My grandmother died she had a living trust that made my mother the trustee and beneficiary of almost all the assets except for 1 dollar that goes to my uncle. My uncle has not been in my grandmothers life for 20 years. She gave him a dollar out of spite. He already said he is going to contest the trust. Can he do this? And what are the chances he would be successful? My grandmother was of very strong mind and body when she wrote this trust.
