Under Missouri law, if the bank account and property is in your mother's name only, and not in joint names or payable on death or transfer on death to anyone else, then the children split everything equally, subject to outstanding debts that your mother had at the time of her death. If the total is less than $40,000, then in Missouri you can do a small estate affidavit. See an attorney for details. Once the amount is greater than $40,000, you need to do a full probate estate. You and your siblings need to decide who is going to be personal representative. If there is no will, then a bond has to be posted. See an attorney for details.
