Thank you for your Question.
For an answer to your Query, I called the office of Sayyid Sistani and they said :
1- Any money received from the government should go to the person(s) the government intends to send. For instance, if the government intends to send it to the children of the demised, then it is for all of you.(to be equally decided)
2- Regarding the money that your father set aside in the bank, If you had retrieved the money (any legal form) while he was still alive, then that money is yours! But if the money is still in the bank and you hadn’t retrieved it, then the money is an inheritance for all of you 6 children. (Should be divided according to the Shariah)
