A rent determination lawsuit is a type of legal action filed to adjust the rental amount in accordance with current economic conditions and comparable market rental values. In long-term lease agreements, when the rent falls below market levels, a rent determination lawsuit may be initiated.

Under the Turkish Code of Obligations, a rent determination lawsuit may be filed under certain conditions. In particular, in lease relationships that have lasted for five years or more, or in lease agreements renewed after five years, the court may be requested to determine a new rent amount based on comparable market rental values.

The timing of filing a rent determination lawsuit is of significant importance. If a notice is served or the lawsuit is filed at least thirty days before the start of the new rental period, the court’s decision may apply to that rental period. Therefore, correct timing of the lawsuit is crucial to avoid loss of rights.

Property owners or tenants in Bandırma who are considering filing a rent determination lawsuit should obtain a legal assessment before initiating proceedings in order to ensure that the process is conducted more effectively.
