[Definitive Guide] Does Ignoring Inheritance Lead to a "Snowball Effect" of Trouble? The Pitfalls of "Successive Inheritance" You Need to Know
"I'm too busy for inheritance procedures right now." "I don't have any particular issues with the title change for my parents' house, so I'll get to it eventually."
Are you putting off inheritance procedures like that? In fact, there is no end to cases where the next inheritance occurs while the previous one is still being ignored. In legal terms, this is called "successive inheritance" (suuji souzoku).
In this article, I will explain in simple terms for the general public what happens when successive inheritance occurs, and the difference between it and "substitutional inheritance," which is often confused with it.
1. The Terror of "Successive Inheritance" Where Inheritances Overlap
Simply put, successive inheritance is "when one of the heirs passes away before the inheritance procedures are completed."
For example, suppose a husband passes away in a childless marriage, and the wife and the husband's siblings become the heirs. While they are in the middle of inheritance division discussions (negotiations), the wife also passes away... This is successive inheritance. In this case, the siblings (nephews/nieces) who become the wife's heirs also become parties to the inheritance division discussions for the husband's estate as successors to the deceased wife's rights and obligations.
Why does ignoring it lead to a "snowball effect" of trouble?
If an inheritance only occurs once, the parties involved are often just a few family members. However, when successive inheritance occurs, the rights of the deceased heir are further inherited by their family (spouse, children, etc.).
While you put it off for years or even decades saying "I'll do it eventually," the generations of relatives change. As a result, it is not uncommon for the number of heirs, which was initially three, to grow to "over 10 people, including cousins and nephews/nieces you have never even met."
The more people involved, the more the following barriers stand in your way:
Cannot get in touch: Just finding the current addresses of estranged relatives is a struggle.
Discussions cannot be settled: It is an extremely difficult task for people with distant relationships to decide how to divide the estate (especially real estate that is hard to convert into money).
Documents cannot be collected: A seal registration certificate is required from everyone, and if even one person does not cooperate, the procedure stops.
2. How is it different from "substitutional inheritance"?
There is a term often confused with successive inheritance called "substitutional inheritance" (daishu souzoku). Because both have the image of "children inheriting instead," they are easily confused, but they are actually completely different things.
○ Substitutional Inheritance (when they have passed away beforehand)
Chronology: A case where the heir (child, etc.) passed away "before" the decedent (the person who died).
Who inherits?: The child of the deceased child (grandchild) inherits the rights specifically.Spouses are not included.
○ Successive Inheritance (when they pass away afterwards)
Chronology: A case where the heir passed away "after" the decedent.
Who inherits?: "All heirs" of the deceased heir inherit. Since this includes the spouse, the number of people involved expands horizontally all at once.
3. A Prescription for Preventing "Successive Inheritance"
Even if you think, 'We're fine because our family gets along well,' you cannot control human lifespans. To avoid getting lost in the complex maze of successive inheritance, the following two points are ironclad rules.
1. Don't leave it unattended just because 'it's not a problem right now'
Changing the name on real estate (inheritance registration) became mandatory in April 2024. However, it is important to organize titles early, not just because it is mandatory, but to 'avoid burdening your future family.'
2. Write a will
If you have a will, there are many cases where you won't need to get everyone's seal on an 'inheritance division agreement' in the first place. A will acts as a 'breakwater' that protects your surviving family from the chaos of successive inheritance.
4. Summary: 'Freshness' is vital for inheritance
In inheritance procedures, time is not on your side. As time passes, the number of involved parties increases, memories fade, and the difficulty of the procedures rises.
'Successive inheritance' is by no means a story limited to special families. Change 'it's still okay' to 'do it while you can.' If you are already in a situation where the number of heirs has increased and you don't know where to start, begin by asking a professional to collect family registers and organize the relationship chart.
Taking that first step leads to protecting the bonds of your precious family.
