Not to hijack, but I have recordings of my W giving great detail about her infidelity. How do I use this as evidence? I can't expose how I know what I know if it's illegal. Right?
Sorry to hijack.
You'd have to ask your attorney. The laws about recording are different by state; some are "one-party" states and some are "two-party," and some are altogether different.
In my state (FL), my atty told me they were inadmissible, but I CERTAINLY was able to use them to:
a) gather useful intel;
b) help me make a determination about whether or not I should go for primary custody of our sons;
c) bluff my wife, and get her to "come clean" and start telling the truth to our adult daughters, and to her parents, and to ME, and to stop throwing me under the bus to these people.
