PROTECTION OF OWNERSHIP IN PROPERTY LAW AND THE ORIGIN OF THE CONCEPT OF COMPENSATION FOR UNLAWFUL USE OF PROPERTY

Property law is the body of rules that regulates individuals' absolute control over their property, defines the limits of this control, and determines the legal remedies to be pursued in case of its violation. One of the fundamental principles of the Turkish Civil Code (TMK) is that the owner has the right to dispose of, use, and benefit from their property as they wish. However, in social life and property relations, situations where these legal rights are violated, and movable or immovable property is occupied by others without the owner's consent, are frequently encountered.

Regarding the concept of compensation for unlawful occupation (ecrimisil), the legal system has developed various compensation mechanisms to eliminate the economic loss caused by the owner's deprivation of their property and the unjust benefit obtained by the wrongful possessor. One of the most important of these mechanisms, and one that causes the most hesitation in practice, is ecrimisil, or compensation for unlawful occupation. Discussed in depth in legal doctrine and judicial decisions, ecrimisil is neither purely tort compensation nor a typical contractual claim; with its unique characteristics, it constitutes a financial protective shield for the right to property. In this study, the institution of ecrimisil will be comprehensively examined in terms of its legal nature, conditions, claim requirements, calculation methods, statute of limitations rules, and its relationship with other legal institutions, with academic depth but in a simplicity that is understandable to everyone, without the use of any tables.

1. LEGAL NATURE AND DEFINITION OF COMPENSATION FOR UNLAWFUL OCCUPATION OF PROPERTY

Ecrimisil, a legal term of Latin origin, literally means "compensation for use" or "rent-like payment." In Turkish legal doctrine and Supreme Court jurisprudence, ecrimisil is defined as the compensation that a person who unjustly possesses, uses, or disposes of another's property without a legitimate gift, lease, or other legal basis, is obligated to pay to the owner.

When the legal nature of compensation for unlawful use of property is examined, it is seen that this institution has a dual character:

• Being a Result of Unlawful Occupation: Similar to tort compensation, as it arises from an unlawful act (unlawful possession). Taking possession of property against the owner's will constitutes an unlawful act.

• Compensation for Use (Similar to Rent): The unlawful possessor has unjustly appropriated the benefit (income) that the owner would have obtained by using the property. Therefore, compensation for unlawful use is calculated based on the probable income (market rental price) that the owner would have obtained if they had rented out the property.

As accepted in the decisions of the Supreme Court's Jurisprudence Unification Board, compensation for unlawful occupation is a type of compensation for wrongful occupation and is a deterrent and compensatory mechanism intended against those who unjustly restrict the rights of the owner stemming from their property rights.

2. CONDITIONS NECESSARY FOR THE ARISING OF A CLAIM FOR COMPENSATION FOR UNLAWFUL USE OF PROPERTY

Not every instance of unlawful seizure or possession automatically necessitates the payment of compensation for unlawful use of property. For a claim for compensation for unlawful use of property to be accepted by the court, certain legal and factual conditions must be met simultaneously.

A. Unlawful Possession and Lack of Legal Basis

The person using or possessing the property must not have a valid legal reason justifying their use. For example, if there is a valid lease agreement, usufruct right, surface right, consent, or legal authorization (such as authorization under guardianship or custody), that use is lawful and no compensation for unlawful use can be claimed. However, if the person does not vacate the property even after the contract has expired, been terminated, or has lost its legal validity, their possession becomes unlawful.

B. The Principle of Good Faith and the Condition of Prohibition (Warning) of Intifada

In the field of compensation for unlawful use of property, the most critical issue, and the one most frequently confused in practice, is whether the occupier acted in "good faith." The situation becomes even more specific when co-ownership (joint ownership) or joint ownership (ownership in partnership) is involved.

• Condition for Prevention of Use in Joint Ownership: If one of the co-owners is using a jointly owned property (such as a house or field) alone and preventing the other co-owners from using it, the other co-owners can only claim compensation for unauthorized use if they have notice of prevention of use . In other words, unless the other co-owners have explicitly stated their intention to use the property, such as "I also want to use this property; give me my share or pay me the usage fee," they cannot claim compensation for past unauthorized use.

• Exceptions to the Condition of Prohibition of Use: There are exceptions where a warning of prohibition of use is not required in every case. If the jointly owned property is a joint business, factory, or commercial facility; and one of the owners has explicitly seized the other's share, denied the title deed, or leased the property entirely to third parties and collected the rental income alone, then compensation for unauthorized use can be demanded directly without the need for a separate warning of prohibition of use.

C. Damage and Causal Link

The owner must be unable to use their property and therefore suffer economic deprivation. However, according to Supreme Court precedents, in calculating compensation for unlawful occupation, it is not a requirement that the owner has actually suffered damage or intended to rent out the property; the unlawful occupation of the property and the deprivation of the rental income it would normally generate for compensation to arise.

3. STATUTE OF LIMITATIONS IN UNLAWFUL USE OF PROPERTY CASES

The question of which statute of limitations applies to claims for compensation for unlawful use of property has been debated for a long time in legal doctrine, but this matter has been definitively settled by the decisions of the Supreme Court's General Assembly of Civil Law.

• Five-Year Statute of Limitations: Although compensation for unlawful use of property is not, by its nature, the product of a tort, to a five-year statute of limitations Appeals. This period is parallel to the statute of limitations periods for rent receivables and similar periodic obligations in the Turkish Code of Obligations.

• Retroactive Calculation Limit: The plaintiff property owner can claim compensation for unlawful occupation for a maximum period of five years prior to the date of filing the lawsuit . Compensation for unlawful occupation for periods older than five years will be forfeited if the defendant raises the statute of limitations defense. This is a crucial procedural rule demonstrating that rights holders should not delay in seeking their rights.

• Commencement of Statute of Limitations: The statute of limitations begins to run from the date on which the compensation claim for each period (month or year) becomes due (payment time arrives). Therefore, a separate statute of limitations calculation may be applicable for each month.

4. METHODS AND CRITERIA FOR CALCULATING UNLAWFUL USE OF PROPERTY FEE

Although the amount of compensation for unlawful use of property is determined at the discretion of the judge, this discretion cannot be arbitrary and must be calculated based on scientific data through expert appraisers. Courts meticulously examine the following criteria when determining the amount of compensation for unlawful use of property:

• Comparative Rental Agreements: The current rental prices of similar properties (apartments, plots of land, fields, commercial properties of the same type) in the area where the property is located, for the period in question, are taken as comparable prices.

• Physical and Locational Characteristics of the Property: The property's surface area, location, transportation links, infrastructure, depreciation, frontage, building quality, and intended use (residential, commercial, agricultural, etc.) directly affect the calculation.

• Income Generating Potential: If the property is a field, the type of crop grown on that field, its yield, and the average agricultural income in the region (net income method) are considered. If it is a plot of land, the rental income it could generate as vacant land or the economic value provided by any structures on it are taken into account.

• Investments Made by the Occupier: If the unlawful possessor (occupier) has constructed a facility on the property that increases its value through their own efforts and expenses, these additional incomes generated by their own investments are not included in the calculation of compensation for unlawful use; in other words, compensation cannot be imposed on the owner based on the value created by the occupier's own labor, only the market value that the property would naturally obtain is taken as the basis.

5. COMPARISON OF COMPENSATION FOR UNLAWFUL USE OF PROPERTY WITH OTHER LEGAL INSTITUTIONS

To clearly define the boundaries of the institution of compensation for unlawful use of property, it is necessary to understand its differences from other institutions in property law and contract law.

A. Lawsuit for Prevention of Interference (Prevention of Seizure) and Compensation for Unlawful Use of Property

• The lawsuit to prevent interference is prospective and aims to stop the ongoing wrongful seizure.

• Ecrimisil, on the other hand, is retroactive; it is the compensation demanded for the period in question when the wrongful occupation occurred, not exceeding a limit of five years prior to that time.

• In practice, these two lawsuits are usually filed together (alternatively or simultaneously) with the same petition. However, it is also possible to file a separate lawsuit for compensation for unlawful use of property without first requesting the prevention of interference.

B. Lawsuit for Compensation for Unlawful Use of Property (Material Damage)

• Ecrimisil compensates for the loss of income, similar to rent, resulting from the non-use of the property.

• A claim for pecuniary damages is filed to compensate for damages caused by an unlawful occupant to the property itself (physical structure) (e.g., demolishing a wall, removing plumbing, cutting down trees). Compensation for unlawful occupation and pecuniary damages are two completely different types of claims and can be demanded together.

C. Differences Between Compensation for Unlawful Use of Property and Rent

• The rental fee is based on a valid lease agreement concluded between the parties, and the amount is determined by the parties within the framework of freedom of contract.

• Compensation for unlawful occupation, on the other hand, does not arise from a contractual relationship but from an unlawful occupation; its amount is determined not by the will of the parties, but by the court according to market rates based on expert reports.

6. CASE STUDIES AND SOLUTIONS ENCOUNTERED IN PRACTICE

Examining how theoretical knowledge translates into real-life applications is crucial for understanding the functioning of the ecrimisil institution.

• Case Study 1 (Occupation Among Heirs): Ahmet, one of the heirs, has been operating a jointly owned shop inherited from their father as a hardware store for many years without the consent of his siblings. If the other siblings wish to file a claim for compensation for unlawful occupation against Ahmet, they must first a notice to Ahmet prohibiting him from using the property. Compensation can be claimed for the period of unlawful occupation after the notice is served; however, for the period before the notice, the claim will be rejected as the condition of prohibiting unlawful occupation has not been met.

• Case Study 2 (Tenant Whose Contract Has Expired): 's lease agreement expired one year ago. Despite a written agreement to vacate, the tenant has not left the property and has not paid rent. The landlord can file an eviction lawsuit and also compensation for unlawful occupation (ecrimisil) . In Supreme Court rulings, claims relating to the period after the expiration of the contract are considered compensation for unlawful occupation and are therefore accepted as ecrimisil.

7. DUTIES, POWERS AND PROCEDURAL RULES

Certain procedural rules apply in the handling of compensation for unlawful use of property cases before the judicial authorities:

• Competent Court: Since unjust enrichment cases are legal disputes relating to property rights and wrongful occupation, they are heard in the Civil Court of First Instance, which is the general court of jurisdiction, regardless of the amount of the claim . (Unless the case is filed in conjunction with an eviction or lease relationship and according to special procedures in enforcement courts, the general jurisdiction is with the Civil Court of First Instance).

• Competent Court: Since the claim for compensation for unlawful occupation of property relates to the wrongful occupation of the property, the rule of absolute jurisdiction applies according to the Code of Civil Procedure, and the lawsuit in the court of the place where the property is located .

• Burden of Proof: The plaintiff, the property owner, is obligated to prove their ownership rights and that the defendant unlawfully occupied the property. The defendant, on the other hand, must prove that they had a legitimate legal reason for using the property (e.g., a valid contract or consent) or that the conditions for claiming compensation for unlawful use of the property have not been met.

CONCLUSION

Ecrimisil, one of the most functional and protective institutions of property law, is a vital legal instrument that protects the essence of property rights, prevents unjust enrichment of wrongful possessors, and compensates for the economic deprivations suffered by owners. The correct analysis of the existence of unlawful occupation, the requirement for prevention of use, adherence to the five-year retroactive statute of limitations, and the fair calculation of the market value through expert appraisers are critically important for the success of these cases. A correct understanding of the legal limits of the ecrimisil institution directly ensures the just redress of violations of property rights and the establishment of social legal security.
