Help Secure Justice for a Mother's Estate

My mother passed away the 25th of June and I unfortunately need legal help to take care of her estate that she was manipulated into signing over while she was sick, she had no memory of the incident. I never ask for help of any kind and this is very difficult for me. In 2022 her youngest son produced a quit claim deed to her property and accounts with a signature similar to hers but not exact and had someone noterize it. She had no knowledge of it. So long story short, the last year of her life was spent with heartache and stress knowing her youngest son would do such a thing. We've been dealing with the courts on the matter but I need to obtain a quality lawyer for help. Thank you
