Whose responsibility did the courier lose halfway?

Legal analysis: the courier company failed to deliver the goods to the designated consignee, and its behavior itself was a breach of contract.

1. The courier company cannot submit evidence to prove that the loss of the express mail was caused by the consignee's fault and should be liable for the loss of the goods.

2. If the courier is lost after being signed by the property agent, the recipient has agreed to sign the courier for the residential property, and the courier company will not be responsible. The property company collects the parcel with the consent of the owner, and the owner himself will bear certain responsibilities if there is any problem with the parcel.

Legal basis: Article 897 of the Civil Code of People's Republic of China (PRC). During the storage period, if the deposit is damaged or lost due to improper storage by the custodian, the custodian shall be liable for compensation. However, if the unpaid custodian proves that he has no intention or gross negligence, he shall not be liable for compensation.
