(1)  A description and designation of the defendant or any other person in a complaint must be sufficient to identify the defendant or other person but does not necessarily have to state his or her correct name, address or occupation.

(2)  Despite subrule (1) , if in a complaint it is impracticable to give a description or designation that sufficiently identifies a person who is not the defendant as required by that subrule, it is sufficient –

(a) to give a description or designation that is reasonably practicable; or

(b) to describe that person as a person unknown.
