No divorce is easy, but high-asset couples have more property, and more complex types of property than other couples, making their divorces more complicated. Few couples in the world have more assets than Jeff and MacKenzie Bezos.
Prenuptial agreements can make decisions in advance about many issues, but they used most often to decide questions of property division. This is also the case in postnuptial agreements, which are signed after the couple has already been married. Rather than dividing the community property according to the dictates of Texas law, the married couple gets to decide in advance how to divide their assets through an agreement they signed before the divorce.
