Signing the back of a money order endorses it and releases the funds, but a plain signature with nothing else written next to it turns the money order into bearer paper — meaning whoever physically holds it can cash it. That is why how and when you sign matters as much as the signature itself. A few extra words above your name, and waiting until you are at the teller window or looking at your mobile deposit screen, protects you from losing the money if the paper goes missing.
What Your Signature Legally Does
Before you sign, a money order is “order paper” under the Uniform Commercial Code, and only the person named on the front can collect the funds. A blank endorsement — your signature alone, with no restriction — converts it into “bearer paper,” payable to whoever presents it, regardless of the name on the front.1Cornell Law Institute.

This is why timing matters. Endorsing in the parking lot before walking into the bank creates a window where anyone who picks the money order up off the ground could theoretically cash it. The safest practice is to wait until you’re at the teller window, or until your mobile deposit app is open, before signing anything.
The Safer Way to Sign
Rather than signing your name alone, add language that limits what can be done with the money order. Writing “For Deposit Only” followed by your account number above your signature restricts the instrument so it can only be deposited into that specific account. A bank or credit union that accepts a money order with this endorsement is generally bound to follow the restriction and deposit the funds accordingly.2Cornell Law Institute. Uniform Commercial Code 3-206 – Restrictive Indorsement
If you plan to deposit through a mobile banking app, many banks require you to write “For Mobile Deposit Only” below your signature instead. That language helps the bank flag the item as a remote deposit and prevents the same money order from being deposited twice, once through the app and again at a teller window. Check your bank’s specific instructions, as some require the bank name alongside the mobile deposit language.
If You Already Signed Too Early
People accidentally endorse money orders all the time, often confusing the purchaser’s signature line on the front with the endorsement area on the back, or simply signing out of habit before heading to the bank. If you’ve already signed but haven’t deposited yet, you have a practical fix. Write “For Deposit Only” and your bank account number directly above your signature. That converts the blank endorsement into a restrictive one, so the money order can only be deposited into your account rather than cashed by a random holder.1Cornell Law Institute.

Do not try to cross out, erase, or white-out your signature. Any visible alteration will likely cause the money order to be rejected outright. If you are not planning to deposit right away and have already endorsed it, contact the issuer. For USPS money orders, you can request a replacement for a $21 processing fee, though the investigation can take up to 60 days.3USPS. Sending Money Orders
Signing a Money Order Over to Someone Else
If you want to transfer the money order to another person instead of cashing it yourself, write a special endorsement on the back: “Pay to the order of” followed by the new recipient’s full name, then sign underneath. This creates a clear record that you’ve transferred your rights to the funds.1Cornell Law Institute. Uniform Commercial Code 3-205 – Special Indorsement; Blank Indorsement; Anomalous Indorsement
Here is where most people run into trouble. Many banks and check-cashing stores refuse to accept third-party endorsed money orders. A bank sets its own policy on whether to accept these and has no legal obligation to honor one.4Office of the Comptroller of the Currency. Can the Bank Refuse to Cash an Endorsed Check? Even banks that do accept them often require the original payee to be present at the window to verify their signature. If the amount is small, buying a new money order in the other person’s name is usually less hassle than negotiating a third-party endorsement.
When the Name on the Front Is Misspelled
If the sender misspelled your name, the UCC gives you flexibility. You can endorse using the misspelled name exactly as it appears, your correct legal name, or both. In practice, most banks prefer to see both: first sign using the name written on the money order, then sign again with your actual legal name underneath. A bank or check-cashing store accepting the money order can require both signatures before releasing funds.5Cornell Law Institute. Uniform Commercial Code 3-204 – Indorsement
If the error is severe enough that the names don’t look related at all, expect pushback. Bringing a government-issued ID that matches your real name will help, but some institutions may still refuse the money order. In that situation, the simplest path is to ask the sender to request a replacement from the original issuer with the correct spelling.
If a Signed Money Order Is Lost or Stolen
A blank-endorsed money order that goes missing is essentially lost cash. Anyone who finds it can attempt to cash it. That is why endorsing only at the point of deposit matters so much. If the worst happens, your options depend on the issuer.
For USPS money orders, you can file for a replacement, but the process is not fast. You will need the receipt from your original purchase and the money order’s serial number. USPS charges a $21 processing fee, and confirming whether the money order has already been cashed can take up to 30 days. The full investigation may stretch to 60 days.3USPS. Sending Money Orders
Western Union follows a similar process. You submit a claim with the 11-digit serial number, the purchase amount, and proof of purchase such as the receipt or the original money order stub. If you don’t have proof of purchase, Western Union will conduct a search and notify you of results within two to four weeks. Either way, a refund is only possible if the money order hasn’t already been cashed.6Western Union. Money Order Request Form
Keep your purchase receipt until you have confirmed the money order was successfully deposited or cashed. The receipt is your only proof of ownership if something goes wrong, and without it, recovery becomes far more difficult.
