How to Monitor Bank and Financial Accounts for Someone You Care For

What monitoring tools actually do

Financial monitoring tools let you see account activity, balances, and transactions for someone else's accounts — but they work differently depending on whether you have legal authority and what the financial institution offers. Some tools show you everything in real time; others send you alerts only when specific things happen. The tool you can use depends on your relationship to the person, what documents you have, and which bank or service you're dealing with.

Most banks offer at least one way to monitor an account if you have the right paperwork. Some let you set up alerts on a shared account. Others require you to be named as a fiduciary — someone with legal power to act on the person's behalf — before you can see anything. A few let you view accounts without being on the account itself, if you have power of attorney or guardianship papers.

Key Takeaways

• Banks offer different monitoring options depending on whether you're a co-owner, authorized user, power of attorney, or guardian — ask your specific bank what each role can see.
• Real-time alerts for large transactions, unusual activity, or low balances are available at most major banks and can catch fraud or overspending quickly.
• You will need to bring legal documents (power of attorney, guardianship order, or conservatorship papers) to the bank in person or by certified mail to set up monitoring if you are not on the account.
• Online banking portals and mobile apps let you monitor accounts from home, but you still need the bank to grant you access first — having the password is not enough.
• Third-party aggregator apps can pull information from multiple banks into one place, but they require you to give them login credentials and may not show the most current balance.

Monitoring when you are a co-owner or authorized user

If you are already on the account as a co-owner or authorized user, you can usually set up monitoring through the bank's online portal or mobile app right away. Log in with your own credentials and look for settings related to alerts, notifications, or account sharing. Most banks let you choose what triggers an alert: a transaction over a certain dollar amount, a balance below a threshold, a withdrawal from an ATM, or a purchase in a specific category.

Co-owners have the same access as the account holder and can see all transactions and balances. Authorized users (sometimes called signers) may have more limited visibility depending on the bank — some show everything, others show only transactions you made yourself. Call the bank and ask what an authorized user can see before you set anything up, so you know whether you need a different arrangement.

If you need to monitor the account but are not yet on it, you will need to go to the bank with the account holder (if they are able) or bring legal documents showing you have the right to manage their finances. This is covered in the next section.

Adding yourself to an account using power of attorney or guardianship

If you have a power of attorney document signed by the person whose account you need to monitor, you can usually add yourself to the account or set up monitoring without the account holder being present. Bring the original power of attorney (or a certified copy) to the bank in person, along with your ID. Some banks will also accept it by certified mail if you include a notarized cover letter.

The bank will verify that the power of attorney is valid in your state and that it covers financial decisions. Some powers of attorney are limited to specific accounts or transactions, so the bank may ask you to clarify what you are authorized to do. If the document is unclear or outdated, the bank may refuse it — in that case, you will need a new one drawn up by an attorney.

If you have a guardianship or conservatorship order from a court, bring that document instead. The process is similar: the bank verifies the order, and then you can add yourself or set up monitoring. Guardianship and conservatorship orders are usually stronger than power of attorney because they come from a court, so banks are more likely to accept them without question.

Once the bank accepts your documents, ask them to explain what access you will have. Can you see all transactions? Can you move money? Can you add or remove authorized users? Can you change the mailing address? Get the answers in writing if possible, so you have a record of what you are allowed to do.

Setting up alerts and notifications

Alerts are one of the fastest ways to catch problems. Most banks let you set up notifications by email, text, or both. Common alert types include: transaction over a set amount (like $500), balance below a set amount (like $1,000), ATM withdrawal, online transfer, check deposit, or unusual activity the bank's system flags.

Set alerts based on what you are actually worried about. If the person tends to overspend, set an alert for transactions over a certain amount. If you are concerned about fraud or someone else accessing the account, set an alert for any ATM withdrawal or online transfer. If the person lives on a fixed income and you want to make sure the account does not run dry, set an alert for a low balance.

Check the bank's alert settings every few months to make sure they are still working. Banks sometimes change their systems, and alerts can get turned off accidentally. Also ask the bank whether alerts go to you, the account holder, or both — you may need to adjust this depending on whether the account holder can understand the alerts themselves.

Using online banking and mobile apps

Once you have access set up at the bank, you can monitor the account through their website or app. Log in with your own username and password (not the account holder's). Most banks show you the current balance, recent transactions, pending transactions, and scheduled transfers or bill payments.

Online banking is usually faster and more detailed than calling the bank or visiting in person. You can see transactions from the past 30 to 90 days without asking, and many banks let you download statements or export transaction lists. Some apps let you take a photo of a check to deposit it, freeze or unfreeze the debit card, or report a transaction as fraudulent — all without calling.

The main limitation is that online banking shows you what the bank has processed, which may not be the most current information. A transaction can take a day or two to show up. If you need to know the exact balance right now, call the bank or visit an ATM. Also, if the account holder or someone else changes the password, you may lose access — ask the bank whether you can set up a separate login that is not tied to the account holder's password.

Third-party apps that combine multiple accounts

Apps like Mint (now part of Intuit), YNAB, or your bank's own aggregation tool can pull information from multiple banks and investment accounts into one dashboard. This is useful if the person you are monitoring has accounts at several different institutions. Instead of logging into five different banks, you log into one app and see everything.

These apps work by asking you to give them the account holder's login credentials — username and password — so they can pull the data. This is a security risk if the app is hacked or if you lose your phone. Most banks now discourage this method and prefer that you use their own online portal instead. If you do use a third-party app, change the account holder's password after you set it up, so the app has the old password and the account holder has a new one that you do not know.

Another limitation is that third-party apps may not show the most current balance or transactions. They pull data on a schedule (usually once a day), so you might see information that is several hours old. For real-time monitoring, use the bank's own app or website instead.

What to do if you spot a problem

If you see a transaction that looks wrong — a charge you do not recognize, a withdrawal the person did not make, or a pattern that concerns you — contact the bank immediately. Do not wait to see if it resolves itself. Call the number on the back of the debit card or on the bank statement, not a number you find online, to make sure you are talking to the real bank.

Report the transaction and ask the bank to freeze the account or card if you think someone else is using it. Most banks can do this over the phone and will send you a new card in the mail. If the person has been a victim of fraud, the bank may reverse the fraudulent charges, but this can take weeks. In the meantime, make sure the person has access to money they need for daily expenses.

If you suspect financial abuse — someone pressuring the person to give them money, or making large unauthorized transfers — contact Adult Protective Services in your county or state. They can investigate and may be able to get a court order to protect the person's accounts. You can also report suspected fraud to the Federal Trade Commission at reportfraud.ftc.gov.

Frequently Asked Questions

Can I monitor someone's account if I do not have power of attorney?

Only if you are already on the account as a co-owner or authorized user. If you are not on the account and do not have legal documents, the bank cannot show you the information — it is protected by privacy law. You will need power of attorney, guardianship, or conservatorship papers to add yourself or set up monitoring.

What if the person I am monitoring does not want me to see their accounts?

If they have the mental capacity to make their own decisions, they can refuse to let you monitor their accounts or can remove you from the account. If you have guardianship or conservatorship, you have the legal right to monitor regardless of their wishes, but you are required to act in their best interest. If you are concerned about their safety or finances, talk to an elder law attorney about what your options are.

Do banks charge a fee to set up monitoring or alerts?

Most banks do not charge for basic alerts or online access. Some banks charge a monthly fee for accounts with certain features, but monitoring itself is usually free. Call your bank and ask before you set anything up.

What if the account holder changes the password and locks me out?

If you have power of attorney or guardianship, you can go to the bank in person with your legal documents and ask them to reset the password or give you a separate login. If you do not have legal documents, the bank cannot help you — you will need to get power of attorney or guardianship first.

Can I monitor someone's credit card or investment account the same way?

Credit cards and investment accounts work similarly to bank accounts — you need to be on the account, have power of attorney, or have guardianship to monitor them. The process is the same: bring your legal documents to the financial institution and ask what monitoring options they offer. Some investment firms have different rules than banks, so call ahead and ask what you need to bring.
