On the back of a check, sign inside the 1.5-inch strip along the short edge that sits on the left when you look at the check from the front. That strip is usually marked with lines, an “X,” or the words “Endorse here,” and where to sign on the back of a check is fixed by federal rule: everything below that 1.5-inch band is reserved for bank processing marks. What you write alongside your signature — nothing, “for deposit only,” or “pay to the order of” — decides whether the check can be cashed, only deposited, or passed to someone else.
The Exact Spot to Sign
Federal Reserve regulations reserve the back of every check for endorsements and bank processing stamps. Under Appendix D to 12 CFR Part 229, your signature and any accompanying instructions must fit entirely within the 1.5-inch area measured from the trailing edge of the check, which is the left side when you view the check from the front.1Federal Register. Availability of Funds and Collection of Checks The space below that 1.5-inch zone is reserved for bank stamps, routing numbers, and processing marks used by the Federal Reserve system. If your writing bleeds into that lower area, the depositary bank can be held liable for delays caused by an unreadable endorsement, and your check may be returned.
Most pre-printed checks make this easy. Look for the line or box labeled “Do not write, stamp, or sign below this line” and keep your writing above it. When you flip the check over, orient it so the trailing edge is at the top. That top strip is your endorsement area.
Signature Only
The simplest option is a blank endorsement: you sign your name and nothing else. Under the Uniform Commercial Code, a blank endorsement turns the check into a bearer instrument, meaning anyone who physically holds it can cash or deposit it.2Legal Information Institute. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement That makes a blank-endorsed check as risky as cash. If you lose it or it gets stolen, whoever finds it can potentially collect the funds.
Because of this risk, don’t sign a check until you’re at the bank, at an ATM, or ready to submit a mobile deposit. If you must endorse ahead of time, use a restrictive endorsement instead.
For Deposit Only
Writing “For deposit only” above your signature creates a restrictive endorsement. It tells the bank the check can only be deposited into an account, not cashed over the counter. Adding your account number beneath the phrase ties the check to a specific account and adds another layer of protection.3Cornell Law School. Uniform Commercial Code 3-206 – Restrictive Indorsement
Under UCC 3-206, a bank that pays out a restrictively endorsed check in a way that contradicts the endorsement — handing over cash when the check says “for deposit only,” for example — can be liable for conversion. That makes a restrictive endorsement the safest choice any time you aren’t handing the check directly to a teller.
Signing a Check Over to Someone Else
A special endorsement transfers a check to a different person. Write “Pay to the order of [full name of the new recipient]” in the endorsement area, then sign your name below that line. The check then becomes payable only to the person you named, and that person must also endorse it before depositing or cashing it.2Legal Information Institute. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement
Many banks are reluctant to accept third-party checks. A bank is not legally required to accept a specially endorsed check and can set its own policy on whether to honor one.4HelpWithMyBank.gov. Can the Bank Refuse to Cash an Endorsed Check? If the bank does accept it, it may require the original payee to be present to verify the endorsement signature. Call the depositing bank ahead of time to confirm it will accept the check before going through the endorsement process.
Mobile Deposit Wording
Most banks require extra language when you deposit a check through a mobile app. The typical requirement is to write “For mobile deposit only at [name of your bank]” along with your signature in the endorsement area. This wording prevents the same check from being deposited a second time at a different institution, a common form of fraud with digital deposits.
These requirements come from individual bank policies rather than a single federal rule, so the exact wording varies. Some banks will reject a mobile deposit if you leave out the institution name or use the wrong phrasing. Check your banking app before endorsing; most apps display the required language on the deposit screen.
Checks Made Out to Two or More People
When a check is written to more than one payee, the connecting word between the names decides who has to sign.
- “And,” or no connecting word at all, means every named payee must endorse the check. If one signature is missing, the bank will reject it.
- “Or” means any single named payee can endorse and deposit the check alone.
The Uniform Commercial Code draws this distinction under its rules for instruments payable to two or more persons.5Legal Information Institute. Uniform Commercial Code 3-110 – Identification of Person to Whom Instrument Is Payable If the check uses unclear language like “and/or,” most banks treat it as “or” and accept a single endorsement, but policies vary. When in doubt, have all payees sign.
If Your Name Is Misspelled on the Front
If the check writer misspelled your name, used a nickname, or used your maiden name, endorse the check twice. First, sign the name exactly as it appears on the front of the check, misspelling and all. Directly below that, sign your correct legal name. Two signatures let the bank match the endorsement to the payee line and to the name on your account.6Legal Information Institute. Uniform Commercial Code 3-204 – Indorsement
Signing for a Business
When a check is payable to a business, an authorized person endorses it on the organization’s behalf. The proper format protects the signer from becoming personally liable for the check amount. Write the business name exactly as it appears on the payee line, followed by the word “by,” your signature, and your title, such as “Owner,” “Treasurer,” or “Authorized Agent.”
A proper business endorsement might read:
ABC Company
By: Jane Smith, Treasurer
For Deposit Only
Acct #XXXXXXX
Under UCC 3-403, if you sign a check on behalf of a business without clearly indicating your representative capacity — meaning you leave off the business name or your title — you may be held personally obligated on the instrument. Many businesses use a rubber endorsement stamp to keep every deposit consistent, and adding “For deposit only” with the account number is standard practice.
Signing a Check Payable to a Deceased Person
When a check is made payable to someone who has died, an executor or administrator of the estate can endorse it, provided the right to the payment did not end with the payee’s death. Federal regulations require the endorsement to show the capacity of the person signing. The standard format is:
“John Jones by Mary Jones, executor of the estate of John Jones”7eCFR. 31 CFR 240.15 – Checks Issued to Deceased Payees
When a financial institution receives a check endorsed this way, the Treasury will pay it without requiring documentary proof of the executor’s authority upfront. For checks not issued by the federal government, such as personal checks or insurance payments, the bank will likely ask you to present letters testamentary or other court documents proving your appointment as executor.
Signing a Check Made Out to a Minor
Children generally cannot open bank accounts or negotiate checks on their own. If a check is payable to a minor, a parent or legal guardian typically endorses it by signing the child’s name, then signing their own name with a notation such as “parent of [child’s name].” Many banks require the parent to deposit the check into a custodial or joint account rather than cash it. Call your bank ahead of time to confirm what documentation it requires; some institutions ask for a birth certificate or other proof of the parent-child relationship.
When a Bank Can Refuse Your Endorsement
Banks have broad discretion to reject checks that raise concerns. Common reasons a bank may refuse to process an endorsed check include:
- Third-party checks, because banks are not legally obligated to accept checks endorsed over to a new payee.4HelpWithMyBank.gov. Can the Bank Refuse to Cash an Endorsed Check?
- Suspected alterations, such as names crossed out and rewritten, white-out on the endorsement area, or ink that doesn’t match.
- Endorsements written outside the 1.5-inch zone, which can make the check unprocessable by automated systems.
- Missing signatures on multi-payee checks, such as a check payable to “John and Jane” with only one signature.
- A non-customer presenting the check, since banks routinely decline to cash checks for people who don’t hold an account at that institution, unless the check is drawn on an account there.
If your endorsement is refused, ask the teller what specifically needs to be corrected. Often the fix is simple: adding a missing signature, providing identification, or depositing the check instead of cashing it.
