My Dad (has LBD) moved in and built an in law apt which he paid for. Since then, he has paid my sister to take him on errands vs hire a caregiver as he’s paying her half the going rate. My sister shows 50% of the time depending on her need for cash. She is extremely toxic, bordering on being emotionally and psychologically abusive to whoever is in her crosshairs. It’s been this way since she was in her early 20s - she’s now 47. My parents have given her everything she’s ever wanted and has never held down a real job. My issue is that she is deliberately nasty and conniving and do not want her near me which is why I moved an hour plus away from my family years ago - just far enough that an effort would have to be made on their part (which they rarely did). My question is: do I have the right to forbid her on my property if Dad paid for his in law apt? To be clear, I know some families have issues with one another; this is different. My sister fraudulently transferred my moms house into a trust naming her sole beneficiary and her best friend trustee. She moved into my moms house after mom had a stroke and within a couple of years had mom hooked on so many pain killers, mom had to detox twice. The last time she was clean, mom almost od’d on a second fentanyl patch that sis “accidentally” put on Mom right after her discharge from detox. Shortly thereafter, mom had a 2nd small stroke and refused meds during the day - only wanted something to help pain at night. My sister started the morphine kit - it took her 8 days to die. Horrible to watch; no legal rights to stop it. Not mentioning this for sympathy but to understand my sister is really not a good person but do I have the right to forbid her on my property if Dad paid for the apt??
