In Jewish law, a shaliaḥ (Hebrew: שָלִיחַ, [ʃaˈliaχ]; pl. שְלִיחִים, sheliḥim [ʃliˈχim] or sheliah, literally "emissary" or "messenger") is a legal agent. In practice, "the shaliaḥ for a person is as this person himself."[1] Accordingly, a shaliaḥ performs an act of legal significance for the benefit of the sender, as opposed to him or herself.
The term, in contemporary usage, has come to refer more generally to a representative or emissary.
