If it is the signature of receiving goods, you should also write your own name, indicating that it is receiving goods on behalf of others. If you write someone else's name directly, you are forging your signature.
In daily life, the most common behavior of signing for mail and parcels includes the responsibility of signing and keeping. According to the relevant regulations, once the mail is signed for others, the signing contract relationship between the signing agent and the buyer is formed, that is, the signing agent immediately plays the role of the custodian. During the storage period, if the deposit is damaged or lost due to improper storage by the custodian, the custodian shall be liable for damages. However, the custody is free of charge, and if the custodian can prove that he has no gross negligence, he may not be liable for damages.
