It is a fantasy to pretend that Elin and Tiger contribued equally to the marriage in respect of acquiring marital assets. The 50/50 rule is bad law in the case of one spouse with a vastly greater role in acquiring the marital assets.
Marriage is a partnership—don’t you get that?
The law wisely chooses to not quantify the non-monetary value a wife brings to the marriage, it absolutely does not want to get into the business of putting a value on getting and bringing forth of legitimate children.
