I had POA for my mother and was getting ready to file a complaint with the DA's office and wanted to sue him in court. He had wiped her out of any thing of value. I have nothing to fall back on now to cover any sort of burial or cremation. I have 2 brothers: this one that abused mom and another who is estranged. Actually both are estranged. They wouldn't have anything more to do with her while alive. And she said she (verbally) wanted me to have the house. I told her mom you can't give me the house. You have a reverse mortgage. I have been taking care of her for some time without any compensation I haven't had any income in years lived off what I saved. Then dementia set in. The hospital killed her. I am stuck here not knowing what to do. From what I understand these documents I have end at her death. Because He got me for $4K from my saving her house that went into default and paying her utilities and food because he was taking her SS benefits from her account (account take over) depositing them illegally into his represented account. Which was commingling too! He was NOT allowed to have access to his OR her money! I know she had a will 20 yrs ago. But my financially abusing brother may have gotten hold of that document along with all her documents and I know he destroyed everything that he had in his grubby mitts. He's mentally ill.
I think if you get an attorney then that attorney can at least help to reassure you that this was legally done and is over with.
As far as caregiving and receiving nothing to do so, it is far too late for that to be remedied. That has to be done at the time.
I am sorry for your distress. Get an attorney, take your evidence, and get some reassurance so that you can move on.
At some point you claim in your question to us that the Hospital "killed" your mother. Such claims do cause us to sit up and wonder. I hope you will eventually find peace to move on with your life. I am sorry for your loss, and for all your distress.
