Answer
One option is for a person holding a senior position in the
company, such as a director, treasurer or chief executive, to sign
on behalf of the company, Civil Procedure Rules Practice Direction
22.3.4. In addition to signing the statement of truth, the person
must also state their position or role in the company and sign and
print their own name (and not the name of the company they are
signing on behalf of) (CPR PD 22.3.9).
Alternatively, as the company is legally represented, the legal
representative may sign on the company's behalf.
