How do they work? Would I be able to get money out of it? Or is there some kind of law or rule to where you have to wait til a certain age? Thanks. Oh and I was going to start it with a couple hundred bucks.

My kids both have a custodial Charles Schwab account with a couple of hundred in it.
They way I set mine up.
I set my own brokerage and tied it to my local checking account.
Whenever I need some extra money, Schwab lets me transfer to my checking for free.
Whenever the kids need any extra money - A step needs to be added.
I transfer money out of their account - move it to my brokerage - then move it to my checking. All in one day.

I think the starting amount for a custodial account was $100 - it may be higher now.
Not real simple, but it works.
If you need something simpler, ask your mom to open up a checking account at your local bank for you.
You will get a debit card with your name on it.

Charles Schwab is the best of the best - congratulations.
