How to Sue a Contractor in Montana Small Claims Court Step by Step
If a contractor took your deposit and abandoned the job, left defective work, or refused to finish what they agreed to do, Montana small claims court is likely the right place to recover your money — as long as the amount is $7,000 or less. Here is exactly how the process works, what it costs, and what you need at each step. Contractor disputes are among the most common cases in Montana Justice Courts, and the procedure is the same whether you are dealing with a general contractor, a roofer, a plumber, or a landscaper.
Step 1: Confirm Your Claim Qualifies
Montana small claims jurisdiction is limited to claims for fixed, easily calculable money amounts up to $7,000 under MCA § 25-35-502. For contractor disputes, this means:
Qualifies: You paid a $3,000 deposit and the contractor did no work — your claim is $3,000 (the deposit). You paid $5,000 for a bathroom remodel and the contractor completed half — your claim is the portion you paid for work not received.
May not qualify: You want damages for "poor quality work" but cannot put a specific dollar figure on the repair cost. Small claims requires a liquidated (fixed) amount. Get repair estimates from other contractors before filing — those estimates become your claim amount and your evidence.
Does not qualify: Your total damages exceed $7,000. You can waive the excess and file for $7,000, or file in the General Civil Division of Justice Court (up to $15,000) or District Court (no limit). You cannot split the claim into two small claims cases.
Step 2: Identify the Contractor Correctly
This step prevents the most common filing mistake in contractor cases: suing the wrong legal entity.
If the contractor operates as an LLC or corporation, identify the business using its registered legal name and designated registered agent. Check the Montana Secretary of State's online business registry. The complaint must name the entity exactly as registered — "Mountain View Construction LLC," not "Mountain View Construction" or "Joe's construction company." Whether the individual owner is also a proper defendant depends on the basis for the claim.
If the contractor is a sole proprietor using a trade name, name both: "Joseph Smith d/b/a Mountain View Construction." This ensures the judgment is enforceable against the individual personally.
If you do not know the business structure, the Secretary of State's registry search is free and takes two minutes. An incorrect defendant name can make a judgment unenforceable against the intended party.
Step 3: Send a Demand Letter
Before filing, send a formal written demand by certified mail with return receipt requested. The letter should state:
- The work agreed to and the amount paid
- What went wrong (abandoned, incomplete, defective)
- The specific dollar amount you are claiming
- A deadline for payment (10–14 days is a reasonable compliance window)
- That you will file a small claims complaint if payment is not received
Several Montana Justice Courts — including Park County, Madison County, and Ravalli County — require proof of a certified-mail demand before they will accept your complaint. Even where not required, the demand letter shows the judge you tried to resolve it first, and it sometimes produces payment without a court filing.
Keep the certified mail tracking receipt and the signed (or refused) return card. You will present these to the clerk when filing and to the judge at the hearing.

Step 4: File the Complaint
Take the completed Small Claims Complaint and Order of Court form to the Justice Court clerk in the county where the contractor resides or can be served. You can download the form from courts.mt.gov.
Filing fee: $10 statutory base under MCA § 25-35-608(1)(a); Park and Carbon Counties list a $30 total small-claims filing fee. Verify your county's amount and accepted payment methods with the clerk. Park County accepts only cash or check.
What goes on the form: Your name and address, the contractor's legal name and address, the amount claimed, and a brief statement of why the money is owed. Keep the statement factual: "Defendant received $3,000 deposit for bathroom remodel on [date], abandoned the project on [date], and has not returned the deposit despite certified-mail demand sent [date]."
The court sets a hearing date between 10 and 40 days from the date the Order of Court is issued.
Step 5: Serve the Contractor
You cannot serve the papers yourself. Under MCA § 25-35-604, service may be made by a sheriff or constable, a private process server, or another disinterested adult over 18 who is not a party; the court clerk may also send the papers by certified or registered mail with restricted delivery and return receipt. Service must be complete at least 5 days before the hearing under MCA § 25-35-603.
Sheriff service fees vary by county. Carbon County's sheriff charges $65 per person plus a $15 processing fee. Confirm other counties' current fees with the local sheriff or court clerk. A private process server may cost more but offers scheduling flexibility.
If service cannot be completed at least 5 days before the hearing, request an alias order resetting the appearance date. A private process server is another option for completing service. Service failure is the most common delay in contractor cases because contractors who owe money sometimes make themselves hard to find.
Track every service attempt — date, method, result. The court needs proof that service was completed before the hearing can proceed.
Step 6: Prepare Your Evidence
Justices of the Peace decide contractor cases on the evidence presented. Prepare three identical sets — one for the judge, one for the contractor, one for yourself — organized chronologically with tabbed dividers.
Essential evidence for contractor disputes:
- The written contract, estimate, or text/email agreement showing the work scope and price
- Proof of payment (bank statements, cancelled checks, Venmo/Zelle screenshots)
- Photos of the work site — before, during, and current condition
- The demand letter and certified-mail receipt
- Repair estimates from other contractors showing the cost to fix or complete the work
- Text messages, emails, or voicemails documenting the contractor's failure to return or perform
- Witness statements from anyone who observed the work (or lack of it)
What judges do not want to see: A phone screen held up in court. Print everything. Organize chronologically. Label each exhibit.
Step 7: Attend the Hearing
Small claims hearings are informal — no jury, and attorneys may appear only when all parties are represented by counsel under MCA § 25-35-505(2). Strict evidence rules are relaxed. The Justice of the Peace typically hears each side's account, examines the evidence, asks questions, and issues a decision.
If the contractor does not appear, you can request a default judgment for the full amount claimed. If the contractor appears and disputes the claim, the judge weighs both sides' evidence.
Decisions are usually issued the same day or mailed within a few days. If you win, the judgment includes the amount owed plus your court costs.
What Happens After You Win
A judgment is a court order that the contractor owes you money. It is not an automatic payment. If the contractor does not pay voluntarily, once the judgment is final and non-appealable you can pursue post-judgment enforcement under regular Justice Court procedures:
- Wage garnishment — if the contractor is employed
- Bank levy — if you know the contractor's bank
- Property lien — record a judgment lien against personal property
For contractors who are LLCs or corporations, the judgment attaches to the business entity. For sole proprietors named individually, personal assets are reachable.

Who This Is For
- Montana homeowners whose contractor took a deposit and disappeared or abandoned the job
- Anyone who paid for construction, repair, or renovation work that was never completed or was defective
- People whose contractor dispute is $7,000 or less and who have documentation of the agreement and payments
- DIY litigants willing to invest 8–15 hours over 6–10 weeks to recover their money
Who This Is NOT For
- Homeowners whose dispute exceeds $7,000 and who do not want to waive the excess
- People without any written agreement, payment proof, or documentation — you can still file, but the case becomes your word against theirs
- Anyone looking for a lawyer to handle the case — small claims is self-service, and attorneys are barred under MCA § 25-35-505(2) unless all parties are represented
- Disputes over work quality where you cannot put a specific dollar figure on the repair cost (get estimates first)

Frequently Asked Questions
What if the contractor threatens to bring a lawyer?
Under MCA § 25-35-505(2), an attorney cannot appear in the Small Claims Division unless all parties are represented by counsel. A defendant seeking legal representation can remove the action to regular Justice Court by filing a Notice of Removal within 10 days after service.
Can I sue for more than the contract price?
You can claim the amount you paid for work not received, plus a fixed, supported cost to repair defective work, up to the $7,000 limit. The Small Claims Division excludes unliquidated general tort damages, including pain-and-suffering or emotional-distress amounts.
What if the contractor files a counterclaim?
Under MCA § 25-35-606(2), the contractor can counterclaim up to $6,500 — for example, claiming you owe for additional work performed. Bring documentation that contradicts any potential counterclaim, such as the original scope of work and proof of all payments made.
How do I find out if the contractor is licensed?
Since January 1, 2026, Montana's construction contractor registration program has transitioned to a Contractors License administered by the Department of Labor & Industry (DLI), with exemptions including some independent contractors who have no employees. Check DLI's contractor license records for current status, and the Secretary of State registry for an LLC or corporation's legal name. A licensing issue is separate from proving your claim; bring the contract, payment records, and evidence of unfinished or defective work.
What if the contractor has no money or assets?
This is the collection risk. A judgment against a defunct business or an individual with no assets may be difficult to collect. Before filing, consider whether the contractor has a going business, local property, or regular employment. If the contractor is still operating and taking deposits from other customers, collection is usually feasible.
