Nomination of legal representative
For you to deal with us on behalf of an individual or entity, either:
- your client needs to advise us you are representing them
- you can provide written advice of your appointment on your firm's letterhead.
Notification by client
A client can nominate you as their legal representative by:
- calling us on 13 28 66 (for entities) or 13 28 61 (for individuals)
- completing one of the following forms:
Notification by you
If your client has not been able to notify us of your appointment, you are able to provide written proof of your appointment on your firm's letterhead. The letter must contain the:
- firm's letterhead
- client's details, including
- date of birth
- legal representative's details, including
- practice name
- names of authorised legal representative (within the practice) and their contact phone numbers
- purpose of the authorised legal representative’s appointment

For urgent cases, you can phone us to obtain a fax number to notify us of your appointment. An example of an urgent notification of your appointment may be where your client has received a summons to appear in court and you have been appointed late in the process.
It is important to know:
- the fastest way for your client to nominate a legal representative is by phoning us
