If your wife suspects your screwing her over, she will get attorneys working double time to track everything down. And you know who pays for her attorneys as they work to find your money- you do! actually, she can get her attorney fees paid out of the “marital estate” since thats her only source of wealth until the finances are sepearated in the divorce.
And there are those declarations about your wealth that you need to make under the penalty of purjury. The judge will not look on you kindly if you lied on those!
So think twice before you adopt this stratagy. A quick negotiated settlement is the best way to go 99% of the time.
