There is no way she is entitled to 10% of his money much less half. I don't know the private details of what caused the marriage to break up and neither do you. As his wife of many years she should receive enough to live comfortably but there is no way she should receive hundreds of millions. I don't care what slimy divorce lawyers say.
Men who work hard all their lives and are successful always have someone trying to take their money.
If it was a 5 year marriage I'd agree with you .... 30 something years ... yeah .. HALF.
Ummm....scroll on up to reply 20 and meet the private detail that caused the marriage to break up.
Well, since you admit you don't know what caused the marriage to break up, then you must admit that it is possible that Mr. Gibson is an immoral womanizer and that he humiliated Mrs. Gibson while desecrating his marriage.
Since you admit that, then you must admit that maybe Mrs. Gibson is entitled to her half of the accumulated assets.
Fortunately for Mrs. Gibson, your opinion of the situation matters not. She is going to get in excess of $400 million dollars in the divorce settlement.
