Dad has been coerced by his wife (90's) to only let the step sister take care of health and business. Dad tries to talk about important topics but backs down when his wife pounds on the table and yells, "( Her) Daughter will do it. We will make our own decisions." The secret now known is they have been paying this daughter to help. This payment makes him feel independent.
They need trusts to replace their simple will. I was not invited to the first meeting. We all went to the second. The lawyer only presented the 1 unethical choice ( with intentional confusion)that would put most of their money under her control with the promise of dispersing it properly, give her POA over both. POA was not mentioned to parents but I know it's and integral part of any plan at this age. Step chose only the plan she and lawyer wanted presented. I have sound legal and financial advice about blended families but am open to hear more information. Dad did not want to return to the unethical lawyer. Great. I offered to make an appt. with a referred lawyer for all of us. All seemed to be in agreement. Time confirmed. Now stepmother is suggesting they will not attend. I can never speak alone with my dad. Step sister clearly does not want me to be alone with them. Now I think Dad is being convinced he should let her control the bill paying. I am panicked about what will happen in the next 3 weeks before we meet with the new lawyer. What will dad sign in the meantime without me. How do I protect my dad and get him to hear uninterrupted advice if he lets others prevent it? Will a signature under duress be legal? Dad can understand the information if professionally presented. Step mom can not connect to the second step.
If I were Dad, I would go to a lawyer of my choice and protect his half of the assets for you and him. He can also assign you as his POA for financial and medical revoking stepdaughter. This has been done. He can make up his own will making u Executor. For now, he is competent so if Step has a POA it is not in effect. He is capable of making his own decisions. I would ask him to not sign anything until he sees a lawyer.
