How to Add Another Signer to Your Checking Account

The basic process: what happens at your bank

To add a signer to your checking account, you visit your bank in person or call them, provide the new signer's information, and both of you sign paperwork authorizing the change. The bank then updates their records, issues a new debit card if needed, and the new signer can use the account when ready. The whole process usually takes a few minutes in a branch or a few days by mail, depending on your bank.

The exact steps vary slightly by bank, but the core requirement is always the same: the bank needs to verify the new signer's identity and get written consent from both you and them. Some banks let you start online, but most require at least one signature on paper.

Key Takeaways

You and the new signer must both be present in person at most banks, or the bank will mail forms for both of you to sign and return.
Bring a government-issued photo ID for the new signer — a driver's license, passport, or state ID card — so the bank can verify who they are.
The new signer becomes a full owner of the account with equal rights to withdraw money, close the account, or change account settings unless you set restrictions.
Some banks charge a small fee to add a signer; others do not, so ask before you start the process.
The new signer will receive their own debit card and online login, usually within one to two weeks.

What documents you need to bring

You will need your account number or debit card, and the new signer will need a government-issued photo ID. A driver's license, passport, or state ID card all work. The bank uses this to confirm the person's legal name, date of birth, and address.

If you are adding a signer by mail because you cannot both visit the branch, the bank will send you blank signature cards or authorization forms. You and the new signer each sign these and mail them back. Some banks also ask for a copy of the new signer's ID, so ask when you request the forms whether you need to include one.

In-person versus by mail: which is faster

Adding a signer in person at a branch is almost always faster. You can walk out the same day with the change recorded in the bank's system, though the new signer's debit card and online access may take a week or two to arrive. By mail, the entire process takes two to four weeks because the bank has to mail you forms, wait for you to sign and return them, and then process the paperwork.

If you live far from a branch or cannot both visit at the same time, call your bank and ask whether they offer remote notarization or video verification. Some larger banks now let you verify the new signer's identity over video call, which speeds up the mail process.

What rights the new signer will have

Once added, the new signer becomes a joint owner of the account. This means they can withdraw money, deposit checks, set up automatic payments, order new debit cards, and change account settings — all without asking your permission. They can also close the account entirely. If you want to limit what they can do, ask your bank whether they offer restricted access or limited power of attorney options, though not all banks provide these.

The new signer's name will appear on the account and on any statements. If you are adding a minor, the account may be set up as a custodial account instead, which gives you more control over what they can withdraw until they reach adulthood — usually 18 or 21, depending on your state.

Adding a minor versus an adult

Adding a minor to your account works differently than adding an adult. Most banks require the minor to be at least 13 or 16 years old, though this varies. The account is usually set up as a custodial account, meaning you retain legal control until the minor reaches the age of majority in your state — typically 18 or 21.

For a minor, you will need to bring both their birth certificate and a government-issued ID if they have one (a school ID or state ID card). Some banks also require a parent or guardian to be present. The minor's access to the account may be limited — for example, they might not be able to close the account or make large withdrawals without your approval — depending on the bank's rules.

Fees and what to ask your bank

Most banks do not charge to add a signer to an existing account, but some do. Call your bank's customer service line or visit a branch and ask directly: "Is there a fee to add a signer to my checking account?" If there is, ask whether it is a one-time fee or an ongoing monthly charge.

While you have them on the phone, also ask whether the new signer will need to set up online banking separately, whether they will receive a debit card automatically, and how long each step takes. Different banks handle these details differently, so getting answers upfront prevents surprises later.

What happens if you change your mind

Removing a signer is usually simpler than adding one. You can typically do it by phone or in person, and the change takes effect within a day or two. The removed signer's debit card will stop working, and they will lose access to online banking for that account.

If the signer is a minor and the account is custodial, removing them may happen automatically when they reach the age of majority, depending on your bank's policy. Ask your bank what happens at that point — whether the account converts to a regular joint account, whether the young adult must open their own account, or whether they have a choice.

Frequently Asked Questions

Can I add a signer without them being present?

Most banks require both signers to be present in person or to sign paperwork by mail. A few banks now offer video verification, which lets you add a signer remotely without mailing forms back and forth. Call your bank and ask whether they have this option.

What if the new signer lives in a different state?

You can still add them. If you cannot both visit a branch, request the mail-in forms from your bank. Both of you sign and return them. Some banks may ask for a copy of the new signer's ID or require notarization, so confirm the requirements when you request the forms.

Will adding a signer affect my credit score?

No. Adding a signer to a checking account does not appear on credit reports and does not affect either person's credit score. Credit reports track borrowing and repayment, not checking account ownership.

Can I add a signer to a savings account instead of a checking account?

Yes. The process is nearly identical — you provide the new signer's information, both of you sign authorization forms, and the bank updates the account. Ask your bank whether they charge differently for savings accounts or whether any restrictions explore.

What if I want to add a signer but keep some money private?

A joint account gives both signers equal access to all the money in it. If you want to keep some funds separate, open a second account in your name only and keep only the shared money in the joint account. This is the clearest way to protect your privacy.
