Return security deposit with itemized statement within 30 days of move-out. Montana landlords must deliver a written list of any rent due and damage and cleaning charges, together with the remaining deposit balance, within 30 days after the tenancy ends or the landlord accepts the tenant's surrender of the unit, whichever comes first (or return the full deposit within 10 days when there is no damage, cleaning, unpaid rent, or unpaid utilities), and a landlord who skips the list forfeits the right to keep any of the deposit for damage or cleaning.
