DECISION AND ORDER Currently before the Court is the motion of Defendant 43 North Broadway, LLC (“43 North”) to use alternative means to effect service of its crossclaims on Defendants Thomas Ficara (“Ficara”) and Margate Entertainment LLC (“Margate”) (collectively, the “Crossclaim Defendants”), and for an extension of time of the deadline to complete service of the crossclaims. ECF No. 68 (“Mot.”). After the motion was filed, 43 North also moved for permission to serve discovery requests on the Crossclaim Defendants by the same alternative means. ECF No. 76. Both motions are unopposed. For the reasons that follow, the motions are GRANTED, with the particular limitations set forth below. BACKGROUND On November 7, 2023, Plaintiffs Charly Acquisitions, Ltd. and Charly Trademarks, Ltd. (collectively, “Charly”) commenced this action against 43 North, and on July 11, 2024, filed a first amended complaint, which added Ficara and Margate as new defendants in the action. ECF No. 51. On July 25, 2024, 43 North filed an answer to the first amended complaint which included crossclaims against Ficara and Margate. ECF No. 56. Summonses for the crossclaims were issued for Ficara and Margate on October 9, 2024. ECF Nos. 66, 67. A. 43 North’s Attempts to Personally Serve Ficara On October 17, 2024, a process server employed by 43 North attempted personal service on Ficara at 21900 Neuralia Road, California City, CA 93505, a residential address where, according to 43 North, Ficara previously had been served by Charly. Mot. at 2 & Ex. 2; see ECF No. 58. The process server “spoke to Alan Doe who advised that [Ficara] has not lived at this location and his current whereabouts are unknown.” Id. Ex. 2. According to 43 North, the process server was able to identify “Alan Doe,” from a photograph found on Margate’s website, as Alan S. Rosenberg. Mot. at 2 & n. 1. Rosenberg is the individual who accepted service of the first amended complaint on Ficara’s behalf at 21900 Neuralia Road on August 27, 2024. Id. at 2 & n.1, Ex. 1; see ECF No. 58. The process server subsequently made two additional attempts at personal service on Ficara at the 21900 Neuralia Road address. Id. at 2 & Ex. 3. On November 8, 2024, the process server went to the residence and spoke with John “Doe,” who refused to provide his last name; John “Doe” stated that Ficara no longer resided at that address, but told the process server that Ficara “still keeps his car on the property and gets mail” there. Id. Ex. 3. On November 13, 2024, the process server made a final attempt at service at 21900 Neuralia Road, but this time, “there was no answer, sound or movement inside the residence,” and there were “no new vehicles on the property.” Id. In October and November 2024, 43 North asserts that it also had the process server make several attempts at personal service on Ficara at what 43 North describes as “an alternative address for Ficara in Margate’s Articles of Organization” — 9031 California City Boulevard, California City, CA 93505.1 Id. at 2-3 & Exs. 4, 5. On October 19, 2024, the process server went to the address, but there was no answer at the door. Id. at 2 & Ex. 4. The lights in the home were off but there was a dog in the yard and a vehicle in the driveway. Id. Ex. 4. On October 21, 2024, the process server made two attempts at service. At 2:35 p.m. that day, the process server spoke to the occupant of the property, Katie “Doe,” who refused to provide her last name; Katie “Doe” stated that “the defendant lives around the corner,” but did not provide an exact address. Id. At 4:40 p.m. that day, the process server “attempted to obtain the subject’s new address but no one answered the door.”2 Id. On November 8, 2024, the process server again attempted service on Ficara at the 9031 California City Boulevard address. Id. Ex. 5. There was no answer at the home, and there was a lock on the gate to the yard and front door, but there was a white truck in the driveway. Id. On November 9, 2024, the process server returned, and again, there was no answer at the door or sound inside the home — “no change from previous attempt.” Id. On November 11, 2024, the process server made a third attempt and this time spoke to a woman named “Kelly,” who stated that Ficara had never lived at that address and that the owner was someone by the name of Josh Meister. See id. She added that she “does not get mail for Thomas [Ficara] here” and “doesn’t know where he lives.” Id. B. Attempts to Communicate with Ficara via Email To determine whether email could serve as a means of alternative service, 43 North’s counsel sent an email to [email protected] on December 5, 2024. ECF No. 74 (Declaration of Rachel A. Levin (“Levin Decl.”)) 6 & Ex. 3. 43 North’s counsel received a response that same day in which the user of the “[email protected]” email address acknowledged awareness of the lawsuit: “Your client robbed me of $250,000. I could solve your case in ONE MINUTE, but why should I?” Id. On December 5, 2024, counsel for 43 North also sent an email to [email protected], the email address used by Charly to send subpoenas to Ficara in May 2024, in response to which Charly “did not receive a mailer daemon notice, or any other indication that the email failed to deliver.” Id. 7 (citing ECF No. 42); see Hakim v. Accenture U.S. Pension Plan, 735 F. Supp. 2d 939, 953 (N.D. Ill. 2010) (“As anyone who has received a ‘failed delivery’ e-mail from mailer-daemon knows, various problems can prevent the delivery of an e-mail message.”). 43 North’s counsel likewise “did not receive a bounce-back or mailer daemon notice” in response to its December 5, 2024 email. Levin Decl. 9. C. 43 North’s Attempts to Serve Margate Margate is a limited liability company (“LLC”) registered in Pennsylvania. Id. Ex. 6. 43 North attempted service on Margate at the address registered for the LLC as reflected on the Pennsylvania Department of State business entity search website — 108A Erickson Avenue, Essington, PA 19029. Mot. at 3 & Exs. 6, 7; Levin Decl. 12 & Ex. 6. On October 16, 2024, a process server went to the address and found a business there called ASAP. Mot. Ex. 6. Margate was neither known nor located at this address. Id. On November 8, 2024, a different process server went to the address and found a different business there called Anesthesia Services. Id. Ex. 7.3 According to 43 North, after the initial attempt to serve Margate at its registered business address was unsuccessful, 43 North also attempted to serve Margate at other locations. Specifically, according to 43 North, the two attempts at service at the 21900 Neuralia Road address in November 2024 were also attempts to serve Margate. Mot. Ex. 3. It appears that the basis for attempting to serve Margate at this address was either that (i) Ficara — who 43 North hoped to find at this address — should be considered an agent of Margate for purposes of service of process; or that (ii) Charly was able to serve Margate at 21900 Neuralia Road by delivering the first amended complaint to Rosenberg, who accepted service on behalf of both Ficara and Margate on August 27, 2024.4 See ECF Nos. 58, 59.5 On November 8, 2024, John “Doe” told the process server that he was not authorized to accept service on behalf of Margate. See Mot. Ex. 3. 43 North also attempted to serve Margate at the 9031 California City Boulevard address, apparently based on the fact that this address was listed in Margate’s Articles of Organization. But this address is described elsewhere in 43 North’s motion papers as “an alternative address for Ficara” listed in the Articles of Organization, and it is not clear what basis 43 North has for considering this address to be a potentially valid address for service of process on Margate.6 D. Attempts to Communicate with Margate Representatives via Email On December 5, 2024, 43 North’s counsel sent an email to [email protected], the email address provided on the “Contact Us” webpage of Margate’s website found at http://www.margateentertainmentllc.com/MargateHome/contact-us/ [https://perma.cc/D7Z9-M6S9] (last visited Dec. 30, 2024), see Levin Decl. 13 & Ex. 7, and did not receive a bounce-back or mailer daemon notice, id. 14. * * * * * * * * * * As noted above, 43 North filed its crossclaims on July 25, 2024. ECF No. 56. Pursuant to Rule 4(m) of the Federal Rules of Civil Procedure, 43 North had 90 days to effect service on Ficara and Margate, which made October 23, 2024 the deadline to complete service. See Fed. R. Civ. P. 4(m). 43 North now seeks an extension of time to effect service of the crossclaims on Ficara and Margate, as well as permission to effect service of the crossclaims and 43 North’s discovery demands to Ficara and Margate by the combined alternative means of certified mail and email. See Mot. at 5; Levin Decl. 3 & n. 1; ECF No. 76. DISCUSSION I. Legal Standards Pursuant to Rule 4(e) of the Federal Rules of Civil Procedure, service of process on an individual in the United States may be effected in accordance with the laws of the state where the district court is located or where service is made.7 Fed. R. Civ. P. 4(e)(1). Under New York law, service of process on a natural person may be accomplished by: (1) personal service; (2) delivery 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”; (3) service on an agent; or (4) so-called “nail and mail” service, i.e., affixing the summons to the door of the person’s “actual place of business, dwelling place or usual place of abode” and mailing it to his or her last known residence or actual place of business. N.Y. C.P.L.R. (“CPLR”) §§308(1)-(4). When traditional methods of service such as personal service or “nail and mail” service become “impracticable,” service may be made “in such manner as the court, upon motion without notice, directs.” CPLR §308(5). Pursuant to Rule 4(h) of the Federal Rules of Civil Procedure, service of process on a “domestic or foreign corporation, or a partnership or other unincorporated association that is subject to suit under a common name” may be effected “in the manner prescribed by Rule 4(e)(1) for serving an individual,” or “by delivering a copy of the summons and of the complaint to an officer, a managing or general agent, or any other agent authorized by appointment or by law to receive service of process….” Fed. R. Civ. P. 4(h)(1)(A)-(B). As noted above, Rule 4(e)(1) permits service in accordance with the laws of the state where the district court is located or where service is made. Fed. R. Civ. P. 4(e)(1). Because 43 North focuses exclusively on the procedures for serving an LLC under New York law, the Court again concentrates its analysis on the relevant New York statutes, rather than any applicable law from California or Pennsylvania.8 Under New York law, service of process upon a foreign LLC is to be made by delivering a copy personally to (i) any member of the limited liability company in this state, if the management of the limited liability company is vested in its members, (ii) any manager of the limited liability company in this state, if the management of the limited liability company is vested in one or more managers, (iii) to any other agent authorized by appointment to receive process, or (iv) to any other person designated by the limited liability company to receive process, in the manner provided by law for service of a summons as if such person was a defendant. CPLR §311-a(a). The CPLR additionally states that “[i]f service is impracticable…, it may be made in such manner as the court, upon motion without notice, directs.” CPLR §311-a(b). “The meaning of ‘impracticable’ depends on the facts and circumstances of a particular case. In general, plaintiff must make some showing that the other prescribed methods of service could not be made.” Sirius XM Radio Inc. v. Aura Multimedia Corp., 339 F.R.D. 592, 593 (S.D.N.Y. 2021) (cleaned up). “In shaping an appropriate method for alternate service, the Court must ensure that the alternate method complies with constitutional due process by being reasonably calculated, under the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections.” Id. (cleaned up). II. Analysis A. Service Upon Ficara 43 North made multiple attempts to serve Ficara without success. In light of 43 North’s “demonstrated inability to effectuate service through traditional means, the Court concludes that service pursuant to the particular methods specified by New York State law is impracticable and that alternative service is appropriate.” Marvici v. Roche Facilities Maint. LLC, No. 21-cv-4259 (PAE) (JLC), 2021 WL 5323748, at *3 (S.D.N.Y. Oct. 6, 2021) (cleaned up). Service on Ficara by alternative means is appropriate for the added reason that Ficara already knows about the pending lawsuit — he was served with the first amended complaint by Plaintiffs in August 2024, and the user of the “[email protected]” email address demonstrated an obvious familiarity with the matter in the December 5, 2024 communication with 43 North’s counsel. See ECF No. 58; Levin Decl. Ex. 3; see Marvici, 2021 WL 5323748, at *5 (“Service by alternative means is all the more reasonable where a defendant demonstrably already has knowledge of the lawsuit.”). 43 North requests permission to effect service upon Ficara through the alternative methods of (1) certified mail sent to 21900 Neuralia Road in California City, and (2) email sent to [email protected] and [email protected]. See Mot. at 5; Levin Decl. 3 & n. 1. “In general, courts have authorized alternative service via certified mail to a last known address.” Marvici, 2021 WL 5323748, at *3. Despite 43 North’s numerous unsuccessful attempts to serve Ficara at 21900 Neuralia Road, on November 8, 2024, the process server spoke with an occupant at the address who stated that even though Ficara no longer resided there, he still receives mail there. Mot. at 2 & Ex. 3. Accordingly, service upon Ficara by certified mail sent to 21900 Neuralia Road is reasonably calculated to provide Ficara with notice of the crossclaims. “Service by email is appropriate when it can be demonstrated that such service is likely to reach the defendant.” Wells Fargo Bank, N.A. v. Johnson, No. 20-cv-5496 (LDH) (LB), 2021 WL 9678391, at *2 (E.D.N.Y. Feb. 9, 2021) (cleaned up). “Service using this method has been upheld in cases where the proposed email address was undisputedly connected to the defendant and used for business purposes.” Id. (cleaned up). There is evidence that Ficara receives email at both [email protected] and [email protected]. 43 North notes that [email protected] is the email address through which Curt Frasca, 43 North’s principal, previously had indirect business communications with Ficara in 2019. Levin Decl. 4 & Ex. 1. In addition, a press release issued by TVS Television Network on November 29, 2024 includes, as part of Ficara’s contact information, the email address [email protected]. Id. 5 & Ex. 2. Lastly, as noted above, 43 North’s counsel sent an email to [email protected] on December 5, 2024, and received a response that same day that demonstrates a familiarity with this matter. Id. 6 & Ex. 3. As also noted above, [email protected] was the email address used by Charly to send subpoenas to Ficara, in response to which Charly “did not receive a mailer daemon notice, or any other indication that the email failed to deliver.” Id. 7 (citing ECF No. 42). Similarly, when counsel for 43 North sent an email to [email protected] on December 5, 2024, she “did not receive a bounce-back or mailer daemon notice.” Id. 9. Courts have found that service via email is reasonably calculated to provide notice when test emails to viable addresses do not generate bounce-back responses. See Toyo Tire & Rubber Co., Ltd. v. CIA Wheel Grp., No. 15-cv-246 (DOC), 2016 WL 1251008, at *3 (C.D. Cal. Mar. 25, 2016) (“Many cases have found service of process by email to be reasonably calculated to provide actual notice when the test email is not returned as undeliverable or bounced back.”) (citing cases); see also Fusa Franchisor SPV LLC v. SGB, Inc., No. 23-cv-2673 (AB), 2023 WL 8125854, at *2 (C.D. Cal. Aug. 28, 2023) (finding that plaintiff had demonstrated that service by email to defendants was “reasonably calculated to provide notice to the party to be served” where emails sent to addresses at which plaintiff last tried to contact defendants “did not receive a ‘bounce back’ response”). Moreover, press releases issued by TVS Television Network on August 5, 2024 and November 16, 20249 include the email address [email protected] as part of Ficara’s contact information. Id. 8 & Exs. 4, 5. Based on the foregoing, 43 North has established that the email addresses [email protected] and [email protected] are undisputedly connected to Ficara, that service to these email addresses is likely to reach him, and that such service is reasonably calculated to provide Ficara with notice of the crossclaims. The Court therefore approves alternative service by this method as well. B. Service Upon Margate 43 North made multiple unsuccessful attempts to serve Margate, and on balance the Court finds that 43 North has established that service by traditional methods is impracticable. As explained above, under New York law, service on an LLC may be made on “any other agent authorized by appointment to receive process,” or “any other person designated by the [LLC] to receive process,” CPLR §311-a(a), or on “an officer, a managing or general agent, or any other agent authorized by appointment or by law to receive service of process….,” Fed. R. Civ. P. 4(h)(1)(B). Here, 43 North made two attempts to serve Margate at the Pennsylvania address where Margate is formally registered to conduct business, only to learn that Margate could not be found at that address. 43 North also made several unsuccessful attempts to serve Margate at the 21900 Neuralia Road and 9031 California City Boulevard addresses, presumably based on the understanding that Ficara — who 43 North also attempted to serve at those addresses — is an agent authorized to accept service on Margate’s behalf. Unfortunately, the evidence presented by 43 North that Ficara is an agent authorized to accept service for Margate is thin. 43 North states only that “[u]pon information and belief, Ficara is a managing principal of Margate,” citing the letter filed by Charly’s counsel when Charly previously sought leave to serve subpoenas on Ficara and Margate by alternative means. Mot. at 3 (emphasis added); see ECF No. 42 at 3 (“Ficara is a managing principal of Margate…”).10 43 North cites that same letter from Charly’s counsel as the basis for its statement that Margate does not have a registered service agent. See Mot. at 3 (citing ECF No. 42). And although 43 North maintains that Alan Rosenberg previously accepted service of the first amended complaint on behalf of Margate at the 21900 Neuralia Road address, see ECF No. 59,11 and that 43 North made “multiple unsuccessful service attempts” at that address, “notably even making contact with Mr. Rosenberg who refused to accept service,” Mot. at 3, the proof of diligence from the process server states that the attempted service on the occasion that the process server spoke with Rosenberg was only an attempt to serve Ficara. See Mot. Ex. 2 (attempted service on October 17, 2024, when “server spoke to Alan Doe”). Yet despite these issues, “[i]mpracticability does not require satisfying due diligence, or even showing that actual prior attempts to serve a party under each and every method provided in the statute have been undertaken.” Freeman v. Giuliani, No. 24-mc-353 (LJL), No. 24-cv-6563 (LJL), 2024 WL 5054913, at *2 (S.D.N.Y. Dec. 10. 2024) (quotation marks omitted). 43 North’s attempts at service at Margate’s registered Pennsylvania address demonstrate the impracticability of service on Margate by traditional means. Moreover, as noted above, “[s]ervice by alternative means is all the more reasonable where a defendant demonstrably already has knowledge of the lawsuit.” Marvici, 2021 WL 5323748, at *5. Since Margate already has been served with the first amended complaint, it demonstrably has knowledge of the lawsuit. Accordingly, the Court finds that service on Margate by alternative means is appropriate. 43 North requests permission to effect service upon Margate by (1) certified mail sent to its address of registration at 108A Erickson Avenue, Essington, PA 19029, and (2) email sent to [email protected]. See Mot. at 5; Levin Decl. 12 & n. 1. While the 108A Erickson Avenue address is currently listed as Margate’s address of record according to the Pennsylvania Department of State, and its LLC registration is listed as active, see Levin Decl. Ex. 6, there is no evidence that Margate is actually at that address. The Court nonetheless approves alternative service by certified mail sent to that address since, similar to the proposed alternative service on Ficara, it is proposed in tandem with alternative service by email. See Marvici, 2021 WL 5323748, at *3-4 (where plaintiffs knew that defendant did not actually live or work at the addresses at which they proposed to serve him by certified mail, court found that due process was satisfied where plaintiffs intended to “supplement the mailings with service via text message,” noting that courts “have approved multi-prong approaches to service”). As noted above, 43 North’s counsel sent an email to [email protected], the email address provided on the “Contact Us” webpage of Margate’s website, on December 5, 2024, and did not receive a bounce-back or mailer daemon notice. Levin Decl. 14. Accordingly, service by email sent to [email protected] is reasonably calculated to provide Margate with notice of the crossclaims. See Toyo Tire & Rubber Co., Ltd., 2016 WL 1251008, at *3 (C.D. Cal. Mar. 25, 2016); see also Fusa Franchisor SPV, 2023 WL 8125854, at *2. Furthermore, since Rosenberg accepted service of the first amended complaint on behalf of Margate just over four months ago, he is undoubtedly on notice of the lawsuit, and it is reasonable to infer that he remains authorized to accept service on behalf of the LLC. 43 North has established that the [email protected] email addresses is undisputedly connected to Margate, that service to this email address is likely to reach Rosenberg, and that such service is reasonably calculated to provide Margate with notice of the crossclaims. The Court therefore approves alternative service by this method as well. C. Extension of Time to Effect Service of the Summons and Crossclaims 43 North requests that the period to effect service on the Crossclaim Defendants be extended nunc pro tunc to a date 60 days from the date of this order. See Mot. at 4. Rule 4(m) of the Federal Rules of Civil Procedure provides that “[i]f a defendant is not served within 90 days after the complaint is filed, the court — on motion or on its own after notice to the plaintiff — must dismiss the action without prejudice against that defendant or order that service be made within a specified time”; however, “if the plaintiff shows good cause for the failure, the court must extend the time for service for an appropriate period.” Fed. R. Civ. P. 4(m). 43 North has made numerous unsuccessful attempts to effect service on the Crossclaim Defendants using traditional methods at multiple addresses. The Court finds that 43 North has demonstrated “good cause” for its failure to effect service within the 90-day period provided by Rule 4(m), and that an extension of time is therefore warranted. See Wells Fargo Bank, N.A., 2021 WL 9678391, at *3 (finding good cause under Rule 4(m) and granting extension of time to effect service). In light of the approved methods of alternative service, however, the requested 60-day extension is not necessary. A 14-day extension from the date of this order is more than sufficient to effect service by certified mail and email. See, e.g., Marvici, 2021 WL 5323748, at *5 (granting 19-day extension of time). D. Service of 43 North’s Discovery Demands Given the Court’s findings regarding the impracticability of serving Ficara and Margate, there is no reason to believe that 43 North will have any greater likelihood of being able to serve notices of, or subpoenas for, depositions, requests for production of documents, and interrogatories by traditional means. Accordingly, the Court authorizes 43 North to serve Ficara and Margate with notices of, or subpoenas for, depositions,12 initial requests for production of documents, and initial sets of interrogatories via the same alternative means, and at the same time, that it serves the summonses and crossclaims. In addition, to obviate the need for separate, and likely futile, efforts by Charly to serve any discovery demands on Ficara and Margate,13 to be followed by a new motion to authorize alternative service, and all of the delay that would necessarily result from such efforts, any discovery demands that Charly wishes to formally serve on Ficara and Margate also must be served by 43 North at the same time, and via the same means, as the service of the summonses and crossclaims and service of 43 North’s discovery demands. Charly must provide any new or additional notices of, or subpoenas for, depositions, requests for production of documents, and sets of interrogatories for Ficara and Margate to counsel for 43 North by no later than Friday, January 10, 2025, so that these materials can be included in the service package.14 CONCLUSION For the foregoing reasons, 43 North’s motion to authorize service of its crossclaims by alternative means, and to extend the deadline to complete service of the crossclaims, ECF No. 68, is GRANTED. 43 North may effect service on Ficara by (1) certified mail sent to 21900 Neuralia Road, California City, California 93505, and (2) email sent to [email protected] and [email protected]. 43 North may effect service on Margate by (1) certified mail sent to 108A Erickson Avenue, Essington, PA 19029, and (2) email sent to [email protected]. The deadline to complete the authorized service on the Crossclaim Defendants and to file proof of service on the docket is extended to January 13, 2025. In addition, 43 North’s motion, ECF No. 76, to serve its discovery demands on Ficara and Margate by the same alternative means is also GRANTED. Service of both 43 North’s discovery demands and Charly’s discovery demands (if any) on Ficara and Margate must be made at the same time as the service of the summonses and crossclaims. To facilitate this, Charly must provide any new or additional discovery demands to be served on Ficara and Margate to counsel for 43 North by Friday, January 10, 2025, or notify counsel for 43 North by that date that it does not intend to serve any new or additional discovery demands. SO ORDERED. Dated: December 30, 2024
