My sympathy to you and your family. When my mother passed she didn't have a large estate, and in Oregon the court house wasn't much help because anything they might tell you is legal advice, and the lawyers managed to make a law that giving out legal advice illegal. So what my brother and I did was go to a title insurance company to ask about help with the house. The lady at the title insurance welcomed us with open arms and gave us all the information we needed, and said she was glad to do it, because the lawyers always screwed it up. If we had been forced to an attorney there wouldn't have been much left, but with that help we did the rest of the paperwork without any problems. The key to this is my brother and I got along and we were the only heirs. If a family member makes problems is when the lawyers get the most. In Oregon there is an amount of money that if an estate goes over, then the law says there must be probate, and here come the lawyers again. We were right on the boarder line, and were a bit worried about that, but an accountant friend pointed out that there are no probate cops, so we did it ourselves and everything worked out fine, and taxes on the house etc. were handled by the title company. You will need a number of copies of the death certificate, because they have to be used for insurance etc. This was all over ten years ago, so I don't remember any more that that, and every state has different laws, but the feds are only interested if she had enough money to create a death tax, and I think that's over a million now, but you might want to check on that. And in some places life insurance is taxable. I'm not giving legal advice, just what my brother and I did and it worked for us in Oregon.
