One party can be held liable for overdrafts and debts on a joint account, even if the other person caused them
When you open a joint checking account, both account holders are legally responsible for everything that happens in that account — the full balance, all transactions, and any overdraft fees or negative balances. If one person overdraws the account, writes bad checks, or incurs fees, the bank can pursue either account holder for the full amount owed. The bank does not care who actually spent the money. Both names on the account mean both people are liable.
This liability extends beyond just the bank. If the account goes negative and the bank writes off the debt, a creditor or collection agency can pursue either account holder. If one person uses the account fraudulently or recklessly, the other person has no automatic protection just because their name is on the account. You are jointly and severally liable — meaning the bank can collect the entire debt from whichever person is easier to reach.
Key Takeaways
- Both account holders are legally responsible for the full balance and all overdraft fees, regardless of who caused them.
- A bank can pursue either account holder for the entire amount owed; they do not split liability between you.
- If one person overdraws the account or writes bad checks, the other person can be sued for the full debt.
- You can pursue the other account holder in small claims court or civil court to recover money they spent without permission, but the bank will not do this for you.
- Removing someone from a joint account requires their signature or a court order in most states.
How banks treat overdrafts on joint accounts
When an account goes negative, the bank sends a notice to the account address on file. That notice does not specify which person caused the overdraft — it simply states that the account is overdrawn and both parties are responsible. The bank will attempt to collect from whichever account holder they can locate or whose paycheck they can garnish.
If the account remains negative for 30 to 60 days, the bank typically closes the account and may refer it to a collection agency or pursue the debt themselves. At that point, either account holder can be contacted and sued. The bank is not required to prove who spent the money; they only need to show that the account went negative and that both people signed the account agreement.
Some banks offer overdraft protection, which links the account to a savings account or credit line. If one person triggers overdraft protection, both people are still liable for repaying whatever was borrowed. The protection prevents the account from going negative, but it does not change who owes the money.
What happens if one person spent the money without permission
If one account holder spent money or wrote checks without the other person's knowledge or consent, the person who did not authorize the spending is still liable to the bank. However, this does not mean you have no recourse. You can pursue the other account holder in small claims court or civil court to recover the money they spent.
To win a case like this, you will need to show that the other person spent the money, that you did not authorize it, and the amount involved. Bank statements, canceled checks, and transaction records are your evidence. The burden is on you to prove what happened — the bank will not investigate or take sides.
Even if you win a judgment against the other person, collecting it is separate from the bank's claim. The bank can still pursue you for the overdraft while you are pursuing the other account holder. You may end up paying the bank first and then trying to recover from the other person, which can take months or years.
Removing someone from a joint account to stop liability
If you want to stop being liable for future transactions, you need to remove the other person from the account or close the account entirely. Removing someone requires either their signature on a form or, in some cases, a court order. Most banks will not remove a person without their consent because both parties have equal rights to the account.
If the other person refuses to sign removal paperwork, you can close the account and open a new one in your name only. This stops future liability but does not erase past debt. If the account is overdrawn when you close it, you are still responsible for paying that balance, even after the account is closed.
Some states allow you to remove someone without their signature if you can show fraud or abuse, but this requires going to court first. You will need to file a petition, provide evidence, and get a judge's order before the bank will act. This process typically takes several weeks to several months.
Creditors and collection agencies pursuing joint account holders
If a joint account goes negative and the bank does not collect the full amount, they may sell the debt to a collection agency. That agency can then pursue either account holder for the full balance. They do not have to prove who spent the money — they only need to show that both people are on the account and that money is owed.
A collection agency can file a lawsuit against either account holder, garnish wages, or place a lien on property. If they win a judgment, they can pursue bank accounts, tax refunds, and other assets belonging to either person. The person being pursued can defend themselves by proving they did not authorize the spending, but this requires going to court.
If you receive a collection notice for a debt you did not create, respond in writing within 30 days. Request proof that you are actually liable — this forces the agency to show the account agreement and the debt itself. Do not ignore the notice; ignoring it makes it easier for them to win a default judgment against you.
Protecting yourself before opening a joint account
Before opening a joint account, understand that you are taking on full liability for the other person's spending and financial decisions. This is appropriate for spouses or long-term partners who share finances, but it is risky with adult children, business partners, or anyone else you do not fully trust.
If you need to share an account for a specific purpose — paying household bills, managing a business, or caring for an elderly parent — consider alternatives. A power of attorney lets one person manage another's finances without creating joint liability. A trust account can hold money for a specific purpose without making both people liable for the full balance.
If you do open a joint account, set clear rules about spending limits, what the account is used for, and how often you will review statements together. Check your statements weekly, not monthly, so you catch unauthorized spending quickly. The sooner you notice a problem, the sooner you can address it and limit the damage.
Frequently Asked Questions
Can I be sued for overdrafts my spouse caused without telling me?
Yes. Both account holders are liable for the full overdraft amount, regardless of who caused it. The bank does not investigate who spent the money — they pursue whichever account holder is easiest to reach. You can then sue your spouse to recover the money, but you have to do that separately from the bank's claim.
What if I remove my name from the account after it goes negative?
Removing your name does not erase your liability for debts that already exist. You remain responsible for any overdraft or negative balance that occurred while your name was on the account. The bank can still pursue you for that debt even after you are no longer a signer.
Does the bank have to prove who spent the money before collecting from me?
No. The bank only needs to show that the account went negative and that you signed the account agreement. They do not have to identify who made each transaction. Your liability is based on your name being on the account, not on your personal actions.
Can I freeze the account to stop the other person from spending?
Most banks require both account holders to agree to freeze an account. If the other person refuses, you cannot freeze it without a court order. Your faster option is to close the account entirely and open a new one in your name only, though you remain liable for any existing negative balance.
What should I do if the other person is spending recklessly?
Document every unauthorized transaction with bank statements and dates. Contact the other person in writing (email or letter) asking them to stop. If they continue, close the account, remove them, or pursue legal action. The longer you wait, the larger the potential debt and the harder it becomes to prove you did not authorize the spending.
