I have taken care of mom for 3 years and also work a full time job. My sister who is the Power of Attorney and has no job and financially sound lives in Calif. I live in Idaho. I want her to take mom to her million dollar condo so I can get some sleep in order to keep my job.
Forget your sister, forget trying to nag her awake. Get the Judge to support the move to AL. My guess is she won't even show up at the Show Cause hearing.
You cannot just play hot potato with mom either - you cannot decide sis needs to take her in.
All you can do is draw your own boundaries. You can advise sis that she has 10 days to make arrangements or you will.
Perhaps you can take a week vacation from work and dedicate it to settling mom in an AL. Does mom have the funds, or is the issue that sis was supposed to fund the AL? If mom has the funds -just do it, sacrifice a week and you will get a lot more time back, else you will be stuck.
