Selling a family home where multiple-stage inheritance (sūji sōzoku) increased the heirs — how to proceed while inheritance registration is still unfinished

In short: Multiple-stage inheritance (sūji sōzoku) is the state where, before inheritance registration was done, another heir also died and the number of heirs involved grew. Selling requires inheritance registration first, but the sale preparation can run in parallel with registration. The keys are confirming all heirs' intentions, how to arrange a mandate to a representative, and the estate division. Registration lies with a judicial scrivener, disputes with a lawyer, and tax with a tax accountant.

This article is for the representative (the eldest son, etc.) who wants to sell a family home that, after a parent's death, had its inheritance registration left undone until another heir also died and the heirs became numerous; it organises the steps to a sale from the Civil Code and the Real Property Registration Act. We handle valuation, the arrangement of the sale and brokerage. The inheritance registration in multiple-stage inheritance lies with a judicial scrivener; estate division in dispute (mediation and adjudication) among heirs with a lawyer; drafting support for the estate-division agreement with an administrative scrivener or the person themselves; and estimates of inheritance tax and capital-gains tax with a tax accountant. 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 mandatory inheritance registration and selling in a single-stage inheritance, see inheritance registration becoming mandatory and selling; for the decision to sell or keep a family home, see should you sell or keep an inherited family home.

What is multiple-stage inheritance, and why do the heirs "increase"?

Multiple-stage inheritance (sūji sōzoku) is the state where, before one person's inheritance process (especially inheritance registration) was finished, one of their heirs died as well and inheritances stacked up. Because the status of the first inheritance's heir is passed to that person's heirs (spouse, children, etc.), the number of people involved grows like a snowball.

An heir succeeds, from the time inheritance begins, to all rights and obligations belonging to the decedent's property (Civil Code Art. 896). Where there are several heirs, the inherited property belongs to them in co-ownership (Art. 898), and each co-heir succeeds to rights and obligations in proportion to their inheritance share (Art. 899). If an heir dies before the estate is divided in the first inheritance, the "estate co-ownership share" that person held passes to the next heirs, stacking into second and third stages. For example, if, after the father's death and before the estate is divided, the mother or siblings die, their spouses and children join as parties too.

State	Who becomes a party
First inheritance (father dies)	The father's heirs, such as the mother and children
Multiple-stage (the mother also dies before division)	The mother's heirs (other children, grandchildren, etc.), who succeeded to the father's heirs' status, also join
Stacking further	Intertwined with representation inheritance, it can spread to spouses, grandchildren, nephews and nieces

Multiple-stage inheritance is a different concept from representation inheritance (where a child who predeceased the decedent is represented by a grandchild). Determining when each inheritance began and who the parties are is a tracing-the-family-register task; the final range of heirs is confirmed by a judicial scrivener or a lawyer.

Is inheritance registration always required before selling? (the order of sale and registration)

As a precondition for the transfer registration on a sale, inheritance registration from the deceased registered holder to the heirs is required. You cannot transfer "under the decedent's name" to the buyer. However, negotiation and preparation of the sale contract can proceed in parallel with inheritance registration.

Inheritance registration became mandatory on 1 April 2024, requiring an application within three years of learning that you acquired the property by inheritance (Real Property Registration Act Art. 76-2). Failure without justifiable grounds is subject to a civil fine of up to ¥100,000 (Art. 164(1)). Even when selling, inheritance registration cannot be avoided. A registration of rights is in principle applied for jointly by the registration holder and the registration obligor (Art. 60). In multiple-stage inheritance, whether the intermediate inheritance was a sole inheritance divides cases into those where the registration can be combined into one and those where it is applied for separately for each inheritance. This judgment and the registration application are the judicial scrivener's area.

Step	Procedure	Who
1	Determine the heirs (collect family registers); divide the estate	Heirs / judicial scrivener / lawyer
2	Inheritance registration from the decedent to the heirs	Judicial scrivener
3	Sale contract and settlement (preparation may run in parallel with 1 and 2)	Us / heirs
4	Transfer of ownership from the heirs to the buyer	Judicial scrivener

How do you obtain all heirs' consent? What if there are distant or overseas heirs?

To sell the inherited property "as a whole," in principle all heirs' agreement (the intention to divide and to sell) is required. If even one objects or does not participate, the sale cannot go ahead. Where there are distant or overseas heirs, exchanging documents and confirming identity take time, so build a contact network early.

Unless prohibited by will, co-heirs may at any time divide all or part of the estate by agreement, and where the agreement is not reached, each co-heir may request division by the family court (Civil Code Art. 907). The effect of estate division is retroactive to the time inheritance began, but it cannot prejudice the rights of third parties (Art. 909). It is usual to put everyone's intention into a document (an estate-division agreement) with registered seals and seal certificates attached. Heirs living overseas obtain, in place of a seal certificate, a signature certificate (shomei証明) and a certificate of residence at the local Japanese embassy or consulate. If the heirs cannot agree and a dispute arises, including mediation and adjudication, that is a lawyer's area. Selling where overseas heirs are involved is also organised in selling Japanese property with heirs living overseas.

Who becomes a party to the sale contract? (mandate to a representative, sale of a share)

In principle, the sellers under the sale contract are all the heirs. In practice, a common form is for everyone to give a power of attorney to a representative (the eldest son, etc.), who acts as the single point of contact for the contract and settlement. Where everyone's steps do not align, there is also the option of selling only your own share, but note that its use is limited and the price tends to fall.

In the state of estate co-ownership, each heir holds a share. To sell the whole, all in principle contract as sellers; when mandating a representative, clarify the scope of the mandate (conclusion of the contract, receipt of the price, handover, etc.) in the power of attorney. Your own share alone can be transferred to a third party without the other heirs' consent, but because you cannot use the whole of the co-owned property, buyers are limited. The final arrangement of who joins the contract as a party, and whether a mandate suffices, is confirmed with a judicial scrivener in relation to registration, and with a lawyer where a dispute is involved.

How to sell	Parties	Points to note
All sell (representative mandated)	All heirs (representative as contact)	Clarify the mandate scope in the power of attorney; all registered seals and seal certificates
Sell only a share	Only the heir holding the share	Buyers are limited and the price tends to fall
Acquire solely by division, then sell	The heir who acquired it	Takes time until the division is agreed

How much do the costs and time come to?

Multiple-stage inheritance tends to swell both costs and time, because the heir investigation and the number of registrations increase. Because amounts and taxes vary greatly by case, here we limit ourselves to organising the cost items and leave the figures to each provider.

The registration licence tax on inheritance registration is calculated by multiplying the fixed-asset-tax valuation by the rate, and the rate for transfer of ownership by inheritance is in principle 4/1,000 (0.4%) (Registration Licence Tax Act; the specific tax base and any reduction are confirmed by a judicial scrivener or tax accountant). In multiple-stage inheritance, if registration is split into several times, the registration licence tax and the judicial scrivener's fee stack up accordingly. Collecting family registers takes time when the registered domiciles are scattered, and with many heirs or overseas residents it can run to months. Capital-gains tax on a sale gain, and the applicability of the acquisition-cost add-on or the vacant-house exemption, are estimated by a tax accountant.

Cost item	Content	Who
Registration licence tax	Inheritance registration is in principle 0.4% of the valuation (plus a separate transfer-registration portion)	Judicial scrivener calculates
Judicial scrivener's fee	Inheritance registration (more items in multiple-stage cases)	Judicial scrivener
Family registers / certificates	Register collection, signature certificates for overseas heirs, etc.	Heirs / judicial scrivener
Brokerage fee	Brokerage commission to the real estate company	Us
Tax	Capital-gains tax; applicability of the acquisition-cost add-on and vacant-house exemption	Tax accountant estimates

We arrange the valuation and sale schedule while watching the heirs' alignment, and handle the sale contract, settlement and brokerage. See inherited-property consultations. For a family home with special rights such as a leasehold, see also explaining leasehold-land property to Chinese-speaking clients. The inheritance registration in multiple-stage inheritance lies with a judicial scrivener, estate-division disputes with a lawyer, and tax with a tax accountant — each an independent entity, engaged separately. We proceed by direct contract, direct invoice and direct payment; no referral or lead-transfer fees are exchanged.

Frequently asked questions

Q. Can I sell the family home without doing inheritance registration?
A. No. As a precondition for the transfer registration to the buyer, inheritance registration from the deceased registered holder to the heirs is required. Inheritance registration became mandatory on 1 April 2024, requiring an application within three years of learning of the acquisition (Real Property Registration Act Art. 76-2). The sale-contract preparation can, however, run in parallel with registration.

Q. What if one heir is overseas and hard to reach?
A. Selling the whole in principle requires everyone's agreement. An overseas heir obtains, in place of a seal certificate, a signature certificate at the local Japanese embassy or consulate. Because the exchange takes time, build a contact network early and clarify the mandate scope in writing. If agreement cannot be reached, it is separated to a lawyer.

Q. Can it not be sold unless all heirs are present? Can I sell only my own share?
A. Selling the whole requires everyone's agreement, but your own share alone can be transferred to a third party without the others' consent. Note, however, that buyers are limited and the price tends to fall because you cannot use the whole co-owned property. We organise which approach is best, and refer to a lawyer where a dispute is involved.

Q. Does multiple-stage inheritance make the registration costs higher?
A. If the intermediate inheritance is not a sole inheritance and registration is split into several times, the registration licence tax (in principle 0.4% of the valuation for inheritance registration) and the judicial scrivener's fee stack up accordingly. Whether it can be combined into one and the calculation are the judicial scrivener's area. Amounts vary by case, so confirm estimates with a judicial scrivener or tax accountant.
