Siobhan Mullins, Separate Together

Siobhan MullinsAuthor | Divorce Consultant (Lawyer) | Founder of Separate Together

Siobhan is a bestselling author and is a collaboratively trained and award winning divorce lawyer. Siobhan is also the founder of Australia's leading online family law firm, Separate Together.

Launched in May 2017, Separate Together specialises in DIY divorce and separation, breaking down the process of what needs to happen to make the separation official, including any separation agreements. 

The firm has been named a Leading Innovative Firm by Australasian Lawyer (2019) for its integration of technology (document automation and previous AI), its plain English handbooks, instructions and unique approach to the practice of family law. 

Siobhan’s goal is to have relationship breakdown no longer identified as one of life’s top seven stressful events, by changing the way that people can experience the legal separation and divorce process.

Clients who have worked with Siobhan or have used Separate Together's services describe the experience as “easy”, “less stressful” and “simple”.
