It's really too much to ask of anyone. (with a lot of legal advice and planning) If it were me, I would leak enough of the settlement details, until it pisses off the WT. Wait until they take me to court. Put the whole case and settlement online. The WT would have to provide a copy of the settlement to the Judge as evidence. Lawyers get to question both sides - now into public record.
Find a way to loose/hide the settlement money. I would claim to have put it all into KH box donations. I guess they don't keep track. Ha - subpena all their accounting records to prove it.
If I loose and I am ordered to repay the money - file for bankruptcy. Off the hook. (this is the reverse of how little people can get back at big corps).
Wait for the dust settle while I write a book about the whole experience. Sexual abuses. The cult. Include all the public records and transcripts and a full copy of the settlement agreement.
They can't take you to court for the same thing twice as it has already been ruled upon.
Retire on the royalties.
I would be pleased to see a complete expose book in my local book store. Probably a lot of sales to the Protestant and Catholic too, perhaps just out of curiosity. It would be great exposure.
Non-disclosure court settlements invariably start "with no admission of guilt ... we will payout 5 million" Uh huh. By the WT paying out, it validates the whole case.
