1. Defenses That Can Be Developed Against a Lawsuit for Increasing Child Support
When Supreme Court decisions are examined, it is observed that the defenses put forward by defendants against child support increase requests primarily focus on the points that the economic situation has not changed, the payment capacity is limited and the child’s needs are currently being met :< veritable points:
Economic Situation and Financial Hardship: The defendants’ most common defense is that they are experiencing financial hardship (Supreme Court 3rd Civil Chamber-2010/8371 and that no extraordinary change has occurred in their income to warrant an increase in alimony/support (Supreme Court 2nd Civil Chamber-2023/3143 K
New Family and Responsibilities: The defendant’s remarriage, the new spouse not working, or having children from the new marriage, and the existence of education/care expenses for these children are important grounds for defense (Supreme Court 3rd Civil Chamber-2016/12594 K, Supreme Court 2nd Civil Chamber-2024/5549 K).
Existing Debts and Expenses: Financial obligations such as the defendant’s rent payments, consumer loan debts, or retirement due to disability are put forward as a defense (Supreme Court 3rd Civil Chamber-2016/10199 K, BAM Gaziantep 2nd Civil Chamber-2017/1138
Payments Made Apart from Alimony: The defendants have arguments that they voluntarily covered the child’s school, stationery, service, course, and health expenses in addition to the alimony ordered by the court (Supreme Court 3rd Civil Chamber-2016/12594 , BAM Gaziantep 2nd Civil Chamber-2017/1138 ).
Claim of Custody Change: The existence of a lawsuit filed for the change of custody and the temporary custody being granted to the defendant can be presented as a defense that should be made a preliminary issue in the alimony increase lawsuit (Supreme Court 2nd Civil Chamber-2024/984
Secondary Source Note: In secondary sources, it has been stated that in addition to procedural objections such as incorrect declaration of the lawsuit value or insufficient payment of the fee as a defense strategy, claims such as the child actually living with their maternal grandmother or the plaintiff’s economic power being better than the defendant’s can also be put forward (Supreme Court 2nd Civil Chamber-2023/5519 . Furthermore, although it has been argued that filing a new lawsuit before the previous alimony case is finalized constitutes “abuse of right,” the Supreme Court has rejected this defense on the grounds that an alimony increase can always be requested (General Assembly of Civil Chambers-2009/352
2. Appeal Process
It is possible to appeal against the court’s decision to increase the child support. However, this right depends on the decision being above the finality threshold:
Appealability: Parties may appeal against the first instance court’s decisions regarding increases before the Regional Court of Justice (Yargıtay 2. HD-2024/5549 K, HGK-2022/32)
Finality by Amount: If the increased annual alimony amount remains below the legal finality limit on the date of the decision, the appeal application is rejected on the grounds of amount (Yargıtay 2. HD-2025/8820 , Yargıtay 2. HD-2023/5195 . For example, in one decision, the request for appeal was rejected because an annual increase of 6,600 TL remained below the 8,000 TL limit (Yargıtay 2. HD-2023/5195 .
Secondary Source Note: In secondary sources, it has been emphasized that a party who did not appeal the first instance court’s decision regarding child support cannot then appeal the Regional Court of Justice’s decision on this matter (Yargıtay 2. HD-2023/3086
3. Availability of Cassation (Appeal to Supreme Court) and Finality Limits
The right to appeal (cassation) against child support increase decisions is subject to the monetary limits determined according to Article 362 of the Civil Procedure Code (HMK):
Basis of Annual Alimony Amount: In determining appealability (cassation), the 12-month total of the awarded monthly alimony increase (annual alimony difference) is taken into account (Yargıtay 2. HD-2022/1531 Yargıtay 3. HD-2014/15775
Monetary Limits: The finality limits, which vary according to decision dates, are as follows:
72,070 TL for 2020 (Yargıtay 2. HD-2020/2178
78,630 TL for 2021/2022 (Yargıtay 2. HD-2022/1178 HGK-2022/32
107,090 TL for the year 2022 (Supreme Court 2nd Civil Chamber-2022/5407
378,290 TL for the year 2025 (Supreme Court 2nd Civil Chamber-2025/8820 and 544,000 TL (Supreme Court 2nd Civil Chamber-2025/3353
Denial of Appeal: When the annual increase amount falls below these limits, the decisions of the Regional Court of Justice are final, and appeal requests are rejected by the Supreme Court (Supreme Court 2nd Civil Chamber-2025/3353 Supreme Court 2nd Civil Chamber-2023/3143
4. Enforceability of Decisions Before Finalization
In the judicial decisions examined, there is no direct and detailed analysis regarding whether child support increase decisions can be enforced before becoming final. However, some decisions contain the following clues:
Interim Alimony Relationship: In one decision, it was stated that interim alimony would continue until the decision became final, and child support would begin after the decision became final (Supreme Court 2nd Civil Chamber-2023/4022
Hesitation in Enforcement: The defendants have objections stating that alimony increase rates (e.g., PPI increase clause) created hesitation in enforcement (Supreme Court 2nd Civil Chamber-2023/3143
Secondary Source Note: Although a general tendency is observed in secondary sources that alimony decisions, due to their nature, can be enforced through execution before becoming final, no clear legal basis or definitive statement on this matter was provided in the presented documents, and the issue was left ambiguous (Supreme Court 2nd Civil Chamber-2023/3086, Regional Court of Justice İzmir 2nd Civil Chamber-2017/1421

Conclusion: In child support increase cases, defenses are primarily based on financial status; and the avenues for appeal and cassation are available, provided that the annual increase amount exceeds the monetary limits stipulated by law. There is insufficient clear information in documents regarding the execution of decisions before they become final.
