My mom's estate seems to be winding down, with the last thing in an IRS refund. Even though we filed that we were done, it takes another year past the date we file until it will be formally closed--that was unexpected and annoying, as I thought it would be closed when everything was completed, but no.
If anyone is in charge of their parent's finances or helping, or if anyone is an executor, make sure you check the unclaimed funds for every state where they've been living. We waited about six months for one state to pay out the bank account that had gone to unclaimed funds. It took four years to get Wells Fargo to pay an account in my dad's name, and those two things probably put us back a year with mom's. We are at two years now.
I still have nightmares about their house, where I am trying to reclaim things from the house, but maybe those will go away soon. I have a lot of sadness about the past few years, but I did a good job for mom and dad, so that's a comfort.
I think if I were asked to do this again, I would not do it unless it was for my husband or one of the kids. I would not do it if there was conflict between any of the parties.
On the other hand, doing it oneself is better than blindly trusting the lawyers, as ours were not great. So it was better to not be passively waiting for them to make mistakes.
I found my dad's ledger books from both of my grandparents when he was their executor. I've got mine and I boxed them up in the attic. I'll keep the boxes for a while, and go through them again in a year or so when it is finally closed. I have been getting rid of things as we progressed--down from about five boxes to one and a half.
