A safe deposit box is a locked metal container inside a bank's vault that you rent to store important documents and valuables
A safe deposit box is a small, secure compartment—usually about the size of a shoebox or smaller—that sits in your bank's vault. You rent it from the bank, keep the only key (or one of two keys), and use it to store things you want to protect from theft, fire, or loss. The bank does not open it, does not know what is inside, and does not have access to it without a court order.
The box itself belongs to the bank. You are paying for the right to use it and for the bank's security measures—the vault, the alarm system, the restricted access. When you rent one, you sign a contract that spells out what you can and cannot store, how long you can keep it, and what happens to the contents if you stop paying or die.
Key Takeaways
- Safe deposit boxes cost between $25 and $200 per year depending on the box size and your bank, and you pay this rental fee whether you use the box or not.
- You can store documents like wills, deeds, birth certificates, and insurance policies, but most banks prohibit cash, firearms, and items of illegal origin.
- Only you and anyone you name on the contract can access the box during business hours; the bank cannot open it without a court order.
- If you die, the box may be sealed by the state, and your heirs will need a court order or to work with an executor to access the contents.
What you can and cannot store in a safe deposit box
Banks have rules about what goes inside. You can store original documents—wills, property deeds, marriage certificates, divorce decrees, adoption papers, titles to vehicles or boats. You can store insurance policies, stock certificates, bonds, jewelry, coins, photographs, and heirlooms. You can store a list of your passwords or account numbers, though some people prefer to keep this information elsewhere.
Most banks prohibit large amounts of cash, firearms and ammunition, illegal drugs, and anything that is stolen or obtained illegally. Some banks do not allow perishable items, living things, or anything that could damage the box or other boxes nearby. A few banks prohibit items with sentimental value only (like old letters), though this is less common. When you rent a box, the bank gives you a contract that lists what is forbidden—read it before you sign.
The bank is not responsible for what happens to your contents. If the vault floods, if there is a fire, or if someone breaks in, the bank's liability is usually limited to the rental fee you paid. This is why a safe deposit box is not the same as insurance. If you are storing something valuable, you may want to insure it separately through your homeowner's or renter's policy.
How much safe deposit boxes cost
The annual rental fee varies by bank and by box size. A small box might cost $25 to $50 per year. A medium box might cost $75 to $125. A large box might cost $150 to $200 or more. Some banks charge less if you maintain a certain account balance or have a checking account with them. A few banks offer a small box free to customers who meet certain requirements, though this is rare.
You pay the fee once a year, usually in advance. If you close your account or stop renting the box, you may be charged a prorated fee for the months you used it. If you do not pay the rental fee, the bank will eventually drill open the box and remove your contents, storing them (usually at your expense) until you pay or until the state takes them.
How to access your safe deposit box
When you rent a box, you receive a key. The bank keeps a second key in a secure location. To open your box, you go to the bank during business hours, show your ID, and sign a log. A bank employee escorts you to the vault, uses their key and your key together to open the box, and then leaves you alone in a private room to add, remove, or view your contents. You then return the box to the vault, and the employee locks it again.
You cannot access the box after hours, on weekends, or on bank holidays. If you lose your key, the bank can make a replacement, usually for a fee of $25 to $100. If you lose both keys, the bank will drill the box open, which is expensive and may damage the contents.
Anyone you name on the contract—a spouse, an adult child, a business partner—can access the box the same way, without your permission and without telling you. This is why you should only add someone you trust completely. If you want to remove someone's access, you must contact the bank and update the contract.
What happens to your safe deposit box when you die
When a bank learns that a box holder has died, the box is usually sealed. The state may require the bank to inventory the contents for tax purposes. Your heirs cannot simply open the box and take what is inside. Instead, the person named as executor in your will (or a court-appointed administrator if there is no will) must go to the bank with a death certificate and a court document proving they have the authority to manage your estate. The executor can then access the box and remove the contents.
This process can take weeks or months, depending on how busy the probate court is. If you have a will inside the box, the executor needs to get it out quickly so it can be filed with the court. Some states allow the executor to access the box for this purpose before the full probate process begins. If you have named someone as a co-renter on the box, that person can usually access it immediately after your death, though they may need to show a death certificate.
If no one claims the box and no one pays the rental fee, the bank will eventually drill it open and turn the contents over to the state's unclaimed property program. Your heirs can then try to recover the items by contacting the state.
Safe deposit boxes versus other storage options
A safe deposit box is not the only way to store important documents. You can keep originals at home in a fireproof safe, though a home safe is vulnerable to theft and may not survive a major fire. You can store digital copies in a password-protected cloud service like Google Drive or Dropbox, which is convenient but requires you to trust the company's security. You can give copies to a trusted family member or attorney, which spreads the risk but means someone else knows what you own.
A safe deposit box is best for documents and items you rarely need to access—wills, deeds, birth certificates, insurance policies, jewelry. It is not ideal for things you need to reach quickly or for cash you might need in an emergency. It is also not a substitute for insurance; if something in the box is damaged or stolen, the bank will not pay you back.
Frequently Asked Questions
Can the bank see what is inside my safe deposit box?
No. The bank cannot open your box without your permission or a court order. They do not know what is inside, and they do not monitor the contents. The only exception is if the bank suspects illegal activity or if a court orders them to open it as part of a legal case.
What should I do if I lose my safe deposit box key?
Contact your bank immediately. They can usually make a replacement key for a fee, or they can drill the box open if you have lost both keys. Bring your ID and the box rental agreement. The process usually takes a few days to a week.
Can I use a safe deposit box to hide money from creditors or taxes?
No. If you are sued or audited, a court can order the bank to open your box and reveal the contents. Hiding assets to avoid paying debts or taxes is illegal and can result in criminal charges.
Is my safe deposit box insured if there is a fire or break-in?
The bank's liability is usually limited to the rental fee you paid, not the value of what is inside. If you are storing something valuable, you should insure it separately through your homeowner's or renter's policy. Check your policy to see what it covers.
Can I rent a safe deposit box if I do not have a bank account?
Most banks require you to have at least a checking or savings account to rent a safe deposit box. Some banks may make exceptions, but this is uncommon. Call your bank to ask about their requirements.
