3 deadlines NoticeGuard models for Wyoming: what each one counts from, the statute it was read from, and the statute text.
Information, not legal advice. This app reports what the statute says and cites the section it read. It is not legal advice, it does not file anything for you, and it does not tell you what to do.
Verify with the statute or an attorney. Statutes change, and courts reinterpret them. Every deadline in this app comes from a statute read on the date shown next to its citation - that snapshot can go out of date. Missing a mechanics lien deadline can extinguish your claim permanently, so confirm any deadline you are relying on with an attorney licensed in that state before you act on it.
Data verified: statute text retrieved 2026-09-21 (each citation below carries its own date). Rule data from the NoticeGuard app, source commit 22f9300.

Also stated next to this deadline.
No contract between the owner and the contractor can restrict a subcontractor's or materialman's own right to file a lien (§ 29-2-106(b)).
Commence action to foreclose or enforce the lien
Counted from the date the lien statement was filed. The lien stops existing after this period unless an action has been commenced.

Wyo. Stat. § 29-2-109 (sole operative sentence) Official source · statute text retrieved 2026-09-21
“All actions to foreclose or enforce a lien under this chapter shall be commenced within one hundred eighty (180) days after the filing of the lien statement. No lien shall continue to exist except by virtue of the provisions of this chapter for more than one hundred eighty (180) days after the lien is filed unless an action to foreclose the lien is instituted.”
If the date is missed (the statute's own terms). The statute's own mechanism: "No lien shall continue to exist... for more than one hundred eighty (180) days after the lien is filed unless an action to foreclose the lien is instituted."
Weekend and holiday rollover
NoticeGuard does not model a weekend or holiday extension for Wyoming. The dates above are the plain count from the date you enter. Check whether a Saturday, Sunday or holiday changes your date.
What this rule set does not cover
The notice of intention to file a lien (§ 29-2-107) is NOT modeled - it runs backward ("sent no later than twenty (20) days prior to filing a lien statement"), not forward from a fixed anchor this app's engine can express as a due date. The same discipline this app already applies to Colorado's backward-counted notice of intent.
The record owner's optional notice of substantial completion (§ 29-2-106(c)-(d)) does not change either filing deadline's length - it only creates a rebuttable presumption of the substantial-completion date itself. This app treats the substantial-completion date you enter as that date directly, whether or not a notice was recorded.
The agreement-to-extend-filing-period mechanism (§ 29-2-106(e), up to double the normal period) and the separate cooperative-utility lien (§ 29-2-106(f), 180/360 days) are not modeled - data-dependent and a narrow claimant category, respectively.
This app could not confirm, in this pass, whether Wyoming's lien statement has a statutory content-element list of its own (distinct from the notice-of-intention content referenced in § 29-2-107(b)) - no document is generated for this state until that is verified, rather than guessing at required content.
Weekend/holiday rollover is NOT modeled - no general Wyoming computation-of-time statute was researched this pass.
Sourcing gap, stated plainly: the statute text quoted here was read from Justia's Wyoming Statutes mirror - a commercial legal publisher - and not from the State of Wyoming's own site. Justia's mirror is reputable and labels itself current to 2025, but it is not the primary source and has not been re-verified word-for-word against the state's own page. Named for the same reason Arkansas's, Georgia's, New Mexico's and Tennessee's equivalent gaps are named.
Only §§ 29-2-106, 29-2-107, and 29-2-109 have been read closely. The rest of Chapter 2 - including the leasehold and tenant-improvement lien variants (§§ 29-2-104, 29-2-105) - was reviewed but not otherwise incorporated.
NoticeGuard is an app that turns a job's dates into a countdown for each statutory step, shows the statute text each date was read from, exports a calendar file (.ics) and sends reminders 14, 7 and 1 day before each deadline. It tracks and reminds; it does not file anything for you.
