Yes, you can open a joint account with your son at almost any bank
You and your son can open a joint bank account together at any bank or credit union that offers them. Both of you will own the account equally, both names go on the paperwork, and either of you can deposit or withdraw money without asking permission. The account works the same way whether your son is 18 or 45 — the bank does not care about the age difference or family relationship.
What matters to the bank is that both of you show up with valid identification, provide Social Security numbers, and sign the account agreement. Some banks let you start the process online, but most require at least one in-person visit to verify who you are. A few banks will let one person open the account and add the other person later, but it is simpler to do it together from the start.
The main thing to understand before you open the account is what joint ownership actually means: the money in the account belongs to both of you equally, and either of you can take it all out without telling the other. If you want to set limits on what your son can do, or keep some money separate, a joint account is not the right tool.
Key Takeaways
- Both you and your son must be present with valid ID and a Social Security number to open a joint account at a bank or credit union.
- Either account owner can withdraw all the money or close the account without the other person's permission.
- Joint accounts pass directly to the surviving owner if one person dies, without going through probate or a will.
- If your son has debt or legal judgments against him, creditors may be able to freeze or seize money in a joint account.
- Some banks charge monthly fees for joint accounts, while others offer them free; compare options before you choose.
What you need to bring to the bank
Both you and your son need to bring a government-issued photo ID — a driver's license, passport, or state ID card. The bank will scan or photocopy it. You will also need to provide your Social Security numbers; the bank uses these to run a background check and report the account to the IRS.
Bring a small amount of money to open the account — usually $25 to $100, depending on the bank. Some banks waive this minimum if you set up direct deposit. If you already have an account at the bank, opening a joint account may be faster because they already have your information on file.
If your son lives far away, ask the bank whether he can open the account by video call or mail. Some larger banks offer this option, but many smaller banks and credit unions require both of you to be there in person. Call ahead rather than showing up and finding out the bank cannot help you that day.
How the account is titled and what that means
The bank will ask how you want the account titled. The standard option is joint tenants with rights of survivorship, which means the account belongs to both of you equally and passes to the survivor if one of you dies. This is the most common choice for family accounts.
The other option, available at some banks, is tenants in common. With this setup, each person owns a specific percentage of the account (usually 50/50), and if one person dies, their share goes to their estate rather than automatically to the other person. This is less common for parent-child accounts but matters if you want your share to go to someone other than your son.
Ask the bank which option they recommend and what the difference means for your situation. The bank employee can explain how it affects what happens if one of you dies or if there is a legal claim against the account.
What happens if your son has debt or legal problems
If your son owes money to a creditor, has a court judgment against him, or owes back taxes, that creditor may be able to freeze or take money from the joint account. The creditor does not need your permission — they can go after the account because your son's name is on it. This is one of the biggest risks of opening a joint account.
The same applies if your son faces a lawsuit or has unpaid child support. Once a creditor gets a judgment, they can place a levy on any account with your son's name on it. Your own money in the account is not protected just because you put it there.
If this is a concern, talk to the bank about whether they offer any protections or whether you should consider a different account structure. Some people in this situation choose to keep their own separate account and only use the joint account for money they are comfortable losing.
Fees and account features to compare
Joint accounts are not all the same. Some banks charge a monthly maintenance fee ($5 to $15) for joint accounts, while others offer them free. Some waive the fee if you keep a minimum balance or set up direct deposit. Check the fee schedule before you open the account.
Look at what comes with the account: debit cards for both of you, online banking, mobile app access, overdraft protection, and ATM access. If you plan to use the account mainly for transfers between the two of you, you may not need all these features. If you plan to use it as your main checking account, make sure it has the tools you actually use.
Compare at least two or three banks or credit unions. Credit unions often have lower fees than large banks, but they may have fewer ATMs or branches. A large bank may have more convenient access but charge more. The difference over a year can be $50 to $100 or more.
When a joint account makes sense and when it does not
A joint account works well if you and your son want to share money for a specific purpose — paying household bills together, saving for a family goal, or managing finances if one of you becomes unable to handle banking. It is straightforward and requires no legal paperwork beyond the account agreement.
A joint account does not work well if you want to keep your money separate but give your son access to some of it. If you want to leave money to your son in your will but keep control of it while you are alive, a joint account is not the right tool — it overrides your will. If your son has creditors or legal problems, a joint account puts your money at risk.
If you want your son to have access to your account in an emergency but do not want him to own it, ask the bank about power of attorney instead. With power of attorney, your son can manage the account on your behalf without owning it, and the money stays in your name only.
What happens to the account if one of you dies
If you set up the account as joint tenants with rights of survivorship, the account passes directly to your son when you die. He becomes the sole owner automatically — no probate, no waiting, no court involvement. He can keep using it or close it whenever he wants.
This is actually one of the main reasons people open joint accounts with family members. It avoids probate and gets money to the surviving person quickly. But it also means the money does not go through your will or estate, so it does not count toward paying debts or taxes you owe at death.
If your son dies first, the account becomes yours alone. You keep all the money in it. Make sure you understand this before you open the account, especially if you have other children or specific plans for what should happen to the money.
Frequently Asked Questions
Can I open a joint account with my son if he is under 18?
Most banks require both account owners to be at least 18 years old. If your son is younger, you can open an account in your name only and add him as an authorized user, but he will not own the account — you will. Once he turns 18, you can convert it to a true joint account if you both want to.
Will opening a joint account affect my son's credit score?
No. A joint bank account does not show up on credit reports and does not affect either person's credit score. Credit scores are based on borrowing and repayment history, not on bank accounts. The bank may check your credit when you open the account, but that is a different thing.
Can I remove my son from the account later if I change my mind?
Yes. You can go to the bank and ask to remove him from the account or convert it to an account in your name only. Your son does not have to agree — you can do this on your own. However, if there is money in the account, the bank may require both of you to be present to decide what happens to it.
What if my son and I disagree about how to use the money in the account?
The account agreement gives both of you equal rights, so either of you can withdraw money without the other's permission. If you are worried about disagreements, a joint account may not be the right choice. Consider keeping separate accounts or using a power of attorney arrangement instead.
Do I need a lawyer to open a joint account?
No. Opening a joint account is a straightforward banking transaction that requires no lawyer. The bank provides the account agreement, you both sign it, and you are done. A lawyer is only necessary if you want to set up something more complex, like a trust or power of attorney.
