You can sometimes mobile deposit a third-party check, but most banks either prohibit it outright or restrict it to established customers, and the ones that allow it require a specific endorsement and often hold the funds longer than usual. A third-party check is one made out to someone else who then signs it over to you, and while that transfer is legal, your bank decides whether its app will accept the deposit.
Why Banks Usually Reject These Deposits
Federal regulations let banks accept or reject any check submitted for deposit.1eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Mobile deposits of third-party checks get treated as high-risk because the bank cannot verify in real time that the original payee actually signed the back. Many of the largest national banks prohibit them through the app entirely. Others allow them only for customers with a solid account history.
Before you try, read your bank’s mobile deposit agreement in the app’s terms of service. Depositing a check that violates those terms can lead to the deposit being reversed, your mobile deposit privileges being suspended, or fees being charged to your account.
How to Endorse a Third-Party Check
Transferring a check to someone else requires a special endorsement, meaning one that names the new recipient.2Cornell Law School. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement Two people sign in the endorsement area on the back of the check:
- The original payee signs their name, then writes “Pay to the order of [your full name]” directly below the signature.
- You sign your own name below that, exactly as it was written on the “Pay to the order of” line.
- Beneath your signature, write “For mobile deposit only” and add your bank’s name or account number if your bank requires it. This restricts the check to a single digital deposit.
Every character has to be legible and fit inside the endorsement area. If any part is cut off, smudged, or unclear, the app’s automated review will reject the image before a person ever sees it. Some banks want slightly different wording or additional details like the date, so check the app’s own instructions.
Submitting the Deposit
Open the deposit feature in your bank’s app, select the account, and enter the exact dollar amount printed on the check. A number that doesn’t match can trigger a manual review or a rejection on its own.
Place the check on a dark, flat surface so the app can detect the edges and read the routing and account numbers along the bottom. Line up all four corners and the full endorsement area within the on-screen guides, capture the front and back, and confirm. A confirmation that the images were received is not the same as the deposit being approved.
How Long the Funds Are Held
Under federal rules, banks generally must make funds available by the second business day after deposit for local checks, or by the fifth business day for nonlocal checks.3eCFR. 12 CFR 229.12 – Availability Schedule
Third-party checks often trigger exception holds. When a bank has reasonable cause to doubt a check will clear, and an unverifiable third-party endorsement is a common reason, it can add up to five business days for local checks or six for nonlocal ones on top of the standard schedule.4eCFR. 12 CFR 229.13 – Exceptions A nonlocal third-party check could sit on hold for up to eleven business days total. Your bank has to notify you when it places an exception hold and tell you why.
If the Deposit Is Rejected
A declined mobile deposit leaves you with a few options:
- Take the check to a branch. A teller can verify the endorsement in person, which removes the reason the app turned it away. Bring photo ID, and bring the original payee if possible.
- Go to the bank whose name is printed on the check. That bank can often cash it directly because it can verify the drawer’s account and signature. Expect a fee if you don’t have an account there.
- Ask the original payee to deposit the check into their own account and send you the money through a transfer, payment app, or personal check.
If the rejection notice points to a specific fix, such as a missing “for mobile deposit only” line or a blurry image, you can correct it and resubmit. A check that has been rejected once and then redeposited may be subject to an exception hold with no standard availability timeline, so the funds could take longer to clear.4eCFR. 12 CFR 229.13 – Exceptions
Keep the Paper Check Until It Clears
The paper check still exists after the app accepts your deposit, and that creates a risk. If the same check gets deposited a second time, both deposits create separate demands against the same funds. Intentional double presentment can be prosecuted as bank fraud.
Don’t throw the check away right after the app confirms receipt. Hold it until the funds move from pending to available in your account. Most banks recommend keeping it at least 30 days. Once the deposit fully settles, write “VOID” across the front or destroy the check. Never take it to a branch or ATM after you’ve already submitted it through the app.
If the Check Bounces
If the check comes back unpaid because the writer’s account had insufficient funds, was closed, or the bank flagged the endorsement as invalid, your bank will reverse the credit. If you already spent the money, your balance can go negative and you can be charged overdraft fees on top of a returned-item fee.5HelpWithMyBank.gov. A Check I Deposited Bounced – Am I Liable for the Entire Amount?
The loss falls on you as the depositor. Your bank isn’t obligated to absorb it, and recovering the money means going after the person who signed the check over to you or the original check writer. Only accept third-party checks from people you trust, and leave the funds alone until the hold has passed.
Stale-Dated Checks
Banks are not required to honor a check presented more than six months after its written date.6Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old A bank may still process one in good faith, but it doesn’t have to. Automated mobile deposit systems routinely flag the issue date, so a check near or past six months old is unlikely to go through the app at all. Ask the check writer for a replacement with a current date before you try to deposit it.
