Detailed Answer

Short answer: In Montana, the contents of a deceased person’s safe deposit box generally become part of the decedent’s estate. Access usually goes to the personal representative (executor or administrator) or to a surviving co-tenant named on the box, and banks will typically require proof of authority (death certificate plus letters testamentary or letters of administration) or a court order before surrendering the box or its contents. If no one claims the property and it becomes abandoned, it may be turned over to the state’s unclaimed property program.

How banks typically handle safe deposit boxes after a death

When a bank learns a box-holder has died, most Montana banks will seal or restrict access to the safe deposit box to preserve estate property. The bank’s policies vary, but common steps include:

• Requesting a certified copy of the death certificate.
• Refusing to open the box for family members unless they also appear on the rental agreement (co-tenant) or can show legal authority.
• Requiring presentation of letters testamentary (if there is a will) or letters of administration (if there is no will) that name the personal representative. If the estate is not yet probated, the bank may require a court order allowing access.
• Sometimes allowing the personal representative to inventory the contents in the presence of a bank officer and to remove items after presenting proper documents.

Who can get access?

• Joint renters or co-tenant listed on the rental agreement: If the safe deposit box agreement names a joint renter or co-tenant with rights of survivorship, that person may have immediate access depending on the bank’s policies and the wording in the contract.
• Personal representative (executor/administrator): If the decedent’s estate is opened in probate, the personal representative identified by the probate court (who holds letters testamentary or letters of administration) can generally obtain access and take control of box contents on behalf of the estate.
• Heirs or beneficiaries: Heirs do not automatically get the box contents unless the personal representative distributes them according to the will or Montana probate law. If someone believes they are entitled to the contents but lacks letters, they may need to open a probate or bring a court proceeding.

When a court order is needed

If there is a dispute (for example, competing family members or no nominated personal representative) or if the bank will not release the contents without formal authority, the court can issue an order directing the bank to allow access. A common route is filing a petition in probate court for appointment of a personal representative or for an order authorizing access to specific property.

Small estates and informal procedures

Montana provides streamlined procedures for small estates that can make it easier to collect assets without full probate. If the safe deposit box contents are within the limits for a small estate and the statutory requirements are met, an heir may be able to obtain items using those procedures instead of a full probate. The exact threshold and steps change over time—check current Montana probate rules or consult probate counsel.

Unclaimed property

If no one claims the contents and the bank determines the property is abandoned under Montana’s unclaimed property rules, the bank may report and deliver those assets to the Montana State Treasurer’s unclaimed property office. The state then holds the property and makes it available for claim by the rightful owner or heirs.

Key Montana law sources

Matters involving safe deposit boxes touch both banking contract law and probate law in Montana. For the governing statutes and probate rules, consult the Montana Code Annotated and Montana courts resources (for probate rules and forms):

• Montana Code Annotated (MCA): official statutes and titles — visit the Montana Legislature site: https://leg.mt.gov/bills/mca/
• Montana State Treasurer — Unclaimed Property: https://treasurer.mt.gov/Unclaimed-Property

Practical hypothetical example: Jane Doe dies leaving a safe deposit box. The bank seals the box when it receives the death certificate. Jane named her sister as a co-tenant on the box; the sister can usually access the box after presenting ID and the bank’s paperwork. If Jane’s will names an executor who is not the co-tenant, the executor must present letters testamentary to take custody of items and distribute them according to the will. If there is no will and multiple family members claim items, the bank may demand a court order before releasing the box contents.

Helpful Hints

• Contact the bank immediately after the death to learn its specific policies and required documents.
• Obtain multiple certified copies of the death certificate early—banks and courts commonly require them.
• If you anticipate opening a safe deposit box after someone dies, locate the rental agreement; it often names co-tenants or gives instructions that affect access.
• If you are the executor, get letters testamentary or letters of administration from the probate court before asking the bank to release items.
• If family members disagree, consider mediation or consult an attorney before pursuing court action; court proceedings add time and cost.
• Search the Montana State Treasurer’s unclaimed property database if you believe items were turned over to the state: treasurer.mt.gov/Unclaimed-Property.
• Keep an inventory and receipts when removing items from a safe deposit box; that documentation helps the executor with estate accounting.
• If time is urgent (for example, to preserve perishable items or evidence), ask the bank whether it will open the box in the presence of the personal representative and bank personnel or whether the court can issue an expedited order.
