My sister and her husband came to my home (I'm 69) where I'm the full-time caregiver for my father (89). She was demanding, since she is on the title with Dad, that he sign over the proceeds from the sale of his property to her to deposit in an account in her name only with him as beneficiary. I protested and the two of them became very verbally abusive and hostile. That was last week and I'm still feeling both the emotional and physical effects of that encounter. Their behavior was in front of my father, but I suspect he's lesser affected due to dementia (but I do have a counseling appointment for him tomorrow just to be sure). I believe they committed elder abuse, harassment, perhaps domestic violence -- would I be able to make a legal complaint?
