How grandchildren, nephews, and nieces take the baton through "Substituted Inheritance"
When proceeding with inheritance procedures, you may encounter a situation where "the person who was supposed to be the heir has already passed away." In such cases, a system called "Substituted Inheritance" (daishu sozoku) comes into play.
In this article, we will explain this mechanism of passing down assets across generations in a way that anyone can understand.
1. What is Substituted Inheritance?
Substituted Inheritance is a system where, if the person who was originally supposed to be the heir (a child or sibling) has passed away before the decedent (the person who died), their children inherit the right to inherit in their place.
For example, if a father (the child) passes away before his grandfather (the decedent), the grandfather's assets will be directly inherited by the father's children, the "grandchildren." This is the typical pattern of substituted inheritance.
2. Who can be a "substitute"?
Substituted inheritance is limited to the following two cases:
① When a child has passed away first (1st priority)
* Grandchildren become the substituted heirs.
* If the grandchildren have also passed away, it is passed down to their children, the great-grandchildren (re-substitution). As long as the child's lineage continues, it will be passed down to the next generation.
② When a sibling has passed away first (3rd priority)
* If the deceased has no children or parents, the siblings become the heirs, but if those siblings have passed away first, their nephews and nieces become the substituted heirs.
* Note!: Substitution for siblings is limited to one generation of nephews and nieces. It is not passed down to the children of nephews and nieces.
3. When does "substitution" occur? (3 causes)
Substituted inheritance does not only occur when the original heir has passed away. The law specifies the following three main cases:
* Death: The original heir passed away before (or at the same time as) the decedent.
* Inheritance disqualification: The person legally lost their rights due to committing a serious crime, such as forging a will or murder.
* Disinheritance of an heir: The person was stripped of their rights by the decedent's petition due to abuse or serious insults.
* However, if an heir "renounces their inheritance," their children cannot inherit through substitution.
4. Complex cases: What about "stepchildren" or "common-law partners"?
Substituted inheritance is based solely on "blood ties (or legal parent-child relationships)."
* Stepchildren: Unless there is a legal adoption, substituted inheritance does not occur for the stepchildren of a remarried spouse.
* Children of a common-law partner: Unless they have been legally acknowledged, they have no inheritance rights, and no substitution occurs.
5. How is the "share" of a substituted heir determined?
A substituted heir inherits the exact "share that the person who originally passed away was supposed to receive."
For example, if there are two children (eldest son and second son), the eldest son has passed away first, and the eldest son has two children (Grandchild A and Grandchild B):
* Second son: 1/2
* Grandchild A: 1/4 (the eldest son's share divided equally)
* Grandchild B: 1/4 (the eldest son's share divided equally)
Even if the number of people increases, the rule is to divide it within the original "share per family line."
Summary: Check your family tree to know "who will inherit"
When substituted inheritance occurs, the number of heirs may increase unexpectedly, or estranged nephews and nieces may join the discussions.
* If there are children, it goes to grandchildren (and continues to great-grandchildren)
* If there are siblings, it goes to nephews and nieces (and ends there)
Understanding this principle and grasping who will take the baton in your own family structure is the first step toward a peaceful inheritance.
