Also, it's helpful to familiarize yourself with the terms you may encounter: the payee is the person with the check; If he endorses it (transmits his right to collect it) to someone, he becomes the endorser and that third person, the endorsee. Furthermore, a bearer check is one that can be cashed by whoever has it, while if it is nominative it is intended for a specific person or company. How to cash a check: time frames, ways to receive the money and when they will charge you a commission To endorse a check and, therefore, transmit all its rights, "the endorsement must be written on the check or its supplement and will be signed by the endorser," states the Foreign Exchange and Check Law in Chapter II. The endorsement may be blank (bearer) if the original payee of the check puts his or her signature on the back.
If you want to transmit it to a specific person, you will have to add their first and last name , as well as some other identifying information, such as their ID. This person, in turn, can endorse the check to another... unless the endorser has prohibited it. In the following Asia Phone Number List image (from HSBC bank), you can see an example of how to endorse a check, although in the simplest cases of endorsed checks it will be enough for the signature of the original beneficiary to appear, or their signature and the name of the person to whom who transmits it. This is how you can endorse a bank check, but there are some limitations: not all checks can be endorsed (only if it is bearer or nominative.

Unless it includes the 'not to order' clause) and whenever it is done it will be transferred by the total amount (you cannot endorse part of the check). Regarding the first point, the rule makes it clear that "the check issued in favor of a specific person with the clause not to order or another equivalent is not transferable except in the form and with the effects of an ordinary assignment." Regarding the second aspect, it points out that "the endorsement must be total, pure and simple" and insists that "the partial endorsement and the one made by the drawee" (the banking entity) are void.
