After divorce, the wife may not inherit the estate of her ex husband, unless the ex husband has a will to leave it to his ex wife. Once the couple divorced, there would be no legal relationship, nor the spouse relationship in the Civil Code. Therefore, the ex wife is not the legal heir of the ex husband, and has no right to inherit the estate of the ex husband.
