I suspect someone is abusing my mother's finances. There is a high probability of this going on now and has been for a while.

The person has been given free access to my parents (mother/Step-father) finances by my step-father. When we try to tell him what is happening, he is in denial. I want to get the finances out of their hands and into mine or my siblings. Their bills are not getting paid and their money is disappearing. I would like to contact a lawyer. I live out of state. Can I get someone to email me, or call? I would like advice on what I can do. Thank you.
