Late Rent Notice Requirements in Montana 2025
Grace period, late fee cap, and pay-or-quit notice rules
In Montana, rent is late the moment it is unpaid when due. There is no statutory grace period. But being late does not by itself end the tenancy. Before a landlord can file for eviction over nonpayment, the Montana Residential Landlord and Tenant Act of 1977 requires a written 3-day notice to pay rent or quit under MCA 70-24-422. Get the content or the service method wrong and a judge can dismiss the case, sending you back to day one. This page covers what the notice must say, how to serve it, how the mailing rule changes your timeline, and when a shorter repeat-violation notice applies.
The 3-day notice under MCA 70-24-422
Under MCA 70-24-422, if rent is unpaid when due and the tenant fails to pay within 3 days after written notice, the landlord may terminate the rental agreement and the tenant must vacate. The clock only starts once the tenant has received proper written notice of the nonpayment and of your intention to terminate if the rent is not paid in that window.
Montana counts this as a hard prerequisite: a landlord cannot bring an eviction for nonpayment without first serving a compliant 3-day notice. There is no obligation to offer a grace period beyond this statutory notice, and none is implied by state law.
What the notice must contain
To satisfy 70-24-422, the notice must state the amount of unpaid rent owed and make clear that the landlord intends to terminate the rental agreement if the tenant does not pay in full within the 3-day period. Practical drafting points:
- State the exact dollar amount of rent due. Do not fold in late fees, utilities, or damages you want to demand as a condition of curing, unless they are unambiguously rent under your lease, as padding the figure can invalidate the notice.
- Identify the tenant and the rental address, and date and sign the notice.
- State plainly that the tenant has 3 days to pay or the tenancy will be terminated.
If the tenant pays the full unpaid rent within the 3 days, the tenancy is reinstated and you cannot proceed. After the period expires, you may refuse a late payment and move forward with eviction.
How to serve the notice (MCA 70-24-108)
Montana's service rules for notices are set by MCA 70-24-108. Valid methods include:
- Personal hand delivery to the tenant.
- Mailing with a certificate of mailing or by certified mail to the tenant's designated address or, absent one, the last known address.
- Electronic mail to an email address the tenant provided in the rental agreement. Electronic service is complete only on a read receipt or a non-automated reply, not on send.
A process server or sheriff is not required to deliver the notice itself. Even so, keeping proof of delivery matters if the tenant later disputes receipt.
The mailing rule adds 3 days to your timeline
Service method changes when the clock starts. Under MCA 70-24-108, when you serve by certificate of mailing or certified mail, service is deemed made 3 days after the date of mailing. The tenant's 3-day cure period runs from that deemed-service date, not from the postmark.
In effect, a mailed 3-day notice gives the tenant roughly 6 days before you can act. If you need the shortest reliable timeline, hand-deliver the notice so the 3 days begin on the day of delivery, and document who delivered it and when.
Repeat late payment and the federal exception
For a recurring problem, 70-24-422 offers a faster route. If substantially the same noncompliance that you previously noticed recurs within 6 months, you may terminate on at least 5 days' written notice without giving another chance to cure that repeated breach. Document the first notice carefully so you can rely on this provision later.
One federal overlay matters: for federally backed or federally subsidized housing, the CARES Act still requires 30 days' notice to vacate for nonpayment, which preempts Montana's 3-day notice at those properties. Confirm your property's financing before relying on the 3-day rule.
The Pay-or-Quit Notice Process in Montana
Once rent is late and no grace period applies, the landlord must serve a formal 3-day pay-or-quit notice (Mont. Code § 70-24-422) before filing for eviction. This notice must state the total amount owed and give the tenant the option to either pay in full or vacate. If the tenant does neither, the landlord may file an unlawful detainer action in Montana court.
- Rent due date: As stated in the lease
- Pay-or-quit notice may be served: Day 1 or later
- Notice period expires: Day 3 after the due date
- Eviction filing permitted: Day 4 or later

Frequently Asked Questions
How many days is Montana's late rent notice?
Three days. Under MCA 70-24-422, the landlord must give written notice of nonpayment and intent to terminate, and the tenant has 3 days to pay in full before the landlord can terminate the tenancy and proceed to eviction.
Does Montana require a grace period before rent is late?
No. Montana law provides no statutory grace period. Rent is late when it is unpaid on the due date, though the tenancy cannot be ended until you serve a compliant 3-day pay-or-quit notice under MCA 70-24-422.
How must the 3-day notice be delivered in Montana?
Under MCA 70-24-108, you may hand-deliver it, mail it with a certificate of mailing or by certified mail, or email it to an address the tenant gave in the rental agreement (with email service complete only on a read receipt or non-automated reply). A process server is not required.
Does mailing the notice change the timeline?
Yes. When served by certificate of mailing or certified mail, MCA 70-24-108 deems service made 3 days after the mailing date, so the tenant's 3-day cure period effectively begins 3 days later. Hand delivery avoids that add-on.
What must the Montana pay-or-quit notice say?
It must state the amount of unpaid rent and that the landlord intends to terminate the rental agreement if the rent is not paid within 3 days. Avoid bundling late fees or other charges into the rent figure, which can invalidate the notice.
Can I use a shorter notice for a tenant who is repeatedly late?
If substantially the same violation recurs within 6 months of a prior noticed breach, MCA 70-24-422 lets you terminate on at least 5 days' written notice for that repeat. For federally backed or subsidized units, the CARES Act 30-day notice-to-vacate requirement may still apply.
