U.S. legal term

assignor

The assignor is the party who transfers rights, interests, or obligations to another party, typically in a legal context such as a contract or legal claim.

Imagine you have a right to something (like a right to collect money from someone), and you decide to hand that right over to another person. The assignor is the person who starts the process of giving that right away.

It matters because it clearly establishes who holds the original right or obligation being transferred within a legal document, such as a deed, a contract assignment, or a litigation claim. It defines the starting point of the delegation of rights.
