If you are writing the check, sign the front on the printed line in the bottom-right corner. If you are receiving it, sign the back inside the endorsement area at the top. So the answer to where do I sign a check depends on which side of the transaction you’re on: the front signature authorizes your bank to pay, and the back signature (called an endorsement) is how the payee claims the money.
Signing the Front as the Check Writer
Your signature belongs on the pre-printed line at the bottom-right of the check. That signature is your instruction to the bank to release the amount you filled in. Under the Uniform Commercial Code, no one is legally responsible for a check unless they signed it or had an authorized representative sign for them.1Cornell Law School. Uniform Commercial Code 3-401 – Signature
The signature should reasonably match the one your bank recorded when you opened the account. A signature that looks significantly different from that record can be flagged, delayed, or rejected as a possible forgery. You don’t have to write your full printed name. What matters is consistency with the version your bank has on file.
Signing the Back as the Payee
When a check is made out to you, you endorse it by signing the back, within the first inch and a half at the top. Most checks print a box or set of lines labeled “Endorse Here” to show you exactly where. Federal check-processing standards reserve the rest of the back for bank stamps and routing information, so keeping your signature inside the marked area prevents scanning errors.2eCFR. 12 CFR 229.35 – Indorsements
Under the UCC, an endorsement is any signature other than the writer’s, placed on the check to transfer it, restrict payment, or accept liability as an endorser.3Cornell Law School. Uniform Commercial Code 3-204 – Indorsement Sign outside that zone and automated scanners may misread the check, or the bank may return it for correction.
Three Ways to Endorse
How you sign the back decides who can cash or deposit the check. Pick the option that matches what you’re about to do with it.
Blank Endorsement
A blank endorsement is just your signature, nothing else. Once you sign this way, the check becomes payable to whoever holds it, essentially like cash.4Cornell Law School. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement Save this one for the moment you’re standing at the teller window or ATM.
Restrictive Endorsement
A restrictive endorsement limits what can be done with the check. The most common version is “For Deposit Only” written above your signature, which means the check can only be deposited, not cashed at the counter. You can go further by adding your account number. Under the UCC, a bank or other party that ignores a restrictive endorsement and pays out the funds improperly can be liable for conversion.5Cornell Law School. Uniform Commercial Code 3-206 – Restrictive Indorsement This is the safest choice if you’re endorsing a check ahead of time.
Special Endorsement
A special endorsement hands the check to someone else. Write “Pay to the Order of” followed by that person’s name, then sign underneath. Only the named person can then negotiate the check, and they must add their own endorsement.4Cornell Law School. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement Some banks are cautious about third-party checks because of fraud risk, so the new recipient should check with their bank before trying to deposit one.
Endorsing for a Mobile Deposit
Most banks require a specific endorsement for checks deposited through a mobile app. Along with your signature, you typically need to write “For Mobile Deposit Only” underneath. Some banks also ask for your account number or the bank’s name. That restrictive language exists to keep the same check from being deposited twice.
Federal rules on remote deposit capture treat these endorsements as consequential: under Regulation CC, a bank that later accepts the original paper check with a restrictive endorsement inconsistent with how the check was already deposited can lose certain indemnity protections.6eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Follow your bank’s exact wording. Mobile deposits are commonly rejected for endorsements that are incomplete or don’t match the app’s instructions.
Signing a Check for a Business
If you’re signing on behalf of a corporation, LLC, or partnership, your signature still goes in the bottom-right corner on the front. What changes is that you need to show you’re signing as a representative, not personally. Adding your title next to your name (Treasurer, Manager, Authorized Signer) does that.
The distinction matters because the UCC provides that if your signature doesn’t clearly show you’re acting for an identified business, you can be personally liable on the check.7Cornell Law School. Uniform Commercial Code 3-402 – Signature by Representative A signature reading “Jane Smith, Treasurer, ABC Corp” leaves no room for doubt. Signing “Jane Smith” alone on a check with the business name preprinted above can invite a dispute over whether you meant to be personally on the hook. When you’re not sure, include the business name and your title alongside your signature.
Some accounts require two authorized signatures. Both signers have to sign the front before the check goes out, and the bank verifies each against the signer list from when the account was opened.
Checks Made Out to More Than One Person
When two people are named as payees, whether both have to endorse comes down to one word. If the check reads “John Smith and Jane Doe,” both must sign the back. If it reads “John Smith or Jane Doe,” either person can endorse and deposit it alone.8Cornell Law School. Uniform Commercial Code 3-110 – Identification of Person to Whom Instrument Is Payable
Stack the required signatures neatly inside the endorsement area. If the check uses neither word, only a comma between the names, banks typically treat it as “and” and require every listed payee to endorse.
If the Check Has Your Name Misspelled
You can still endorse a check that misspells your name. The UCC lets you sign using the name as written on the check, your correct name, or both.3Cornell Law School. Uniform Commercial Code 3-204 – Indorsement In practice, banks and check-cashing services often ask you to do both: sign the misspelled version first, then your correct name beneath it, so the paper trail connects the payee named on the check to you.
Stamps, Machines, and Electronic Signatures
A signature doesn’t have to be handwritten. The UCC recognizes signatures made manually or by a device or machine, including rubber stamps, electronic signatures, and thumbprints.1Cornell Law School. Uniform Commercial Code 3-401 – Signature Businesses that write large volumes of checks commonly use signature stamps or automated signing machines. The same allowance covers endorsements: a payee can use a rubber stamp reading “For Deposit Only” with an account number instead of writing it out each time.
If you use a signature stamp, keep it locked up. A stamped signature carries the same liability as a handwritten one, so anyone who gets hold of your stamp can authorize transactions from your account.
