If two names are on a check, both people have to sign only when the names are joined by the word “and.” If the names are joined by “or,” or if there’s no conjunction between them at all, either person can sign and deposit the check alone. That one small word between the names controls everything.
The Rule That Decides It: “And,” “Or,” or Neither
Every state has adopted some version of the Uniform Commercial Code, and the UCC is clear on this. When a check is payable to two people “not alternatively” — that is, connected by “and” — it can only be negotiated by both payees together. Neither person acting alone counts as the rightful holder.1Justia. Ohio Revised Code 1303.08 (UCC 3-110) Identification of Person to Whom Instrument Is Payable Both payees must endorse the back of the check before any bank will process it.2Consumer Financial Protection Bureau.

When the names are joined by “or,” either payee can endorse and deposit independently. The other person doesn’t need to be involved. Tax refund checks issued to joint filers often work this way for exactly that reason: one spouse can handle the deposit if the other isn’t around.
The wording that trips people up is a check with no conjunction — just two names separated by a line break, a slash, or a comma. Under the UCC, when a check is ambiguous about whether it’s payable jointly or alternatively, the default is alternative. Either payee can endorse it alone, the same as if “or” appeared between the names.1Justia. Ohio Revised Code 1303.08 (UCC 3-110) Identification of Person to Whom Instrument Is Payable Some banks apply a stricter interpretation and still ask for both signatures when the wording is unclear, so don’t be surprised if a teller asks for the second endorsement anyway.
What Your Bank May Require Beyond the Law
Even when the law allows one signature, your bank may want more. Banks set their own policies on dual-payee checks, and those policies often go beyond the UCC minimum to cut down on fraud. For any check joined by “and,” most banks require both payees to appear in person at a branch with government-issued identification so a teller can watch each signature happen.2Consumer Financial Protection Bureau.

The check also has to be deposited into an account that includes at least one of the named payees. Trying to deposit a dual-payee check into an account that doesn’t belong to either person listed is a guaranteed rejection.
Mobile Deposit
Mobile deposit is where things go wrong most often. Many banks refuse to accept dual-payee “and” checks through their apps because a teller can’t verify both signatures in real time. The deposit may appear to clear initially and then get flagged during back-end review, which can mean a returned deposit fee and a hold on the funds. For any “and” check, the safer move is to visit a branch. Some banks do allow mobile deposit of “or” checks with a single endorsement, but the policy varies, so ask before you tap.
When the Payees Don’t Share an Account
When two payees don’t have a shared account, both need to endorse the check and then deposit it into one person’s account, with a separate transfer to settle up. Some banks will process the deposit if both payees come to the branch together, even if only one has an account there. What banks generally won’t do is split the check between two accounts at different institutions.
Special Cases That Change the Signing Rules
Insurance and Mortgage Company Checks
After a homeowner’s insurance claim, you may receive a check made out to you, your co-owner, and your mortgage company, all joined by “and.” Every named party has an interest in the property, and every payee has to endorse before the money moves.
Getting the lender’s endorsement isn’t as simple as mailing the check over. Most mortgage servicers run a “loss draft” process. For smaller claims, the lender may endorse and return the check fairly quickly. For larger claims, the lender deposits the funds into a controlled account and releases money in stages as repairs are completed and documented. Contact your servicer as soon as the check arrives and ask for their loss-draft paperwork; starting early is the single biggest thing you can do to avoid weeks of delay.
U.S. Treasury Checks
Checks drawn on the U.S. Treasury — tax refunds, Social Security payments, federal benefits — follow federal endorsement regulations on top of the UCC. Under 31 CFR Part 240, Treasury checks must be properly endorsed before a bank can process them.3eCFR. 31 CFR Part 240 – Indorsement and Payment of Checks Drawn on the United States Treasury The same “and” versus “or” rule applies: if the check says “and,” both payees sign.
When One Payee Has Died
A joint check joined by “and” creates a real problem when one payee has died, because the deceased person can’t endorse.
For Treasury checks, federal rules require the personal representative of the deceased payee’s estate — an executor or administrator — to endorse in that capacity. The endorsement has to show the representative’s role, in a form like “John Jones by Mary Jones, executor of the estate of John Jones.”4eCFR. 31 CFR 240.15 – Checks Issued to Deceased Payees The surviving payee still signs normally, and both endorsements have to be there.
For non-Treasury checks, the same principle applies under state law. If no estate has been opened — common when the amount is small — the fastest path is often to contact the issuer and ask them to reissue the check in the surviving payee’s name alone.
If the check uses “or,” none of this applies. The surviving payee can endorse and deposit it without involving the estate, because either payee was always entitled to negotiate the check alone.
If a Co-Payee’s Signature Was Forged
When a dual-payee check gets deposited with one signature forged, the bank is generally liable to the rightful payee for the full amount of the check.5HelpWithMyBank.gov. My Bookkeeper Forged the Endorsement on Checks. What Can I Do? The bank paid someone who wasn’t entitled to the money, and the loss starts with the bank. The forger can also be pursued separately.
You have to act, though. Under the UCC, you’re expected to review your bank statements with reasonable promptness and notify the bank of unauthorized activity when you find it. For unauthorized endorsement claims against a bank, the UCC generally sets a three-year window from when the cause of action arises.6Cornell Law School. UCC 4-111 Statute of Limitations The UCC’s general statute of limitations for actions on negotiable instruments also uses three-year periods for most claims, with the trigger date depending on the type of instrument and claim.7Cornell Law School. UCC 3-118 Statute of Limitations Some states modify these deadlines, particularly where fraud is involved and discovery rules extend the filing period.
Waiting is never the strategy. Banks are more cooperative and recovery is more likely when you report the problem quickly.
