Is life-insurance money subject to estate division, and is it brought back into hotchpot as a special benefit?

In short: life-insurance money (death benefit) with a named beneficiary is, as a rule, property the beneficiary receives as their own right, and it is not included in the estate to be divided in an estate division. However, where the unfairness between the beneficiary heir and the other heirs is so markedly excessive that it cannot be endorsed in light of the purpose of Article 903 of the Civil Code, exceptionally it may become subject to hotchpot in a manner analogous to a special benefit—this is the Supreme Court's approach (Supreme Court decision of 29 October 2004). This article is general information organising the rule and the exception; the application to amounts and judgements on tax or disputes are made by qualified professionals.

Is life-insurance money part of the property divided in an estate division?

As a rule, it is not. The inherited property (estate) is the property the deceased held at the time of death. By contrast, a death benefit with a named beneficiary is money the beneficiary receives directly from the insurer under the insurance contract, conditional on the deceased's death. Because it is not inherited from the deceased but acquired by the beneficiary as their own right, as a rule it is not subject to division in the estate-division agreement.

So, even if there is "a death benefit of 20 million yen with the eldest son as beneficiary," that 20 million yen is the son's own property and, as a rule, does not come onto the table of the estate-division discussion. Estate division is the procedure in which all the heirs decide who acquires what of the deceased's own property—deposits, real estate, securities and so on. The way to draw up an estate-division agreement is organised in Can you draw up an estate-division agreement yourself?.

Item	Subject to estate division?
Deposits, real estate and securities in the deceased's name	Yes (inherited property)
A death benefit with a named beneficiary	As a rule no (the beneficiary's own property)
A death benefit whose beneficiary is designated only as "the heirs"	As a rule no (each heir acquires it as their own right)
A contract with the deceased themselves as beneficiary (goes into the estate)	Yes (included in the inherited property)

The policyholder decides who the beneficiary is. The policyholder may change the beneficiary until the insured event occurs (the deceased's death) (Insurance Act, Article 43) and may also change it by will (Insurance Act, Article 44). If the beneficiary died before the deceased, all of that beneficiary's heirs become the beneficiaries (Insurance Act, Article 46).

Why is insurance money with a named beneficiary the beneficiary's own property?

As to the claim to a death benefit under an endowment insurance contract, the Supreme Court has held that "the insurance beneficiary acquires it as their own inherent right, not by succession from the policyholder or the insured, and it does not belong to the inherited property of those persons" (Supreme Court decision of 29 October 2004, Minshu Vol. 58, No. 7, p. 1979). As long as a beneficiary is named, the insurance money is money that passes to the beneficiary as an effect of the contract, not money that once becomes the deceased's property and then moves by inheritance.

This is a point often misunderstood in estate division. Even if an heir thinks "the insurance money is also the estate, so it should be split equally," as a rule that argument does not prevail. Conversely, from the standpoint of the heir who is the beneficiary, the insurance money is their own property, and as a rule they have no duty to share it with the other heirs. First grasp this rule, then confirm the following exception.

When does it become subject to hotchpot in a manner analogous to a special benefit?

Article 903, paragraph 1 of the Civil Code provides that where, among the co-heirs, there is a person who received from the deceased a bequest, or a gift for marriage, adoption or as capital for livelihood, that portion is brought back into the calculation as an advance on the inheritance share (a special benefit). A death benefit does not formally fall under this "gift or bequest," so as a rule it is outside hotchpot.

The Supreme Court decision cited above, however, recognised an exception. It held that "where there is a special circumstance to be evaluated as making the unfairness arising between the heir who is the insurance beneficiary and the other co-heirs so markedly excessive that it cannot be endorsed in light of the purpose of Article 903 of the Civil Code, the death-benefit claim becomes, by analogy to that Article, subject to hotchpot in a manner analogous to a special benefit." It then held that the presence of a special circumstance should be judged by comprehensively considering circumstances such as the following.

Main circumstances considered
The amount of the insurance money
The ratio of that amount to the total estate
Whether the beneficiary heir lived with the deceased
The degree of contribution to the deceased's care, etc.
Each heir's relationship with the deceased and their living situation

What matters is that a large amount alone does not automatically result in hotchpot, and there is no uniform standard such as "over a certain percentage of the estate means hotchpot." In actual case law, too, the conclusions differ from case to case. Whether a case amounts to "markedly excessive unfairness" is an individual judgement with a dispute element, so it is made by an attorney. For the general theory of special benefits, see The basics of special benefits and contributions; for the relation with the legally reserved portion, see also The basics of the legally reserved portion.

How does the tax-exempt allowance differ from the treatment in estate division?

"Whether it is subject to division in the estate" (a Civil Code question) and "whether inheritance tax applies" (a tax-law question) are separate matters. In estate division, a death benefit is, as a rule, the beneficiary's own property; but in the world of inheritance tax it is included in the taxable base as "deemed inherited property." However, where the beneficiary is an heir, up to "5 million yen × the number of statutory heirs" is tax-exempt under Article 12, paragraph 1, item 5 of the Inheritance Tax Act.

Issue	Civil Code (estate division)	Inheritance Tax Act (taxation)
Position of the death benefit	As a rule the beneficiary's own property (not subject)	Deemed inherited property (taxable)
Tax-exempt allowance	—	5 million yen × number of statutory heirs
Where a person who renounced inheritance receives it	Own property (not subject)	May receive it, but cannot use the tax-exempt allowance

The "number of statutory heirs" used to calculate the allowance is counted as if any renunciation of inheritance had not happened, even if someone renounced. Where the statutory heirs include adopted children, there is a cap on how many adoptees are counted: up to one where there is a natural child, and up to two where there is none. Where a person other than an heir (for example a grandchild or a cousin) is the beneficiary, the allowance does not apply. Whether inheritance tax is required at all is determined in relation to the basic exemption (Is an inheritance-tax filing required?). The final judgement on calculating the tax and whether a filing is required is made by a tax accountant, the tax specialist.

If there is a dispute over the treatment of the insurance money, who do you consult?

An inheritance problem over life-insurance money crosses the Civil Code, tax law and insurance practice, so the roles are divided. An administrative scrivener can support drawing up the estate-division agreement that decides how the inherited property itself is divided, and collecting the family registers that identify the heirs. On the other hand, an individual judgement disputed among the heirs—such as whether the insurance money is brought into hotchpot in a manner analogous to a special benefit—is the domain of an attorney.

FAQ

Q. There is life-insurance money with only my elder brother as beneficiary. Can I have it shared with me?
A. As a rule it is not subject to sharing. A death benefit with a named beneficiary is the beneficiary's (your brother's) own property and is outside estate division (Supreme Court decision of 29 October 2004). However, where the unfairness from the insurance money is markedly excessive and cannot be endorsed in light of the purpose of Article 903 of the Civil Code, there is a special circumstance under which it may exceptionally be brought into hotchpot in a manner analogous to a special benefit. Whether that applies is a disputed individual judgement, so consult an attorney.

Q. If the insurance money makes up most of the estate, is hotchpot always the result?
A. A large amount or ratio alone does not automatically result in hotchpot. The Supreme Court held that the presence of a special circumstance should be judged by comprehensively considering various circumstances—the amount of the insurance money, its ratio to the total estate, whether the beneficiary lived with the deceased, the degree of contribution to the deceased's care, and so on. There is no uniform standard, and conclusions differ from case to case.

Q. If it is not subject to estate division, is it also free of inheritance tax?
A. That is a separate matter. In estate division a death benefit is, as a rule, not subject; but in inheritance tax it is taxable as "deemed inherited property." If the beneficiary is an heir, up to "5 million yen × the number of statutory heirs" is tax-exempt (Inheritance Tax Act, Article 12, paragraph 1, item 5). The judgement on the tax amount and whether a filing is required is made by a tax accountant.

Q. Even if I renounce inheritance, can I still receive the insurance money?
A. If you are named as the beneficiary, you can receive the insurance money as your own property even if you renounce inheritance. However, the tax-exempt allowance (5 million yen × the number of statutory heirs) does not apply to a person who renounced. A person who renounced is counted in the "number of statutory heirs" that is calculated as if there had been no renunciation, but the insurance money that the renouncing person themselves receives is outside the tax-exempt allowance.
