Armstrong Legal is an Australian law firm specialising in criminal law,
traffic law, corporate crime and family law.

We have been providing advice and assistance to people needing help with family and criminal law matters since the founding parters Peter Magee and Lionel Rattenbury purchased the practice in August 2002. 

The firm has grown very rapidly over this period and boasts three accredited specialists in criminal law and family law. We now have offices in Sydney, Parramatta, Miranda, Wollongong and a family law office in Canberra.

Peter and Lionel have founded the firm on the Christian values of integrity and compassion.  They believe that much of the success of the firm is based on the high level of service given to their clients. 

"We believe that in our field, knowledge and expertise is essential. For this reason we only accept cases within the areas of criminal law, traffic law, corporate crime and family law." says Lionel.

The staff of Armstrong Legal are focused on achieving our motto "Service with Excellence".
