Do I get half of my wifes inheritents if she files for divorce

If your Wife has received an inheritance in her name and she kept it separate from any community accounts, then it is likely she keeps 100% of her inheritance.  The value of that inheritance, however, may be a consideration if spousal maintenance (alimony) will be an issue in a divorce.  If the amount is significant, it may show she is sufficient financial resources and does not need spousal maintenance or does not need a significant amount of spousal maintenance. If she has used her inheritance for joint property purchases such as a house or investment account, she typically can not get that back under a strict reading of the law.  It will likely be considered a gift to the community.  See A.R.S. 25-211(A).  The above is a general answer.  You are advised to get a consult to make sure of how the law applies to your specific situation.
