All auction proceedings are verified by independent notary official mr. J. Borren of mr M.J. Meijer Notarissen N.V., Amsterdam.
Sellers are not permitted to place bids on their own submissions. To that end, our system ensures that sellers are unable to place bids on items submitted using their own accounts.
For all of Catawiki's auctions, if a bid is placed in the last minute, the bidding window is automatically increased by 90 seconds. This gives other bidders enough time to place a counter-bid and you won't be required to wait till the final seconds start ticking away before placing your bids. Catawiki always provides a clear indication of which bidder placed the highest or winning bid. All winning bidders receive a confirmation email indicating they've won as soon as the auction ends.
Catawiki employees and/or their family members are not allowed to submit items for auction at Catawiki. This helps guarantee the neutrality of our employees when dealing with our auctions. Catawiki sees to it that this rule is strictly enforced.
- Experts are not allowed to place bids.
If users wish to sell objects on Catawiki, they may be asked for a scan or photograph of a valid proof of identification (government-issued photo ID). The information on the proof of identification, which clearly shows at least the full name, date of birth and ID (document) number, is required by our third party payment processor, Stripe, that processes payments on our online platform.
