Abandoned Safe Deposit Boxes: Notice, Drilling, Inventory and Remittance

9/23/2026

Drilling a safe deposit box is one of the few routine bank operations that destroys property and exposes sealed contents in the customer's absence. Everything about the process is designed around one question that may be asked years later: can the bank prove what was in the box, that it had the right to open it, and that every item went where the law required?

Safe deposit box laws are almost entirely state law. There is no federal statute that tells a bank when it may drill a box or how long it must hold the contents. What is consistent across states is the shape of the process: a trigger, notice, a waiting period, a witnessed opening and inventory, safekeeping, and eventually remittance of unclaimed contents to the state under its unclaimed property law. This post walks through that sequence, flags where states differ, and covers the documentation that protects the bank.

Two Different Triggers

Banks reach a drilled box by two routes that are easy to confuse and should not share a single workflow.

Unpaid rent or lease termination. The renter stopped paying, or the lease ended and the box was not vacated. This is a contractual default under the rental agreement, overlaid by the state's banking or safe deposit statute, which usually sets the notice and waiting requirements before the bank may open the box. New York, for example, provides special remedies in Section 335 of its Banking Law for boxes whose rent is not paid or that are not vacated at the end of the lease.

Abandonment under unclaimed property law. The contents are presumed abandoned because the owner has not claimed them for the statutory period. Under the Revised Uniform Unclaimed Property Act, the 2016 model act from the Uniform Law Commission, tangible property in a safe deposit box is presumed abandoned if it remains unclaimed five years after the earlier of the expiration of the lease or rental period, or the earliest date the bank is authorized by other state law to enter the box and remove the contents. States set their own periods, and they vary.

In practice, the two often run in sequence: unpaid rent leads to a drilling under the banking statute, and the contents removed then sit in the bank's safekeeping until the unclaimed property period runs and they are reported. But a box can be paid up through auto-debit from an account the owner abandoned long ago, and a box can go unpaid while the owner is very much alive and reachable. Treat each trigger on its own facts.

When the estate process governs instead

If the bank has notice that the renter has died, the estate process, not the abandonment process, governs access to the box. State law decides who may open it, whether a limited opening to look for a will or burial instructions is permitted, and what inventory is required. Check for a death notice before starting any drilling workflow. Our post on estate settlement and the trust department's role covers the estate side.

Before Drilling: Notice

Notice is the bank's legal foundation for opening the box. The common elements, each set by state law and the rental agreement, are:

  • Confirm the trigger and the date it occurred, and verify the agreement terms.
  • Confirm no death notice or legal process is on file.
  • Send notice to the renter at the address of record by the method the statute requires, which may be certified or registered mail.
  • Send further notice if the state requires more than one attempt.
  • Publish notice if the state requires publication.
  • Let the full waiting period run before acting.
  • Keep proof of every notice: copies, mailing receipts, return receipts and returned envelopes.

The most frequent defect is a notice sent to an address the bank knew was stale. If a better address is on file for the same customer's deposit or loan relationship, use it. A notice that could not reach the renter does little to protect a bank that had a better address all along.

At Drilling: Two People and a Contemporaneous Inventory

The opening itself is where most later disputes are won or lost. Bank policy and many state statutes require witnesses. The standard practice is:

  • At least two bank employees present throughout, plus any additional witness, such as a notary, that the state statute or bank policy calls for.
  • Drilling by a qualified locksmith or approved method, with the locksmith's details recorded.
  • An item-by-item inventory made at the moment of opening, in the presence of the witnesses, describing each item without valuing it unless policy requires an estimate.
  • Signatures of every witness on the inventory.
  • Photographs or video where bank policy allows.
  • Sealing the contents in a numbered envelope or container, with the seal number recorded on the inventory.
  • Recording costs: drilling, lock replacement and unpaid rent, which the bank may later recover.

Describe items neutrally. Write "yellow metal ring with clear stone," not "gold diamond ring." An inventory that overstates value creates a claim when the item is returned, and one that is vague creates a claim that something is missing.

The NAUPA III reporting format published by the National Association of Unclaimed Property Administrators reflects what states expect the bank to know at reporting time: the box number, the date the box was drilled, the lease expiration date, drilling and unpaid rent fees, and an inventory of items with category codes such as coins or bullion, paper currency, jewelry, legal or miscellaneous papers, military medals, savings bonds and "empty box." Building your inventory form around those categories saves work when you report.

After Drilling: Safekeeping and Owner Contact

Once the box is opened, the contents are held in dual-control safekeeping. During that period:

  • Try to reach the owner again, with the inventory available, using every address the bank has.
  • Hold the contents for the statutory safekeeping period before reporting.
  • Log every access to the safekeeping container.
  • Release contents only to the renter or a person legally entitled, after identification and on a signed receipt against the inventory.

If the renter reappears, the bank's drilling and rent charges are typically collected before release under the rental agreement and state law.

Remittance: How Safe Deposit Box Contents Escheat

When the unclaimed property period runs, the contents are reported and delivered to the state under its unclaimed property law, usually on the state's annual reporting cycle and its specific instructions for tangible property. Several rules commonly apply.

Not every item goes the same way

Contents are a mix of cash, valuables, documents and intangible property, and states treat them differently. New York's reference sheet for banking institutions illustrates the range:

  • Cash, including net proceeds of any auction, and securities are reported three years from the date the box was opened.
  • Banks are not required to hold an auction, but if they do, net proceeds are reported box by box after subtracting the auctioneer's expenses and reasonable bank fees.
  • Papers and property of no apparent value must be retained for at least ten years under New York's Banking Law.
  • Checks found in a box are not reported; the issuer reports the underlying funds.
  • Coins with market value above face value, including U.S. silver dollars, are not reported or offset against fees; the bank retains and auctions them.
  • Series E, EE and I savings bonds are not reported to the state; the bank retains them or forwards them with a letter to Treasury Retail Securities Service.
  • Security certificates need value and transferability checked, and the bank must contact the state before sending any.

Other states take different positions on auctions, documents, savings bonds and coins. The 2016 model act notes that intangible property evidenced by a document in the box, such as a stock certificate or certificate of deposit, is governed by the general rules for that property, not by the safe deposit box section.

Reimbursement of the bank's costs

The 2016 model act gives the bank a right to reimbursement for the cost of opening the box and for unpaid rent under a lien or contract, paid by the state from the proceeds remaining after the state deducts its own expense of selling the property. States differ on whether the bank deducts costs before delivery, files them with the report or claims them afterward. The report itself, under the model act, must indicate where the property is held, where the state can inspect it, and any amounts owed to the bank.

Reporting codes

Safe deposit box contents are reported under NAUPA property code SD01 in the NAUPA II format and SD001 in NAUPA III, with other safekeeping under SD02 and SD002. NAUPA III also has a code for proceeds from the sale of tangible property before reporting.

Safe Deposit Rules and Regulations Inside the Bank

Beyond the statute, a bank's own rules for safe deposit boxes should cover:

  • The rental agreement: rent, default, the bank's right to drill and the notice it will give, liability limits where the state permits them, and the statement that contents are not FDIC insured. Deposit insurance covers deposits, and a box is a lease of space, not a deposit. Our post on FDIC insurance coverage explains the line.
  • Access controls: dual control, identification at every access and a signed access log.
  • A written drilling procedure for each state where the bank rents boxes, with the notice method, waiting period, witness requirements and safekeeping period sourced from the current statute.
  • A safekeeping inventory system that tracks each container from drilling to release or remittance.
  • Escalation for unusual contents: firearms, hazardous material, large amounts of cash or anything suggesting criminal activity. These go to security and, where required, to law enforcement, and cash found in unusual circumstances may raise BSA questions for the compliance team.

The operational side of boxes, from rental to co-renters and access, is covered in our post on safe deposit box operations, and the safe deposit box training page collects related courses.

Why No Table of State Periods

Waiting periods, notice methods, publication rules, safekeeping periods and remittance rules differ more for safe deposit boxes than for deposit accounts, and legislatures change them. A wrong period on this process does not produce a reporting error. It produces a destroyed lock and an opened box with no legal basis. Confirm each requirement against your own state's banking statute and unclaimed property administrator before drilling, every time the procedure is updated.

Training the People Who Open Boxes

Safe deposit box work is usually handled by branch operations staff who do it rarely, which is exactly why it goes wrong. Clear procedures and periodic training keep the process defensible. Deposit Accounts and Services covers the deposit products and services that branch and operations staff support, and the bank operations page lists related operations courses.

Next Step

Pull your most recent drilled-box file and check it against this sequence: proof of notice to the best address, the waiting period, two witness signatures on a contemporaneous inventory, sealed safekeeping with an access log, and a remittance that followed the state's rules for each type of item. For branch and operations staff who handle boxes alongside deposit work, Deposit Accounts and Services is a practical starting point.

Frequently Asked Questions

What happens to an abandoned safe deposit box?

After the renter stops paying rent or the lease ends, the bank sends the notices state law requires and waits the required period. It then drills the box in front of witnesses, inventories the contents and holds them in safekeeping. If the owner still does not come forward, the contents are reported and delivered to the state as unclaimed property. The state may sell valuables and hold the proceeds for the owner, who can file a claim.

How long before a safe deposit box is considered abandoned?

It depends on the state. The 2016 model act presumes box contents abandoned five years after the earlier of the lease expiration or the date the bank is legally allowed to open the box, but states set their own periods. Separately, state banking law sets how long rent can go unpaid, and what notice is required, before the bank may drill. Check both statutes for each state where you rent boxes.

Can a bank drill a safe deposit box without permission?

Yes, in defined circumstances such as unpaid rent, termination of the lease or a court order, but only after following the notice and waiting requirements in the rental agreement and state law. Drilling without meeting those requirements exposes the bank to claims. If the renter has died, the estate process governs access instead. Banks should also confirm no legal process or death notice is on file before drilling.

Who must be present when a safe deposit box is drilled?

State law and bank policy set the requirement, and the standard practice is at least two bank employees present throughout, with a locksmith performing the drilling. Some statutes or bank policies add a notary or other designated witness. Every witness signs the inventory made at the moment of opening, and the contents are sealed and placed in dual-control safekeeping.

Are safe deposit box contents FDIC insured?

No. FDIC insurance covers deposits, and a safe deposit box is a rental of space, not a deposit. If contents are lost or damaged, the renter's recourse depends on the rental agreement, state law and their own insurance. Banks should say this clearly in the rental agreement and at account opening, because the misunderstanding is common and leads to complaints.

Are savings bonds found in a safe deposit box sent to the state?

Not necessarily. Treatment depends on the state. New York's guidance for banks, for example, says not to report Series E, EE or I savings bonds to the state but to retain them or forward them with a letter to Treasury Retail Securities Service. Other states give their own instructions, so check before including bonds in a report.
