The basic process depends on your bank and the type of account access you want
Adding someone to your checking account means giving them legal rights to the money in it. Most banks let you do this in person at a branch, online through your account dashboard, or over the phone. The person you're adding will need to provide identification and sign paperwork — some banks require them to be present, others don't. The whole process usually takes a few minutes to a few days, depending on whether you do it in branch or remotely.
Before you start, decide what kind of access you want to give. A joint account holder has full rights to deposit, withdraw, and manage the account — they can close it or remove you. An authorized user (sometimes called a signer) can use a debit card and write checks but may have fewer rights to change account settings. Not every bank offers both options, so check what your bank calls these roles.
Key Takeaways
- Joint account holders have equal legal rights to all the money; authorized users typically can spend but not change account settings.
- You will need the other person's Social Security number, date of birth, and current address, plus a government ID they can show the bank.
- In-branch additions usually take minutes; remote additions can take several business days while the bank verifies information.
- Both of you are responsible for overdrafts and account fees, and either of you can close the account without the other's permission.
Adding someone in person at your bank branch
Go to any branch of your bank with the person you want to add. Bring your ID and theirs — a driver's license, passport, or state ID card. Tell the teller you want to add them to your account and ask whether they'll be a joint owner or authorized user.
The bank will ask for the other person's Social Security number, date of birth, and current address. They'll verify the ID and run a background check (this is standard and doesn't mean anything is wrong). You'll both sign paperwork — usually a signature card or account agreement. The bank may ask security questions to confirm your identity. Once everything is signed, the change takes effect immediately or within one business day, and you'll both get new debit cards if the account has them.
Adding someone online or by phone
Log into your bank's website or app and look for "Account Settings," "Manage Account," or "Add Authorized User." You'll enter the person's name, Social Security number, date of birth, and address. Some banks ask you to upload a photo of their ID. You may be able to complete this alone, or the bank may require the other person to verify their identity separately — they might get a text or email with a link to confirm.
Remote additions take longer than in-branch ones. Expect three to five business days while the bank verifies information and processes the request. Some banks send a new debit card by mail, which adds another week. If you need the person to have access faster, going to a branch in person is quicker.
What happens after someone is added
Once the person is added, they can use the debit card, write checks, and access the account online or through the app using their own login. They'll see all transactions and the full balance. If the account is set up for overdraft protection, they can overdraw it, and you're both liable for the fee.
Either of you can deposit money, withdraw money, or transfer funds out. Either of you can also close the account without asking the other person's permission — this is a real risk if you're adding someone you don't fully trust. Some banks let you set daily withdrawal limits or spending caps for authorized users, but not for joint owners. Check your bank's rules on what restrictions are available.
Information you'll need to provide
| Information needed | Who provides it | Why the bank needs it |
|---|---|---|
| Social Security number | The person being added | Tax reporting and identity verification |
| Date of birth | The person being added | Age verification and identity confirmation |
| Current address | The person being added | Mailing address for statements and cards |
| Government-issued ID | The person being added | Photo verification that the person is who they claim to be |
| Your account number | You | Identifies which account is being modified |
Differences between joint owners and authorized users
A joint owner has equal legal claim to the money. If you die, the account passes to them automatically — it doesn't go through your will. They can close the account, change the account type, remove you, or add other people. They're liable for overdrafts and fees just like you are. If you're married or in a long-term partnership and want to share finances, joint ownership is standard.
An authorized user can spend the money but has fewer legal rights. They can't usually close the account or change settings without your permission. If you die, the account may freeze or go to your estate instead of passing to them automatically — this varies by bank. Authorized users are still liable for overdrafts. This option works well if you want to give a teenager or caregiver access to spend but not full control.
Not all banks offer both options. Some only offer joint accounts. Call your bank or check their website to see what they support.
What to do if you need to remove someone later
Removing a joint owner is harder than removing an authorized user. To remove a joint owner, most banks require both of you to agree and sign paperwork in person. Some banks let you remove them online if you're the account holder who opened it, but this varies. If the other person won't cooperate, you may have to close the account and open a new one.
Removing an authorized user is simpler — usually you can do it online or by calling the bank. The person being removed loses access to the debit card and online login immediately, though the bank may take a business day to process it. If you're concerned about someone misusing the account, remove them right away and consider changing your online password.
Frequently Asked Questions
Can I add someone to my account without them being present?
Yes, many banks allow remote additions where you provide their information and they verify themselves separately by email or text. Some banks still require both people to be present in a branch. Call your bank to ask what they require — it depends on their policy and whether you're adding a joint owner or authorized user.
Will adding someone affect my credit score?
No. Adding someone to a checking account doesn't show up on credit reports and doesn't change your credit score. Credit reports track credit accounts like loans and credit cards, not checking accounts. The bank will do a background check, but that's internal verification, not a credit inquiry.
What if the person I want to add doesn't have a Social Security number?
Banks require a Social Security number or Individual Taxpayer Identification Number (ITIN) for tax reporting. If the person doesn't have one, they'll need to get an ITIN from the IRS first. Some banks may have exceptions for non-citizens, so ask your bank directly about their policy.
Can I add someone to just part of my account balance?
No. When you add someone to a checking account, they get access to the entire balance and all transactions. You can't split the account or restrict them to a portion of the money. If you want to give someone access to only some of your money, you'd need to open a separate account and transfer that amount into it.
What happens to the account if the other person dies?
If you're a joint owner, the account passes to you automatically. If you're an authorized user, the account may freeze or go to the deceased person's estate — this depends on your bank's rules and state law. Contact your bank to find out what will happen in your situation.
