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: 

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.

Final Thoughts on Custodial Accounts

There are many types of custodial accounts you can open 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.
