There are 2 grounds that are normally used when contesting a will. One is lack of competence. The other is undue influence, whereby a person close to him used their influence (usually in a diminished state) to essentially substitute their judgment for his. These issues often come up when someone changes their will close to death. You may want to investigate when the will was done, who drafted it, who was with him at the time and what drugs he was taking. Remember that as a niece, contesting the will and invalidating it doesn't mean that the estate will go to you!
