Can inherited land be sold while the boundary is unfixed? When a confirmed survey is needed

In short: inherited land can be sold even while the boundary is unfixed. But buyers and financial institutions often ask for a "confirmed survey plan," and without one the price may fall or handover may be delayed. If the boundary becomes a dispute, you move to the boundary-determination system (Real Property Registration Act Art. 123 onward; in force from 2006) or to subdivision registration — both the work of a land and house surveyor. Ordering the inheritance registration (judicial scrivener) and the capital-gains tax (tax accountant) alongside the survey reduces backtracking. The way of selling and brokerage are handled by our company (Yotsuba Real Estate Co., Ltd.) as information; the survey and boundary determination are handled by qualified professionals.

Many heirs realise, on trying to sell inherited land or a family home, that "there is no boundary marker with the neighbour" or "only an old survey plan exists." Can it be sold with the boundary unfixed? When, and to whom, do you order a confirmed survey? This article is for heirs considering selling inherited land: what to confirm first and who to consult, set out from the Real Property Registration Act, the Civil Code and the Land and House Surveyor Act. The way of selling, valuation and brokerage are handled by our company (Yotsuba Real Estate Co., Ltd.) as information; the survey and boundary determination by a land and house surveyor, and legal judgment by qualified professionals.

Can inherited land be sold while the boundary is unfixed?

Selling itself is possible. A fixed boundary is not an absolute condition of a sale contract; if the parties agree, a sale "as-is (current condition)" is possible. In practice, though, a confirmed survey plan is often demanded for the following reasons, and its absence tends to be a disadvantage.

Who	Why they want a confirmed survey plan
Buyer	To avoid a boundary/area dispute with the neighbour after buying. To fix walls and any encroachment
Financial institution	To fix the area and extent for the collateral valuation of the buyer's mortgage
Seller (you)	If the registered area differs from the actual measurement, it affects price and handover

"Can be sold" and "can be sold favourably" differ. It can be sold with the boundary unfixed, but buyers become harder to find, or price and handover timing may shift on a confirmed-survey condition. Inherited-property selling in general is at inheritance and real estate; whether consent is needed to sell co-owned land is at selling inherited co-owned real estate.

What is the difference between a confirmed survey plan, a current-condition survey plan and a land-area survey plan?

"Survey plan" comes in kinds, and they differ in how much they bite on a sale. Confusing them leads to "I thought there was a survey plan" but it turns out unusable.

Kind	What plan it is	Neighbour attendance / consent	Position in a sale
Confirmed survey plan (boundary-determination plan)	A plan fixing every boundary through attendance and confirmation by owners of adjoining land, roads, etc.	Yes (private and public land)	Most trusted in transactions; the basis for "survey confirmed"
Current-condition survey plan	A plan merely measuring the current state — block walls, existing stakes	No	Only a guide; no power to fix the boundary
Land-area survey plan	A plan showing a parcel's area, shape and calculation method, kept at the Legal Affairs Bureau (Real Property Registration Regulations Art. 77)	Depends on when made (old ones may be boundary-unfixed)	Made at subdivision / area-correction registration; accuracy varies greatly by era

Thinking "there's a survey plan" when only a current-condition survey plan exists is risky. A current-condition survey plan merely measures walls and existing stakes and, lacking confirmation by adjoining owners, has no power to fix the boundary. An old land-area survey plan from the Showa era may lack boundary markers or coordinates and be less accurate than a modern confirmed survey plan. What lets you say "confirmed survey plan available" in a sale is a confirmed survey plan reached through attendance and confirmation by all owners of adjoining land and roads.

Whom do you order a confirmed survey from, and how much do cost and time run?

A confirmed survey (a survey accompanied by boundary determination) and the subsequent subdivision / area-correction registration are the work of a land and house surveyor (Land and House Surveyor Act Art. 3 — agency for registration of real property description and for boundary-determination procedure, etc.). As a licensed real estate agent, our company cannot perform surveys or registration, so where a confirmed survey is needed we connect you to a land and house surveyor.

Item	Guide (general tendency)
Who to ask	Land and house surveyor
Time	Often several months, depending on the schedule of attendance by neighbours and road managers
Cost	Varies by land size, number of neighbours, and whether a public-private boundary (road etc.) is involved
Public-private boundary	If it abuts public land such as a road or ditch, a public-private boundary confirmation with the municipal road manager is added, tending to extend the period

Cost and time vary more by "how many neighbours and road managers there are" than by land size. In inheritance cases, the neighbour's owner may also have died with heirs split among many, so attendance can take time. Before fixing the sale schedule, confirm with the land and house surveyor whether a confirmed survey plan exists and, if not, the estimated time the confirmed survey will take — this keeps the plan from collapsing. As for costs, the Civil Code's principle is that the cost of setting boundary markers is borne equally by the neighbours, and survey costs in proportion to the size of the land (Civil Code Arts. 223 and 224).

What do you do when you cannot agree with the neighbour on the boundary (boundary determination, subdivision)?

When you and the neighbour disagree on the boundary, rather than going straight to litigation, there is the route of using the boundary-determination system first. Boundary determination is a system where, on the application of the land's registered owner, etc., the boundary-determination registrar, following the opinion of boundary investigation committee members (external specialists), specifies the on-site position of the boundary (the points and lines that formed the border of a parcel when it was registered) (Real Property Registration Act Art. 123 onward — Chapter 6; in force 20 January 2006).

Stage	Content	Who
Attendance / confirmation	Confirm the boundary with attendance by neighbours and road managers	Land and house surveyor
Cannot agree	Application for boundary determination (registrar specifies the boundary position)	Land and house surveyor (procedure agency)
Subdivision / area correction	After determination, subdivision / area-correction registration as needed	Land and house surveyor
Dispute reaches ownership	Dispute over the extent of ownership (boundary-confirmation lawsuit, etc.)	Lawyer

Boundary determination is an administrative procedure that specifies the position of the "boundary (the public-law border)"; it does not decide the attribution of ownership itself. If the trouble with the neighbour develops into a dispute over the extent of ownership, it is the lawyer's territory. Our company assists with the brokerage / sale of land once the boundary is fixed and it is sellable. For selling land short on frontage, inherited non-rebuildable property is also helpful.

How do you order the inheritance registration, tax and the survey?

Selling inherited land involves several processes: transferring the registered name to the heirs (inheritance registration), fixing the boundary (confirmed survey), and selling and settling the capital-gains tax. Dividing the roles:

What to do	Who
Way of selling, valuation, finding a buyer, brokerage, sale contract	Licensed real estate agent (Yotsuba Real Estate Co., Ltd.)
Confirmed survey, boundary determination, subdivision / area-correction registration	Land and house surveyor
Inheritance registration (deceased → heirs), ownership-transfer registration	Judicial scrivener
Preparation of the estate-division agreement	Administrative scrivener (Yotsuba Administrative Scrivener Office)
Capital-gains tax, acquisition-cost add-on	Tax accountant
Dispute over rights with the neighbour	Lawyer

Inheritance registration must be applied for within three years of learning of the acquisition (Real Property Registration Act Art. 76-2; effective 1 April 2024). It cannot be skipped even to sell. For the capital gain on selling inherited land, there is a special measure adding part of the inheritance tax to the acquisition cost if sold within a set period (Act on Special Measures Concerning Taxation Art. 39 — acquisition-cost add-on for inherited property; sales up to the day three years after the day following the inheritance-tax filing deadline qualify); the specific calculation and filing are handled by a tax accountant. The key to the order is "start the inheritance registration and confirmed survey early, in line with the sale schedule." A confirmed survey can take several months, and a late start pushes handover back.

Frequently asked questions

Q. There isn't a single boundary marker. Can it still be sold?
A. Selling itself is possible, but buyers and banks often want a confirmed survey plan, and without one price and handover timing tend to be affected. A confirmed survey fixes every boundary through attendance by neighbours and road managers, and is the work of a land and house surveyor. Before fixing the sale schedule, confirm the estimated time the confirmed survey will take so the plan does not collapse.

Q. A "land-area survey plan" is at the Legal Affairs Bureau. Can I call it survey-confirmed?
A. Not necessarily. A land-area survey plan shows a parcel's area and shape and is kept at the Legal Affairs Bureau (Real Property Registration Regulations Art. 77), but an old one may lack boundary markers or coordinates and not have gone through neighbour confirmation. What lets you say "confirmed survey plan available" in a sale is one reached through attendance and confirmation by all owners of adjoining land and roads. Confirm the era of creation and content with a land and house surveyor.

Q. The neighbour won't attend the boundary confirmation. What do I do?
A. When you cannot agree at the attendance, or the neighbour won't attend, there is the route of the boundary-determination system (Real Property Registration Act Art. 123 onward). It is an administrative procedure where the boundary-determination registrar specifies the boundary position following the opinion of boundary investigation committee members; the procedure agency is a land and house surveyor. If it develops into a dispute over the extent of ownership itself, it is the lawyer's territory.

Q. Which do you do first, the inheritance registration or the confirmed survey?
A. The inheritance registration (judicial scrivener) is done first to fix the name for the sale (application within three years of learning of the acquisition — Real Property Registration Act Art. 76-2). Because a confirmed survey (land and house surveyor) can take several months, it is safer to run it in parallel early once the sale schedule is in view. We organise the whole picture and the order at the valuation stage.
