"Community property means that all income earned within the marriage is owned equally by the spouses, and all property bought with CP funds is also CP. There is a presumption that property owned by a married person is CP, but that can be overcome by a showing that it was owned before the marriage, or given to a spouse by someone as their separate property (like an inheritance).When a married person dies without a will, their property (which is a 1/2 interest in their community property) passes to their heirs. When a married person dies childless, their only heir is their spouse, and all the CP would therefore pass to the spouse.
If Scott becomes ineligible to inherit from Laci because he is proven to have killed her, then the succession would go to Laci's parents, then her siblings, and then you get into cousins, uncles, etc."
