No, that isn't what a 50/50 split means at all. It only applies to assets acquired during the actual term of the marriage, for starters. You don't get a permanent lien on someone's parents' or another country's crown assets because you married someone in that family.
Divorce Laws in California (2021 Guide) | Survive Divorce
"California divorce laws allow for spouses to agree on dividing some assets but seek a ruling on other assets, such as how to decide how each person’s interest in a residence is decided. In addition, every asset does not need to be divided equally down the middle. As long as there is give and take that results in the overall assets being divided in a fair way, then the court will probably approve the asset division plan.
Asset division not only includes real property, it also includes financial holdings as well. Bank accounts, stocks,
IRAs and 401Ks are treat just like real property.
The biggest stumbling block when it comes to a division of assets is when one spouse or the other claims that the asset or assets in question are not actually community property, but instead are separate property. Separate property is defined as an asset that was acquired before a couple was married or acquired after the date of separation.
There can also be questions and challenges when one spouse receives an inheritance, which is considered separate property, but then proceeds to commingle it with community property assets. For example, if a spouse receives a lump sum of cash and deposits it into a joint bank account, this could be considered commingling."
Debts and Assets:
"California is a community property state which means that any debts or assets acquired by one or the other spouse during a marriage belong equally to both spouses.
The exception to this is that when spouses are discussing a division of assets during the divorce proceeding, one spouse or the other may agree to assume the debt in question in exchange for other concessions. In cases where there is excessive debt above and beyond a couple’s community assets, courts may assign a greater portion of the debts to the spouse who is in better financial condition to pay off the debts."
Property:
"California is a community property state. Under the California Family Code, this generally means that all property, real or personal, that was acquired by either party during a marriage is equally owned by each partner.
However, there are exceptions. For example, if the property is acquired during the marriage by way of inheritance or a gift, then the person who was given that property retains sole interest in it. Also, any property that was acquired either before the marriage or after the date of separation of the marriage is considered the sole property of the person who acquired it."
Gifts:
"California law states that gifts given to one spouse by the other during a marriage are considered separate property. For example, if a wife received a $10,000 diamond watch as a birthday gift, those would clearly be hers in a divorce action.
However, there are other instances that can lead to disagreements when the intent is less clear that the property was actually a gift. If a husband buys a wife a new car for Christmas, but it is intended for both to use as part of their life together, things can become murky as to whether or not it was a gift or it was community property.
Gifts to either spouse by a third party are generally considered separate property. "
