Who the deadlines apply to
Wyoming's timetable sits in Wyo. Stat. tit. 29, chs. 1 and 2, and no rule on this page is limited by project type.
At the preliminary notice stage, the statute sets the contractor apart from the subcontractor or materialman, and at lien filing it sets any contractor apart from every other person asserting a lien [1]. On this page the contractor's rows name the direct contractor. The rows for the second group name subcontractors, sub-subcontractors, suppliers and laborers, and the preliminary notice row for that group also cites W.S. 29-1-201(a)(vi), where "Subcontractor" is defined [1].
The notice of intention, the notice sent after filing and the deadline to sue each name all five roles.
How the periods run
Preliminary notice. Under W.S. 29-2-112(a), the direct contractor's notice runs Before receiving any payment from the owner, including advances [1]. That rule turns on a payment, not a date, so the calculator counts nothing for it. For subcontractors, sub-subcontractors, suppliers and laborers, the rule is 30 days after first providing services or materials to the construction project [1]. Section 29-2-112(a)(iii) says failure to send the notice within the time specified bars the right of a contractor, subcontractor or materialman to assert a lien [1].
Notice of intention. Section 29-2-107(a) places a written notice of the claim ahead of the lien filing, under the rule No later than twenty (20) days prior to filing a lien statement [1]. The period is counted back from the filing itself, so no date is drawn for it.
Filing the lien statement. Section 29-2-106(a) gives the direct contractor the earlier of 150 days after the last day when work was performed or materials furnished under contract and 150 days after the date of substantial completion of the project [1]. Every other person asserting a lien has the earlier of 120 days after the last day when work was performed or materials furnished under contract and 120 days after the date of substantial completion of the project [1], a row that names subcontractors, sub-subcontractors, suppliers and laborers.
With respect to a subcontractor, subsection (a)(ii) supplies a separate rule: 120 days after the last day he performed work at the direction of the contractor or other person authorized to provide direction [1]. That row names subcontractors, sub-subcontractors and laborers. This page does not say which of these rules governs a given project.
After filing. The lien claimant sends notice to the last record owner or his agent under the rule 30 days after the lien statement is filed [1]. Under W.S. 29-1-312(c), failure to send it does not affect the validity of the lien [1].
The suit. Every action to foreclose or enforce a lien under the chapter is commenced within 180 days after the lien statement is filed [1]. Section 29-2-109 adds that no lien continues to exist under the chapter for more than that period after it is filed unless an action to foreclose the lien is instituted [1].
Notices of completion
Section 29-2-106(c) lets the record owner record a notice of substantial completion of the project with the county clerk. The date it is recorded is presumed to be the date of substantial completion [1]. After recording, the record owner sends a copy within five days [1] to every contractor, subcontractor and materialman who gave the owner a preliminary notice.
The notice does not extend the time to file a lien statement. That time is also not affected if the record owner fails to send the copy [1].
