The auction takes place via an online bid under the control of the auction committee. Bids are only  possible if the prospective buyer registers in advance and has created a user account via the  website. To this end, the user must provide certain personal details ( name, address (street,  number, postcode, municipality, country), mobile telephone, e-mail address) and indicate whether  he is acting as a private individual or as an entrepreneur. In the latter case, the VAT number must  also be provided. 

The user guarantees the correctness and completeness of the information provided by him, and  undertakes to keep it up to date and to adapt it should the information changes.  After creating the user's account, the user chooses a personal password. 

The user name and password are strictly personal and may not be transferred by the user to third  parties. The registered user is liable for all bids placed via his user name and password. The auction committee reserves the right to refuse the registration of a user account or to  terminate this account.
