I found a cd of my wife talking to a "psychic" having her tarot cards read and she's talkung about being obsessed with a guy who I believe she tricked me into moving to sydney so she could be with. Is this admissible in court?
It depends on which court.
And on what sort of proceeding.
And on what you are trying to prove by it.
As a general rule, material that a party wants to use as evidence needs to be
(i) Relevant to the question being decided
(ii) Reliable
(iii) Logically probative of what it's being used as proof of.
(iii) Preferably, lawfully obtained.
