What customers say

Based on genuine customer reviews

Courtroom advocacy in criminal matters, separation and complex family law disputes, and estate conflicts feature prominently in what clients describe about this practice. Reviewers repeatedly single out Courtney Loffler for her preparation, composure and the way she absorbs the stress of proceedings so clients feel informed and supported at every stage. Her clear explanations and firm but measured approach are credited with favourable resolutions, including in a matter where a custodial sentence was a possibility. Andrew is mentioned in connection with traffic offences, with clients returning to him after earlier representation and describing his expertise and communication as dependable.

Mark is praised for his calm handling of a complex estate matter involving a dishonest executor, where swift and favourable results followed. A theme running through the feedback is the pace at which matters move, from the first consultation through to the final outcome, and clients who have instructed the firm on more than one occasion report consistent results. Thorough preparation ahead of court appearances is a recurring theme, alongside probate issues and family law disputes, with clients noting that their interests were kept central throughout and that each step was explained without jargon.

Mark helped my family with a very stressful situation involving a dishonest executor handling my parents estate. His calm and professional manner was very reassuring and his expertise produced favourable and swift results. I have nothing but praise and no hesitation at all in recommending Mark

After a very difficult separation from my partner of more than nine years, I found myself facing serious criminal charges that carried the possibility of a sentence of up to seven years. At the same time, I was also dealing with a complex family law matter. During this incredibly stressful period, I turned to Williams Barristers & Solicitors at 90 George Street, Thebarton, SA, and I couldn’t have made a better choice. From my very first visit, I was made to feel welcome by the friendly receptionist, which immediately put me at ease. I was then introduced to Andrew, my criminal lawyer. As my case progressed, I nicknamed him “The Tiger” because that’s exactly how he fought for me—determined, fearless, and always focused on achieving the best possible outcome. His professionalism, guidance, and dedication gave me confidence throughout an incredibly challenging time. My family law matter is still ongoing, and Natalia has been exceptional. She has handled everything with professionalism, compassion, and outstanding attention to detail. Knowing she is looking after my case has been a huge source of reassurance. I cannot thank everyone at Williams Barristers & Solicitors enough for their support, dedication, and commitment during one of the most difficult periods of my life. I highly recommend their services to anyone needing experienced and compassionate legal representation.

Saw Stephanie to have a will written up and the process was so easy. I had to reschedule a couple of times due to health issues and had no problems or push back. Stephanie talked me through what everything meant in a way which made sense and left me no doubt that my wishes were reflected appropriately. What is a confronting process felt very effortless and smooth. I also appreciated the empathy and humour.

I can’t thank Courtney Loffler enough for everything she did for me. I walked into court facing a very stressful situation and a possible jail sentence, but thanks to her hard work, preparation, and dedication, the outcome was far better than I could have hoped for. Throughout the entire process she was professional, supportive, and always took the time to explain everything clearly. She genuinely cared about getting the best result possible and fought hard for me when it mattered most. What she achieved has given me the opportunity to keep rebuilding my life, and for that I will always be grateful. I highly recommend her to anyone looking for a lawyer who truly cares about their clients and goes above and beyond.
