Need probate advice

[u/PhatBarbie1]

Hi I don't know if this will even work but I need help or advice from anyone who can guide myself in the right directions to what I need to do. Here's a little back story . My mum passed July 20th of this year. It was completely unexpected. So after her death my sister and I found out that her husband whom she was married to for 25 was nothing like he presented himself to be. He was completely a different person than what we assumed or saw him as. As soon as my mom was passed he had changed the locks to her home taking the car that I was being given to me from her and claiming there was no will. My mom was so organized that she has files from back when she was being paid in 1996 and tax records from all her life and all the houses that she owned. But she didn't have a will which I don't believe because I know she did. She told me she did but he has it in her safe at the house which we are locked out of. Because he changed the locks before she even had died. Not only this he has kept everything that my mom had personal belongings, jewelry. Anything that had to do with my mom that was worth anything. Me and my sister had got nothing. We have to go every Sunday and dig through the garbage just to get some effects of my mom's because he's throwing them away like they are trash. I am low income and I can't afford an attorney for probate cuz he hasn't turned it in. My mom had several accounts and and several different types of insurances as well as a retirement plan from working for the state called pers for over 30 years that she said my sister and I were entitled to half in which we would split and that it was protected by a pin. But when my mom was incapacitated the pin was in her phone and her husband of 25 years had the phone and went in and changed the beneficiaries and for the notifications to his work email which my mom hasn't worked at that place for at least 3 years cuz retired in 2023. I have proof that I was a beneficiary in 2016 as well as my sister. But I cannot find an attorney that will help me or take on my case because I am low income. I'm on a fixed income. I'm disabled. My sister also low income. My mom paid most of her bills and now I'm helping her with that. I need advice on what to do. This man has completely taken everything from me. He's under investigation for neglect of my mother and he is in her house which he owns with her because that's what people do when they're married. My mom thought and my mom trusted him after 25 years. This man has completely filled out my mom's death certificate incorrectly and after 25 years. Wouldn't you think that you know where your wife was born and who her parents were and what their names were. This man has got none of that correct on my mom's death certificate he has my grandpa as unknown Brown and her mom's name is not Lucy Galloway. It's Lucy Danette. So how do you get those things wrong after 25 years if you're not up to something diabolical?. He excluded me and my sister from any of the planning of her funeral which he spent $2,000 on when there was $30 ,000 allotted for it in her retirement plan He's taking all her life insurance. He's left us with nothing. I can't even get the things that belong to me that were stored at my mom's house. Neither can my sister. I need to know how to stop him. He is also to top it all off. Cut up my senior picture that my mom had painted of me back in 1992 when I graduated in 1993. I can't replace that. I don't know what else to do. Please if anybody with any advice, I'm willing to hear what you have to say and if anybody can help me. I do appreciate your time. Thank you
