What happens to a safe deposit box after someone dies in Michigan?

Short answer: In Michigan a safe deposit box does not automatically pass outside the decedent’s estate unless it was jointly held with a right of survivorship. Banks generally will restrict access at the decedent’s death, and the box’s contents usually become property of the decedent’s estate until a personal representative (executor/administrator) or a court orders otherwise. If the box contains a valid will or items subject to transfer outside probate (for example, property titled in joint names), different rules may apply.

Detailed answer

This section explains, in plain language, what typically happens and what you should expect under Michigan procedure when someone who leased a safe deposit box dies.

1. Immediate bank reaction

When a bank learns a box holder has died it commonly:

refuses routine access using the former key;
seals the box or places it under temporary hold;
asks for a certified copy of the death certificate;
informs the family that access requires either the personal representative’s authority (letters testamentary/letters of administration) or a court order.

These steps protect the bank from liability if someone takes property without proper authority.

2. Who can get into the box?

Joint tenant with right of survivorship: If the box was leased in two names with survivorship language, the surviving co-tenant typically can access the box and the contents pass to the survivor by operation of law.
Authorized users/agents: If someone was listed on the lease as an authorized user, bank policy controls whether that person can access the box after death. Many banks limit or revoke that access when the principal dies.
Personal representative (executor/administrator): If someone has been appointed by the probate court and has official letters, banks usually accept those letters and will allow the personal representative to open the box or will open it in the presence of the representative and bank staff.
No appointed representative: If no one has been appointed, the bank will typically insist on a court order (probate court) allowing access or an order permitting the retrieval of specific items (for example, a will).

3. What if the box contains the decedent’s will?

Banks often have procedures that allow the will to be removed from the safe deposit box and delivered to the probate court or to the person who will open probate. In many cases the bank will open the box in the presence of a court officer or after receiving a court order so the will can be inventoried and filed with probate.

4. Ownership and probate

Unless an item in the box passed to someone outside probate (for example, a jointly owned asset), the contents are generally estate property. The personal representative collects estate assets, inventories them, pays debts and distributes to beneficiaries according to the will or Michigan intestacy rules.

5. How access is obtained (typical steps)

Locate the box lease agreement and keys, if possible.
Contact the bank, provide the decedent’s death certificate, and ask about the bank’s required documents and the bank’s policy for opening the box after death.
If a will exists, consider filing it with probate court so a personal representative can be appointed.
If probate is opened and a personal representative is appointed, present the letters of appointment to the bank. The bank will usually allow access or open the box in the representative’s presence.
If no representative is appointed or if the bank refuses to open the box, file a petition in probate court requesting an order to open the box and inventory or to retrieve particular items (for example, a will or cash needed for immediate expenses).

6. Timing and costs

Expect some delay. Banks move carefully to avoid wrongful release. Probate filings, court orders, and bank fees (for opening and inventorying a box) can cause additional time and cost. If immediate access to specific items is necessary (e.g., identification, financial documents, the will), probate courts may issue expedited orders in appropriate circumstances.

7. Risks of taking matters into your own hands

Do not attempt to open a safe deposit box without authority. Unauthorized access can lead to criminal charges and civil liability. Always coordinate with the bank and, if needed, the probate court.

Practical checklist for someone dealing with a decedent’s safe deposit box in Michigan

Find the box lease and keys, if possible.
Get several certified copies of the death certificate.
Contact the bank immediately to learn its required procedures and fees.
Locate and review the decedent’s will, if any; file it with probate court as soon as possible.
If you will act as personal representative, file for appointment with the probate court so you can present letters to the bank.
If urgent access is needed and no representative exists, petition the probate court for an order allowing limited access.
Keep a written inventory and receipts for any items removed from the box, and follow probate accounting rules when distributing estate property.

When to consult a Michigan probate attorney

Consider consulting an attorney if:

The bank refuses access despite letters of appointment;
The box contains large sums of cash, securities, or property with disputed ownership;
Multiple people claim rights to the contents;
You need an expedited court order to retrieve a will or urgently-needed documents;
The estate is complex or likely to be contested.

Helpful Hints

Do not try to force open a box or use bolt-cutters. Always follow bank procedure.
Keep multiple certified death certificates on hand—they are often required by banks, financial institutions, and government agencies.
If the decedent named a trusted person as a joint lessee, ask the bank what paperwork demonstrates survivorship rights.
Inventory everything removed from the box in writing, and keep witnesses and receipts when possible.
Expect bank fees for opening and inventory; ask for an estimate up front.
If the will is inside the box, file it promptly with probate court to avoid delay in appointing a personal representative.
If you are a personal representative, bring certified letters of appointment to the bank—banks usually accept these as authority to access the box.
