Legal Definition
A counterparty is a party to a contract or legal agreement, typically the other party in a transaction or dispute. In legal contexts, it refers to another entity (person or entity) with whom a legal obligation exists, often involving obligations under a contract or legal claim.
Plain-English Translation
Imagine two people who are signing up for a deal or lawsuit together; one person is the 'counterparty' because they are the other side of the agreement. It means the other person in a legal situation, like another company or individual involved in a contract.
