how do you find out who is trying to serve you a subpoena?
There is no way to find out other than to receive the subpoena and see what it says:1) Subpoenas are not served through the court; the court would not have a record;2) The case for which you are being subpoenaed does not have to be in your county--the lawsuit could have been brought in a different county--so checking your county won't necessarily even tell you if there are cases against you (only if there are cases in your country), and if the suboena is for you to be a witness in someone else's case, there is no way to find that with the case name and county.
