Cashier's checks do not expire, but banks may stop honoring them after a certain time

A cashier's check itself never officially expires. The bank that issued it remains legally responsible for the funds indefinitely. However, most banks will not cash or deposit a cashier's check that is more than six months old without verification, and some refuse them outright after that point. The older the check, the harder it becomes to use it, even though the bank's obligation to pay does not technically end.

The six-month window is a standard practice across most U.S. banks, but it is not a law. Individual banks set their own policies. Some banks honor checks older than six months if you contact them directly and confirm the check is still valid. Others treat any check older than six months as stale and will not process it without a new check from the issuing bank. The receiving bank — the one you are trying to deposit it into — may also refuse it based on their own rules.

If your cashier's check is older than six months and a bank refuses it, you can contact the bank that issued the check and ask them to issue a replacement or confirm the original check's validity. This process can take several business days, and the issuing bank may charge a fee to reissue the check.

Key Takeaways

  • Most banks will not cash or deposit a cashier's check older than six months without contacting the issuing bank first.
  • The six-month guideline is a banking practice, not a legal requirement, so policies vary by bank.
  • If a bank refuses your check, you can contact the issuing bank to request a replacement or written confirmation that the check is still valid.
  • The longer you wait to use a cashier's check, the more likely you will face delays or need to obtain a new one.
  • Keeping your cashier's check in a safe place and using it within a few months reduces the risk of complications.

Why banks treat old cashier's checks with caution

The six-month threshold comes from banking standards set by the American Bankers Association, though it is not federal law. Banks use this timeframe to reduce fraud risk and to manage their accounting. A check that sits unused for months raises questions: Was it lost? Stolen? Already cashed under a different name? The longer the gap between issue and deposit, the harder it is for the bank to verify that nothing suspicious happened in between.

When you deposit a check, the receiving bank contacts the issuing bank to confirm the funds exist and the check is legitimate. For very old checks, the issuing bank may have already closed the account or purged records, making verification difficult. Some banks also worry that an old check could be a duplicate — that you already cashed it once and are trying to cash it again.

The issuing bank is still legally bound to honor the check, but they are not required to do so when ready or without investigation. If you show up with a two-year-old cashier's check, the bank can ask you to wait while they research whether it was already paid.

What happens when you try to deposit an old cashier's check

If your cashier's check is less than six months old, most banks will process it like any other check. You can deposit it at an ATM, through mobile deposit, or in person at a teller window. The funds typically appear in your account within one to three business days.

If your check is between six months and one year old, the receiving bank may accept it but flag it for manual review. A teller might ask you questions about the check: Who issued it? Why are you depositing it now? Do you have any documentation? This review can add several business days to the process. Some banks will refuse to process it at all and tell you to contact the issuing bank.

If your check is older than one year, most banks will refuse to deposit it without written confirmation from the issuing bank that the check is still valid and has not been paid. At this point, your best option is to contact the bank that issued the check and ask for a replacement.

How to handle a cashier's check that is too old

Contact the bank that issued the check as soon as you realize it may be too old. You will need the check number, the amount, and the date it was issued. Have the check in front of you when you call. The bank can tell you whether they will still honor it or whether you need a replacement.

If the issuing bank agrees to honor the old check, ask them to provide written confirmation. Take this letter to the bank where you want to deposit the check. The receiving bank can then process the deposit with the issuing bank's verification on file.

If the issuing bank will not honor the old check or if the account has been closed, you can ask for a replacement check. The issuing bank may charge a fee for this service, typically between $10 and $25. The replacement check will have a new issue date and will be treated as a current check by any bank you deposit it into. This process usually takes five to ten business days.

Preventing problems with cashier's checks

The simplest way to avoid issues is to use your cashier's check within 30 days of receiving it. At this point, no bank will question its age. If you cannot use it when ready, store it in a safe place — a safe deposit box, a home safe, or with important documents. Do not leave it loose in a wallet or desk drawer where it could be lost or damaged.

If you receive a cashier's check and know you will not use it for several months, consider asking the person or business issuing it to hold off on purchasing the check until you are ready. This is not always possible, but it eliminates the aging problem entirely.

Write down the check number, amount, and issue date in a separate location. If the check is lost or stolen, this information helps the issuing bank cancel it and issue a replacement. Many banks require a police report or affidavit of loss before they will replace a missing cashier's check, so having documentation of what you lost speeds up the process.

State laws and variations in check-handling rules

Most states follow the Uniform Commercial Code (UCC), which governs how checks are handled. Under the UCC, a bank can refuse to pay a check that is more than six months old, but they are not required to. This means state law does not force banks to honor old checks — it straightforward allows them to refuse without penalty.

A few states have specific rules about how long banks must hold funds or how long they must attempt to process checks, but these rules do not override the six-month guideline for stale checks. Your state's banking regulator can tell you the specific rules that explore to banks in your state, but in practice, the six-month standard applies almost everywhere.

If you are depositing a cashier's check across state lines — for example, a check issued by a bank in one state and deposited in another — both states' rules could explore. The receiving bank will follow their own state's rules, which typically means the six-month guideline still applies.

Frequently Asked Questions

Can a bank refuse to cash a cashier's check that is three months old?

No. At three months, the check is well within the standard six-month window, and any bank should cash or deposit it without hesitation. If a bank refuses a three-month-old cashier's check, contact the issuing bank or ask to speak with a manager at the receiving bank, as this would be unusual.

What if I lost my cashier's check?

Contact the issuing bank when ready and report it lost. You will likely need to sign an affidavit stating that the check is missing and has not been cashed. The bank can then cancel the original check and issue a replacement. This process can take one to two weeks, and the bank may charge a fee. Some banks require a police report before they will replace a lost check.

Can I deposit a cashier's check that is nine months old?

You can try, but the receiving bank may refuse or require verification from the issuing bank first. At nine months, the check is considered stale. Contact the issuing bank and ask them to provide written confirmation that the check is still valid. Bring this confirmation to the receiving bank along with the check.

Do cashier's checks expire if I never use them?

Cashier's checks do not expire in the legal sense — the issuing bank remains responsible for the funds. However, after six months, banks treat them as stale and may refuse to process them. If you never use the check, the funds remain in the issuing bank's account indefinitely, but accessing them becomes increasingly difficult as time passes.

Can I get my money back if my cashier's check is too old to use?

Yes. If the issuing bank will not honor the old check and will not issue a replacement, you can ask for a refund of the original amount. The bank should return the funds to the account that paid for the check originally. This process may take several business days and could involve fees, depending on the bank's policy.
