My grandmother passed away March this year and left her home and estate to myself, my brother and my cousin. My uncle (her Son) is contesting her wishes wanting half of the estate and her house. In the past he had to declare bankruptcy, he was abusive to his wife and daughter, he was a gambler, lost his and his brothers inheritance and had been incarcerated for drug trafficking. The public trustee is the executor of the Will. We have said no to his demands. Is there anything more we can do to protect our grandmothers Will and her wishes for us?
