My mother-in-law (MIL) has an account Joint Tenants by the Entirety with her daughter. MIL opened the account and funded the account with her money. She added daughter to the account some years later. Daughter claims the money is hers. MIL is in pretty desperate need of this money; it's approximately $21,000. She called the financial institution which sent her a check (made out to both of them), but her daughter somehow stopped payment on it and also wrote a letter to the financial institution not to release any money without her approval. Daughter has no relationship with my MIL, my husband, or myself. I have called, emailed, and texted her. I even told her she was committing financial elder abuse. I received no response. MIL is 79, has dementia, is bedridden and can't care for herself. Her boyfriends lives with her but he isn't capable of providing adequate care for her. She needs either care in her home or to go to a nursing home. If she goes to a nursing home, Medicaid won't initially pay because of the $21,000 account. This is in Florida. I have called Adult Protective Services, but have not gotten anywhere thus far. Any advice would be greatly appreciated.
