Interpreting is translation's real-time sibling, and the risk profile changes with the tense: no revision pass, no translation memory, just live rendering in courtrooms, hospitals, police interviews and asylum tribunals where a misrendered phrase can shape an outcome.
Insure the spoken word's specific risks: confidentiality, conduct-code breaches, and the premises you work on. Check whether agency and framework contracts cover you or merely require you to be covered – usually the latter – and if you also translate documents, one linguist policy should name both activities (see our translator guide for the written-work specifics, including machine-translation sign-off).
