My brother deeded moms home in his name 2 years ago when she became ill when she passes is it his or is there anyway family member can stop that or ta

How did your brother do this? Did he forge her name? Did he have her power of attorney? It does not seem proper for him to have done so in any event. You should ask him how he can justify what he has done, and, if he ignores you, you will need to get the courts involved. You should not just wait, but move ahead now if you can, especially if your mom is available and will say she did not want to give him the property.
