“And” means that everybody named on the check must sign. “Or” usually allows only one of the payees to sign.

‘And’ Checks Can Be Tricky

Banks have to verify the identity of everyone who signs the back of a check, “endorsing” it so it can be cashed or deposited. There’s hardly any risk if a check is made payable to two parties and you’re depositing the funds into an account that bears the same two names, but there’s a risk that one person will forge the other’s signature and run off with the money if somebody wants to cash the check.

Does Everyone Need To Sign Together? 

Some banks require that all the payees named on a check endorse it together at the same time, in front of a bank employee. Everyone must show valid identification to prove that they’re permitted to endorse that check. Other banks will accept a check when just one of the payees has an account with them. Banks are especially careful with checks that involve high dollar amounts. One person can often endorse and deposit without the hassle of getting everybody together if it’s just for a small amount, such as $5 or $10.

Deposits Are Easier

The process should be simpler if the plan is to deposit the check as opposed to cashing it. That’s especially true when all the payees hold an account together. For example, it might be a joint account for a married couple, and the check is written using those same two names. It might even be possible for one person to deposit the check without both signatures in this case.

‘Or’ Means Anybody

In most cases, just one party can sign checks made payable to multiple parties using the word “or.” For example, a check made payable to “Jane or Pat Doe” can be signed by either Jane or Pat. Certain situations might require the signatures of all payees, however.

What If It’s Not Clear?

Some checks don’t specify “and” or “or” anywhere. The answer isn’t as clear in this case. As far as the law is concerned, you can often treat the check as if it says “or.” The Uniform Commercial Code (UCC), which sometimes serves as a template for how states and banks handle these transactions, indicates that “ambiguous” checks can be negotiated by anybody named on the check.

Bank Policy Overrides

Your bank doesn’t have to follow the UCC guidelines. Banks can use extra caution with these checks to protect themselves from losses. Some banks have a policy requiring everyone to endorse the check when there’s any doubt about the check writer’s intentions. They might even require that everyone be present to sign in front of a bank employee, preventing you from just mailing it in or depositing it at an ATM. One option is to try your luck and simply attempt to deposit or cash a check with just one payee’s signature. The risk is that the bank will reject your deposit and require that you get the missing signatures before you re-deposit. That process can take several days, weeks, or even longer. A safer approach is to contact the banks involved (both the bank the check is drawn on, and the one to which you’re depositing it) and ask what they require. Don’t be surprised if you hear conflicting answers from different people—bank policies aren’t always clear or well-known.

You Can Always Try

In some cases, checks will be accepted with a single signature—even when bank policies require multiple signatures—because the missing signatures might go unnoticed. Ultimately, you have to decide what’s best for you. Weigh the alternatives, considering how easy it is to get everyone’s signature and whether you can tolerate delays if the bank wants more signatures.

Writing Checks to Multiple People

Keep in mind that you can make it relatively easy or difficult for the recipients of a check to deposit the funds if you’re writing one to more than one person. The right choice depends on what you hope to accomplish, how much you trust the two (or more) people, and other factors like legal and tax issues. “Or” makes it easy. Using “or” between names allows the most flexibility if you’re not worried about one of them secretly pocketing the funds. “And” keeps everyone informed. It’s better to use “and” if you want to be as certain as possible that everybody is aware of the check. This might (or might not) slow things down, but that could be a good thing.

Wedding Gifts

Choose carefully if you’re writing a check to newlyweds. One or both spouses might change their last name. Money is always a nice gift, but complications can arise if you write a check out to both of them using “and”:

One of them might change their name, and it will no longer match the name on the check.You might assume that one of them is changing their name, but that’s not accurate.

In many cases, newlyweds can deposit these checks even if the names don’t match up perfectly. Banks see this fairly often. But depositing the funds might require a trip to the branch or a few additional documents and phone calls. Write the check using “or,” or ask the couple how they prefer to receive gifts to make the deposit as easy as possible for them.
