Montana Security Deposit Planner

Cleaning — only if the landlord first gave written notice of what to clean and 24 hours to do it (exception: you moved out without proper notice).

Damage — only for harm you or your guests caused, not pre-existing damage.

Normal wear and tear — cannot be deducted (faded paint, small nail holes, worn carpet paths).

Unpaid rent & utilities — allowed if they were your responsibility and truly unpaid.

Late fees / other lease charges — only if your lease clearly names them. 70-25-201, MCA ↗

How long do they have to return my deposit? Montana has a 10-day no-deduction provision, but that subsection does not state its trigger. Paper Alibi shows a limited connected-statute reading only when the landlord statement, prior-inspection, and utility conditions are supported. If money is kept, the 30-day period runs from tenancy termination or surrender and acceptance, whichever occurs first.

Can they charge for small nail holes? No — that's normal wear and tear.

What if I never got an itemized list? If the landlord did not provide a list within the supported 30-day period, the landlord may lose the right to keep money for cleaning or damage. Check whether the landlord claims notice by certified mail, a certificate of mailing, hand delivery, or another method. 70-25-202, MCA ↗

How can the landlord pay me back? As of 2025, Montana lets the landlord return your refund by electronic funds transfer, cash, check, other forms of refund, or by mailing it to the address you gave (or your last-known address if you did not give one). 70-25-202, MCA ↗

What if the landlord never gave me a move-in condition statement? A landlord who requires a deposit must give you a separate written statement of the unit's condition at move-in. If they did not, they generally cannot keep money for damage or cleaning unless they prove by clear and convincing evidence that you caused it. 70-25-206, MCA ↗

Pause before you sue. A court case carries risk. Your past landlord can file a counterclaim. You could lose, and you could owe money. If the other side hires a lawyer and wins, the court may order you to pay their fees. Talk to a lawyer if you are unsure.

All of this comes from Montana's free official packet, Filing a Complaint to Ask for Your Security Deposit Back, linked below. It's a summary, not advice — the packet says the same. We do not sell or copy the official court forms — we link you to the free public versions and help you organize what goes into them.

The process, in order — (1) fill out the Complaint and Request to Serve Documents; (2) fill in only the caption on the Summons, Order Setting Trial, and Judgment — the court completes the rest; (3) make copies; (4) file with the clerk, fee waiver first if you need one; (5) have the sheriff serve each defendant; (6) file the Proof of Service; (7) wait for the Answer; (8) go to your hearing.

When an action may be maintained — Section 70-25-204(2), MCA, lists alternative paths joined by “or”: written denial received; 30 days after tenancy termination; 30 days after surrender and acceptance; or 10 days after the landlord indicated that all listed no-deduction conditions existed. Which path applies depends on the facts. Check the current statute and official packet before filing.

Who to sue — whoever makes decisions about the deposit, usually whoever signed your lease as landlord. You can always sue the owner, with or without a property manager. Don't sue employees like maintenance workers.

Where to file — the county where the landlord lives or where the rental sits. Justice, city, and municipal courts (courts of limited jurisdiction) are usually the better choice for deposits of $15,000 or less; district court can take longer.

Forms you'd file — Complaint, Summons, Request to Serve Documents, Order Setting Trial, and Judgment. If you can't afford the filing fee, file a Statement of Inability to Pay (fee waiver) before your Complaint, and give the judge time to approve it. Use the official forms exactly as published — do not change them. The packet warns that changing them can delete language you need.

Serving the landlord — each defendant must be personally served; you can't hand over the papers yourself. The sheriff serves them — free only if the defendant lives in Montana and you have a fee-waiver order. For a company, serve the manager or its registered agent (find it through the Montana Secretary of State).

Deadlines — the landlord has 20 days to file an Answer (21 in District Court). If they file a counterclaim, you have the same 20 or 21 days to file a written Response. No Answer at all? You can ask for a default judgment.

Risks — the landlord can counterclaim, and you could end up owing money. If they hire an attorney and win, the judge can order you to pay those attorney fees, which can top $1,000. Even a strong case can lose.

Jury trial — you have the right to one, but you pay the jury costs. To ask for one, print “I REQUEST A JURY TRIAL” under the word “Complaint” on the first page. If you skip it, the judge decides.

If you win — the judgment may include the wrongfully withheld deposit, court costs, and post-judgment interest at the rate set by § 25-9-205, MCA. The general rate is the bank prime rate plus 3%, set for the year, unless a contract-based exception applies. § 25-9-205, MCA ↗
