I am sorry to hear about your loss. To address your question, I would advise you to speak with an attorney who specializes in Probate. The situation you are speaking of is called "Dying Intestate" which means they died without a will, and the law has some very specific rules regarding how the assets (homes, cars, money, etc.) owned by someone who dies without leaving a will are to be divided amongst their family members.
Contact the lawyer as soon as you can because it will take some time to get these things sorted out and the County has a process headed by a person called a Public Administrator whose job it is to protect the assets for the lawful heirs (siblings, children, grandchildren, etc.) or, if the person had no family, the State.
If you need any further information, assistance or have any other questions, Please do not hesitate to contact me and I will be happy to help you to the best of my ability.
Take care and have a wonderful day!
