My father passed away in Dec 2009. I was appointed Trustee of his affairs. My name is on both checking and savings acct. A person who owed him money just sent me a check that is made out to the estate of (name). The bank will not accept the check unless I open an Estate account. The bank states that I just have to go to the courthouse and get some type of letter which allows me to open the estate acct. and a tax ID number. Can I do this myself?
