, the requirement to give additional notice could be troublesome in that inadvertent failure to do so allows vacatur of the default judgment, thus generating challenges to title many years after entry of judgment.
3. In conformance with general practice, provision would be made for service of the additional notice by the employee of an attorney, as well as by the party or his attorney, as at present.
4. It would be made clear that the additional notice may be mailed not only after, but also simultaneously with service of process.
5. Where there has been compliance with the additional notice requirements, failure of the defendant to receive such notice shall not preclude entry of, or invalidate, the default judgment. Without this provision, the plaintiff would be penalized unfairly by being prevented from obtaining a judgment where it is impossible to serve the additional notice on the defendant.
This measure would relocate the provisions governing default notices, now located in CPLR 308 (service of process), to a new paragraph 3 of CPLR 3215(f) (notice requirements for entry of default judgment), where it more logically belongs. CPLR 3215(e) would be amended to correct an obsolete cross-reference to CPLR 308; and a number of other minor verbal and mechanical improvements would also be made.
1994 Recommendations of Advisory Committee on Civil Practice:
The Committee recommends that a new subdivision 6 be added to CPLR 308, governing personal service upon a natural person, to provide that where a person designates, through regular solicitation or advertisement, an address, including a private mail drop, as the address to which business correspondence should be mailed, indicating this on business letterhead, or in the telephone yellow pages, or on business vehicles, etc., such address, including a mail drop, should suffice as “the actual place of business” for the purpose of receiving service of process.
Frequently, for purposes of convenience, persons doing business select a commercial mail drop to receive their business correspondence. The mail drop affords an actual business address, not a box number, and this address may be placed on the person’s business letterhead, advertisements in the yellow pages and elsewhere, and printed on the business’s commercial vehicles. The commercial mail drop services many businesses, and technically may not be the “actual place of business” of the persons who receive mail there. Neither is the commercial mail drop an agent designated to receive service. Plaintiffs with claims against mailing a summons to a person at “his or her actual place of business’’, have no way of knowing that the so-called ”business address“ is a mere mail drop, and many unknowingly make improper service by serving the defendant at the mail drop address.
The Committee believes that where a person publicly designates a mail drop address as his or her place for receiving business mail, a person having a claim against such person should be able to rely upon the address as constituting the person’s “actual place of business” as understood in CPLR 308. New subdivision 6 would so provide.
