My mother died without will I am the voluntary administrator she has 130 thousand in the bank her bank told me I need to open an estate account and then when I have tax id number they will transfer monies then I can distribute to my siblings I want to open account online I do not want to use a lawyer I live in brroklyn ny she lived in queens do you know which site I can go to do this?

Why do you want to use a online account ? You will still have to get a tax ID number, that is merely picking up the phone and calling the IRS.
Then why not just use the bank where the money is at.
And of course all of her bills will have to be paid out of the account before money is paid out.
