The deposit sometimes required for specific live sales registration is a bank imprint. It is not a debit but an imprint made by your bank, to which we have no access before the auction.
However, some banks display them as debit on their statements, which is an error. It can activate blockages on your daily, weekly, or monthly payment ceiling.
The deposit will remain untouched if you are not the successful bidder for any lot on Interencheres and will be unlocked immediately after the sale ends. (Some banks may apply a longer release time.)
Please do not hesitate to contact your bank for further information. They might be able to increase your credit card limit if needed.
