What Do You Call Someone Who Is Being Represented? [duplicate]

Assume Joe is sent to represent Sarah in a meeting. What would Sarah be to him? I'm looking for a more informal context, so it wouldn't be a client.


It's considered archaic, but there's always representee.

From Collins:

representee
(ˌrɛprɪzɛnˈtiː)
NOUN
1. (in contract law) a person to whom a legal representation ( statement of fact concerning a contract) is made
2. archaic: a representative, esp in a parliament
3. archaic: a person who is represented
