Real Estate Disputes in Japan: Valuing Claims for Ownership Confirmation and Property Surrender

Real estate often represents a significant asset for businesses and individuals alike. Consequently, disputes concerning property rights – from establishing clear ownership to recovering possession – are a common feature in legal systems worldwide. In Japan, when such disputes escalate to litigation, a crucial initial step is the determination of the "Sogaku" (訴額), or the value of the subject matter of the action. This valuation is pivotal, as it directly influences which court will hear the case and, importantly, forms the basis for calculating the mandatory court filing fees. This article will explore how "Sogaku" is assessed for two fundamental types of real estate claims in Japanese civil litigation: actions for the confirmation of ownership and actions for the surrender (or delivery) of property.

The Foundational Element: Determining the "Value of the Property" (Mokuteki Butsu no Kagaku)

For most legal claims involving real estate in Japan, the "Sogaku" is directly derived from the economic value of the property itself. The methods for ascertaining this value are well-established, aiming for objectivity and predictability.

1. Primary Basis: Fixed Asset Assessment Value (固定資産評価額 - Kotei Shisan Hyōkagaku)

The standard starting point for valuing real property for "Sogaku" purposes is its Fixed Asset Assessment Value. This is the value assigned to land and buildings by municipal authorities for the purpose of levying fixed asset tax (property tax). This principle is outlined in Guideline 1 of the highly influential "Sogaku Notification" (訴額通知 - Sogaku Tsūchi), an administrative directive from the Supreme Court's General Secretariat that guides claim valuation.

To substantiate this value, parties initiating a lawsuit typically submit an official Certificate of Fixed Asset Valuation (固定資産評価証明書 - Kotei Shisan Hyōka Shōmeisho) obtained from the relevant city, ward, town, or village office where the property is located.

It's worth noting that historically, there have been periods where general adjustments were applied. For instance, for a period commencing April 1, 1994, the "Sogaku" for land was, "for the time being," calculated as one-half of its Fixed Asset Assessment Value. While such specific temporary adjustments might change over time, the general reliance on the official Fixed Asset Assessment Value as the baseline remains a core principle. Therefore, it is always essential to verify the current specific rules and any applicable adjustments when undertaking a "Sogaku" calculation for present-day litigation.

2. Alternative Basis: Transaction Price or Market Value (取引価格 - Torihiki Kakaku)

In situations where a Fixed Asset Assessment Value is unavailable (e.g., for certain types of unregistered structures, or unique land parcels not yet formally assessed for tax purposes) or where it is demonstrably inappropriate for the specific circumstances, the actual transaction price (if the dispute arises from a recent sale) or the fair market value of the property may be used as the basis for "Sogaku". Evidence for this could include sales contracts, independent appraisals, or other market data.

3. Specific Valuation Scenarios for Real Property Components:

Japanese practice also provides guidance for more specific situations:

• Unvalued Buildings: For newly constructed buildings or other structures not yet reflected in the Fixed Asset Assessment system, their value might be estimated based on standardized construction cost tables maintained by the Legal Affairs Bureaus (法務局 - Hōmukyoku). These often include a "New Building Price Certification Standard Table" (新築建物価格認定基準表 - Shinchiku Tatemono Kakaku Nintei Kijunhyō) and a "Depreciation Limit Table" (減額限度表 - Gengaku Gendohyō) to account for age and condition.
• Unvalued Land Types: For certain types of land that may not have a standard assessment comparable to residential or commercial plots (e.g., public roads, waterways, cemetery plots owned privately), their valuation might be pragmatically based on a percentage (for instance, one-half) of the Fixed Asset Assessment Value of nearby standard land categories like residential land. This acknowledges their potentially limited marketability or restricted use.
• Standing Trees (with Ritsumoku Registration): For disputes involving standing trees that are registered as independent real property under the Act on Standing Trees (立木に関する法律 - Ritsumoku ni Kansuru Hōritsu), their value for "Sogaku" purposes would typically be determined by an appraisal from a relevant body, such as a forestry association or a qualified expert.

"Sogaku" for Actions for Confirmation of Ownership (所有権確認の訴え - Shoyūken Kakunin no Uttae)

When a plaintiff seeks a judicial declaration to confirm their ownership of a piece of real estate, the "Sogaku" of the claim is, as a general rule, the full assessed value of that real property. This is based on Guideline 1 of the "Sogaku Notification."

• Rationale: The plaintiff is asserting their entire, unencumbered ownership interest. The economic value of successfully establishing this full title is considered equivalent to the property's total objective value.
• No Reduction for Encumbrances (Generally): When an owner files an action to confirm their own title, the "Sogaku" is based on the property's full value, even if the property is subject to lesser third-party rights such as leases, superficies, or security interests (e.g., mortgages). These encumbrances do not diminish the value of the underlying ownership right being asserted by the plaintiff owner for the purpose of this specific "Sogaku" calculation. The core issue is the confirmation of the plaintiff's ultimate title.
• Confirmation of a Co-ownership Share: If a plaintiff is seeking to confirm their fractional share in a property co-owned with others (共有 - kyōyū), the "Sogaku" is calculated as the full value of the property multiplied by the plaintiff's asserted fractional co-ownership interest. For example, if a property is valued at 60,000,000 yen and the plaintiff claims a one-third co-ownership share, the "Sogaku" for their confirmation claim would be 20,000,000 yen.

"Sogaku" for Actions for Surrender/Delivery of Real Estate (不動産の引渡し(明渡し)請求 - Fudōsan no Hikiwatashi (Ake Watashi) Seikyū)

Unlike actions purely for the confirmation of ownership title, claims that primarily seek the possession or surrender of real property often have a "Sogaku" that is calculated as a fraction of the property's full value. This reflects that the immediate legal battle is over the right to possess and use the property, which, while a significant component of ownership, is procedurally valued differently from a claim to establish the entirety of the title itself. The specific fraction depends on the legal basis of the claim for surrender.

A. Claim for Surrender Based on Ownership (Shoyūken ni Motozuku Baai)

• Rule: When the undisputed owner of a property (or one whose ownership is not the primary point of contention in this specific claim for possession) sues for the surrender of that property from a party who is allegedly occupying it without legal right, the "Sogaku" is one-half (1/2) of the property's full assessed value. This is stipulated by Guideline 7(1) of the "Sogaku Notification."
• Rationale: The underlying ownership is presumed or established; the action focuses on vindicating the possessory aspect of that ownership. The legal system assigns a value to recovering possession that is distinct from establishing title ab initio. It's considered that the owner already holds the "exchange value" or bare title, and the suit is to recover the use and enjoyment.
• Example: A property is valued at 80,000,000 yen. The owner sues an unlawful occupant for surrender. The "Sogaku" for this action would be 40,000,000 yen.
• Seeking Removal of Structures and Surrender of Land: If an owner sues to have unauthorized structures built by another party removed from their land and for the surrender of the land itself, the claim is primarily viewed as one for the surrender of the land based on ownership. The removal of the structures is a necessary step to achieve the land's full surrender. The "Sogaku" is generally based on the value of the land (i.e., one-half of the land's assessed value).

B. Claim for Delivery Based on Possessory Right (Sen'yūken ni Motozuku Baai)

• Rule: If a claim for the delivery or recovery of property is based purely on a prior possessory right (sen'yūken), such as in an action for recovery of possession (占有回収の訴え - sen'yū kaishū no uttae), the "Sogaku" is one-third (1/3) of the property's full assessed value. This is outlined in Guideline 7(2) of the "Sogaku Notification." The same fraction (1/3) also applies if the action is for the confirmation of a possessory right.
• Rationale: A purely possessory right, while legally protected, is considered a less extensive interest than full ownership or qualified rights of use like leaseholds. Therefore, the economic value attributed to its recovery or confirmation is correspondingly lower.

C. Claim for Delivery Based on Superficies, Emphyteusis, or Leasehold Rights, etc. (Chijōken, Eikosakuken, Chinshakuken-tō ni Motozuku Baai)

• Rule: When a party holding a recognized right of use over real property—such as a right of superficies (地上権 - chijōken, a right to use another's land for owning structures), emphyteusis (永小作権 - eikosakuken, a long-term agricultural tenancy right), or a leasehold right (賃借権 - chinshakuken)—sues for delivery or possession of the property based on that specific right, the "Sogaku" is one-half (1/2) of the property's full assessed value. This is per Guideline 7(3) of the "Sogaku Notification." This fraction also applies to actions seeking the confirmation of these types of rights.
• Rationale: These rights grant substantial and often long-term rights of use and enjoyment, which are economically significant and valued similarly to ownership-based possessory claims for "Sogaku" purposes.

D. Claim for Surrender Based on a Contractual Relationship (e.g., Termination of Lease) (Keiyaku Kankei ni Motozuku Baai)

• Rule: If a landlord or property owner sues for the surrender of real property due to the termination (e.g., for breach of contract) or expiration of a lease agreement or other contractual right of occupation, the "Sogaku" is one-half (1/2) of the property's full assessed value (Sogaku Notification, Guideline 7(4)).
• Rationale: This situation is procedurally analogous to an ownership-based surrender claim. The plaintiff is seeking to recover full possession and use based on the cessation of the defendant's contractual right to occupy the premises.

The Interplay: Joining Claims for Ownership Confirmation and Property Surrender

It is a common litigation strategy for a plaintiff to simultaneously seek both a judicial confirmation of their ownership of a property and an order for the defendant to surrender that same property. In such instances of joined claims:

• Common Economic Interest: These two claims, though legally distinct, are generally considered to be aimed at achieving a common economic interest for the plaintiff: the full and undisputed enjoyment of their ownership rights, including possession.
• Application of the Absorption Rule: Therefore, the "Sogaku" for the combined action is not calculated by simply adding the "Sogaku" for ownership confirmation (full property value) to the "Sogaku" for surrender (half property value). Instead, under the "absorption rule" (Article 9, Paragraph 1, proviso of the Code of Civil Procedure), the "Sogaku" is determined by the higher of the individual values of the claims sharing that common interest.
• Resulting "Sogaku": Since the "Sogaku" for ownership confirmation (full property value) is typically higher than that for a surrender claim based on ownership (half property value), if both claims are properly joined concerning the same property between the same parties, the effective "Sogaku" for the entire action will usually be the full value of the property.

Practical Steps and Evidentiary Requirements in Real Estate "Sogaku"

For litigants involved in real estate disputes in Japan, certain practical steps related to "Sogaku" are important:

• Obtain Official Valuation: The primary document is usually the Certificate of Fixed Asset Valuation. This should be obtained promptly from the relevant municipal office.
• Address Valuation Gaps: If the official certificate is unavailable (e.g., for a newly built unassessed property) or does not cover all aspects of the disputed property (e.g., specific unregistered structures or unique land features), supplementary valuation evidence may be needed. This could involve relying on standardized construction cost tables from Legal Affairs Bureaus, obtaining appraisals for specific components like standing trees, or using comparative market data for unusual land types.
• Plaintiff's Declarations: In some limited situations where objective valuation is initially difficult, a reasoned declaration (jōshinsho) from the plaintiff regarding the property's value, along with any supporting informal evidence, might be provisionally considered by the court at the filing stage, subject to later scrutiny.

Conclusion: A Structured Approach to Valuing Real Property Claims

The Japanese legal system employs a structured and detailed approach to determining the "Sogaku" for real estate disputes. Claims for the confirmation of ownership are generally valued at the full assessed value of the property, reflecting the comprehensive nature of the right being asserted. In contrast, claims primarily seeking the surrender or delivery of property are typically valued at a fraction (commonly one-half or one-third) of the property's full value, with the specific fraction depending on the legal basis of the claim (ownership, possessory right, leasehold, etc.). The Fixed Asset Assessment Value serves as the cornerstone for property valuation in these calculations.

An accurate "Sogaku" determination is not just a procedural formality; it is a critical factor that directly impacts court filing fees, which can be substantial in high-value real estate litigation, and also determines the competent court. Given the significant financial implications and the nuances of applying these valuation rules to specific factual scenarios (such as co-ownership, joined claims, or properties with unusual characteristics), businesses and individuals involved in real estate disputes in Japan are strongly advised to seek guidance from experienced Japanese legal counsel. Such expertise is invaluable for ensuring proper claim valuation, managing litigation costs effectively, and strategically navigating the Japanese judicial process.
