My question involves estate proceedings in the state of: CA
"Alice", an 85yr old living in California, w/alzheimers (Stage 5-6, not verified via test) owns 50% of $300,000 home along with "Joan", lifelong friend, (other 50%) of 50 years. "Alice's" 50% stake in home was paid off at time of purchse while "Joan" currently pays her share of the mortgage because she did not want to pay off her half upon purchase due to 401k/IRA penalties. "Alice" has liquid assets of $150,000.00 and roughly $700/month income from 401k/SSI, etc. "Alice" has one child, age 55, living in same county. "Joan's" will leaves all her assets to "Alice's" child as well in the event of "Joans" passing.
Need advice (which specialty, if there is one) on how to avoid draining the $150,000.00 on home care/nursing-home care before letting Medi-Cal take over PLUS not having Medi-call go after the house after "Alice" passes on.
