Having a sister who lives in Florida, who only had visited once in 5 years and never helps with anything if it involves getting her hands dirty, constantly argues with me to be involved with the finances. Being I live here and have been mothers only caretaker for 11 years, I am the POA . Obviously my sister does not trust me, so I need to make sure I do everything by the book. Being mother is still alive, where do I start.How do I make sure I do things legal? Its never ending and the sad emotional side of things has worn me down and my sisters mean accusations has left me angry.
