Do I need to write up a Care Contract to get paid for my services and get paid from mom's estate after she dies? I took over care to prevent selling the farm to pay a nursing home. Can I be kicked out of mom's house by my sister (executrix) when my mom dies?

In your situation I think you need to talk to an Elder lawyer as suggested. Five years is a longtime to care for someone who has ALZ. The farm could be sold and she could be placed in a nice Memory care Facility.
