As pointed out above, it’s time to get a lawyer even if you can’ afford one because he will be cheaper than losing your home. Does your county not have a Probate Office where wills are filed? I’ve not had to deal with this problem, but I’ve heard others discussing going to the probate office when there was no will on file. I think that they declare you as spouse to automatically inherit all his property. Now other relatives can contest this action in order to get their share, but I do believe that the spouse is considered the primary beneficiary. I read where one woman discovered after her husband’s death that he was a bigamist and she was the 2nd wife. The courts gave everything to the legal (1st) wife and annulled the 2nd marriage.
That just brought up another question in my mind, have you had the car put into your name? DMV may well have their own set of rules in order for you to be able to sell the car later on. I know from when my parents died, it’s easier to take care of earlier rather than later as the necessary paperwork tends to get misplaced and replacing it becomes a nightmare.
