What Your Montana Landlord Does Owe You

Interest or not, Montana law gives you real protections on your security deposit:

  • 30-day return deadline. Your landlord has 30 days after you move out to return your deposit or provide an accounting of deductions.
  • Itemized statement required. Your landlord cannot just keep part of your deposit — they must provide a written, itemized list of every deduction and its amount within 30 days.
  • Penalties for violations. If your landlord misses the deadline or makes illegal deductions, Montana courts can award you the deposit plus additional penalties.
