How Do Custodial Accounts for Kids Work?

Custodial banking and investment accounts are opened and managed by an adult on behalf of a child. The custodian doesn’t have to be a parent or other relative, but they must commit to handling the money in the child’s best interest. This commitment is also known as a “fiduciary relationship.”

There are two main types of custodial banking accounts: 

• UTMA (Uniform Transfers to Minors Act)
• UGMA (Uniform Gifts to Minors Act)

UGMA accounts allow minors to own cash assets such as cash, stocks, bonds, and mutual funds. UTMA accounts can hold those investments while including other assets such as real estate. 

Make sure you speak with an investment advisor well-versed with custodial accounts to determine which one you should open.

How to Choose a Custodial Account

When choosing a custodial account for your child, you’ll first want to consider your needs. Do you need a checking account for everyday spending? Or maybe you just want a savings account for your kids to start saving money. Or perhaps your kids are interested in investing. Also, consider the features you’ll need in the account.

Once you know what type of account you want, you’ll want to consider convenience. Even though this account is for your child, you’ll still need convenient access to it. You may want to look into accounts where you already bank and invest.

Lastly, you’ll want to look at the fees the account charges. Excess fees will likely frustrate someone just getting into banking and investing, and you want them to have a positive experience. Plus, they likely don’t have much money right now, so every fee can take a big bite out of their balance.

Take your time and choose an account that makes the most sense for your and your family.

Final Thoughts on Custodial Accounts

You can open many types of custodial accounts for kids under 18. You can choose from spending or checking accounts, savings accounts, brokerage accounts, IRA accounts, and education savings accounts.

The custodial account you choose will depend on which benefits you’re searching for your child and the fees, minimum balances, and other features that best fit your needs. 

There’s no need to limit your child to just one custodial account at one institution. Pick and choose custodial accounts based on how they fit the financial goals you have in mind for your child(ren).

And keep fees in mind, as we all know that fees can be vital to how fast (or how slow) your portfolio grows
