The endorser of the acceptance bill should have the seal reserved by the bank.
If you plan to endorse and transfer this acceptance bill, then you can directly stamp it with the seal of the legal representative. Because when the acceptance bill is collected, the bank only verifies the seal of the last endorser. There are no requirements for intermediate endorsements. . .
If you plan to endorse this acceptance bill for collection, then this is not possible in your situation, because the endorsement must be the bank's reserved seal. . . This requires you to provide a certificate with an official seal. For specific proof, you can consult your bank.
Another: If your acceptance needs to be changed, it is best to consult the bank on how to change it first, and do not change it yourself. . . .
If you don’t understand, keep asking! Best wishes~~~
