Matters That Can Be Provided for by Will

The Civil Code and other laws contain the following provisions on testamentary matters that can be provided for by will. Matters other than the following (for example, a message to the heirs, or the decedent's wishes regarding the funeral or the interment of ashes) can also be written as supplementary remarks.
Key Distinction
| Testamentary matters | legally effective |
|---|---|
| Supplementary remarks | not legally binding, but they convey a strong message to the heirs |
If this distinction is confused, the result is a will in which "the wishes were conveyed, but nothing has been legally decided."

- ① Recognition of a child (Civil Code Art. 781(2))
- ② Designation of a guardian of a minor and a supervisor of guardianship (Civil Code Arts. 839 and 848)

- ④ Designation of a successor to ancestral rites (Civil Code Art. 897)
- ⑤ Designation of inheritance shares, etc. (Civil Code Art. 902)
- ⑥ Expression of intent to exempt a gift from collation (amended Civil Code Art. 903(2))

- ⑮ Change of the insurance beneficiary (Insurance Act Arts. 44 and 73)
Testamentary Matters in the Narrow Sense (Matters That Can Be Provided for Only by Will)
Among these, ②, ⑤, ⑦, ⑧, ⑨, ⑩, and ⑫ are called "testamentary matters in the narrow sense" and can be provided for only by will.
As discussed in another article, testamentary matters must clearly state the scope of the property they cover and the method of division, etc., so that doubts do not later arise over their interpretation. When preparing a will, therefore, please consult a lawyer or other professional and seek advice.
Practical Points
These matters have no legal effect if done by:
- Contracts made during one's lifetime
- Verbal promises
- Memoranda
or the like.
These are extremely important matters that become legally effective only when made in the form of a will.
Each Testamentary Matter (Selected Commentary)
Designation of inheritance shares (⑤)
The estate can be divided in shares different from the statutory shares.
Example: "one half to the wife, one quarter to the eldest son, and one quarter to the eldest daughter."
As a point of caution, if the disposition infringes the legally reserved share, it becomes subject to a claim for the amount of infringement of the legally reserved share.
Designation of the method of partition and prohibition of partition (⑦)
You can even specify which heir is to acquire which real estate or bank deposits.
It is also possible to prohibit the partition of the estate for up to five years.
In practice, this is often used in cases such as "I do not want the house to be sold while my spouse is alive."
Universal and specific bequests (⑨)
Property can also be given by will to persons other than the heirs (a common-law spouse, nephews and nieces, third parties, corporations, etc.).
A common-law spouse has no statutory right of inheritance at all, so if no will is written, he or she may be unable to acquire a single yen.
Designation of an executor of the will (⑩)
You can designate a "person in charge of the procedures" for carrying out the contents of the will.
If a dispute among the heirs is anticipated, it is safer to designate a third party (a lawyer). In wills that do not designate an executor, disputes often become protracted after the inheritance opens over the question of "who is to handle the procedures."
Supplementary Remarks (Not Legally Binding, but Important Messages)
Words of gratitude to the heirs, the reasons for the division of the estate, words of appreciation for their caregiving, hopes for the future, and the like can be written in a will as supplementary remarks.
Although they have no legal effect, they have a great influence on the heirs emotionally and are often extremely effective in preventing disputes. Wills with carefully written supplementary remarks quite often result in "a marked reduction in disputes over the division of the estate" or "the withdrawal of a claim based on the legally reserved share."
Summary

The matters that can be provided for by will are:
- designation of inheritance shares
- how the estate is to be divided
- bequests to persons other than the heirs
- designation of a guardian and an executor of the will
- succession to ancestral rites, the spouse's right of residence, and the creation of trusts, etc.
The scope is very wide, and it is possible to create a blueprint for the entire succession.
A will, as part of end-of-life planning, is
- "how to divide the property"
- "feelings toward the family"
- "prevention of future disputes"
— the final and most important legal document of one's life, by which all of these can be realized at the same time.
Before preparing one on your own, we strongly recommend that you always have it checked by a professional at least once.
If you are in the Yaizu, Yoshida-cho, Makinohara, Fujieda, or Ohmaezaki area and have questions such as "What should I write in my will?" or "Is this content legally effective?", please feel free to consult the Yaizu Sogo Law Office — whether before creating your will or for confirmation after creating it.
Frequently Asked Questions
Can a will include matters other than how property is divided?
Yes. A wide range of matters can be provided for, such as the designation of a guardian, the designation of a successor to ancestral rites, and the designation of an executor of the will.
Can the method of the funeral or the place of interment be specified in a will?
It can be stated as a supplementary remark, but it has no legally binding force.
Can I leave property to a common-law spouse?
Yes, by bequest in a will. Without a will, as a rule, the spouse cannot acquire anything.
Does everything written in a will always have legal effect?
No. It has no legal effect unless it is a "testamentary matter" recognized by law.
Can I write a will that reduces the legally reserved share to zero?
It can be written in a will, but you may face a claim for the amount of infringement of the legally reserved share.
Who should I consult about the contents of testamentary matters?
It is safest to consult a lawyer or other professional. Deciding on your own involves great risk.
