Preliminary Notice Requirements in Missoula County

If you're working on a construction project in Missoula County, Montana, here's the most important thing to understand about preliminary notices: Montana law REQUIRES you to send one. It's called the "Notice of Right to Claim a Lien" and it must be sent within 20 days of when you first start working or delivering materials to the project. Sending it on time keeps your lien rights active and all your options open.

Let's say you're a subcontractor hired to do HVAC installation on a new building in Missoula County. Your first day on-site is March 1st.

It's not confrontational — it's standard paperwork that protects your right to get paid.

All preliminary notice requirements in Missoula County come from Montana state law (MT Code Ann. §§ 71-3-521 et seq.). The rules are the same across every county in Montana — but when it comes time to actually file a mechanics lien, you'd file it at the Missoula County Recorder's office.

You have 90 days from last provision of services or materials to file. File within this window to keep your lien rights protected.
