In October of 2005, my sister called me to inquire whether I had paid $1,000 back to my father that I had borrowed earlier in the year. I told her I had not and that I had sold my house and was now able to do it. I was living in a group home at the time and my sister suggested that since she worked at a bank, she could save me the wire fee and that I should just send her a cashier's check for $1,000 and she would just be able to deposit it into Dad's account because she worked at the same bank that he banked at. I sent her the cashier's check and trusted that she had deposited it into Dad's account. I was living in Florida at the time and my father and sister lived in Iowa. I recently found out that she did not deposit the cashier's check into Dad's account after all. I was unemployed at the time and was living off the proceeds of my home. I was also disabled and awaiting pay from Social Security Disability. My sister would send cheap little gifts and a $20 bill here and there and then in 2008, I received my back pay from SSDI and 1 month prior to doing so, I let my sister know that I would be receiving back pay and what the amount was. I was unaware at the time that she had kept the $1,000 in 2005 that was intended for my father and I wanted to show my appreciation for her gifts and all her caring, so I sent her a $1,500 cashier's check. Now in 2011, she denies ever having received any money from me for anything. She is saying that I am sick and that I am basically delusional. I have documented proof that she has received two separate cashier's checks from me. What can I do? All the gifts and cash she had been sending me from approximately March of 2006 until September of 2008 were either my money or paid for by the $1,ooo cashier's check that she kept instead of depositing it into Dad's account. Please can someone help me with this matter?
