Pronunciation: [ɪndˈɔːsə] (IPA) 
The word "Indorsor" is spelled with an "i" and a "s" in place of the more common "e" and "c" found in the word "endorser." The pronunciation is the same for both spellings, however, the IPA phonetic transcription would be /ɪnˈdɔːsə/. Both spellings are acceptable; the "i" and "s" spelling is commonly used in legal contexts and in British English, while "e" and "c" is more widespread in American English.
An indorser, also spelled as "endorser," is an individual or entity who signs their name on the back of a negotiable instrument, such as a check or promissory note, to transfer ownership rights or to guarantee payment. The act of signing on the back of the instrument is known as endorsement. By endorsing the instrument, the indorser assumes liability for its payment, making a promise to pay the amount specified on the instrument to the subsequent holder, if the original issuer fails to do so.
The indorser can be an original party to the instrument or a subsequent holder who transfers it to another party by endorsing it. This transfer of ownership rights through the indorsement allows the instrument to be traded or negotiated freely in the marketplace.
The indorser's signature on the instrument serves as proof of their consent and acts as a certification of its authenticity and validity. It is essential for the indorser to clearly indicate their intention to transfer the instrument by including words such as "pay to the order of" or "without recourse." Failure to properly indorse the instrument may result in difficulties in negotiating or enforcing it.
Indorsers play a crucial role in the functioning of negotiable instruments, as their endorsement helps establish the chain of ownership and ensure the smooth flow of transactions in the economy.
The word "indorsor" is derived from the term "endorse", which originated from the Medieval Latin word "indorsare". "Indorsare" itself comes from the Latin phrase "in dorso", meaning "on the back". In the context of the word "indorsor", it refers to a person who endorses or signs the back of a negotiable instrument, typically a check, transferring the rights to someone else.
