What happens if you deposit a check without signing the back?
If you forget to endorse a check, the bank may reject the deposit, ask you to add the endorsement or handle it under its own procedure. The exact result depends on the bank and deposit method, so check the bank’s instructions.

Use CFPB check guidance if you need to understand endorsement or a check-related dispute.
Read CFPB check-endorsement guidanceWhat does endorsing a check do?
Endorsing a check means signing or otherwise completing the endorsement area on the back according to the bank’s requirements. A common restrictive endorsement is “for deposit only” followed by the payee’s signature, which the CFPB says is intended to restrict how the check can be used.
However, a missing signature does not necessarily mean that money has vanished or that the check is worthless. The bank may have procedures that allow a missing endorsement to be corrected, or it may simply reject the deposit until the check is endorsed properly.
What if you used mobile deposit?
Mobile deposits can have extra endorsement instructions, and different banks may require particular wording in the endorsement area. Some banks tell customers to write a specific phrase for mobile deposits. Others may review the image and ask for a corrected deposit.
Follow the deposit agreement for the bank you used. Do not assume that an endorsement rule from one bank applies identically to another.
What happens if the bank rejects the deposit?
The practical result is usually that the bank does not credit the deposit or asks you to correct the problem. Contact the bank before depositing the same check repeatedly, because duplicate submissions can create a separate problem.
If you still have the original check, ask the bank whether you should endorse it and submit it again. Keep any rejection message or receipt in case you need to show what happened.
What if I also made a mistake writing the check?
Do not try to “fix” a check by altering the amount or payee unless the bank that issued it confirms what should be done. A mistake on the front of the check can affect whether it is negotiable or paid.
If you wrote the check yourself and made an error, your bank may tell you to void it and issue a replacement. If someone else wrote it to you, contact the issuer if a replacement is needed.
What if the check is made out to two people?
The wording on the front matters. CFPB guidance says a check made payable to two people together generally needs both signatures before the bank or credit union cashes or deposits it, while a check payable to one person “or” another can generally be handled by either person.
That is why you should read the payee line carefully before assuming one signature is enough.
Is “for deposit only” safer?
It can restrict the way the check is handled. The CFPB describes “for deposit only” plus the payee’s signature as a restrictive endorsement intended to limit the check to deposit into the account.
It is especially useful when a check is being deposited through a bank process that asks for that wording. But the bank’s own instructions take priority, so follow them exactly.
What if you lose the check before endorsing it?
If you lose a check written to you before endorsing it, the CFPB says you should ask the person who wrote it to stop payment, and you can ask for a replacement check. The key is to stop the lost check being negotiated by someone else.
This is different from a check already deposited and later lost. Keep a record of what stage the check had reached.
What if I accidentally deposit the same check twice?
Tell the bank immediately. Duplicate deposits can be corrected, but you should not spend funds based on the second credit. The bank may reverse the duplicate item after detecting it.
Keep the original check and the deposit confirmations until the transaction is fully settled. A clean paper trail makes the correction easier.
The practical answer
For a forgotten endorsement, check your bank’s deposit status first. If the bank asks for an endorsement, follow the exact instruction and avoid resubmitting the item multiple times. A missing signature is usually a procedural problem, not proof that the payment has been lost forever.
Worked example
Illustrative check example: suppose a check is for $2,500. The account holder attempts a mobile deposit without endorsing the back, and the bank rejects the image for that reason.
- Check face value: $2,500.
- Amount deposited after correction: $2,500.
- Difference: $2,500 − $2,500 = $0.
The figures are illustrative. The important point is that the check amount itself has not changed merely because the endorsement was missing. The bank may simply require the endorsement to be corrected before it will accept the item.
The check amount is still $2,500 in the example. The missing endorsement affects whether the bank accepts the item; it does not by itself change the amount written on the check.

Can I deposit a check without signing the back?#
The bank may reject it, request a proper endorsement or process it under its own deposit rules. Endorsement requirements differ, especially for mobile deposits, so follow the instructions from the bank or credit union that is accepting the check. Follow your bank’s own endorsement instructions exactly.
What if I forgot to endorse a check and it already shows as deposited?#
Check the deposit status and your bank’s messages. A visible credit does not remove the need to follow any endorsement or verification request from the bank. Keep the check until the deposit is fully settled. Follow your bank’s own endorsement instructions exactly.
What does ‘for deposit only’ mean on a check?#
It is a restrictive endorsement. The CFPB says writing “for deposit only” and signing the check should restrict it to deposit into your account, rather than being freely cashed or transferred. Follow your bank’s own endorsement instructions exactly. Follow your bank’s own endorsement instructions exactly.
Do both people have to sign a check made out to both of them?#
Generally, yes when the payee line names both people together. A check payable to “Pat and Chris” generally needs both signatures, while a check payable to “Pat or Chris” can generally be signed by either person. Follow your bank’s own endorsement instructions exactly.
What if I lose an unsigned check?#
The CFPB says to ask the person who wrote the check to stop payment so another person cannot cash it, and you can request a replacement. Keep evidence of the original check details if available. Follow your bank’s own endorsement instructions exactly.
Can I deposit the same check twice by mistake?#
Tell your bank immediately if you think that happened. Do not spend the extra money. The bank can investigate and reverse the duplicate item, and keeping both deposit confirmations can help resolve the error. Follow your bank’s own endorsement instructions exactly.
