In the event of a transfer of risk, the responsibility is transferred to another party via a delivery. This point in time at which the transfer takes place is very important for the transfer of risk and for the sending of goods. The transfer of risk occurs in commercial sales only when the recipient receives the package at his front door. Thus, the dealer is obliged to provide for a new delivery, if it has come to a transport damage or no delivery. In order to check the delivery, the parcels can often be closely tracked on their delivery route. In the case of private individuals, the transfer of risk takes place with the handover of the goods to a parcel service.
