ownership of family owned property

[Phillip James]

I had a potential client who said his brother had their mother sign the deed of the family owner house over to him while their mother was dying of breast cancer.  The family also owner property in other areas of the state.  This person did not know if their mother signed all of the properties over to his brother, however, he did tell me that his brother does not have the financial means to care for the properties. This person is therefore, concerned that the family will lose all of the properties the family owned because of his brother's financial position.   

The person was in the process of selling the properties to my company when he discovered this information concerning the deed to the family's property having been placed in his brother's name.  The person is still hoping that there is something that can be done, since he and the rest of his siblings don't want to lose the properties, their parents worked so hard to acquire.  Can anyone tell me if there is a solution to this problem that will keep, he and his family from losing their inheritance?
