Whether the parents' inheritance belongs to the joint property of husband and wife depends on the specific circumstances.
If parents have determined in their wills that the estate belongs only to one of the husband and wife, then the estate does not belong to the joint property of the husband and wife. However, if it is not determined in the will that only one party belongs to the husband and wife, then it is the joint property of the husband and wife.
