Kündigungsbutton (§ 312k BGB) / Guide

Cancellation button for Wix: § 312k BGB guide

Do you sell continuing contracts to consumers in Germany through Wix? This guide explains the public cancellation route under § 312k BGB and how to implement it by hand.

Who needs the button?

§ 312k BGB applies to businesses offering consumers paid continuing contracts online, such as memberships, software subscriptions or recurring subscription boxes. The contract matters, not the shop system. Ordinary one-off purchases are outside this rule. Exceptions include financial services and contracts for which the law exclusively requires cancellation in a form stricter than text form.

The law and current BGH position

A legible “Verträge hier kündigen” button, or equally clear wording, leads directly to the confirmation page. Both buttons and the page must always be available and directly and easily accessible. Customers must be able to provide the cancellation type, reason for extraordinary cancellation, identifying details, contract, desired end date and an address for prompt electronic confirmation. The final button says “jetzt kündigen” or an equally clear equivalent.

After submission, the declaration must be savable on a durable medium with its date and time. Immediately confirm electronically in text form, for example by email, including the content, receipt date and time and the end date. Without a specified date, the earliest possible termination applies in case of doubt. A missing statutory cancellation route can allow cancellation without notice.

On 16 July 2026, the BGH held in I ZR 200/25 that retention offers, pause buttons and additional advertising do not belong on the confirmation page. The login cases I ZR 272/25 and I ZR 275/25 were heard on 5 November 2026; judgment is pending. Design a route without a password requirement.

Wix: manual implementation

  • In the Wix editor, create a public cancellation page through Pages & Menu. Allow all visitors and add inputs for the statutory fields. Enable Velo for server-side processing; a general contact form with a success message alone is insufficient.
  • Add a “Verträge hier kündigen” text link to the global footer. Check mobile layouts and pages with hidden footers separately. Use a confirmation-page layout without advertising or retention offers. Publish the changes: editor preview does not prove that the link is reachable on the live site.
  • Have a Velo backend function validate the inputs and store them with a server-generated timestamp in a protected CMS collection. Only backend code should read or write those records. Use a server-side transactional mail service to send the full confirmation immediately to the supplied address; put API keys in Secrets Manager.

Test before publishing

Protect processing against duplicate submissions without requiring login. Offer a downloadable or printable receipt containing the declaration and receipt time; keep sensitive form data out of public URLs. Test the entire route logged out on a phone and check the confirmation inbox. After theme updates, verify the footer link still exists. Disable retention popups on the confirmation page and check caching, cookie banners and maintenance mode. Then process the declaration in the actual subscription system; the form does not stop billing by itself.
