### The Reality: "It Would Have Been Better If I Hadn't Surveyed" - Many Voices Say.
In situations involving the sale or inheritance of real estate, you may be told by real estate agents or judicial scriveners that "a survey is necessary." However, in reality, surveying is not essential in all cases. In the real estate registration system overseen by the Ministry of Justice, situations where a confirmed survey is legally mandated are limited. While surveys are necessary for procedures that change the registered area, such as subdivision or land area correction registration, a survey is not required for inheritance registration itself. Despite this, consultations have been received at real estate-related consultation services from people who were told, "If you inherit, a survey is required as a set," and paid between 300,000 and 800,000 yen (Source: Ministry of Land, Infrastructure, Transport and Tourism "Survey on the Actual State of Land Transactions").
### Mechanism of the Determination Tool
This tool uses AI to determine whether a survey is necessary or not, simply by users inputting their purpose for considering a survey and the current state of the land by answering a few questions.
**Step 1: Select Purpose**
Choose the reason for considering a survey from the following options.
- I want to sell the land
- An inheritance has occurred (or is planned)
- I want to build a new building or renovate/expand an existing one
- I want to confirm the boundary with the adjacent property
- I want to divide the land (subdivision)
- Other
**Step 2: Questions Regarding Land Status**
- Is a cadastral map (area survey map) available at the Legal Affairs Bureau?
- Are boundary markers (stakes, plates) present on the site?
- Are there any discrepancies in the recognition of the boundary with adjacent landowners?
- Are there any significant discrepancies between the official map (kosu) and the current condition?
**Step 3: Output of Determination Result**
Based on the input, the determination result will be displayed in the following three levels:
- "Survey Required": Confirmed survey recommended due to legal requirements or practical necessity.
- "Current Condition Survey May Suffice": Possibility of handling with a less expensive current condition survey instead of a confirmed survey.
- "Survey Not Needed": There is no legal obligation or practical necessity to conduct a survey at this time.
The determination result will include the basis for the judgment, with references to relevant articles and guidelines.
### Many People Do Not Understand the Difference Between Confirmed Surveys and Current Condition Surveys.
Even when speaking of surveys in general, the costs and procedures for "confirmed surveys" and "current condition surveys" differ significantly. A confirmed survey generally requires the participation of all adjacent landowners and the creation of a boundary confirmation document, typically costing 500,000 to 800,000 yen and taking 2 to 4 months. On the other hand, a current condition survey is completed by a land and house surveyor measuring the shape of the land, costing 150,000 to 300,000 yen and taking about 1 to 2 weeks. Even for sales, there are cases where a current condition survey and sale by public record can suffice if the buyer is an individual and the area discrepancy is small. Conversely, if the buyer is a corporation or a government agency, a confirmed survey is almost always required. This tool provides detailed judgments, even going as far as determining "how much of a survey is needed."
### Use Cases
**Case 1: Those inheriting land from deceased parents**
Following the mandatory inheritance registration (enforced April 2024), there is an increasing number of cases where individuals are told "a survey may be necessary" during the inheritance registration process. This tool can prevent situations where people, unaware that a survey is not required for inheritance registration alone, order unnecessary surveys.
**Case 2: Those selling their family land**
Many people are unsure when a real estate agent says, "Please conduct a survey," whether it refers to a confirmed survey or a current condition survey, or if a sale by public record would suffice. By checking with this tool beforehand, you can gain the knowledge necessary for discussions with the real estate agent.
**Case 3: Those with boundary disputes with neighbors**
In cases where fences are misaligned or boundary markers cannot be found, many people are unsure of the first steps to take. This tool can help clarify whether utilizing the boundary demarcation system is appropriate, if a private land and house surveyor should be commissioned, and fundamentally, whether a survey is necessary in the first place.
### Development Roadmap
Survey Cost Navi plans to expand its features in the future, including the ability to request quotes from multiple land and house surveyors simultaneously and to provide content guiding users on the online procedure for obtaining cadastral maps from the Legal Affairs Bureau.
*The determination results of this tool are for reference based on general standards. For individual cases, please consult with experts such as land and house surveyors or judicial scriveners.
