Mary Ann was amazing in her approach to finding a resolution in our deceased estate dispute. We had several challenges to contend with including working with a mentally disabled client. Interstate issues and a non complying defendant. Her professionalism, promptness and knowledge all contributed to an outstanding outcome. A big thank you to Mary Ann and her team.

I came to M de Mestre for insight into elder law and the workings of NCAT. They had the experience to answer my questions, explain how things worked, relate it to the merits of my case and discussed potential outcomes, good and bad. My only gripe is that it took me a few days of searching to find them. They are worth speaking to if you have concerns in a similar area.

We had an unfortunate family issue. Mary Ann was recommended. She was fantastic in dealing with the other side. Providing sensible advice and taking the emotion and stress out of how best to move forward.

We had the privilege of working with MaryAnn De Mestre on an estate-related matter, and we truly couldn’t recommend her highly enough. She came recommended to us and from the very beginning MaryAnn was kind, compassionate, and incredibly thoughtful in her approach. She took the time to really listen, making us feel heard and understood throughout a difficult and emotional process. Her communication was outstanding—always responsive and clear and she explained complex legal matters in a way that was easy for us to understand. MaryAnn’s professionalism is matched only by her empathy, and her support made all the difference for us. If you’re looking for a lawyer who combines legal expertise with genuine care for her clients, MaryAnn is the one you want sitting next to you.
