You can add a joint owner to a Chase checking account in person at a branch, by phone, or through Chase's online banking portal — but the person you're adding must be present or provide written consent, and both of you will need valid ID.
Chase does not allow you to add someone as a joint owner remotely without their involvement. The account holder and the person being added must either visit a branch together, or the new owner must sign a consent form that Chase provides. Once added, both owners have equal access to the account, can withdraw funds, and are responsible for overdrafts or fees.
The fastest route is usually a branch visit with both people present and two forms of ID each. Phone and mail options exist but take longer because Chase needs written authorization from the person being added.
Key Takeaways
- Both the current account holder and the person being added must provide valid ID and consent — Chase will not add someone without their knowledge or signature.
- A branch visit with both people present is the quickest method and can be completed in one appointment.
- If the new owner cannot visit a branch, Chase can mail a consent form for them to sign and return.
- Once someone is added as a joint owner, they have full access to the account and equal responsibility for all activity and fees.
- You cannot convert an existing account to joint ownership online; you must contact Chase directly by phone or in person.
Adding a joint owner in person at a Chase branch
Bring your checking account number, your ID, and the ID of the person you want to add. Both of you should visit the branch together. Tell the teller or banker you want to add a joint owner to your account. They will verify both identities, confirm that the new owner consents, and update the account on the spot.
The branch will provide a form for the new owner to sign. This usually takes 10 to 15 minutes. Once signed, the account is converted to joint ownership immediately, and both owners can use the debit card and online access right away. If the new owner does not yet have a Chase online banking login, the branch can set that up during the same visit.
Adding a joint owner by mail when they cannot visit a branch
Call Chase at the number on the back of your debit card and tell them you want to add a joint owner. Provide the new owner's full name, date of birth, and Social Security number. Chase will mail a consent form to the address on file for your account.
The new owner must sign the form in front of a notary public or witness (depending on what Chase requires — ask when you call). Mail the signed form back to Chase in the prepaid envelope they provide. Processing takes 5 to 10 business days after Chase receives the completed form. You will receive written confirmation when the account has been converted to joint ownership.
What happens to the account once someone is added as a joint owner
A joint owner has the same rights and responsibilities as the original account holder. Both owners can deposit money, withdraw funds, pay bills, set up transfers, and view the full transaction history. Both names appear on the account and on any debit cards issued.
Both owners are equally liable for overdraft fees, insufficient funds charges, and any other account fees. If one owner overdraws the account, the other owner is responsible for the negative balance. If one owner closes the account or disputes a transaction, it affects both owners. There is no way to restrict one owner's access to certain funds or transactions once they are added.
ID and documentation you need to bring
Both the current account holder and the person being added must bring two forms of valid ID. Acceptable forms include a driver's license, passport, state ID card, or military ID. Chase will not accept expired IDs or documents like Social Security cards or birth certificates as a primary form of identification.
Have your checking account number ready. If you are adding someone who is not yet a Chase customer, they do not need an existing account — Chase will create one as part of the joint ownership process. If they already bank with Chase, bring their account number as well so Chase can link the accounts if needed.
Removing a joint owner later
If you need to remove a joint owner in the future, you must visit a Chase branch in person or call Chase. The account will be converted back to single ownership under the original account holder's name. Any funds in the account remain accessible to both owners until the change is processed, so coordinate with the other owner beforehand if there are funds to divide.
Chase typically processes removal requests within 1 to 3 business days. Once removed, the other person loses access to the account, online banking, and any debit card linked to it. The account history remains available to the original owner.
What to do if the other person is unavailable or unwilling
Chase requires the consent of the person being added. If they are out of state, out of the country, or simply unavailable, you can request that Chase mail a consent form. If they are unwilling to sign, Chase will not add them to the account.
If you need someone to have access to your account but do not want to make them a joint owner, ask Chase about a power of attorney or authorized user option. These alternatives give limited access without converting the account to joint ownership. The rules and availability of these options vary, so call Chase to discuss what works for your situation.
Frequently Asked Questions
Can I add a joint owner to my account without them being present?
No. Chase requires the new owner to sign a consent form either in person at a branch or by mail with a notary signature. They cannot be added without their knowledge or written permission.
Does adding a joint owner affect my credit score?
No. Adding a joint owner to a checking account does not appear on credit reports or affect either person's credit score. Credit inquiries only happen when someone applies for credit, not when opening or modifying a deposit account.
Can I add a joint owner if they don't have a Social Security number?
Chase requires a Social Security number or Individual Taxpayer Identification Number (ITIN) to add someone as a joint owner. If the person does not have one, they will need to obtain an ITIN from the IRS before Chase can complete the process.
What if I want to add a minor as a joint owner?
Chase allows minors to be added as joint owners, but a parent or legal guardian must be present and provide consent. The minor must also have a valid ID, such as a school ID or passport. Some Chase branches may have additional requirements for accounts with minors, so call ahead to confirm.
How long does it take to add a joint owner?
In person at a branch, it takes 10 to 15 minutes. By mail, it takes 5 to 10 business days after Chase receives the signed consent form. Phone requests require a mailed form, so the timeline is the same as the mail option.
