^TomTX, You should definitely be buried with your bicycle bell!
It's definitely had an impact on how I want my estate plans to look. My kid's guardianship will be separated from the money. My parents would be the current choice for guardianship, but a trustee would release funds at regular intervals. I'm not saying that my parents would have him living under the stairs like Harry Potter, but I bet he'd end up taking a whole lot of cruises on his dime.
I share this issue, and so I gave the purse strings to my stingiest relative. She's not great at investing, but she's not a spender, so my hope was that she would just follow my lead on where to keep it parked in index funds. I thought about having my local credit union act as trustee. They charge 1% per year to manage the estate, releasing funds only for the health, education, welfare, and maintenance of the child.
Otherwise, yeah, in the hands of other relatives there would be "family" cruises. And home remodels. And new bigger cars. I don't begrudge someone who is taking care of my kids having money to be comfortable, but odds that it would be wiped out before the kids reached adulthood are high.
I've seen plenty of advice to delay giving inheritance to young adult children. Sometimes the advice is given with caveats like "they will meet some gold digger who will then divorce them and take half the money." I even had my will set up that way for awhile, a delay for full disbursement until they were 30 years old. However, I've also seen plenty of examples of people in their 40's, 50's, and 60's who are spendthrifts and will blow through huge amounts in no time. There are even TV shows about it like
Money Moron and
Til Debt Do Us Part.
So, now that my kids are young adults, they will just get it directly. I updated my will when they turned 18 to just give it straight to them because the named trustee is starting to have memory problems. I don't have any other viable trustee options in my family. So it's straight to the young adult kids or a trustee like a lawyer or bank who will take a cut.
This weekend I'm going to work on updating my estate planning and I will write both children letters to put in my estate planning portfolio. That way my "wishes" for what they do with the money will be clear: hookers and blow.
Just kidding. I probably will write something like "take 5-10% of the money and get yourself a limited amount of some discrete fun things you really want right now, like maybe a vacation or vehicle or furniture or some clothes, etc. Remember me while you are living well enjoying that! Then the party is temporarily over. Please keep the rest parked in passive Vanguard stock index funds using the advice from here, here and here. Don't touch the principal! Let's this money grow from this little pile to a giant pile in 10-20 years by riding out dips in the market without meddling. That's what Warren Buffet wants for his children, and that's what I want for you."
But, after all, I'll be dead, so I'll just have to trust that they absorbed some common sense about how to manage money from our conversations and from watching how my financial situation improved over time. They already have Vanguard Roth IRA's, after all.
