I read that one can not intercept live or stored electronic messages (phones,ipads,computers, recordings , etc) but then I found this on on this website about the Alienation of Affection part quote ----
Criminal Conversation and Alienation of Affection
A spouse who suspects an affair may spy in order to uncover evidence that could support the filing of a civil lawsuit for criminal conversation or alienation of affection against the spouse’s paramour.
end quote. Is there a law or stature that governs the right to spy under these conditions? If so please provide any further information that you have.
