The short answer
The current statute provides six years for an action founded on an instrument in writing, five years for an unwritten contract, account or promise, and three years for other unwritten obligations or liabilities. The former eight-year written-contract figure is outdated for the current statutory text.
The Montana rule to identify first
The current statute provides six years for an action founded on an instrument in writing, five years for an unwritten contract, account or promise, and three years for other unwritten obligations or liabilities. The former eight-year written-contract figure is outdated for the current statutory text.
- Covered claim: Contract, covenant, obligation or liability founded on a written instrument, subject to classification and applicable-law review.
- Starting event: Under §27-2-102, accrual occurs when all claim elements exist and the right to maintain the action is complete; commencement is filing the complaint.

What can change the period
- 2025 Chapter 174 §3 specifies applicability to written-instrument actions filed on or after October 1, 2025. Historical claims and transition questions require legal review; do not assume an old eight-year chart applies.
- Official session law: (see linked source) (PDF page 824, section 3).
- Accrual source: (see linked source)
- Special statutes, payments, acknowledgments and tolling require separate review. Checked October 19, 2026.

Build the right timeline before making a payment
The first collection letter, the charge-off date, the date the account was sold and the date a lawsuit was filed are different events. A last-payment date alone cannot establish which legal claim is being sued on, which state’s law applies, whether the period was paused or whether a judgment already exists.
| Record | Why it matters |
|---|---|
| Original contract and amendments | Identifies the obligation, governing-law clause and any installment terms. |
| Full payment and charge history | Helps identify default, later payments and any claimed restart. |
| Default or acceleration notices | May matter for installment obligations or a demand for the entire balance. |
| Complaint and service papers | Show the actual claim, filing date, court and separate response deadline. |
| Prior judgment, bankruptcy or earlier lawsuit | Can change the legal framework or pause/extend particular periods. |
If you have already been sued
Montana Legal Services Association distinguishes a 20-calendar-day answer period in Municipal, City and Justice Court from 21 days in District Court, counted from the day after service. It also explains weekend and holiday adjustment. Tribal court or out-of-state proceedings require different rules.
A limitation defense and a court-response deadline are separate questions. Keep the defense available through the proper filing or hearing procedure even while you request records or discuss settlement. A collector’s promise to review an account is not a court extension.

Court collection and credit reporting are separate
An account disappearing from a credit report does not establish that a lawsuit is too late. Likewise, a limitation period expiring does not by itself erase all records of the account. Federal collector rules restrict suing or threatening suit on time-barred debt, but the applicable state rule and the collector’s role still need to be identified.

Questions worth asking
- Can I calculate this from my last payment date?
- Does selling my account start a new period?
- Should I make a small payment on an old account?
Common questions
Can I calculate this from my last payment date?
Not reliably. The type of claim, accrual event, governing law, later activity and any pause or judgment can change the analysis. This guide supplies source rules, not an individualized finding that your debt is time-barred.
Does selling my account start a new period?
A sale to a collector is not by itself proof of a new cause of action. Obtain the original account timeline and investigate any alleged later payment or agreement.
Should I make a small payment on an old account?
First verify ownership, amount and the timing rules. Depending on the applicable law and whether the period has expired, a payment or written promise can affect your defenses.
