Canton TG
In Thurgau each municipality sets the customary dates: some use 31 March, 30 June and 30 September (e.g. Frauenfeld, Weinfelden), others any month end except 31 December (e.g. Kreuzlingen, Arbon, Amriswil). The notice dates in your lease take precedence over customary dates; the notice period for flats is at least three months (Art. 266c CO).
| Area | Dates | Note |
|---|---|---|
| Municipalities with quarterly dates | 31.03. · 30.06. · 30.09. | E.g. Frauenfeld, Weinfelden, Eschlikon, Sommeri, Roggwil. |
| Municipalities with month-end dates | any month end | Any month end except 31 December, e.g. Kreuzlingen, Arbon, Amriswil, Münchwilen, Sirnach, Tägerwilen. |
The termination dates in your lease always take precedence. For flats the notice period is at least three months (Art. 266c OR).
For a lease in Frauenfeld without its own termination dates, our calculator currently works with 31.03. · 30.06. · 30.09.. The next reachable date: send the request by 26.12.2026, and the lower rent applies from 01.04.2027.
Where termination is possible at more dates, we deliberately use a conservative subset so that no request is sent too late.
Municipal conciliation authorities for tenancy
In Thurgau each municipality or group of municipalities has its own conciliation authority for tenancy (e.g. the towns of Frauenfeld, Kreuzlingen, Arbon). The authority where the flat is located is competent; the canton publishes a directory, and requests can also be filed electronically. Conciliation in tenancy matters is free of charge (Art. 113(2)(c) Swiss Civil Procedure Code).
Official information and addresses
Tenants have 30 days to file after a refusal or after the landlord's 30-day answer window has passed (Art. 270a para. 2 OR). See what to do if the landlord refuses.
