This is the perfect question for your attorney and not DCUM.

You likely have to sue the person who you suspect of hacking in the jurisdiction they reside and then follow the CA rules to get a subpoena for yahoo. In some jurisdictions you need to open a case in that state. But subpoenaing yahoo will not make it a federal case unless the defendant has violated some federal law or there is diversity jurisdiction.

Agreed. If you need a subpoena, you need a lawyer

Start with a Police report in the jurisdiction where you live and go from there.

Hacking.

Good luck.

OP, what is your case? Divorce? Violation of a noncompete clause? Intellectual property infringement?

Because it would move the issue into Federal territory - rather than one between states.

Can you explain why you want this?

Do you suspect them of terror?

I'm looking for email records though -- log ins and ISPs and anything deleted and when.

Typically you would have to sue the person whose email it is and subpoena their email.

How could anyone issue a subpoena to get access to Yahoo email records when Yahoo is located in CA and we are in MD? Any idea how that would work?
