Quoting AlwaysOnTime I said that I know of no such requirement in NYC when it's just a mere information subpoena (Q&A, no restraint). I just showed you the requirement. A subpoena is a subpoena. The Rule doesn't make the distinction that you desire it to. What do you think asking for information is doing? You serve it on the bank, you serve it on the judgment debtor.
Thank you Jack!
