Did you just have transaction authority over a bank account that was owned only by your father, or were you a part-owner of the account? In other words, was your name on the account?
How much money is in the bank account?
What other assets did your father have besides the bank account?
Who is the executor of your father's estate? If it's you, you should read IRS Publication 559, Survivors, Executors, and Administrators, or seek professional help.
