Who owns the 'rent before estate division' of inherited rental property? Attribution and settlement

In short: The rent that arose before the estate division was settled on an inherited rental property is acquired definitively by each co-heir as a divided sole claim in proportion to their statutory share, and is not affected by the later estate division (Supreme Court judgment of 8 September 2005). So the pre-division rent belongs to each person as per their share and is in principle not settled retroactively afterwards. The drafting of the estate-division agreement goes to an administrative scrivener, inheritance registration to a judicial scrivener, the income-tax return to a tax accountant, rent-allocation or division disputes to a lawyer, and the sale brokerage to us.

This article is for co-heirs who inherited a rental property but whose estate division is not yet settled; it organises the attribution of the "pre-division rent" from the Civil Code, Supreme Court case law, and National Tax Agency materials. What we handle is the valuation of a tenanted property, the arrangement of the sale, and the brokerage of the sale. The drafting of the estate-division agreement goes to an administrative scrivener, inheritance registration to a judicial scrivener, the real-estate-income and quasi-final tax return to a tax accountant, and the allocation of rent or disputes over the division to a lawyer; these are independent entities from Yotsuba Real Estate Co., Ltd. (四葉不動産株式会社), engaged separately for each service under a separation-of-engagement arrangement. For selling while still in co-ownership or selling a share, see consent when selling inherited co-owned property; for selling to divide in cash, see the flow of selling by conversion division.

Who receives the "pre-division rent" of inherited rental property?

The pre-division rent is received by each co-heir in proportion to their statutory share. An heir succeeds, from the time the inheritance begins, to all rights and duties that belonged to the decedent's property (Civil Code Art. 896). Where there are several heirs, the inherited property belongs to their co-ownership (Art. 898), and each co-heir succeeds to the decedent's rights and duties in proportion to their share (Art. 899). The rental property itself is subject to the estate division, but the rent arising from it between the start of the inheritance and the estate division is organised as a separate property from the estate, acquired by each heir in proportion to their share.

Therefore, even if one heir receives and manages all the rent on behalf of the others, in law each heir has acquired it in proportion to their share, so the heir who received it should in principle settle and pass on to the others in proportion to their shares. Who holds the management account, and how expenses such as fixed-asset tax and repair costs are borne out of the rent, are best agreed among the heirs early. Where agreement cannot be reached, a lawyer is involved.

Category	Attribution
The rental property itself	Subject to estate division (co-owned until division)
Rent arising before division	Acquired definitively by each heir in proportion to their share
Rent arising after division	Belongs to the heir who acquired the property

Where the allocation of rent or the sharing of expenses is disputed, a lawyer is involved; once agreement is reached, the drafting of the estate-division agreement is handled by an administrative scrivener.

How did the Supreme Court judge the attribution of this rent?

The Supreme Court judgment of 8 September 2005 (Minshu Vol. 59, No. 7, p. 1931) judged it. The gist is that, because the estate, where there are several heirs, belongs to the co-ownership of the co-heirs between the start of the inheritance and the estate division, the rent claim — a monetary claim arising as a result of using and managing the rental property that is the estate during that period — should be regarded as a separate property from the estate, and each co-heir acquires it definitively as a divided sole claim in proportion to their share.

What matters here is the point "acquires definitively." The rent claim is a divisible claim that attaches to each heir in proportion to their share and does not become subject to the later estate division — that is the position of this precedent. To avoid the inconvenience that, if one heir collects all the rent, the others become unable to collect, the rent claim is understood to be treated as each heir's divided sole claim. The application to a particular case, and whether the heirs can make a separate agreement, are judged by a lawyer.

Point	The Supreme Court's judgment
Nature of pre-division rent	A separate property from the estate
Attribution	Each co-heir acquires it as a divided sole claim in proportion to their share
Definiteness of acquisition	Acquired definitively (unaffected by the later estate division)

The reach of the precedent and its application to a particular case are confirmed by a lawyer, and the drafting of the estate-division agreement that reduces the agreed content to writing is handled by an administrative scrivener.

After the estate division is finished, is the rent settled retroactively?

In principle, it is not settled retroactively. The estate division in principle takes effect retroactively from the time the inheritance began (Civil Code Art. 909 main text; however, it may not prejudice the rights of third parties (its proviso)). Nonetheless, the above Supreme Court judgment of 8 September 2005 holds that the attribution of the pre-division rent claim, which each co-heir acquired definitively in proportion to their share, is not affected by the later estate division. In other words, even if the estate division decides that "a particular heir acquires the rental property," separately from that effect being retroactive as to the rental property itself, the pre-division rent remains fixed as belonging to each heir in proportion to their share.

That said, the heirs may, by the agreement of all of them, decide on an allocation that includes the pre-division rent — this is done in practice in some cases. This is a question of how to divide by agreement among the heirs, separate from the attribution in principle shown by the precedent. Whether an agreement can be reached and how it is put in writing involve a lawyer where there is a dispute, and an administrative scrivener at the stage of putting the agreed content into an agreement.

Scene	Treatment
Retroactive effect of the estate division (Civil Code Art. 909)	Takes effect retroactively from the start of the inheritance (without prejudicing third parties)
Attribution of pre-division rent	Fixed per share, unaffected by the estate division (SC judgment of 8 Sep 2005)
Allocation by agreement of all heirs	Room to decide by agreement, separate from the principle (consult a lawyer / administrative scrivener)

The final judgment on the relation between the retroactive effect and the rent attribution is made by a lawyer, while we assist from the angle of arranging the sale.

Who files the income tax (real-estate income) on the rent?

The rent during the undivided period is, in principle, filed by each heir as real-estate income in proportion to their share. The National Tax Agency's individual-taxation information (published 11 December 2013) states that, until the estate division is settled, the real-estate income arising from the rental property that is undivided estate is attributed to each heir in proportion to their statutory share, and that even if an estate-division agreement is later reached, its effect does not affect the attribution of income during the undivided period. The private-law attribution of rent (SC judgment of 8 Sep 2005) and the tax treatment are thus organised in the same direction.

In practice, even if one heir receives all the rent collectively, each heir in principle apportions and files it by their statutory share. Also, for the year in which the decedent died, the heirs file a quasi-final return of the decedent's real-estate income from 1 January to the date of death (within four months from the day following the day they learned that the inheritance had begun). Who files what range, the allocation of expenses, the treatment of blue returns, and so on vary by case and are confirmed by a tax accountant.

Period	Who files
1 January to the date of death of the decedent's death year	The heirs file a quasi-final return (within four months)
The day after death to the settlement of the estate division	Each heir apportions and files by statutory share
After the estate division is settled	The heir who acquired the property files

The real-estate-income and quasi-final tax return are handled by a tax accountant, while we assist from the angle of organising the income and expenditure on the sale. The final judgment on the tax amount and the return is made by a tax accountant.

If selling, at what point do you draw the line on rent and the deposit?

In a sale, rent and the deposit are generally drawn at the handover date. When selling a tenanted property (an owner change), based on the handover date, that month's rent is apportioned by the day between seller and buyer, and because the deposit (money held) is succeeded by the buyer together with the position of lessor, it is settled by deducting the deposit amount from the sale price or exchanging it separately. In an inheritance scene, as a premise for selling, inheritance registration is completed first (inheritance registration became mandatory from 1 April 2024), and while in co-ownership, whether to sell by the agreement of all co-owners or to sell a share is decided.

The rent that had already arisen before the division is, as above, acquired by each heir in proportion to their share, so what is drawn at the time of sale is the seller-buyer settlement of "rent and the deposit from the handover date onward," organised as a matter separate from the settlement of pre-division rent among the heirs. At what point and what is drawn, the succession of the lease, and the treatment of the deposit are confirmed in the lease terms and the sale contract.

Settlement item	Point of the line	Who handles it
Rent	Apportioned by the day at the handover date	Sale contract (we organise)
Deposit (money held)	Succeeded by / settled with the buyer at handover	Sale contract (we organise)
Settlement of pre-division rent among heirs	In proportion to share (separate from handover)	Lawyer / administrative scrivener
Inheritance registration	Completed before the sale	Judicial scrivener

Frequently asked questions

Q. One heir is receiving all the rent — can the other heirs get any?
A. Yes. The pre-division rent is said to be acquired definitively by each co-heir as a divided sole claim in proportion to their share (Supreme Court judgment of 8 September 2005), so the heir who received it all should in principle settle with the others in proportion to their shares. Where the allocation or expense-sharing is disputed, a lawyer is involved, and the putting of the agreed content into writing is handled by an administrative scrivener.

Q. If I acquire the rental property in the estate division, does all the pre-division rent become mine too?
A. In principle, no. The Supreme Court holds that the attribution of the pre-division rent claim, which each heir acquired definitively in proportion to their share, is not affected by the later estate division. You can acquire the rental property itself in the division, but the pre-division rent remains fixed as belonging to each heir per their share. There is room for all heirs to agree on a different allocation; consult a lawyer / administrative scrivener on the content.

Q. During the undivided period, who files the tax return on the rent and how?
A. In the National Tax Agency's information, the real-estate income until the estate division is settled is attributed to each heir in proportion to their statutory share and is unaffected by the later estate division. In practice each heir apportions and files by statutory share. For the decedent's death-year portion, the heirs file a quasi-final return. The range and expense allocation vary by case, so confirm with a tax accountant.

Q. When selling a tenanted property, at what point are rent and the deposit drawn?
A. Generally at the handover date. That month's rent is apportioned by the day between seller and buyer, and the deposit, succeeded by the buyer together with the position of lessor, is deducted from the sale price or settled separately. This is the seller-buyer settlement from handover onward, separate from the settlement of pre-division rent among the heirs. As a premise for selling, a judicial scrivener completes inheritance registration (mandatory from April 2024).
