Thanks for writing back -- good to hear from you.
I will be glad to comment further -- please see below.
Before I address your inquiry, however, I want to take a moment and say a heartfelt thank for your payment, generous bonus, and most of all kind words -- all greatly appreciated!
Now, on to your most recent post. You are absolutely right about some of the recent controversies surrounding private process servers -- especially in the State of New York. Obtaining personal jurisdiction is such a foundational matter. Without it, the Court can simply not exercise its powers over the Defendant. Yes, the server (who, by the way, has to be license -- I am sure you already knew that point), will have to report back by filing a Return of Service. Generally, for this type of action, service of process has to be completed within 120 days of filing suit. NY CPLR § 306-b. You are indeed correct that both "pinning" (affixing) and mail are required. NY CPLR § 308. The law always favors true personal service -- i.e. literally handing the legal papers to the actual Defendant. The further we get from that ideal (i.e. handing them to an adult at the Defendant's residence) requires more proof that lawful service actually took place.
I hope that helps a bit more. Please feel free to request me again by typing your question in the "Ask Your Question" text box on my Profile Page. In any event, it has truly been a pleasure interacting with you.
Take care and thanks again for choosing JustAnswer®!
