Bank errors: Types and how to fix them

鈥淏ank error in your favor鈥 is a good community card to pull in Monopoly, but hearing that your real bank made an error will probably cause your heart rate to spike. But what type of bank errors do you need to be on the look out for, how do you resolve them, and are there times when they are actually in your favor?

shares the most common bank errors and how to fix them.

9 common bank errors

There can be any number of bank errors, which can happen from human error, faulty security systems or just bad actors. Some of the most common banking mistakes include:

  1. Data leaks due to faulty security systems
  2. Human data entry errors
  3. Double-charging fees
  4. Wrongfully charging overdraft or late fees
  5. Lost cash and/or deposits
  6. Illegally not disclosing fees or APR on agreements
  7. Wrongfully repossessing vehicles or homes
  8. Misapplying loan payments
  9. Opening accounts without consumer consent

What can you do about a bank error?

For typical errors, such as a double debit or an incorrect , the process is pretty simple.

For example, let鈥檚 say you deposited a check for $1,000, but only $100 cleared. To get this sorted, there are three basic steps to follow:

  1. Gather proof. Your bank statements will list transactions, and withdrawals, so first you need the deposit date and the transaction number to show the financial institution. If you still have the check (which is recommended until the amount clears), then you have proof that the was incorrect.
  2. Contact your bank. Most banks and credit unions have multiple ways to contact them. Visiting a branch or emailing may be easier when you need to provide proof of a bank error, but you may be able to resolve the issue over the phone.
  3. Get the error fixed. In general, errors like wrongfully deposited amounts or electronic transfer issues are typically corrected within 10 business days. For more complex errors, it may take up to 45 days to resolve.

Do banks owe me money after an error?

Sometimes, yes, you may be owed something if there鈥檚 a major error on the bank鈥檚 part.

In cases of wrongly deposited amounts, the bank should send you the amount you should have received within 10 days (in most cases), but usually no extra compensation. Other smaller issues like double charges should also be resolved quickly, with a simple refund.

However, in more extreme cases, such as errors that impacted thousands of customers like a , an investigation will likely occur. If it鈥檚 found that the financial institution was widely mismanaging accounts or breaking laws that caused the bank errors, a class action lawsuit may follow. If the lawsuit goes through, the financial institution may agree or be required to pay a settlement and/or redress for the mistake.

Here are some examples of lawsuits from bank errors, and how they were resolved.

Wells Fargo: Mismanagement of accounts (2022)

In 2022, the ordered to pay $3.7 billion after mismanagement of auto loans, mortgages and deposit accounts was found to have negatively impacted over 16 million consumers.

The bank was required to pay $2 billion (of the $3.7 billion) in redress to consumers, since customers were being illegally charged fees and interest charges on loans and mortgages, as well as having their cards wrongfully repossessed and mortgage payments misapplied.

LastPass: Data breach (2022)

While not technically a bank, this error trickled down into money errors. LastPass is a , and it experienced a data breach in 2022. A class action lawsuit was filed, since it was found that LastPass failed to prevent an unauthorized person from stealing source code and information, which was then used to steal consumer information.

LastPass agreed to an $8.2 million settlement, and those who submit their claim form with proof of losses tied to the 2022 data breach can claim a one-time payment of up to $300.

Patelco Credit Union: Cybersecurity issues (2024)

Patelco Credit Union is a credit union in California, and in 2024, it experienced a data breach that was allegedly caused by a lack of cybersecurity measures. While the credit union didn鈥檛 admit to any wrongdoing, it agreed to pay a $7.5 million settlement to resolve the class action lawsuit.

Consumers who of losses from the 2024 breach can claim up to $5,000 in reimbursement. Those who did not incur losses from the breach can still claim between $100 and $200, depending on how many class members submit claims.

What if a bank error takes a long time to fix?

In cases where there鈥檚 a deposit error that takes longer than 10 days to fix, there is a regulation meant to help you while the financial institution investigates: provisional credit.

A provisional credit is a temporary deposit in your account from your financial institution that you can use while they investigate a disputed transaction or error. The provisional credit should be the exact amount you are disputing.

Using our previous example of a $1,000 check that only deposited $100, let鈥檚 say you dispute the transaction and it takes your bank longer than 10 days to investigate. The bank should give you a provisional credit of $900 (the missing amount) to tide you over. If the bank error was found to be an actual error, you keep the provisional credit. If the error was found not to be an actual error, the financial institution revokes the provisional credit.

When you open a deposit account, such as a , you鈥檒l have a deposit agreement. These agreements should contain information on how to resolve bank errors, how long it will take the bank to resolve them and information about provisional credits.

What if I made a bank error?

Mistakes can happen to anyone. If you made a bank error, contact your bank to fix it 鈥 just like you鈥檇 contact your bank if they made an error.

Sticking with our checkwriting example, let鈥檚 say you went to deposit a . However, the numerical amount says $1,000, and the written amount says 鈥渙ne hundred dollars 00/100.鈥

According to the Office of the and the , the spelled-out numbers overrule the numerical amounts on a check.

So, in that example, the financial institution would be required to deposit the $100 instead of the $1,000. In cases like this, there isn鈥檛 much you can do besides get another check for the rest of the amount. The financial institution is required to follow the spelled-out words, and the error would fall on you, unfortunately.

Bottom line

Bank errors can happen, and they can happen frequently. Luckily, there are regulators designed to protect consumers and hold accountable for mistakes that harm customers.

The downside is that litigation for major errors, such as data breaches, can take months or even years to resolve. But no matter the error, be sure to contact your bank immediately, save your bank statements showing the error and know your rights.
