My mother past away about 2 weeks ago. It was only me and my sister, the catch is that my mother has a large home with allot of expensive merchandise. Me & my sister are not sure if my mother left a Last Will & Trust. Me & my sister are both on the death certificate but my sisters boyfriend works for the mortuary were my mother was cremated. I'm not sure if my sister will try to get over on me while I'm at work, were as she can go to the bank and try to seize my mothers bank info, deed & trust to the home etc. without me? Can she do that with me not being there & take everything? She also had a live in boyfriend for 11 years, what are the legal rights that he has to the house until me & my sister locate the Last Will?
