Legal Advice Needed: Property Inheritance and Future Disputes

I'm seeking guidance on the legal process for a property currently under my late father's name. According to a joint will drafted by my parents, this property is to be shared between my eldest and youngest brothers. Since my father's passing in 2022, we've sold another jointly owned property and divided the proceeds among my three brothers. Two brothers received cash payments, while the remaining funds were used to purchase a flat for my eldest brother. This arrangement has been agreeable to all involved parties. However, the property in my father's name remains unchanged, despite the will specifying it should be transferred to my mother and then to me, per her updated will. My mother desires to ensure this property is solely secured for me, given my role as the youngest son and consistent support in covering household expenses. She wishes to avoid any potential disputes or complications involving my siblings or their spouses in the future. What steps should be taken to achieve this goal? Additionally, all marriages occurred within this house. Could any issues arise from my brothers or their wives? Currently, I am residing outside India, while my elder brother continues to reside in the same home with our mother, who prefers not to live alone.
