Your question does not make sense. You cannot leave someone property in an insurance policy. This is not a will nor intended to be a will. If there was no will made, then the house passes pursuant to your state's laws on intestacy, which usually goes to the surviving spouse first and then to the children equally.
I have handled probate cases for 27 years, and I have not heard of a house being left to anyone through an insurance policy. Many estate attorneys will provide a free consultation, but it is necessary to have some information. If there is not a will, then the property passes in accordance with Indiana's intestacy law, so the answer as to who the house goes to will depend upon who the natural heirs are, if a spouse is involved, if the children are children of the decedent and the spouse, etc.
