How the legal entity transfer to another person's name works?

Good night

I want to know if there is anyone who purchased or sold Amazon account with Ltd. I want to know the procedure.

Thanks.

This entirely depends on whether you are simply changing the legal entity or actually transferring ownership of the business to another person. Amazon generally treats seller accounts as non-transferable when the underlying business ownership changes, in which case the new owner may need their own Seller account.

However, Amazon does have a Legal Entity Change/Transfer Account process for certain situations. Where that option is available, it is normally found under Settings → Account Info → Business Information → Transfer Account, after which Amazon verifies the new entity and its beneficial owners.

I would therefore not simply replace the name, bank details, tax information and identity documents manually, because that can trigger verification or related-account problems. First establish whether this is a change of legal entity with the same ownership or an actual sale/transfer to a different owner, and then follow the process Amazon specifies for that situation.
