Guys - after a long long think and a discussion with my C, I took a decision to do something I'm not proud of.
The company "after" my W has said that withholding information could lead to an offense and prosecution. They also stated that they would find her through their tracing agency. I'm not trying to justify my actions. Just passing on the conversation.
My C agreed. He also asked my why I felt the need to protect my W from the world. She's a grown woman. Stop trying to fix things. Where the heck have I heard that before.
I wish my W had discussed this problem with me in February when I spent 2 solid weeks sorting my cr@p out. This would have been just another one to add to the pile, negotiate, pay each month and move on.
