SUPREME COURT OF THE STATE OF NEW YORK NEW YORK COUNTY PRESENT: HON. JOHN J. KELLEY PART 56M Justice ---------------------------------------------------------------------------------X INDEX NO. 805102/2025 RICHARD IZZO, MOTION DATE 11/21/2025 Plaintiff, MOTION SEQ. NO. 001 -v- "ONSITE DENTAL", ONSITE DENTAL, LLC., WILSON CHYON, DDS, PETER CHEN, DDS, AMANDA AHMAD, DECISION + ORDER ON DDS and ZI HAN LIU, DDS, MOTION
Defendants. ---------------------------------------------------------------------------------X
The following e-filed documents, listed by NYSCEF document number (Motion 001) 14, 15, 16, 17, 18, 19, 20 were read on this motion to/for DISMISSAL .
In this action to recover damages for dental malpractice, the defendant Zi Han Liu, DDS,
moves pursuant to CPLR 3211(a)(8) to dismiss the complaint insofar as asserted against him
for lack of personal jurisdiction, based upon improper service of process. No party opposes the
motion. The motion is granted, and the complaint is dismissed insofar as asserted against Liu.
The plaintiff commenced this action on April 10, 2025 against Liu, among others.
Although the plaintiff did not file an affidavit of service describing the service of the summons
and complaint upon Liu, Liu submitted his own affirmation, explaining that he was never
personally served with a copy of the summons and complaint. Rather, he asserted that his
parents received a copy of the summons and complaint at their home in Seaford, New York, but
that he did not live there at the time. He averred that, although, during the year prior to his
parents’ receipt of that copy of the summons and complaint, he had been residing in Manhattan,
and had worked at the defendant OnSite Dental, LLC, on West 45th Street in Manhattan, he
had moved to Texas in August 2024, eight months prior to the commencement of this action.
Liu stated that he has lived in Texas since August 2024, and has become licensed to practice

dentistry in Texas. He asserted that a copy of the summons and complaint was never delivered
to a person of suitable age and discretion at either his actual place of business, dwelling place,
or usual place of abode, and that a copy of the summons and complaint was never affixed to the
door at any of those locations.
CPLR 308 requires that service of process upon a natural person must be effectuated
either by personally delivering the summons to that person (CPLR 308[1]), by personally
delivering the summons to a person of suitable age and discretion at that defendant’s actual
place of business, dwelling place, or usual place of abode and mailing the summons to the
defendant’s last known residence or actual place of business (CPLR 308[2]), or, after diligent
attempts unsuccessfully have been made to serve the defendant by one of those two methods,
by affixing the summons to the door of that defendant’s actual place of business, dwelling place,
or usual place of abode and mailing the summons to the defendant’s last known residence or
actual place of business (CPLR 308[4]). CPLR 3211(a)(8) provides that “[a] party may move for
judgment dismissing one or more causes of action asserted against him on the ground that . . .
the court has not jurisdiction of the person of the defendant.” “‘It is axiomatic that the failure to
serve process in an action leaves the court without personal jurisdiction over the defendant’”

Halochos, 189 AD3d 820, 823 [2d Dept 2020]).
As relevant to the instant action, CPLR 308(2) permits delivery of the summons
“within the state to a person of suitable age and discretion at the actual place of business, dwelling place or usual place of abode of the person to be served and by either mailing the summons to the person to be served at his or her last known residence or by mailing the summons by first class mail to the person to be served at his or her actual place of business in an envelope bearing the legend ‘personal and confidential’ and not indicating on the outside thereof, by return address or otherwise, that the communication is from an attorney or concerns an action against the person to be served, such delivery and mailing to be effected within twenty days of each other; proof of such service shall be filed with the clerk of the court designated in the summons within twenty days of either such delivery or mailing, whichever is effected later; service shall be complete 805102/2025 IZZO, RICHARD vs. 'ONSITE DENTAL' ET AL Page 2 of 4 Motion No. 001

“Personal jurisdiction is not acquired absent compliance with both the delivery and mailing
requirements of the statute” (Everbank v Kelly, 203 AD3d 138, 143 [2d Dept 2022] [emphasis
added]). CPLR 308(4) provides that
“where service under paragraphs one and two cannot be made with due diligence, by affixing the summons to the door of either the actual place of business, dwelling place or usual place of abode within the state of the person to be served and by either mailing the summons to such person at his or her last known residence or by mailing the summons by first class mail to the person to be served at his or her actual place of business in an envelope bearing the legend ‘personal and confidential’ and not indicating on the outside thereof, by return address or otherwise, that the communication is from an attorney or concerns an action against the person to be served, such affixing and mailing to be effected within twenty days of each other; proof of such service shall be filed with the clerk of the court designated in the summons within twenty days of either such affixing or mailing, whichever is effected later; service shall be complete ten days after such filing, except in matrimonial actions where service hereunder may be made pursuant to an order made in accordance with the provisions of subdivision a of section two hundred thirty-two of the domestic relations law.”
As with CPLR 308(2), employment of the affix and mail method of service “requires both affixing

As with CPLR 308(2), employment of the affix and mail method of service “requires both affixing

7558, *6 [Sup Ct, N.Y. County, Sep. 12, 2025] [emphasis added]).
Liu established, prima facie, that he was not properly served with process within 120
days after the commencement of the action, as required by CPLR 306-b. Inasmuch as the
plaintiff did not file proof of service with respect to the attempted service upon Liu, the court
cannot apply the longstanding rule that a process server’s affidavit of service is prima facie
evidence of proper service (see Johnson v Deas, 32 AD3d 253, 254 [1st Dept 2006]).
Moreover, inasmuch as the plaintiff did not oppose this motion, he has failed to rebut Liu’s prima
facie showing that service of the summons and complaint was never properly effectuated (see
Campbell v Harun Harunovich & Lavada, Inc., 2020 NY Misc LEXIS 33391, *10 [Sup Ct, Kings
County, Jul. 28, 2020]). 805102/2025 IZZO, RICHARD vs. 'ONSITE DENTAL' ET AL Page 3 of 4 Motion No. 001

Accordingly, it is,
ORDERED that the motion of the defendant Zi Han Liu, DDS, to dismiss the complaint
insofar as asserted against him is granted, without opposition, and the complaint is dismissed
insofar as asserted against him; and it is further,
ORDERED that, on the court’s own motion, the action against Zi Han Liu, DDS, is
severed; and it is further,
ORDERED that the Clerk of the court shall enter judgment dismissing the complaint
insofar as asserted against the defendant Zi Han Liu, DDS.
This constitutes the Decision and Order of the court.
