A Teen’s Guide to Helping Parents Invest Safely and Legally is designed for young people who want to support their parents in making smarter financial decisions. As many parents approach retirement or face challenges with online investing, teens and young adults are increasingly stepping in to help. Whether it’s explaining how brokerage accounts work, comparing investment platforms, or ensuring that every step follows the law, understanding how to assist safely and legally is essential for both generations.
Helping parents invest safely and legally isn’t just about managing money—it’s about understanding the boundaries of financial responsibility. Teens and young adults who wish to guide their parents must recognize that certain actions, such as opening or handling investment accounts, require proper authorization. By learning how brokerage regulations, power of attorney, and joint account rules work, you can provide meaningful support without crossing legal lines. This guide explains everything you need to know to help your parents invest confidently and within the law.
The good news? Most major online brokers offer a straightforward process to legally establish the right permissions—whether through a power of attorney (POA), joint account, or limited trading authorization.
Key Points
-
Minors (under 18) cannot open or manage investment accounts for themselves or for others.
-
Upon reaching the age of majority (usually 18), individuals gain the legal capacity to open accounts but still need authorization to manage someone else’s investments.
-
A power of attorney (POA) provides the broadest authority to handle another person’s investments.
-
Online brokers such as Fidelity, Schwab, or Vanguard offer forms and step-by-step instructions for setting up these arrangements legally.
Can Teens Open Investment Accounts for Their Parents?
No. Teenagers cannot legally open an investment account for their parents. Financial institutions require the account owner’s consent, and account applications must be signed by a legal adult—typically age 18 or older.
That said, teens who want to support their parents financially can still play a helpful role:
-
Researching investment options or comparing online platforms
-
Explaining basic investing concepts, such as diversification or compounding
-
Walking parents through dashboards and mobile apps
-
Helping them understand the differences between brokers, robo-advisors, and retirement accounts
Even though teens can’t legally open or manage an account, being a guide and support system can make a meaningful difference.
Legal Age and Financial Authority
In most U.S. states, the age of majority is 18—the minimum age to sign contracts or open financial accounts. Before that, minors cannot enter into legally binding financial agreements or represent another person in a financial matter.
Once you turn 18, you can open a joint brokerage account with a parent. However, this arrangement comes with shared ownership, access rights, and tax responsibilities, which should be considered carefully.
Other options include:
-
Trusted contact designation: Allows a brokerage to reach out to you if there are concerns about your parent’s account activity, though it doesn’t grant control.
-
Power of attorney (POA): Grants you legal authority to make financial decisions for your parent.
-
Limited trading authorization: Lets you place trades on behalf of your parent but does not allow fund withdrawals.
How Teens Can Help Without Legal Authority
Even without the ability to manage an account, teenagers can still provide valuable support in several ways:
-
Start the conversation. Ask your parents about their investment goals and comfort with financial tools.
-
Do the research. Compare online brokers, investment options, or automated portfolios.
-
Offer tech help. Many older adults struggle with digital platforms—simply guiding them through an online brokerage dashboard can be a huge help.
-
Recommend automation. Robo-advisors such as Betterment or Wealthfront automatically adjust and rebalance portfolios, making investing simpler for those who prefer a hands-off approach.
For parents who prefer more control, full-service online brokers like Charles Schwab, Fidelity, or Vanguard are great choices. You don’t need legal authority to provide explanations or help them understand what each feature means.
What Changes Once You Turn 18
At 18, you gain the legal capacity to open your own investment account. However, managing someone else’s account still requires formal authorization. The most common legal arrangements include:
-
Power of Attorney (POA): Allows full management rights, including buying, selling, or transferring funds.
-
Joint Brokerage Account: Provides shared control but also shared liability and tax obligations.
-
Limited Trading Authorization: Grants trading rights without allowing withdrawals or account closure.
-
Authorized User Status: Offers limited access to monitor or assist without ownership rights.
Each option has its own implications for control, taxes, and liability, so it’s best to discuss them with a financial advisor or attorney before proceeding.
The Bottom Line
Helping your parents with investing is admirable—but it must be done within legal boundaries. Teens under 18 cannot open or control investment accounts for anyone, including themselves. Once you reach adulthood, you can play a more direct role, but formal authorizations such as POA or joint accounts are still required to act on someone else’s behalf.
In the meantime, focus on being a knowledgeable helper: research, educate, and guide your parents through digital investment tools. When handled with transparency and respect, your support can empower them to make smarter, more confident financial decisions.
