The legal ways to debit someone's account
You can only take money from someone else's checking account if they have given you explicit permission to do so. The most common legal methods are: they write you a check, they transfer money to you through their bank, they set up automatic payments to you, or they add you as an authorized user on the account so you can withdraw directly. Without one of these forms of consent, taking money from someone's account is theft, regardless of your relationship to them or your reason for needing the money.
If someone owes you money and refuses to pay, you have legal options—but direct access to their account is not one of them. Those options include small claims court, a demand letter from a lawyer, or a wage garnishment order (which requires a court judgment first). This section covers the legitimate ways money moves between accounts when both parties agree.
Key Takeaways
- A check, bank transfer, or automatic payment requires the account holder to initiate the transaction themselves—you cannot force it.
- Adding yourself as an authorized user on someone else's account requires their signature on the bank's form and their presence at the bank or online portal.
- ACH debits (automatic recurring payments) need written authorization from the account holder, which the bank keeps on file.
- If someone owes you money and will not pay, small claims court or a wage garnishment order are the legal paths; direct account access is not.
Checks and direct transfers the account holder initiates
The simplest way to get money from someone's checking account is to ask them to send it to you. They can write you a check, which you deposit into your own account. They can also log into their bank's website or app and transfer money to your account directly if they have your routing number and account number. Both methods put the account holder in control—they decide the amount and when it happens.
These methods are safe for both of you because the account holder's bank records show they authorized the transaction. If a dispute arises later, the bank's records prove consent. No third party (like you) has access to the account, so there is no risk of unauthorized withdrawals.
Becoming an authorized user on their account
If you need regular access to someone's account—for example, to help a parent pay bills or to manage finances for a family member—you can ask them to add you as an authorized user. This requires them to contact their bank, fill out a form, and usually sign it in person or through a verified online process. The bank will issue you a debit card linked to their account, and you can withdraw money or make purchases using that card.
Being an authorized user is different from being a joint account holder. As an authorized user, you can spend the money but you do not own the account. The account holder can remove you at any time without your consent, and they remain liable for overdrafts or fraud. If you want equal ownership and control, you would need to become a joint account holder instead, which requires a different process and gives you both full legal rights to the account.
ACH debits and recurring automatic payments
An ACH debit (Automated Clearing House debit) is a recurring automatic withdrawal from someone's checking account. Utility companies, subscription services, and loan servicers use ACH debits to pull payments on a set schedule. To set up an ACH debit from someone else's account, you need their written authorization—usually a form they sign that gives you permission to debit their account on specific dates for a specific amount.
The account holder's bank keeps this authorization on file. If they dispute the charge later, the bank will ask to see the signed form. Without it, the bank will reverse the charge and may close your merchant account if you attempt unauthorized debits. If you are a business collecting recurring payments, you must follow the National Automated Clearing House Association (NACHA) rules, which require clear disclosure of the amount, frequency, and the account holder's explicit consent before the first debit.
What happens if someone refuses to pay you back
If someone owes you money and will not repay it, you cannot legally access their account to take the money yourself. Doing so is theft, even if they genuinely owe you. Your legal options depend on the amount and your location. For debts under a few thousand dollars, small claims court is usually the fastest and cheapest route. You file a claim, present evidence of the debt, and if you win, the court issues a judgment in your favor.
A court judgment does not automatically give you access to their account, but it does allow you to pursue collection methods. You can request a wage garnishment, which orders their employer to send a portion of their paycheck to you until the debt is paid. You can also file a lien against their property or request a bank levy, though a bank levy requires additional court orders and varies by state. A lawyer can advise you on which method makes sense for your situation.
Fraud and what to do if someone debits your account without permission
If someone has taken money from your checking account without your consent, report it to your bank when ready. Call the number on the back of your debit card or log into your online banking portal and look for a "report fraud" or "dispute transaction" option. The bank will freeze the transaction and begin an investigation. Under federal law, your liability for unauthorized debit card charges is limited to $50 if you report it within two business days, and $500 if you report it within 60 days. After 60 days, you may have no protection.
If the unauthorized debit came through an ACH payment (not a debit card), you have different protections. You can dispute the charge with your bank, and the bank must investigate within 10 business days. If the debit was truly unauthorized, the bank will reverse it. If someone set up an ACH debit using your account information without your permission, that is a federal crime. You can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov, and you can also report it to local police.
Frequently Asked Questions
Can I use someone's routing and account number to take money from their account?
No. Knowing their routing and account number does not give you the right to debit their account. You can only use that information if they have explicitly authorized you to do so—for example, if they asked you to set up an ACH payment on their behalf. Using it without permission is fraud.
What if I have power of attorney over someone's finances?
Power of attorney gives you the legal right to act on their behalf, including accessing their bank account. However, you must still follow the law: you can only spend their money for purposes they authorized or for their benefit. You cannot take money for yourself. If you misuse power of attorney, you can be sued and face criminal charges.
Can a creditor debit my checking account without my permission?
No. A creditor can only debit your account if you have signed an authorization form giving them permission. If they attempt to debit your account without authorization, report it to your bank and the CFPB. If a court has issued a judgment against you, the creditor can pursue a bank levy, but that requires a separate court order—not just access to your account number.
What is the difference between an authorized user and a joint account holder?
An authorized user can spend money from the account but does not own it and cannot close it. A joint account holder owns the account equally and can withdraw all the money or close it without the other person's consent. Both have access, but joint holders have more legal rights and responsibility.
How long does it take to add someone as an authorized user?
It usually takes one to three business days after you complete the bank's form. Some banks offer when ready approval through their online portal if both people are present and verified. Call your bank to ask about their specific timeline.
