IPA: /ˈʧæmpərti/
KK: /ˈʧæmpərti/
An agreement where a person who is not involved in a lawsuit helps to support it in exchange for a share of the money won from the case.
The lawyer entered into a champerty agreement to help the plaintiff with the lawsuit.
Champerty originates from Old French 'champart' (meaning a share of the profits), which is derived from 'champ' (meaning field) and 'partir' (meaning to divide). The term refers to an agreement where one party provides financial support for a lawsuit in exchange for a share of the proceeds.
Think of 'champ' as a field where profits are 'divided' ('partir') — champerty is about sharing the profits from a legal case.
