In Most Community Property States, inherited property acquired after Marriage is not considered a Community Asset. Inherited Property is Separate Property of the Spouse receiving the Inheritance.
If Inherited money has been used as a Down payment on a House taken in joint names; or to Purchase another asset or even mixed with Community Funds in a Bank Account, it is possible to have that Separate Property Reimbursed at Divorce, provided it can be "traced." In other words, provided the owner of the Separate Property Inheritance can prove that the funds came from their inherited money.
