Great news and kudos to Mom. That's a symbol of her love and respect for the Diablo clan that she took care of her shit.
That should make things much easier.
PSA - For anyone who doesn't have their financial affairs in order or has parents and you aren't sure if they do - have some conversations with your parents or your kids.
No one likes to talk about death and no parent wants financial advice from a kid who's ass they wiped as a baby - But.....it makes things so much easier after the fact.
Find their hot button and push it.
Maybe they are adamant that they want their death to be treated like a celebration.....Then turn that discussion into saying we want to be able to celebrate your life, not scramble and fight to figure out your estate. Maybe they hate lawyers or the gubment - then tell them you want to make sure their finances are in order so the family doesn't have to pay it all to attorneys and courts to sort it out.
Whatever it takes - get it clear, on paper, and where someone can find it.
And for goodness sakes, everyone needs to go back and check life insurance, retirement plan, IRA, and annuity beneficiary designations periodically - especially if you have had a divorce, death, birth, or change in the family structure. Those things are difficult and sometimes impossible to unwind after death - any the process of even trying is costly to the estate.
@El Diablo I'm sorry for your loss, but am happy for you that this potential burden has been lifted and you can focus on your good memories of mom and not have her death create undue stress and worry.
