In Florida, if you leave over $25,000 to a minor, you have to set up a guardianship for that minor. There has to be a legal court appointed guardian to manage their property, and that is expensive, because not only are you paying for a guardian, you're also paying for a guardian's attorney bills as well. The guardianship ends at 18, which means that whatever's left at 18, the child can get lump sum. Sometimes it's a really large amount of money all at 18, and that could be really bad idea.

                    

Much better to set up some kind of trust in your will and that is a sub-trust underneath your last will and testament it's built into it, and name a trustee to manage the child's money while they're growing up to put them through college once they turn 18 or go to some vocational training to get started in some kind of profession or an occupation, and then give them lump sums when they're old enough and they're mature enough to get lump sums. For example, like half at 25, the rest at 30, the rest at 35, or you can do as many bites at the apple as you wish. But that way, your child has a chance to mature into the money, you don't have to pay for an expensive guardianship, and you've left someone in charge of their money that you trust.
