Most people can open a joint account, but banks have specific requirements and some relationships carry restrictions

You do not need to be married to open a joint account. Banks will let two or more people own one account together, but they set their own rules about who qualifies. The main requirements are age (usually 18 or older), a valid ID, and proof of address. Some banks require both account holders to apply in person; others allow one person to add someone later. A few banks restrict joint accounts to spouses or domestic partners, though most do not.

The catch is that banks treat joint account holders as equals by default. Both people can withdraw all the money, both are responsible for overdrafts, and both names appear on statements and tax forms. If you want different access levels—one person can deposit but not withdraw, for example—you will need a different account structure, and not all banks offer those options.

Key Takeaways

  • You must be at least 18 years old and provide a valid government ID and proof of address to open a joint account at most banks.
  • Joint account holders have equal access to all funds and equal responsibility for overdrafts, regardless of who deposited the money.
  • Some banks require both account holders to sign in person at a branch, while others let one person add a co-owner online or by mail.
  • A few banks restrict joint accounts to married couples or registered domestic partners, so check your bank's policy before you start the process.
  • If you need unequal access or limited withdrawal rights, you may need a power of attorney, guardianship, or a different account type instead of a joint account.

Age and identification requirements

You must be at least 18 years old to own a bank account in your own name or as a joint owner. Some banks allow minors to be added to a parent's account as a secondary user, but that is different from a true joint account—the minor does not own it, and the parent retains full control.

Both account holders need to provide a valid government-issued ID. A driver's license, passport, or state ID card works. The bank will also ask for proof of address, usually a recent utility bill, lease, or mortgage statement. If you are opening the account in person, bring originals. If you are opening it online or by mail, you may need to upload images or have the documents notarized, depending on the bank.

Some banks run a background check through ChexSystems, a banking history database. If you have been flagged for fraud or unpaid overdrafts at another bank, this can block you from opening a new account. You can request your ChexSystems report for free once a year at www.chexsystems.com.

How banks handle joint account ownership

When two people open a joint account, the bank creates one account with two owners. Both names go on the account, both get debit cards (if it is a checking account), and both can see all transactions. This is called joint tenancy with rights of survivorship in most cases, which means if one owner dies, the surviving owner automatically owns the full balance—it does not go through probate or the deceased person's estate.

Some banks offer tenancy in common instead, where each owner's share goes to their estate when they die, not automatically to the other owner. You have to ask for this explicitly; it is not the default. A few banks do not offer it at all.

The critical point: both owners have equal legal rights to every dollar in the account. One person cannot lock the other out, and one person cannot claim their deposits are separate property. If one owner withdraws all the money, the other owner has no legal recourse against the bank—the bank did nothing wrong. Your recourse is against the other person, through small claims court or civil court.

Banks that restrict joint accounts to married couples

Most major banks—Chase, Bank of America, Wells Fargo, Citibank, and most credit unions—allow joint accounts between any two adults. However, some smaller banks and credit unions restrict joint accounts to married couples or registered domestic partners.

If you are in a long-term relationship but not married, call the bank before you visit. Ask directly: "Can two unmarried adults open a joint account?" If the answer is no, you have two options. You can get married, or you can open a regular account in one person's name and add the other person as an authorized user. An authorized user can use a debit card and make withdrawals, but they do not legally own the account—only the primary account holder does.

Some banks also restrict joint accounts if the two people are not related or do not live at the same address. These policies vary widely, so confirm before you apply.

What happens when you add someone to an existing account

If one person already has an account, they can usually add a joint owner without closing and reopening. The process depends on the bank. Some let you do it online or by phone; others require both people to visit a branch together. A few banks let the primary account holder add someone by mail, though this is less common.

When you add someone, the bank will ask for their ID and proof of address, just as if you were opening a new account together. The new joint owner will get their own debit card and online access. All previous transactions stay on the account—the new owner can see the full history.

One important detail: adding someone to an existing account does not automatically change the account type. If it was set up as tenancy in common, it stays that way. If you want to change it to rights of survivorship (or vice versa), you usually have to close the account and open a new one, or sign a new account agreement. Ask the bank what paperwork is needed.

Situations where a joint account does not work

A joint account assumes equal ownership and equal access. If you need something different, a joint account will not do it. Here are common scenarios where people think they need a joint account but actually need something else:

You want to give someone limited access. If you want one person to withdraw money but not deposit it, or to see the balance but not make transfers, a joint account will not work—both owners have full rights. Instead, you can make someone an authorized user on your account (they get a debit card but no ownership), or you can set up a power of attorney that specifies what the other person can do.

You want to keep your money separate but share some expenses. A joint account means all money is legally shared. If you want to keep your paycheck separate but pool money for rent, open a separate account together just for shared expenses, and each person deposits their share into it.

You are managing money for someone else—a parent, a child, or a dependent. A joint account is not the right tool. If you are a parent managing a minor's money, you can open a custodial account in the child's name with yourself as custodian. If you are managing an adult's money because they cannot, you need power of attorney or guardianship, which gives you legal authority without making you a co-owner.

You are worried about creditors or lawsuits. A joint account does not protect money from creditors. If one owner is sued or owes taxes, creditors can seize the joint account, even if the other owner deposited all the money. A joint account actually increases risk for the person with clean finances.

What to bring and what to expect at the bank

If you are opening a joint account in person, both account holders should go together. Bring:

  • A valid government-issued photo ID for each person (driver's license, passport, or state ID)
  • Proof of address for each person (utility bill, lease, mortgage statement, or recent bank statement dated within the last 60 days)
  • Social Security number or tax ID for each person (the bank will ask for this verbally; you do not need to bring a card)
  • Initial deposit (the minimum varies by bank and account type, from $0 to $500 or more)

The bank will ask you to choose an account type (checking, savings, or money market), decide on the ownership structure (usually rights of survivorship unless you request otherwise), and sign account agreements. The whole process usually takes 20 to 30 minutes. You will get debit cards on the spot or within a few business days, and online access is usually available immediately.

If one person is opening the account and adding the other later, the process is simpler. The primary account holder can often do this online or by phone, though the bank may mail forms for the second person to sign.

Frequently Asked Questions

Can I open a joint account if one of us has bad credit?

Yes. Banks do not check credit scores for deposit accounts. They check ChexSystems, which tracks overdrafts, fraud, and unpaid fees at other banks. If either person has a ChexSystems flag, some banks will deny the account, but many will not. Call ahead and ask.

What if one person wants to close the joint account without the other's permission?

Either owner can close a joint account unilaterally. The bank will distribute the balance according to the account agreement—usually split equally, though you can request a different split when you open it. If you are worried about this, a joint account is not safe; consider a separate shared account instead, or a power of attorney with specific limits.

Does opening a joint account affect my credit score?

No. Deposit accounts do not appear on credit reports. However, if the account goes negative and is sent to collections, that can hurt your credit. Both owners are responsible for overdrafts.

Can I open a joint account online, or do we both have to go to the bank?

It depends on the bank. Some allow fully online opening; others require at least one person to visit a branch or verify identity through video call. Call your bank or check their website to see what they require.

What if one owner dies—does the other person automatically get the money?

Yes, if the account is set up as joint tenancy with rights of survivorship, which is the default at most banks. The surviving owner owns the full balance immediately, without probate. If the account is tenancy in common, the deceased owner's share goes to their estate instead. Confirm which type you have when you open the account.
