Over 15,000 Estate Disputes a Year — Why Real Estate Causes Conflict
"Our family won't fight over inheritance because we have few assets" — in fact, estate-division disputes are by no means only a problem for the wealthy. We explain the reality shown by judicial statistics, why real estate tends to cause conflict, and the preparations you can make now.

01The reality of estate-division disputes
Estate-division cases handled by family courts exceed 15,000 a year. And what stands out is that many are not disputes over "large fortunes". Cases where the total estate is several tens of millions of yen or less make up a considerable share.
02Why real estate tends to cause conflict
Unlike deposits, real estate is hard to "cleanly divide by the number of people". The following traits tend to breed disputes.
- Physically hard to divide (you can't halve a home)
- Multiple ways to think about the valuation, so people clash over what value to assume
- Opinions split over whether to sell or keep living there
- Joint ownership leads to renewed disputes later over selling or use
03Three ways to handle "hard-to-divide assets"
| Method | What it is | Points to note |
|---|---|---|
| Compensatory division | One person takes the property and pays money to the other heirs | The taker needs funds to pay |
| Conversion division | Sell, convert to cash and divide | Sale effort; transfer tax may apply |
| In-kind division | Each takes assets as they are | Real estate is hard to split and tends to end up jointly owned |
04What you can do now to prevent disputes
- Make a will that clearly sets out who inherits what
- Discuss the valuation and division approach for real estate with family early
- Consider life insurance as funds for a compensatory division
- With a specialist, simulate a division plan that includes taxes
Inheritance can turn into "inheritance strife", but lifetime preparation prevents many disputes. If you own real estate, we recommend acting early.
Summary
Estate-division disputes exceed 15,000 a year and occur even in households with few assets.
The more an inheritance centers on hard-to-divide real estate, the harder it is to divide fairly and the more prone to conflict.
Knowing options like compensatory and conversion division, and preparing early with a will and life insurance, is effective.
