Update the contact information associated with the domain name (supporting documents)

Update 10/19/2026

This guide is intended for users who are unable to validate the WHOIS ownership change via the standard procedure (❓: help) by email (outdated or inaccessible email address, death, etc.).

 

Introduction

  • To protect the legal owner against domain hijacking or theft, Infomaniak never makes manual changes to WHOIS contact information without formal authentication and identity verification.
  • Domain-related hosting services are not affectedusing this procedure: they remain linked to the Infomaniak customer account to which they belong.

 

Documents to send to support

Contact Infomaniak support by email, specifying the domain concerned and providing scanned copies of the supporting documents relevant to the current owner's situation:

To avoid delays: ensure that the signature on the letter is strictly identical to that on the identification document (which must be valid) and that the official documents are recent.

  2. Front and back copy of a valid ID (identity card or passport).

2. Association

  2. Latest minutes of the general meeting (from the current or previous year) confirming the election or position of the president.

  2. Recent excerpt from the commercial register.
  3. Front and back copy of the authorized signatory's ID.

Note: In the case of a collective signature (e.g., "collective signature by two"), please provide the IDs of all required signatories and, if applicable, the official power of attorney.

  1. Letter drafted and signed by the business owner.

Special cases

  • Domain managed by a third party (service provider/agency):if the service provider has registered as the WHOIS owner, the domain legally belongs to them. Infomaniak will only be able to process your request if it comes from the owner identified in the WHOIS or in the event of a court decision.
  • Extensions with specific rules (e.g. .de, .pt, .be, .es): depending on the registry, dedicated registry forms or double agreement on a third-party platform may be required in addition.
