nonofficial

Lacking formal authority

Nonofficial means not holding or connected with an official position or capacity.

A nonofficial source lacks institutional authority; a nonofficial visit happens outside formal diplomatic channels.

The word often distinguishes private actions from those taken in an official role: She attended in a nonofficial capacity.

Interchangeable with unofficial in most contexts.
