We believe that our step brother is abusing our mother's financial left by his dad when he died. His dad made sure he had all the power. They threw mom in a nursing home, and continue to live in her house until she dies. They have moved the entire family in, and use moms money to pay all the bills. He will not provide any proof of how he spends her money. They take elaborate trips, and have the best of everything. When we ask for a financial accounting of her money, he refuses and says we are contesting her will and will make sure we get nothing and he gets everything. We think this is elder financial abuse. Is this contesting a will while she is still alive? We believe that this is elder financial abuse fueled by their greed. This is in Washington State.
