Updated November 2026

Key points

  • Gather every identifier you have
  • Verify identity before contact
  • Approach appropriately, through counsel's plan

What helps

Full name, approximate age, last known address and phone, employer, relatives, and how they relate to the case.

How witnesses are located

Address histories, name changes, employment and associations narrow the search; field checks confirm residence. See witness location.

Contact and interviews

Interviews are voluntary and planned with counsel. Represented witnesses are contacted through their attorneys. See witness interviews.

Unknown witnesses

Canvasses, incident records and camera reviews can identify people who saw an event.

Common questions

What if I only know a first name?

Context, such as a workplace, often allows identification.

Can you serve a subpoena?

Service is handled by appropriate process servers once the witness is located.

How quickly can a witness be found?

Many within days; harder cases take longer.
