From what I've found on the Internet it appears there is a Federal law that spouses have a right to email privacy, is this correct and can anyone add an overview about the major portions of it, thank you.
We need more information. There are laws that prevent hacking into accounts and laws that prevent intercepting communications in transit. However, there is little likelihood of prosecuting a spouse who shares a computer and looks at files.
If you can provide some more facts, I might be able to point you to the laws that you seek.
