The problem with a pre-nup is the stupid divorce court is out of control. They can and regularly do, ignore them.
The best asset protection policy is the one that she doesn’t know about (relying on financial privacy for protection) and that takes disputes outside of the rogue divorce court.
Hiring a divorce attorney before you get married to discuss all the nasty things that can happen during a divorce is a solid investment in your future. As is hiring a specialist in this type of protection to counsel you on what actually works and what doesn’t.
However, my own opinion is…..
simply refuse to get married. she'd probably want a divorce though stats say women file for divorces like 4 times more then men
