Legal deadline calculatorAppeal (istinaf), appeal on points of law (temyiz), administrative case and deportation deadlines in Turkey

1.How are deadlines calculated?

To calculate a legal deadline, first determine the date on which the period starts, i.e. the date of service. Article 92 of the Code of Civil Procedure (HMK) and Article 8 of the Administrative Procedure Law (İYUK) set out the same principles:

• For periods set in days, the day of service is not counted; the period starts on the following day. For a 7-day period, if service took place on the 10th, the last day is the 17th.
• Periods set in weeks end at the close of working hours on the corresponding day of the last week. The 2-week appeal period for a decision served on a Wednesday ends on the Wednesday two weeks later.
• Public holidays are included in the period. However, if the last day falls on a holiday, the period ends at the close of working hours on the first working day after the holiday (HMK Art. 93).
• The deadline is peremptory. As a rule, a missed deadline cannot be remedied; in the cases provided by law, restoration to the previous state (eski hâle getirme) may be requested.

2.Main lawsuit and appeal deadlines

These are the deadlines foreigners encounter most often; the legal deadline calculator covers all of them:

• Lawsuit against a deportation order: 7 days from service.Law No. 6458 (YUKK) Art. 53/3. As a rule, filing the lawsuit suspends enforcement of the order.
• Administrative case: 60 days from service (30 days in tax cases).İYUK Art. 7. Filed against acts such as refusal of a residence permit, refusal of a work permit or an entry ban.
• Appeal (istinaf) and appeal on points of law (temyiz) in administrative courts: 30 days.İYUK Art. 45 and 46.
• Appeal (istinaf) and appeal on points of law (temyiz) in civil cases: 2 weeks.HMK Art. 345 and 361. The period starts from service of the reasoned judgment.
• Statement of defence: 2 weeks.HMK Art. 127.
• Appeal (istinaf) and appeal on points of law (temyiz) in criminal cases: 2 weeks.CMK Art. 273 and 291; under Law No. 7499 (2024), the period is two weeks from service of the reasoned judgment.
• Objection to a payment order: 7 days.İİK Art. 62.

3.Deadlines with e-Tebligat

Under Article 7/a of Notification Law No. 7201, electronic service is deemed effected at the end of the fifth day after the notification reaches the recipient’s electronic address. Opening the notification earlier does not change this date. In a 2025 decision, the Constitutional Court did not find this rule unconstitutional.

If you tick the “e-Tebligat” box in the calculator, the date you enter is taken as the date the notification arrived, and the period starts 5 days later. Since service on foreigners who have a UETS address can be made electronically, this rule deserves particular attention.

4.Public holidays, eves and judicial recess

• Public holidays and weekends: If the last day falls on a Saturday, Sunday or public holiday, the period is extended to the next working day. The calculator includes the public holidays of 2026 and 2027.
• Eves (half day): The eves of Ramadan Feast and Feast of Sacrifice and the afternoon of 28 October are holidays. Since in practice the period is not deemed extended, it is safer to act before 13:00 if the last day falls on an eve.
• Judicial recess (20 July – 31 August): In matters subject to the judicial recess, periods falling within the recess are deemed extended from the end of the recess by 1 week in civil cases (HMK Art. 104), 7 days in administrative cases (İYUK Art. 61) and 3 days in criminal cases (CMK Art. 331). No extension applies to matters not subject to the recess, such as detention matters and urgent matters.

If it is unclear whether a matter is subject to the judicial recess, the safest course is to rely on the earlier date without counting the extension. Details: litigation for foreigners in Turkey.
