If there was no will then the property will be held in probate until a disbursement is made. You will need to contact the probate attorney right away to discuss options on how to keep the home. Often a family member who will inherit the house will move in and pay "rent" to probate where the rent is used to keep the mortgage payments up to date.
Add on to my question up there lol....... Going in to up and he does not want to lose his mothers home is there anything we can do about it even know the deed or will wasn't in his name???? please help we want to keep the place and get it back on track with payments.
