The Problem of Determining the Starting Date of Interest in Enforcement Proceedings Based on a Court Order

Determining the starting date for interest accrual in enforcement proceedings based on a court judgment is a far more critical issue in practice than is commonly perceived. This is because in most cases, the dispute is no longer about whether or not there is an actual debt, but rather about the date from which the judgment accrues interest and which date should be considered in the enforcement order. Especially if the type of interest or the starting date is not explicitly stated in the court decision, the line between the creditor's attorney's request for enforcement and the debtor's attorney's complaint of "inconsistency with the judgment" becomes very delicate. Therefore, the issue of the starting date for interest accrual in enforcement proceedings based on a court judgment is not merely a matter of calculation; it is directly related to the scope of the judgment, the enforcement officer's authority, and the enforceability of the judgment.

The problem stems from the intersection of two distinct legal fields. On one hand, there are the rules of substantive law that determine the date on which a debt defaults and the date from which default interest accrues; on the other hand, there are the rules of enforcement law that determine the extent to which the enforcement office must adhere to the judgment during its execution. Article 117 of the Turkish Code of Obligations adopts, as a rule, the system of default by notice for due debts; the same article states that in tort cases, default arises on the date the act is committed, and in unjust enrichment cases, as a rule, on the date the enrichment occurs. Article 120 of the Turkish Code of Obligations stipulates that, unless otherwise agreed upon in the contract, the applicable annual default interest shall be determined according to the legislation in force on the date the interest obligation arises. In contrast, in the enforcement phase of a judgment, according to Article 32 of the Enforcement and Bankruptcy Law, the enforcement order is issued based on the type and amount of the thing awarded in the judgment; that is, the enforcement officer cannot expand upon the judgment or establish a new provision.

For this very reason, the starting date for interest in enforcement proceedings based on a court judgment is not always the earliest possible date under substantive law. During the litigation phase, the creditor may have requested interest from the date of default, the date of the notice, the date of the tort, or the date of the lawsuit; and the court may rule accordingly. However, after the judgment phase, what is decisive is not only the legal nature of the claim, but also what the judgment clause states. As emphasized in the summaries of the Supreme Court's General Assembly of Civil Law decisions, if the judgment clause of the enforcement proceedings contains a section relating to interest, it must be calculated in accordance with the judgment; the type of interest may be legal interest, commercial default interest, or non-commercial default interest, depending on the nature of the claim and the decision in the lawsuit. This approach clearly shows that the enforcement officer cannot override the judgment clause.

If the interest commencement date is clearly stated in the judgment

This is the least likely scenario. If the court has specified a clear starting date in the judgment clause, such as "from the date of the lawsuit," "from the date of default," "from the date of notification," "from the date of the tort," or "from the date of enforcement," then interest in enforcement proceedings based on a judgment starts from that date. The enforcement officer does not have the authority to change, advance, or retract this date, or to create a new starting date for interest by saying, "legally, another date would have been more correct." Since Article 32 of the Enforcement and Bankruptcy Law stipulates that the enforcement order shall be issued according to the judgment, the essential factor here is not the "most materially correct date," but the "date stated in the judgment." The summaries of Supreme Court Grand Chamber decisions also agree, accepting that if there is a section regarding interest in the judgment clause, it must be applied in accordance with the judgment.

The practical consequence of this rule is that even if the court mistakenly sets a later interest accrual date, this error cannot be corrected in the enforcement file; it must be corrected through legal action or an appropriate procedural application. The reverse is also true; if the court sets an earlier date, the debtor cannot raise the claim that "this date is not actually in accordance with substantive law" as a simple objection to the calculation in enforcement proceedings. This is because the enforcement office is not an authority that conducts retrials. In this respect, the interest accrual date in enforcement proceedings is one of the areas where the principle of the binding nature of the judgment becomes very visible.

If interest is mentioned in the judgment, but the starting date is not explicitly stated

The crucial point in practice arises here. The judgment may simply state "to be collected with interest," but not specify from what date the interest will accrue. In this case, the enforcement officer cannot freely choose a date. According to the Supreme Court's practice reflected in the case summaries, if the judgment underlying the enforcement proceedings does not contain a provision regarding the commencement date of interest, it is generally accepted that interest can be claimed from the date of the judgment. Similarly, the case summary in e-Uyar states that if the judgment does not specify the commencement date of interest, interest can be claimed from the date of the judgment, but this date changes for judgments that need to become final.

This result may seem surprising at first glance. Because, from a substantive law perspective, the debt may have already been in default. However, if the court decision does not specify the starting date for interest, a new default analysis cannot be conducted and the judgment expanded during the enforcement phase. In other words, it cannot be said, "If the court is silent, the enforcement officer should go back to Article 117 of the Turkish Code of Obligations and find the date of the warning." The enforcement officer is not an authority that fills a judicial gap. Therefore, in practice, judgments without specifying the starting date for interest, especially in high-value commercial cases, create a significant risk of interest loss or, conversely, excessive enforcement contrary to the judgment.

Article 305 of the Code of Civil Procedure (HMK) is also important here. The text of the HMK published by the Ministry of Justice explicitly stipulates that parties may request clarification if the judgment is not sufficiently clear or if it raises doubts regarding its execution. Therefore, in the face of a judgment with an uncertain interest commencement date, the most sound approach, depending on the nature of the case, is to evaluate the possibility of clarification rather than directly initiating disputed enforcement proceedings. Clarifying the judgment is often a safer strategy than filing a complaint of "inconsistency with the judgment" in the enforcement file.

In judgments that cannot be enforced before they become final, from what date does interest begin to accrue?

One of the issues that most complicates the problem of the starting date for interest in enforcement proceedings based on a judgment is the judgments that require finality. Article 367 of the Code of Civil Procedure states that, as a rule, an appeal does not suspend enforcement, but judgments relating to personal law, family law, and real rights related to immovable property cannot be enforced until they become final. The same system is maintained in Article 350 of the Code of Civil Procedure for appeals. This structure makes it necessary for some judgments to become final in order to be enforceable, even if a judgment has already been rendered.

In this case, the general rule regarding the commencement date of interest also changes. In the summaries of Supreme Court decisions, it is stated that if there is no specific provision in the judgment regarding the commencement date of interest, interest can be claimed from the date of the judgment; however, in cases where the judgment must become final for execution, the ancillary claims included in the judgment also become due and payable upon finalization, and interest should be calculated from the date of finalization. This acceptance is particularly important in cases concerning the ownership of immovable property, especially regarding attorney fees and court costs. In practice, the creditor only considers it an "ancillary claim" and charges interest from the date of the judgment; the debtor, on the other hand, raises this as a complaint of inconsistency with the judgment. The prevailing view is that if the main judgment cannot be executed before it becomes final, the commencement date of interest on the ancillary claims should, in most cases, be linked to the date of finalization.

This leads to a very practical conclusion regarding the commencement date of interest in enforcement proceedings based on a court judgment: the date of the judgment is not the basis for each case for the same monetary item. First, the following question must be answered: "Can this judgment be enforced before it becomes final?" If the answer is no, then the commencement date of interest is often the date of finalization, not the date of the judgment. Enforcement proceedings initiated without making this distinction become open to serious procedural objections, especially in cases concerning the cancellation and registration of title deeds, family law, and personality status.

Differences in judgments regarding delivery and performance obligations

The issue of the interest commencement date is not limited to monetary judgments. In judgments concerning the delivery of movable property, specific performance, or payment in lieu of delivery, the commencement date of interest requires particular attention. Especially under Article 24 of the Enforcement and Bankruptcy Law, if the movable property to be delivered is not in the debtor's possession, valuation and payment collection may become relevant. In such cases, Supreme Court decision summaries indicate that if the judgment does not specify the interest and commencement date, the date the debtor was put in default will be taken as the basis; and that interest can be claimed from the date of notification of the notice sent to the debtor for the value determined by the enforcement office in accordance with Article 24 of the Enforcement and Bankruptcy Law.

This approach also explains why a different conclusion can be reached compared to the "date of judgment" rule in monetary judgments. Because here, the judgment does not directly concern a specific monetary debt; rather, it primarily addresses a delivery obligation, with the price determined later or shaped during the enforcement process. Therefore, the commencement of interest is linked not directly to the date of the court decision, but to the notification during the enforcement phase where the debtor is found to be in default regarding payment. In other words, in delivery judgments, the commencement of interest is sometimes determined not by the court judgment, but by the memorandum during enforcement. Therefore, applying the same interest calculation template to every judgment-based enforcement file is not legally correct.

Confusing the starting interest rate and the type of interest in commercial transactions and foreign currency receivables

A common mistake in practice is confusing the interest commencement date with the interest rate or type. According to Article 2 of Law No. 3095, a debtor who defaults on a payment of a sum of money shall pay default interest for the past days at the rate specified in Article 1, unless otherwise agreed in the contract; in commercial transactions, if the rate applied by the Central Bank of the Republic of Turkey for short-term advances on December 31 of the previous year is higher, that rate may be applied. Article 4/A of the same law also provides for a special interest regime for foreign currency debts. On the other hand, Article 3 of Law No. 3095 generally prohibits compound interest. These provisions determine the type and rate of interest; however, they do not alone determine the interest commencement date. The commencement date, the rate, and the type of interest are separate.

This distinction becomes even more important in enforcement proceedings based on a court judgment. Because in some cases, lawyers choose the correct start date but apply the wrong type of interest; in other cases, they choose the correct type of interest but apply it from the wrong date. The Supreme Court's General Assembly decision summary also states that the interest in question, depending on the nature of the judgment, can be legal interest, legal commercial default interest, or non-commercial default interest. Therefore, for the correct outcome in enforcement proceedings based on a court judgment, three separate questions must be answered simultaneously: Is there interest? If so, from what date does it start? And what type/rate is applied? Answering only one of these three questions correctly is not sufficient.

Current interest rates should also be carefully considered. The consolidated text of Law No. 3095 indicates that, under Article 1, an annual rate of 24% will be applied starting June 1, 2024. However, this rate is only a starting point for the "legal interest rate"; the case may be a commercial transaction, involve a foreign currency debt, or the judgment may have directly awarded a different type of interest. Therefore, the approach of "currently the legal interest rate is 24%, therefore this rate applies to every enforcement proceeding based on a judgment" is incorrect.

Starting interest on attorney fees and court costs

In enforcement proceedings based on a court judgment, a significant portion of the debate over the starting date of interest stems not from the principal debt itself, but from ancillary items such as attorney fees and court costs. While these items may be listed in the court judgment, a specific date for interest accrual may not be stated. Case law summaries indicate that if the judgment does not specify a starting date for interest accrual, the date of the judgment can be taken as the basis; however, in cases where the judgment cannot be enforced before it becomes final, interest accrues from the date of finalization for these items as well. Therefore, automatically applying "interest from the date of the judgment" for attorney fees and court costs is not reliable in every case. The finalization regime of the judgment must first be determined.

Furthermore, it is important to determine which type of interest these items are subject to in the judgment. In the summaries of the Supreme Court's General Assembly, it is stated that the nature of the interest will be determined according to the nature of the claim and the decision in the case. This shows that even in the interest of ancillary claims, one should not proceed with the assumption of a "uniform legal interest rate." If the case arises from a commercial transaction, the wording of the court's judgment and the claim upon which it is based should be read together.

Conclusion

The issue of determining the starting date for interest in enforcement proceedings based on a court judgment, while seemingly a technical calculation problem at first glance, actually involves a delicate balance between the scope of the judgment, the rules of default, the finality regime, and the principle of adherence to the judgment. For a sound solution, the following sequence should be followed: First, it is checked whether the interest and the starting date are clearly stated in the judgment clause. If they are, the discussion ends; whatever the judgment says is applied. If not, the rule of the date of the decision comes into play; however, if the judgment cannot be enforced before it becomes final, then the date of finality is taken as the basis. In special enforcement regimes, such as judgments delivered by hand, default may sometimes arise with a memorandum during the enforcement phase. In the final stage, the type and rate of interest to be applied to the chosen date are determined separately.

Therefore, the safest approach in practice is to read the judgment clause not only in terms of the "amount to be collected" but also separately in terms of "the existence, type, and commencement date of interest" before initiating enforcement proceedings. If the judgment is unclear, clarification should be considered; if a condition of finality exists, the enforcement strategy should be established accordingly; and distinctions between commercial transactions, foreign currency debts, and ancillary claims should not be neglected. Otherwise, a seemingly minor error in the interest date can render the accrued interest amount, which constitutes a significant part of the case, legally disputed and alter the course of the enforcement proceedings due to a complaint of non-compliance with the judgment. True expertise in enforcement proceedings based on a judgment lies not only in putting the judgment into execution but also in correctly interpreting from what date and how the judgment accrues interest.
