It is clearly defined that legitimate couple have the right of inheriting the heritage of the other. It is a reflection of our civilization development trend and equality between men and women to endow spouse inheritance right. There are some shortcomings in our current laws of spouse inheritance rules, which can be ruled in the legal heir sequence, and perfected from the aspect of setting the legitim system in testamentary succession.
