Legal Tools and Document Checklists
Use practical document, deadline and remote-instruction checklists before requesting an assessment of a legal matter in Turkey.
These practical checklists help international clients organise documents before contacting the office. They are informational and do not calculate a final deadline or legal entitlement.
Document preparation checklist
Prepare a clear timeline, contracts, invoices, payment records, court or enforcement documents, correspondence and the identity details of the parties.
Remote instruction checklist
State where you are located, whether an original document is available and whether notarisation, apostille, sworn translation or a power of attorney may be required.
Urgent deadline check
If a notice, judgment, payment order, detention or removal decision has been served, include the exact service date. Do not rely on this page to calculate a procedural deadline.

What is the legal interest rate for 2026?
With the 2026 amendment to Law No. 3095, the statutory interest rate was linked to the short-term rediscount rate of the Central Bank of the Republic of Turkey instead of a fixed rate. Based on 80% of the 38.75% rediscount rate that came into effect on December 20, 2025, the annual statutory interest rate is 31% from July 31, 2026. In the previous period, an annual rate of 24% was applied from June 1, 2024 to July 30, 2026.
| Period | Annual rate | Automatic application |
|---|---|---|
| January 1, 2006 – May 31, 2024 | %9 | Yes |
| June 1, 2024 – July 30, 2026 | %24 | Yes |
| July 31, 2026 – December 31, 2026 | %31 | Yes |
How is legal interest calculated?
In simple interest calculation, the principal amount, annual interest rate, and number of days are considered together. The interest calculator on this page calculates each statutory interest period separately with its own rate if the selected date range falls within more than one period, and then sums the results. For example, if the start date is 2024 and the end date is 2026, the days falling under 24% and 31% will appear in separate rows.
The “Special annual interest rate” option is for trying a rate specified in the contract or a rate determined separately for your case. In commercial transactions, default interest, labor interest, public debt late payment penalty, and foreign currency debt may not be subject to the same rules.
Frequently asked questions about legal interest and default interest
Are statutory interest and default interest the same?
Statutory interest is the rate determined by law when no rate is specified in the contract. Default interest arises due to the failure to pay the debt on time. While rates may coincide for general debts, different rates may apply to commercial transactions and receivables under special laws.
Does the calculation include the starting day?
The number of days is found by including the end date but excluding the start date of the vehicle. If a court decision, enforcement order, or the wording in the contract requires a different interpretation, the dates should be evaluated accordingly.
Can commercial default interest be calculated?
If you know the applicable annual rate for your file, you can perform the calculation using the “Special annual interest rate” mode. Commercial classification and the applicable rate may require legal review.
Why is it not automatically calculated for 2027 and beyond?
In the new system, the rate may change periodically according to the CBRT rediscount rate. To avoid assuming a rate that has not yet been finalized, the automatic calculation is limited to December 31, 2026.
