I've seen some of your threads. You don't seem to be able to see the overall picture.
My advice.
Bring the whole lot to a head. You file Judicial Separation proceedings.
Sort them out.
Get your result
Ask the Judge to refer the Fraud matters to the DPP.
Send your papers to Revenue. If you seriously think that won't come straight back to your door.
But more than anything else, please get a solicitor. Your posts on here have been very fractured and you need real direction from a legal person, on your specific circumstances.
