Michigan § 487.3428 - Safe deposit and storage department.

If a savings bank operates a safe deposit and storage department, the legal liability of the savings bank on account of any loss to a customer shall not exceed the sum of $10,000.00 for any 1 box or compartment, including all property accepted for storage outside of the box or compartment. The savings bank may contract with the renter to have the renter assume all risks arising from the use of the box, compartment, or storage.

The savings bank shall have a lien for unpaid rental and storage charges on the contents of any box or compartment and any property accepted for storage outside of the box or compartment. If the charges are not paid within 1 year from the date of accrual, then the savings bank may sell the property at public auction upon like notice as is required by law for sales on execution.

After retaining from the proceeds of sale the amount of all charges due and owing at the time of the sale and the reasonable expenses of the sale, the savings bank shall pay any balance to the persons entitled to the proceeds. The savings bank may fairly and in good faith purchase all or part of the property at the sale.
