Unjust Possession (Unjust Occupation Damages): Legal Character, Conditions, Scope and Application Problems (in Light of Doctrine and Jurisprudence)

ECRIMISIL (COMPENSATION FOR UNLAWFUL OCCUPATION) – LEGAL NATURE, CONDITIONS, SCOPE, AND PROBLEMS OF APPLICATION (IN LIGHT OF DOCTRINE AND CASE LAW)

1. Introduction

Ecrimisil is one of the most frequently encountered claims in practice, particularly in real property disputes (such as co-ownership, prevention of interference, use following land registry cancellation and registration, inheritance partnership, failure to vacate after lease expiration, boundary encroachment, and occupation of common areas). Although the concept is referred to in everyday language as "occupation compensation" or "unlawful use fee," technically ecrimisil is a special type of compensation aimed at remedying the damage arising from use by a person who holds/uses a real property without the consent of the right holder and without a justified legal reason.

The Court of Cassation's established approach does not view ecrimisil as a debt relationship based on mutual will, such as a lease agreement. On the contrary, it is emphasized that the legal nature of "unlawful occupation" is a tortious act, and that if damage arises from this, it must be remedied. Indeed, in decisions of the Court of Cassation General Assembly and various chambers, it is regularly expressed that ecrimisil corresponds to "at least the equivalent of comparable rental income" and that positive/negative damage elements may fall within its scope.

The purpose of this article is to systematically present the legal nature of ecrimisil (including divergences of opinion in doctrine), its conditions, its method of calculation, problems of litigation and proof, and the divergences between administrative ecrimisil in public real properties and private law ecrimisil.

2. Concept and Legal Nature

2.1. Definition

The prevalent line of definition in doctrine is along the following axis: Ecrimisil is "the compensation that the right holder may claim from the bad faith possessor due to unlawful occupation." Court of Cassation case law also adopts this definition and ties the source of ecrimisil to the fact of unlawful occupation of "bad faith possession."

At this point, two fundamental emphases stand out:

1. Extra-contractual nature: Ecrimisil is not based on a contract that generates "consideration for use" such as a rental debt; a lease relationship established by the convergence of the parties' wills cannot be assumed.
2. Tortious act/special compensation nature: According to the Court of Cassation, unlawful occupation is of tortious nature; ecrimisil is a special compensation that remedies the damage produced by unlawful occupation.

2.2. Principal Approaches in Doctrine (Summary)

In doctrine, several axes are debated in terms of the legal nature of ecrimisil (here, I summarize the dominant orientations by the method of "reference" to doctrine):

• Tort (tortious act) approach: The source of ecrimisil is unlawful interference; within the context of damage-fault causation, the tort provisions of the TCO provide an "explanatory framework." The Court of Cassation's emphasis on "tortious nature" strengthens this approach. However, the fault debate in ecrimisil may not correspond exactly to classical tort doctrine; in particular, the "bad faith" criterion may function differently from fault in the TCO.
• Unjust enrichment approach: The occupant obtains a benefit that falls within the property sphere of the right holder without consideration; the return of this benefit can be explained by the logic of unjust enrichment. However, since the Court of Cassation most frequently characterizes ecrimisil as "special compensation," the unjust enrichment framework is not directly applied to every case; it rather serves as an "alternative/auxiliary explanation."
• Possession provisions approach (connection with TCC Article 995): The liability of the bad faith possessor introduces a special liability regime regarding fruits and damages. The "fruit/income deprivation" dimension of ecrimisil and the "bad faith possessor" condition establish a systematic connection with this provision.

The common ground of these debates is as follows: Ecrimisil is neither a pure rental receivable nor in every case a pure unjust enrichment restitution; practice and case law position it as a special compensation of a sui generis nature arising from unlawful occupation.

3. Conditions of Ecrimisil

3.1. Status of the Right Holder: Being an Owner and/or Right Holder

As a rule, the owner may, pursuant to TCC Article 683, prevent unlawful interference with their real property and assert related compensation claims. However, in Court of Cassation practice, it is accepted that not only the "registered owner" but in some cases also the holder of a personal right may claim ecrimisil. The fundamental issue here is who has the authority to benefit from the real property in the capacity of "right holder."

3.2. Unlawful Occupation / Absence of Justified Reason

For an ecrimisil claim, the use by the possessor must not be based on a justified reason. Justified reason may include grounds such as a lease agreement, a limited real right such as usufruct/residential right, a valid use permit, a partition/inheritance agreement, a court order, or administrative allocation.

An important caveat from the Court of Cassation is: In practice, if a person is using the real property "believing it to be based on a justified reason" or "within the plaintiff's consent," it is possible in each concrete case that the period until the withdrawal of consent may not be characterized as "bad faith and unlawful use." This makes the commencement of ecrimisil debatable, particularly in situations such as intra-family use, cohabitation, and implied permission.

3.3. Bad Faith (The Most Critical Element)

The most determinative condition of ecrimisil is that the user is a bad faith possessor. In Court of Cassation terminology, bad faith is associated with the continuation of possession without the owner's consent and approval, without a justified reason, and with the absence of situations such as the person "not knowing/not being able to know that they have exceeded the boundary" despite exercising the care expected of them.

Bad faith is concretized in many files around the following questions:

• Did the user know (or should they have known) that the real property belonged to someone else?
• Did the owner explicitly object to the use; send a warning notice; file a lawsuit?
• Was there a prior legal relationship between the parties (lease, partnership, intra-family agreement)?
• Was there permission/consent at the outset of the use, and was it subsequently withdrawn?

The determination of bad faith is at the center of practice, as it determines both "whether ecrimisil has arisen" and "from which date it may be claimed."

4. Scope of Ecrimisil: Which Damages Are Included?

Court of Cassation decisions establish a tripartite framework when determining the scope of ecrimisil:

1. Positive damages such as deterioration from normal use (such as wear and tear of the real property)
2. Positive damages arising from use (such as disruption of the business order)
3. Lost benefit (negative damage): Most typically, "deprivation of comparable rental income"

In most files in practice, ecrimisil is predominantly determined based on the comparable rental value. While the Court of Cassation states that ecrimisil corresponds to "at a minimum the equivalent of rental income," there exists a framework where in some decisions the emphasis of "at a maximum full income deprivation" can also be seen. This may open the door to broader income loss debates beyond mere rental comparables, especially in commercial enterprises/income-generating places; however, the burden of proof and expert examination for this is heavier.

5. Calculation of Ecrimisil and Proof

5.1. Comparable Rental Research and Expert Examination

In private law ecrimisil cases, courts generally have the ecrimisil calculated on a "periodic" basis through an expert, based on data such as:

• Nature of the real property (residential, workplace, land),
• Location, frontage, access, utility,
• Market conditions by period,
• Comparable rental agreements/listings,
• Duration of occupation and intensity of use.

The critical sources of error here are:

• Failure to select comparables from the same locality/of similar nature,
• Calculating all years with a single figure without periodization,
• Disregarding the actual intensity of use (partial use),
• Failure to correctly determine the commencement and termination of the justified reason/consent period.

5.2. Commencement Date

The commencement date is connected to the moment when bad faith began. For example:

• If the owner sent a warning notice and requested the termination of the use, the period following the notice is most often more readily accepted as "bad faith use."
• If the lease agreement has ended and the real property has not been vacated, ecrimisil debates regarding the post-agreement period are separately regulated in Article 75 of Law No. 2886 for public real properties; in private law, an "unlawful occupation" assessment is made for the contractless period.

5.3. Issue of Statute of Limitations / Period Limitation

Article 75 of Law No. 2886 for public real properties explicitly states that ecrimisil may be determined "not exceeding five years retroactively from the date of determination." In private law ecrimisil, the period/statute of limitations issue is more technical, and debates on tort/personal claim statute of limitations may be conducted depending on the nature of the event. (This article, limited to the given source set, records the 5-year retroactive determination limit for public real properties as a clear basis.)

6. Difference Between Ecrimisil and Rental Receivable

When ecrimisil and rental receivable are confused, both jurisdiction/venue debates and proof-calculation errors arise. The fundamental differences:

• Rental: Based on a contract; there is a debt relationship; the parties' wills have converged.
• Ecrimisil: There is no contract; there is unlawful occupation; the compensation character is dominant; bad faith is determinative.

The Court of Cassation's emphasis that it "cannot be equated with lease" sharpens this distinction. The use of the comparable rental value as a "calculation criterion" does not transform ecrimisil into a rental receivable.

7. Consent-Based Use, Subsequent Withdrawal of Consent, and Ecrimisil

This is one of the areas that most frequently generates disputes in practice. For example:

• If the owner gave permission for "temporary residence" to a relative,
• If a de facto partition or an implied use arrangement has formed among co-owners,
• If the real property was left for "free use" for a period,

the question of whether ecrimisil arises during these periods, and if it does, from which date, is debated. The Court of Cassation states that consent-based use may in some cases not be considered "unlawful and bad faith," and that the assessment may change with the withdrawal of consent. For this reason, warning/caution correspondence, messages, witness testimony, and the form of actual use are determinative evidence in ecrimisil cases.

8. Administrative Ecrimisil Regime in Public Real Properties (Law No. 2886 Article 75)

In public real properties, ecrimisil is most often established as an administrative act and differs from private law ecrimisil in the following respects:

• "The administration need not suffer damage; fault of the unlawful occupant is not required" (Article 75).
• Retroactive determination is limited to "five years."
• Collection and eviction mechanisms (enforcement pursuant to Law No. 6183, eviction through the provincial governor, etc.) are tied to special regulations.

In this regime, ecrimisil approaches the character of "public receivable/monetization of occupation" rather than the private law compensation logic. For this reason, the competent judicial path, objection, and litigation strategy also most often shift to the administrative court axis.

9. Systematics of Court of Cassation Case Law (Selected Principles)

The main principles that recur in Court of Cassation decisions can be summarized as follows:

• Ecrimisil is a compensation that the right holder may claim from the bad faith possessor (General Assembly line).
• Unlawful occupation cannot be equated with a lease agreement; it is of tortious nature.
• Ecrimisil is "a special form of damage remedy" and corresponds to at least the equivalent of comparable rental income.
• The scope may include both positive damages (wear and tear, etc.) and negative damage (lost benefit).
• Determination of bad faith and whether the use is based on a justified reason are at the center of the dispute.

These principles are the "backbone" that determines the structure of the petition and the objection strategy against expert reports in ecrimisil cases.

10. Evaluation in Lieu of Conclusion

The institution of ecrimisil is an indispensable tool in practice for effective protection of the right to property (TCC Article 683). However, the institution "appearing like lease" (being calculated by comparable rental) creates conceptual confusion in most files. For the correct result, in each case the following must be clarified:

1. Whether the use is based on a justified reason,
2. Whether the user is to be considered bad faith,
3. Which damage items ecrimisil will cover,
4. According to which comparables and which periods the calculation will be made.

For public real properties, the special regime of Article 75 of Law No. 2886 must additionally be taken into account; elements such as the non-requirement of fault/damage, administrative determination, and the 5-year retroactive limit must be evaluated separately.
