How to Stop Payment on a Check or ACH Transaction

Be clear about which problem you have, because the fixes are different. A stop-payment order tells your bank to block one specific upcoming item — this check, or this scheduled debit. It is the right tool when a check is lost or was sent for the wrong amount, or when you know a particular ACH debit is about to post and you want to block it.

That is not the same as telling a merchant to quit charging you. If you want to end an ongoing subscription or recurring ACH agreement, you revoke the authorization you gave the company — covered in stopping an automatic ACH payment. And if an unauthorized charge has already posted, that is a dispute, not a stop payment — covered in disputing an unauthorized automatic payment. A stop-payment order is forward-looking: it blocks an item that has not been paid yet.

• Stop payment (this article): block a specific upcoming check or scheduled ACH debit at your bank.
• Revoke authorization: tell a merchant to stop charging you on a recurring agreement (see stopping an automatic ACH payment).
• Dispute: challenge a charge that already posted as unauthorized (see disputing an unauthorized automatic payment).

Contact your bank or credit union as soon as you decide you want to stop a check — by phone, online or mobile banking, or in person, depending on what your bank accepts. Give them the details that let them identify the exact check, and ask them to confirm the order is in place. Many banks let you start by phone or online, but several will ask you to follow up in writing, so be ready to put the request on paper the same day.

Even when an oral order is accepted, putting the request in writing protects you. A written, dated stop-payment order is your proof of when you asked and what you asked for, and it is what makes the six-month protection most reliable. Keep a copy of whatever you submit and note the confirmation number or the name of the representative who took the order.

• Your name and the account number the check is drawn on.
• The check number.
• The exact check date and the dollar amount.
• The payee — the name of the person or company the check is made out to.
• The reason, if asked (lost, stolen, wrong amount, disputed).

For checks, the CFPB explains that most states have laws under which a stop-payment request made in writing, before the check has been completely processed, keeps the check from being cashed for six months. In some cases the order can last up to a year, and some banks let you renew it before it expires. The practical takeaways are that the order is not permanent, and that a written request is what most reliably triggers the full protection period.

If you need to make sure a payment can never go through — for example, the check is lost and you cannot risk it surfacing later — the CFPB notes that the more permanent step is to close the account and open a new one, because a stop-payment order eventually lapses. Mark your calendar for the expiration date if the underlying problem is not resolved by then.

ACH debits — electronic payments pulled from your account, such as a scheduled loan payment or a one-off electronic withdrawal — run on different timing. Under federal Regulation E (12 CFR 1005.10(c)), you can stop payment of a preauthorized electronic fund transfer by notifying your bank orally or in writing at least three business days before the scheduled transfer date. Because of that lead time, you have to act early — a stop request the day a debit is set to post is usually too late.

Two rules matter here. First, the three-business-day deadline is measured before the scheduled date, so count backward from the transfer date. Second, if you give the order orally, the bank may require you to confirm it in writing within 14 days, and it must tell you that and give you the address to send it — if you miss that 14-day written confirmation, the oral order can stop being binding and the bank may resume processing the debits. Send the written confirmation promptly and keep your copy.

• Notify the bank at least three business days before the scheduled transfer date.
• An oral order may need written confirmation within 14 days, or it can lapse.
• Identify the payment: the company name, the expected amount, and the date.
• Blocking one scheduled debit does not cancel the underlying agreement — revoke the merchant's authorization separately.

Your bank or credit union may charge a fee to process a stop-payment order. Fees vary by institution and are commonly in the range of roughly $15 to $35, though some accounts waive or reduce them. This bank fee is separate from any cost of preparing the request document itself. Ask your bank for its current stop-payment fee so there are no surprises, and weigh it against the amount you are trying to stop.

There is one firm limit worth knowing: a stop payment only works on an item that has not already been paid. If the check has already cleared or the ACH debit has already posted, a stop-payment order cannot reverse it — at that point you are looking at a dispute or another remedy, not a stop payment. Certified checks, cashier's checks, and similar bank-guaranteed instruments generally cannot be stopped this way either, because the bank has already committed the funds.

Whether your bank requires it or simply accepts it, a written stop-payment order is the version that protects you. It records the date you asked, names the exact item, and gives the bank everything it needs to find and block the right check or debit. Keep it factual: identify the account, the check number or the ACH payment, the amount, the payee or originator, and state clearly that you are ordering payment stopped.

Submit it through whatever channel your bank accepts, keep a dated copy, and follow up to confirm the order is active. When you need to hand your bank a clean, complete document, you can generate a stop payment request form with the account, check, amount, and payee details laid out the way the bank needs them. Remember that stopping one item is not the same as cancelling a recurring charge or disputing a payment that already posted — those are separate steps covered in the related guides.

• Identify the account and the exact item (check number, or the ACH payment, amount, and date).
• Name the payee or the company pulling the debit.
• State plainly that you are ordering the bank to stop payment.
• Submit it on time — before a check clears, or at least three business days before an ACH debit.
• Keep a dated copy and confirm the order is in place.

A stop-payment order blocks one specific payment that has not gone through yet. For a check, contact your bank right away with the account, check number, date, amount, and payee; a written request made before the check clears generally holds for six months. For a scheduled ACH debit, notify the bank at least three business days before the transfer date, and confirm an oral order in writing within 14 days so it does not lapse. Expect a bank fee, know that the order is temporary and cannot reverse an item that already paid, and keep a dated copy of everything. If your real goal is to end a recurring charge or dispute one that already posted, use the right tool for that instead.
