Definition

Behalf refers to the support of someone or acting as their representative.

Behalf is used to show that you are doing something for another person or in their interest. It often appears in the phrases "on behalf of" (as a representative) and "in someone’s behalf" (for someone’s benefit). In formal situations, it helps clarify who you are speaking or acting for.

Examples

  • I accepted the award on behalf of my team because they couldn’t attend the ceremony.
  • You shouldn’t apologize on her behalf unless she has asked you to speak for her.
  • He filed the complaint on behalf of his neighbors after repeated disruptions in the building.
  • They negotiated on behalf of the client to secure clearer deadlines and fewer revisions.

Common mistake

Learners often confuse "on behalf of" (as a representative) with "in behalf of" (for someone’s benefit) and use them interchangeably in formal writing.
