Class actions allow one person who has a claim to commence court action on behalf of groups of people who have the same claim. 

This means that those people can combine their resources to pursue a claim that would be too expensive for just one person.

At ACA Lawyers we take this a step further, working with litigation funders to run class actions at no risk to you or the group. This means that we can run class actions on a 'no win, no fee' basis.


ACA Lawyers uses experience, technology and innovation to provide commercial law, commercial litigation and commercial class action services. Our approach means that we can provide better outcomes at lower cost.

As part of our commitment to you and to demonstrate our confidence in the legal services we provide, we risk-share our costs on all of the class action on which we are retained.

The ACA Lawyers team is made up of highly experienced lawyers who have worked for some of Australia’s leading law firms. Every one of us is flexible, accessible and collaborative, and we are focused on achieving the outcomes you want to achieve.

Our cost-effective approach matches appropriate legal resources to each matter, adding or reducing legal resources to meet the changing demands of litigation. We won’t weigh a case down with a costly army of solicitors, junior and senior counsel; we stick to streamlined, highly skilled and experienced teams of legal professionals.
