Our firm

Why rebuild a law firm?

In most firms, the hours you pay for go to finding the file, chasing the email and formatting the letter. Here they go to the practice of law.

The problem

A lawyer's day is mostly not law. It is filing, chasing, searching and formatting, and every hour of it is an hour not spent on the case.

What is left is the part that needs a lawyer: reading the whole matter, knowing the law that applies, finding the weaknesses before the other side does, and being candid with you about where you stand.

The firm appears in the Magistrates', County and Supreme Courts of Victoria and is registered with all the VLA panels. The principal is regularly briefed by more than ten Victorian law firms to appear for their clients: a solicitor-advocate with the oral advocacy of counsel and the file already in hand. For a practice of this size, that is possible only because the administration takes care of itself.

How we work

Written here.

Stella does the work that used to fill a lawyer's day: the inbox, the filing, the court diary, the authorities, the first draft. It was written inside the firm by the lawyer who uses it, and Plea Assist, launching 1 November 2026, is built on it. Nothing leaves the office without a lawyer reading it first.
