To sign a check, put your signature on the line at the bottom-right corner of the front if you’re the one writing it, or on the top section of the back if you’re depositing one made out to you. Those are the two signing spots, and each one does a different job: the front signature authorizes your bank to pay, and the back signature (the endorsement) lets your bank accept the check for deposit or cash. Learning how to sign a check correctly in both places, and picking the right style of endorsement, keeps your money moving and closes off the most common ways checks get rejected or misused.
Use a pen with permanent ink, black or dark blue. Banks routinely reject checks signed in pencil or erasable ink because those marks can be altered later. Keep your signature consistent with the one your bank has on file, since both tellers and automated verification systems compare the two.
Signing the Front When You Write a Check
Your signature goes on the line at the bottom-right corner of the front. That signature is your authorization for the bank to withdraw funds from your account. Under the Uniform Commercial Code, no one is liable on a check unless they signed it personally or through an authorized representative.1Legal Information Institute. Uniform Commercial Code 3-401 – Signature
Fill in every other field first: the date, the payee’s name, and the amount in both numbers and words. Sign last. A blank field on a signed check is an opening for someone to write in a larger amount or a different payee, and because your signature is genuine, your bank may honor the altered check.
Signing the Back to Deposit a Check
When you receive a check, you endorse the back before depositing or cashing it. The endorsement area runs across the top of the back of the check. Federal banking rules limit payee endorsements to roughly the first inch and a half, leaving the rest of the back for bank processing stamps. Writing below that zone can interfere with processing and get the check returned.
You have three main ways to endorse, and the one you pick controls what happens if the check is lost or stolen after you sign.
Blank Endorsement
A blank endorsement is just your signature, nothing else. It’s the fastest option, but it turns the check into the equivalent of cash. Under the Uniform Commercial Code, a check endorsed in blank becomes payable to whoever holds it and can be transferred by possession alone.2Legal Information Institute.

Restrictive Endorsement (For Deposit Only)
A restrictive endorsement limits what can be done with the check after you sign. Write “For Deposit Only” above your signature, and add your account number underneath if you want an extra layer of specificity. This blocks anyone from cashing the check at a teller window; it can only be deposited into the account you named.3Consumer Financial Protection Bureau. What Does It Mean for a Check to Be Indorsed for Deposit Only Under the Uniform Commercial Code, an endorsement using the words “for deposit” or “for collection” directs the bank to handle the check only for that purpose.4Legal Information Institute. Uniform Commercial Code 3-206 – Restrictive Indorsement This is the safest option when you’re mailing a check to your bank or handing it off to someone else to deposit for you.
Mobile Deposit Endorsement
Many banks require specific wording when you deposit through their app. The typical format is “For Mobile Deposit Only,” sometimes followed by the bank’s name or your account number, written above your signature. Check your bank’s mobile deposit instructions before you sign, because requirements vary; some banks will reject a mobile deposit that carries only a blank endorsement or leaves out the bank’s name. After you photograph both sides, write “VOID” across the paper check or hold onto it in a secure spot until you’ve confirmed the deposit cleared.
Signing a Check Over to Someone Else
You can transfer a check you received to a third party with a special endorsement. In the endorsement area, write “Pay to the order of” followed by the new recipient’s full name, then sign underneath. The new recipient then endorses below your signature before depositing.2Legal Information Institute. Uniform Commercial Code 3-205 – Special Indorsement, Blank Indorsement, Anomalous Indorsement
Know that many banks are reluctant to accept these. A bank sets its own policy on third-party checks and is not legally required to take them.5HelpWithMyBank.gov. Can the Bank Refuse to Cash an Endorsed Check If the bank does accept the check, it may ask the original payee to appear with identification. Call the depositing bank first to confirm its policy before you sign anything over.
Signing on Behalf of a Business
How you format a signature on a business check controls whether you could be held personally liable. Under the Uniform Commercial Code, if your signature clearly shows you’re signing on behalf of the business rather than in your personal capacity, you’re generally shielded from personal liability.6Legal Information Institute. Uniform Commercial Code 3-402 – Signature by Representative
On checks drawn from a business checking account where the company name is already printed on the check, signing your own name as an authorized signer is usually enough, because the check itself identifies the business. For any other financial document signed on the company’s behalf, the safer practice is to write the business name, your signature, and your title (such as “President” or “Treasurer”) so there’s no ambiguity. Signing without any indication of your representative role can expose you to personal liability for the amount on the check.6Legal Information Institute. Uniform Commercial Code 3-402 – Signature by Representative
When the Payee Name Is Misspelled
If someone writes you a check and misspells your name, you can still deposit it. The Uniform Commercial Code allows you to endorse using the misspelled name as it appears on the front, your correct legal name, or both.7Legal Information Institute. Uniform Commercial Code 3-204 – Indorsement Most banks prefer both, in order: the misspelled version first, your correct name below it. That creates a clear paper trail linking the check to you. If the misspelling is severe enough that the bank questions the endorsement, ask the issuer to reissue the check.
Fixing a Signing Mistake
If you flub a signature or fill in the wrong information on the front, the safest move is to void the whole check and write a new one. Write “VOID” in large letters across the front so it can’t be used. Crossing out and initialing a correction is sometimes accepted, but many banks treat visible alterations as a red flag and may reject the check. For an endorsement error on the back of a check you received, contact the person who wrote it and ask for a replacement rather than layering fixes on the paper you have.
