It doesn't matter what state you live in. If you are divorced & there isn't a will which specifically leaves the divorced spouse something... you don't inherit anything.

Inheritance is separate property under Louisiana law. So it doesn't matter you were married its still separate.

Separate property:

The separate property of a spouse is his exclusively. It comprises: property acquired by a spouse prior to the establishment of a community property regime; property acquired by a spouse with separate things or with separate and community things when the value of the community things is inconsequential in comparison with the value of the separate things used; property acquired by a spouse by inheritance or donation to him individually; damages awarded to a spouse in an action for breach of contract against the other spouse or for the loss sustained as a result of fraud or bad faith in the management of community property by the other spouse; damages or other indemnity awarded to a spouse in connection with the management of his separate property; and things acquired by a spouse as a result of a voluntary partition of the community during the existence of a community property regime. Art. 2341.
