Since I don't have a lot or even middle class worthy and don't have kids, it's just me, I don't think about it. I assume my parents will be gone before me. I do have a brother 9 years younger than me so I should do something.

Is it sufficient enough to write down on a paper and have it notarized where you wish your bank $ and 401K should go? My car is paid off and there's just stuff in my apt which I'm sure is not monitored by anyone and can be a free for all in the family.

Write it up, have it notarized, and give it to someone for safekeeping good enough? TIA
