Do owners or notaries need to be present to bid for the goods sold by property owners?

The property has no right to sell the owner's goods unless the court enforces it and entrusts the property to be sold publicly, usually by auction.

If it is a tender for goods, it belongs to the owner's personal entrustment and needs a notarized power of attorney to sell it. If it is entrusted by the court, you need to go through the relevant procedures.

Individuals sell their own goods without notarization, and the entrusted auction is conducted according to the contract and the power of attorney in the absence of the owner.
