Montana Debt Collection Statute of Limitations

The dividing line that matters most for everyday collection is whether the obligation is founded on an instrument in writing. A signed promissory note or a written, signed loan agreement is a written instrument and sits in the six-year column. A revolving credit-card account, by contrast, is usually treated as an open account — the five-year column — unless a specific signed written agreement governs it. We unpack that credit-card question in its own section below, because it is where Montana files most often get the deadline wrong. These figures reflect Mont. Code Ann. 27-2-202 as published; the categorization of a particular debt can be contested, so treat this as general legal information and verify against the statute and a Montana attorney.

Knowing the length of the period is only half the calculation; you also need the start date. In Montana, a contract claim generally accrues — the clock starts — when the debt is breached. For an installment loan or a financed purchase, that is typically the first missed payment that was never subsequently cured. From that default date forward, the six-year or five-year period runs. Pinpointing that first uncured default is the heart of any Montana limitations calculation, and it is often buried in old payment records, which is one reason creditors reconstruct the account history before deciding whether a claim is still timely.

Open accounts have their own twist. An open account such as a revolving credit-card balance is generally treated as running the five-year period from the date of the last item or charge on the account — the most recent activity — rather than from the original opening date. That rule can move the deadline considerably: a long-dormant account that saw a late charge or final transaction more recently may still be inside the window. The practical lesson is that two facts drive everything — the correct category and the correct accrual date — and getting either wrong throws the whole deadline off.

Other doctrines can pause the clock. Under federal law, a bankruptcy filing imposes an automatic stay and 11 U.S.C. 108 can extend or toll certain deadlines while the case is pending; periods during which a defendant is absent from the state may also affect the count under Montana’s tolling provisions. These are fact-specific and beyond the scope of general information here — another reason to confirm any close deadline with a Montana attorney rather than rely on a back-of-envelope count.

Montana lets a limitations period begin running anew, and the rule is set out in Mont. Code Ann. 27-2-409. Two things can revive a debt. First, an acknowledgment or new promise — but it must be contained in some writing signed by the party to be charged. A debtor’s verbal “I know I owe you, I will pay” does not, by itself, restart the Montana clock; the acknowledgment has to be in a signed writing. Second, part payment — defined in the statute as any payment of principal or interest — is its own independent route that can cause the period to begin running anew from the date of that payment, without the formal signed writing required of an acknowledgment.

The part-payment rule is the one that surprises people. A single partial payment on a Montana written-contract debt can reset a six-year period, meaning a creditor’s enforcement window can stretch well past a decade from the original breach if the debtor pays even a little along the way. That is why collectors sometimes press for “just a small payment” on aged accounts — the payment itself can revive the deadline. A debtor who wants an old Montana debt to stay time-barred should be aware that making a payment, or signing anything that acknowledges the debt, may hand the creditor a fresh limitations period. As always, whether a particular communication or payment qualifies under 27-2-409 is a fact question best confirmed with a Montana attorney.
