In Montana, what does the law say about security deposit, return deadline?
Answered for: Montana
Each landlord, within 30 days subsequent to the termination of a tenancy or within 30 days subsequent to a surrender and acceptance of the leasehold premises, whichever occurs first, shall provide the departing tenant with a written list of any rent due and any damage and cleaning charges
This is Montana's statute on security deposit, return deadline, in its own words.
