Just to clarify, when stated that you could benefit as an heir, this is only if no valid Will is in existence and this also assumes that the estate has more in assets than in debt.
I was her care giver and she has no other family I know she went to the funeral home and wrote down what she wanted me to have and he then he told her to give him a few days so he could get it typed up but she passed away before she could get back up there. I went and spoke with him and he remembers her telling him that she wanted to leave everything to me.
Let me be frank. If you were a paid caregiver, you should not receive her assets, except in rare situations, as you were in a position to influence her. You were hopefully paid for your services and friendship but this should not put you in a position to gain any of her estate by providing these services. When I hear about one of my clients who is being cared for by a paid caregiver giving any gifts to the caregiver, I immediately think of foul play and I have taken actions to make sure it is stopped. Sorry if this comes across harsh and I am not judging you personally but this is a situation ripe for abuse.
