In many divorces, women are at a significant disadvantage, especially when it comes to money. In many marriages, the husband has been the main breadwinner. He often controls the purse strings, and often knows much more about where money has been spent and what assets are owned.
In contrast, the wife has often had lower earnings, and has had little to no control over the money. She may have been free to spend money as she saw fit, but she did not see the bills, pay the bills, or maintain control over bank and brokerage accounts. At divorce time, she has no idea where the money is, where is may have (improperly) gone, and may have no access to it.
