The Basic Steps to Add Your Spouse
Adding your spouse to your checking account requires you to visit your bank in person or call them to start the process. Most banks will not let you add an account holder over the phone alone — they want to verify identity and get signatures. You will need your spouse's Social Security number, date of birth, and a government-issued ID (driver's license, passport, or state ID card).
The bank will ask whether you want your spouse as a joint owner (both of you own the account equally and can make all decisions) or as an authorized user (they can use the account but you retain legal ownership). This choice matters for taxes, liability, and what happens if one of you dies. Most couples choose joint ownership, but some keep one person as the primary owner for specific reasons — talk to your bank about what fits your situation.
Once the bank has the information and signatures, the change usually takes one to three business days. Your spouse will receive a debit card and online login credentials within a week or two, depending on the bank's mail speed.
Key Takeaways
- You must visit your bank branch in person or call to start adding your spouse; most banks will not complete this online.
- Bring your spouse's Social Security number, date of birth, and government-issued ID to the appointment or have them ready when you call.
- Decide whether your spouse will be a joint owner (equal control) or an authorized user (limited control) before you meet with the bank.
- The account change takes one to three business days, and your spouse's debit card and login access arrive within one to two weeks.
Joint Owner vs. Authorized User — What the Difference Means
A joint owner has equal legal rights to the account. Both of you can withdraw money, close the account, change the account terms, or add other people. If one spouse dies, the surviving spouse automatically owns the full balance (this is called "right of survivorship" and happens at most banks unless you specifically opt out). For taxes, the bank reports interest income to both Social Security numbers.
An authorized user can use the debit card and access the account online, but you (the primary owner) retain all legal control. You can remove them at any time without their permission. If you die, the account does not automatically pass to them — it becomes part of your estate. The bank reports all interest to your Social Security number only.
Most married couples choose joint ownership because it is simpler and avoids probate if one spouse dies. But some people keep one spouse as the primary owner if they have significant debt, are protecting assets from creditors, or want to keep finances separate for other reasons. Ask your bank whether your account is set up with right of survivorship — this is the default at most institutions, but you can change it if you want the account to go through probate instead.
What Information and Documents You Need
Bring or have ready your spouse's full legal name (as it appears on their ID), Social Security number, date of birth, and current address. The bank will also ask for a government-issued photo ID — a driver's license, passport, or state ID card. Some banks accept military IDs or tribal IDs as well.
If your spouse does not have a Social Security number (for example, if they are a non-citizen), ask your bank whether they can use an Individual Taxpayer Identification Number (ITIN) instead. Not all banks accept ITINs, so call ahead to confirm. A few banks have special accounts for people without SSNs, but these are less common.
You will also need to sign paperwork authorizing the change. If you are adding your spouse in person, you both sign at the branch. If you are doing this by phone or mail, the bank will send signature cards for both of you to sign and return.
How Long the Process Takes and When Your Spouse Can Use the Account
The bank updates the account ownership in one to three business days. During this time, your spouse cannot yet use the account — the system has to process the change and issue new credentials. Once the ownership change is complete, your spouse can access the account online immediately if they set up their login at the branch or by phone.
The physical debit card arrives by mail within five to ten business days at most banks, though some take up to two weeks. Your spouse can use the account online and through mobile banking before the card arrives. If they need a card urgently, ask whether the bank can issue a temporary card at the branch or expedite shipping for a fee.
Checks linked to the account may take longer to arrive if your spouse requests new checks with their name on them. Most banks can print checks within three to five business days if you order at the branch, or seven to ten days if you order online.
What Happens to Existing Balances and Account Features
Adding your spouse does not change your account balance, interest rate, or monthly fees. The account keeps the same account number and routing number. Any automatic payments, direct deposits, or transfers you have set up continue without interruption.
Your spouse will have full access to the existing balance once they are added as a joint owner. If they are an authorized user, they can see the balance and make withdrawals, but you retain the legal right to remove them or change the account terms.
If your account has overdraft protection or a linked savings account, your spouse will have access to those features too. Ask your bank to explain any overdraft fees or limits — some banks charge overdraft fees per transaction, and you want both of you to understand the cost if the account goes negative.
Adding Your Spouse if You Bank Online or at a Credit Union
Online banks (like Ally, Charles Schwab, or Discover) usually require you to start the process by phone or through their app, then mail in signature cards. Call the bank's customer service line and ask for the steps to add a joint owner. They will mail you and your spouse signature cards to sign and return. Once the bank receives the signed cards, the change takes one to three business days.
Credit unions follow the same basic process as traditional banks — you visit a branch or call to start. If your credit union is part of a shared branching network (most are), you can also visit another credit union branch to add your spouse, though you may need to call your home branch first to confirm they can process it.
If you use an online bank and do not have a local branch, ask whether they offer video verification or whether they will accept notarized signature cards. Some online banks have started offering these options, but policies vary widely.
Frequently Asked Questions
Can I add my spouse without them being present?
Most banks require your spouse to sign paperwork, but not necessarily in person. You can call the bank, provide their information, and ask them to mail signature cards to both of you. Once you both sign and return the cards, the bank processes the change. Some banks offer video verification where your spouse can sign on camera instead of mailing documents.
Will adding my spouse affect my credit score?
Adding your spouse as a joint owner does not affect either of your credit scores. The bank does not run a credit check for this change. However, if your spouse becomes an authorized user on a credit card account (different from a checking account), that may appear on their credit report depending on the card issuer's policy.
What if my spouse has a different last name?
That does not matter. The bank uses your spouse's legal name as it appears on their government ID and Social Security card. If they have not legally changed their name, use the name on their ID. If they want to change their name on the account later, they can do that through a separate legal name-change process.
Can I remove my spouse from the account later?
Yes, but the process depends on whether they are a joint owner or authorized user. If they are an authorized user, you can remove them by calling the bank or visiting a branch — they do not have to agree. If they are a joint owner, most banks require both of you to sign a form to remove one person. Some banks allow one joint owner to remove the other unilaterally; call your bank to ask about their specific policy.
What happens to the account if my spouse dies?
If your spouse is a joint owner with right of survivorship (the standard setup), you automatically own the full account balance. The bank will remove their name from the account, and you keep using it. If your account does not have right of survivorship, the balance becomes part of their estate and goes through probate. Ask your bank to confirm your account has right of survivorship when you add your spouse.
